New understanding of Indonesian Throughflow could aid climate change forecasts

Honolulu, June 23, 2014
IPRCís James Potemra is co-author of a study led by Janet Sprintall of Scripps Institution of Oceanography at UC San Diego. The scientists have found that the flow of water in the Indonesian Throughflow Ė the network of straits that pass Indonesia's islands Ė has changed since the late 2000s under the influence of dominant La NiŮa conditions. This could in turn affect climate in both ocean basins in new ways. The study was published in the June 22 online issue of Nature Geoscience. Read more.

IPRC Director briefs Hawaii Commission on Water Resource Management

Honolulu, June 10, 2014
The Hawaii Commission on Water Resource Management (CWRM) invited IPRC Director Kevin Hamilton to present IPRC's continuing work on climate change projections for Hawai`i. A part of the Hawaii Department of Land and Natural Resources (DLNR), the commission’s mission is to protect the fresh water resources of Hawaii through wise and responsible management.  Administering the State Water Code created in 1987 by the Hawaii State Legislature, the commission is concerned that climate change will impact rainfall and evapotranspiration, and affect Hawaii's fresh water resources. Hamilton presented the ultra-high resolution climate projections for Hawaii produced by IPRC scientists and discussed ways in which effects of natural variability might be included in climate-change forecasts. DLNR Deputy Director Bill Tam hosted the meeting, which was attended by CWRM scientific and regulatory staff. Click here for photo.

Antarctic ice-sheet less stable than previously assumed

Honolulu, May 28, 2014
The first evidence for massive and abrupt iceberg calving in Antarctica, dating back 19,000 to 9,000 years ago, has now been documented by an international team of geologists and climate scientists, including IPRCís Axel Timmermann, Megumi Chikamoto, and Tobias Friedrich. The study, "Millenial-scale variability in Antarctic ice-sheet discharge during the last deglaciation,Ē in the May 28m 2014 issue of Nature bears witness to an unstable Antarctic ice sheet that can abruptly reorganize Southern Hemisphere climate and cause rapid global sea level rise.

Kauai dedicates memorial to 2011 Japan tsunami

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." IPRCís Nikolai Maximenko estimated the buoyís 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.

The tropical Pacific is primed for El Nino

Honolulu, April 11, 2014
“I would say there is an 80 percent chance that a big El Nino will develop by the end of the year. Just how powerful the phenomenon will be is the subject of intense debate within scientific circles,” IPRC’s Axel Timmermann was quoted as saying on the front page of the Star-Advertiser with regard to the recent predictions from NOAA about the possibility of an El Nino building up this summer through winter. In Timmermann's s opinion the El Nino will rival the one in 1997/98, the largest on record. Read more in Star-Advertiser.

Nikolai Maximenko talks on KITV4 about tracking debris from the 2011 Japan tsunami

Honolulu, March 11, 2014
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 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 plastic ones will break apart with time into smaller and smaller pieces recirculating in the ocean and becoming ingested by birds and marine animals. See interview.

Debris from tsunami continues to wash up in Hawaii

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 IPRCís 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.

What is El NiŮo Taimasa?

Honolulu, February 20, 2014
During very strong El NiŮo events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa. The Samoans call the wet stench of coral die-offs arising from the low sea levels taimasa (pronounced [kaií maísa]). The international study to uncover the reasons for this phenomenon and its climate effects, was spearheaded by IPRC's Matthew Widlansky and published in the Journal of Climate. Widlansky will speak at Ocean Sciences 2014 on the topic. Read more in Red Orbit; and Meteogiuliacci; and ScienceDaily.

IPRC Ocean Drift Model supports castaway fisherman's journey

Honolulu, February 13, 2014
The IPRC Ocean Drift Model developed by Nikolai Maximenko and Jan Hafner and used to track tsunami debris from Japan supports the improbable account of Jose Salvador Alvarenga, a Salvadoran fisherman, who says he survived more than a year adrift at sea before his boat washed ashore in the Marshall Islands. The 16 paths simulated in the model follow a remarkably narrow path over this long period of time toward and beyond Ebon Atoll, not more than about 120 miles apart. Click here or image for animation.

Wood objects sent adrift after the 2011 Japan tsunami have surprised researchers

Honolulu, January 5, 2014
University of Hawaii researchers Nikolai Maximenko and Jan Hafner, who are 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.
