- Fisheries should be regarded as a part of the maritime environment
12-20-2007 · EurekAlert!
Professional fishery is in many sea areas a serious ecological threat to the maritime environment. On the other hand, changes in the environment, e.g. the increase of fish-eating animals like seals and cormorants, may impact the fisheries. One of the new guiding principles of political decision-making in fishery issues is that a holistic "ecosystems approach" should be used instead of traditional protection of fish populations.

- Hydrothermal vents: Hot spots of microbial diversity
10-04-2007 · EurekAlert!
Thousands of new kinds of marine microbes have been discovered at two deep-sea hydrothermal vents off the Oregon coast by scientists at the MBL and University of Washington's Joint Institute for the Study of Atmosphere and Ocean. Their findings, published in the Oct. 5 issue of the journal Science, are the result of the most comprehensive, comparative study to date of deep-sea microbial communities that are responsible for cycling carbon, nitrogen, and sulfur to help keep Earth habitable.

- Map is first to track global human influences on ocean ecosystems
02-14-2008 · EurekAlert!
The first global map of human influences on marine ecosystems has been constructed by a team of researchers, including a Stanford University scientist among the principal investigators, by gathering and interpreting massive amounts of data from the professional literature and from researchers around the world. This study suggests that about 41 percent of oceans bear a serious human "footprint " and that few blue spots on our planet are likely pristine.

- Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward
02-15-2007 · EurekAlert!
The warming most global climate models predict will do more harm than simply raise the sea levels that most observers fear. It will make drastic changes in fragile ecosystems throughout the world, especially in the Antarctic. A warming trend during the last few decades in the Antarctic Peninsula has already forced penguin populations to migrate south and perhaps diminished the abundance of krill that are at the base of the massive food chain at the bottom of the world.

- Scientists discover new life in the Antarctic deep sea
05-16-2007 · EurekAlert!
Scientists have found hundreds of new marine creatures in the vast, dark deep-sea surrounding Antarctica. Carnivorous sponges, free-swimming worms, crustaceans, and molluscs living in the Weddell Sea provide new insights into the evolution of ocean life.

- EuroNews looks at monitoring the changing environment
01-25-2008 · European Space Agency (ESA)
Signs of a warming climate are already being felt in the icy reaches of the Arctic. The consequences of diminishing sea-ice are far-reaching - affecting the peoples and wildlife reliant on this fragile ecosystem, global climate and even international shipping routes. EuroNews looks at how ESA satellites are an invaluable aid to monitoring this changing environment.

- Study finds oysters can take heat and heavy metals, but not both
12-13-2006 · EurekAlert!
Could low-level heavy metal pollution be combining with warm water temperatures to fatally weaken sea life? A study examining the joint effects of cadmium and temperature on mitochondrial metabolism in oysters finds a combined effect that is potentially lethal and could be a significant contributor to recent oyster declines. The research has broad implications for cold-blooded marine organisms.
