Measuring Convection Cycles in Lake Superior

Ecology and Environment

The Large Lakes Observatory at UM Duluth has had a huge mooring in Lake Superior for the past couple of months. The structure, nearly 1,000 feet wide and 500 feet tall, was designed to collect data about the convection cycle in the lake. The research team removed the structure earlier this month. An article about the project appears in the Duluth News Tribune: One-of-a-Kind Structure Extracted From Lake Superior.

MSI PI Jay Austin (professor and head, Physics and Astronomy, UM Duluth) is the principal investigator on the project. Professor Austin uses MSI for two projects: one examines lake thermal structure and ice formation, and the other is developing a modeling framework for the St. Louis Estuary/Duluth Harbor/Lake Superior coupled system and a hydrodynamic modeling platform within which to study circulation, thermal structure, and the interaction of these bodies of water.
