October 7 roundtable about THORR, which maps river temperatures from space

The Salish Sea Science Roundtable online speaker series continues on Tuesday, October 7 from 12:30 – 1:30 pm.

The University of Washington’s Thermal History of Regulated Rivers (THORR) tool transforms NASA’s Landsat satellite imagery into current and historical river temperature insights. Learn how advanced data-driven techniques enable accessible mapping of water temperatures across remote streams—vital for salmon survival. This open-source platform can provide managers with actionable information to support dam operations, habitat restoration, and climate adaptation planning. For example, the Columbia River Inter-Tribal Fish Commission is applying these insights to improve riverine water management towards fish abundance, illustrating THORR’s broader potential to guide sustainable water and fisheries decisions.

Roundtables occur virtually on the first Tuesday of each month as a way to share emerging science that is shaping Salish Sea ecosystem recovery.

This event is free, but registration is required.
