Capture efficiency of fyke nets averaged 24% for four groups, about 300 tagged sea lampreys each, released upstream of the barrier; no unmarked sea lampreys and none of the 1,194 sea lampreys tagged and released downstream of the barrier were captured in the fyke nets while the barrier was energized. At a lower pulsator setting (1-ms pulse width; 10 pulses/s), 1 of 900 sea lampreys released below the barrier was recaptured in the nets. Sea lampreys from downstream were captured in the fyke nets after the barrier was de-energized, indicating that the barrier should remain in operation later than mid-July. Both sea lampreys and teleosts exposed to the electrical field were stunned but exhibited no apparent damage at either barrier setting. The pulsed-DC electrical barrier should help reduce the use of chemical lampricides for controlling sea lampreys in some Great Lakes streams and would be particularly suited for streams where even the smallest low-head barrier would create an unacceptably large impoundment.","language":"English","publisher":"Wiley","doi":"10.1577/1548-8675(1999)019<0397:EOAEBI>2.0.CO;2","usgsCitation":"Swink, W.D., 1999, Effectiveness of an electrical barrier in blocking a sea lamprey spawning migration on the Jordan River, Michigan: North American Journal of Fisheries Management, v. 19, no. 2, p. 397-405, https://doi.org/10.1577/1548-8675(1999)019<0397:EOAEBI>2.0.CO;2.","productDescription":"9 p.","startPage":"397","endPage":"405","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":131540,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Michigan","otherGeospatial":"Jordan River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -85.56897492191116,\n              45.56838743690551\n            ],\n            [\n              -85.56897492191116,\n              45.05736453200967\n            ],\n            [\n              -84.79395333073784,\n              45.05736453200967\n            ],\n            [\n              -84.79395333073784,\n              45.56838743690551\n            ],\n            [\n              -85.56897492191116,\n              45.56838743690551\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      },\n      \"id\": 0\n    }\n  ]\n}","volume":"19","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fde90","contributors":{"authors":[{"text":"Swink, William D.","contributorId":60586,"corporation":false,"usgs":true,"family":"Swink","given":"William","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":308633,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Tank-reared striped bass (120–200 mm total length) were tagged with coded wire tags and one of six types of internal anchor tags (500 fish each tag type and two groups of controls). The types of internal anchor tags used were as follows: Floy streamer FM-84 (currently in use by the U. S. Fish and Wildlife Service); Floy streamer with protective sheath (modified FM-84), Floy streamer with a monofilament leader and sheath (FM-89SL), modified Hallprint T687, Hallprint monofilament IEX WAD, and Hallprint T-bar IEX NOR. The Hallprint T-bar IEX NOR and the Floy FM-84 tags caused significantly higher 2-week and 6-month mortality. Final fish total length was different among tag types and tagger groups; however, final fish size was not correlated with either variable after adjusting for initial fish size. Tags were also mounted on polyvinyl chloride pipes and exposed to freshwater, brackish-water, and saltwater environments for 1 year. The brackish-water environment was harsher than either freshwater or salt water and had a greater density of fouling organisms. Legibility was poor for the Floy streamer, and Floy tag sheaths sometimes moved and obscured the printing. Failure rates (printing loss or tag loss) for the Floy tags (36%) were about six times higher than the Hallprint tags (6%). An analysis of 369 anchor tags returned by striped bass fishers indicated that the tag was illegible when more than 43 printed characters were lost and that illegibility increased over time. None of the tags tested was considered appropriate for tagging juvenile striped bass, but changes in tag design, material, and insertion could improve tag retention and survival.</span></p>","language":"English","publisher":"Wiley","doi":"10.1577/1548-8675(1999)019<0482:AEOSIA>2.0.CO;2","usgsCitation":"Henderson-Arzapalo, A., Rago, P., Skjeveland, J., Mangold, M., Washington, P., Howe, J., and King, T., 1999, An evaluation of six internal anchor tags for tagging juvenile striped bass: North American Journal of Fisheries Management, v. 19, no. 2, p. 482-493, https://doi.org/10.1577/1548-8675(1999)019<0482:AEOSIA>2.0.CO;2.","productDescription":"12 p.","startPage":"482","endPage":"493","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":131682,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad8e4b07f02db684898","contributors":{"authors":[{"text":"Henderson-Arzapalo, A.","contributorId":92607,"corporation":false,"usgs":true,"family":"Henderson-Arzapalo","given":"A.","email":"","affiliations":[],"preferred":false,"id":321377,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rago, P.","contributorId":42168,"corporation":false,"usgs":true,"family":"Rago","given":"P.","email":"","affiliations":[],"preferred":false,"id":321373,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Skjeveland, J.","contributorId":57418,"corporation":false,"usgs":true,"family":"Skjeveland","given":"J.","affiliations":[],"preferred":false,"id":321376,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mangold, M.","contributorId":47736,"corporation":false,"usgs":true,"family":"Mangold","given":"M.","email":"","affiliations":[],"preferred":false,"id":321375,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Washington, P.","contributorId":13930,"corporation":false,"usgs":true,"family":"Washington","given":"P.","affiliations":[],"preferred":false,"id":321372,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Howe, J.","contributorId":98679,"corporation":false,"usgs":true,"family":"Howe","given":"J.","email":"","affiliations":[],"preferred":false,"id":321378,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"King, T.","contributorId":46906,"corporation":false,"usgs":true,"family":"King","given":"T.","affiliations":[],"preferred":false,"id":321374,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Galileo gravity data verify that the satellite is differentiated into an outer H</span><sub>2</sub><span>O layer about 100 km thick but cannot determine the current physical state of this layer (liquid or solid). Here we summarize the geological evidence regarding an extant subsurface ocean, concentrating on Galileo imaging data. We describe and assess nine pertinent lines of geological evidence: impact morphologies, lenticulae, cryovolcanic features, pull‐apart bands, chaos, ridges, surface frosts, topography, and global tectonics. An internal ocean would be a simple and comprehensive explanation for a broad range of observations; however, we cannot rule out the possibility that all of the surface morphologies could be due to processes in warm, soft ice with only localized or partial melting. Two different models of impact flux imply very different surface ages for Europa; the model favored here indicates an average age of ∼50 Myr. Searches for evidence of current geological activity on Europa, such as plumes or surface changes, have yielded negative results to date. The current existence of a global subsurface ocean, while attractive in explaining the observations, remains inconclusive. Future geophysical measurements are essential to determine conclusively whether or not there is a liquid water ocean within Europa today.</span></p>","language":"English","publisher":"Wiley","doi":"10.1029/1998JE000628","usgsCitation":"Pappalardo, R.T., Belton, M.J., Breneman, H., Carr, M.H., Chapman, C.R., Collins, G., Denk, T., Fagents, S., Geissler, P.E., Giese, B., Greeley, R., Greenberg, R., Head, J., Helfenstein, P., Hoppa, G., Kadel, S., Klaasen, K., Klemaszewski, J.E., Magee, K., McEwen, A.S., Moore, J.M., Moore, W., Neukum, G., Phillips, C.B., Prockter, L., Schubert, G., Senske, D., Sullivan, R., Tufts, B., Turtle, E.P., Wagner, R., and Williams, K., 1999, Does Europa have a subsurface ocean?

Including saline inland seas in this total would add another 1x1012 m2. The 28 largest (area of each > 5,000 km2) freshwater lakes in the world have a total area of 1.18x1012 m2 or about 79 percent of the total area of all freshwater lakes. If the 28 large lakes bury organic carbon (OC), on average, at the same rate as Lake Michigan (5 g/m2/yr), then the annual rate of OC burial in these 28 lakes is about 6 Tg/yr (6 terragrams per year or 6x1012 g/yr; table 1). If the smaller lakes bury OC, on average, at the same rate as an average Minnesota lake (72 g/m2/yr), then the annual rate of OC accumulation in these smaller lakes is about 23 Tg/yr (23x1012 g/yr; table 1). If saline inland seas bury OC at the Lake Michigan rate, this would be an additional 5 Tg/yr, for a total of 34 Tg/yr for all freshwater lakes and saline inland seas (table 1). Mulholland and Elwood (1982) estimated the OC burial in all lakes and inland seas (excluding the Black Sea) to be 60 Tg/yr today (table 1) and an average of 20 Tg/yr for the last 10,000 years. Stallard (1998) modeled terrestrial sedimentation as a series of 864 scenarios. For lake area, he used 1.54x1012 m2, the area of the 250 largest lakes in the world. This is close to the total of large and small lakes given in table 1. Again, including inland seas to this total would add an additional 1x1012 m2. Results of scenarios for lakes and reservoirs were divided into two components, those with clastic sediments and those with organic sediments. The results of OC burial in the most likely of Stallard's scenarios for lakes range from 48 to 72 Tg/yr (table 1), the average of which is close to the 60 Tg/yr estimated by Mulholland and Elwood (1982). We will use an average of 54 Tg/yr (table 1). The closeness of these estimates, calculated by different methods, suggests that this value is not in error by more than a factor of two.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs05899","usgsCitation":"Water Resources Division, U.S. Geological Survey, 1999, Magnitude and Significance of Carbon Burial in Lakes, Reservoirs, and Northern Peatlands: U.S. Geological Survey Fact Sheet 058-99, 2 p., https://doi.org/10.3133/fs05899.","productDescription":"2 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":125663,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_058_99.jpg"},{"id":185,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/fs-0058-99/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db6494e0","contributors":{"authors":[{"text":"Water Resources Division, U.S. Geological Survey","contributorId":128075,"corporation":true,"usgs":false,"organization":"Water Resources Division, U.S. Geological Survey","id":528654,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Bloaters remained on or near bottom during the day. At night, bloaters were distributed throughout 30–65 m of water, depending on bottom depth. Shallowest depths of migration were not related to water temperature or incident light. Maximum distances of migration increased with increasing bottom depth. Nighttime midwater densities ranged from 0.00 to 6.61 fish/1,000 m</span><sup>3</sup><span>&nbsp;and decreased with increasing bottom depth. Comparisons of length distributions showed that migrating and nonmigrating bloaters did not differ in size. However, at most sites, daytime bottom catches collected a greater proportion of larger individuals compared with nighttime midwater or bottom catches. Mean target strengths by 5‐m strata indicated that migrating bloaters did not stratify by size in the water column at night. Overall, patterns in frequency of empty stomachs and mean digestive state of prey indicated that a portion of the bloater population fed in the water column at night. Bloater diet composition indicated both midwater feeding and bottom feeding. In sum, although a portion of the bloater population fed in the water column at night, bloaters were not limited to feeding at this time.

Field estimates of daily ration for age‐1–4 fish during May through October 1987 and 1988 were compared with independent predictions made by the Wisconsin energetic model and an energetic model developed by Karås and Thoresson. Predictions of daily ration using the Wisconsin model were lower than daily rations estimated from field data for all ages, primarily due to poor model–field agreement at temperatures above 22°C. This caused estimates of cumulative consumption from the Wisconsin model to be 25–50% lower than field estimates. Predictions of daily ration by the Karås–Thoresson model agreed with field estimates over a temperature range of 10–26°C for age‐1–3 yellow perch but not for older fish. Despite improvement, model predictions of cumulative consumption were 2–35% lower than field estimates. Although these tests of predicted and estimated rations may provide insight into which model produced more accurate results, it must be emphasized that field measures of daily ration are also estimates and may be in error, particularly at temperatures above 22°C where gastric evacuation rates were estimated. The Karås–Thoresson modification of the Wisconsin energetic model produced better fits to field ration data and is recommended for model applications.</span></span></p>","language":"English","publisher":"American Fisheries Society","doi":"10.1577/1548-8659(1999)128<0414:FTOTEM>2.0.CO;2","issn":"00028487","usgsCitation":"Schaeffer, J., Haas, R., Diana, J., and Breck, J., 1999, Field test of two energetic models for yellow perch: Transactions of the American Fisheries Society, v. 128, no. 3, p. 414-435, https://doi.org/10.1577/1548-8659(1999)128<0414:FTOTEM>2.0.CO;2.","productDescription":"22 p.","startPage":"414","endPage":"435","costCenters":[],"links":[{"id":501371,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/2027.42/142095","text":"External Repository"},{"id":229552,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Michigan","otherGeospatial":"Saginaw Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -83.35379911080491,\n              44.40622701769536\n            ],\n            [\n              -83.86649012999017,\n              44.02265671143746\n            ],\n            [\n              -83.96462932526535,\n              43.89022549593376\n            ],\n            [\n              -84.01587928016657,\n              43.62261147789383\n            ],\n            [\n              -83.63499279514937,\n              43.53345477307994\n            ],\n            [\n              -83.30252598374528,\n              43.83924743632402\n            ],\n            [\n              -82.90563529870151,\n              44.068965565457844\n            ],\n            [\n              -83.03751319979332,\n              44.276344901674435\n            ],\n            [\n              -83.35379911080491,\n              44.40622701769536\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"128","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0fdde4b0c8380cd53a4c","contributors":{"authors":[{"text":"Schaeffer, J.S.","contributorId":42688,"corporation":false,"usgs":true,"family":"Schaeffer","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":390652,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haas, R.C.","contributorId":94061,"corporation":false,"usgs":true,"family":"Haas","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":390654,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Diana, J.S.","contributorId":96034,"corporation":false,"usgs":true,"family":"Diana","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":390655,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Breck, J.E.","contributorId":65244,"corporation":false,"usgs":true,"family":"Breck","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":390653,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This is especially apparent in the Death Valley extended terrane, where minima in residual gravity closely correspond to well-known extensional basins, such as Owens Valley, Saline Valley, Pahrump Valley, and Death Valley itself. A three-dimensional calculation of the thickness and shape of Cenozoic deposits throughout the Basin and Range based on digital gravity, geologic, and topographic information is here interpreted in terms of the depths and shapes of extensional basins in the Death Valley region. In most basins, the gravity inversion predicts a much more complex basement than might be assumed from the surface topography. Death Valley itself is, to first order, a two-dimensional feature; as reflected by the topography of the bounding ranges down to 400–800 m below the valley floor, it is a long, narrow, and continuous valley along its entire length of 200 km. This apparent uniformity, however, belies a complex basement surface beneath the Cenozoic cover as revealed by the gravity inversion. The floor of Death Valley is pockmarked with four deep (3–5 km), steep-sided depressions that may have formed as relatively small pull-apart structures superimposed on the more uniform extension that created the twodimensional aspects of Death Valley. Lateral dimensions of these subbasins suggest a minimum of 10 km of northwest extension across Death Valley. If a regionally continuous detachment surface lies beneath Death Valley, it must lie deeper than the subbasins, that is, below a depth of 3–5 km. Similar deep, steep-sided subbasins are seen elsewhere in the Death Valley extended terrane, notably at Saline Valley, Panamint Valley, Pahrump Valley, the Amargosa Desert, and Fremont Valley, but are noticeably absent from the Mojave Desert block south of the Garlock fault zone where extensional rates are lower. The floor of the caldera complex at the southwest Nevada volcanic field is predicted by the gravity inversion to be extraordinarily deep (&gt;8 km) and rugged. Deep, linear basins that branch out of the caldera complex may reflect modification of extensional strain due to massive injections of magma into the middle and upper crust.</p>","language":"English","publisher":"GeoScienceWorld","doi":"10.1130/0-8137-2333-7.1","usgsCitation":"Blakely, R.J., Jachens, R.C., Calzia, J.P., and Langenheim, V., 1999, Cenozoic basins of the Death Valley extended terrane as reflected in regional-scale gravity anomalies : GSA Special Papers, v. 333, p. 1-16, https://doi.org/10.1130/0-8137-2333-7.1.","productDescription":"16 p.","startPage":"1","endPage":"16","costCenters":[],"links":[{"id":374407,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California, Nevada","otherGeospatial":"Death Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.894287109375,\n              35.39800594715108\n            ],\n            [\n              -115.400390625,\n              35.39800594715108\n            ],\n            [\n              -115.400390625,\n              38.08268954483802\n            ],\n            [\n              -117.894287109375,\n              38.08268954483802\n            ],\n            [\n              -117.894287109375,\n              35.39800594715108\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"333","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Blakely, Richard J. 0000-0003-1701-5236 blakely@usgs.gov","orcid":"https://orcid.org/0000-0003-1701-5236","contributorId":1540,"corporation":false,"usgs":true,"family":"Blakely","given":"Richard","email":"blakely@usgs.gov","middleInitial":"J.","affiliations":[{"id":662,"text":"Western Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":788234,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jachens, Robert C. jachens@usgs.gov","contributorId":1180,"corporation":false,"usgs":true,"family":"Jachens","given":"Robert","email":"jachens@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":788235,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Calzia, James P. jcalzia@usgs.gov","contributorId":2801,"corporation":false,"usgs":true,"family":"Calzia","given":"James","email":"jcalzia@usgs.gov","middleInitial":"P.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":788236,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Langenheim, Victoria 0000-0003-2170-5213","orcid":"https://orcid.org/0000-0003-2170-5213","contributorId":221236,"corporation":false,"usgs":true,"family":"Langenheim","given":"Victoria","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":788237,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

These pesticides are of concern because of their adverse effects on water quality and their potential adverse effects on aquatic life. Therefore, the California Regional Water Quality Control Board (CRWQCB) mandated the holding of irrigation-return water in rice fields to increase pesticide degradation and dissipation before the water is released to the Sacramento River. The CRWQCB also established performance goals to maintain drinking water quality for the city of Sacramento and to protect the habitat for aquatic life. The objectives of this study were to determine the effects of increased irrigation-return water holding times on rice pesticide concentrations and loads in the Colusa Basin Drain and the Sacramento River. Dissolved pesticide concentrations were measured in water samples collected in May through July during 1990–1993 at the Colusa Basin Drain at Road 99E near Knights Landing (Colosa Basin Drain) and at the Sacramento River at Sacramento. Pesticide concentrations and loads at both sites showed a decrease from 1990–1992 and an increase in 1993. This trend cannot be explained by the yearly holding time regulations but can be explained by the amount of yearly emergency releases. The yearly changes in pesticide concentration detected demonstrate that continued monitoring and management of pesticides is necessary to maintain water quality.</span></p>","language":"English","publisher":"Alliance of Crop, Soil, and Environmental Science Socieites","doi":"10.2134/jeq2000.00472425002900030031x","usgsCitation":"Crepeau, K.L., and Kuivila, K.M., 1999, Rice pesticide concentrations in the Colusa Basin Drain and the Sacramento River, California, 1990-1993: Journal of Environmental Quality, v. 29, no. 3, p. 926-935, https://doi.org/10.2134/jeq2000.00472425002900030031x.","productDescription":"10 p.

In the Deimos spectra, some evidence for decreased reddening toward the trailing hemisphere was found. The geometric albedoes of Phobos and Deimos were found to be 0.065 (±0.010) and 0.068 (±0.009), respectively, averaged over 440 and 600 nm, in good agreement with previous measurements. The nighttime optical depth was investigated using observations of stars. A mean value of 0.56 (±0.09) was determined from measurements at different airmass. A possible maximum in the optical depth near 0200 local time was found, which may result from condensation during the night. A measurement of the egress of Phobos from eclipse was made. Modeling of the light curve gave a scale height for the scatterers of 10–15 km. The exact time of the eclipse reappearance over the limb could be reconstructed from the measurements and was in reasonable accord with predictions, although a small modification to the predicted position of Phobos of 6.8 (±6.0) km would have produced better agreement.</span></p>","language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/98JE02555","usgsCitation":"Thomas, N., Britt, D., Herkenhoff, K.E., Murchie, S.L., Semenov, B., Keller, H., and Smith, P.H., 1999, Observations of Phobos, Deimos, and bright stars with the Imager for Mars Pathfinder: Journal of Geophysical Research E: Planets, v. 104, no.

The measured region of Phobos is expected to be a mixture of the two spectral units identified on that satellite from Phobos 2 data, and the IMP spectra of Phobos are intermediate to the two units as expected. The derived geometric albedo is consistent with the value for that part of Phobos determined from Viking imagery. The IMP spectrum of Deimos is generally consistent with previous measurements acquired from the ground and from the Hubble Space Telescope (HST), but the signal‐to‐noise ratio is lower than that of the Phobos data. The spectral contrast between the two moons is similar to that seen in HST and Phobos 2 data. Mars Pathfinder measurements therefore substantiate recent results which indicate that Phobos and Deimos are not, as previously believed, analogous to C‐type asteroids. They also provide some indications for an absorption near 700 nm, perhaps like that seen in other low‐albedo asteroids.

Minimum water surface (elevation) requirements were compared to computed water surface profiles to determine a critical low flow that would allow a navigation channel 400 feet wide and 10.5 feet deep. An upper limit on flow was established based on the flow at which open river conditions would exist for a given drawdown. The range in flows that would allow for a drawdown was used to estimate success rates using historical daily discharge data. Success rates were determined for a variety of drawdown durations between two time periods. May 1—August 15 and June 15—August 15. The greatest effect of the drawdown would he near Lock and Dam 13. Higher discharges, as well as distance from the dam. lessen the drawdown amount. Areas that would he affected by these two drawdown scenarios were predicted by overlaying maps of water surfaces with depths using a geographic information system.

The mission operated for three months and returned 2.3 Gbits of data, including over 16,500 lander and 550 rover images, 16 chemical analyses of rocks and soil, and 8.5 million individual temperature, pressure and wind measurements. Path‐finder is the best known location on Mars, having been clearly identified with respect to other features on the surface by correlating five prominent horizon features and two small craters in lander images with those in high‐resolution orbiter images and in inertial space from two‐way ranging and Doppler tracking. Tracking of the lander has fixed the spin pole of Mars, determined the precession rate since Viking 20 years ago, and indicates a polar moment of inertia, which constrains a central metallic core to be between 1300 and ∼2000 km in radius. Dark rocks appear to be high in silica and geochemically similar to anorogenic andesites; lighter rocks are richer in sulfur and lower in silica, consistent with being coated with various amounts of dust. Rover and lander images show rocks with a variety of morphologies, fabrics and textures, suggesting a variety of rock types are present. Rounded pebbles and cobbles on the surface as well as rounded bumps and pits on some rocks indicate these rocks may be conglomerates (although other explanations are also possible), which almost definitely require liquid water to form and a warmer and wetter past. Air‐borne dust is composed of composite silicate particles with a small fraction of a highly magnetic mineral, interpreted to be most likely maghemite; explanations suggest iron was dissolved from crustal materials during an active hydrologic cycle with maghemite freeze dried onto silicate dust grains. Remote sensing data at a scale of a kilometer or greater and an Earth analog correctly predicted a rocky plain safe for landing and roving with a variety of rocks deposited by catstrophic floods, which are relatively dust free. The surface appears to have changed little since it formed billions of years ago, with the exception that eolian activity may have deflated the surface by ∼3–7 cm, sculpted wind tails, collected sand into dunes, and eroded ventifacts (fluted and grooved rocks). Pathfinder found a dusty lower atmosphere, early morning water ice clouds, and morning near‐surface air temperatures that changed abruptly with time and height. Small scale vortices, interpreted to be dust devils, were observed repeatedly in the afternoon by the meteorology instruments and have been imaged.</span></p>","language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/98JE02554","usgsCitation":"Golombek, M.P., Anderson, R.C., Barnes, J., Bell, J.F., Bridges, N.T., Britt, D., Bruckner, J., Cook, R.A., Crisp, D., Crisp, J., Economou, T., Folkner, W.M., Greeley, R., Haberle, R., Hargraves, R., Harris, J., Haldemann, A.F., Herkenhoff, K.E., Hviid, S., Jaumann, R., Johnson, J.R., Kallemeyn, P.H., Keller, H., Kirk, R.L., Knudsen, J.M., Larsen, S., Lemmon, M.T., Madsen, M., Magalhaes, J., Maki, J., Malin, M., Manning, R.M., Matijevic, J., McSween, H., Moore, H., Murchie, S., Murphy, J., Parker, T.J., Rieder, R., Rivellini, T., Schofield, J.T., Seiff, A., Singer, R., Smith, P.H., Soderblom, L.A., Spencer, D., Stoker, C.R., Sullivan, R., Thomas, N., Thurman, S., Tomasko, M., Vaughan, R.M., Wänke, H., Ward, A.W., and Wilson, G., 1999, Overview of the Mars Pathfinder Mission: Launch through landing, surface operations, data sets, and science results: Journal of Geophysical Research E: Planets, v. 104, no.

This report describes the environmental characteristics and water quality at 16 benchmark basins in the Eastern United States. In most of the basins, stream-water chemistry seems to be controlled by the interaction of acidic precipitation with the underlying soils and bedrock.
