Episodic Upwelling of Zooplankton Within a Bowhead Whale Feeding Area near Barrow, AK
Our long term goals are to understand (1) the biological-physical oceanographic characteristics and mechanisms on the shelf near Barrow, AK that together produce a favorable feeding environment for the bowhead whale there and (2) the potential impact of climate change, particularly the ongoing reduc...
