Psst! I think cyanobacterium is an enormous jerk

Algae (L), Cyanobacterium (R).

You might have heard.

We've got this new guy strutting around the station telling us to "get it right."

Well, I've had just about enough of this guy. I'm sharing my thoughts about him in this vlog (video blog, for the uninitiated).

I hope you can help me get rid of him.

This guy gets all offended when you call him "algae"

If you go out in western Lake Erie right now, you'll see us.

We turn the water green. The wakes of the boats -- normally a frothy white -- we turn them a frothy green.

We've been at it for billions of years, and the more you feed us (thank you farmers and the people of metro Detroit), the more we multiply in your warm slow moving waters. But when experts and reporters talk about us, they call us "toxic algae."

Algae? Seriously? Just because we look like plant-scum growing in the water doesn't mean that's what we are.

We are the only kind of bacteria that can release the microsystin toxin into water supplies.

Scientists are starting to call us by the right name. My scientist-friends talked with Rebecca Williams about it today for the Environment Report, thank goodness.

And now I'm trying to work on the reporters and hosts at Michigan Radio.

Green goo growing in Lake Erie is not what you think it is

Western Lake Erie turns green from cyanobacteria blooms.
Mark Brush Michigan Radio

 

Lately, that green slime in the lake has been all over the news after it shut down Toledo’s water supply.

Journalists, city and government officials have been calling that green slime  “blue-green algae”, “toxic algae” or “toxic algal blooms.”

Well, turns out that’s not exactly right.

“That’s just maddening,” said James Bull, a professor of biology and environmental science. He works at Wayne County Community College and Macomb Community College.

He says it’s not accurate to call the green slime that shut down Toledo’s water system “a toxic algal bloom.” 

He wrote to Michigan Radio because we were some of the people using the wrong term.

“It’s wrong because even though these organisms superficially look like algae, I think we ought to understand that these really are a kind of bacteria,” Bull said.

He says scientists used to call this stuff “blue-green algae.” Now they call it “cyanobacteria”. He says calling cyanobacteria "algae" is like calling a dolphin a fish.

TOLEDO, Ohio – The findings of a toxin in the drinking water supply of 400,000 people in Ohio and southeastern Michigan a week ago is putting a big spotlight on how it got there.

Scientists and farmers agree that phosphorus from agriculture runoff is feeding the cyanobacteria blooms on Lake Erie linked to the microcystin toxin.

Political leaders are calling for more studies to find out why the blooms are increasing and how to control them. But a number of environmental groups say it's time for strict regulations on the agriculture industry.

TOLEDO, Ohio (AP) - Ohio's fourth-largest city has warned residents not to consume its water after tests revealed the presence of a toxin possibly related to cyanobacteria on Lake Erie. Toledo issued the warning early Saturday. It said tests at one treatment plant returned two sample readings for microsystin above the standard for consumption. The city warned against boiling because it will only increase the toxin's concentration.

Researchers predict smaller cyanobacteria problem in Lake Erie this year

Algae blooms are predicted to be smaller in Lake Erie in 2014. Last year's bloom was large due to a relatively wet spring followed by a wet July.
Mark Brush Michigan Radio

 

The forecast is in: the green goo will be back on Lake Erie this year, but it won’t be as bad as last year.

The big, ugly blooms of cyanobacteria (sometimes referred to as blue-green algae) happen when excess nutrients — mostly phosphorus — run off into the lake from farms and sewage treatment plants. Some of these kinds of cyanobacteria produce toxins can harm pets and make the water unsafe to drink.

Rick Stumpf is an oceanographer with the National Oceanic and Atmospheric Administration. He says they’re predicting this year’s bloom in Lake Erie will be significant, but not as bad as it has been in recent years. The blooms reached a record level in 2011.

Stateside for Tuesday, March 11, 2014

The Detroit automakers are moving into their fifth year of recovery after the disastrous bottoming-out of 2009 when General Motors and Chrysler filed for bankruptcy. Half a decade later, however, sales are brisk and auto loans are available. But is the future that bright? On today's show: Are there warning signs of another auto downturn? And, if so, what needs to happen to stop it?

Then, what will our rivers and roads look like once spring hits and the snow melts? We spoke with meteorologist Jim Maczko to find out.

Lake Erie is full of blooms of cyanobacteria (sometimes referred to as blue-green algae) and dead zones, and a new report is asking us to take action. What can be done to improve the health of this lake?

Also, how about adding smell to food advertising? 

First on the show, are Michigan veterans getting what they deserve in terms of benefits and support?

The Veterans' Administration says when it comes to per-capita spending on veterans, Michigan checks in at an average of just over $3,400 per vet. The national average is over $4,800. That places Michigan last in the nation.

What is the state doing about this and to make sure that veterans get all the benefits to which they're entitled?

The director of Michigan's Veterans Affairs Agency, Jeff Barnes, joined us today.

What can be done about cyanobacteria blooms and dead zones in Lake Erie?

Algae in Lake Erie.
Mark Brush Michigan Radio

If you lived in Michigan in the 1960s and '70s, you will remember: Lake Erie was on the "critical list." It was once declared dead.

But it got back on the road to health and recovery until the mid-1990s.

That's when the lake started showing signs of distress, with large cyanobacteria blooms (sometimes referred to as blue-green algae blooms) and dead zones showing up again.

Now comes a report from an international agency that keeps a close eye on the health of the Great Lakes, and it is a clarion call to action. Among the agencies contributing to the report is the Graham Sustainability Institute at the University of Michigan.

Don Scavia, director of the Graham Sustainability Institute, joined us today.

Listen to the full interview above.

Clarification: An earlier version of this story referred to "algae blooms" in Lake Erie. These are really bacterial blooms (cyanobacteria) that look like algae. The copy has been clarified above.

More action needed to clean up Lake Erie, says international agency

Algae blooms have once again become common in western Lake Erie.
Mark Brush Michigan Radio

Massive blooms of cyanbacteria (sometimes referred to as blue-green algae) and dead zones in Lake Erie: These used to be major environmental problems around the most urbanized Great Lake back in the '60s and '70s, but they are problems once again.

Now, an international agency that keeps an eye on the health of the Great Lakes is calling for more action.

The International Joint Commission, a U.S.-Canadian agency, wants sharp cutbacks on phosphorus runoff getting into Lake Erie.

'Lake Erie has 2% of the water in the Great Lakes, but 50% of the fish'

The 2011 algae bloom on Lake Erie. Significant blooms returned to Lake Erie around 2000-01. Researchers are looking into how these blooms affect fish.

The stat comes from Jeff Reutter, Director of Ohio State University's Stone Laboratory. He says the converse is true for Lake Superior. It holds 50% of the water, but just 2% of the fish.

It's a rough estimate, he says, but it gives you a good understanding of how each of the five Great Lakes have unique characteristics, which present unique challenges in managing these lakes.

As part of our series on how climate change is affecting the Great Lakes, Reutter spoke to us about how Lake Erie is especially vulnerable to temperature variations. It is the southernmost, and the shallowest of the five Great Lakes.

He also spoke about how, unlike the other four Great Lakes, Lake Erie is surrounded by agriculture and a more urbanized landscape.

You can listen to him speak about his "50 and 2 Rule" here:

Lake Erie has seen a resurgence in blooms of cyanobacteria (sometimes referred to as blue-green algae) over the last ten years. It was once a big problem in the 60s and 70s, and it has returned as a problem again.

Warmer waters fuel toxic cyanobacteria blooms in the Great Lakes

Algae scooped out of Maumee Bay in Lake Erie.
Mark Brush Michigan Radio

Big, ugly blooms of cyanobacteria (sometimes referred to as blue-green algae) are reappearing in the western basin (and sometimes the central basin) of Lake Erie.

The blooms happen when excess nutrients – mostly phosphorus – run off into the lake from farms and sewage treatment plants.

Some of these kinds of cyanobacteria produce toxins that are among the most powerful natural poisons on Earth.

Over the past decade, these cyanobacteria blooms have been common in Lake Erie. And scientists predict climate change could make the problem worse.

Electrofishing survey finds no silver, bighead carp in Lake Erie

Don't worry, fish, I'm not gonna eat you. Fish temporarily stunned via electrofishing.
Michigan Department of Natural Resources

Silver and bighead carp don't appear to be living and breeding in Lake Erie - yet.

Environmental DNA from the fish was found in the lake near the Maumee River last year.  Environmental DNA comes from things like fish mucus, excrement, or scales.

But no Asian carp were captured in a recent electrofishing survey, which temporarily stuns fish with an electrical current.

Todd Kalisch is with the Michigan Department of Natural Resources.

Asian carp could find a good home in Lake Erie

Rebecca Williams Michigan Radio

Asian carp have been making their way up the Mississippi and Illinois Rivers toward the Great Lakes for decades. Bighead and silver carp are the species people are the most concerned about.

There’s been a lot of focus on keeping carp out of Lake Michigan.

But a new study finds carp might do well in Lake Erie and some of the rivers that feed the lake.

Patrick Kocovsky is a research fishery biologist with the U.S. Geological Survey. He says it’s believed Asian carp need specific conditions to make babies.

“What’s currently believed is Asian carp require some kind of flood event in a tributary.”

He says the carp need just the right temperature... a river that’s flowing fast enough and a stretch of river long enough to reproduce.

Kocovsky and his team studied the major tributaries of Lake Erie. They found that the Maumee River is highly suitable for Asian carp to lay eggs.

The researchers found the Sandusky and Grand Rivers to be moderately suitable for carp.

Patrick Kocovsky says if carp can get into Lake Erie, the western side of the lake is likely to be the most hospitable.
