Dolphin Sighting

As of 2001, 24 cetacean species have been recorded in Irish waters (Berrow, 2001) of which the Harbour Porpoise is the most common. This past summer has been a busy year for dolphin and whale spotters, most notably the three sightings of blue whale in recent weeks. In 1991 the Irish government declared all Irish waters, to the exclusive economic zone, a whale and dolphin sanctuary claiming that this was a “clear indication of Ireland’s commitment to contribute to the preservation and protection of these magnificent creatures in their natural environment, and to do everything possible to ensure they should not be put in danger of extinction but should be preserved for future generations” (Rogan and Berrow, 1995). Maybe someone in the whale and dolphin community has passed the word on to the Blue whales….

As the Irish Whale and Dolphin Group (IWDG) puts it:

‘To put this sighting into context, this is the 1st validated sighting of a blue whale in any Irish waters since the IWDG began almost 20 years ago. Although there was a single record of a sighting made by UCC personnel in the late 1990’s there are only two stranding records of blue whales on the Irish coast, the last of which was in Bantry Bay, Co. Cork in 1957, and then you have to go back to Magilligan Strand, Co. Derry in 1907.’

Our Sighting:

We spotted the dolphins in our video (we think that they’re Atlantic white-sided dolphins) east of Kedge Island, Baltimore, near the mouth of Lough Hine at the weekend. Saturday was a relatively calm day with good visibility and a light breeze. There were between 20 and 40 in the school and they breached the water with great gusto, continued bow riding the boat for up to 45 minutes until finally departing. In the first video you can see them at the start of the video and again at about 2:30 minutes in.

Many of the dolphins in our waters are feeding schools following shoals of fish, crustacea and other marine animals brought inshore by the Gulf stream. The Atlantic white-sided dolphin (Lagenorhynchus acutus) occurs inshore off the northwest in late summer and autumn and also occur occasionally in the Irish Sea. They have a white patch along the side with a prominent dorsal fin.

Again from the IWDG’s website:

‘This dolphin lives only in the northern North Atlantic and is restricted to temperate and sub-arctic areas, including the continental shelf, slope and deep canyons. The southern range for this species is Cape Cod and the mid-Atlantic canyons off the United States and the British Isles (sic) in the eastern Atlantic. It is known from well inside the Gulf of St. Lawrence, and off south Greenland, Iceland, and Norway, occasionally as far north as the Barents Sea. It has also been recorded in the North and Baltic Seas. While it has been stated that the white-sided dolphins have a more southerly distribution than white-beaked dolphins, the distribution of both overlap.’

The dolphin is a boisterous mammal which lives in schools ranging from a few tens to several thousands. In the video you can see they enjoy bow-riding the boat and seem to take great pleasure in it.

According to the IWDG: ‘This species is one of several species that has been taken in drives (a method of hunting dolphins by driving them together with boats and then usually into a bay or onto a beach) also involving pilot whales in the Faroe Islands. Incidental mortality in fishing gear has been documented off Canada, the US, the UK and Ireland. They appear particularly susceptible to capture in mid-water trawls. A juvenile dolphin from the northwest coast of Ireland was found to have a relatively high concentration of mercury in its liver. Moderately high levels of organochlorines have also been recorded.’

Sightings of Ceteceans can be reported to the IWDG here.

It’s unusual that Atlantic White Sided Dolphins would be recorded in this area as they tend to occur in more offshore waters and the continental shelf. According to the IWDG website they occur inshore off the northwest in late summer and autumn and also occur occasionally in the Irish Sea. We’ve been in touch with Dr Simon Berrow of the IWDG and we’re awaiting confirmation of our tentative identification. Other experts are welcome to comment below.

European Poker Tour

Right now over on EPT live, Galwayman Fintan Gavin has just made it to the last 6 (and is second in chips) at the European Poker Tour in Barcelona, top prize almost 1.4m. We’ll be tuned in for the day. Although one of the less well-known faces in international poker, Fintan is no novice and is our local poker facilitator…

We wish him the best of luck – and we’ll post updates later on.

As of 17:45 Fintan is not far off being chip leader, he’s knocked out Samuel Chartier and is well positioned to continue into the really big money. For his first ever entry in the EPT this is really a great achievement. Even if he’s knocked out now, which is unlikely, he stands to win almost 1/4m. 15 minute break now.

Fintan’s A 9 was enough to beat Chartiers K 10 to put Chartier out. But I’m sure he won’t be dissappointed with his €178,000 winnings.

18:10 – Play has restarted and we’re into a more exciting phase – the short stacks are under pressure and the blinds are bigger, so we should see some all-ins. Fintan still up there.

18:37: Fintan now chip leader, game hotting up…

19:15: Q Q and Fintan takes out Jason Mercier’s all in 7 7. Now well in the lead and minimum win of €227,000. What a game…

19:34: Dinner break for the players, Dinner break for us too.

20:29:Chip count as of now:

Fintan Gavin 2,530,000
Sebastian Ruthenberg 1,522,000
Dren Ukella 943,000
Davidi Kitai 662,000
Daniele Mazzia 572,000

21:17: Fint still 1m up on nearest player (Ruthenburg). He’s definitely confusing them… Ruthenburg the main competition thus far.

21:21: Now he’s taken Ukella out – final four. C’mon Fintan… From ETP:

Fintan raised to 130,000 and got a single caller in Dren Ukella. The flop came {10-Hearts} {9-Clubs} {2-Hearts}. Ukella checked over to Gavin and he led out for 200,000. Ukella paused briefly, then moved all in forcing Gavin to a major decision.

Gavin thought for about a minute or so before making the call. The players showed:

Gavin: {Q-Diamonds} {9-Hearts}
Ukella: {A-Hearts} {4-Hearts}

Gavin was in front with his middle pair, but Ukella has a flush draw and an overcard. He’d need them if he were to stay in the tournament. The turn brought the {7-Clubs} which was no help to either man. Ukella’s supporters were on their feet as the dealer put the {10-Diamonds} on the river. His ace high was not good enough and he exited in 5h place. Along with a great story, Ukella will take home € 292,000.

Fintan continues to dominate and is now sitting on almost 3 million chips – 50% of the entire table. Although his play is somewhat unconventional – it’s certainly a winning formula.  The commentators seem a little confused as to how his showing of cards has worked out and Mercier, in his commentary, mentioned that Fintan has numerous tells. But whether he has doesn’t seem to have made a big difference!

Over at ETP Fintan has fans:

Daniel O Shaugnessy (Galway): i love him

anto (dublin ireland): fintan is a legend

22:08: And then there were 3.

1 € 1,361,000
2 € 792,000
3 € 455,000
4 € 351,000 Daniele Mazzia

23:04: Fintan still leading.

Fintan – 3,477,000
Sebastian Ruthenberg – 1,636,000
Davidi Kitai – 999,000

23:23: Disclosure – For anyone wondering why an archaeological & environmental blog would live blog the EPT – Fintan is an in-law of one of Moore Group and a good friend. And I took him for €80 in poker on his stag – which means that I am a world beating poker player! Dec.

23:46: It’s heads-up Fintan and Guthenburg. It was always going this way.

Fintan – ‘I’m a fish’ – Here we go.

23:59: There we go. What a game. Fintan finishes second. There will be celebrations in Galway this week.

Well done Fintan!

Not the Large Hadron Collider, just a wheel

Here’s object number two in our virtual museum – a late medieval wheel from Galway City. As with the palstave, we’ve also presented a brief report on the find including a description of the circumstances of its finding.

Although it’s a somewhat less spectacular object, it’s one of those rare pieces which reflect everyday life in late medieval Galway, and as such has its own poignant significance.

As part of the Eyre Square Enhancement Project (Moore Group was engaged by Galway City Council as the consulting archaeologist on the project) the northern carriageway, including the old taxi rank, car park and casual trading area, was monitored and/or tested in advance by Billy Quinn of Moore Group.

The most significant discovery during the course of the excavations in this area was a peat deposit with obvious high archaeological potential. This feature is represented on the Pictorial Map of 1651 as a catchment area for water that developed into a ‘pool’ or ‘quagmire’ and was known by archaeologists to still be present in the area under the existing surface. The peat deposit had been cut by various service lines down through the years but remained largely intact. This peat deposit was found throughout the north of the square but was most evident towards the east in an area between Nos. 41-42 Eyre Square (Galway Advertiser office) and the old taxi rank.

Pre-development testing in advance of construction works had highlighted its existence and prior to the installation of a new 225mm diameter storm drain service trench a decision was made in consultation with the relevant people to preserve the layer in situ as much as possible. Permission was granted to mechanically excavate the trench but as a remedial measure, to prevent slippage and ensure minimum impact, the base and sides were covered in terram and backfilled immediately.

Discovery

The excavated fill was monitored and subsequently sifted through for finds and subsequently metal detected. The peat varied in depth from 1m to 2.5m and contained organic debris, animal bone, shell, leather fragments (including shoe soles) and sherds of post-medieval and medieval pottery. Metal detecting through the spoil was rewarded with the recovery of a small strand of gold gilt wire. This wire was probably intended for filigree ornamentation involving openwork of delicate or intricate design, a jewellery style popular in the late Nineteenth century.

A more pedestrian find but of equal note was that of a block carved wooden wheel and axle found within the peat near the western terminal of the old bus stop area. The wheel was found while digging a drain for a new gully.

Description

The wheel was carved from a single block of timber and measures 370mm in diameter by 73mm thick and could have been used for a cart or barrow. The wheel has a square section wooden axle through it, with ferrous dowels protruding from the centre at each end. The axle measures 72mm in diameter by 255mm long. Close to the wheel there are wooden dowels. There also appears to be the remains of roping around one end of the axle. Some tool marks are visible.

Condition

The wood is in very good condition and the wheel is complete with some minor superficial dirt. Some concretions have formed on the axle terminals and on the iron dowels.

Treatment

A gentle clean using fresh water was carried out by Arch-Con Labs in Dublin, followed by the impregnation of the wood with polyethylene glycols for 10 months, followed by freeze drying. Some minor surface treatment was carried out.

Conclusion

The Eyre Square enhancement scheme afforded us a unique, albeit keyhole, view of Galway’s late medieval – post medieval past. Given the practical constraints of development (not to mind the need for the City to continue functioning) a full archaeological excavation of the subject area was not feasible. Rather, archaeological mitigation involved the undertaking of an initial phase of targeted testing followed by archaeological monitoring, and where necessary excavation, to record finds, features and materials of significance as they were encountered during the course of the groundworks. As with any proposed development within an urban context and particularly one as central as Eyre Square the possibility of uncovering in situ archaeological deposits is of course relative to the degree of ground disturbance over time. In Eyre Square these impacts were considerable. Although the basic arrangement of the park and surrounding streets is recognizable from the 1651 map onwards, the actual topography of the area has changed significantly due to general re-development works involving ground reduction, infilling, road widening, resurfacings and the installation of an assortment of subterranean services.

Notwithstanding these incremental changes it was surprising how much archaeological material survived undisturbed. To the north of the square, excavations located the foundations of an eighteenth century market house (see here) which was exposed, recorded and retained in situ. The excavation of a trial pit to the north east of the market house also exposed an interesting stratigraphy of successive levels of the old road surface. These metalled layers marked the location of the market area leading east towards Prospect hill and beyond.

Whether the wheel was deliberately dumped in ‘the pool’ is impossible to determine. Although some may see it as a mundane and simple object, and perhaps it doesn’t have the immediate appeal or impact of, say, an Ardagh chalice, much of our archaeological heritage is similarly unspectacular or is invisible. Archaeology has been described as ‘the study of durable rubbish’ (to paraphrase Edwards & Anderson) and the wheel is one of those mute objects which doesn’t speak to us about the great and the good of the period. Nor does it tell us anything of the great upheavals of the time. Rather, it reflects the weary monotony of the workplace. Who knows? – perhaps its a long lost fragment of an Eyre Square traders barrow, or that of a tradesman or a fishmonger, discarded after the barrow finally fell apart, only to be found again several hundred years later, treated with polyethylene glycols, freeze dried and put on the internet!

Most of the time archaeologists must be content with merely helping to fill out the picture of the social world or daily life of the area in which they work and the wheel is just that – an unspectacular object demonstrating evidence of how people lived and the simple objects they used in late Medieval Galway.

The works at Eyre Square were financed by Galway City Council.
