IPRC's Nikolai Maximenko and NASA's Eric Lindstrom are editors of the current issue of Oceanography, which features papers that give an overview of developments in remote sensing over the last few decades and how these developments open up new avenues of scientific inquiry. The intent of this special issue is to articulate areas of scientific inquiry that fuel the development of next generation satellite missions and to find out the upcoming challenges in oceanography using satellites.

IPRC’s Axel Lauer, Kevin Hamilton, and Yuqing Wang with colleagues at UHM and U. Wisconsin have just published a study using a new modeling approach that successfully simulates the observed cloud fields in a key region for climate. The study finds a greater tendency for clouds to thin with global warming than in any of the current global coupled climate models. Expected warming may thus be greater than currently anticipated.

Susan Avery, Director of Woods Hole Oceanographic Institution, presented this year's IPRC Public Lecture in Climate Science. In "A Changing Word, A Changing Ocean" Dr. Avery described the importance of the oceans for sustaining human life and noted that much of what happens in the ocean is hidden from view below the surface. While explaining the serious challenges now facing the ocean from human impacts of various kinds, Dr. Avery emphasized the role of science in helping us cope with and mitigate these impacts.

Scientists have known that atmospheric convection in the form of hurricanes and tropical ocean thunderstorms occurs when sea surface temperature rises above a threshold. So how do rising ocean temperatures with global warming affect this threshold? If it does not rise, it could mean more frequent hurricanes. The study by IPRC's Nat Johnson and Shang-Ping Xie shows this threshold is rising with global warming at the same rate as tropical ocean temperatures. Their paper appears in the Advance Online Publications of Nature Geoscience. More in Our Amazing Planet, Planetsave, press release.

IPRC’s Tim Li is lead author of the article "Global Warming Shifts Pacific Tropical Cyclone Location" (in press) in Geophysical Research Letters, which predicts that with global warming tropical cyclone genesis will shift from the western towards the central Pacific. The modeling study suggests that more hurricanes will hit Hawaii in the future. NewScientist. Click image for larger view.

IPRC Postdoctoral Fellow Yu Kosaka has been awarded the Yamamoto-Shyono Medal by the Meteorological Society of Japan (MSJ) for her work on wave-like teleconnection patterns along the summertime Asian Jet. Each year the society selects two top papers written by young scientists for the award. Kosaka will receive the medal at the October fall meeting of the MSJ in Kyoto.

Over 22 years, undergraduates in the Sea Education Program collected plastic pieces at 6100 locations in the North Atlantic. The highest concentration of plastic they found was in the region predicted by the drifter-based model developed by IPRC’s Maximenko, pointing out this model's usefulness in guiding ocean clean-ups. More in Science, press release, Raising Islands, Hawaii Public Radio, TGDaily, and about the model.

In a story by the Canadian Globe and Mail, IPRC senior scientist Annamalai was asked to comment on the revelation by the U.S. National Oceanic and Atmospheric Administration that Earth is on course for the hottest year since record-keeping began in 1880, that is, 0.7 degrees above the 20th-century average.

Toward the end of the last ice age, a major reorganization took place in the current system of the North Pacific, which may have buffered the global impacts of the collapsed circulation in the Atlantic, according to a study published by Yusuke Okazaki (JAMSTEC), Axel Timmermann (IPRC) and their international team in the July 9 issue of Science: read more in Science Centric, Planetsave, and Athena. Watch National Science Foundation interview.

The possible spread of the oil spill from the Deepwater Horizon rig over the course of one year was studied in a series of computer simulations by IPRC’s Axel Timmermann and Oliver Elison Timm, and Fabian Schloesser, PHD student in oceanography at the University of Hawaii (read more). The animation based on these simulations is posted on YouTube. For more on Hawaii Public Radio, in Staradvertiser, DiscoveryNews, DailyFinance, The Consumerist, WIRED.CO.UK.

The History Channel program, “Who really discovered America?” features IPRC senior researcher Nikolai Maximenko. The movie explores several possible “discoveries” of the Americas before Christopher Columbus “staked his claim in 1492.” Maximenko’s work on ocean circulation provides information about ocean currents and whether they could have helped those early seafaring voyagers. The program is airing several times from June 22 - 28.

Ocean surface temperatures can be expected to increase mostly everywhere by the middle of the century, but the increase may vary by up to 1.5°C depending upon the region. These emerging ocean temperature patterns in the tropics and subtropics will lead to significant changes in rainfall patterns, according to work by IPRC’s Shang-Ping Xie and colleagues (more).

IPRC Interim Director Kevin Hamilton was interviewed by KITV weather anchor, Justin Fujioka, on global warming issues. Observed climate changes, projected global warming trends, the uncertainties in climate models, and our basic understanding of climate variability were topics of particular interest. The interview was aired in two stories on KITV 10 pm news.

Plastic pollution has formed "garbage patches" in some parts of the ocean. At the AGU Ocean Sciences meeting in Portland, IPRC Senior Scientist Nikolai Maximenko discussed at a press conference how knowledge of surface currents and ocean mixing are helping to understand where the plastic debris comes from and what happens to it once it enters the oceans more in National Geographic News, Science News, BBC News. Maximenko also released a model at the conference, the Surface CUrrent Diagnosis (SCUD) model, which will help in tracking ocean debris.
