Photographer, filmmaker, former NASA researcher, bird expert and Lopezian Peter Cavanagh will present a photographic journey of a voyage along the Scotia Arc to Antarctica on Wednesday, May 15, 7 p.m. at the Sea View Theatre in Eastsound.

Come learn more about the vast polar desert, its amazing wildlife and how changes in climate there impact the San Juan Islands locally and globally.

Cavanagh and the voyagers stopped in several of the Falkland Islands and made landings on penguin-packed beaches in the wildlife paradise of South Georgia Island. An eventful passage across the Scotia Sea opened up vistas of massive icebergs, snowcapped mountains rising from the ocean and colonies of Adélie and chinstrap penguins. Recent changes in climate and krill harvesting raise the question of how many more generations will be able to enjoy this vast polar desert in its current abundance. Cavanagh is a Pacific Northwest photographer who specializes in photographing birds in flight.
