Research

A collaboration between NMU and NASA began this week. Contractors are transporting instruments to Granite Island to set up an offshore solar radiation-monitoring site for NASA’s Clouds and the Earth’s Radiant Energy System (CERES) experiment. CERES has been measuring Earth’s radiation via satellite for more than 30 years. In an effort to validate that data through ground measures—ideally over water, far from land contamination—NASA selected a Lake Superior location after decommissioning a previous Chesapeake Bay site because of safety issues. The goal is that analyses of  CERES data will lead to a better understanding of the role of clouds and the energy cycle in global climate change.

Two NMU biology master's degree candidates will attend the 2018 International Charr Symposium June 18-21 in Duluth. They are among four students being sponsored by the Greater Lake Superior Foundation. Grace Zimmerman's research statement indicates she is "looking at the influence of food availability and temperature on individual differences in metabolic rate in brook trout (Salvelinus fontinalis)." Jacob Bowman is focusing on "how the metabolic physiology of individual brook trout determines their life history characteristics, including migration and movement within streams.”

Two NMU students and two alumni comprise Four the Water, a group circumnavigating Lake Superior by kayak to raise awareness of the importance of clean water and funding for nonprofits that protect the Great Lakes. The friends reported on Facebook meeting friendly and interesting people in their first week, including a “wonderful gentleman who shared many stories with us about life on Au Train Island since the late ‘70s, including his pet wolf (not really his pet, but he has one on the island).” There was also Ben, “who taught us how he nets fish as he is a Chippewa Native, allowing us to hop on his canoe.” They will make a documentary about their journey and hope to screen it at film festivals in the Great Lakes region.
