The heating of the postulated snow is assumed to be driven primarily by the absorption of solar radiation during clear sky conditions. Radiative heating rates are predicted as a function of depth and shown to be sensitive to the dust concentration and the size of the ice grains while the thermal conductivity is controlled by temperature, atmospheric pressure, and bulk density. Rates of metamorphism indicate that fresh fine-grained snow on Mars would evolve into moderately coarse snow during a single summer season. Results from global climate models are used to constrain the mean-annual surface temperatures for snow and the atmospheric exchange terms in the surface energy balance. Mean-annual temperatures within Martian snowpacks fail to reach the melting point for all atmospheric pressures below 1000 mbar despite a predicted temperature enhancement beneath the surface of the snowpacks. When seasonal and diurnal variations in the incident solar flux are included in the model, melting occurs at midday during the summer for a wide range of snow types and atmospheric pressures if the dust levels in the snow exceed 100 ppmw (parts per million by weight). The optimum dust concentration appears to be about 1000 ppmw. With this dust load, melting can occur in the upper few centimeters of a dense coarse-grained snow at atmospheric pressures as low as 7 mbar. Snowpack thickness and the thermal conductivity of the underlying substrate determine whether the generated snow-melt can penetrate to the snowpack base, survive basal ice formation, and subsequently become available for runoff. Under favorable conditions, liquid water becomes available for runoff at atmospheric pressures as low as 30 to 100 mbar if the substrate is composed of regolith, as is expected in the ancient cratered terrain of Mars.</p></div></div></div></div><div id=\"preview-section-introduction\"><br></div><div id=\"preview-section-snippets\"><br></div><div id=\"preview-section-references\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0019-1035(87)90123-0","issn":"00191035","usgsCitation":"Clow, G., 1987, Generation of liquid water on Mars through the melting of a dusty snowpack: Icarus, v. 72, no. 1, p. 95-127, https://doi.org/10.1016/0019-1035(87)90123-0.","productDescription":"33 p.","startPage":"95","endPage":"127","numberOfPages":"33","costCenters":[],"links":[{"id":225427,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"72","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1554e4b0c8380cd54d70","contributors":{"authors":[{"text":"Clow, G.D.","contributorId":46112,"corporation":false,"usgs":true,"family":"Clow","given":"G.D.","email":"","affiliations":[],"preferred":false,"id":367788,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The population decline of bloaters in recent decades was mainly attributed to exploitation, to the depression of chub recruitment (e.g. from inferred predation on early life stage) by nonendemic alewives (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax), and to complications arising from extreme female predominance that was best documented for Lake Michigan. The various interactions between bloaters and the nonendemic species, which were intensified after the loss of large predators to sea lamprey (Petromyzon marinus), would help to explain why a stock-recruitment relation was not shown for the Lake Michigan bloater. We hypothesize that reproductive inefficiency caused by a shift to strong female predominance in the bloater depresses recruitment and thus helps to regulate abundance. However, the low resilience that sex imbalance seems to impart makes the stock unstable when exploited. It should therefore be exploited conservatively during such periods.

The estimation techniques are evaluated by use of error analysis of simulated hydrograph characteristics (peak discharge, flood volume, and time to peak discharge). The hydrographs will be simulated with parameters estimated by the techniques for (1) 102 storms occurring at 36 gaged basins; and (2) a large storm system (one which produced floods with a 50-to 100-year recurrence interval).","conferenceTitle":"Engineering Hydrology, Proceedings of the Symposium.

The reservoir water column was i to 4&deg;C warmer in operational than in non-operational years. The thermo-dine was at depths of 5 to 15 m before the operation of Oconee Nuclear Station, but was always below the upper level of the intake (20 m) after the station was in full operation; this suggests that pumping by the Oconee Nuclear Station had depleted all available cool hypolimnetic water to this depth. As a result summer water temperatures at depths greater than 10 m were usually 10&deg;C higher after plant operation began than before. By fall the reservoir was nearly homothemious to a depth of 27 m, where a thermocine developed. Seasonal temperature profiles varied with distance from the plant; a cool water plume was evident in spring and a warm water plume was present in the summer, fall, and winter. A cold water plume also developed in the northern section of the reservoir due to the operation of Jocassee Pumped Storage Station. Increases in the mean water temperature of the reservoir during operational periods were correlated with the generating output of the power plant. The annual heat load to the reservoir increased by one-third after plant operations began. The alteration of the thermal stratification of the receiving water during the summer also caused the dissolved oxygen to mix to greater depths.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1752-1688.1987.tb00805.x","usgsCitation":"Oliver, J.L., and Hudson, P.L., 1987, Thermal and dissolved oxygen characteristics of a South Carolina cooling reservoir: Water Resources Bulletin, v. 23, no. 2, p. 257-269, https://doi.org/10.1111/j.1752-1688.1987.tb00805.x.","productDescription":"13 p.","startPage":"257","endPage":"269","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":133101,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"South Carolina","otherGeospatial":"Keowee Reservoir","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -82.8973388671875,\n              35.03449433167976\n            ],\n            [\n              -82.9522705078125,\n              35.07046911981966\n            ],\n            [\n              -83.04840087890625,\n              35.03449433167976\n            ],\n            [\n              -82.93304443359374,\n              34.89944783005726\n            ],\n            [\n              -82.98797607421874,\n              34.8047829195724\n            ],\n            [\n              -83.07037353515625,\n              34.76643521684169\n            ],\n            [\n              -82.97973632812499,\n              34.66258150231496\n            ],\n            [\n              -82.91656494140625,\n              34.72581233927868\n            ],\n            [\n              -82.8643798828125,\n              34.79350603426752\n            ],\n            [\n              -82.84790039062499,\n              34.84536693184101\n            ],\n            [\n              -82.8204345703125,\n              34.89494244739732\n            ],\n            [\n              -82.8973388671875,\n              35.03449433167976\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"23","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-06-08","publicationStatus":"PW","scienceBaseUri":"4f4e4a57e4b07f02db62e4f0","contributors":{"authors":[{"text":"Oliver, James L.","contributorId":97862,"corporation":false,"usgs":true,"family":"Oliver","given":"James","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":308540,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hudson, Patrick L. 0000-0002-7646-443X phudson@usgs.gov","orcid":"https://orcid.org/0000-0002-7646-443X","contributorId":5616,"corporation":false,"usgs":true,"family":"Hudson","given":"Patrick","email":"phudson@usgs.gov","middleInitial":"L.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":308539,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

After comparing spectral results of underivatized humic and fulvic acids with spectral results of chemically modified derivatives, that allow improved observation of the carbonyl group, the data clearly indicated that aromatic ketone groups comprised the majority of the carbonyl-group content. About one ketone group per monocyclic aromatic ring was determined for both humic and fulvic acids. Aromatic-ketone groups were hypothesized to form by photolytic rearrangements and oxidation of phenolic ester and hydrocarbon precursors; these groups have potential significance regarding haloform formation in water, reactivity resulting from active hydrogen of the methyl and methylene adjacent to the ketone groups, and formation of hemiketal and lactol structures. Aromatic-ketone groups also may be the point of attachment between aliphatic and aromatic moieties of aquatic humic-substance structure.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0146-6380(87)90038-6","usgsCitation":"Leenheer, J., Wilson, M.A., and Malcolm, R., 1987, Presence and potential significance of aromatic-ketone groups in aquatic humic substances: Organic Geochemistry, v. 11, no. 4, p. 273-280, https://doi.org/10.1016/0146-6380(87)90038-6.","productDescription":"8 p.","startPage":"273","endPage":"280","costCenters":[],"links":[{"id":226253,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Georgia","city":"Fargo","otherGeospatial":"Suwannee River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -82.55719563644614,\n              30.73718669262388\n            ],\n            [\n              -82.70468259143186,\n              30.595406491784985\n            ],\n            [\n              -82.62660258515855,\n              30.599762786732207\n            ],\n            [\n              -82.52104350470628,\n              30.666323175534032\n            ],\n            [\n              -82.33092442455035,\n              30.827183395185997\n            ],\n            [\n              -82.35189154748764,\n              30.855175569793232\n            ],\n            [\n              -82.55719563644614,\n              30.73718669262388\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"11","issue":"4","noUsgsAuthors":false,"plainLanguageSummary":"<p><br data-mce-bogus=\"1\"></p>","publicationStatus":"PW","scienceBaseUri":"505a8b3de4b0c8380cd7e1c7","contributors":{"authors":[{"text":"Leenheer, J.A.","contributorId":75123,"corporation":false,"usgs":true,"family":"Leenheer","given":"J.A.","affiliations":[],"preferred":false,"id":369541,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilson, M.

Sulfate-deposition rates in bulk sampling in New York during 1965-80 were approximately 40% of the average sulfur-emission rate for the Northeast. Sulfate-deposition rates in bulk and wetfall collectors were nearly equal and were five times greater than in the dryfall collector. Scavenging ratios for sulfate averaged 8.9 ?? 105; those for sulfate plus sulfur dioxide averaged 4.6 ?? 105. Sulfate concentrations in wet deposition averaged more than twice those estimated from published regional-scale washout equations, whereas those in dry deposition averaged only 22% of those computed from deposition velocities of 0.1 cm/s for sulfate and 1.0 cm/s for sulfur dioxide. Discrepancies in the dryfalls are attributed to inefficiency of dryfall-collection equipment. -from Author","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Northeastern Environmental Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Barnes, C., 1987, Relation of long- and short-term atmospheric sulfur concentrations to sulfate deposition in New York State: Northeastern Environmental Science, v. 6, no. 2, p. 89-98.","startPage":"89","endPage":"98","numberOfPages":"10","costCenters":[],"links":[{"id":225666,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a693e4b0e8fec6cdc20d","contributors":{"authors":[{"text":"Barnes, C.R.","contributorId":85625,"corporation":false,"usgs":true,"family":"Barnes","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":369451,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Assuming steady-state conditions, recharge within the drainage basin could account for both thermal and nonthermal ground-water discharge.
