A new federal ruling could

Critics of sonar say it’s so loud that it confuses whales and other marine animals, and can cause them to be injured or even die. That’s why environmental groups have been pushing for tighter regulations on the technology.
This week the National Oceanic and Atmospheric Administration, or NOAA, took a step in that direction. The agency acknowledged that current policies are not doing enough to protect marine mammals. And NOAA says it will identify critical marine habitats impacted by sonar.
Michael Jasny is a policy analyst with the environmental group the Natural Resources Defense Council. He hopes the policy will be a first step to banning sonar in those habitats.
“It’s not a prescription, it’s a plan. And it sets in motion potentially a very significant change. I mean, the proof will be in the pudding, of course.”
Jasny says his organization will work with NOAA and the Navy to negotiate sonar policy so that marine mammals are not hurt.

Wind energy is among the fastest growing sources of new electricity generation. Now,
scientists are looking at ways to make wind turbines safer for birds and bats. The
GLRC’s Dustin Dwyer has more:
A study published last year by the Government Accountability Office says wind farms
have had little impact so far on birds and bats, but the study says that could change as
more wind farms go up. The question is how to minimize the risk.
Alex Hoar is with the U.S. Fish and Wildlife Service:
“Not all turbines cause a problem. There are turbines around that had bird
problems. There are lots of turbines that don’t. And we’re trying to learn why.”
Hoar says scientists know a lot about migration patterns for both birds and bats. But they
haven’t tracked the animals’ behavior while they’re in the air. Scientists are now using
thermal imaging and radar to study flight patterns in detail, and Bowling Green State
University in Ohio recently won a one million dollar grant to study the impact of smaller
turbines on wildlife.
Thirty years ago this month (November 10th), the iron ore carrier the Edmund Fitzgerald sank in Lake Superior. 29 men died. The lake carrier was caught in one of the worst storms recorded on the Great Lakes.

Thirty years ago this month (November 10th), the iron ore carrier, the Edmund Fitzgerald, sank in
Lake Superior. 29 men died. The lake carrier was caught in one of the worst storms recorded on
the Great Lakes. In the years since the Edmund Fitzgerald went down, the Great Lakes Radio
Consortium’s Mike Simonson has talked with those connected with the ship:
Like the folk song relates, the November gales came early on Lake Superior in 1975. A storm
more fierce than even the most experienced lake carrier crews had ever seen hit the eastern side
of the lake. That night, Captain Dudley Paquette was shipmaster of the lake carrier Wilfred
Sykes…
“We were really out right in the middle of the lake. Just huge seas, 30-35 foot seas. I was
completely awash and I was on a super ship. I was registering 70, 75 knots steady with gusts to
100. Huge seas, I was completely awash. Water was flying over the top of my bridge.”
Like the carrier Wilfred Sykes, the Edmund Fitzgerald was a big ship, but early in the night the
captain saw ominous signs of trouble. The topside fence rails had snapped. The vents were torn
off. The radar was out. And the Edmund Fitzgerald’s Captain, Ernest McSorley had all the bilge
pumps on, trying to keep the ship from swamping.
Thom Holden is the curator of the Army Corps of Engineers Marine Museum. He says Captain
McSorley was in radio contact with Captain Jesse Cooper of the nearest ship, the Arthur
Anderson.
“The topside damage was an earlier report. After suffering this damage that Captain McSorley
did contact Cooper and ask him to shadow him down the lake. It was really several hours later
that what could be the last transmission from the Fitzgerald was received. Essentially Captain
Cooper or the mate asked McSorley how he was doing, how the vessel was riding. He said
‘We’re holding our own, going along like an old shoe.'”
In an interview from his retirement home in Florida, Arthur Anderson Captain Jesse Cooper said
the memory of that night still haunts him. He says Captain McSorley didn’t let on that his ship
and crew were in danger.
“I think he knew he was in trouble but he couldn’t spread the word because it would panic the
crew. (Simonson): How do you think he knew he was in trouble? (Cooper) What the hell would
you think if you had a hole in your bottom and were taking in more water than you could pump
out?”
At 7:10 that evening, the Fitzgerald disappeared from radar as it sailed into a snow squall only a
few miles from the safety of Whitefish Bay.
“My gut feeling was I knew she was gone when I couldn’t see her on the scope. Turning around,
I hated the thought of going back out in that sea.”
Radio communication from that night was recorded by the Coast Guard at Sault St. Marie
Michigan. The Coast Guard was asking captains to turn back into the storm and search for the
Fitzgerald. You’ll hear a distressed Captain Cooper answer the call.
“(Coast Guard:) Think there’s any possibility that you could turn around do any searching, over?’
(Cooper) ‘Oh God, I don’t know. That sea out there is tremendously large. If you want me to, I
can but I’m not going to be making any time. I’ll be lucky to do two or three miles per hour going
back out that way, over.’ (Coast Guard:) It looks like with the information we have that it is fairly
certain that the Fitzgerald went down. We’re talking now a matter of life and death and looking
for survivors that might be in life rafts or in the water. We can only ask the masters to do their
best without hazarding their vessels.'”
The U.S. Coast Guard rescue vessel Woodrush had left the Duluth port but it took 21 hours to
arrive on scene. Captain Jimmy Hobaugh says a life ring from the Fitzgerald popped up as they
arrived.
“Of course we searched for the three full days and it was rougher than you can imagine. No
matter how I turned the ship, we were taking green water over the top. If there had been someone
there, I’m positive that my crew was good enough that we would’ve got ’em.”
None of the men’s bodies were recovered.
Among the crew of 29 was Third Mate Michael Armagost of Iron River, Wisconsin. His widow
Janice says the families of the 29 men who went down with the Edmund Fitzgerald struggle with
their loss…
“Nobody realizes that there are survivors. I mean, my kids’ father is on that ship and my
husband’s on that ship. And people just think of it as a shipwreck that happened so long ago, and
it’s not.”
The families of the crew of the ship now say all they want is the final resting place of their loved
ones to remain undisturbed by divers. Only the bell of the wreck of the Edmund Fitzgerald was
recovered and placed in the Great Lakes Shipwreck Museum at Whitefish Point, Michigan ten
years ago.

The emerald ash borer has been destroying ash trees in Michigan, Ohio,
Illinois, Maryland, and Ontario – and the bug is spreading. Now,
agricultural officials in Michigan are developing an early warning
system. By detecting the insects early, they hope to slow or even
prevent its spread. The Great Lakes Radio Consortium’s Tracy Samilton
reports:
Forestry agents will be designating a number of so-called trap trees in
every township in Michigan. The ash trees will act as sentinels. A
strip of bark will be removed from the trees, which stresses them and
makes them attractive to insects. A sticky substance called tanglefoot
will then be applied to the trees to catch the borers. Kara Bouchay is
with the Michigan Department of Natural Resources.
“Part of the struggle with having a borer that you can’t see most of
time because it’s underneath the bark, is when it’s in a low level
population, it basically flies under the radar. So the trap tree is a
way to bring it to a single location to detect it.”
If borers are found on a tree, all ash trees within a half-mile will be
destroyed to contain its spread. Bouchay says if the early detection
system proves itself, it will likely be implemented in other states as
well.
For the Great Lakes Radio Consortium, I’m Tracy Samilton.
