Texas A&M researchers Tom Whitworth and Alex Orsi are designing a customized cyber-atlas for the Southern Ocean, combining historical and recent data to generate tailored maps. The atlas will utilize WOCE data to establish a global ocean baseline for studying decadal variability.
Scientists have developed a unique way to study elephant seals using tiny sensing devices attached to their coats. These devices provide valuable information on sea temperatures and pressure, even at depths not normally reached by research ships or satellite sensing.
Jonathan Scheuer, pioneer in marine natural products research, is being honored for his work on developing treatments for incurable diseases. His research has led to the discovery of compounds like Kahalalide F, a potential cancer treatment.
Scientists have found that the tropical Pacific Ocean played a key role in driving past ice ages, cooling by at least 3 degrees Celsius during each of the last five ice ages. This discovery challenges the long-held theory that high latitude and North Atlantic processes were the primary drivers of climate change.
Researchers have found a previously unknown oxygen-isotope signature in sulfate minerals on Earth, altering the understanding of the anomaly's origin. The discovery provides a new window into the Earth's ancient atmosphere and its cycling processes.
Two conferences will be held to present scientific findings on ocean issues, including fisheries, pollution, health, and gas hydrates. The events aim to develop a policy agenda for the US and internationally, with keynote speakers like Robert Ballard and Jean-Michel Cousteau.
Researchers at Brown University and the Marine Biological Laboratory have observed herpes simplex virus traveling from nerve endings to nerve cell bodies within living nerve cells. The discovery of a single transport mechanism could lead to better treatment options for potentially lethal viral infections.
Scientists discover a 1,800-year tidal cycle that matches recent climate change, suggesting a natural warming trend began a hundred years ago. The study suggests strong oceanic tides drive changes in climate by increasing vertical mixing, resulting in cooler climates and drought conditions.
A new MIT study analyzes the economic and atmospheric impacts of the Kyoto Protocol, showing that controlling multiple gases can greatly reduce costs. The research indicates flaws in the protocol's 'yardstick' for comparing greenhouse gases, highlighting the need for an integrated systems approach to mitigate climate change.
Researchers successfully eliminated an invasive South African worm that was causing deformed shells and stunted growth in California's abalone. By removing susceptible snails and using the 'epidemic threshold of transmission theory,' they were able to break the parasite's cycle, offering a new glimmer of hope for conservation efforts.
Researchers at UC Santa Barbara discovered a unique protein-based adhesive that explains the abalone shell's exceptional fracture resistance. This 'biological rubber' helps maintain its structure by releasing sacrificial links that break before the whole molecule, providing both strength and elasticity.
USGS scientists will present findings on prehistoric earthquakes, seismic hazards, and the structure of the Seattle basin. The presentations will provide insights into the probabilities for future earthquakes in the Seattle area and the current seismic hazards of the Pacific Northwest.
The Howard Hughes Medical Institute has awarded $1.32 million to Cold Spring Harbor Laboratory to support advanced courses in molecular biology, neuroscience, and structural biology. The institution will also construct a new teaching laboratory and provide scholarships for scientists worldwide.
The US Navy's USS HAWKBILL is conducting a five-week scientific expedition to the Arctic Ocean as part of SCICEX 99. The mission aims to examine geophysical, chemical, and biological properties of the Arctic Ocean, including mapping its poorly-charted floor.
The Deutsche Forschungsgemeinschaft has awarded the Eugen- and Ilse-Seibold Prize to Hans-Joachim Queisser and Yasuo Tanaka for their contributions to scientific studies in Japan and Germany. The prize promotes understanding between the two countries through fellowships and project funding.
Dr. Gerardo Vasta will discuss diseases in the ocean, including parasitic diseases affecting shellfish and fish species, which can harm human health and the environment. He will also highlight the importance of developing accurate probes for detection and monitoring of pathogens.
This book provides a thorough understanding of marine fish culture, including commercial production statistics, water treatment, rearing units, and nutrition for various species. With over 4,000 references, it is an essential resource for researchers, educators, and aquaculture professionals.
The University of Florida is part of a virtual Astrobiology Institute studying the origin and evolution of life in the galaxy. Chemists are searching for universal DNA features that could be found in potential Martian life, which may help overcome the difficulty of recognizing non-terrestrial life.
A geologist suggests that a comet impact that wiped out the dinosaurs may also be responsible for giant boulders found in Arkansas. The rocks were likely carried inland by a tsunami wave from the Gulf of Mexico and Caribbean.
The AAAS Annual Meeting brings together over 800 scientists and engineers to discuss groundbreaking research in various fields, including medicine, astronomy, and physics. Notable sessions cover topics like the influence of diet on breast cancer and the latest discoveries in astronomy.
A new volume of research explores the physical processes and interactions of Antarctic sea ice, shedding light on its differences from Arctic sea ice. The study highlights the importance of interdisciplinary approaches to understanding this complex environment, which is sensitive to climate change.
The American Geophysical Union Spring Meeting will feature presentations on earthquake hazards, ocean science, and Mars research. Scientists will discuss recent discoveries and share insights on natural restoration of contaminated aquifers.
Researchers at University of Washington identify decades-long climate shift in Pacific Ocean called PDO, influencing US West Coast ocean temperatures, winters, and salmon harvests. The current positive phase explains recent record highs in Alaska salmon and wetter winters in the South.
Researchers have identified the precise mechanism by which marine algae produce DMSP, a compound that helps clouds form in the atmosphere. This discovery could lead to genetically engineered crops with improved drought, freeze, and salt tolerance, potentially regulating global climate.
At the Seattle Science Meeting, USGS researchers will present on various topics including Martian exploration, integrated watershed studies, and geochemical backgrounds in Alaska and the Pacific Northwest. The meeting features several presentations by renowned scientists, including Dr. Michael Carr and Dr. David Howell.
Researchers discovered a cycle of strong and weak trade winds that triggered massive iceberg armadas across the North Atlantic during the last ice age. The study found a suborbital rhythm of 8,400 years in the strength of tropical winds, which governed the melting of massive ice sheets in the Northern Hemisphere.
Scientists found evidence of periodic changes in equatorial trade winds and warm tropical waters, which warmed the North Atlantic region and triggered melting along massive ice sheets. The research links climate phenomena at the top and middle of the globe, proposing a mechanism involving the release of warm water pools.
Sea Grant researchers are exploring various strategies to mitigate shipworm damage, a significant threat to marine ecosystems. The study aims to develop effective methods for reducing this type of damage and promoting sustainable coastal management.
