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...
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...
Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...
The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...
The field of geography has been transformed in recent years through the use of spatial tools such as geographic information systems (GIS) satellite and acoustic remote sensing, the global positioning system (GPS), Internet mapping and more. Studying geography and earth science in the digital age now requires a sophisticated and...
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 Arc Marine data model is a generalized template to guide the implementation of geographic information systems (GIS) projects in the marine environment. Arc Marine developed out of a collaborative process involving research and industry shareholders in coastal and marine research. This template models and attempts to standardize common marine...
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...
Geographic information systems (GISs) offer a useful tool for educators to teach students about local and global communities in various subjects. GISs are increasingly being used in K-12 education, but that growth is hindered due to many teachers’ limited access to time or resources necessary to adequately learn a GIS...
Spatialization is an innovative way to expand searching capabilities for a
marine/coastal reference database by using a metaphorical map framework to establish
a sense of place for non-spatial information. Spatializing the Catalogue of Oregon
Marine and Coastal Information (COMC1), a coastal reference database, enables the
marine and coastal resource community...
