Tristin McHugh, North Coast Regional Manager with Reef Check, will present “Phase Shift from Kelp Forest to Urchin Barren Along California’s North Coast”.

As a kid, Tristin, MS, UC Santa Cruz, was always knee deep in some water system. Becoming a scientific diver helped her find a niche in studying the underwater environment and changed her life.

“The idea of protecting such an invaluable resource, kelp forest ecosystems, by using research divers and technicians filled me with admiration for the marine science field and those who were so deeply engrossed in the conservation efforts,” she said.

Founded in 1996 by marine ecologist Dr. Gregor Hodgson, the Reef Check Foundation is a global NPO dedicated to conserving two ecosystems: tropical coral reefs and California nearshore rocky reefs and kelp forests. Volunteer today, visit or email

Todd Steiner, “A Protected Superhighway for Turtles and Sharks”.  Meeting at Book Passage, Corte Madera.

Galapagos Islands, the inspiration for Darwin’s Theory of Evolution, and Cocos Island, a place so amazing that Jacques Cousteau called it the “most beautiful island in the world”, have some of the highest underwater shark biomass ever recorded.

The marine fauna at these two International Biosphere Reserves also include highly endangered migratory species such as scalloped hammerhead sharks and leatherback sea turtles. Recent research indicates movement of these species between the islands, and once outside the marine reserves, they are not afforded protection from fishery pressures.

His lecture will introduce you to Cocos Island’s underwater wildlife, the political initiatives to create the first “swimway” for highly migratory marine species connecting the National Parks of two nations, and how you can help, including as a volunteer scientist on a Cocos Island research expedition!

Dr. Cynthia Catton, “Causes and Consequences of
Large-Scale Bull Kelp Loss in Northern California”.

Dr. Cynthia Catton is an Environmental Scientist based in the Bodega Bay field office at the UC Davis Bodega Marine Laboratory. She’s studied California kelp forest ecology and abalone population dynamics for more than 15 years.

She’s currently spearheading a large collaborative effort to support the recovery of the bull kelp forests in Northern California.

These underwater forests have declined by more than 90% of historic abundance due to environmental and ecological stressors. The consequences? They’ve been devastating to coastal communities that rely on strong tourism and on fisheries. Dr. Catton will describe the series of events that have led to the current ecological crisis and the collaborative efforts underway to support the kelp forests’ recovery.

Marin Scuba Club Presentation: Banco Chinchorro, Mexican Mayan Riviera.
Join us at our June meeting as a cadre of Marin Scuba Club divers join forces to present videos and images from an October 2017 journey to the warm waters of Banco Chinchorro on the Mexican Mayan Riviera near the Belize border.

“Fourteen club members visited Banco Chinchorro for the first time in October,” said Barb Wambach, MSC Activities Coordinator. “The most exciting diving was the banc, a one-hour ride from Mahaual, Mexico,” she added. “The wrecks on the outer side of the reef were the best that I’d ever visited –– laying in 25-35 feet of clear water, abundant with sea life and extremely colorful. The banc also featured large animals: leatherback turtles, eagle rays, stingrays, nurse sharks and reef sharks, as well as approximately 500 American crocodiles.

If you have some videos or images to share with the Club, please get them to Barb ASAP.
