Extensive monitoring programmes viewed as long-term population studies: The case of North American waterfowl
J.D. Nichols
1991, Ibis (133) 89-98
Several long-running and geographically extensive survey programmes provide information used to make annual management decisions for North American waterfowl populations. Data from these programmes can also be viewed as resulting from long-term population studies and have formed the basis for a number of retrospective analyses. Short-term studies have been used...
Atmospheric organochlorine pollutants and air-sea exchange of hexachlorocyclohexane in the Bering and Chukchi Seas
D.A. Hinckley, T.F. Bidleman, C.P. Rice
1991, Journal of Geophysical Research (96) 7201-7213
Organochlorine pesticides have been found in Arctic fish, marine mammals, birds, and plankton for some time. The lack of local sources and remoteness of the region imply long-range transport and deposition of contaminants into the Arctic from sources to the south. While on the third Soviet-American Joint Ecological...
Observations at convergent margins concerning sediment subduction, subduction erosion, and the growth of continental crust
Roland E. von Huene, D.W. Scholl
1991, Reviews of Geophysics (29) 279-316
At ocean margins where two plates converge, the oceanic plate sinks or is subducted beneath an upper one topped by a layer of terrestrial crust. This crust is constructed of continental or island arc material. The subduction process either builds juvenile masses of terrestrial crust through arc volcanism or new...
Use of Wetland Habitats by Selected Nongame Water Birds in Maine

Earth Science Information Center
Water Resources Division, U.S. Geological Survey
1991, Report
An ESIC? An Earth Science Information Center. Don't spell it. Say it. ESIC. It rhymes with seasick. You can find information in an information center, of course, and you'll find earth science information in an ESIC. That means information about the land that is the Earth, the land that is...
