Rising temperatures, including heat waves, have the potential to profoundly influence coastal, marine, and estuarine systems. What unique considerations must be evaluated to understand these effects from both ecological and human perspectives?
A new study led by researchers at UC Santa Cruz, with coauthors from UC Berkeley, UCLA, UC Santa Barbara, and UC Davis, documents the collapse of kelp forest ecosystems off the coast of Northern California. Analyzing the contributing events, from warming oceans to the loss of sunflower sea stars, researchers used satellite imagery from over 30 years to assess historical changes and better understand the dynamics and resilience of kelp forests.
Using science to inform the restoration of California’s underwater forests
Kelp forests are underwater forests that support some of the world’s most productive fisheries and unique ecosystems. Kelp forests occur throughout the world. California’s kelp forests are particularly unique, as our “redwood forests of the sea” are among the tallest and most productive of the world: Northern California’s “bull kelp” grow an average of 4 in./day and can reach heights over 100 ft.
