The US Department of States Office of Foreign Missions (OFM) launched a new outreach initiative, Greening Diplomacy. To raise awareness and help stem the tide of pollution through coastal cleanups, the OFM invited the Hawaii Consular Corps (CC) to join the 30th anniversary of the International Coastal Cleanup (ICC) Day, held at the Campbell Wild Life Refuge. Consular Corp Members from Japan, Korea, Taiwan, and Switzerland participated. IPRC Marine Debris Project Members also joined the event that was led by ICC Coordinator Chris Woolaway. Among the debris collected were items that probably stem from the 2011 tsunami: a dock with a concrete shell over styrofoam, a refrigerator door and crates from Fisheries in Iwate Prefecture. Participants removed between 1,000 to 2,000 pounds of plastic debris and fishing lines from 150 feet of shoreline. Click for group photo; for selected items removed.

Joao Pedro Cardoso became the second IPRC marine debris team intern from Brazil. An undergraduate oceanography student from Rio de Janeiro State University, Joao is on a 12-month scholarship from the Brazilian government program called “Ciências sem Fronteiras” (Science Without Borders). Most of his internship he spent at Monterey Bay California State University. He chose to come to the IPRC for the 2-month-internship requirement to study with Nikolai Maximenko and Jan Hafner the problems of marine debris. As part of his internship, he did coastline marine debris surveys of several windward beaches on Oahu. With Maximenko, he developed a method for creating a marine debris photo database, which can be searched and analyzed using MATLAB. His visit was fruitful for all and we will miss Joao.

Yomiuri Shimbun, a leading daily newspaper in Japan, plans to feature an update on the driftage from the tragic 2011 tsunami. Thus, Norimasa Tahara, who has recently become the Chief of the newspaper’s Los Angeles Bureau and reporter Sam Hecht, who is also with the Los Angeles Bureau, visited the IPRC and talked with Nikolai Maximenko, Jan Hafner, and Joao Pedro Rodrigues (intern from Brazil) about the most recent IPRC research and findings on the tsunami debris in North America and about the ever-growing global problems with marine debris.
Miyako-city, Okinawa Prefecture, May 12, 2016
The Research Vessel Kaisyou of the Kesennuma Local Fisheries Laboratory in Miyagi_Prefecture was sucked out into the Pacific during the tragic 2011 tsunami in Japan. In May 2016, the boat was found about 4 miles offshore from Miyako-jima, Okinawa Prefecture. The IPRC Drift Model, developed by Nikolai Maximenko and Jan Hafner and used to chart the drift path of millions of tons of debris from the tsunami, simulated the likely route the Kaisyou drifted during its astonishing 5-year-2-month-long journey, floating eastward across the Pacific during 2011 and 2012 and then circulating back westward during 2013 to 2016.

A group of fifth-grade students at Hahaione Elementary School in Honolulu are studying marine debris. To learn more from scientists, the students visited the IPRC and met with Jan Hafner. Hafner showed them how ocean currents and winds push floating marine debris along pathways in the large ocean gyres and how the Great Pacific Garbage Patch forms. The students inspected with fascination the pieces of wood and the refrigerator door that washed into the ocean during the 2011 tsunami and then floated from Japan all the way to Hawaii. They were curious about the different types of plastic debris samples that Hafner showed them and were amazed at how larger pieces of plastic get ground down into microplastics over the years.

The tiny Daini Katsu Maru washed onto Oahu’s shores on April 22, 2015, more than 4 years after the devastating 2011 Japan tsunami sucked it into the ocean in Ogatsu-town. The 30-foot fishing boat’s likely journey was charted by IPRC’s Jan Hafner based on an analysis with the IPRC Ocean Drift Model. It probably wandered around in the Great Pacific Garbage Patch for some time according to IPRC’s Nikolai Maximenko, who was interviewed by Hawaii Department of Land and Natural Resources (DLNR) and by Hawaii News Now TV station. Loaded under fanfare on February 20 onto the Miyagi Maru, the Daini Katsu Maru is returning home, where it will be displayed at a cultural center being planned by the newly formed Daini Katsu Maru Preservation Society to commemorate the earthquake and tsunami.

Eight million tonnes of plastic estimated entering the ocean every year jeopardize fish and other marine life on which we depend. Much of it comes from landfills leaking one-third of the 78 million tons of plastic collected annually. On January 19-21, the IPRC hosted the Workshop on Mission Concepts for Marine Debris Sensing, which was sponsored by NASA Physical Oceanography and co-organized by Remote Sensing Solutions, Inc. The international group of oceanographers, remote sensing scientists, and marine debris experts came together to review existing and emerging technologies and to draft the mission objectives. Discussions included characterization of different types of debris, identification of gaps in our knowledge, and requirements for the future observing system. The meeting began work on a white paper that will be produced with contributions from a larger scientific community. (Click for photo)

The book 438 Days, just published by Simon & Schuster and authored by Jonathan Franklin, tells the story of the fisherman Jose Salvador Alvarenga's over 14-month-long drift from Mexico westward across the Pacific to Ebon Atoll in the Marshall Islands. To verify his unlikely story, Nikolai Maximenko and Jan Hafner had run the IPRC Drift model by placing tracers into the model 200 nautical miles southwest of the coastal fishing village Chiapas, Mexico, on December 20, 2012, around the time that Jose Salvador Alvarenga says he was blown off shore. The simulations, which they published in February 2014, confirmed the fisherman’s story, and they were then contacted by Franklin, who has acknowledged in his book their help “to understand the wild of the Pacific Ocean."

The team from Holomua Elementary School that interviewed Jan Hafner about microplastic for the Trash TreckSM 2015 FIRST LEGO League Robotic Competition, won at the District Challenge first place for both Robot Mission and Project Presentation. Their winning design is a solar-powered Nurdle Turtle, inspired in part by Hafner’s description of floating and sinking debris. About 5-ft. long & 4-ft. tall, the turtle scoops up sand that is then deposited into a compartment filled with water. The sand sinks while the microplastic floats to the top, where it is collected by a robotic arm and dropped into a second compartment where it stays until emptied. A trap door opens to release the sand.
We wish the team good luck on December 5, when they compete at the Hawaii State level at Neal Blaisdell Center.
Honolulu, October 7, 2015
Jan Hafner has been busy helping student-groups prepare for the 2015 FIRST® LEGO League, which has the theme "TRASH TREKSM Challenge". His pictures and simulations let students understand how ocean debris moves through the gyres and collects in "garbage patches." He shows them real pieces that have drifted to Hawaii from the 2011 tsunami as well as other plastic debris of various shapes and sizes, including nearly invisible micro plastics.This all makes the students aware of the huge ocean debris problem. In the photo you see a group of 5th grade Punahou students with Hafner (right) and Nikolai Maximenko. Together with Kin Wang, Hafner held a similar session via Face Time with students at Holomua Elementary School.

Kauai, May 16, 2014
A buoy from Onahama Bay, the port of Iwaki City in Tohoku, was washed away during the 2011 tsunami in Japan. It was picked up by the US Navy off Kauai shores in January 2013 and now forms at Port Allen the centerpiece of a memorial to the tragic tsunami. The dedication ceremony featured speakers and cultural activities from both Iwaki City and Kauai County, which coincidentally are "sister cities." IPRC’s Nikolai Maximenko estimated the buoy’s nearly two-year journey across the Pacific based on calculations with the IPRC tsunami debris model he developed together with Jan Hafner. The map of the calculated path is featured on the memorial's plaque, which lists IPRC as one of the sponsors. See plaque photo; watch video; watch HawaiiNewsNow; and read Star-Advertiser.

On the 3-year anniversary of the tragic tsunami in Japan, IPRC's Nikolai Maximenko was interviewed by Cam Tran of KITV4 about his work on tracking the tsunami driftage in his model and in observations. He described the different type of debris arriving in Hawaii during the three years: very boyant objects about 18 months after the tragedy, then refrigerator parts and little boats, and recently pieces sitting deep in the water such as large beams and poles. Many pieces, especially the plastic ones will break apart with time into smaller and smaller pieces that recirculate in the ocean and become ingested by birds and marine animals. See interview.
Honolulu, March 6, 2014
Upon reports of a huge beam washing up on the shore near Travaasa Hana Resort on the east end of Maui, Gary Kubota from the Star-Advertiser interviewed IPRC’s Nikolai Maximenko. Maximenko said he suspected the wooden beam to be from the tragic 2011 tsunami in Japan, as pictures showed that the beam had similar mortise and tenon features as other beams that have recently been reaching Hawaii shores, including wood from houses broken apart in the disaster. Wind and currents are the two major factors influencing the drift of the tsunami debris. Read more in Star-Advertiser Print Replica.
Honolulu, February 21, 2014
The amount of debris in the ocean is growing exponentially, becoming more and more hazardous and harmful to marine life and therefore to our ocean food source. The technology of measuring the movements of such debris is still in its infancy. The driftage generated by the tragic 2011 tsunami in Japan gave IPRC's Nikolai Maximenko and Jan Hafner a unique chance to learn about the effects of currents and winds on floating materials as they move across the North Pacific Ocean. The outcomes are presented at the Ocean Sciences 2014 meeting. See PowerPoint presentation. Read more in International Business Times, and in Ideas, Inventions, and Innovations; and Science Daily.

Honolulu, January 5, 2014
University of Hawaii researchers Nikolai Maximenko and Jan Hafner, monitoring the tsunami debris, say objects such as boats, buoys and lighter materials are being replaced with a steady stream of heavier wooden beams and planks. The IPRC website logs reported debris that comes ashore. Since Sept. 24 it has documented nearly two dozen poles, beams, planks and other wooden building materials washing up on diffieren Hawaii beaches. Maximenko is surprised that wood could stay afloat for such a long time, which raises the ecological question how floating trees could carry marine and vegetation to Hawaii.

Jono Blodgett, an aquatic-invasive-species supervisor with Hawaii’s Division of Aquatic Resources, says in the Japan Times that ocean trash arriving in Hawaii is not generally a concern for invasive species. Tsunami debris that has been sitting in Japan’s coastal waters for many years, however, has had time to grow local species. When these species are now transported across the Pacific on the debris, they pose a threat of becoming invasive to Hawaii. In conjunction with this news story, IPRC's Jan Hafner was interviewed about the IPRC tsunami debris model, which creates maps that project where various types of the tsunami debris travel over time. More in the Japan Times.

Using the model developed for the 2011 tsunami debris, IPRC’s Nikolai Maximenko and Jan Hafner are projecting paths for debris that might have been generated by super typhoon Haiyan in the Philippines. According to the model, any typhoon-generated marine debris is expected to move westward through the Philippine Archipelago into the South China Sea. Unclear is whether from there it would be carried to the coasts of Vietnam or would be diverted by currents and winds to different shores of the South China Sea. Read press release.
Honolulu, November 14, 2013
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. IPRC’s 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.
Honolulu, November 7, 2013
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 IPRC’s 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.

Honolulu, January 25, 2012
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.

Listen and read more.
December 15, 2011
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.
