Alaska coast plays host to huge glob of floating goo
By Don Hunter ? McClatchy Newspapers ? July 15, 2009


ANCHORAGE, Alaska ? Something big and strange is floating through the Chukchi Sea off the Alaska coast.

Hunters from Wainwright, Alaska, first started noticing the stuff sometime probably early last week. It?s thick and dark and ?gooey? and is drifting for miles in the cold Arctic waters, according to Gordon Brower with the North Slope Borough?s Planning and Community Services Department.

Brower and other borough officials, joined by the U.S. Coast Guard, flew out to Wainwright, on Alaska?s north coast, to investigate. The agencies found ?globs? of the stuff floating miles offshore Friday and collected samples for testing.

Later, Brower said, the North Slope team in a borough helicopter spotted a long strand of the stuff and followed it for about 15 miles, shooting video from the air.

The next day the floating substance arrived offshore from Barrow, about 90 miles east of Wainwright, and borough officials went out in boats, collected more samples and sent them off for testing too.

Nobody knows for sure what the gunk is, but Petty Officer 1st Class Terry Hasenauer says the Coast Guard is sure what it is not.

?It?s certainly biological,? Hasenauer said. ?It?s definitely not an oil product of any kind. It has no characteristics of an oil, or a hazardous substance, for that matter.

?It?s definitely, by the smell and the makeup of it, it?s some sort of naturally occurring organic or otherwise marine organism.?

Something else: No one in Barrow or Wainwright can remember seeing anything like this before, Brower said.

?That?s one of the reasons we went out, because in recent history I don?t think we?ve seen anything like this,? he said. ?Maybe inside lakes or in stagnant water or something, but not (in the ocean) that we could recall ...

?If it was something we?d seen before, we?d be able to say something about it. But we haven?t ... which prompted concerns from the local hunters and whaling captains.?


The stuff is ?gooey? and looks dark against the bright white ice floating in the Arctic Ocean, Brower said.

?It?s pitch black when it hits ice and it kind of discolors the ice and hangs off of it,? Brower said. He saw some jellyfish tangled up in the stuff, and someone turned in what was left of a dead goose ? just bones and feathers ? to the borough?s wildlife department.

?It kind of has an odor; I can?t describe it,? he said.

Hasenauer said he hasn?t heard any reports of waterfowl or marine animals turning up.

Brower said it wouldn?t necessarily surprise him if the substance turns out to be some sort of naturally occurring phenomenon, but the borough is waiting until it gets the analysis back from the samples before officials say anything more than they?re not sure what it is.

?From the air it looks brownish with some sheen, but when you get close and put it up on the ice and in the bucket, it?s kind of blackish stuff ... (and) has hairy strands on it.?

Hasenauer said the Coast Guard?s samples are being analyzed in Anchorage. Results may be back sometime next week, he said.

The two Coast Guard experts sent up to overfly the area with the borough said they saw nothing that resembled an oil slick, Hasenauer said.

?We brought back one sample of what they believe to be an algae,? he said, and a big algae bloom is one possibility.

?It?s textbook for us to consider algae because of all the false reports of oil spills we?ve had in the past. It?s one of the things that typically comes up? when a report turns out not to be an oil spill after all.

But, he said, ?there?s all types of natural phenomena that it could be.?

Meanwhile, the brownish-blackish gunk is drifting along the coast to the northeast, Brower said.

?This stuff is moving with the current,? he said. ?It?s now on beyond Barrow and probably going north at this point. And people are still encountering it out here off Barrow.?

For the most part, the mystery substance seems to have stayed away from shore.

?We did get some residents saying it was being pushed against the shoreline by ice in some areas,? Brower said, ?but then we get another east wind and it gets pushed back out there.?

Re: Strange biological mass off of Alaska coast

We've had a long unseasonal stretch of warm weather - including the northern areas. Between that fact and less arctic ice to reflect solar heat, it's reasonable to suspect the ocean cooked up a new brew in it's warmer waters.

“It kind of has an odor; I can’t describe it,” he said.
Sure you can, just try. :D

Thanks for those pics, AD. That's strange looking stuff... we will impatiently await the test results.
 
Re: Strange biological mass off of Alaska coast

It looks like a filamentous floating algae (note the strands on the side of the bucket). I see it growing in large saltwater aquariums when the nutrient levels are elevated. If it's the same kind of thing, it starts out growing on the bottom and, as it releases oxygen as part of photosynthesis, bubbles get trapped in the mass and it floats. Once it begins floating, it gets more light and spreads like crazy. The stuff I've seen does have a strange odor.
 
Re: Strange biological mass off of Alaska coast

Looks like wet hair with mold.... ugh! It does not look good... looks like the consequence of using too much shampoo with chemicals stuff on it... maybe I'm just in bad mood, it can have some antivirals substance we need just now on it... :magnify: waiting for the researchers to discover it! :)

Article about filamentous algae in ponds:
http://ohioline.osu.edu/a-fact/pdf/A_3_09.pdf

It says it's encouraged by AG runoffs, etc., well there's no agriculture there, only tiny community waste treatment plants. The article also blames canadian geese feces runoff - well there LOTS of migratory birds on the north slope of Alaska in the summer. They're loosing their habitat in the SE and interior part of the state, due to melting permafrost draining their ponds, so I was assuming they'd fly further north to where the ponds/small lakes won't drain. But that theory is a long shot. I'll bet on warming ocean water.

Re: Strange biological mass off of Alaska coast

With my tinfoil hat on, I'll guess that it's from a big boatload of those (partially banned) gm french fries that someone illegally dumped off-shore. That stuff is even growing hair. It appears to be flesh-eating since only bones and feathers were left from the dead goose. LOL. I'm just joking!!

Brower's comments seem inconsistant. Either they've seen something like it before or they haven't.

Well, we all love a mystery.

This Abstract seems to describe a similar phenomenon.

Are Drifting Algal Mats Conquering the Bottom of the Archipelago Sea, SW Finland?

Petri Vahteri1, Anita M?kinen2, Sonja Salovius3, and Ilppo Vuorinen4

Abstract
The occurrences of drifting algal masses were mapped in the Archipelago Sea, Northern Baltic Sea, during the summers of 1996?1997 using an UW-video and SCUBA-diving. The study covers depths from the shore down to 50 meters. The algal masses were described and classified according to the thickness of the mass and possible occurrence of anoxia (smell of hydrogen sulfide, black colored sediment), i.e. indicators of the masses potential different ecological impacts. Three different types of drifting algal masses were distinguished: cover, mat, and mattress. The succession of the masses was studied during one growing season. First, the algae aggregate on the sea floor as a thin cover. Later they start to drift downwards along the sloping bottom, developing into partly anaerobic mats and further into totally anaerobic mattresses. The phenomenon was most severe in the outer archipelago of the SE corner of the study area. Factors contributing to the growth of ephemeral algae, which result in drifting algal mats, include high nutrient loading, good water transparency, and appropriate bottom substrate. During the study we became convinced that the UW-video system is a practical tool for studying underwater loose-lying algal masses.
 
Re: Strange biological mass off of Alaska coast

good water transparency

If they mean clean water - the Alaska area has that.

If they mean transparent enough to allow significant sunlight penetration - thanks to melting arctic ice pack, they now have that, but never did before (or at least for several thousand years.)

Black goop afloat off Arctic coast identified as algaeALGAE: Still, experts don't know why there's so much of it.

A sample of the giant black mystery blob that Wainwright hunters discovered this month floating in the Chukchi Sea has been identified.

It looks to be a stringy batch of algae. Not bunker oil seeping from an aging, sunken ship. Not a sea monster.

"We got the results back from the lab today," said Ed Meggert of the Department of Environmental Conservation in Fairbanks. "It was marine algae."

Miles of the thick, dark gunk had been spotted floating between Barrow and Wainwright, prompting North Slope Borough officials and the Coast Guard to investigate last week. A sample was sent to a DEC lab in Anchorage, where workers looked at it under a microscope and declared it some kind of simple plant -- an algae, Meggert said.

The goo fast became an Alaska mystery. And the new findings still leave questions unanswered: Why is there so much of it in a region where people say they've never seen anything quite like it?

Local hunters and whalers didn't know what to make of it. The Coast Guard labeled the substance biological, but knew little else. The stuff had hairy strands in it and was tangled with jellyfish, said a borough official.

Terry Whitledge is director of the Institute of Marine Science at the University of Alaska Fairbanks. He hasn't had a chance to look at the DEC's sample yet, but a friend with the National Oceanic and Atmospheric Administration e-mailed him a picture of the gunk.

"Filamentous algae," he concluded.

Filamentous?

"It means it's just stringy."

Whitledge said he doesn't know why an unprecedented bloom of algae appeared off the Arctic coast.

"You'll find these kind of algae grow in areas that are shallow enough that light can get to the bottom ... If you had a rocky area along the coast, you could have this type of algae."

It could have been discharged from a river, he said, flushed out by runoff from spring breakup and melting ice. But that's just speculation, he warned.

The North Slope Borough took samples of the stuff too, for a separate round of testing, said Coast Guard Petty Officer 1st Class Terry Hasenauer.

The results of the state's analysis came in at 10:30 a.m. Thursday. It was the last day on the job for Meggert, the retiring on-scene coordinator.

"Had it been petroleum, then we really would have had our work cut out for us," he said.

That was the initial fear -- that an oil spill had appeared in the Chukchi Sea, or maybe the blob was oil bubbling up from a sunken vessel or underwater seam.

The goo didn't fit any pattern that made it easy to identify from afar, Meggert said. "First of all, it was at the end of the Earth. Pretty hard to get to.

"While we've seen some algae bloom from time to time, we really haven't seen something quite like this."

The color, in particular, didn't make sense, he said. You might expect to see green or reddish algae but not this black, viscous gunk. Whitledge, with the university, said one possible explanation is that the algae has partially decomposed into a darker hue.

He looks forward to the university examining the sample too, to identify exactly what kind of algae it is.

It's worth noting that Alaska Natives in the region reportedly hadn't seen anything like it before, he said.

But asked if the blob's surprise appearance could be connected to global warming, Whitledge hesitated to draw a link.

"The water's actually very cold this year compared to other years," he said.

Changed visibility and water by deminished salinity, because of the ice melting.
