Lawrence LeBlond for redOrbit.com - Your Universe Online Researchers publishing a paper in the latest issue of the journal Science have found through Antarctic planktonic ice core examinations that the continental ice cap formed more than 33 million years ago. Scientists from the Andalusian Institute of Earth Sciences (IACT), a joint collaboration between the University of Granada and the Spanish National Research Council (CSIC), said the seasonal primary productivity of planktonic...

redOrbit Staff & Wire Reports - Your Universe Online The development of the sea-ice ecosystem in the circum-Antarctic Southern Ocean may have triggered further adaptation and evolution of larger organisms such as baleen whales and penguins, according to a new study published Thursday in the journal Science. The area´s ecosystem can be traced back to the emergence of the Antarctic ice sheets some 33.6 million years ago and plays an important role in global marine food webs and...

Potential mechanism for dazzling blue flashes of light in oceans identified It has long been known that distinctive blue flashes--a type of bioluminescence--that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates. However, a new study has, for the first time, detailed the potential mechanism for this bioluminesence. The study, which was partially funded by the National Science Foundation, is reported by Susan Smith of Emory...

Red tides and similar blooms can render some seafood unsafe to eat, though it can be difficult to tell whether a particular batch harbors toxins that cause food poisoning.A new kind of marker developed by chemists at the University of California, San Diego, and reported in the journal ChemComm makes it easier to see if shellfish are filled with toxin-producing organisms.Mussels and oysters accumulate single-celled marine creatures called dinoflagellates in their digestive systems as they...

The origin of the neurotoxin azaspiracid has finally been identified after a search for more than a decade. The azaspiracid toxin group can cause severe poisoning in human consumers of mussels after being enriched in the shellfish tissues. The scientific periodical European Journal of Phycology reports in its current issue (Vol. 44/1: p. 63-79) that a tiny algal species, the dinoflagellate Azadinium spinosum, is responsible. Researchers from the Alfred Wegener Institute for Polar and Marine...
