New tool from Canadian scientists predicts warmer Great Lakes water temperatures

Great Lakes climate science is often stuck in the past. Studies show that all five lakes have warmed up over the past century. But they rarely predict how much the water will warm in the next one. A new tool from Canada could help buck that trend, warning policymakers of new threats from foreign organisms and other waterborne consequence of global climate change.

Farm runoff woes: Can voluntary programs alone keep dirt out of the water?

The Great Lakes and the Chesapeake Bay both field noxious summer algae blooms fueled by dirt and nutrients from farm fields. The six northeastern states that drain into the Chesapeake Bay have a patchwork plan to curb it. It doesn’t work and never will, says a recent report by the Environmental Working Group, a non-profit lobbyist and research group. The report claims runoff prevention programs fail because they’re voluntary — farmers that don’t want to participate don’t have to.

Special report: The alewife question

Alewives are a Great Lakes invasive fish that baffle native fish reproduction but give imported Pacific salmon — the target of a profitable fishery — something to eat. What’s a Great Lakes fishery manager to do? Sept. 2, 2009
Alewives: Should Great Lakes managers kill ‘em or keep ‘em? Fishery managers have made little progress in restoring lake trout, the Great Lakes’ dominant predator until the species collapsed in the 1940s and 1950s.

Great Lakes fish in the balance; biologists have little control

Editors note: This is the final story in a three-part series about the challenges of managing non-native fish in the Great Lakes. Managing invasive alewives in the Great Lakes is like walking a tightrope. Too many stymie native lake trout reproduction. Too few cripple the profitable salmon fishery.

Alewives: The trouble they cause and the salmon that love them

Editors note: This is the second of three stories in a series about the challenges of managing non-native fish in the Great Lakes. Pacific salmon, the big money species in the multi-billion dollar Great Lakes fishery, need a feast of alewives to thrive. But alewives are an invasive species that harm lake trout, a native fish that biologists have been trying and failing to re-establish for decades. Alewives keep lake trout down in two ways, said Mark Ebener, fish assessment biologist with the Chippewa Ottawa Resources Authority.

Editor’s note: This is the first in a series of stories about the challenges of managing non-native fish in the Great Lakes. Fishery managers have made little progress in restoring lake trout, the Great Lakes’ dominant predator until the species collapsed in the 1940s and 1950s. Most of them agree that alewives, a non-native fish, are a big part of the problem. They invaded the lakes from the Atlantic Ocean after the Welland Canal opened in 1932.

Going up and diving down: Exploring the Great Lakes with blimps and subs

A marshmallow blimp and a yellow submarine are gearing up to explore the Great Lakes from above and below. The SkySentry Aerostat — an unmanned blimp designed for military use — wouldn’t be out of place advertising a used car clearance sale, Michael Scott writes in the Cleveland Plain Dealer. Instead, officials are testing the big white blimp’s ability to collect imagery of Lake Erie algae blooms that turn the lake’s shallow western waters green and suffocate fish. Check the Plain Dealer’s story for video and a slide show.
