NOAA Fisheries scientists used modern acoustic technology to successfully verify the accuracy of old (1924-2003) maps of the Alaska sea floor and validate their use in managing sustainable fisheries.
When there is a large die-off of marine mammals, experts from NOAA Fisheries and our partners try to identify the reasons for what's known as an Unusual Mortality Event, or UME. Unfortunately, in about half of UMEs, a cause is never determined.
NOAA Fisheries-Alaska survey season off the Alaska coast is underway. Scientists use collected data to monitor trends and abundance of fish, crab and other species taken in commercial, recreational and subsistence fisheries throughout Alaska and to support biological and ecological studies. Under federal law, NOAA Fisheries is responsible for monitoring and managing marine resources in federal waters.
