Warming of Irish Lake Is Sign of Global Trend, Say Marine Scientists

#warmlkake – A lake in county Mayo is among a number of lakes around the world that are 'warming' and Irish Marine Scientists are part of a global research project examining the trend.

Data for Lough Feeagh, situated in the Burrishoole catchment in Co. Mayo, forms part of the data, and is one of a small number of lakes worldwide for which long-term temperature data are available.

A temperature recorder on Lough Feeagh was originally installed in 1960, when the Salmon Research Trust of Ireland began investigations into the movement of salmon, trout and eel through the catchment.

The magnitude and uniformity of the worldwide trend remains unclear but to facilitate research on this topic, a global database of summer temperatures for 291 lakes from 1859-2009 has been compiled, complemented by data on local climatic drivers and lake geomorphology.

The paper describing lakes as sentinels of climate change is published in the Journal of Scientific Data, by Nature (http://www.nature.com/sdata/) on the 17th March 2015. Dr Elvira de Eyto, Marine Institute and co author on the paper along with Marine Institute scientists are part of the Global Lake Temperature Collaboration (GLTC), an international group assembled to provide increased access to global lake temperature records.

The GLTC project recognised that a new global database of lake surface temperatures was needed, including not only satellite data, but also "on the ground" measurements from in situ data collection programs. Since its
inception in 2010, the GLTC initiative has grown to a database of 291 lakes and reservoirs worldwide, providing summer-mean lake surface temperatures from 1985-2009, and roughly doubling the amount of data previously available from satellites alone. This new dataset represents the first publicly available global compilation of in situ and satellite-based lake surface temperature data. The GLTC database also provides information on climatic drivers (air temperature, solar radiation, cloud cover), as well as geomorphometric characteristics that may affect lake temperature (latitude, longitude, elevation, lake surface area, maximum depth, mean depth, volume).
This unique, global dataset will offer an invaluable baseline perspective on lake thermal conditions for ongoing and future studies of environmental change. The Marine Institute continues this work, and maintains an extensive environmental monitoring programme in the catchment which is used to record climate and land use changes that may impact fish stocks.

Lough Derg Lifeboat Rescue Yacht Aground

Lough Derg Lifeboat assisted a person on board a 26ft–yacht after it grounded on a sand back north of Kilgarvin on Lough Derg On Thursday evening. Lough RNLI Derg lifeboat Toshiba Wave Warrior towed a 26ft yacht to safety after it agrounded as it tried to make for harbour.

At 18.37 the lifeboat launched with helm Colin Knight, Eleanor Hooker and Ger Egan on board. The lake was calm and with good visibility from the moonlight when night fell. The lifeboat came alongside the casualty vessel at 19.05hrs and found that the person on board was safe and unharmed. The lifeboat took soundings in and around the entrance to the private harbour and having decided that there was not sufficient depth for the draft of the vessel, took the vessel off the sandbar and then towed her to the safety of the public harbour of Kilgarvin Quay a short distance away.

The skipper of the vessel thanked the crew of the lifeboat. He said that he was 'very glad you came out, I was preparing myself to sit here all night'.

The lifeboat returned to station and was ready for service again at 20.50hrs

Stay Away from the Edge Warns Irish Water Safety

Irish Water Safety is asking people to keep away from the water's edge during the current violent storm force winds and high seas. Ireland averages 153 drownings every year and every year a number of tragedies occur as a result of people walking too close to the edge of coastal areas, cliffs, rivers and lakes during such stormy conditions.

Irish Water Safety is also asking those who own a small craft to make sure that it is well secured and when doing so, to wear a lifejacket at all times as there have been drownings during such activities in the past.

Motorists need to be particularly vigilant to avoid flooded areas on roads but particularly near rivers, because with poor light and short days it is not possible to determine the depth of floods easily. Swift water will carry cars and other vehicles away and there have been very tragic drownings in the past as a result of such accidents.

Children are naturally curious about water, therefore parents should caution them that floodwater hides the true depth and that manhole covers may be open and that small streams when swollen are very fast and deeper than normal.

What should I do when I hear a Flood Warning?
·                Listen to the national and local radio for met eireann updates and AA Road watch updates
·                Check on neighbours particularly if they are elderly, infirmed or families with young children
·                Move your vehicles to higher ground
·                Move animal stock to higher ground
·                Check your small craft to ensure they are well secured or moored
·                Make sure you have warm clothes, food, drink, a torch and radio.
·                Block doorways and airbricks with sandbags or plastic bags filled with earth. Floodgate products will work effectively also.
·                Switch off gas and electricity supplies if flooding is imminent.
·                Check the time of High Water in the Newspaper.
·                Check out www.flooding.ie for more detail on General flooding

Personal Safety
·                Avoid flood waters at all times
·                carry a mobile phone at all times in case you need to call for help - call 112 or 999 in emergency
·                Wear suitable protective clothing & a lifejacket in on or around water
·                Do not enter fast flowing water.
·                Never put your feet down if swept away by fast flowing waters
·                Flooding on roads will be deeper at dips and around bridges.
·                Stay away from sea and flood defences.
·                when walking or driving, be aware of manhole covers and gratings that may have been moved due to the heavy flow of water.
·                Take care when using electric appliances in damp or flood conditions.
·                Remember that during the hours of darkness the dangers are multiplied.

After the flood
·                Avoid eating food that has been in contact with flood water.
·                Run water for a few minutes and wash your taps.
·                Check gas and electricity supply.
·                Leave wet electrical equipment alone to dry and have it checked prior to use.
·                Ventilate your property well.
·                Check on elderly neighbours.

About The Middle Sea Race

The Rolex Middle Sea Race is a highly rated offshore classic, often mentioned in the same breath as the Rolex Fastnet, The Rolex Sydney–Hobart and Newport-Bermuda as a 'must do' race. The Royal Malta Yacht Club and the Royal Ocean Racing Club co-founded the race in 1968 and 2007 was the 28th Edition. Save for a break between 1984 and 1995 the event has been run annually attracting 25–30 yachts. In recent years, the number of entries has rissen sharply to 68 boats thanks to a new Organising Committee who managed to bring Rolex on board as title sponsor for the Middle Sea Race.

The race is a true challenge to skippers and crews who have to be at their very best to cope with the often changeable and demanding conditions. Equally, the race is blessed with unsurpassed scenery with its course, taking competitors close to a number of islands, which form marks of the course. Ted Turner described the MSR as "the most beautiful race course in the world".

Apart from Turner, famous competitors have included Eric Tabarly, Cino Ricci, Herbert von Karajan, Jim Dolan, Sir Chay Blyth and Sir Francis Chichester (fresh from his round the world adventure). High profile boats from the world's top designers take part, most in pursuit of line honours and the record – competing yachts include the extreme Open 60s, Riviera di Rimini and Shining; the maxis, Mistress Quickly, Zephyrus IV and Sagamore; and the pocket rockets such as the 41-foot J-125 Strait Dealer and the DK46, Fidessa Fastwave.

In 2006, Mike Sanderson and Seb Josse on board ABN Amro, winner of the Volvo Ocean Race, the super Maxis; Alfa Romeo and Maximus and the 2006 Rolex Middle Sea Race overall winner, Hasso Platner on board his MaxZ86, Morning Glory.

George David on board Rambler (ex-Alfa Romeo) managed a new course record in 2007 and in 2008, Thierry Bouchard on Spirit of Ad Hoc won the Rolex Middle Sea Race on board a Beneteau 40.7

The largest number of entries was 78 established in 2008.

Middle Sea Race History

IN THE BEGINNING

The Middle Sea Race was conceived as the result of sporting rivalry between great friends, Paul and John Ripard and an Englishman residing in Malta called Jimmy White, all members of the Royal Malta Yacht Club. In the early fifties, it was mainly British servicemen stationed in Malta who competitively raced. Even the boats had a military connection, since they were old German training boats captured by the British during the war. At the time, the RMYC only had a few Maltese members, amongst who were Paul and John Ripard.

So it was in the early sixties that Paul and Jimmy, together with a mutual friend, Alan Green (later to become the Race Director of the Royal Ocean Racing Club), set out to map a course designed to offer an exciting race in different conditions to those prevailing in Maltese coastal waters. They also decided the course would be slightly longer than the RORC's longest race, the Fastnet. The resulting course is the same as used today.

Ted Turner, CEO of Turner Communications (CNN) has written that the Middle Sea Race "must be the most beautiful race course in the world. What other event has an active volcano as a mark of the course?"

In all of its editions since it was first run in 1968 – won by Paul Ripard's brother John, the Rolex Middle Sea Race has attracted many prestigious names in yachting. Some of these have gone on to greater things in life and have actually left their imprint on the world at large. Amongst these one finds the late Raul Gardini who won line honours in 1979 on Rumegal, and who spearheaded the 1992 Italian Challenge for the America's Cup with Moro di Venezia.

Another former line honours winner (1971) who has passed away since was Frenchman Eric Tabarly winner of round the world and transatlantic races on Penduik. Before his death, he was in Malta again for the novel Around Europe Open UAP Race involving monohulls, catamarans and trimarans. The guest list for the Middle Sea Race has included VIP's of the likes of Sir Francis Chichester, who in 1966 was the first man to sail around the world single-handedly, making only one stop.

The list of top yachting names includes many Italians. It is, after all a premier race around their largest island. These include Navy Admiral Tino Straulino, Olympic gold medallist in the star class and Cino Ricci, well known yachting TV commentator. And it is also an Italian who in 1999 finally beat the course record set by Mistress Quickly in 1978. Top racing skipper Andrea Scarabelli beat it so resoundingly, he knocked off over six hours from the time that had stood unbeaten for 20 years.

World famous round the world race winners with a Middle Sea Race connection include yachting journalist Sir Robin Knox-Johnston and Les Williams, both from the UK.

The Maxi Class has long had a long and loving relationship with the Middle Sea Race. Right from the early days personalities such as Germany's Herbert Von Karajan, famous orchestra conductor and artistic director of the Berliner Philarmoniker, competing with his maxi Helisara IV. Later came Marvin Greene Jr, CEO of Reeves Communications Corporation and owner of the well known Nirvana (line honours in 1982) and Jim Dolan, CEO of Cablevision, whose Sagamore was back in 1999 to try and emulate the line honours she won in 1997.

THE COURSE RECORD

The course record was held by the San Francisco based, Robert McNeil on board his Maxi Turbo Sled Zephyrus IV when in 2000, he smashed the Course record which now stands at 64 hrs 49 mins 57 secs. Zephyrus IV is a Rechiel-Pugh design. In recent years, various maxis such as Alfa Romeo, Nokia, Maximus and Morning Glory have all tried to break this course record, but the wind Gods have never played along. Even the VOR winner, ABN AMro tried, but all failed in 2006.

However, George David came along on board Rambler in 2007 and demolished the course record established by Zephyrus IV in 2000. This now stands at 1 day, 23 hours, 55 minutes and 3 seconds.
