Sidney Carste

Sydney grew up along the Pacific Ring of Fire in Seattle, Washington, where early exposure to volcanoes and glaciated landscapes sparked a deep curiosity about the science behind Earth's dramatic features. This interest led her to study Earth Systems Science at university; a geology-adjacent field that emphasizes the math and physics of plate tectonics over the chemistry of rock identification. Her favorite topics to explore and discuss are physical geomorphology and large-scale tectonic processes. Sydney's research experience spans a range of topics, from long-term climate change projections on the water cycle to statistical modeling of avalanche runout zones in southern Chile with the Chilean Antarctic Institute.

She entered the expedition industry three years ago, a move that has allowed her to stay immersed in scientific inquiry while spending time in the field, conducting citizen science with guests, and connecting with people from around the world. On board, she lectures primarily on geology and glaciology, but also finds time to share insights into oceanography, weather, and astronomy. Her current passion project involves digitally tracking icebergs and sea ice extent across both the Arctic and Antarctic. When not at sea, Sydney can be found exploring the western U.S. by bike or on foot. Be sure to say hello during the voyage- especially if you want to talk about anything related to the non-living Earth!
