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.

Join us for an evening with award-winning wildlife photographer, Jodi Frediani who introduces us to Svalbard, a Norwegian archipelago located north of the Arctic Circle, not far from the North Pole. 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.
