California humpback whales are seasonal migrants between here and mostly Mexico and Central America, a simple general pattern, but when we look deeper the patterns are complex and persistent across huge population changes. Join us for an exploration of new technology enabling a deep dive into the lives of leviathans, and the understanding recently revealed. We are delighted to have Ted Cheeseman, founder of Happywhale share insights from his unique vantage point and knowledge.

The federal government budget at NOAA has been slashed. What does this mean for our Nation's most significant marine areas and the wildlife they protect?  Please join us as we hear from Maria Brown, former Superintendent of the Greater Farallones and Cordell Bank National Marine Sanctuaries. Come to learn about our local National Marine Sanctuaries, some of the most biologically diverse marine ecosystems in the world. How do cetaceans depend on these marine protected areas? What exactly are the regulations and what projects are underway meant to restore cetacean populations? Importantly, how can we all help safeguard these vital habitats? If there was ever a time to be better informed of marine policy and protection, it is now!

We turn our attention to the leviathans of our seas, of our planet, the blue whale. In this talk, marine mammal biologist and recipient of our chapter’s recent research grant, Jessie Meyer will share his study results. As a measure of health, body condition has been increasingly used to assess the impacts of environmental and physiological change on marine mammals. This study expanded a previous analysis of blue whale body condition in the Eastern North Pacific (ENP) using images collected by Cascadia Research Collective (CRC) over a total of 21 years between 1991 and 2023. In all, 4,188 images of 1,319 individuals were grouped by year, decade, region, and season to investigate potential differences in body condition. Please join us for ground-breaking knowledge and insight into these wondrous animals who command our respect and caring.

Once numbering in the tens of thousands, the North Pacific right whale was driven to the brink of extinction; now it's estimated that fewer than 50 animals remain in the eastern population. Despite this, one of these rare animals was seen this May off Point Reyes, CA. So how do you study the proverbial needle in a very large haystack? Come learn about North Pacific right whales as Jessica Crance, Marine Mammal biologist and right whale specialist, talks about their dark history, the research being done to save them, and the struggles and rewards of studying one of the most critically endangered large whale populations in the world.

Dr. Nicola Ransome is the recipient of ACS-SF Bay chapter’s 2023 Christine Fitzsimmons cetacean research grant. Her primary research focus is on the study of anthropogenic impacts on large whales of the Eastern Tropical Pacific. She has used the grant proceeds toward her ongoing research of a threatened “distinct population segment” (DPS) of humpback whales, whose migratory corridor is Central America through the west coast of North America. The research is focused on seasonal (early season) timing and identification of the whales through tail flukes and the Happywhale identification platform. Please join us as Nico shares her findings and the impact of the results from this empirical research.

This cluster of islands is home to polar bears, walruses, reindeer, and arctic foxes, and provides breeding and nesting grounds for thousands of seabirds. Ice covers more than 60% of the land mass, and the remaining tundra, grass, and moss-covered plains slope up toward perilous, high, ragged cliffs. Towering mountain peaks rise dramatically, surrounded by glaciers of blue and black ice. And the Arctic Ocean bathes them all.
