Fukushima’s Radioactive Ocean Water Arrives At West Coast

Radiation from Japan’s leaking Fukushima nuclear power plant has reached waters offshore Canada, researchers said today at the annual American Geophysical Union’s Ocean Sciences Meeting in Honolulu.

Two radioactive cesium isotopes, cesium-134 and cesium-137, have been detected offshore of Vancouver, British Columbia, researchers said at a news conference. The detected concentrations are much lower than the Canadian safety limit for cesium levels in drinking water, said John Smith, a research scientist at Canada’s Bedford Institute of Oceanography in Dartmouth, Nova Scotia.

Tests conducted at U.S. beaches indicate that Fukushima radioactivity has not yet reached Washington, California or Hawaii, said Ken Buesseler, a senior scientist at the Woods Hole Oceanographic Institute in Woods Hole, Mass.

Wildlife

A Sanctuary for Manta Rays

Last month, Indonesia established the world’s largest sanctuary for manta rays — those enormous, finned fortresses that can reach nearly 30 feet across. For the first time, manta ray hunting and export is banned within the entire 2.3 million square miles of Indonesia’s exclusive economic zone.

The sanctuary is a victory for conservationists and the manta rays, as Indonesia was home to some of the largest ray fisheries in the world.

But the decree may not have been motivated solely by the plight of the rays, whose populations are dwindling in the archipelago. A study published last May in PLoS ONE calculated the measure of a manta and concluded the immense rays are worth much more alive than dead. For starters, the study reports that Indonesia earns an estimated $15 million in manta ray tourist revenues annually — compared to the ray fisheries, worth about $500,000.

Indonesian Forest Fires

Forest fires in Riau, Indonesia affect 20,000, while the haze drops visibility to 50 meters. At least 20,000 people in Riau province of Indonesia have suffered respiratory problems due to thick smog from the recent forest fires. The thick smog has also caused delay of flights in the Sultan Syarif Kasim airport.

Riaus disaster mitigation office has declared a state of emergency in the districts of Pelalawan, Bengkalis, Dumai city, and Meranti islands.

Roundup of Global Volcanic Activity:

Marsili Seamount (Tyrrhenian Sea, Italy): A recently published study shows that submarine explosive eruptions have occurred at the underwater volcano in historical times. Therefore, the volcano should be included as one of Italy’s still active volcanoes.

Kilauea (Hawai’i): (24 Feb) The Kahauale`a 2 lava flow reached 7.8 km (4.8 mi) northeast of Pu`u `O`o by mid-January before stalling. Recent surface flows have been active as small scattered breakouts behind the flow front.
