Friday Fish Fry? Try the Great Lakes Whitefish

In Wisconsin we know that there aren't too many things better on a Friday than a tasty fish fry. Restaurants all over the state do a booming business serving up fried fish on Friday evenings. Of course there is a bit of history behind the fish fry tradition that you can read about here from UW-Madison folklorist Dr. Janet Gilmore, but what about starting your own family fish fry tradition at home?

Recently published by Michigan Sea Grant, "Wild Caught and Close to Home: Selecting and Preparing Great Lakes Whitefish" offers more than 50 recipes from credentialed chefs and whitefish specialists to help you get started making your own fish at home. For those who are interested in healthier options than frying, it also offers ideas for steaming, poaching, smoking, grilling and pickling, to name a few. It also offers a brief history of whitefish.

The Water Library is acquiring this book,  but if you just can't wait, check out these other books we have to offer on preparing fish. You can check this website for further information on Great Lakes whitefish.

Tsunami Science

Featuring the USGS Tsunami specialist and a clip from NOAA, this quick and informative news video explains the science behind tsunamis. Some important factors include distance from the sea-floor earthquake as well as the topography of the area. The tsunami is caused by an underwater earthquake that forces the ocean floor upward and forcefully pushes the water out of the way, causing it to slam into the shore. The tsunami continues as a series of waves resulting from that undersea earthquake. The waves can be very long lasting and can travel thousands of miles, only stopping from direct impact with a land mass. NOAA and the USGS use monitoring devices to keep track of tsunami activity globally, including near the northern California coast where previous damages have been caused by tsunamis.

For further information about tsunamis, see the NOAA tsunami website. To read about some of the research that is taking place dealing with tsunamis and earthquakes, check this USGS page. The Water Library also has a few tsunami titles for adults and children, please contact us if you are interested in checking these out.

No, not PCBs, PBDEs!

PBDEs is the quick way to refer to polybrominated diphenyl ethers, toxic compounds used in manufacturing as flame retardants. Common household items that are routinely flame retarded include mattresses, television sets and computers. Since PBDEs have been identified in nature, researchers in UW-Madison's Department of Forest and Wildlife Ecology have been doing some interesting work to see what the implications may be, specifically on the Northern Leopard Frog. This UW Sea Grant video will give you a closer look.

National Groundwater Awareness Week

The Center for Watershed Science and Education has written four news releases in cooperation with the Wisconsin Water Resources Institute (WRI) for National Groundwater Awareness Week. The Center is part of the University of Wisconsin - Extension Cooperative Extension Service and housed in the College of Natural Resources (CNR) at UW-Stevens Point. Specifically, the Central Wisconsin Groundwater Center works with citizens and local governments throughout Wisconsin, particularly those in the central part of the state. Their website host a variety of resources that provide helpful information about groundwater issues.

This year National Groundwater Awareness week is taking place March 6th through March 12th. Raising awareness of groundwater, water beneath the earth's surface, is important because it is essential to the health and well being of humanity and the environment. In Wisconsin, groundwater provides drinking water for 70% of Wisconsin residents and 95% of communities. It also benefits lakes, streams and wetlands and helps sustain the many creatures who live there. Read the four news releases for further information.

Think Spring, Think Gardening

Two increasingly popular gardening methods are green gardening and rain gardens. While benefiting the environment in several ways, these two types of gardens also yield healthy plants and vegetables and beautiful flowers.

Sometimes also referred to as organic gardening, green gardening saves soils and nearby water systems from the trauma of the chemicals and pesticides or fertilizers which are often used in traditional gardening. For some suggestions or tips, see our recommended reading list on green gardening.

A second kind of environmentally friendly garden is a rain garden. These gardens satisfy the dual purpose of growing pretty flowers and plants while also filtering potentially harmful runoff from getting into the watershed. One local rain garden is in Cross Plains at the Rosemary Garfoot Public Library, Wisconsin's first green library. For information on how to start your own rain garden, see our recommended reading list on rain gardens.

"The Next Step in your Carpucation"

With the coming of spring also comes National Invasive Species Awareness Week, the first week of March. Staff at the Aquatic Sciences Center have taken this opportunity to educate people a bit about the ever-unpopular asian carp. An introduction to asian carp can be read in this previous blog entry. For those who are more familiar with the species, this UW Sea Grant release helps to explain information as relayed by invasive species outreach specialist Phil Moy.

Entitled "Taking Five With an Asian Carp," this article offers information relating to five surprising facts about the species. Are asian carp really bottom feeders? Do they relate to algal blooms in any way? What about those zebra mussels and quagga, is there a connection between them and asian carp? How many types of asian carp are really out there? These are all questions answered in the press release. For further reading on invasive species, see the library's recommended reading list.

Hydrofracking leaves water radioactive?

There is concern in Pennsylvania that some wastewater is not being properly treated and, as a result, this toxic water may be mixing with drinking water sources. This is the result of a process commonly refered to as hydrofracking. More formally known as high-volume horizontal hydraulic fracturing, this relatively new type of drilling is being used to access natural gas which exists as bubbles in deep layers of rock beneath the earth's surface. This process involves blasting the rock with high pressure water which contains a combination of sand and chemicals. While some of these chemicals do occur naturally, they do not normally mix with drinking water. This is where there is a foreseen problem.

After blasting, the wastewater is treated by sewage or other wastewater treatment plants, but data has been gathered showing that the process of cleaning the water there leaves the water with levels of toxins higher than what was previously known. After being treated the water then mixes with other waters and may eventually be getting into the drinking water supply. The issue is under review while arguments are being raised about the level of testing to which the waters are subjected. The New York Times article has more on the story.
