Hydrologic reconnaissance of the eastern North Slope, Alaska, 1975

Stream-icing zones in Alaska

“…At a few locations, aerial photographs were used to verify occurrences. Large icjngs prevjously mapped by Childers andothers (1975), Hall (1976;1980), Sloan and others (1?76), and Harden and others (1977), compare favorably with those mapped in this investigation.…”

“…(1919), Hall (1976;lP80), Childers andothers (1977), andF~rden andothers (1977). Icings along the route of the Trans-Alaska PipelSn~ were mapped by Sloan and others (1976), and local icings have been studied by Carlson (1979), Corbin (l977), Kane and Carlson (19771, K a~e and others (1973), PJwA (1982), and Slaughter (1987 Stream icSngs were interpreted from Landsat NSS (Multispectral scanner) data recorded during the 1972 to 1982 late-winter, spring, and summer seasons.…”

Overwintering Locations, Migrations, and Fidelity of Radio-Tagged Dolly Varden in the Hulahula River, Arctic National Wildlife Refuge, 2007–09

“…Summer flow levels are influenced primarily by melting snow and rainfall (Lyons and Trawicki, 1994), although during warm periods meltwater from Romanzof Mountain glaciers produces turbid flow in the Hulahula River as well (McCart, 1980). All surface flow ceases during winter, so aquatic habitat becomes limited to a few perennial springs (Craig and McCart, 1975;Childers et al, 1977;Kane et al, 2013). The springs have stable groundwater sources recharged by precipitation across porous limestone regions of the Brooks Range to the south (Hall and Roswell, 1981;Yoshikawa et al, 2007;Kane et al, 2013).…”

“…The river was a single channel at the capture location and braided in multiple channels from there downstream to the sea. Fishhole 1 is also the location of the farthest downstream perennial spring in the drainage (Craig and McCart, 1974;Childers et al, 1977) and was therefore the first location where all fish migrating upstream to spawn and overwinter would potentially be available for capture. Following capture, Dolly Varden were evaluated for tagging suitability.…”

The Sagavanirktok River, North Slope Alaska; characterization of an Arctic stream

“…It has been estimated that between the Saviukviayak River and Flood Creek springs, the amount of water contained in these icings is equivalent to an annual yield of almost 0.3m (1 ft) of water over the two basins. Since the annual precipitation for this upstream area is from 0.5 to 1.0 m (1.5 to 3.0 ft), this groundwater discharge plays a sizeable role in the hydrology of the Sagavanirktok River region (Childers et al, 1977). Because water is stored in the icings, downstream streamflow is initially reduced (Sloan et al, 1976).…”
