NEW UW SEA GRANT SEDIMENT REMEDIATION GUIDE (FEBRUARY 2008)
The University of Wisconsin Sea Grant Institute has recently published a 50 page booklet titled: “Deciding About Sediment Remediation: A step-by-step guide to making the decisions by Philip Keillor, Editor.” This booklet is for those who are considering (or involved in planning) expensive clean-up of contaminated sediments.The booklet describes a step-by-step sequence of decisions to determine whether, and how, to clean up contaminated sediments, or to let natural recovery occur. More than that, the booklet summarizes the pioneering work of 26 researchers at four universities in the Great Lakes Basin; a project group who laid a foundation for numerical simulation of sediment remediation processes and cost optimization of sediment cleanup projects. The booklet is available in a paper copy (at $20 U.S.) or as a free download (.pdf document) at http://aqua.wisc.edu/publications.Click on “Contaminants” in the sidebar, on the left sidebar for this booklet and related publications, then click on the book title for a brief description, the free download, or purchase options.

DULUTH-SUPERIOR HARBOR FRESHWATER CORROSION UPDATE (SEPTEMBER 2007)
2006 Field Investigation Reports Now Online
The project study results and final investigation reports have been released and are now online. The two reports provide details and field investigation data resulting from the 2006 project field work. The first report “Final Report – Duluth Corrosion Investigation – Duluth Harbor” was completed by Altech Environmental Services, INC and focused on the collection of water quality data throughout the harbor as well as documenting the existing condition of the steel structures (Federal structure locations) using non-destructive test methods. The second report “DSPA Corrosion Investigation Report” was completed by AMI Consulting Engineers P.A. which focused on the investigations and data collections on the non-Federal structures. The two separate investigations were completed to separate the Federal structures from the non-Federal structures (due to separate funding sources) and were coordinated efforts to the total project investigation.

DULUTH-SUPERIOR HARBOR FRESHWATER CORROSION (FEBRUARY 2007)
2006 Field Investigations Completed
Utilizing project study appropriations from the State of Minnesota and the U.S. Army Corps of Engineers, the first year of field investigations into the accelerated freshwater corrosion problem in the Duluth/Super harbor were completed. The investigations focused on water quality sampling, structure cataloging and underwater inspection, corrosion product sampling, MIC studies, instantaneous corrosion rate measurements and initial coating product tests. In addition, coupons (small steel plates) were placed in the corrosion zone at several locations throughout the harbor and will be periodically sampled in subsequent years for rates of corrosion and evidence of MIC. Follow these links for detailed study information and field investigation photos.

Preliminary study results from the 2006 field investigations are currently being peer reviewed but are not yet available. Results will be posted as soon as they are released.

In 2007, the steering committee plans to continue the instantaneous corrosion rate measurements, continue the MIC studies and also initiate a series of coating tests to evaluate the use of various types of protective coatings to protect the steel from corrosion. These coating tests will focus on both the application of coating materials to existing structures as well as further testing of coatings applied to new steel before it is placed into the harbor structures.

WORKSHOP ON INNOVATIVE SHORE PROTECTION TECHNOLOGY (JULY 2006)
A workshop on innovative shore protection technology was held earlier this year (February 22-23, 2006) in Tallahassee, Florida. The workshop was organized and hosted by the Florida Department of Environmental Protection, Bureau of Beaches and Coastal Systems. The department encourages the development of new and innovative methods of solving beach erosion problems and recognizes that many new technologies exist but have insufficient information available about their effectiveness or potential impacts to beaches and other shoreline features. The workshop’s goals were: read more...

UW SEA GRANT HOSTS 2006 GREAT LAKES RIP CURRENT CONFERENCE (JUNE 2006)
The annual Great Lakes Rip Current Conference was held this year on June 6th in Manitowoc, WI at the Inn on Maritime Bay. The past several years this annual conference has been hosted by Michigan Sea Grant at various locations around Michigan. This year’s agenda included: read more...

TWO NEW GREAT LAKES COASTAL ENGINERING BOOKLETS PUBLISHED (July 2005)
Two new booklets have been recently published by Wisconsin Sea Grant and are now available. Stabilizing Coastal Slopes on the Great Lakes is a 12 page booklet providing valuable information on many of the causes of Great Lakes shoreline property slope failures and methods to improve slope stability. Working with Engineers and Contractors on Shore Protection Projects is a four page booklet which provides information for shoreline property owners on how to select and work with shore protection design professionals and contractors. Both booklets are free of charge from Wisconsin Sea Grant and can be obtained by going to http://aqua.wisc.edu/publications.
