CCALMR EBS OGI OHSU

CORIE is maintained by the Center for Coastal and Land-Margin Research (CCALMR), a center of the Department of Environmental and Biomolecular Systems (EBS), OGI School of Science & Engineering (OGI), Oregon Health & Science University (OHSU). Major aspects of the CORIE infrastructure are described below:

Physical Location

CORIE is operated from offices at the OHSU-West Campus in Beaverton, Oregon, and from a field station at the MERTS Campus of the Clatsop Community College, in Astoria, OR. Located off Cathlamet Bay, a lateral bay in the Columbia River estuary, the field station is approximately a two-hour drive from the OHSU-West Campus offices.

Computational Facilities

The computational facilities are located at the OHSU-West Campus. We rely on institutional and department resources for network infrastructure, Internet2 access, and video conferencing capabilities, but maintain autonomously the following equipment:

32 bit Compute Cluster: This primary compute cluster is composed of 16 dual 2.4GHz 32 bit Intel CPU nodes. Each of the cluster nodes contains 4GB of main memory and 36GB local disk. Nodes on the cluster may be used independently or as part of a Beowulf parallel computer supporting both PVM and MPI parallel libraries.

64 bit Compute Cluster: A general-purpose compute cluster is composed of six 667MHz DEC Alpha servers. Each server contains 4GB main memory and 18GB local disk storage. Node on the Alpha cluster may be used independently or as part of a Beowulf parallel computer supporting both PVM and MPI parallel libraries.

Cluster Storage: Storage for the clusters and other servers is provided through 3 Network Attached Storage servers with a total of 8TB of online storage.

Cluster Interconnect: The compute clusters and file servers are interconnected through a dedicated Cisco 4006 switch with 72 1Gbps copper ports and 3 1Gbps optical fiber ports.

Other Compute Severs: Miscellaneous additional computer servers include seven DEC Alpha clones and a SGI Origin server.

Field Facilities

The CORIE observation network is maintained from the Astoria field station.

Vessels: Routine maintenance of the various stations of the observation network is performed from a CCALMR operated vessel, the 18ft RIB RV CORIE. For operations requiring larger vessels Clatsop Community College's 50ft MV Forerunner has been outfitted with a hull-mounted ADCP and a flow-through thermosalinigraph; also available are oceanographic winches, cranes and precision navigation equipment.

Field Instrumentation: CCALMR maintains instrumentation at approximately 18 stations in or around the Columbia River and other Oregon estuaries. Instrumentation at these stations consists primarily of combinations of Acoustic Doppler Profilers measuring water velocity, CTs and CTDs determining water temperature, salinity and depth; these instruments are scattered both geographically and vertically. In addition, a few meteorological stations are maintained, measuring wind and air properties, and determining solar radiation at different wavelengths. Almost all stations use spread spectrum radio modems to relay data to networked base stations for display via the world wide web, in near real time.
