Research in the earth sciences routinely yields a wealth of
observational data and results spanning a range of disciplines,
including geophysics, chemistry, theoretical fluid mechanics and
biology. As yet though, this complementary information has not
been fully utilized. Most of it exists either in inert, noninteractive form
(e.g. journal publications) or as unlinked and incompatible data sets
and models. Scientists studying mid-ocean ridges have taken the
first steps in data archiving, but mere collections of publicly available
data will not be sufficient. Scientists will need a wide range of
sophisticated programming support to coordinate the use of data,
computational tools, and numerical models across distributed
networks of computers.
Tool Composition: VRV-ET
Faculty: Jan Cuny and Doug Toomey (U of O)
System Designer: Joshua Rogers (U of O)
In conjunction with our VRV-1 research, we are building a prototype
set of tools that support web-based collaboration. These tools,
which will eventually form the interface for the VRV-1 environment,
are being used, tested, and evaluated in building an exhibit entitled,
the Volcanic Galapagos (Figure 1). The tools are designed
to allow scientists/educators at remote locations to participate
collaboratively in the design and evolution of our exhibit. This will
allow us to keep the web-based content current with the diverse
scientific efforts of a team of researchers and it will enable other
researchers to add material.

Web-Based GIS
Faculty: Dawn Wright (OSU)
Student: Liz O'Dea (OSU; now at the
Irish Coastal & Marine Resources
Centre)
Spatial data can be viewed using Arc Internet Map Server (ArcIMS),
an online GIS that allows users to perform GIS functions such as
spatial query, buffering, clipping, and spatial network analysis over
the Internet (Figure 2). ArcIMS has the potential for
allowing simultaneous
access to both web data from the server and local data from the
client's desktop, as well as the ability to dynamically edit and
annotate maps. EPR data are being compiled from several
resources to create a Virtual Research Vessel prototype atlas
powered by ArcIMS, thereby facilitating a simpler way for finding
and viewing data, translating between formats, and encouraging
future data submission to archives.

ArcIMS offers a method of dynamically viewing spatial data on-line.
