This paper investigates the relative efficiency of GN and three conjugate-direction parameter-estimation methods on two-dimensional, steady-state and transient ground-water flow test cases. The steady-state test cases are included to compare the performance of the algorithm with published examples. The three conjugate-direction methods are the Fletcher-Reeves (FR) and quasi-Newton (QN) regression methods, and combination Fletcher-Reeves quasi-Newton (FR-QN). All three are combined with Newton's method of calculating step size. The numerical ground-water flow model is described by McDonald and Harbaugh.","largerWorkTitle":"Computational Methods in Subsurface Hydrology","conferenceTitle":"Proceedings of the 8th International Conference on Computational Methods in Water Resources","conferenceDate":"11 June 1990 through 15 June 1990","conferenceLocation":"Venice, Italy","language":"English","publisher":"Publ by Springer-Verlag Berlin","publisherLocation":"Berlin 33, Germany","isbn":"038752701X","usgsCitation":"Hill, M.C., 1990, Relative efficiency of four parameter-estimation methods in steady-state and transient ground-water flow models, <i>in</i> Computational Methods in Subsurface Hydrology, Venice, Italy, 11 June 1990 through 15 June 1990, p. 103-108.","startPage":"103","endPage":"108","numberOfPages":"6","costCenters":[],"links":[{"id":222927,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa681e4b0c8380cd84ebe","contributors":{"editors":[{"text":"Gambolati G.Rinaldo A.Brebbia C.A.Gray W.G.Pinder G.F.","contributorId":128422,"corporation":true,"usgs":false,"organization":"Gambolati G.Rinaldo A.Brebbia C.A.Gray W.G.Pinder G.F.","id":536314,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Hill, M.

Total organic carbon contents (Corg) are commonly greater than 10 wt %. Porphyrin concentrations (vanadyl + nickel) are as high as 40000 ppm relative to extractable bitumen. In bulk, the organic matter contained in the shales is mostly type II and III (Rock-Eval hydrogen indexes 200-400 mg of hydrocarbons/g of Corg). The finding of high porphyrin concentrations in type III organic matter is unusual but can be explained by a depositional model wherein high preservation of primary organic production (water column photosynthesis) is combined with substantial input of allochthonous organic matter. The allochthonous organic matter (low porphyrin concentration) may come from erosion during advance of the sea across the area or from fluvial transport from shore.","language":"English","publisher":"American Chemical Society","doi":"10.1021/ef00024a004","issn":"08870624","usgsCitation":"Clayton, J., and Michael, G., 1990, Controls on porphyrin concentrations of Pennsylvanian organic-rich shales, Western U.S.A.: Energy & Fuels, v. 4, no. 6, p. 644-646, https://doi.org/10.1021/ef00024a004.","productDescription":"3 p.","startPage":"644","endPage":"646","numberOfPages":"3","costCenters":[],"links":[{"id":223487,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","issue":"6","noUsgsAuthors":false,"publicationDate":"2002-05-01","publicationStatus":"PW","scienceBaseUri":"5059fbd2e4b0c8380cd4dfac","contributors":{"authors":[{"text":"Clayton, J.L.","contributorId":76767,"corporation":false,"usgs":true,"family":"Clayton","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":371980,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Michael, G.E.","contributorId":63456,"corporation":false,"usgs":true,"family":"Michael","given":"G.E.","email":"","affiliations":[],"preferred":false,"id":371979,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Selected tissues were collected for microbiological, parasitological, toxicological or histopathological examinations. Dehydration was the most common cause of death. Lead poisoning, trauma, emaciation (starvation) and trombidiosis were other causes of death; nonfatal nocardiosis and avian pox also were present. There was no evidence that ingested plastic caused mechanical lesions or mortality in 1987, but most of the chicks had considerably less plastic in them than chicks from earlier years. Human activity (lead poisoning and vehicular trauma) caused mortality at Midway Atoll and represented additive mortality for pre-fledgling albatrosses.</p>","language":"English","publisher":"Wildlife

This system eroded both a major subaerial canyon cutting the margin southeastward from the present Ebro Delta and an axial valley that drained northeastward down Valencia Trough. Post-Messinian submergence of this topography and the Pliocene regime of high sea levels resulted in a marine hemipelagic drape over the margin. Late Pliocene to Pleistocene glacial climatic cycles, drainagebasin deforestation, and sea-level lowstands combined to increase sediment supply, cause the margin to prograde, and create a regime of lowstand sediment-gravity flows in the deeper margin. The depositional patterns of regressive, transgressive and highstand sea-level regimes suggest that location of the sediment source near the present Ebro Delta throughout the late Cenozoic, southward current advection of sediment, and greater subsidence in the southern margin combined to cause generally asymmetric progradation of the margin to the southeast. Thicker, less stable deposits filling the Messinian subaerial canyon underwent multiple retrograde failures, eroded wide gullied canyons and formed unchanneled base-of-slope sediment aprons in the central margin area; other margin areas to the north and south developed a series of channel-levee complexes.</div><div class=\"u-margin-s-bottom\">On the basin floor, the formation of Valencia Valley over the Messinian subaerial valley and earlier faults led to draining of about 20% of the Ebro Pleistocene sediment from channel-levee complexes through the valley to prograde Valencia Fan as much as 500 km northeast of the margin. Thus, the Ebro margin has two growth directions, mainly southeastward during higher sea levels, and eastward to northeastward during lower sea levels. The northeastward draining of turbidity currents has produced unusually thin and widely dispersed turbidite systems compared to those on ponded basin floors.</div><div class=\"u-margin-s-bottom\">During the past few centuries, man's impact has exceeded natural controls on Ebro margin growth. Deforestation of the drainage basin more than doubled the normal Holocene sediment supply, and construction of dams then reduced the supply by 95%. This reduction of the past 50 years has caused erosion of the delta and contamination of bottom sediment because normal Holocene sediment discharge is not available to prograde the delta or help dilute pollutants.</div></div></div></div></div><div id=\"preview-section-introduction\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(90)90127-6","issn":"00253227","usgsCitation":"Nelson, C., and Maldonado, A., 1990, Factors controlling late Cenozoic continental margin growth from the Ebro Delta to the western Mediterranean deep sea: Marine Geology, v. 95, no. 3-4, p. 419-440, https://doi.org/10.1016/0025-3227(90)90127-6.","productDescription":"22 p.","startPage":"419","endPage":"440","numberOfPages":"22","costCenters":[],"links":[{"id":223387,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"95","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0eb8e4b0c8380cd535b4","contributors":{"authors":[{"text":"Nelson, C.H.","contributorId":88346,"corporation":false,"usgs":true,"family":"Nelson","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":371966,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Maldonado, A.","contributorId":90437,"corporation":false,"usgs":true,"family":"Maldonado","given":"A.","affiliations":[],"preferred":false,"id":371967,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The finite-difference model numerically integrates equations of mass and momentum conservation in conjunction with a transport equation for heat, salt, and constituent fluxes. Lateral and longitudinal density gradients are determined from salinity distributions computed from the convection-diffusion equation and an equation of state that expresses density as a function of temperature and salinity; thus, the hydrodynamic and transport computations are directly coupled. Horizontal density variations are shown to contribute significantly to momentum fluxes determined in the hydrodynamic computation. These fluxes lead to enchanced tidal pumping, and consequently greater dispersion, as is evidenced by numerical simulations. Density gradient effects on tidal propagation and transport behavior are discussed and demonstrated.","largerWorkTitle":"Hydraulic Engineering - Proceedings of the 1990 National Conference","conferenceTitle":"Hydraulic Engineering - Proceedings of the 1990 National Conference","conferenceDate":"30 July 1990 through 31 July 1990","conferenceLocation":"San Diego, CA, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"Boston, MA, United States","isbn":"0872627748","usgsCitation":"Schaffranek, R.W., and Baltzer, R.A., 1990, Horizontal density-gradient effects on simulation of flow and transport in the Potomac Estuary, <i>in</i> Hydraulic Engineering - Proceedings of the 1990 National Conference, San Diego, CA, USA, 30 July 1990 through 31 July 1990, p. 1251-1256.","startPage":"1251","endPage":"1256","numberOfPages":"6","costCenters":[],"links":[{"id":223542,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a321be4b0c8380cd5e51d","contributors":{"editors":[{"text":"Chang Howard H.Hill Joseph C.","contributorId":128375,"corporation":true,"usgs":false,"organization":"Chang Howard H.Hill Joseph C.","id":536317,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Schaffranek, Raymond W.","contributorId":86314,"corporation":false,"usgs":true,"family":"Schaffranek","given":"Raymond","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":372121,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baltzer, Robert A.","contributorId":34269,"corporation":false,"usgs":true,"family":"Baltzer","given":"Robert","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":372120,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Mortality of eggs and young, caused primarily by avian predators, accounted for most of the annual variation in productivity. Failure to produce eggs, clutch size variation, and the hatchability of eggs were generally less important. The stage of breeding at which annual productivity was most strongly regulated differed among species. In murres, chick-rearing success accounted for the largest share of annual variation in overall productivity, whereas incubation success was the key factor in fulmars, kittiwakes, and puffins. Although avian predators were the dominant proximate cause of egg and chick losses in some species, food supply seemed ultimately responsible for variation in all the major components of productivity. Concordance of productivity among species was low for the marine bird community as a whole, but selected pairs of species exhibited a greater tendency for high and low productivities to occur in the same years. Compared with the same or similar species outside Alaska, Semidi Islands birds were in one of three categories: (</span><i>i</i><span>) species whose productivity was about the same as reported from other areas (fulmars and gulls), (</span><i>ii</i><span>) species with comparatively low productivity (murres, puffins, kittiwakes), and (</span><i>iii</i><span>) species with similar mean productivity but greater annual variation (cormorants).

Distributions of laying or hatching observed in 11 species during 1–7 years are presented; less detailed information is available on the breeding schedules of three species. The combined laying period of 14 species lasted 3 months from mid-April to mid-July; the first eggs of the earliest and latest species were laid about 9 weeks apart. Mean laying dates varied by 2–16 days in nine species observed in 2 or more years. Although the egg-laying sequence of species was largely preserved from year to year, we found little evidence of concordant annual variation in breeding seasons. Species that fed lower in the food chain tended to breed earlier than those that fed at higher trophic levels. Early laying was correlated with longer laying periods, both within and between species. With the exception of three puffin species, birds with similar food habits exhibited less overlap in hatching and fledging dates than laying dates. A test for nonrandom dispersion of breeding times failed to find evidence for competitive avoidance of breeding overlap in piscivores or planktivores. Species may not have timed their egg laying to provide for maximum food availability during chick rearing. Rather, the comparative analysis of breeding schedules suggests that breeding times were determined more by the food requirements of laying females. Young females laying relatively late probably account for the right-skewed distributions of egg laying observed in this and other studies of colonial seabirds.</span></p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/z90-247","usgsCitation":"Hatch, S.A., and Hatch, M.A., 1990, Breeding seasons of oceanic birds in a subarctic colony: Canadian Journal of Zoology, v. 68, no. 8, p. 1664-1679, https://doi.org/10.1139/z90-247.","productDescription":"16 p.","startPage":"1664","endPage":"1679","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":335371,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Gulf of Alaska, Semidi Islands","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -157.00836181640625,\n              55.91535151540654\n            ],\n            [\n              -156.4617919921875,\n              55.91535151540654\n            ],\n            [\n              -156.4617919921875,\n              56.315013425566924\n            ],\n            [\n              -157.00836181640625,\n              56.315013425566924\n            ],\n            [\n              -157.00836181640625,\n              55.91535151540654\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"68","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a4254ae4b0c825128ad4d5","contributors":{"authors":[{"text":"Hatch, Scott A. 0000-0002-0064-8187 shatch@usgs.gov","orcid":"https://orcid.org/0000-0002-0064-8187","contributorId":2625,"corporation":false,"usgs":true,"family":"Hatch","given":"Scott","email":"shatch@usgs.gov","middleInitial":"A.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":668698,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hatch, Martha A.","contributorId":181576,"corporation":false,"usgs":false,"family":"Hatch","given":"Martha","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":668699,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The first technique regressed survival of nests or eggs during a time interval against interval length. Departure of the y-intercept from 1.0 estimated the short-term effect of the visit at the beginning of the interval. The y-intercepts (±95% CI) for whole nests and eggs during the egg laying period were 1.11 ± 0.31 and 1.06 ± 0.31, respectively. During incubation the same 2 parameters were 0.66 ± 0.31 and 0.66 ± 0.33. The regression method was, thus, imprecise and failed to discriminate among widely varying potential impacts of visitors. The second method involved visiting nests and then immediately revisiting them after pairs had returned to their territories. This method estimated loss of eggs as a result of displacement of territorial pairs during the first visit. Only 1 of 50 eggs was lost (n = 27 nests) as a result of visits during egg laying, whereas no eggs were lost (n = 225 eggs and 55 nests) owing to visits during the incubation period. I conclude that the regression approach is an imprecise tool for estimating visitor impact, but results from both methods indicate little effect of nest visitation under conditions existing on the colony I studied.</span></p>","language":"English","publisher":"Wiley","doi":"10.2307/3809655","usgsCitation":"Sedinger, J.S., 1990, Effects of visiting black brant nests on egg and nest survival: Journal of Wildlife Management, v. 54, no. 3, p. 437-443, https://doi.org/10.2307/3809655.","productDescription":"7 p.","startPage":"437","endPage":"443","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":336896,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Tutakoke River, Yukon-Kuskokwim Delta","volume":"54","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58be8341e4b014cc3a3a9a2d","contributors":{"authors":[{"text":"Sedinger, James S.","contributorId":84861,"corporation":false,"usgs":false,"family":"Sedinger","given":"James","email":"","middleInitial":"S.","affiliations":[{"id":12742,"text":"University of Nevada Reno","active":true,"usgs":false}],"preferred":false,"id":680845,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The fish were stocked into Lake Huron in the spring. Otolith marks consisted of groups of daily growth rings accentuated into recognizable patterns by steadily raising and lowering the temperature about IOA?C (from a base of 1-4A?C) over 14h. In 1987, groups of marked and control fish were held for 6 months. The otoliths were removed from samples of the fish, embedded in epoxy, thin-sectioned by grinding in the sagittal plane, etched, and viewed by using a combination of a compound microscope (400-1000x) and a video enhancement system. One or more readable otolith sections were obtained from 39 of a sample of 40 fish. Three independent readers examined 41 otoliths for marks and correctly classified the otoliths, with accuracies of 85, 98,and 100%, as being from marked or unmarked fish. The exact number of rings in a recognizable pattern sometimes differed from the number of temperature cycles to which the fish were exposed. Counts of daily rings within groups of six rings varied less than counts within groups of three rings.\r\n","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Fish-marking techniques","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"American Fisheries Society","publisherLocation":"Bethesda, MD","usgsCitation":"Bergstedt, R., Eshenroder, R., Bowen, C., Seelye, J., and Locke, J., 1990, Mass-marking of otoliths of lake trout sac fry by temperature manipulation, chap. <i>of</i> Fish-marking techniques, 216-223.","productDescription":"216-223","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":128568,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a19e4b07f02db605a9c","contributors":{"editors":[{"text":"Parker, N.

By the early 1970s, lake trout abundance increased sharply and remained at a high level. This rapid recovery resulted from several strong year classes produced by the small spawning aggregations that reached maturity in the 1960s.
