Japan tsunami debris could reach B.C. in days: oceanographer

A photo released by the International Pacific Research Center at the University of Hawaii October 24, 2011 shows a Japanese fishing boat found by a Russian ship in the northwest Pacific. A fishing boat from Fukushima and other debris have been found in the Pacific at a location suggesting that flotsam from Japan's tsunami is drifting east faster than expected, researchers say

VICTORIA — The largest items swept out to sea following the Japanese tsunami in March could arrive on the B.C. coastline within days, oceanographer Curt Ebbesmeyer predicted on Wednesday.

The main part of the 20-million-tonne debris field, equivalent in size to the state of California, isn’t expected until about 2014
, but houses, fishboats and even small freighters could already be close to Canadian shores, Mr. Ebbesmeyer said.

“We just finished running a simulation with a drifter, a buoy that got lost in the area of the tsunami, and we find that the first of the debris would be here now,” Mr. Ebbesmeyer said.

Beachcombers along the west coast of B.C. should be on the lookout and report any unusual finds, he said.

Mr. Ebbesmeyer is a Seattle-based oceanographer, educated at the University of Washington, who tracks flotsam using computer models. He has consulted for multinational firms, working on projects such as the BP oil spill in the Gulf of Mexico.

The March 11 earthquake and tsunami in Japan prompted Mr. Ebbesmeyer and fellow oceanographer Jim Ingraham to run computer simulations on the path of debris carried out to sea by the tsunami.

Debris moves faster if it is exposed to the wind, Mr. Ebbesmeyer said.

A mostly submerged buoy measuring ocean currents can move 11 kilometres in a day, but a small fibreglass boat can travel three times faster, he said.

“People who base their results on satellite-tracking buoys get a slower speed than those of us who track Nike shoes and hockey gloves and airplane wings,” Mr. Ebbesmeyer said.

Researchers Nikolai Maximenko and Jan Hafner at the International Pacific Research Center in Hawaii are monitoring the debris field through computer models and ship reports.

Mr. Hafner said Wednesday that windblown flotsam isn’t part of his research. He said ocean currents will deliver a significant amount of plastics to this area in 2013 or 2014. The majority will remain in a North Pacific “garbage patch,” where swirling currents surround a vast amount of seaborne junk.

The crew of a cargo ship near Midway Island spotted an 18-foot vessel in the debris field, Mr. Hafner said.

The Japanese have immense respect for belongings such as fishing boats, said Mr. Ebbesmeyer, predicting an influx of Japanese tourists coming to B.C. to see the washed-up debris.

“When people find something on the beach, they are literally putting their hands on something that a family wants to know about,” he said.

A Japanese fishboat that washed ashore in Prince Rupert, B.C., several years ago has become a shrine to fishermen lost at sea, he said.

Tofino, B.C., beachcomber Barry Campbell can relate. A few years ago, he found a sealed bottle on the beach containing a note written by students at a Japanese school.

He wrote to the school “and got a huge stack of letters from each individual class, but most of them were in Japanese.”

Mr. Ebbesmeyer is asking anyone seeing floating debris of an unusual nature to take a photograph and send it to him through his website at flotsametrics.com.

A Transport Canada spokeswoman said contingency plans are in the works to deal with debris that might pose navigational hazards in Canadian waters.

Nice post Shy, I am up in the Mountains this weekend, but will be back on the coast Monday, perhaps I will take the boat out and start looking.

Scientists warn Japan tsunami debris endangering Hawaii

A fire is seen in an area overcome by the tsunami in this photo taken from a Mainichi helicopter in Natori, Miyagi Prefecture, on March 11, 2011.

(Mainichi)LOS ANGELES (Kyodo) -- Hawaii's environment could be in danger as debris from Japan's earthquake and tsunami in March, including lumber and home appliances adrift in the Pacific, has been approaching, researchers said at a meeting in Honolulu on Monday.

"The larger the piece, the more dangerous the piece," said Nikolai Maximenko of the International Pacific Research Center at the meeting on mitigating the impact of the debris on coastlines.

Large debris could damage reefs and shore-side facilities, while small debris could pollute beaches and injure endangered species such as the Hawaiian monk seal, said speakers from the National Oceanic and Atmospheric Administration and marine cleanup groups.

Maximenko showed a hypothetical plan to set up floating barriers near the Midway Islands, between Japan and Hawaii, and the northwestern coast of the U.S. mainland and actively collect the debris on a path toward land."No plan is ideal. But if you don't have a plan, you cannot do anything," Maximenko said, warning that only immediate action could intercept the debris before it starts landing on Midway.

It would be the best place to intercept debris, said Maximenko, because projections show that after passing Midway, the debris will head toward the Papahanaumokuakea Marine National Monument, more than 350,000 square kilometers of protected reefs and waters listed as a UNESCO World Heritage site last year.

But other participants said immediate work will be difficult due to rough sailing conditions caused by winter storms as the debris is then expected to start landing on the main Hawaiian Islands next March.

Tsunami debris issues addressed by state
Hannah Heimbuch       

A Friday panel discussion in Anchorage covering potential tsunami debris from Japan put several concerns to rest — for the time being — and shed light on some sensitive issues. But some in the Northwest Alaska region aren't convinced.

Sen. Lisa Murkowski hosted the group, with representatives from various environmental, health and marine debris monitoring organizations.

A good deal of expertise graced the roundtable for the hour, and for the most part unanimously highlighted one thing — there is no current concern about radioactive materials traveling to Alaska waters as a result of the tsunami disaster in Japan last March.

Kristin Ryan from the Alaska Department of Environmental Conservation cited water and air testing in both Alaska and Japan, and said water tests just 30 miles off Japan's shores showed radiation levels as low as American safe drinking water standards.

"If the water is safe that close to Japan, you can be assured that the water 2,000 miles away in Alaska is most likely unaffected," Ryan said.

But it's still a concern for Point Hope Mayor Steve Oomittuk, whose community reaches into the Chukchi Sea and regularly collects foreign debris on its shores.

"So we were concerned about the earthquake and the radiation that went into the water," Oomittuk said, "because we do receive Japanese debris, and the animals that we hunt are (from the) ocean, and we were concerned about the contamination getting into the food chain."

Oomittuk said the village of Point Hope has faced a number of concerns over marine health this winter, including a still unexplained outbreak of disease infecting and killing ringed seals. He said between that and fears of radiation, some villagers have stepped back from usual hunting practices.

"We're ocean people. We hunt seals. And now not too many people are hunting seals because they're afraid to eat them," Oomittuk said.

He said he and his fellow Point Hope residents need some solid feedback from the scientific community about their concerns before people will be comfortable with the harvest again.

Leaders from other coastal cities expressed less concern over this issue, such as Kivalina Mayor Tom Hannifan. He said he hasn't heard anything from fellow residents expressing contamination concerns, or worries about debris arriving.
