food web for Bering Sea fish and other species, graphic showing connections between species This is a path diagram for the Bering Sea and Aleutians Islands marine ecosystem. It shows linkages between ecosystem variables. Arrows correspond to suspected relationships. An arrow pointing from X to Y indicates that a change in X is estimated to cause a change in Y. The number next to each arrow shows the estimated magnitude of the change (red arrows indicate a negative change and blue arrows indicate a positive change).

Large whale entanglement responders attemot to free an entangled minke whale. One responder is in the bow of the boat and holding the control line while another use a dive mask to better visualize the entanglement configuration. Responders from the Center for Coastal Studies work to free an entangled minke whale on June 29, 2022. The animal was anchored in place after the whale had bitten down on a 20-pot trawl line. The team was able to cut the buoy line near the whale’s mouth, and the fisherman was able to recover the gear. Credit: Center for Coastal Studies; NOAA Permit No. 18786
