To help assess the value of using such models to make predictions, a postaudit was conducted on a previously studied area in the Salt River and lower Santa Cruz River basins in central Arizona. A deterministic, distributed-parameter model of the ground-water system in these alluvial basins was calibrated by Anderson (1968) using about 40 years of data (1923–64). The calibrated model was then used to predict future water-level changes during the next 10 years (1965–74). Examination of actual water-level changes in 77 wells from 1965–74 indicates a poor correlation between observed and predicted water-level changes. The differences have a mean of 73 ft that is, predicted declines consistently exceeded those observed and a standard deviation of 47 ft. The bias in the predicted water-level change can be accounted for by the large error in the assumed total pumpage during the prediction period. However, the spatial distribution of errors in predicted water-level change does not correlate with the spatial distribution of errors in pumpage. Consequently, the lack of precision probably is not related only to errors in assumed pumpage, but may indicate the presence of other sources of error in the model, such as the two-dimensional representation of a three-dimensional problem or the lack of consideration of land-subsidence processes. This type of postaudit is a valuable method of verifying a model, and an evaluation of predictive errors can provide an increased understanding of the system and aid in assessing the value of undertaking development of a revised model.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.1986.tb00993.x","usgsCitation":"Konikow, L.F., 1986, Predictive accuracy of a ground-water model--Lessons from a postaudit: Groundwater, v. 24, no. 2, p. 173-184, https://doi.org/10.1111/j.1745-6584.1986.tb00993.x.","productDescription":"12 p.

No significant strain accumulation was detected in the Shumagin gap, but experience at similar subduction zones and simple models of the subduction process suggest that a measurable amount of strain should have accumulated. The most likely explanation of the observation is that subduction mere is either aseismic or episodic. The strain accumulation measured in the Yakataga gap is consistent with that expected for the plate convergence rate, although the direction of maximum compression may suggest a somewhat more oblique convergence than expected.","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.231.4738.585","issn":"00368075","usgsCitation":"Savage, J., Lisowski, M., and Prescott, W., 1986, Strain accumulation in the Shumagin and Yakataga seismic gaps, Alaska: Science, v. 231, no. 4738, p. 585-587, https://doi.org/10.1126/science.231.4738.585.","productDescription":"3 p.","startPage":"585","endPage":"587","costCenters":[],"links":[{"id":226160,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Alaska-Aleutian arc","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -189.10965580376075,\n              54.0918062192018\n            ],\n            [\n              -188.46998511535634,\n              51.42158520362793\n            ],\n            [\n              -180.51845149404588,\n              50.88545679504214\n            ],\n            [\n              -171.68033845898537,\n              51.398431819201264\n            ],\n            [\n              -155.36031661418076,\n              55.42197880703884\n            ],\n            [\n              -156.56256480877937,\n              58.55012529437823\n            ],\n            [\n              -174.27020316925132,\n              53.601097458724624\n            ],\n            [\n              -181.85788848341838,\n              53.27528445354847\n            ],\n            [\n              -189.10965580376075,\n              54.0918062192018\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"231","issue":"4738","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9895e4b08c986b31c0b1","contributors":{"authors":[{"text":"Savage, J.C. 0000-0002-5114-7673","orcid":"https://orcid.org/0000-0002-5114-7673","contributorId":102876,"corporation":false,"usgs":true,"family":"Savage","given":"J.C.","affiliations":[],"preferred":false,"id":368494,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lisowski, M.","contributorId":70381,"corporation":false,"usgs":true,"family":"Lisowski","given":"M.","email":"","affiliations":[],"preferred":false,"id":368492,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Prescott, W.H.","contributorId":96337,"corporation":false,"usgs":true,"family":"Prescott","given":"W.H.","email":"","affiliations":[],"preferred":false,"id":368493,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

One of the principal objectives of the leg was to drill and sample a thick oceanward-dipping wedge of seismic reflectors, known to characterize much of the multichannel seismic (MCS) profile data recorded across ocean-continent transitions in the NE Atlantic north of 55°N. Elsewhere, these reflectors have previously been the target of deep drilling during Legs 48 and 81 of the International Phase of Ocean Drilling IPOD (Montadert, Roberts et al. 1979; Roberts, Schnitker et al. 1984). These efforts met with some success, sampling only the uppermost part of the sequence and identifying a series of tholeiitic lava flows. Over the Outer V~ring Plateau, a number of MCS profiles reveal a distinct change in seismic character at the base of the well-stratified dipping reflector sequence, where an irregular surface characterized by a band of low-frequency, high-amplitude reflectors occurs.

We have analyzed the organic matter in pairs of laminated/bioturbated interbeds from Cretaceous and Devonian rocks deposited in epicontinental and oceanic settings for the purpose of studying the influence of depositional and early diagenetic environment on the organic geochemical properties of marine shales. Results of these analyses indicate that for rocks that are still in a diagenetic stage of thermal alteration, the relative abundance of biomarker compounds and specific biomarker indices can be useful indicators of depositional and early diagenetic conditions. Pristane/phytane ratios are generally highest for laminated rocks from epicontinental basins and appear to reflect the input of isoprenoid precursors more than oxygenated versus anoxic depositional conditions. The thermally immature laminated rocks are characterized by relatively high contents of 17β(H), 21β(H)-hopanes, hopenes, sterenes and diasterenes, and by strong predominance of the 22R over 22S homohopane isomers. Thermally immature bioturbated samples are characterized by absence of the β,β-hopanes, by low contents of both saturated and unsaturated polycyclic hydrocarbons, and by slight or no predominance of the 22R over 22S homohopane isomers. There are less obvious compositional differences between the saturated hydrocarbons in the laminated and bioturbated units from the thermally mature sequences. For both the thermally mature and immature laminated samples, the degree of isomerization at the&nbsp;</span><sup>22</sup><span>C position for hopanes and at the&nbsp;</span><sup>20</sup><span>C position for steranes is generally consistent with the degree of thermal maturity interpreted from other properties of the organic matter.

Extensive wildlife sampling in 1983 confirmed that DDE, the major metabolite of the insecticide DDT, was present at high concentrations in wildlife at selected sites in the Rio Grande and Pecos River drainages. DDE in carcasses ranged up to 47 ppm (wet weight) in western kingbirds (<i>Tyrannus verticalis</i>), 35 ppm in house sparrows (<i>Passer domesticus</i>), 46 ppm in Brazilian free-tailed bats (<i>Tadarida brasiliensis</i>), and 104 ppm in whiptail lizards (<i>Cnemidophorus</i><span>&nbsp;</span>spp.). DDE was also detected in gut contents from western kingbirds at some of the highest concentrations ever reported, ranging up to 21 ppm in proventricular samples. An average of 40% of the eggs of black-crowned night-herons (<i>Nycticorax nycticorax</i>) from two sites along the Pecos River in New Mexico had DDE levels (≥8 ppm) that have been associated in other studies with impaired reproduction. In contrast, wintering mallards (<i>Anas platyrhynchos</i>) and American coots (<i>Fulica americana</i>) from the study area did not accumulate elevated DDE levels. DDE in wildlife samples at control sites (nonagricultural areas) was either absent or averaged less than 0.35 ppm.</p><p>Collectively, these data provide evidence that there is major DDE contamination of several vertebrate species in portions of the Rio Grande and Pecos River drainages, but whether the contamination is recent or residual was not determined. Apparently, the source was not DDE contamination present in dicofol (4-chloro-<i>a</i>-(4-chlorophenyl)-<i>a</i>-(trichloromethyl) benzenemethanol); neither dicofol nor its metabolite,<i>p,p'</i>-dichlorobenzophenone, were detected in wildlife carcasses (0.1 ppm detection limit) or proventricular contents (0.01 ppm detection limit) of western

Both bird species had a high (95–100%) incidence of Lepidoptera, mostly pale western cutworms,&nbsp;</span><i>Agrotis orthogonia</i><span>&nbsp;Morrison, in their stomachs at 3 days postspray. Incidence of cutworms and other insects in stomachs of birds from sprayed fields was lower at 9 and 16 days postspray than in control birds, presumably due to insecticide-caused reduction of insects. Effects of birds on population dynamics of insect pests in wheat are unknown, but birds do contribute to cutworm mortality. Predation is one of the limiting factors to cutworm increase and can supplement insecticidal control. Brain cholinesterase activity in horned larks collected from the sprayed fields at 3 and 9 days postspray was significantly lower than in unexposed larks, but at 16 days the difference was not significant. Although nontarget birds clearly were exposed to chlorpyrifos and manifested a sublethal physiological response, toxic effects were lesssevere than those resulting from endrin application for cutworm control in wheat. More study is needed of larger chlorpyrifos-treated fields under a variety of conditions to fully assess effects on nontarget life.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/ee/15.1.147","usgsCitation":"McEwen, L.C., DeWeese, L.R., and Schladweiler, P., 1986, Bird predation on cutworms (Lepidoptera: Noctuidae) in wheat fields and chlorpyrifos effects on brain cholinesterase activity: Environmental Entomology, v. 15, no. 1, p. 147-151, https://doi.org/10.1093/ee/15.1.147.","productDescription":"5 p.","startPage":"147","endPage":"151","numberOfPages":"5","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193864,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.er.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"1","noUsgsAuthors":false,"publicationDate":"1986-02-01","publicationStatus":"PW","scienceBaseUri":"4f4e4a2be4b07f02db612f65","contributors":{"authors":[{"text":"McEwen, L.

Slope analysis is facilitated by examining the average slope in 250‐m altitude‐depth intervals both globally and in each of eight tectonic plates. The most striking feature of the map is the multiple parallel bands of steep slope at subduction zones. Submarine volcanic chains produce zones of steep slope that show little degradation at the scale of the map since the Cretaceous. The average slope, or roughness, of spreading ridges decreases exponentially with increasing spreading rate. The passive continental margins generate a steep zone at 1–2 km depth. The lowest average global slope (0.2°) occurs at sea level and reflects the base level that the sea provides for subaerial erosion and the upper limit for marine sedimentation. Slope minima also are caused by the abyssal plains at 4–6 km depth and by glacial ice caps at 3 km elevation.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/EO067i048p01353-01","usgsCitation":"Moore, J.G., and Mark, R.K., 1986, World slope map: Eos, Transactions, American Geophysical Union, v. 67, no. 48, p. 1353-1362, https://doi.org/10.1029/EO067i048p01353-01.","productDescription":"10 p.","startPage":"1353","endPage":"1362","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":371361,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"67","issue":"48","noUsgsAuthors":false,"publicationDate":"2011-06-03","publicationStatus":"PW","contributors":{"authors":[{"text":"Moore, James G. 0000-0002-7543-2401 jmoore@usgs.gov","orcid":"https://orcid.org/0000-0002-7543-2401","contributorId":2892,"corporation":false,"usgs":true,"family":"Moore","given":"James","email":"jmoore@usgs.gov","middleInitial":"G.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":779705,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mark, R.

Core from a 181-m-deep hole extending 123 m below sea level shows the results of 12 yr of hydrothermal alteration of basaltic tephra. The primary cause of heating of the tephra and of development of the hydrothermal system was the intrusion of dikes below sea level. At present, the hottest part of the hole, at a maximum temperature of 150 °C, is cooling at ∼0.9 °C per year. Palagonitization of sideromelane glass, a dominant constituent of the tephra, is an important alteration process that is strongly temperature dependent, the rate doubling for every 12 °C increase. At 60 °C, &lt;40% of the glass is palagonitized, but above 100 °C, &gt;90% is palagonitized. Above 120 °C, olivine crystals are replaced on their edges by nontronite; the thickness of clay doubles for each 8 °C increase. Ten hydrothermal minerals have crystallized in the tephra at 25 to 150 °C; the dominant species are smectite (nontronite), analcite, phillipsite, and tobermorite. The primary clay species of palagonite is probably nontronite. Other minerals are halite, opal, calcite, chabazite, xonotlite, anhydrite, and gypsum. No major differences in mineral occurrence are noted above and below sea level, but phillipsite and tobermorite tend to grow larger below sea level, even at the same temperature. Analcite appears at lower temperature (55 °C) above sea level than below sea level (75 °C). Anhydrite is most abundant deep in the hole, where inflowing, cool sea water precipitated sulfate due to reduced sulfate solubility at higher temperatures.</span></p>","language":"English","publisher":"GSA","doi":"10.1130/0016-7606(1986)97<648:HMAARA>2.0.CO;2","usgsCitation":"Jakobsson, S.P., and Moore, J.G., 1986, Hydrothermal minerals and alteration rates at Surtsey volcano, Iceland: GSA Bulletin, v. 97, no. 5, p. 648-659, https://doi.org/10.1130/0016-7606(1986)97<648:HMAARA>2.0.CO;2.","productDescription":"12 p.","startPage":"648","endPage":"659","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":371360,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Iceland","otherGeospatial":"Surtsey","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -21.654052734375,\n              62.67918619685372\n            ],\n            [\n              -19.248046875,\n              62.67918619685372\n            ],\n            [\n              -19.248046875,\n              63.68524808030715\n            ],\n            [\n              -21.654052734375,\n              63.68524808030715\n            ],\n            [\n              -21.654052734375,\n              62.67918619685372\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"97","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Jakobsson, S.

The style of creep poleward of ± 30° varies with latitude, possibly due to variations in ice rheology with temperature.
