Intrusive and stratigraphic relationships and new potassium-argon dating indicate episodic magmatism from about 30 Ma to the present. Additional stratigraphic and radiometric evidence suggests that limited rift-related magmatism began as early as about 50 Ma. An early phase of crustal extension in the region was accompanied by faulting and graben formation and by dike-swarm intrusion. The style of extension and intrusion changed at ∼20 Ma. Localized volcanism and sheeted dike injection ceased and were replaced by the intrusion of thick gabbro dikes. This change may mark the onset of sea-floor spreading in the central Red Sea.</p><p>The dikes and volcanic rocks consist of a bimodal mafic-felsic suite with transitional subalkaline to alkaline chemistry. Although no unique petrogenetic model can be developed for the suite, the following observations and conclusions have been drawn from the available reconnaissance geochemistry: (1) strontium isotopic initial ratios overlap in the range 0.7031 to 0.7047 and are not clearly related to alkalinity or silica content. The bimodality and alkalinity of the suite are therefore not products of contamination by the radiogenic Precambrian upper-crustal granitic rocks exposed in the region. (2) Several of the evolved rocks (rhyolites and comendite) show large to extreme negative europium anomalies and heavy rare-earth–element (HREE) enrichment, features that cannot be explained by low-pressure crystal fractionation of potential parent magmas. An intriguing possibility is that HREE enrichments and large negative Eu anomalies of some peraluminous rhyolites (and granites) may result from the complete melting of garnet from middle or lower crustal rocks. (3) Most of the basalts are light rare-earth element (LREE) enriched, consistent with derivation from fertile mantle in a continental-rift setting; however, interaction of the mafic melts with lower continental crust cannot be ruled out.</p><p>A model of poly-baric mantle-melt derivation, producing several alkaline-subalkaline cycles, best explains magmatism in the Red Sea region. Differences in the depths and dynamics of mantle-melt extraction and transport brought about through changes in crust and mantle structure as the rift and paar developed may account for the transition from mixed alkaline-subalkaline bimodal magmatism of the pre-20 Ma rift basin to exclusively subalkaline (tholeiitic) magmatism at the Red Sea spreading axis and to predominantly alkali basalt volcanism inland (within the Arabian Shield).</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1987)98<400:MHORSR>2.0.CO;2","usgsCitation":"Pallister, J., 1987, Magmatic history of Red Sea rifting: Perspective from the central Saudi Arabian coastal plain: Geological Society of America Bulletin, v. 98, no. 4, p. 400-417, https://doi.org/10.1130/0016-7606(1987)98<400:MHORSR>2.0.CO;2.","productDescription":"18 p.","startPage":"400","endPage":"417","numberOfPages":"18","costCenters":[],"links":[{"id":225848,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"98","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4b46e4b0c8380cd69407","contributors":{"authors":[{"text":"Pallister, J.S.","contributorId":46534,"corporation":false,"usgs":true,"family":"Pallister","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":369127,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The model was calibrated using data from both horizontal and inclined pyranometers at six sites over four years. Values for the Ångstrom turbidity coefficient and the percentage of circumsolar diffuse radiation were determined using an iterative best fit technique.

These formations are eastward-dipping sedimentary rock that rest on Precambrian crystalline rock and are overlain by Pleistocene deposits. The units that are the principal sources of ground water were grouped into three aquifers (upper, St. Peter, and Elk Mound), and the less permeable units are grouped into three confining units (Maquoketa-Sinnipee, St. Lawrence, and Precambrian). The geologic and hydraulic characteristics of the aquifers and confining units are estimated from logs of more than 1,000 Brown County wells, from results of a packer test, and from published values.</p>\n<p>Recharge to the water table, which was estimated at five monitored sites, ranges from 1 to 6 inches a year; most recharge is contributed by spring snowmelt and rainfall. A cone of depression caused by pumping the deeper aquifers in the Green Bay metropolitan area induces flow from the upper aquifer to the underlying st. Peter aquifer throughout most of the county. Several reaches of Duck Creek and the Suamico River also contribute water to the aquifers. A</p>\n<p>bout 13 million gallons per day of ground water was pumped in Brown County during 1979, 63 percent of which was from wells open to both the St. Peter and Elk Mound aquifers.

However, water from wells sampled in an area between the Fox River and Silurian escarpment have elevated levels of sodium (44 milligrams per liter) and sulfate (226 milligrams per liter).

Model results indicate that sources of ground water pumped from wells tapping the St. Peter and Elk Mound aquifers in Brown County, 1979, include 4.8 million gallons per day of underflow, most of which enters the county across the west border; 1.9 million gallons per day of flow from vertical leakage within the county; and 1.5 million gallons per day from storage. The model is most sensitive to the horizontal hydraulic conductivity of the upper aquifer. Vertical hydraulic conductivity of the confining units and recharge rates to the water-table aquifer are the least well-defined model parameters.</p>","language":"English","publisher":"Wisconsin

Most water in the basin is derived from precipitation, which averages 48 inches (366 billion gallons) per year. An additional 67 billion gallons of water per year enters the basin from Massachusetts in the West Branch of the Farmington River, Hubbard River, Valley Brook and some smaller streams. Of the total 433 billion gallons, 174 billion gallons returns to the atmosphere through evaporation and transpiration. 239 billion gallons flows out of the study area in the Farmington River at Tariffville, and 20 billion gallons is diverted for Hartford water supply. Variations in streamflow at 23 continuous-record gaging stations are summarized in standardized graphs and tables that can be used to estimate streamflow characteristics at other sites. For example, mean flow and low-flow characteristics such as the 7-day annual minimum flow for 2-year and 10-year recurrence intervals, have been determined for many partial-record stations from the data for the 23 continuous-record stations. Of the 31 principal lakes, ponds, and reservoirs in the basin, eight have usable storage capacities of more than 1 billion gallons. Two of the largest, Colebrook River Lake and Barkhamsted Reservoir, have more than 30 billion gallons usable storage. Floods have occurred in the area in every month of the year. The greatest known flood on the Farmington River was in August 1955, which had a peak flow of 140,000 cubic feet per second at Collinsville. Since then, three major floodcontrol reservoirs have been constructed to reduce the hazards of high streamflow. The major aquifers underlying the basin are composed of unconsolidated materials (stratified drift and till) and bedrock (sedimentary, igneous, and metamorphic). Stratified drift overlies till and bedrock in valleys and lowlands; it averages about 90 feet in thickness, and is capable of large sustained yields of water to individual wells. Based on hydrologic characteristics and available recharge, sixteen stratified-drift areas are selected as the most favorable for large-scale development. Potential yields can be estimated by several methods. Small water supplies can be obtained from all aquifers. Wells in bedrock yield at least one to two gallons per minute at most sites. The probability of adequate yields for domestic supply is greater from sedimentary than from crystalline bedrock and is also greater from stratified-drift overburden than from till. The quality of water from all sources in the basin is good except where adversely affected by swamp drainage, aquifer composition or human activities. The water is generally low in dissolved-solids concentration and is soft to moderately hard. Surface water is less mineralized than ground water, especially during high-flow conditions when it is primarily direct runoff. Samples of water collected from 20 streams during high flow had 34 mg/L median dissolved-solids concentration and 16 mg/L median hardness. Samples collected from the same sites at low flow had 52 mg/L median dissolved solids and 28 mg/L median hardness. In contrast, water from wells had 112 mg/L median dissolved-solids concentration and 60 mg/L median hardness. Iron and manganese occur in objectionable concentrations ~n a few parts of the basin where streams drain swamps and aquifers are rich in iron- and manganese-bearing minerals. Five percent of streams at high flow, 21 percent at low flow, and 7 percent of ground-water samples contained iron in sufficient concentration to cause stains on plumbing fixtures and laundry. Human activities have modified the quality of water in parts of the basin. The high bacterial content of the Pequabuck River. and the high nitrate and chloride concentrations in some ground-water samples, are evidence of man&rsquo;s influence. The quantity and quality of water in the basin&rsquo;s streams and aquifers are satisfactory for a wide variety of uses. and, with suitable treatment, may be used for most purposes. The total amount of water used by 21 principal public supplies within the basin was 29 billion gallons in 1970. About 70 percent of this was used for domestic and commercial purposes, and nearly 30 percent was used by industry. Analyses of water from these systems show good quality.</p>","language":"English","publisher":"Connecticut Department of Environmental Protection","collaboration":"Prepared by the U.S. Geological Survey in cooperation with the Connecticut Department of Environmental Protection","usgsCitation":"Handman, E.H., Haeni, F.P., and Thomas, M.P., 1986, Water resources inventory of Connecticut Part 9: Farmington River basin: Connecticut Water Resources Bulletin 29, Report: viii, 91 p.; 4 Plates: 38.67 x 42.36 inches and smaller.","productDescription":"Report: viii, 91 p.; 4 Plates: 38.67 x 42.36 inches and smaller","numberOfPages":"101","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":286022,"rank":6,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/70038342.jpg"},{"id":311385,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/unnumbered/70038342/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":286018,"rank":2,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/unnumbered/70038342/plate-a.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":286021,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/unnumbered/70038342/plate-d.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":286019,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/unnumbered/70038342/plate-b.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":286020,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/unnumbered/70038342/plate-c.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"48000","country":"United States","state":"Connecticut","otherGeospatial":"Farmington River Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -73.30215454101562,\n              41.53839396783225\n            ],\n            [\n              -73.30215454101562,\n              42.04317376494972\n            ],\n            [\n              -72.68280029296875,\n              42.04317376494972\n            ],\n            [\n              -72.68280029296875,\n              41.53839396783225\n            ],\n            [\n              -73.30215454101562,\n              41.53839396783225\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bcb7fe4b08c986b32d69f","contributors":{"authors":[{"text":"Handman, Elinor H.","contributorId":31748,"corporation":false,"usgs":true,"family":"Handman","given":"Elinor","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":463911,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haeni, F.

Flight in the male and incubation in the female were major components of the DEB early in the season, whereas cost of molt was a major component for both sexes near the end of the season. Our estimates of longspur DEB based on a time-activity approach were similar to those based on a cage existence model. Minor differences are explained by increased male territorial activity, by energy savings of the female during incubation, and by contraction of the molt for both sexes within the short summer season. Male and female longspurs were estimated to capture 3000 to 10,000 seeds and insects d<sup>-1</sup> (3-20 items min<sup>-1</sup> foraging) for self maintenance while in summer residence near Barrow. Each adult was estimated to capture an additional 3000 insects d<sup>-1</sup> ( 6-7 insects min<sup>-1</sup> foraging) during the peak energy requirements to raise five young. While raising young, the maximum required capture rate of prey per time foraging for each adult occurred during the nestling stage; young are just achieving independence, however, when food supply is at a maximum.</p>","language":"English","publisher":"INSTAAR, University of Colorado","publisherLocation":"Boulder, CO","doi":"10.2307/1551091","usgsCitation":"Custer, T., Osborn, R.G., Pitelka, F., and Gessaman, J., 1986, Energy budget and prey requirements of breeding lapland longspurs <i>Calcarius lapponicus</i> near Barrow Alaska, U.S.A.: Arctic and Alpine Research, v. 18, no. 4, p. 415-428, https://doi.org/10.2307/1551091.","productDescription":"14 p.","startPage":"415","endPage":"428","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":258934,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","city":"Barrow","volume":"18","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0945e4b0c8380cd51e4f","contributors":{"authors":[{"text":"Custer, T.

Internally consistent motions are determined assuming that these faults bound rigid blocks. Relative to North America, most of California west of the San Andreas fault is moving parallel to the San Andreas fault through the Transverse Ranges and not parallel to the motion of the Pacific plate. This is accomplished by counterclockwise rotation of California south of the San Andreas fault and by the westward movement of central California north of the Gar lock fault. The velocities of the blocks are calculated along several paths in southern California that begin in the Mojave Desert and end off the California coast. A path that crosses the western Transverse Ranges accumulates the accepted relative North America-Pacific plate velocity, whereas paths to the north and south result in a significant missing component of motion. This implies the existence of a zone of active deformation in southern California that is interpreted to include the western Transverse Ranges and northwest trending, predominately strike-slip faults close to the coast both north and south of the Transverse Ranges. Strain on this system accounts for about a third of the total North America-Pacific plate motion.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/TC005i001p00033","issn":"02787407","usgsCitation":"Weldon, R., and Humphreys, E., 1986, A kinematic model of southern California: Tectonics, v. 5, no. 1, p. 33-48, https://doi.org/10.1029/TC005i001p00033.","productDescription":"16 p.","startPage":"33","endPage":"48","costCenters":[],"links":[{"id":225856,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"southern California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.95429455591723,\n              36.479023833519804\n            ],\n            [\n              -121.95429455591723,\n              32.61748294993062\n            ],\n            [\n              -114.28321931595231,\n              32.61748294993062\n            ],\n            [\n              -114.28321931595231,\n              36.479023833519804\n            ],\n            [\n              -121.95429455591723,\n              36.479023833519804\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"5","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-07-26","publicationStatus":"PW","scienceBaseUri":"5059e42ce4b0c8380cd4647d","contributors":{"authors":[{"text":"Weldon, R.","contributorId":99307,"corporation":false,"usgs":true,"family":"Weldon","given":"R.","affiliations":[],"preferred":false,"id":369480,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Humphreys, E.","contributorId":43112,"corporation":false,"usgs":true,"family":"Humphreys","given":"E.","email":"","affiliations":[],"preferred":false,"id":369479,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Cool desert shrublands are extensively managed as grazing lands, and are defoliated annually by domestic livestock.

Turkey vulture eggshells were 16% thinner than the pre-DDT mean; there was no change in shell thickness of raven eggs. Vulture eggs contained an average of 6.9 ppm DDE and two contained excessive concentrations of endrin. DDE concentrations were low in raven eggs.

Although all known nests have been natural cavities, some have been little more than overhung ledges on cliffs, while others have been deep, dark caves with nest chambers completely concealed from the outside. Two sites have been cavities in giant sequoias (Sequoiadendron giganteum). Contrary to previous assumptions, condors do modify the characteristics of their nest sites significantly and commonly construct substrates of coarse gravel on which to rest their eggs. Many nests have been completely accessible to terrestrial predators, many have been poorly protected from avian predators, and some have had structural flaws leading directly to nesting failure. The use of suboptimal sites has not been clearly related to a scarcity of better quality sites.","language":"English","publisher":"Oxford Academic","doi":"10.2307/1368920","usgsCitation":"Snyder, N., Ramey, R., and Sibley, F., 1986, Nest-site biology of the California condor: Condor, v. 88, no. 2, p. 228-241, https://doi.org/10.2307/1368920.","productDescription":"14 p.","startPage":"228","endPage":"241","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":480122,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.usf.edu/condor/vol88/iss2/13","text":"External Repository"},{"id":197949,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"88","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae77c","contributors":{"authors":[{"text":"Snyder, N.F.R.","contributorId":59383,"corporation":false,"usgs":true,"family":"Snyder","given":"N.F.R.","email":"","affiliations":[],"preferred":false,"id":335493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ramey, R.R.","contributorId":70883,"corporation":false,"usgs":true,"family":"Ramey","given":"R.R.","affiliations":[],"preferred":false,"id":335494,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sibley, F.C.","contributorId":79971,"corporation":false,"usgs":true,"family":"Sibley","given":"F.C.","email":"","affiliations":[],"preferred":false,"id":335495,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation. Two diets low in protein and energy simulated stress diets.       Feed intake during the 1979-80 winter, when diets varied the most, was 30% higher for canvasbacks fed the low energy (1543 kcal/kg) diet than for canvasbacks fed the high energy (3638 kcal/kg) diet. Body weight of males and females did not differ between groups fed different diets, but there were seasonal differences (P < 0.05) for both sexes aggregated across diets. Feed intake and body weights were greatest in November and April and least in January and February. Convasbacks lost weight and ate less during the most stressful periods despite ad libitum feed supplies. No differences could be detected in the behavior of captive canvasbacks as a result of the diets they received. Differences due to season and sex were observed for some behaviors. Inactivity increased (P < 0.05) during the winter apparently as a mechanism to conserve energy.Overall, captive canvasbacks were able to maintain themselves during winter on diets with as little as 10% protein and 1543 kcal/kg provided adequate quantities of food were available. Availability of low energy food (e.g. clams) may be the limiting factor in regard to winter survival of wild canvasbacks. The distribution and abundance of canvasbacks in some wintering areas ultimately has been influenced by the quantity and probably the quality of available nutrients.Data from this study indicate that canvasbacks are unable to adjust intake rates to compensate for low energy foods and may subsequently store less fat or modify behavior and microclimate. However, decreased weight, feed intake, and activity of ducks fed ad libitum rations occurred in mid-winter irrespective of diet quality and appeared to be an endogenous component of their annual cycle which persists in captivity. These changes apparently have a selective advantage of increasing the probability of survival in ducks by decreasing energy expenditure during periods of winter stress.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Dissertation Abstracts International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Perry, M., 1986, Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria): Dissertation Abstracts International, v. 46B, no. 10.","productDescription":"3291 (abstract)","startPage":"3291 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198143,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46B","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f5e4b07f02db5f0c50","contributors":{"authors":[{"text":"Perry, Matthew C. 0000-0001-6452-9534","orcid":"https://orcid.org/0000-0001-6452-9534","contributorId":16372,"corporation":false,"usgs":true,"family":"Perry","given":"Matthew C.","affiliations":[],"preferred":false,"id":338004,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
