Twin Ports Freshwater Folk: A Framework for an Early Warning System for the Great Lakes

University of Minnesota Duluth Natural Resources Research Institute (NRRI) Senior Research Fellow Lucinda Johnson will give a presentation on the framework developed by the International Joint Commission's Great Lakes Science Advisory Board for an early warning system for the Great Lakes.

Lucinda’s presentation will be part of Minnesota Sea Grant’s November 2023 Twin Ports Freshwater Folk (TPFF) event on November 1, 2023. This will be a hybrid event with in-person and virtual options to attend. Sub sandwiches and water will be provided at the in-person portion of this event.

TPFF is an informal gathering of people from the Twin Ports of Duluth, Minnesota and Superior, Wisconsin, who are engaged in freshwater research, policy, or regulation issues, for networking, informal discussion, and a seminar.
