Electro-olfactograms - Neurobehavioral impacts of copper on juvenile salmon

Research support for various organizations in NOAA (Northwest Regional Office (NWR), HQ Office of Protected Resources, National Ocean Service (NOS) Coastal Services Center) for copper related to the harmful impacts of urban stormwater runoff, pesticide use, antifoulant use, and mining (e.g., proposed hardrock mining in Alaska). This has been a core focus of Ecotoxicology research for years, and may redirect to address key and high-profile data gaps specific to salmon habitat threats in Alaska.

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.
