Some Current Work at Terra Cognita

Arctic Archive for Geophysical Research: Unlocking Undersea Knowledge (AAGRUUK)

AAGRUUK is a collaboration of the Hawai'i Mapping Research Group (University of Hawai'i SOEST) with OSU Geosciences via Davey Jones Locker and Terra Cognita. It is funded by the NSF Office of Polar Programs. For researchers wishing to access arctic data, AAGRUUK is being developed to provide: (1) rapid access to raw and processed marine geology and geophysics data, especially data that presently are not supported at traditional data repositories such as the National Geophysical Data Center (e.g., SCICEX sidescan and phase-difference bathymetry, USCGC Healy SB2112 amplitude and backscatter data); (2) access to metadata, contact and reference information; (3) establish standards for data archival, documentation and presentation; (4) promote collaborative research and multidisciplinary studies, thereby fostering new scientific insights. Minnesota MapServer, Storage Resource Broker, and SIOExplorer DIGIARCH are some of the approaches being employed. Aagruuk is also the "morning star" of the Inupiat people, rising above the horizon each December to signal the end of the long winter night.

Virtual Oregon Natural Resources Data Clearinghouse

The development of innovations in the cataloging and distribution of place-based (geospatial) environmental data of Oregon, along with education and outreach throughout the state on how best to incorporate various data sets, images, and geospatial tools into classroom teaching and environmental activism. Our new catalogue will have innovative features such as authentication, platform services, access control, and the ability to manage different web services for data flow, backup, load balancing, etc. Planned innovation outcomes include a main metadata and data catalogue incorporating statewide, federal, and library metadata standards; a backend framework to link the catalog to actual data sets or web links that lead to external data sets; a web portal of data (with accompanying tools, and services); training workshops for faculty, agencies and non-governmental organizations; and training sessions and educational modules for K-12 teachers and the general public (GIS Day). Virtual Oregon is a collaboration between the OSU Valley Library, the Department of Geosciences, the College of Forestry, and the Northwest Alliance for Computational Science and Engineering (NACSE).

Transboundary Freshwater Dispute Database

To aid in the assessment of the process of water conflict prevention and resolution, over the years Dr. Aaron Wolfe and his students have developed the Transboundary Freshwater Dispute Database, a project of the Department of Geosciences, in collaboration with the NACSE. In this database, biophysical, socioeconomic, and geopolitical data relating to the world's international river basins are accessible and searchable through spatial and tabular formats. Spatial data, searchable at the international river basin and/or country scale, include climate, discharge, runoff, land cover, dam density, irrigation and population.

American Samoa Project

Graduate students of Dr. Dawn Wright are developing classifications of the benthic (ocean floor) habitats around American Samoa. To date, multibeam bathymetry and backscatter surveys have been completed for six areas around the main island of Tutuila. The benthic habitat classifications of these areas will be incorporated in to a web-based GIS for the coral reef resources in American Samoa, including Fagatele Bay National Marine Sanctuary and the National Park of American Samoa. The site will have both an English interface and a Samoan interface. Photos from the National Park of American Samoa and the Manu'a Islands of American Samoa.

The Oregon Biodiversity Analysis Project

The Oregon Biodiversity Analysis Project, sponsored by the Biodiversity Research Consortium examines species diversity for the state of Oregon using a hexagonal grid system. The set coverages and integer programming algorithms provide a sequence of locations that maximize the number of species classes represented at each step. Richness maps cover class diversity; terrestrial vertebrate diversity; rare, threatened and endangered species diversity; and vegetation cover diversity.

The Global Grid Project

The Global Grid Project, sponsored by the US EPA, addresses improved cartographic methods for sampling and analyzing environmental phenomena across the globe. The project is a study of the performance of alternative ways to partition the globe into sample units. The current work looks at the icosahedron the regular three-dimensional polyhedron with 20 faces, and measures distortion in shape and area for different types of subdivision. Ongoing work will look at other polyhedra and implement one or more types of subdivision to test performance of database and analysis operations.

Gosh, this sounds real interesting, do you have an animated image that illustrates what you mean? Funny you should ask... . Note - some browsers are incapable of displaying animated images. If you cannot view the linked image, or is is not moving, you are probably not using the latest browser software or have had too much coffee.

The Iowa Project

This research explores potential effects of alternative land use and management choices on water quality and biodiversity in the United States Corn belt. Designed future scenarios and GIS-based models are used to evaluate the potential impact of different public attitudes and policy choices in agricultural watersheds.

The Turtles of the World Database

Originally built as a proof-of-concept design for a near-real-time database of all tortoises and freshwater turtles in the world. The National Science Foundation has funded a 2-year effort to build a more extensive version that will support both professional and amateur herpetologists around the globe in documenting the dynamic record of turtle species. Work begins in September 1998 and is based primarily on the efforts of John B. Iverson of Earlham College.

Mojave Desert Biodiversity Project

Analysis and Assessment of Impacts on Biodiversity: A Framework for Environmental Management on DoD Lands within the California Mojave Desert. Funded by the Strategic Environmental Research and Development Program (SERDP).
