Is GIS a tool or a science? The question is clearly important in the day-to-day operations of geography departments. Departments need to know if GIS is a tool that should be taught at the undergraduate level, or a science and thus a legitimate research specialty of faculty and graduate students. We summarize the debate on this question that was conducted on(More)
Cyberinfrastructure integrates advanced computer, information, and communication technologies to empower computation-based and data-driven scientific practice and improve the synthesis and analysis of scientific data in a collaborative and shared fashion. As such, it now represents a paradigm shift in scientific research that has facilitated easy access to(More)
During several decades of investigation, the East Pacific Rise seafloor-spreading center at 910°N has been explored by marine geologists, geophysicists chemists, and biologists, emerging as one of the best studied sections of the global mid-ocean ridge. It is an example of a region for which there is now a great wealth of observational data, results and(More)
This paper examines how various combinations of geographic information systems and simulation models have been used to advance knowledge of water resource assessment and management. The contribution of geographic information systems to the generation, management, and delivery of spatially distributed data, the advent of new geographic information systems(More)
Web-based metadata clearinghouses and catalogs are intended to help users locate and access geospatial data that may be spread across many physical locations. Their specialized thesauri and query interfaces can be a significant help to users who are already familiar with the subject area and know specifically what they are seeking. At the same time, they(More)
The Arc Marine data model is a generalized template to guide the implementation of geographic information systems (GIS) projects in the marine environment. It developed out of a collaborative process involving research and industry shareholders in coastal and marine research. This template models and attempts to standardize common ocean and coastal data(More)
To improve understanding of population structure, ecosystem relationships and predictive models of human impact in cetaceans and other marine megafauna, we developed geneGIS, a suite of GIS tools and a customized Arc Marine data model to facilitate visual exploration and spatial analyses of individual-based records from DNA profiles and photo-identification(More)
The toxicity of three acylurea insect growth regulators, chlorfluazuron (Atabron), teflubenzuron (Nomolt) and diflubenzuron (Dimilin), and the macrocyclic lactone, abamectin, was assessed against a laboratory, susceptible (FS) strain and a field (Cameron Highlands, Malaysia 1988) strain of the diamondback moth, Plutella xylostella (L.) using a leaf-dip(More)
Four new bathymetric maps of the Tonga Trench and forearc between 14 ◦S and 27 ◦S display the important morphologic and structural features of this dynamic convergent margin. The maps document a number of important geologic features of the margin. Major normal faults and fault lineaments on the Tonga platform can be traced along and across the upper trench(More)
