Hanna Shoal Reports

walrus on ice

In the summer months of 2012 and 2013, the Hanna Shoal Ecosystem Study team conducted their research cruise aboard the USCGC Healy. This cruise focused on the water column and benthic trophic structure, sediment parameters, inventories of anthropogenic chemicals (trace metals and organics), and inventories of plankton, benthic and epibenthic fauna. Coincidently, the physical oceanographic study addressed water mass movements through direct measurement of circulation, density fields, ice conditions and modeling. This cruise also facilitated the collection of important marine mammal and seabird surveys conducted from the bridge whenever viewing conditions permitted.

With the cruises and analyses completed, you can view each year's cruise report and the final project report.
