Unusual mechanism of the Ambrym and Pentecost Islands earthquake in Vanuatu
The Vanuatu island arc, in the South-West Pacific, is 1 700 km long. It corresponds to a convergence zone where the Australian plate is slipping eastwards under the North Fiji Basin, which is part of the Pacific plate, thus generating earthquakes. On 26 November 1999, the central islands of Vanuatu, particularly Ambrym and Pentecost, were strongly... view more... (2004-02-20)
From parasitism to mutualism: Partner control in asymmetric interactions
What prevents an exploitative individual from taking advantage of a cooperative partner? Most attempts to answer this question focus on reciprocity - exploitation may not pay, if it triggers retaliation. But in many encounters, only one individual can exploit the other. For example, when coral reef fish approach a `cleaner` wrasse to have their... view more... (2002-09-09)
What are coral reef services worth? $130,000 to $1.2 million per hectare, per year: experts
Experts concluding the global DIVERSITAS biodiversity conference today in Cape Town described preliminary research revealing jaw-dropping dollar values of the "ecosystem services" of biomes like forests and coral reefs - including food, pollution treatment and climate regulation. view more (2009-10-16)
Study links swings in North Atlantic Oscillation variability to climate warming
Using a 218-year-long temperature record from a Bermuda brain coral, researchers at the Woods Hole Oceanographic Institution (WHOI) have created the first marine-based reconstruction showing the long-term behavior of one of the most important drivers of climate fluctuations in the North Atlantic. view more (2009-01-14)
Time to tap climate-change-combating potential of the world's ecosystems
Investing in restoration and maintenance of the Earth's multi-trillion dollar ecosystems - from forests and mangroves to wetlands and river basins - can have a key role in countering climate change and climate-proofing vulnerable economies. view more (2009-09-02)
Expedition discovers marine treasures
An underwater mountain that forms the world's third-largest atoll has some of the richest diversity of marine life ever found in the Caribbean, according to scientists who recently explored the area. view more (2006-02-14)
CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically... view more...

Ancient climate secrets raised from ocean depths
Scientists aboard the research vessel, Southern Surveyor, return to Hobart today with a collection of coral samples and photographs taken in the Southern Ocean at greater depths than ever before. view more (2008-02-04)
Environmental lessons from tsunami as world's coastal population doubles
Coastal populations and ecosystems are more likely to bounce back from extreme coastal disasters by protecting local environments and building on local knowledge, according to a report published in Science. view more (2005-08-12)
Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage. view more (2007-11-07)
Was El Ni'得 unaffected by the Little Ice Age ?
An extremely intense El Ni'得 event in 1983 prompted an international surveillance programme, involving the deployment of moored or drift measurement buoys and observation satellites. This research effort is proving to be fruitful. The data obtained provide a key to understanding how the two components of the now-famous two-phase system El Ni'得... view more... (2002-03-27)
Giant squid killed by airguns in the Bay of Biscay? declining North Sea fish, cold-water corals and climate change.
This press release provides summaries of key papers being presented at the ICES Annual Science Conference in Vigo, Spain (22-25 September 2004). view more (2004-09-21)
Arctic, antarctic melting may raise sea levels faster than expected
Ice sheets across both the Arctic and Antarctic could melt more quickly than expected this century, according to two studies that blend computer modeling with paleoclimate records. view more (2006-03-24)
Freshwater supplies threatened in central Pacific
An international team from The Australian National University, Ecowise Environmental, the Government of the Republic of Kiribati, the French agency CIRAD and the Pacific Islands Applied Geoscience Commission has been studying the impacts of natural and human-induced changes on groundwater in the central Pacific nation of Kiribati since 1996. view more (2007-08-15)
Scientists look to the Bahamas as a model for coral reef conservation
One of the greatest challenges facing marine ecologists today is finding innovative ways to reverse the rapid decline of coral reef ecosystems around the world. view more (2006-02-21)
1 year after Solomon Islands, scientists learn barrier to earthquakes weaker than expected
On the one year anniversary of a devastating earthquake and tsunami in the Solomon Islands that killed 52 people and displaced more than 6,000, scientists are revising their understanding of the potential for similar giant earthquakes in other parts of the globe. view more (2008-04-03)
Microbialities: Indicators Of Environmental And Climatic Changes?
Microbial communities can adapt to and colonize all kinds of habitat, owing to their metabolic versatility. They occur in abyssal oceanic situations, in polar ice caps, also in thermal springs, lakes, rivers, deserts and on carbonate (karst) platform systems. Under favourable conditions, the microbial communities can proliferate and contribute to... view more... (2002-09-27)
Man-made crises 'outrunning our ability to deal with them,' scientists warn
The world faces a compounding series of crises driven by human activity, which existing governments and institutions are increasingly powerless to cope with, a group of eminent environmental scientists and economists has warned. view more (2009-09-11)
Combining sun, sand and science in the Bahamas
It is well known that people from all over the world come to the Bahamas to enjoy the pristine waters, spectacular coral reefs and great fishing. view more (2009-09-30)
What we can learn from the biggest extinction in the history of Earth
Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences. view more (2007-08-10)
