Thomas Haine 

Alaska's Glaciers and the Inside Passage

August 15 - 22, 2026

Thomas Haine is a professor in the Department of Earth & Planetary Sciences and a student of ocean circulation, ocean dynamics, and the ocean’s role in climate. Tom studies and teaches oceanography and climate sciences, especially ocean circulation and dynamics, and the ocean’s role in Earth’s climate. His main research interests are in the circulation of the high latitude oceans, including the Arctic and sub-Arctic Oceans. His approaches are computational and theoretical, although he collaborates with observational oceanographers and has participated in twelve research expeditions. He coauthored a textbook, entitled Ocean Circulation in Three Dimensions (2019, Cambridge University Press), and he’s working on another textbook, entitled Conceptual Modeling in Earth and Planetary Sciences.

Kevin Lewis 

Solar Eclipse Cruise and Expeditions to Antarctica 

August 6 - 15, 2026 and January 5 - 18, 2027

Kevin Lewis is the Morton K. Blaustein vice chair and professor in the Department of Earth and Planetary Sciences. Lewis’s research focuses on problems in planetary geophysics, from the scale of a grain of sand all the way up to the crust of a planet. He has worked in depth on the nature of sedimentary rocks of Mars, and what they might record about that planet's past climate and habitability. He is also interested in understanding the large-scale properties of planetary lithospheres using magnetic, gravity, and topography data sets.
