Extractions: B usiness O pportunities REGISTER HERE LOGIN URI Biological Oceanographers Test How Shallow Marine Systems Respond to Increased Nutrients Most of the efforts to determine how estuaries respond to nutrient enrichment have been confined to relatively deeper and/or muddier river mouth estuaries. However, much of the Atlantic coast from Cape Cod to Cape Fear, as well as parts of the Florida coast and almost all of the Gulf Coast is characterized by a different type of coastal system, called by various names, including lagoon, inland bay, and salt pond. These more complex shallow systems are now facing increasing nutrient enrichment from agriculture and suburban housing development with associated on-site sewage disposal systems and ground water nitrogen enrichment. A team of scientists at the URI Graduate School of Oceanography (GSO) have focused their research on these very shallow lagoon type estuaries to determine if there are predictable patterns of response to nutrient enrichment in these more complex systems. The research team includes biological oceanographer Dr. Scott Nixon, research associates Betty Buckley and Steven Granger, and recent Ph.D. graduate Joanne Bintz. According to a recent article in the journal Human and Ecological Risk Assessment, the scientific team summarized data from 30 systems with mean depths ranging from 1-12 feet and water residence times from .3-100 days. In addition the team designed and built a coastal lagoon mesocosm facility where they replicated and controlled nutrient inputs, mixing rates, and water resident time. Fed by water from Narragansett Bay, the mesocosms had a variety of typical coastal lagoon organisms added to them, in addition to the plankton that enter with the bay water and the animals contained in the sediment.

Extractions: Oceanographers use naturally occurring radium to measure ground water input to Rhode Island salt ponds In a recent study, reported in the Journal of Environmental Radioactivity, Scott and Moran collected and analyzed water samples from Rhode Island salt ponds and several local residential drinking wells, as well as sediment cores from each pond to determine how much 226Ra was present in the water and sediments. The radioactive element radium was discovered in 1898 by Marie and Pierre Curie in pitchblende (or uraninite) from North Bohemia. It is commonly used to make self-luminous paints, as a neutron source, and for the treatment of conditions such as cancer. It is a white alkaline earth metal that tarnishes black upon exposure to air. It luminesces, decomposes in water, emits radioactive radon gas, disintegrates radioactively until it reaches stable lead, and is a radiological hazard. With a half-life of 1,600 years, radium is more than a million times more radioactive than the same mass of uranium ( http://www.webelements.com/
Oceanographers Say Dead Whales Provide Deep-Sea Living Legacy

Smith, Dan Distel, Amy Baco and other individuals have found that whale bones, along with sunken wood, could be a missing link in the introduction of new species near deep-sea vents, which can reach high temperatures and spew a chemical soup that many organisms find intolerable. The researchers' results will be published in the Feb. 17 issue of the journal Nature Smith and his colleagues are intrigued by the creatures that are attracted to whale corpses. One organism, a big, orange polychaete worm that looks like a furry centipede, can be found in such numbers around whale skeletons that one researcher says it looks like the bones are covered with a orange shag carpet. But scientists have yet to learn how these worms arrive at the carcasses, where they come from, and what their role is in consuming the massive amounts of organic material - often more than 30 tons - found in a whale fall. Smith has studied two natural whale falls and three that were experimentally planted off the coast of southern California. Using a

Extractions: on Bay marine health and high school science education San Francisco, C.A., October 18 A delegation of high-ranking scientists from Chinaís top marine research institutions are meeting this week with researchers from San Francisco State Universityís Romberg Tiburon Center for Environmental Studies (RTC) to kick-off a ground-breaking science and education partnership. The five-year Cooperative Marine Education and Research Program (CMERP) between Chinaís Ocean University and San Francisco State University will bring together marine researchers and science educators to address two issues: the health of bay ecosystems, and high school science education. California and China both have large, complex bays which are fed by major riversóthe Sacramento River and the Yellow River, respectively. Located near major agricultural centers, both regions suffer the impact of large-scale irrigation and agricultural run-off, which changes the ecology of the mouths of these bays, called estuaries, where the fresh-water rivers drain into the ocean. In light of sharing similar environmental problems, the scientists believe that collaborating on research will help address the myriad problems facing these similar ecosystems. "The point of our collaboration is that we are all linked by the Pacific Ocean," said Dr. Jim Kelley, dean of SFSUís College of Science and Engineering. "The water that flows along our coast in the California current will, in a few months, be flowing along the coast of China, then back again. We hope that by working together we can better understand this shared marine system, while also bringing a new educational perspective to San Franciscoís classrooms."

Extractions: NEWS By VINCENT KIERNAN Columbia University oceanographer Arnold Gordon had planned to spend much of this year plumbing the Straits of Indonesia to understand how warm water from the Pacific Ocean mixes with the cooler waters of the Indian Ocean. His field work, financed by a $4.4 million grant, from the National Science Foundadon, would have been part of a five-year study to understand how differences in water temperature affect global weather patterns. But three years after Gordon first traveled to Jakarta to sketch out the project with his Indonesian collaborators, he has yet to collect any data; in fact, hes lost his grant. Instead of learning more about ocean currents, Gordon has been taught a bitter les son in international law. The source of his misery is a provision in a seven-year-Old international treaty which has not yet gone into effectthat allows nations to control access to their coastal waters. What happened to Gordon was that Indonesian officials, for reasons of their own, decided to use the proposed agreement as an excuse to stall the project. Every time Gordon sought permission to carry out the he was ignored.

Extractions: LEADERS OF SCIENCE By LAUREL JOYCE In 1914, an ambitious trans-antarctic expedition was organized by scientist/explorer Ernest Henry Shackleton. But during the middle of winter, his ship, the Endurance, was caught and crushed in the pack ice of the Weddell Sea. It wasnt until 1988 that another ship ventured into that part of the ocean during the antarctic winter, this time with the goal of studying the delicate and complex food web of the regions ice-edge zone, where the frozen and open ocean meet. Thoughts of Shackletons misfortunes may have flashed through the minds of some of the researchers on the National Science Foundations 210-foot research vessel Polar Duke each time they got stuck in the pack ice earlier this year. But on every occasion, they successfully freed the ship. And the hearty multidisciplinary team of oceanographers also made some unanticipated discoveries about the fragile polar ecosystem. During a 70-day research expedition conducted from June to August, the heart of the antarctic winter, the 47-member team of biological, chemical, and physical oceanographers from research institutions throughout the U.S. discovered high concentrations of tiny plants and animals that thrive throughout the winter within the pores of the sea ice. Perhaps the most significant find: the presence of krilla tiny shrimp-like crustacean that is an important food source for whales, seals, and penguinsat concentrations denser than ever before measured.

Extractions: Dr. Ian MacDonald will lead the mission and use a laser scan system to produce high-resolution pictures of the shipwreck and of the natural oil and gas seeps. The scanner can cover a larger area than traditional cameras and allow scientists to see individual animals, rocks and seashells. "It turns out that instead of inhibiting marine growth, the oil and gas creates a chemical enrichment of the seafloor which life is able to exploit," MacDonald said. The scientists will use the laser scanner to get an idea of the size of these communities an opportunity that MacDonald said scientists rarely have for marine ecosystems. "If we can get those estimates, then we can begin to model the entire ecosystem with greater precision than is normally possible," he said. MacDonald and Sager also will profile the different layers of sediment that make up the seafloor using a "chirper" SONAR system. By looking at the sediments, MacDonald said, they get a better idea of how much oil and gas is being released and the extent of gas hydrates solid mounds of natural gas and water that are found in and on the seafloor. The submarine also may stop off at the USS Monitor, the Civil War ironclad located in 230 feet of water off Cape Hatteras, N.C. Famous for its 1862 battle against the USS Merrimack, the Monitor sank later that year during rough seas. Recently, efforts have been made to preserve the ship's remains.

Extractions: Researchers have measured a further rise in sea surface temperature in the central tropical Pacific. ("Earthweek - A Diary of the Planet", The Toronto Star, 27 October 1990). The El Nino Southern Oscillation (ENSO) is a climatic phenomenon which influences the entire global climate system. The term refers to two closely linked states, the classic ENSO, commonly know as El Nino, associated with warm events, and the opposite extreme, anti-ENSO, commonly called La Nina, associated with cold events. ENSO events usually occur every two to ten years and generally last up to 18 months. They are characterised by a weakening or reversal of the easterly trade winds, a warming of the waters of the eastern Pacific and the switching of the see-sawing atmospheric pressure between the eastern and western Pacific (called the Southern Oscillation). Anti-ENSO events are generally associated with anomalies that are the opposite to those linked to ENSO; a strengthening of the trade winds and a cooling of waters in the eastern Pacific. ENSO events result in climatic changes throughout the world, in particular drought in southern Africa, Brazil and Australasia, and floods in the countries bordering the eastern Pacific. Anti- ENSO events generally involve phenomena which mirror those of ENSO; floods in Australasia for example. Currently, our understanding of ENSO is limited. Leading Australian climatologist Professor Ann Henderson-Sellers, suggests that ocean warming may unbalance the constant swing from ENSO to anti-ENSO. She speculates that ENSO may become the normal climate state and anti-ENSO the unusual event. (A.Henderson- Sellers and R. Blong, "The Greenhouse Effect. Living in a Warmer Australia," New South Wales University Press, 1989).
