Study: Nonnative Species Carried in Lakers' Ballast Water

surveillance to date. Determination of whether the collected nonindigenous species of zooplankton might be able to survive or establish in western Lake Superior waters was beyond the scope of the study.The research, conducted by The Great Waters Research Collaborative (GWRC), a project of the University of Wisconsin-Superior’s Lake Superior Research Institute (LSRI), builds on work conducted by others in the Great Lakes in recent years.The ships’ operators proposed the study as a means of complying with Minnesota Pollution Control Agency ballast water permitting requirements, and approached

in the classroom next year. And, the students from different states began their connectivity as part of this trip. They were interspersed between two boats to facilitate the budding water-quality collaborative relationships.Jake Walsh, a freshwater ecologist working as a researcher with the University of Wisconsin-Madison Center for Limnology, captained one boat. UW-Madison is the birthplace of the study of freshwater lakes, known as limnology, so it was fitting to have his expertise. Walsh's work has focused on understanding how species invasions, eutrophication, climate change and human decision-maki

How Could a ‘Sand Motor’ Help the Great Lakes?

by the waves. This tactic can protect an area for roughly 15 to 25 years. Now, the Wisconsin Sea Grant Institute is exploring whether this approach could have benefits in the Badger State.   Undergraduate research scholar Briana Shea is part of the team exploring this topic. The University of Wisconsin-Madison's Undergraduate Research Scholars program gives first- and second-year students a taste of cutting-edge research in a variety of fields. At Sea Grant, Shea is mentored by assistant director for extension David Hart. Hart’s areas of expertise include coastal hazards and community

He started his career in the U.S. before coming back to France to join CNRS in 1990. In 2000, he moved to Ecole Normale Superieure de Cachan and has been a Professor of Applied Mathematics since.  In 1984 Darryl Symonds started his career at Teledyne RD Instruments (TRDI)

biological truth: what goes in must come out. They found the invasive mussels’ sheer numbers and feeding efficiency are changing the lake’s ecosystem dynamics, and perhaps the climate, as well.   Laodong Guo and his graduate student Stephen DeVilbiss, researchers at the University of Wisconsin-Milwaukee, looked at the impacts of quagga mussels from an aquatic chemist’s point of view in a paper published this year in the Journal of Great Lakes Research. They took measurements in Lake Michigan and collected mussels from the lake. They brought the mussels into the lab to assess

he is applying to renew funding for assessing uncertainty in climate change. "Now the proposal would have to be defensible without referring to climate change explicitly, so to talk about weather risks in general," he said.   Tracey Holloway, an air quality scientist at the University of Wisconsin, said she believed simple word changes sometimes could help scientists avoid trouble. Using the term "weather" instead of "climate change," for example, could work for studies that deal with a short-term time scale, she said.   But Eric Holthaus, a meteorologist

Meteotsunamis: An Underrated Hazard in the Great Lakes

A team led by University of Wisconsin-Madison researchers has found that small, one-foot, tsunamis caused by thunderstorms (meteotsunamis) happen more than 100 times per year on the Great Lakes. Also, larger meteotsunamis of nearly three feet occur once per year on average.    The team headed by Adam Bechle, J. Phillip Keillor Fellow with the Wisconsin Coastal Management Program and Wisconsin Sea Grant, and Chin Wu, UW-Madison professor of civil and environmental engineering, analyzed 20 years of data from 32 water-level stations on the U.S. side of the Great Lakes. Most meteotsunamis

We [Heart] Actinobacteria

, that champion is a special group of actinobacteria, small microbes—like, really, really tiny —that make up a superabundant group of bacteria that’s involved in most of what goes on in the freshwater universe.   Nobody knows more about freshwater actinobacteria than University of Wisconsin-Madison professor of environmental engineering Trina McMahon. With the support of Wisconsin Sea Grant, McMahon’s laboratory members have spent the last five years studying the little critters from every imaginable angle—and in the process have become the pre-eminent experts on

First Keillor Fellow in Place: Adam Bechle

Lakes, and beyond. Along the way, he impressed colleagues and co-workers with his competence, integrity and respect for everyone he encountered, on the job and off. Keillor died rather suddenly in 2009.   Just this week, his legacy was renewed when Adam Bechle, a recent graduate of the University of Wisconsin-Madison, started work as the first J. Philip Keillor Science-Policy Fellow. Wisconsin Sea Grant and the Wisconsin Coastal Management Program created this opportunity to honor Keillor and to continue his work.   If the name Keillor rings a bell it might be because Phil Keillor also

Evinrude Fellowship Supports Environmental Research

BRP announced that its Evinrude brand, in partnership with the University of Wisconsin-Milwaukee’s School of Freshwater Sciences, has launched the BRP/Evinrude Water Research Excellence Fellowships.   The two $5,000 annual fellowships, which support tuition for graduate students at the School of Freshwater Sciences, are highly competitive and are given to students conducting outstanding research that will help protect and preserve the world’s water resources.   Recently, Evinrude also donated outboard engines to power two of the school’s research vessels.    &

PSAT Used for Trout Study on Lake Superior

most important marine mega fauna such as bluefin tuna, great white sharks and other underwater species. Recent technological advances in tagging have finally allowed for the same technology to be transferred to fresh water. The Michigan Department of Natural Resources in conjunction with the University of Wisconsin - Milwaukee and U.S. Fish and Wildlife Service has deployed a number of pop-up satellite tags to study lake trout (salvelinus namaycush) movement in Lake Superior. This is the first large scale study of any freshwater fish in Lake Superior using pop-up satellite tags and only came about
