Sea otter (Enhydra lutris) perspective: Part C. Trophic linkages among sea otters and bivalve prey in Prince William Sound, Alaska, in the aftermath of the Exxon Valdez oil spill: Implications for community models in sedimentary habitats Sea otter (Enhydra lutris) perspective: Part C. Trophic linkages among sea otters and bivalve prey in Prince William Sound, Alaska, in the aftermath of the Exxon Valdez oil spill: Implications for community models in sedimentary habitats
We exploited the Exxon Valdez oil spill in Prince William Sound (PWS), Alaska, to evaluate effects of reduced sea otter densities on prey populations in sedimentary habitats. We considered the need for and characteristics of new models for trophic effects of sea otters on coastal marine benthic communities. We viewed evidence for nonlinear or uncertain patterns of prey response to...

Sea otter (Enhydra lutris) perspective: Part B. Food limitation and the recovery of sea otters following the Exxon Valdez oil spill Sea otter (Enhydra lutris) perspective: Part B. Food limitation and the recovery of sea otters following the Exxon Valdez oil spill
We examined the potential role of food limitation in constraining recovery of sea otters in Prince William Sound, Alaska, following the Exxon Valdez oil spill. The spill resulted in the removal of a large number of sea otters in 1989, and as of 1998, the portion of the population in the heavily oiled northern Knight Island region had not fully recovered. Between 1996 and 1998, prey...

Harlequin duck (Histrionicus histrionicus) perspective: Harlequin duck population recovery following the Exxon Valdez oil spill: Progress, process, and constraints Harlequin duck (Histrionicus histrionicus) perspective: Harlequin duck population recovery following the Exxon Valdez oil spill: Progress, process, and constraints
Following the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska, we studied the status of recovery of harlequin duck (Histrionicus histrionicus) populations during 1995-1998. We evaluated potential constraints to full recovery, including (1) exposure to residual oil, (2) food limitation, and (3) intrinsic demographic limitations on population growth rates. In this paper, we...

U.S. Geological Survey 2002 petroleum resource assessment of the National Petroleum Reserve in Alaska (NPRA): play maps and technically recoverable resource estimates U.S. Geological Survey 2002 petroleum resource assessment of the National Petroleum Reserve in Alaska (NPRA): play maps and technically recoverable resource estimates
This report provides a summary of the estimated volume of technically recoverable undiscovered oil and nonassociated gas resources for each of the 24 plays evaluated in the U.S. Geological Survey 2002 petroleum resource assessment of the NPRA (Bird and Houseknecht, 2002). It also provides a set of illustrations showing the stratigraphic and geographic location of each play. Additional...

Fate of carbon in Alaskan Landscapes Project: Database for soils from eddy covariance tower sites, Delta Junction, AK Fate of carbon in Alaskan Landscapes Project: Database for soils from eddy covariance tower sites, Delta Junction, AK
Soils in Alaska, and in high latitude terrestrial ecosystems in general, contain significant amounts of organic carbon, most of which is believed to have accumulated since the start of the Holocene about 10 ky before present. High latitude soils are estimated to contain 30-40% of terrestrial soil carbon (Melillo et al., 1995; McGuire and Hobbie, 1997), or ~ 300-400 Gt C (Gt = 1015 g)...
