#MarineLife - Scientists from Russia say they have found a new form of bacterial life in Antarctic water cut off from the surface for millions of years, as BBC News reports.

The research team at Vostok, the largest subglacial lake on the continent of Antarctica, are studying samples of bacteria from water released after drilling through some 4km of ice to the lake beneath.

The body of water at Vostok is believed to have been isolated for so long that the possibility of it hosting microbial life new to science is high - and scientists say their initial findings are promising.

"We are calling this life form unclassified and unidentified," said geneticist Dr Sergei Bulat of the St Petersburg Institute of Nuclear Physics, who added that one particular form of bacteria has DNA less than 86% similar to known strains.

"A level of 90% usually means that the organism is unknown," he said.

These astounding new findings are however pending verification by other experts before any confirmation can be made.

The Inland Waterways Association of Ireland (IWAI) has confirmed a number of reports of dead swans found along the Grand Canal in south Dublin.
IWAI representative Colin Becker said some of the dead birds were taken away for analysis, while a number of sick birds were taken for treatment by the DSPCA.
As of yesterday morning "another half dozen" deceased swans were discovered between Portobello Harbour and Suir Road Bridge.
Initial reports are pointing to a form of botulism or other bacterial infection. No source had yet been pin-pointed but "a number of dead and rotting sea-fish were found in the area", according to Becker.
He added that swans are known to be susceptibe to bacterial infections.
The IWAI ruled out the presence avian flu, and dismissed suggestions that dredging of the canal might have disturbed bacteria in the sediment, as the infected swans were found some distance from the current dredging site.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
