Small Mussels with Big Effects: Invasive Quagga Mussels Eat Away at Great Lakes Food Web

Anonym 0 32975

Since hitching unsolicited rides in boat ballast water in the late 1980s, invasive quagga mussels (Dreissena rostriformis bugensis), which are native to Ukraine, have caused massive changes to the ecology of the Great Lakes.  These invasive mussels have also taken a toll on the Great Lakes recreational and commercial fisheries, which are valued at $4-7 million annually.

Hydrologic Dashboard Tool Washes Out Storm Uncertainties

Inspiration struck with the large storm that hit Duluth, Minnesota in October of 2005. The flooding that ensued after this unexpected event caught many off guard, so University of Wisconsin Sea Grant’s David Hart hired several graduate students to create an online tool that would show where and how the storm affected the area, and provide insight to similar events in the future.

Michigan Sea Grant Oversees Successful Habitat Reconstruction

Michigan Sea Grant is overseeing a long-term restoration project to restore fish spawning habitat for native fish species. An acre of rock reefs were constructed in the Middle Channel of the St. Clair River in the spring of 2012 — and fish are already using the reefs.  “It is science in action,” said Jennifer Read, assistant director of Michigan Sea Grant and project lead. “We were still constructing reefs a few hundred feet away, and yet, here they were…”

Drifting Buoys Track Water Currents in the Great Lakes Straits of Mackinac

When you’re watching a river or the waves on a lake, do you ever wonder where that water goes? If you threw a rubber ducky into the water, where would it end up? Scientists are studying the movement of water in the Straits of Mackinac, which connect Lake Michigan and Lake Huron, to figure out how the water moves around. This water movement can affect ship traffic, how pollution spreads, and where aquatic animals go.

This summer, NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) hosted 10 interns, ranging from a high school senior to graduate students well on their way to their Ph.D. degrees. Each intern conducted research relevant to GFDL’s climate-science mission, and most presented their findings at GFDL and at their home institutions.

What’s the first thing that comes to mind when you hear the words carbon dioxide? Is it the ocean? In this day and age, it should be. The ocean absorbs about one fourth of the extra carbon dioxide in the air that is released through human activity, according to a researcher at Scripps Institution of Oceanography.

Phytoplankton - tiny plant-like organisms drifting through the great, vast ocean - are barely visible to the naked eye, and some are visible only through a microscope. Yet, when they are thriving, it is possible to see them from as far away as space. Their location is marked by swirling patterns of bright blues and greens that give the ocean a slick, marbled appearance, like oil on water.
