#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.

Dublin Bay Sailing Club Turkey Shoot Winter Series

Dublin Bay Sailing Club's Turkey Shoot Series reached its 20th year in 2020.

The popular yacht series racing provides winter-racing for all the sailing clubs on the southside of Dublin Bay in the run-up to Christmas.

It regularly attracts a fleet of up to 70 boats of different shapes and sizes from all four yachts clubs at Dun Laoghaire: The National Yacht Club, The Royal St. George Yacht Club, The Royal Irish Yacht Club and the Dun Laoghaire Motor Yacht Club as well as other clubs such as Sailing in Dublin. Typically the event is hosted by each club in rotation.

The series has a short, sharp format for racing that starts at approximately 10 am and concludes around noon. The event was the brainchild of former DBSC Commodore Fintan Cairns to give the club year-round racing on the Bay thanks to the arrival of the marina at Dun Laoghaire in 2001. Cairns, an IRC racer himself, continues to run the series each winter.

Typically, racing features separate starts for different cruiser-racers but in fact, any type of boat is allowed to participate, even those yachts that do not normally race are encouraged to do so.

Turkey Shoot results are calculated under a modified ECHO handicap system and there can be a fun aspect to some of the scoring in keeping with the Christmas spirit of the occasion.

As a result, the Turkey Shoot often receives entries from boats as large as Beneteau 50 footers and one designs as small as 20-foot flying Fifteens, all competing over the same course.

It also has legendary weekly prizegivings in the host waterfront yacht clubs immediately after racing. There are fun prizes and overall prizes based on series results.

Regular updates and DBSC Turkey Shoot Results are published on Afloat each week as the series progresses.

FAQs

Cruisers, cruising boats, one-designs and boats that do not normally race are very welcome. Boats range in size from ocean-going cruisers at 60 and 60 feet right down to small one-design keelboats such as 20-foot Flying Fifteens. A listing of boats for different starts is announced on Channel 74 before racing each week.

Each winter from the first Sunday in November until the last week before Christmas.

Usually no more than two hours. The racecourse time limit is 12.30 hours.

Between six and eight with one or two discards applied.

Racing is organised by Dublin Bay Sailing Club and the Series is rotated across different waterfront yacht clubs for the popular after race party and prizegiving. The waterfront clubs are National Yacht Club (NYC), Royal Irish Yacht Club (RIYC), Royal St George Yacht Club (RSGYC) and Dun Laoghaire Motor Yacht Club (DMYC).
