#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DDTTAS) advises that Polarcus DMCC is scheduled to carry out a 3D seismic survey in the Porcupine Basin, southwest coast of Ireland, in early September.

The survey will cover 633 sq km and is is expected to last for around 20 days, subject to weather.

The seismic vessel M/V Polarcus Amani (Call sign C6ZD3) is scheduled to carry out the work. The vessel will be towing 10 cables, each 8.1km long with 150m separation at depth of 14 metres, with a total array width of 1.35km.

A buoy equipped with a radar reflector and navigation strobe light will be deployed at the end of each cable.

The seismic vessel will be accompanied by support vessel M/V Bravo Sapphire (Call sign ZDJY8) and chase vessel M/V Nomad (Call sign EI5298). All work vessels will be listening on VHF Channels 16 and 67.

The seismic vessel in particular will be restricted in its ability to manoeuvre while carrying out the survey so all vessels, particularly those engaged in fishing, are requested to give the M/V Polarcus Amani, her towed equipment, the M/V Bravo Sapphire and the M/V Nomad a wide berth and keep a sharp lookout in the relevant areas.

Co-ordinates for the proposed seismic 3D survey are included in Marine Notice No 52 of 2014, a PDF of which is available to read or download HERE.

Forty Foot Swimming Spot on Dublin Bay

The 'Forty Foot' is a rocky outcrop located at the southern tip of Dublin Bay at Sandycove, County Dublin from which people have been swimming in the Irish Sea all year round for 300 years or more. It is popular because it is one of few spots between Dublin city and Greystones in County Wicklow that allows for swimming at all stages of the tide, subject to the sea state.

Forty Foot History

Traditionally, the bathing spot was exclusively a men's bathing spot and the gentlemen's swimming club was established to help conserve the area.

Owing to its relative isolation and gender-specific nature it became a popular spot for nudists, but in the 1970s, during the women's liberation movement, a group of female equal-rights activists plunged into the waters and now it is also open to everyone and it is in the control of Dun Laoghaire Rathdown County Council.

Many people believe that swimming in extremely cold water is healthy and good for the immune system.

Is it safe to swim at the Forty Foot?

The Forty-Foot is a great place to swim because there is always enough water to get a dip but like all sea swimming, there are always hazards you need to be aware of.   For example, a lot of people like to dive into to the pool at the Forty-foot but there are submerged rocks that can be hazardous especially at low water.  The Council have erected signs to warn people of the underwater dangers. Other hazards include slippy granite cut stone steps that can often be covered with seaweed and of course marine wildlife including jellyfish that make their presence felt in the summer months as do an inquisitive nearby Sandycove seal colony.

The Forty-foot Christmas Day swim

A Dublin institution that brings people from across Dublin and beyond for a dip in the chilly winter sea. Bathers arrive in the dark from 6 am and by noon the entire forty foot is a sea of red Santa hats!
