Sea otters past and present perspectives Sea otters past and present perspectives
Sea otters have been an important resource for people living along the North Pacific coast for thousands of years. At least two aspects of the sea otters' natural history have linked them with humans: their pelt and their food habits. Sea otter pelts, arguably the finest in the animal kingdom, were fashioned into garments, particularly in northern latitudes, while the presence of sea...

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...

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...

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...

Geological and geophysical setting of the gold-silver vein systems of Unga Island, southwestern Alaska Geological and geophysical setting of the gold-silver vein systems of Unga Island, southwestern Alaska
The topic of this CD-ROM is the geologic framework of gold-silver vein deposits on Unga Island, in the Shumagin Islands, southwestern Alaska. The core of the publication is a new geologic map at a scale of 1:63,360 and aeromagnetic and electromagnetic survey data acquired by industry over the area of mineralization. Both the geologic map as well as a preliminary interpretation of the...

1997 volcanic activity in Alaska and Kamchatka: summary of events and response of the Alaska Volcano Observatory 1997 volcanic activity in Alaska and Kamchatka: summary of events and response of the Alaska Volcano Observatory
The Alaska Volcano Observatory (AVO) monitors over 40 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on pilot reports, observations of local residents and ship crews, and daily analysis of satellite images. In 1997, AVO responded to eruptive activity or suspect volcanic activity at 11...
