Inspired by Women in Ocean Science
Shark Stewards is honoring women in ocean science during Women’s History Month by featuring stories shared by women on our team. A majority of our membership and leadership team are women (and many are scientists!), so we are hosting a series of guest essays contributed by volunteers all month. Last week’s article by Justyne Triest honored Valerie Taylor, the latest is by Molly Yoon on “Her Deepness” Dr. Sylvia Earle and Hope Spots.

#SharkWatch: New Study on Soupfin Sharks
A new study by Dr. Andrew Nosal, a shark scientist at Scripps Institution of Oceanography and a professor at the University of San Diego found that every three years the same soupfin sharks return to La Jolla shores. In a 7-year long study, Nosal and the Scripps team have found that the same soupfin sharks, identified through acoustic tagging, return to the cove every 3 years. Some females, carrying 40 to 50 pups return to the protected shallows to gestate and forage.
In the 1940s and 50s the CA soupfin shark population was nearly eradicated for their large livers which are rich with vitamin A and an oil called squalene in a practice termed “livering”. Since the synthesis of vitamin A, the soupfin sharks and sevengill sharks are no longer targeted commercially. Listed by the IUCN as Critically Endangered globally, these sharks are benefitting from our MPAs. However, these and other sharks are caught by sports fishermen along the coast and in the pupping grounds of the San Francisco Bay.
Since 2016 Shark stewards has been collecting data on California recreational shark catch and dive observations in a project called Shark Watch. Learn how you can be involved

Dive Into California MPAS
Join our growing network of citizen scientist divers making and sharing observations of plants, animals, and seaweeds in our California Marine Protected Areas (MPAs) using the iNaturalist app. Check our event schedule including the upcoming Snapshot Cal Coast with the California Academy of Sciences and the Department of Fish and Wildlife, dive in and make your own observations! Data collected will be used for better management and research including trends of species affected by climate change and other human impacts.
