St Patrick’s day Swim for RNLI - just keep finning 🏊‍♀️

13/12/2023

In 2022 Scientists have found and filmed one of the greatest ever undiscovered shipwrecks 107 years after it sank. The Endurance, the lost vessel of Antarctic explorer Sir Ernest Shackleton, was found at the weekend at the bottom of the Weddell Sea.

The ship was crushed by sea-ice and sank in 1915, forcing Shackleton and his men to make an astonishing escape on foot and in small boats. Even though it has been sitting in 3km (10,000ft) of water for over a century, it looks just like it did on the November day it went down. Its timbers, although disrupted, are still very much together, and the name - Endurance - is clearly visible on the stern.

"Without any exaggeration this is the finest wooden shipwreck I have ever seen - by far," said marine archaeologist Mensun Bound, who is on the discovery expedition and has now fulfilled a dream ambition in his near 50-year career.

KILMORE QUAY MINI TSUNAMI OF 1854

William Campbell, known locally as ‘The Diver’, was working on the building of the new pier in Kilmore Quay on the evening of 16 September 1854. It would replace a makeshift one built of loose rocks by local fishermen that dated from the late 1780s. William was in one of four boats employed in the construction work. While fetching an implement and facing away from the sea, he “heard a mighty rush of water against the back of the pier, and in a moment came sweeping around the pier head, full three feet high and abreast,” he told the Wexford Independent.

William said this ‘extraordinary phenomenon’ occurred an hour and thirty minutes following low tide. The shoreline was dry and crowded with small sailing craft. Within five minutes every boat was afloat on a high tide. The water receded again five minutes later to an extremely low spring tide. This occurrence repeated itself seven times in the course of two and a half hours.

William recalled: “Standing on the top of the parapet wall of the pier, I could descry two different currents running parallel, and counter currents to these quite visible, the discoloured water running east at a rate of ten or twelve miles an hour, and the intervening water, of the original green hue, as is stationary. These tide currents were as far as the shore of the Saltee Islands. I can only compare the current to the opening of a sluice gate.”

None of the boats tied up near the shore was damaged apart from a few becoming untethered and being pushed aground. Had the occurrence taken place during high tide, this low-lying district would have been submerged, resulting in great losses. In the Belfast Newsletter account of the event, it was noted that: “It was a fortunate matter that the event happened late in the day, as, had it occurred in the morning, the many bathers who frequent the bathing-places on the coast must inevitably have been drowned.”

The newspaper speculated that this phenomenon may have been caused by an earthquake in some distant land. It was remembered that there had been a similar occurrence in the area almost hundred years previously on the day after the Lisbon earthquake of 1 November 1755. That event was one of the deadliest earthquakes in history. It almost totally destroyed the city of Lisbon, lying due south of Ireland, and resulted in between 30,000 and 40,000 deaths in Lisbon alone. Approximately forty minutes after the earthquake, a tsunami flooded the city as well as towns along the Algarve coast. A firestorm in Lisbon was started by candles – lit in homes and churches all around the city for All Saints’ Day – being knocked over and asphyxiating thousands of its citizens. The Spanish Arch in Galway city was partially destroyed and Kinsale was flooded. Aughinish Island in County Clare was created when a low-lying connection to the mainland was washed away.

But no earthquake was recorded in the Atlantic in September 1854. In the ‘Earthquake Catalogue’, published in two volumes by the British Association for the Advancement of Science in 1858, the event witnessed in Kilmore Quay was recorded and described, along with a map, as a probable tsunami.
