Happy Birthday Detroit: The 313 Turns 313 Years Old!

The city of Detroit and the Detroit River have experienced a great deal of environmental change in the last 313 years. Then, like now, it’s impassioned citizens and groups that work to help make the city and the river great.

Early Detroit

On July 24, 1701, Antoine Laumet de LaMothe Cadillac established the City of Detroit with permission from French King Louis XIV. When first established, the French trading outpost was called Fort-Pontchartrain du Détroit. Today, some of us who live in metro Detroit often refer to the city by its area code, 313. While much has changed in the last 313 years, some things are still very similar. Detroit is still a place with impassioned people who are working hard to make Detroit a great place to live, work and play.

Take a Great Lakes Class at the U-M Biological Station

The University of Michigan Biological Station (UMBS) offers adults the chance to be students again! Participants may sign up for one of three mini-courses: Art in Nature, Fungi or Great Lakes Oceanography. Each class runs from Wednesday through Sunday, Aug. 20-24.

  • Great Lakes Oceanography is a rare opportunity to learn about water quality, invasive species and Great Lakes ecology from three entertaining and enthusiastic experts. Gary Fahnenstiel, Tom Nalepa and Dave Schwab will teach the class on board NOAA Research Vessel Laurentian. All three men are Scientists Emeriti from the National Oceanic and Atmospheric Administration who are currently staff at the University of Michigan Water Center. Their respective areas of study are aquatic biology, invasive species, and hydrodynamics. Class participants will visit several locations in Lake Huron and the Mackinaw Straits. Along the way, they will use equipment and presentations from Fahnenstiel, Nalepa and Schwab to study the health of our region’s most vital natural resource.
  • Art in Nature is for visual artists at any skill level. Instructor Ann Singsaas will provide demonstrations and inspiration in plein-air sketching, simple watercolor painting techniques, and the elements of design. Students will learn to keep a field sketchbook, take visual notes and capture both the detail and the broader essence of the natural world on paper. Working on location and in the studio, students will learn to sketch or paint with minimal equipment, providing a new way to document travels. Singsaas has degrees in both biology and art and advanced study in painting. She shows her artwork in the Midwest is represented by several galleries in Wisconsin.
  • Fungi provides an in-depth look at nature’s recyclers. Local teacher and guide Marilynn Smith will use lectures and field trips to teach the structure, reproduction and ecology of fungi. Participants will also learn about the many uses humans have for fungi, beyond food. Smith has used her graduate training in mycology in the education and medical fields.

Course participants may commute or live at the Station, located on Douglas Lake, and eat in the  dining hall.

“Our mini-courses provide people from across age groups wonderful opportunities to experience ‘North Woods’ environments and biota from new and interesting perspectives,” says UMBS Director Knute Nadelhoffer.

Lake Erie Harmful Algal Bloom Forecast for 2014

NOAA and its research partners predict that western Lake Erie will have a significant bloom of cyanobacteria, a toxic blue-green algae, during the 2014 bloom season in late summer. However, the predicted bloom is expected to be smaller than last year’s intense bloom, and considerably less than the record-setting 2011 bloom. Bloom impacts will vary across the lake’s western basin and are classified by an estimate of both its concentration and how far it spreads.

Harmful algal blooms (HABs) were common in western Lake Erie between the 1960s and 1980s. After a lapse of nearly 20 years, blooms have been steadily increasing over the past decade. Since 2008, NOAA has issued weekly HAB bulletins for western Lake Erie through the National Centers for Coastal Ocean Science (NCCOS) to give warnings of bloom development. Also, this marks the third time NOAA has issued an annual outlook for western Lake Erie.

Special Funding Opportunity: Lake Michigan Food Web RFP

The Illinois-Indiana and Michigan Sea Grant programs have launched a joint call for small research projects related to Lake Michigan food webs. During the Great Lakes Regional Research Information Network – Lake Michigan food web workshops, participants identified data gaps and research priorities to help understand changes to Lake Michigan food webs.

Details at a glance:

  • Researchers may request up to $50,000 of federal (Sea Grant) funds and must demonstrate at least 50 percent match.
  • Funding will be provided for one year beginning February 1, 2015, or the date of the award, and projects should be completed by March 1, 2016.
  • We anticipate funding 2-4 Illinois/Indiana-based projects and 1 Michigan-based project.
  • Letters of intent should be submitted by July 18, 2014, with full proposals due on August 11, 2014.
  • See: Full RFP

Research projects that explore the following will be given priority:

  • The microbial food web, including responses of higher trophic levels to the microbial food web.
  • Nutrient transfer nearshore-to-offshore (and offshore-to-nearshore) by physical processes and/or organism movement (e.g., fish).
  • Food web differences across Lake Michigan regions or habitats (e.g., rocky vs. sandy substrate, relative importance of nearshore habitat to broader lake processes).
  • Relative importance of different carbon or phosphorus sources to the food web (e.g. picoplankton, bacteria, Cladophora).

Field sampling for proposed projects should take place during the 2015 season in conjunction with the Cooperative Science and Monitoring Initiative (CSMI) field year on Lake Michigan. To best integrate the results from these projects with broader sampling efforts, proposed projects must demonstrate plans for collaboration with at least one federal agency participating in CSMI sampling.

For example, collaboration could be: requesting time on research vessels in order to complete proposed sampling; conducting sampling at the same or complementary spatial locations; conducting sampling at similar times of year; and/or ensuring that laboratory or modeling studies will complement field efforts.

Boosting Native Fish in St. Clair River

July 1, 2014

ANN ARBOR– Construction of two new fish-spawning reefs is about to begin in the St. Clair River northeast of Detroit, the latest chapter in a decade-plus effort to restore native species such as lake sturgeon, walleye and lake whitefish.

The new reefs will be built this summer and fall at two locations on the St. Clair. The goal of the University of Michigan-led project is to boost fish populations by providing river-bottom rock structures suitable for spawning.

The crevice-filled rock beds are designed to mimic the natural limestone reefs that existed before the rivers connecting lakes Huron and Erie were dredged and blasted to create shipping canals, and before an increased flow of sediments into the system from agricultural and urban runoff.

Construction of the Harts Light Reef is scheduled to begin this week and is expected to last eight to 12 weeks. The site is adjacent to East China, between St. Clair and Marine City. Work at the Pointe Aux Chenes site, which is between Algonac and Russell Island, will likely begin in September and is expected to last six to eight weeks.

The $3.5 million project is funded by the federal Great Lakes Restoration Initiative and is a follow-up to rock reefs built in the Detroit and St. Clair rivers in 2004, 2008 and 2012. The habitat-restoration project is led by U-M in collaboration with various local, state, federal and private partners.

Over the years, the reef builders have experimented with rocks of different type, shape and size. They discovered that the location of the reef within the river channel is more important than the kind of rock.

Deep, swift-flowing waters seem to work best, tempting the target fish species while keeping the rocks free of silt, algae and mussels. Also, the rocks must be piled deep enough to form crevices that protect eggs from being washed downstream or consumed by predator fish.

The reefs built in the Middle Channel of the St. Clair River in 2012 have attracted spawning lake sturgeon for two consecutive years, an indication that the reef builders have hit upon the right recipe, said project leader Jennifer Read, deputy director of the U-M Water Center at the Graham Sustainability Institute.

“These fish seek out rocky areas in clean, fast-flowing water. Unfortunately, most of that habitat type was removed when the shipping channels were created or has filled with silt from agriculture and construction in the watershed. But we’re gradually restoring it with these reefs,” Read said.

“A long-term goal of this team is to create enough fish-spawning habitat in the river so that we have really robust, self-sustaining populations of lake sturgeon, whitefish and walleye,” she said.

The latest spawning reefs will be made from broken limestone blocks 4 to 8 inches in diameter. That size seems to entice native fish while discouraging invasive species such as the sea lamprey and the round goby.

The limestone is from quarries in Bay Port and Ottawa Lake, Mich., and a crane with a GPS-guided clamshell shovel will precisely position the blocks on the river bottom. The work is being done by Faust Corp., a marine construction firm, along with SmithGroup JJR engineers and architects.

Both sets of reefs will be located in 30- to 50-foot waters and will not interfere with personal boats or freighters and will have no detectable effect on water flow or water levels.

The Harts Light Reef will be 3.8 acres: 1,007 feet long, 165 feet wide and 2 feet tall. The Pointe Aux Chenes Reef will be 1.5 acres: 605 feet long, 108 feet wide and 2 feet tall.

The lake sturgeon is the biggest fish in the Great Lakes, and the St. Clair River is home to the largest remaining population in those inland seas. They are classified as threatened or endangered in seven of the eight Great Lakes states.

Lake sturgeon can grow up to 7 feet in length and can weigh up to 300 pounds. Female sturgeon can live up to 80 years, while males live an average of 55 years.

Taken together, the Detroit River and St. Clair River reef-building projects represent the largest effort to date to restore a primitive, wild fish within a major urban area in the Great Lakes region.

The project’s core science team includes members from the University of Michigan (Water Center, Michigan Sea Grant), the U.S. Geological Survey’s Great Lakes Science Center, the U.S. Fish and Wildlife Service, and the Michigan Department of Natural Resources. The Michigan Wildlife Conservancy and the St. Clair-Detroit River Sturgeon for Tomorrow chapter are also collaborators.
