IVER 3, Michigan Tech’s new Autonomous Underwater Vehicle (AUV) arrived at the GLRC on Saturday, September 7. It’s first debut into the Keweenaw waterway is happening today (Sept 10).
The IVER 3 was manufactured by Ocean Server Technology, Inc. in Fall River, MA, and represents a new generation of far more advanced and capable AUV’s for underwater exploration and research. Once a mission is programmed, the AUV executes that mission ( 8 – 12 hours in duration) with no human intervention.

Norm Yan of York University, Ontario, Canada is visiting Michigan Tech, presenting seminars and working on collaborations. On Monday September 9th , he presented “Regulators of recovery of acid and metal-contaminated lakes in Sudbury, Canada” for the Environmental Engineering Seminar Series. He also will present another seminar, 2:00pm Friday, September 13 in Dow 642 entitled “The widespread threat of calcium decline in Canadian Shield lakes.”
Norman Yan’s long-term professional goal is to understand the impacts of multiple environmental stressors on the biota, particularly the animal plankton, of Canadian Shield lakes. He completed his Master’s degree at the University of Toronto on the effects of acid rain on phytoplankton, and his doctoral degree at University of Guelph on the factors regulating the accumulation of toxic metals in zooplankton. After working for the Ontario Ministry of the Environment for 25 years, Yan joined York University in Toronto in 2000, and he now splits his time between the university and the Ontario Ministry of the Environment’s Dorset Environmental Science Centre. Yan’s current areas of research are: 1) determining the individual and joint impacts on lake ecosystems of invading predators, and changes in climate, metals, acidity, calcium and nutrients; and 2) quantifying the regulators of recovery of lakes from past environmental damage. Yan has authored or co-authored over 200 publications, a body of work that has been acknowledged with both provincial and national awards of excellence in fundamental and applied research on Canadian lakes. In 2012, he was inducted as a Fellow into the Royal Society of Canada.
Aparupa Sengupta, a PhD student in biological sciences, took third place for her oral presentation “Using a Biological Remediation System to Address Antibiotic Contamination in Aquatic Sources” at the International Conference on Medical Geology Annual Meeting 2013, held Aug. 25-29 in Arlington, Va. She was selected from among 30-35 student presenters from around the world. Sengupta received a certificate, a book and $100 prize. Her coauthors were Adjunct Professor Dibyendu Sarkar and her advisors, Professor Emerita Susan Bagley and Associate Professor Rupali Datta (Bio Sci).
The Slocum Glider, owned by the University of Minnesota-Duluth (UMD), was brought to the GLRC by Dr. Jay Austin for extended times to follow the Ranger III route across Lake Superior from the North entry to Isle Royale. A 13-day mission resulted in 2 round trips to Isle Royale where the glider gathered profile data of the water from the surface to the lake bottom. A second 5-day mission was a single round trip across the same route. The data gathered by the glider will complement data gathered by instrumentation on the Ranger III on every trip it makes to Isle Royale.
The glider is programmed to move vertically as well as horizontally in the water to collect profile data. When the glider periodically surfaced, it transmitted data back to the operations computer, so researchers could monitor its progress. At the end of each mission, the glider surfaced and transmitted its current location coordinates to the pick-up crew on the S/V Polar for retrieval. This is the beginning of a great collaboration between the GLRC and the Large Lakes Observatory at UM-D.
The R/V Agassiz has had a record number of launch days scheduled for summer and fall 2013. Over 70 days have been scheduled out on the water for research, outreach, and course lab work. Researchers include Drs. Mouw, Fahnenstiel, Kerfoot, and Urban. Outreach activities include community and K-12 class tours and the GM Ride the Waves program with Joan Chadde, Rob Handler, and Dr. M. Auer. Drs. Urban, Marcarelli, and Rose have scheduled the R/V Agassiz for lab courses and field trips.
The National Oceanic and Atmospheric Administration (NOAA) visited the GLRC with the R/V Storm for 2 weeks in August, with another opportunity for Michigan Tech researchers to take advantage of longer excursions into the Great Lakes. Drs. Gary Fahnenstiel and Colleen Mouw began a long-term water quality-monitoring program with trips in northern Lake Superior towards Canada. Charlie Kerfoot was able to expand his sampling in the Buffalo Reef near the Gay shore. Dr. Kerfoot was able to position the R/V Storm and the R/V Agassiz in the same vicinity at the same time, and was able to use a Remotely Operated underwater Vehicle (ROV) to obtain video coverage of the Gay stamp sands encroaching on Buffalo Reef.
June 23-30, 2013
The United States Geological Survey (USGS) visited the GLRC with the R/V Sturgeon for a week in June, giving Michigan Tech researchers the opportunity to conduct overnight sampling trips, and to explore the possibilities of extended boat time that has currently been restricted to single day excursions with the facilities on the R/V Agassiz. Nancy Auer was able to perform some night time research, and the R/V Sturgeon also assisted in some work on the instrumented buoys located near the North and South entries into Lake Superior.
The Great Lakes Research Center (GLRC), along with weather service researchers, is set to wrap up a study of dangerous near-shore currents. Chief among their concerns: how to predict dangerous currents, and how to keep the public safe—especially along the many miles of Michigan’s shorelines.
Guy Meadows, GLRC director, hopes to soon be able to accurately forecast dangerous near-shore currents and know where (and when) they will be present. Michigan Tech researchers are using special radar technology developed at MTRI to track how waves move toward shore and to map the lake floor.
The final phase of the in-water portion of the research project will take place along Lake Michigan’s north coast in mid-Sept.
As the next wave of hot temperatures roll into the region, GLRC researchers and Jamie Racklyeft, of the Michigan Sea Grant, urge swimmers to keep safety in mind. Raising awareness of the threat of dangerous near-shore currents is the first step toward swimmer safety.
