Since their discovery in 1977, hydrothermal vent communities have offered scientists
a unique glimpse into a world that is supported primarily by chemically derived
energy rather than direct energy from the sun. Furthermore, studies of hydrothermal
vent ecosystems have introduced scientists to amazing animals that have successfully
adapted to living...
Situated off the west coast of Vietnam in the Gulf of Thailand, Phu Quoc archipelago and its waters are well-known for their rich natural resources, especially the bounty of fishery resources. Under increasing pressure from the growing population, fishing, and tourism development, there is a strong need to formulate an...
Dramatic declines in several groundfish populations have occurred along
the U.S. West Coast during the last decade (PFMC 1999, Sampson 1997,
Ralston 1998, Bloeser 1999). One problem exacerbating these declines is
insufficient stock assessments, especially for species of west coast rockfish
(Family Scorpaenidae, Genus Sebastes) which comprise the core of...
Geographical data and information are virtually unlimited in their
quantity and are oftentimes scattered throughout a multitude of locations and stored
in various formats on a wide variety of platforms. The Oregon Coast Geospatial
Clearinghouse (OCGC) is a web-based central repository for metadata (data about
data) corresponding to collected data...
Web geographic information systems (GISs) and the Internet are now providing the connectivity necessary to support large-scale data access by a wide variety of users, including not just scientific researchers, but also policy-makers and marine resource managers. However, connectivity alone cannot ensure that those who need natural resource information will...
Dramatic declines in many species of demersal fishes off the West Coast have resulted in the designation of nine commercially important species as being overfished. While the causes of those declines are not clearly understood, the fact remains that a paucity of life history and abundance data exists for many...
The purpose of this work is to broaden the theoretical foundations of interpolation of spatial data, by showing how ideas and methods from information theory and signal processing are applicable to the the work of geographers. Attention is drawn to the distinction between what we study and how we represent...
Ecoregions are regions of relative homogeneity with respect to specific
ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing
awareness that effective management of environmental resources must be undertaken
with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial
framework for assessing, managing, and monitoring ecosystems that...
Overfishing of our national marine resources has degraded some of the most productive fishing regions in the Northwest Atlantic Ocean, most notably the Gulf of Maine and Georges Bank. These regions may have shifted from productive trophic regimes to a less than optimal state therefore reducing fishers’ catches and associated...
An Internet Map Server (IMS) web site was constructed with the goal of
helping middle- through high-school students learn about ocean processes. This IMS was
developed in conjunction with the activities of the Science & Math Investigative
Learning Experience (SMILE) program, and for eventual use with the Oregon Coastal
Atlas,...
