Scientists Find New Source of Radioactivity from Fukushima Disaster

Scientists Find New Source of Radioactivity from Fukushima Disaster

Scientists have found a previously unsuspected place where radioactive material from the Fukushima Dai-ichi nuclear power plant disaster has accumulated’”in sands and brackish groundwater beneath beaches up to 60 miles away. The sands took up and retained radioactive cesium originating from the disaster in 2011 and have been slowly releasing it back to the ocean.

Dispersants Improved Air Quality for Responders at Deepwater Horizon

Dispersants Improved Air Quality for Responders at Deepwater Horizon

A study published Aug. 28, 2017, in the Proceedings of the National Academy of Sciences adds a new dimension to the controversial decision to inject large amounts of chemical dispersants immediately above the crippled oil well at the seafloor during the Deepwater Horizon disaster in 2010. The dispersants may have significantly reduced the amount of harmful gases in the air at the sea surface’”diminishing health risks for emergency responders and allowing them to keep working to stop the uncontrolled spill and clean up the spilled oil sooner.

Fukushima Site Still Leaking After Five Years, Research Shows

Fukushima Site Still Leaking After Five Years, Research Shows

Five years after the Fukushima accident, scientific data about the levels of radioactivity in the ocean off our shores are available publicly thanks to ongoing efforts of independent researchers, including WHOI radiochemist Ken Buesseler, who has led the effort to create and maintain an ocean monitoring network along the U.S. West Coast.

Study Reveals Climate Change Impacts on Buzzards Bay

Utilizing 22 years of data collected by a network of citizen scientists, researchers from the Woods Hole Oceanographic Institution (WHOI) and their colleagues at the Buzzards Bay National Estuary Program, the Buzzards Bay Coalition, and the Marine Biological Laboratory found that average summertime temperatures in embayments throughout Buzzards Bay warmed by almost 2 degrees Celsius—roughly 4 degrees Fahrenheit.

Higher Levels of Fukushima Cesium Detected Offshore

Scientists monitoring the spread of radiation in the ocean from the Fukushima nuclear accident report finding an increased number of contaminated sites off the US West Coast, along with the highest detection level to date, from a sample collected about 1,600 miles west of San Francisco.  The level of cesium in the sample is 50 percent higher than other samples collected, but is still more than 500 times lower than US government safety limits for drinking water and well below limits of concern for direct exposure while swimming, boating, or other recreational activities.

Ken Buesseler, a marine radiochemist with the Woods Hole Oceanographic Institution (WHOI) and director of the WHOI Center for Marine and Environmental Radioactivity, was among the first to begin monitoring radiation in the Pacific, organizing a research expedition to the area just three months after the start of the ongoing accident. Through a citizen science sampling effort, Our Radioactive Ocean, as well as research funded by the National Science Foundation, Buesseler and his colleagues are using sophisticated sensors to measure minute levels of ocean-borne radioactivity from Fukushima. In 2015, they have added more than 50 new sample locations in the Pacific to the more than 200 previously collected and posted on the Our Radioactive Ocean web site.

Examining the Fate of Fukushima Contaminants

An international research team reports results of a three-year study of sediment samples collected offshore from the Fukushima Daiichi Nuclear Power Plant in a new paper published August 18, 2015, in the American Chemical Society’s journal, Environmental Science and Technology. The research aids in understanding what happens to Fukushima contaminants after they are buried on the seafloor off coastal Japan.

Trace Amounts of Fukushima Radioactivity Detected Along Shoreline of British Columbia

Scientists at the Woods Hole Oceanographic Institution (WHOI) have for the first time detected the presence of small amounts of radioactivity from the 2011 Fukushima Dai-ichi Nuclear Power Plant accident in a seawater sample from the shoreline of North America. The sample, which was collected on February 19 in Ucluelet, British Columbia, with the assistance of the Ucluelet Aquarium, contained trace amounts of cesium (Cs) -134 and -137, well below internationally established levels of concern to humans and marine life.

New Museum Program Focuses on Impacts of Fukushima on the Ocean

Four years after the Fukushima Dai-ichi nuclear power plant accident, Japan is still recovering and rebuilding from the disaster. In March 2011 one of the largest earthquakes ever recorded shook Japan, creating a devastating tsunami and damaging the Fukushima Dai-ichi nuclear power plant. The accident resulted in the largest unintentional release of radioactivity into the ocean in history.

On the fourth anniversary of the disaster, Woods Hole Oceanographic Institution (WHOI) and the Long Beach, CA-based Aquarium of the Pacific will debut a new program about ocean radioactivity motivated by the Fukushima nuclear accident. The program will be projected daily in the Aquarium’s Ocean Science Center on the National Oceanic and Atmospheric Administration’s (NOAA) Science on a Sphere® and will be made available to more than 100 institutions around the world through NOAA’s SOS Network with a capacity to reach over 50 million combined visitors.

Fukushima Radioactivity Detected Off West Coast

Monitoring efforts along the Pacific Coast of the U.S. and Canada have detected the presence of small amounts of radioactivity from the 2011 Fukushima Dai-ichi Nuclear Power Plant accident 100 miles (150 km) due west of Eureka, California. Scientists at the Woods Hole Oceanographic Institution (WHOI) found the trace amounts of telltale radioactive compounds as part of their ongoing monitoring of natural and human sources of radioactivity in the ocean.

Study Provides Some Answers to Fate of Deepwater Horizon Oil

Nearly five years after the Deepwater Horizon explosion spilled roughly 200 million gallons of oil into the Gulf of Mexico, scientists are still working to answer the question: Where did all the oil go?

A paper published today in the Proceedings of the National Academy of Sciences provides a piece of the puzzle with an analysis of the oil that ended up on the seafloor, establishing its footprint, rough quantity and likely deposition mode, and pegging its source to that deep ocean plume of oil.

WHOI-Led Study Sharpens Picture of How Much Oil and Gas Flowed in Deepwater Horizon Spill

In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well spewed oil at a rate of about 57,000 barrels a day, totaling nearly 5 million barrels of oil released from the well between April 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas.

WHOI Scientists Analyze, Explain the Chemical Makeup of Gulf Plume

Taking another major step in sleuthing the 2010 Deepwater Horizon oil spill, a research team led by the Woods Hole Oceanographic Institution (WHOI) has determined what chemicals were contained in a deep, hydrocarbon-containing plume at least 22 miles long that WHOI scientists mapped and sampled last summer in the Gulf of Mexico, a residue of the Deepwater Horizon oil spill.
