Environmental variability facilitates coexistence within an alcid community at sea
J. Christopher Haney, Amy E.S. Schauer
1994, Marine Ecology Progress Series (103) 221-237
We examined coexistence at sea among 7 taxa of diving, wing-propelled seabirds (Alcidae) in the genera Aethia, Uria, Cepphus, and Fratercula. Species abundances were measured simultaneously with a suite of environmental factors in the northern Bering Sea, Alaska, USA; data from 260 adjacent and non-adjacent sites occupied by alcids foraging...

Various streamflow characteristics were estimated for water-reservation purposes for 17 sites in the lower Missouri River Basin and four sites in the Little Missouri River Basin in Montana. The characteristics were mean monthly and annual streamflow and monthly mean streamflow that is exceeded 90, 80, 50, and 20 percent of...
Hydrogeologic framework and preliminary simulation of ground-water flow in the Mimbres Basin, southwestern New Mexico

1994, Water-Resources Investigations Report 94-4011
The bolson-fill aquifer, the major water-yielding unit in the Mimbres Basin, southwestern New Mexico, ranges in thickness from 0 to about 3,700 feet. Recharge to the bolson-fill aquifer occurs by infiltration of ephemeral streams that cross the basin margin, infiltration from precipitation and streamflow, ground-water underflow from adjacent basins, and...

1994, Book chapter, Marine mammals and the <i>Exxon Valdez</i>
In the months following the Exxon Valdez oil spill (EVOS), 994 sea otters (Enhydra lutris) from oil-spill-affected areas died (Doroff et al. 1993). Carcasses collected from these areas and otters that died in rehabilitation centers are included in this number. The actual number that died was probably much greater.Within days...

Spaulding Malcolm L.Bedford KeithBlumberg AlanCheng RalphSwanson Craig, editor(s)
1994, Conference Paper
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration and longitudinal alignment, differences in circulation and flushing exist. Spatially detailed hydrodynamic models were applied to each estuary to characterize these differences. The models were...
