New 'seawater' -- the way ahead for ocean science
A proposed new definition of "seawater" is drawing the attention of the world's oceanographic community in a change that will advance the accuracy of climate science projections.

2008 AGU Fall Meeting
Abrupt climate shifts may move faster than thought
The United States could suffer the effects of abrupt climate changes within decades -- sooner than some previously thought -- says a new government report. It contends that seas could rise rapidly if melting of polar ice continues to outrun recent projections, and that an ongoing drought in the US west could be the start of permanent drying for the region.

Human connection to our nation's fisheries comes alive through oral history project
Voices from the Fisheries, an archive of oral histories of recreational and commercial fishermen and the communities and families that rely on them, documents the human experience with the nation's coastal, marine and Great Lakes environments and living marine resources. NOAA Fisheries social scientists have partnered with organizations around the country to create Voices as a clearinghouse for oral histories for the public and researchers and encourage the creation of new collections.

Catch the wave
MIT researchers are working with Portuguese colleagues to design a pilot-scale device that will capture significantly more of the energy in ocean waves than existing systems, and use it to power an electricity-generating turbine.

Some climate impacts happening faster than anticipated
A report released today at the annual meeting of the American Geophysical Union provides new insights on the potential for abrupt climate change and the effects it could have on the United States, identifying key concerns that include faster-than-expected loss of sea ice, rising sea levels and a possibly permanent state of drought in the American West.

New online report on massive jellyfish swarms released
Massive swarms of stinging jellyfish and jellyfish-like animals are transforming many world-class fisheries and tourist destinations into veritable jellytoriums that are intermittently jammed with pulsating, gelatinous creatures. Areas that are currently particularly hard-hit by these squishy animals include Hawaii, the Gulf of Mexico, the east coast of the US, the Bering Sea, the Mediterranean Sea, Australia, the Black Sea and other European seas, the Sea of Japan, the North Sea and Namibia.

Climate change alters ocean chemistry
Scientists have discovered that the ocean's chemical makeup is less stable and more greatly affected by climate change than previously believed. The researchers report in Science that during a time of climate change 13 million years ago, the chemical makeup of the oceans changed dramatically. The researchers warn that the chemistry of the ocean today could be similarly affected by climate changes now underway, with potentially far-reaching consequences for marine ecosystems.

Dissertation work on leading wave power
A technology that is adapted to the special conditions for wave energy places the wave energy technology from Uppsala on the absolute cutting edge in the world. In his dissertation, Rafael Waters presents the findings from the experimental facility located in the sea outside Lysekil, Sweden, in which he has played a leading role in designing and constructing.

Dune and dirty: Hurricane teaches lessons through ecosystem research
Dr. Rusty Feagin was managing several ecosystem research projects on Galveston Island when the 2008 hurricane season began. Then he got an unexpected visit from a research assistant named Ike. "Ike reconfirmed the basic idea I've had for several years," said Feagin, ecosystem scientist with Texas AgriLife Research. "The plants on sand dunes and in marshes build an island's elevation, so we shouldn't compromise that."

Palaeontology
Isopora or isn't it?
Scientists have made an unexpected discovery that links corals of the Pacific and Atlantic Oceans. Drs. Ann Budd and Donald McNeill named a new species of fossil coral found on the Island of Curaçao -- some 6 million years old -- after UM Rosenstiel School's Dr. Robert N. Ginsburg. The new species, originally thought to be an elkhorn coral was recently positively identified as a Pacific coral species with the help of Dr. Carden C. Wallace of the Museum of Tropical Queensland, Australia.

Rosenstiel School student wins honor at ocean forecasting symposium
Of 166 posters from around the world presented during the Global Ocean Data Assimilation Experiment in Nice, France, a poster submitted by UM Rosenstiel School Ph.D. student Rafael Schiller earned on of six coveted "Best Poster" Awards. The research was part of a collaborative effort supported by the Office of Naval Research, the National Ocean Partnership Program, the NOAA Cooperative Institute of Marine and Atmospheric Science and the NOAA Northern Gulf of Mexico Cooperative Institute.

ASU professor 'follows the elements' to understand evolution in ancient oceans
In the search for life beyond Earth, scientists "follow the water" to find places that might be hospitable. However, every home gardener knows that plants need more than water, or even sunshine. They also need fertilizer: a mixture of chemical elements that are the building blocks of the molecules of life. Scientists at Arizona State University are studying how the distribution of these elements on Earth -- or beyond -- shapes the distribution of life, the state of the environment and the course of evolution.

Bonefish census reveals population holding steady
If you're looking for bonefish from Miami down to the Marquesas , you have about 321,000 to choose from -- that is down slightly from the average of previous censuses. According to UM Rosenstiel School's Dr. Jerry Ault, co-founder of the census, statistically there is no significant difference year over year, which can be attributed to a variety of factors. This year 64 professional fishing guides, scientists and graduate students covered 1,575 square miles in the census of the Keys.

ESA satellites focusing on the Arctic
The Arctic is undergoing rapid transformation due to climate change, pollution and human activity. ESA's ERS and Envisat satellites have been providing satellite data of the region for the last 17 years. These long term data sets in combination with ESA's future missions will be key in implementing the newly adopted European Commission policy called "the European Union and the Arctic Region."
