Wednesday, October 14, 2020: Biologist Bill Keener of The Marin Mammal Center, Zoom Meeting, “Tales of Urban Whales: San Francisco Bay’s Cetacean Restoration”.

Bill will present the results of the latest studies on the cetaceans (whales, dolphins and porpoises) of San Francisco Bay. The improved health of the Bay has given three species the chance to thrive: humpback whales, bottlenose dolphins and harbor porpoises. This is a good news story about how these fascinating animals have adapted to life in urban waters.

For the past four summers, an unexpected influx of humpback whales has been swimming through the Golden Gate to feed in the Bay. Meanwhile, bottlenose dolphins have expanded their range north from Southern California to become residents along the shores of San Francisco, and harbor porpoises returned to the Bay after an absence of 65 years.

Here’s your chance to learn from a local scientist about the lives of great whales, the difference between porpoises and dolphins, and what you can do to help in the study of our local marine mammals.

Duane Silverstein,, Zoom Meeting,
“Island Conservation Program”

Since 1999, Duane Silverstein has been the Executive Director of Seacology, an international non-governmental organization with the sole focus of preserving islands – their fragile habitats, vanishing species and historic cultures – throughout the globe.

Before heading Seacology, Duane was the executive director of the Goldman Fund, one of California’s largest philanthropic foundations, for 18 years. He was instrumental in creating and heading the Goldman Environmental Prize, which has been dubbed the “Nobel Prize of the Environment” by National Geographic and news media around the globe. Over his career he has visited more than 200 islands in 83 nations.

Duane has met with presidents of the U.S., Secretaries-general of the United Nations, kings, heads of state, and indigenous chiefs throughout the world on behalf of the environment. His work has been covered in media such as Time Magazine, The San Francisco Chronicle, and The New York Times. Articles he has written have appeared in over a dozen international publications.

In 2009 he was selected by a public vote as a national All-Star Among Us to be honored by Major League Baseball at the All-Star Game in St. Louis. In 2010, Duane was given the Jefferson Award for Public Service. In giving Duane a 2010 Coastal Hero Award, Sunset Magazine called him a “superhero of the deep.” In 2012, he was invited to give the closing speech on the state of the Earth’s islands for the TEDx conference in South Africa’s Cape Town. In January 2015, His Serene Highness Prince Albert II honored Duane on behalf of Seacology for outstanding innovation in a ceremony in Monaco.

Widely considered one of the world’s foremost experts on islands, he is a National Fellow of The Explorers Club and a Fellow of the Royal Geographical Society. In 2018, he accepted the United Nations Momentum For Change climate action award on behalf of Seacology. Under his leadership, Seacology was named one of the top 15 US nonprofit organizations to work for. In 2019, Duane was named a Go Blue Award Lifetime Achievement Honoree.

Duane has logged hundreds of dives in some of the world’s most exotic sites.

Amos Nachom, Big Animals, Zoom Meeting

“In Harmony with Ocean Giants: Authentic Capture of Wildlife Behavior”
He has swum with blue whales, killer whales, crocodiles, great white sharks, and anacondas in every significant body of water from the North Pole to Antarctica.
Amos’s photographic vision is to raise awareness of ocean giants in their habitats. His images reflect respect and compassion for animals and wilderness. His photographs strive to dispel the myth of “dangerous” wildlife and show harmonious interactions between man and animal. As an explorer, he leads wildlife photography expeditions through

But photographing a polar bear face to face in the open ocean had eluded him until he starred in a 2019 documentary –– “Picture of His Life” –– winner of multiple film festivals. Many club members had the pleasure of seeing this amazing film pre-COVID at the Rafael Theatre. Watch Part 1 of this Zoom presentation on Vimeo. Watch Part 2 of this Zoom presentation on Vimeo.

Ken Smith, Founder of Undercurrent
MSC hosted its first ever Zoom meeting for June vs. an in-person gathering and we were very pleased with the results. Ken Smith, editor and founder of Undercurrent, shared stories about how he:
• Became fascinated with scuba diving –– thanks to a book by Larry Clinton!
• Started what he affectionately calls “the most despised publication in the dive industry” – – a Jamaican resort that was miles from a great beach shown in a magazine story, had very little food, and no fish to see while diving
• Why he refuses to accept advertising for his monthly newsletter and annual The Travelin’ Diver’s Chapbook –– so he won’t be beholden to sponsors
• How he determined his nom de plume
• And how he chooses authors – from great reviews that divers write

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!
