These include eastern boundary current upwelling systems such as those off the U.S. west coast along coastal California, Oregon and Washington, deep - sea and subsurface oxygen minimum zones, and coastal waters that are already experiencing excess nutrient levels (eutrophication) and low dissolved oxygen (hypoxia) due to human - driven nutrient pollution from land - based activities.

The lower Chesapeake Bay is especially at risk due to high rates of sinking land (known as subsidence).96 Climate change and sea level rise are also likely to cause a number of ecological impacts, including declining water quality and clarity, increases in harmful algae and low oxygen (hypoxia) events, decreases in a number of species including eelgrass and seagrass beds, and changing interactions among trophic levels (positions in the food chain) leading to an increase in subtropical fish and shellfish species in the bay.66
