Arctic Kelp Beds in the Beaufort Sea: Detection of Long-Term Change (BOEM)

This project is part of the long-term monitoring of Boulder Patch, a rock deposit region in Prudhoe Bay, to assess benthic biodiversity.


Arctic Marine Biodiversity Observing Network (AMBON)

This is an Arctic demonstration project located in the Chukchi Sea on how to incorporate biodiversity measurements into an ocean observing network.

COMIDA: Chukchi Sea Offshore Monitoring in Drilling Area: Epibenthic communities on and around Hanna Shoal

This project is describing the temporal and spatial variation of epibenthic organisms in the northern Chukchi Sea, particularly those around Hanna Shoal.


Evaluation of nearshore communities and habitats- Ecological Processes in Lower Cook Inlet

This project will describe and assess nearshore habitats in lower Cook Inlet and make recommendations for monitoring this pristine region.
