Temperature (T in °C) and mean vitrinite reflectance (Rm in %) of sedimentary organic matter samples from six liquid-dominated geothermal systems plot about a line approximated by a regression equation of the form Rm = 0.435 exp 0.00683T. The reflectance data from these systems are strongly temperature-dependent, with a coefficient of determination (r2) of 0.8. Geologic evidence indicates that reaction duration ranges from 103 or 104 to 106 yr in these systems that appear to have near-maximum temperatures. The uncertainty in vitrinite reflectance and temperature determinations must account for a large part of the remaining variability not explained by the regression equation; therefore, the strong temperature dependence of Rm indicates that after about 104 yr, reaction duration has little or no influence on metamorphism of organic matter in liquid-dominated geothermal systems. These data indicate that vitrinite reflectance can be used to determine the maximum temperature reached in hot sedimentary basins of moderate longevity.
Examination of SEASAT SAR images of eastern Maryland and Virginia reveals botanical distinctions between vegetated lowland areas and adjacent upland areas. Radar returns from the lowland areas can be either brighter or darker than returns from the upland forests. Scattering models and scatterometer measurements predict an increase of 6 dB in backscatter from vegetation over standing water. This agrees with the SCWigital number (DN) increase observed in the digital SEASAT data. The brightest areas in the Chickahominy, Virginia, drainage, containing P. virginica about 0.4 m high, contrast with the brightest areas in the Blackwater, Maryland, marshes, which contain mature loblolly pine in standing water. The darkest vegetated area in the Chickahominy drainage contains a forest of Nyssa aquatica (water tupelo) about 18 m high, while the darkest vegetated area in the Blackwater marshes contains the marsh plant Spartina alterniflora, 0.3 m high. The density, morphology, and relative geometry of the lowland vegetation with respect to standing water can all affect the strength of the return L band signal.

The purpose of these burns was to improve wildlife habitat and manipulate native prairie vegetation. All of the fires occurred in grassland and shrubsteppe vegetation types. Fuels were predominantly grasses and forbs intermixed with patches of shrubs. Nearly all of the fuels were <1.5 m tall. Shrub stems averaged <2.5 cm in diameter.In northern grasslands, prescribed burns can be conducted successfully during all months when there is no snow or ice cover on the ground. However, the burns analyzed here were conducted between March and October during all hours of the day or night.Burns were conducted under a wide range of environmental conditions. For example, one plot of mixed-grass prairie burned successfully just 9 hours after it received 1.2 cm of rain; another plot of mixed-grass prairie burned successfully when ambient air temperature was only 1.7 deg.C. Heavy fuels will often burn for short periods of time though light rain or snow are falling.Precipitation, relative humidity, temperature, cloud cover, and wind speed and direction are important climatic factors to consider before and during prescribed burns. These factors influence ignition of fuels, fire behavior, and fire effects. The 4 basic environmental conditions that influence the burning of northern plains grasslands and shrubsteppe are those that:1) Prohibit ignition or spread of fires. Plots with complete snow or ice cover, or those ignited during rainfall rates >0.05 cm/h, do not burn. However, these are good conditions to burn stockpiles of unwanted fuels that are usually high risk elements during regular prescribed burns.2) Produce partial burns. Partial burns are defined as those where fire is discontinuous and patches of standing and lodged vegetation are left unburned. Partial burns occur most often when fine fuels feel moist when handled, where less than 2 days have passed since the last measurable precipitation, and when cloud cover is complete. Other conditions associated with partial burns are relative humidities >50 percent, temperatures <21 deg.C, and wind speeds <10 km/h. These conditions occur most often during May and June.3) Produce complete burns. Complete burns are defined as those in which fire is continuous and nearly all vegetation (standing, lodged, and ground litter) is consumed by the fire. Complete burns occur most often when fine fuels feel dry when handled, 2 or more days have passed since the last measurable precipitation, and the sky is partly cloudy to clear. Complete burns occur with relative humidities between 25 and 50 percent, temperatures between 21 and 32 deg.C, and wind speeds of 13 to 24 km/h. These conditions occur most often in July, August, and September, but can occur anytime from March through November.4) Produce high risk fires. High risk fires are defined as those fires that are conducted during undesirable climatic conditions. High risk fires can always be expected with a combination of high winds, low humidity, high temperatures, and no recent precipitation. These conditions are most probable with wind speeds >32 km/h, relative humidities <20 percent, and temperatures >35 deg.C. These conditions occur most often in July, August, and September, but can occur anytime from April through October.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Management of public lands in the Northern Great Plains","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"The Wildlife Society; North Dakota Game and Fish Dept.; U.S. Fish and Wildlife Service","publisherLocation":"Bismarck, ND","usgsCitation":"Kruse, A., Higgins, K., and Piehl, J., 1983, Environmental factors that influence prescribed burning in the Northern Plains, chap. of Management of public lands in the Northern Great Plains, p. 31-32 [43 pp.].","productDescription":"p. 31-32 [43 pp.]","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":128071,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a13e4b07f02db60238f","contributors":{"authors":[{"text":"Kruse, A.D.","contributorId":19900,"corporation":false,"usgs":true,"family":"Kruse","given":"A.D.","email":"","affiliations":[],"preferred":false,"id":295952,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Higgins, K.F.","contributorId":55767,"corporation":false,"usgs":true,"family":"Higgins","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":295954,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Piehl, J.L.","contributorId":54536,"corporation":false,"usgs":true,"family":"Piehl","given":"J.L.","affiliations":[],"preferred":false,"id":295953,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70011375,"text":"70011375 - 1983 - New evidence for the age of the Gubik Formation Alaskan North Slope","interactions":[],"lastModifiedDate":"2013-01-26T15:54:58","indexId":"70011375","displayToPublicDate":"1983-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3218,"text":"Quaternary Research","active":true,"publicationSubtype":{"id":10}},"title":"New evidence for the age of the Gubik Formation Alaskan North Slope","docAbstract":"At several Alaskan North Slope localities south of the shore of the Arctic Ocean the Gubik Formation, herein regarded as latest Pliocene and Pleistocene in age, contains a marine unit at its base.

Although these mammals have poorly known fossil histories, consideration of what is known suggests that the basal marine unit near Ocean Point is of latest Pliocene age, between 2.2 and 1.7 my old, and that the marine unit near Teshekpuk Lake is probably late Pleistocene, most likely correlating with the Sangamon Interglaciation and about 120,000 yr old. ?? 1983.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(83)90041-8","issn":"00335894","usgsCitation":"Repenning, C., 1983, New evidence for the age of the Gubik Formation Alaskan North Slope: Quaternary Research, v. 19, no. 3, p. 356-372, https://doi.org/10.1016/0033-5894(83)90041-8.","startPage":"356","endPage":"372","numberOfPages":"17","costCenters":[],"links":[{"id":266562,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(83)90041-8"},{"id":221362,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a657be4b0c8380cd72be5","contributors":{"authors":[{"text":"Repenning, C.A.","contributorId":56700,"corporation":false,"usgs":true,"family":"Repenning","given":"C.A.","affiliations":[],"preferred":false,"id":360954,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":1013879,"text":"1013879 - 1983 - Using single board computers for control applications","interactions":[],"lastModifiedDate":"2023-12-13T01:02:02.557303","indexId":"1013879","displayToPublicDate":"1983-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1657,"text":"Fisheries","onlineIssn":"1548-8446","printIssn":"0363-2415","active":true,"publicationSubtype":{"id":10}},"title":"Using single board computers for control applications","docAbstract":"No abstract available.

Virus was never isolated from river water, but was found in water from the side channel at levels ranging from 32.5 to 1600 plaque-forming units (p.f.u.)/ml. Uninfected yearling sockeye salmon held in a box in the side channel developed localized gill infections with IHN virus. The disease did not progress to the viscera until a threshold titre of about 105 p.f.u./g was reached in the gill. The effectiveness of the gill as a barrier limiting development of systemic infections means that waterborne IHN virus probably does not greatly increase the infection rate in a sockeye salmon population during spawning.

The furrows are 10 to 50 m apart, 4 to 13 m deep, linear, and nearly parallel in water depths of 2,000 m. They have steep walls and flat floors 3 to 5 m wide, of fine-grained sediment. Mid-range sidescan-sonar images show that similarly furrowed surfaces are found on nearby areas of the lower continental slope, not associated with canyons. The furrows are overlain in places by Pleistocene sediments. Although they show evidence of erosional origin, they do not appear to be related to observed structures, and their straight, parallel pattern is not well understood. A general cover of flocky unconsolidated sediments implies that bottom-current erosion is not active now.

Survival rates were higher (P < 0.05) for males than for females in the preseason-banded sample and in 2 of 3 postseason samples; recovery rates were higher (P < 0.05) for females in 1 postseason sample. Survival rates of postseason-banded males were highest in the Mississippi Flyway, whereas rates for females were highest in the Atlantic Flyway. The hypothesis of time-constant survival rates was rejected for all 3 samples of postseason-banded males, and 1 sample of females. The relationships of time-varying survival rates to annual indices of harvest rates and population density were examined. Survival rates of adult males in 1 postseason banding area were negatively correlated with harvest rate (r = -0.78, P < 0.01) and breeding population indices (r = -0.68, P < 0.05). The results are interpreted and discussed in terms of the hypotheses of compensatory and additive mortality, and suggestions are offered for future studies into the relationship between harvest and total mortality.

To construct the system, the transducers of a commercial side-scan system (frequency 105 kHz; pulse length 0.1 ms; horizontal beam width 1°; vertical beam width 20°; beam depressed 10° with respect to horizontal) were mounted 2 m above the sea floor on a vertical shaft that had a rotation speed of 0.5 rpm.
\n\n
The radially collected sonar images are recorded linearly on a standard side-scan recorder. To convert the linear record to a radial record, the original moving record is photographed through a slit by a rotating camera, exposing a circular image on film.
\n\n
Records that are collected with this system offer several advantages over records that are collected with towed systems. Bottom features are presented in nearly true plan geometry, and transducer yaw, pitch, and roll are eliminated. Most importantly, repeated observations can be made from a single point, and bedform movements of <50 cm can be measured. In quiet seas the maximum useful range of the system varies from 30 m (for mapping ripples) to 200 m (for mapping 10-m wavelength sand waves) to 450 m or more (for mapping gravel patches).

A persistent decrease of porosity with depth, similar to that of chalks of the Gulf Coast, occurs in these rocks. We make no attempt to differentiate depositional or diagenetic facies which produce scatter in the porosity-depth relationship; the dominant data trends thus are functions of carbonate rocks in general rather than of particular carbonate facies. Carbonate strata with less than 20% porosity are absent from the rocks studied here.
Aquifers and aquicludes cannot be distinguished on the basis of porosity. Although aquifers are characterized by great permeability and well-developed vuggy and even cavernous porosity in some intervals, they are not exceptionally porous when compared to other Tertiary carbonate rocks in south Florida. Permeability in these strata is governed more by the spacial distribution of pore space and matrix than by the total volume of porosity present.
Dolomite is as porous as, or slightly less porous than, limestones in these rocks. This observation places limits on any model proposed for dolomitization and suggests that dolomitization does not take place by a simple ion-for-ion replacement of magnesium for calcium. Dolomitization may be selective for less porous limestone, or it may involve the incorporation of significant amounts of carbonate as well as magnesium into the rock.
The great volume of pore space in these rocks serves to highlight the inefficiency of early diagenesis in reducing carbonate porosity and to emphasize the importance of later porosity reduction which occurs during the burial or late near-surface history of limestones and dolomites.

to -1.3% (x = -0.9%). Modern Halimeda segments from the same area have a measured delta18 O ranging from -2.0% to -2.5% PDB (x = -2.15%), and the carbonate skeleton appears to have formed in isotopic equilibrium with the oceanic waters on the platform. Biologic and geochemical data indicate that the sand deposits have accumulated under physical and chemical conditions similar to the modern shelf environment. 14 C data suggest that the sand was deposited over an approximate 5800-year span, centering about 4000 years B.P. The average isotopic difference of 1.25% between the Holocene and modern carbonate indicates that the late Holocene Halimeda lived in waters approximately 4 degrees cooler than the present.

Because the surfaces of both organic and inorganic particles have high affinities for pollutants, such as certain trace metals, chlorinated hydrocarbons, and petroleum (Bothner et al., 1981a), suspended matter plays a major role in the transport and fate of pollutants introduced into shelf and coastal waters. Although the composition of bottom sediments on the shelf off the northeastern United States is reasonably well known, the mineralogical composition and distribution of inorganic suspended matter is less well studied.

Sea-floor samples show that the sand has been derived (in situ) mainly from calcareous algae and molluscs. Zonation of the dominant sand producers is related to the present environmental setting; water depth has the greatest influence. Carbon-14 data (bulk sample) of cores indicate accumulation rates of slightly less than 1 mm/year for the last 5,000 years. Faunal studies show that the climate has remained constant over the past 5,000 years. The only changes in environmental conditions appear to have been an increase in water depth, changes in the patterns of water movement, and an increase in water temperature.

Five test holes were drilled and three of these were completed with 6-inch casings. Ground water in the eastern part of the study area is high in dissolved solids; water from well 5N/11E-36H1 contains 252,000 milligrams per liter of dissolved solids, and well 4N/12E-7R1 contains 21,800 milligrams per liter of dissolved solids. The dissolved-solids concentration in water from the test wells on the west side of Ludlow fault is much lower; the dissolved solids in water from the three test wells ranges from 669 to 961 milligrams per liter. The recommended limits for chloride and fluoride were exceeded in water from test well 4N/10E-21K1, arsenic and fluoride in water from well 5N/9E-3B1, and chloride in water from test well 6N/9E-34F1. An estimated 640,000 acre-feet of water is stored in the alluvium west of the Ludlow fault, sufficient to provide for several small diameter wells for many years.

Larvae of rainbow smelt (Osmerus mordax) dominated late spring and early summer catches and larvae of alewives (Alosa pseudoharengus) the midsummer catches. Larval yellow perch (Perca flavescens) were caught in early summer but were rarely the dominant species. The time of spawning and hatching, and thus occurrence of larvae, differed between areas but was less variable for alewives than for yellow perch. The appearance of larvae in Saginaw Bay was followed successively by their appearance in southern, central, and northern Lake Huron. Rainbow smelt were most abundant in northern Lake Huron and yellow perch and alewives in inner Saginaw Bay. Densities of either rainbow smelt or alewives occasionally exceeded 1/m3, whereas those of yellow perch never exceeded 0.1/m3. Abundance of alewives was usually highest 1 to 3 m beneath the surface and that of rainbow smelt 2 to at least 6 m beneath the surface. Important nursery areas of rainbow smelt were in bays and off irregular coastlines and those of yellow perch were in bays. All nearshore waters seemed equally important as nursery areas of alewives.

For all seasons and size groups of juvenile lake trout combined, the slimy sculpin (Cottus cognatus) was the principal forage fish, making up 42% (by weight) of identifiable fish remains. Young-of-the-year slimy sculpins were a major food of recently stocked yearling lake trout during July through October. Alewives (Alosa pseudoharengus) were the principal forage during April and May, and made up 28% (by weight) of the identifiable fish remains. They were rarely eaten during July and August, however, when lake trout remained in the hypolimnion and alewives were above it. Over 99% of the alewives eaten from April through August were yearlings and over 99% eaten during October were young-of-the-year. Rainbow smelt (Osmerus mordax) were the primary forage during July and August, but contributed only a small part of the diet during other seasons; overall, they made up 25% of identifiable fish remains.

St. Helens volcano suggest three different episodes; (1) 40,000–2500 years ago: eruptions of dacite with εNd = +5, εSr = −10, variable δ18O,206Pb/204Pb ∼ 18.76, Ca/Sr ∼ 60, Rb/Ba ∼ 0.1, La/Yb ∼ 18, (2) 2500-1000 years ago: eruptions of basalt, andesite and dacite with εNd = +4 to +8, εSr = −7 to −22, variable δ18O (thought to represent melting of differing mantle-crust reservoirs), 206Pb/204Pb= 18.81−18.87, variable Ca/Sr, Rb/Ba, La/Yb and high Zr, (3) 1000 years ago to present day: eruptions of andesite and dacite with εNd = +6, εSr = −13, δ18O∼6‰, variable206Pb/204Pb, Ca/Sr ∼ 77, Rb/Ba= 0.1, La/Yb ∼ 11. None of the products exhibit Eu anomalies and all are LREE enriched. There is a strong correlation between87Sr/86Sr and differentiation indices. These data are interpreted in terms of a mantle heat source melting young crust bearing zircon and garnet, but not feldspar, followed by intrusion of this crustal reservoir by mantle-derived magma which caused further crustal melting and contaminated the crustal magma system with mafic components. Since 1000 years ago all the eruptions have been from the same reservoir which has displayed a much more gradual re-equilibration of Pb isotopic compositions than other components suggesting that Pb is being transported via a fluid phase. The Nd and Sr isotopic compositions lie along the mantle array and suggest that the mantle underneath Mt. St. Helens is not as depleted as MORB sources. There is no indication of seawater involvement in the source region.
