Food choices and location influence California sea otter exposure to disease
Sea otters living along the central California coast risk higher exposure to disease-causing parasites as a consequence of the food they eat and where they feed. view more (2009-01-20)
NOAA, USFWS study finds potential disease threats to Washington sea otters
Many of Washington State's sea otters are exposed to the same pathogens responsible for causing disease in marine mammal populations in other parts of the country. view more (2009-05-07)
Sea otter study reveals striking variability in diets and feeding strategies
Ecologists have long observed that when food becomes scarce, animal populations exploit a wider range of food sources. view more (2008-01-15)
Shift in bald eagle diet linked to sea otter decline
A newly published study has found that the decline of sea otters along Alaska's Aleutian Islands has forced a change in the diet of a terrestrial predator - the bald eagle. The study demonstrates the extraordinary complexity of marine ecosystems and how far-ranging the impacts can be when there is a population shift in a keystone species like the... view more...

Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters
Seventeen years after the Exxon Valdez ran aground in Alaska's Prince William Sound, compelling new evidence suggests that remnants of the worst oil spill in U.S. history extend farther into tidal waters than previously thought, increasing the probability that the oil is causing unanticipated long-term harm to wildlife. view more (2006-05-16)
Decline in Alaskan sea otters affects bald eagles' diet
Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse. view more (2008-10-03)
Animal athletics: the benefits of being short
Could your dog win an Olympic race? Scientists at the University of California, Santa Cruz, USA, have been comparing limb shape with athletic performance in a range of animals to determine who makes the best athlete. At the Society for Experimental Biology meeting on Tuesday 3 April, Dr Terrie Williams of the University of California will present... view more... (2001-04-03)
Abalones along Pacific coast may owe their huge, dinner-plate size to sea otters
Abalone divers, who typically despise the California sea otter because of its voracious appetite for the largest and tastiest of the shellfish, may actually have otters to thank for the dinner-plate size of the prized delicacy. view more (2005-11-10)
Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals that help plants reproduce. Predation on pollinators... view more... (2003-08-13)
State of the steric sea level rise, 1955-2003
Based on a detailed analysis of ocean vertical temperature profiles for the 1955-2008 period, Sydney Levitus, lead author, talks about the change of global average sea level induced by the observed warming of the world ocean during the past 53 years. view more (2009-02-17)
Arctic sea ice reaches lowest extent in 2008, second lowest ever recorded
The Arctic sea ice cover appears to have reached its minimum extent for the year, the second-lowest extent recorded since satellite record-keeping began in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center, or NSIDC. view more (2008-09-17)
Arctic sea ice narrowly missed record low in winter 2007, says University of Colorado team
The maximum extent of Arctic sea ice in winter 2007 was the second lowest on satellite record, narrowly missing the 2006 record, according to a team of University of Colorado at Boulder researchers. view more (2007-04-05)
New Antarctic seabed sonar images reveal clues to sea-level rise
Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise. view more (2009-05-05)
Evolving From Marine Nature Reserves Towards Biotechnoparks
In near future, marine nature reserves will execute an important historic mission: they will become the crystallisation centres, around which territories should appear to perfect optimal methods for protection and utilization of maritime resources. Such conclusion was made by the leading preserving specialists, invited by WWF and the Moscow UNESCO... view more... (2003-12-05)
Changes in Ocean Circulation Could Lead To Rapid Regional Sea Level Change
One of the major consequences of future ocean circulation changes would be sea level change. This is shown in a new study by scientists from the Potsdam Institute for Climate Impact Research in Germany which was published in the recent issue of "Climate Dynamics". They investigated the scenario of a possible shutdown of the Atlantic overturning... view more... (2005-04-04)
Arctic sea ice reaches minimum extent for 2009, third lowest ever recorded
The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. view more (2009-09-18)
Artificial night lighting jeopardises the survival of sea life
Artificial night lighting can jeopardise the survival of sea turtles by obliterating environmental cues. Writing in the August issue of Biologist, Mike Salmon, of Florida Atlantic University, USA, explains how artificial coastal lighting disturbs female sea turtles' navigation to nest beaches and disorientates their hatchlings so that many fail to... view more...

Warming oceans threaten Antarctic glaciers
Scientists have identified four Antarctic glaciers that pose a threat to future sea levels using satellite observations, according to a study published in the journal Science. view more (2007-03-16)
The world's deepest dinosaur finding-2256 metres below the seabed
The somewhat rough uncovering of Norway's first dinosaur happened in the North Sea, at an entire 2256 metres below the seabed. It had been there for nearly 200 million years, ever since the time the North Sea wasn't a sea at all, but an enormous alluvial plane. view more (2006-04-25)
Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week. Researchers from the Cambridge-based British Antarctic Survey (BAS) reviewed the best available data from a range of long-term studies to test the view that warming of the Earth`s climate is... view more...
