A different type of possible tsunami debris is starting to wash up on the islands' shorelines: beams from houses or other wooden constructions, such as a 20-foot wooden beam at Malaekahana Beach on Oahu. IPRCís outreach specialist, Gisela Speidel, said the piece could indicate a new wave of tsunami debris headed our way. Before, oyster buoys or boats arrived, objects that sit high in the water and are more wind-driven. Now it is the more current-driven debris. Click to Watch KITV4 report.

Three long poles, perhaps tsunami debris from Japan, have washed up on Oahu windward shores over the past several days. One was found on Kalama Beach, part of Kailua Beach, two others at Malaekahana Bay. According to IPRCís Senior Scientist Nikolai Maximenko, the arrival of such pieces floating low in the water is consistent with the our IPRC model, which suggests that low-windage tsunami-debris is now arriving.

"The currents in the Northwest Pacific collect debris in the Great Pacific Garbage Patch. Winds and storms push the debris out of the patch again, and then the trade winds bring it to Hawaii. Recently the trades have been very strong. This is why we have seen more than the usual amount of debris washing up on Hawaii shores, much of it seems to be from the 2011 Japan tsunami," says IPRC Senior Scientist Nikolai Maximenko.

Twenty months after the Japan tsunami, little is known about the debris still floating in the North Pacific from the disaster. Fragmentary reports have come and are continuing to come from research vessels, small boats, and from sightings on coastlines, where debris washes ashore without warning. In this situation, numerical models, carefully tuned to use the little data available, continue to provide the main framework for tsunami debris planning and mitigation. Read more.

The IPRC Marine Debris Project was notified of possible tsunami debris from Japan washing up on the lava shore below Na`alehu. The giant container like object is metal, yellow, about 12 feet tall and 20 feet wide and could possibly be a pontoon for a floating dock. It was discovered Oct. 3 on state property, within the wash of the waves. Hikers came across the possible tsunami debris along the shore makai of Na`alehu, on the uninhabited Ka`u Coast. Read more.

The 5 Gyres Institute and the Algalita Marine Research Institute conducted a sailing expedition that left Japan on June 10, 2012, and sailed through the area where, 15 months after the catastrophe, the IPRC model predicted flotsam from the Japanese tsunami would be concentrated. The debris that was found, for instance parts of a crushed fishing boat and piece of a traditional tatami mat, fits the model's low-windage profile, indicating that much of the debris hasnít made it across the ocean yet.

Japanese scientists and governmental representatives met with IPRCís Tsunami Project Team on February 9 to exchange the latest information about efforts in locating the now widely dispersed tsunami debris. The mission of the task force is to identify the locations of the drifting matter washed into the ocean during the March 11 tsunami by using cutting-edge data assimilation techniques together with the best available ocean, atmosphere, and climate models, and to confirm these locations with satellite imagery and with observational reports. The task force, working under the umbrella of Japanese governmental organizations, is looking into cooperating with other governments on this project, in particular, with the United States.

The March 11, 2011, earthquake northeast of Japan and the impact of subsequent tsunami wave on the Tohoku coastline produced millions of tons of debris. A large amount of the debris was released into the ocean. Under the influence of winds and currents, floating debris is dispersing over a large area and drifting eastward; it is predicted to reach Hawaii and the West Coast of the United States within the coming two years. In order to obtain some certainty about the model predictions, an expedition was made to survey the ocean northwest of Midway during December. Read more about the survey.

Carried by ocean currents and winds, tsunami debris is expected to drift across the North Pacific from Japan toward the Northwest Coast of North America. The speed with which it drifts depends on its shape and composition. If the item is light and sticks out of water, it will drift much faster across the Pacific. The drum that washed on the shores of the Olympic Peninsula is such a light object; the part that sticks out of the water acts like a sail, and the wind can push it much more quickly than heavier objects. Researchers on the West Coast are now in the same position that our team has been for a while: verifying that the debris that has been found is indeed tsunami debris.

Workshop on November 14, 2011
The March 11, 2011, tsunami in Japan swept tons of debris into the ocean. Visible during the first weeks as yellow mats of complex composition, the debris quickly drifted offshore, dispersed and became invisible to existing observing systems. Predictions of ocean models have been confirmed by recent direct observations, which showed the edge of the debris field at the end of September only 300 miles northwest from Midway. The workshop focused on the necessity and feasibility of mitigating the impact of the debris on coastlines by using available knowledge, technologies, and resources.
