Biological effects of the 1997/98 ENSO in Cook Inlet, Alaska Biological effects of the 1997/98 ENSO in Cook Inlet, Alaska
We have been conducting detailed studies of the biology of seabirds in relation to oceanography and forage fish ecology in lower Cook Inlet, Alaska, since 1995. This fortuitously allowed us to document biological effects of the 1997/98 ENSO in this region. Anomalously warm sea surface temperatures (SSTs) were observed in the Gulf of Alaska (GOA) beginning in June of 1997, but not in Cook...

Boreal partners in flight: Working together to build a regional research and monitoring program Boreal partners in flight: Working together to build a regional research and monitoring program
Boreal regions of western North America regularly support breeding populations of 130 species of landbirds, including 68 Nearctic-Neotropical migrants. Primary conservation concerns within the region include increased timber harvesting, insect outbreaks, fire suppression, mining, impacts of military training activities, urbanization, and recreational activities. Under auspices of...

Development of a long-term ecological monitoring program in Denali National Park and Preserve, Alaska (USA) Development of a long-term ecological monitoring program in Denali National Park and Preserve, Alaska (USA)
A Long-term Ecological Monitoring (LTEM) program began at Denali National Park and Preserve, Alaska (USA) in 1992, as a prototype for subarctic parks. The early history of the Denali LTEM program provides insight into the challenges that can arise during monitoring program development. The Denali program has thus far taken a watershed approach, involving collocation of study effort for a...

Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia
Two studies related to the regional environmental effects of coal mining in the Appalachian Plateau were conducted in 1998 as part of the National Water‐Quality Assessment program of the U.S. Geological Survey. The study area of about 20,000 square miles included parts of the Allegheny and Monongahela River basins in the north and the Kanawha River basin in the south. Water in domestic...
