As a result of increasing atmospheric carbon dioxide concentrations, the chemistry of the Southern Ocean is expected to change so fast over the next few decades that small, but important, creatures at the base of the food web may soon struggle to form their carbonate shells. For some organisms the onset of such critical conditions will be so abrupt, and the duration of events so long, that adaption may become impossible, according to new research by Claudine Hauri, at both the International Artic Research Center (IARC) at the University of Alaska, Fairbanks and the IPRC, in collaboration with Tobias Friedrich and Axel Timmermann of IPRC.

The El Niño Southern Oscillation (called ENSO) is one of the most prominent climate events on the globe. Every two to seven years, temperature shifts cause modifications in wind and rainfall patterns in the Pacific, triggering changes in the climate around the world. A new study by Malte Stuecker and Fei-Fei Jin from Department of Atmospheric Sciences in collaboration with Axel Timmermann from IPRC present a new methodology which explores how interaction of the El Niño phenomenon with the annual cycle of solar radiation in the western Pacific generates a suite of predictable wind and rainfall patterns associated with the Southeast Asian Monsoons. In contrast to the inter-annual timescales of El Niño, monsoon oscillations occur on nearly annual timescales. The methodology provides a new way to explore atmosphere variability, as well as a number of other climate phenomena. Read the press release for more details.

Gradual sea-level rise due to climate-induced melting of world-wide ice deposits is a well-known scenario at this stage, and many island nations in the tropical Pacific are already coping with the reality of an encroaching ocean. However, recent modeling research by IPRC scientists Matthew Widlansky and Axel Timmermann suggest that more frequent and extreme short-term sea level fluctuations may soon become an additional challenge. The new model incorporates the effects of a warming planet on the El Niño-La Niña phenomenon. The results show that intensified winds will double the frequency of the sea level fluctuations associated with these global weather patterns, particularly affecting the tropical southwestern Pacific. Read the press release for more details. Watch HawaiiNewsNow; and read Star-Advertiser, Climate Central, and Discovery News, and Hakai Magazine.

What happens to ocean mixing in the central equatorial Pacific during the developing phase of an El Niño ? This and other questions were at the forefront of IPRC Director Kelvin Richards' mind as he set out from Majuro in late July on the Research Vessel Falkor with a team of scientists from UH and Korea. The scientists collected data close to the equator and dateline on the flow structures that create turbulence and mixing. The team has returned to Honolulu onboard the vessel. Now we await the story that the analysis of these exciting measurements will tell about the causes of ocean mixing and its impact on the coupled ocean-atmosphere system.

IPRC’s Axel Timmermann has been elected an American Geophysical Union Fellow. "Being elected a Union Fellow is a tribute to those AGU members who have made exceptional contributions to Earth and space sciences as valued by their peers and vetted by section and focus group committees. This honor is bestowed on only 0.1% of the membership in any given year," according to the EOS announcement. Timmermann and his 2015 American Geophysical Union Class of Fellows will be recognized at an award ceremony, held during the 2015 Annual AGU Fall Meeting in San Francisco, California.
Honolulu, July 21, 2015
IPRC Director Kelvin Richards heads out to the central equatorial Pacific to lead a science team from the University of Hawai`i, Seoul National University, and the Korean Institute for Ocean Science and Technology. On board the R/V Falkor operated by the Schmidt Ocean Institute, the team will gather data on small-scale turbulence in the region. Though coupling between the tropical ocean and atmosphere is known to be very dependent on the mixing produced by ocean turbulence, little is known about the mechanisms producing the turbulence. The new data set, combined with data from Richard’s previous work in other tropical Pacific regions, will let scientists determine more clearly what controls the mixing by turbulence. Among other things, the work will help improve the representation of ocean turbulence in models used to understand and forecast El Niño Southern Oscillations events (ENSOs). The Schmidt Ocean Institute and NSF are funding the three-week expedition. Read more.

A recent NOAA report shows that the global mean carbon dioxide concentrations reached 400 parts per million in March - the highest level on record. IPRC’s Axel Timmermann, interviewed by Beth-Ann Kozlovich on Hawaii Public Radio, talked about the implications of this new record. The last time CO2 concentrations were this high was 4 - 5 million years ago, when the Greenland and West Antarctic ice sheets did not exist and sea level was at least 30 ft. higher than today. He spoke about the accelerating rate of CO2 emissions, the difficulty of communicating the science to climate-change deniers, and the enormous behavioral changes needed to avoid reaching the 2C global mean temperature threshold for dangerous climate change within 20 to 50 years.

Tropical Pacific climate variations and their global weather impacts may be predicted much further in advance than previously thought, according to research by IPRC's Yoshimitsu Chikamoto and Axel Timmermann and their international colleagues in the USA, Australia, and Japan. The source of this predictability lies in the tight interactions between the ocean and the atmosphere and among the Atlantic, the Pacific and the Indian Oceans. Such long-term tropical climate forecasts are useful to the public and policy makers.

The International Pacific Research Center once again welcomed 21 Japanese high school students and their 3 teachers. They were from Morioka Daisan High School. The purpose of their trip to Hawaii was to be exposed to spoken English in an academic environment with a science focus. Morioka, the capital of Iwate Prefecture, suffered much devastation in the March 2011 tsunami. The students thus listened attentively to the 90 minute powerpoint presentation by IPRC’s Jan Hafner about the IPRC tsunami and marine debris model and how the model was able to track the travels of the debris across the ocean to the North Pacific Coast, and some of it into the Great Garbage Patch and then onto the north-east facing shores of Hawaii.

“..we will have to teach the decision makers about making decisions under the shadow of uncertainty," says IPRC’s Axel Timmermann in the Hawaii Business Magazine article about impacts of climate change on beach erosion, coral bleaching, and rainfall in Hawaii. Weather prediction is imprecise, yet if it is likely to rain, we take umbrellas as a precaution. To act or not to act depends upon the severity of the risk...the damage. “If we knew there was a 10 percent probability that by the end of the century sea level was going to rise nine feet…, the damage would be enormous,” says Timmermann about Hawaii.

What is El Niño Taimasa?
During very strong El Niño 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 [kai’ ma’sa]). 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.

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