Data from our Beach Watch surveys help show the impact of warming oceans on seabird populations. A just-released study, led by the University of Washington and published in Marine Ecology Progress Series, used data collected by community scientists from California to Alaska to understand how persistent marine heatwaves relate to seabird mortality. The results link persistently warmer ocean conditions to extraordinary seabird die-offs, showing Murres, Puffins, Auklets and Shearwaters suffered more than others.

Data collected through our Beach Watch community volunteers helped contribute to a recent publication on bottlenose dolphin range expansion. The study, published in the Aquatic Mammals Journal, used photo identification to discover that dolphins were achieving long-range movements from the Southern California Bight to the San Francisco Bay Area.

Healthy kelp forests are important for both people and nature but increasingly severe ecosystem stressors like marine heatwaves have resulted in declines in kelp in many regions, including the North Coast of California. Given the significant and sustained loss of kelp in this region, management intervention is needed to reset the ecosystem. Through this research we contributed to the largest science-based drone survey ever conducted in California to map kelp canopy cover and advance strategic kelp restoration alongside Greater Farallones National Marine Sanctuary and partners.

Jessica Morten, Greater Farallones Association staff member and Channel Islands National Marine Sanctuary affiliate, co-authored this paper assessing the reduction in underwater noise pollution from commercial shipping vessels in the Channel Islands through an incentivized vessel speed reduction program.

Marine debris is a threat to our ocean that can be more effectively addressed through monitoring and assessment of items stranded on shorelines. This study engaged citizen scientists to conduct shoreline marine debris surveys according to a published NOAA protocol within the Greater Farallones and Olympic Coast National Marine Sanctuaries on the west coast of the United States.

Kirsten Lindquist, Greater Farallones Association co-authored this paper hypothesizing that “bottom-up and top-down forces created an ‘ectothermic vise’ on forage species led to their system-wide scarcity and resulting in mass mortality of murres and many other fish, bird and mammal species in the region.”

We are proud to announce the publication of Massive Mortality of a Planktivorous Seabird in Response to a Marine Heatwave in the peer-reviewed journal Geophysical Research Letters (2018). The Beach Watch program contributed data and Greater Farallones Association program manager, Kirsten Lindquist, co-authored the paper.

We are proud to announce the publication of Ecosystem-based Management Affecting Brandt’s Cormorant Resources and Populations in the Central California Current region in the peer-reviewed journal Biological Conservation. The Beach Watch program contributed data and Greater Farallones Association program manager, Kirsten Lindquist, co-authored the paper.
