The onshore gas processing terminal at Point of Ayr. It runs northwest-southeast between Scotland and Northern Ireland and includes the larger Arran and Gigha islands and the smaller Ailsa Craig, on each of which a lighthouse is located. What is the world’s largest inland sea? The basin comprises a south-easterly deepening half-graben near the Welsh coastline, although its internal structure becomes increasingly complex towards the southwest. The enormous basking shark, for example, lives entirely on plankton and the leatherback turtle's main food is jellyfish. Region 13 Northern Irish Sea: Irish Sea Study Group Report, Part 1, Nature Conservation, Liverpool University Press, 1990. This series of sea angling maps was developed by the Promotion and Marketing staff of the CFB in the 1980’s. The Irish Sea is of significant economic importance to regional trade, shipping and transport, as well as fishing and power generation in the form of wind power and nuclear power plants. sea routes weather routing voyage planning vessels ships ports shipyards bunker consumption tide stations Calculate distances - nautical miles or kilometers for seagoing ships and vessels.

The region covered by this Report is Area 6, the Irish Sea, defined as 51–55.6 degrees North, 2-6.5 degrees West. The Irish Sea's shallow water and strong winds make for an excellent supply of wind for wind farms offshore. Share page. In the UK, the heaviest seafood consumers in Cumbria received a radioactive dosage attributable to Sellafield discharges of 220 Î¼Sv (0.022 rem) in 2005. Previous exploration drilling in the Kish Bank Basin has confirmed the potential for petroleum generation with oil shows seen in a number of wells together with natural hydrocarbon seeps recorded from airborne surveys. Fleetwood, lying north of Liverpool, is the chief British fishing port, and Ardglass, Portavogie, and Kilkeel are important in Northern Ireland. The Caernarfon Bay basin contains up to 7 cubic kilometres (1.7 cu mi) of Permian and Triassic syn-rift sediments in an asymmetrical graben that is bounded to the north and south by Lower Paleozoic massifs. The most likely hydrocarbon source rocks are Early Jurassic marine mudstones. Analysis[34][35] of the distribution of radioactive contamination after discharge reveals that mean sea currents result in much of the more soluble elements such as caesium being flushed out of the Irish Sea through the North Channel about a year after discharge. Irish Sea, Irish Muir Éireann, arm of the North Atlantic Ocean that separates Ireland from Great Britain. 2) Definition of topic. This is a list of islands in the Irish Sea.

Irish Sea Bridge: Boris Johnson puts ... say it will be possible to build it with a tunnelled section to cope with some of the difficulties caused by the depth of the Irish Sea. Permian to Triassic, syn-rift sediments within the basin are less than 3 km (1.9 mi) thick and are overlain by up to 4 km (2.5 mi) of Jurassic strata, and locally also by up to 2 km (1.2 mi) of Paleogene fluvio-deltaic sediments. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. The Cardigan Bay Basin was subjected to two Tertiary phases of compressive uplift, whereas maximum burial that terminated primary hydrocarbon generation was probably around the end of the Cretaceous, or earlier if Cretaceous strata, now missing, were never deposited in the basin. The challenge for the Irish market is to develop more FCL/FTL loads. IRISH SEA. 14 August 2013. Where is the Puerto Rico Trench? Huge populations of the sea duck, common scoter, spend winters feeding in shallow waters off eastern Ireland, Lancashire and North Wales.[25]. Crustaceans, especially copepods, dominate the zooplankton. Folio 6 N & E Coast Scotland, Orkney & Shetland. [42], Discussions of linking Britain to Ireland began in 1895,[43] with an application for £15,000 towards the cost of carrying out borings and soundings in the North Channel to see if a tunnel between Ireland and Scotland was viable. Coasts and seas of the United Kingdom. It comprises the integrated development of five offshore oil and gas fields in the Irish Sea: Oil is produced from the Lennox and Douglas fields. [44] A tunnel project has been discussed several times in the Irish parliament. Tidal streams enter the Irish Sea from both the north and the south, meeting near latitude 54° N, just south of the Isle of Man. Discharges of technetium in particular rose from 6.1 TBq (160 Ci) in 1993 to a peak of 192 TBq (5,200 Ci) in 1995 before dropping back to 14 TBq (380 Ci) in 2004. Early Namurian basinal mudstones are the source rocks for these hydrocarbons. However, many animals of the seabed, the open sea and the seashore spend their juvenile stages as part of the zooplankton. ADMIRALTY Chart - 1123 Western Approaches to Saint George's Channel and Bristol Channel. The gas is then sent by onshore pipeline to PowerGen's combined cycle gas turbine power station at Connah's Quay. [31] Improvements in the treatment of waste in 1985 and 1994 resulted in further reductions in radioactive waste discharge although the subsequent processing of a backlog resulted in increased discharges of certain types of radioactive waste. The site currently has seven GE 3.6 MW turbines, each with 104-metre (341 ft) diameter rotors, the world's first commercial application of offshore wind turbines over three megawatts in size. [25], Twenty-one species of seabird are reported as regularly nesting on beaches or cliffs around the Irish Sea. The term Manx Sea may occasionally be used. At the height of the glaciation, the central part of the modern sea was probably a long freshwater lake. The common or harbour seal and the grey seal are both resident in the Irish Sea. Whales, dolphins and porpoises all frequent the Irish Sea, but knowledge of how many there may be and where they go is somewhat sketchy. The Liverpool Bay Development is BHP Billiton Petroleum's largest operated asset. Folio 3 Irish Sea, F. of Clyde, North of Ireland. Despite the Tertiary structuration, the Dragon discovery has proved that potentially commercial volumes of hydrocarbons were retained at least locally in Cardigan Bay. Ring in the new year with a Britannica Membership. Its greatest depth measures about 576 feet (175 m) at the Mull of Galloway, near the sea’s junction with the North Channel. By Tom de Castella BBC News Magazine. The Norman invasion of Ireland took place in stages during the late 12th century from Porthclais near St. Davids, Wales, in Hulks, Snekkars, Keels and Cogs[11] to Wexford Harbour, Leinster. £23.95. The Irish Sea, at its greatest width, is 120 miles (190 km) and narrows to 47 miles (76 km).[9]. add. Wells in the Irish Sector to the west have demonstrated that pre-rift, Westphalian coal measures are excellent hydrocarbon source rocks, and are at peak maturity for gas generation (Maddox et al., 1995). The sea is connected with the Atlantic by the North Channel between Northern Ireland and Scotland and by St. George’s Channel between the southeastern tip of Ireland and southwestern Wales. [40] In terms of risk to this group, heavy consumption of seafood generates a 1 in 18 million chance of causing cancer. These build up large structures over many years and, in turn, provide surfaces, nooks and crannies where other marine animals and plants may become established and live out some or all of their lives. An offshore wind farm was developed on the Arklow Bank,[50] Arklow Bank Wind Park, about 10 km (6.2 mi) off the coast of County Wicklow in the south Irish Sea. Written Answers. Anglesey and Holy Island are included separately. analysis of vintage 2-D seismic data has revealed the presence of a large undrilled structural closure at Lower Triassic level situated about 10 kilometres (6 mi) offshore Dublin. [39] This compares with a corresponding dosage of radioactivity naturally occurring in the seafood consumed by this group of 148 Î¼Sv (0.0148 rem) and a total average dosage in Ireland from all sources of 3,620 Î¼Sv (0.362 rem). Folio 5 West Coast of Scotland. local_library. [10] Notable crossings include several invasions from Britain. This feature, known as the Dalkey Island exploration prospect, may be prospective for oil, as there are prolific oil productive Lower Triassic reservoirs nearby in the eastern Irish Sea offshore Liverpool. Close Upload Layer file_upload Print Map print Bookmarks bookmark. Having the border in the Irish sea is where it belongs. The purpose of the Irish Sea Pilot was to help develop a strategy for marine nature conservation that could be applied to all UK waters and, with international collaboration, the adjacent waters of the north-east Atlantic. The general risk of contracting cancer in Ireland is 1 in 522. Others depend on the milder climate as a refuge when continental Europe is in the grip of winter. After initial processing at the Douglas Complex the gas is piped by subsea pipeline to the Point of Ayr gas terminal for further processing. Folio4 West Coast of Ireland. At 50 miles (80 km), it would have been by far the longest rail tunnel on earth with an estimated cost approaching £20 billion.[49]. The Cardigan Bay Basin contains multiple reservoir targets, which include the Lower Triassic (Sherwood Sandstone), Middle Jurassic shallow marine sandstones and limestone (Great Oolite), and Upper Jurassic fluvial sandstone, the reservoir for the Dragon discovery. Several potential projects have been proposed, including one between Dublin and Holyhead put forward in 1997 by the British engineering firm Symonds. £23.95. Brown shrimp, cockles and edible mussels support local fisheries in Morecambe Bay and the Dee Estuary and the estuaries are also important as nurseries for flatfish, herring and sea bass. Northern Ireland ports handle 10 million tonnes (9,800,000 long tons; 11,000,000 short tons) of goods trade with the rest of the United Kingdom annually; the ports in the Republic of Ireland handle 7.6 million tonnes (7,500,000 long tons; 8,400,000 short tons), representing 50% and 40% respectively of total trade by weight. Some of the most significant for other wildlife are the reef-building species like the inshore horse mussel of Strangford Lough and the inter-tidal honeycomb worm of Morecambe Bay, Cumbria and Lancashire. Traditionally, many Irish shippers ship LTL trailers across the Irish Sea with goods for Great Britain and the Continent. 200-300m, which is considerably more.

The Irish Sea (Irish: Muir Éireann / An Mhuir Mheann,[1] Manx: Y Keayn Yernagh,[2] Scots: Erse Sie Scottish Gaelic: Muir Èireann,[3] Ulster-Scots: Airish Sea, Welsh: Môr Iwerddon, Cornish: Mor Iwerdhon) separates the islands of Ireland and Great Britain; linked to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland[4] in the north by the North Channel, also known as the Straits of Moyle. Sea Fishing Maps for Ireland. [25] In 2005, a plan to reintroduce grey whales by airlifting 50 of them from the Pacific Ocean to the Irish Sea was claimed to be logically and ethically feasible;[28] it had not been implemented by 2013. Dunlop proposes a cable-stayed or suspension bridge for the shallower sections and a floating pontoon-style bridge (“tied to the sea bed with cables like an oil rig”) for the deeper sections. The forum followed the completion of in-depth supply chain scoping exercises undertaken by EI’s cluster leaders, Darragh Cotter and Liam Curran, in which more than 80 Irish companies with the potential to supply the offshore wind industry were identified. "Irish Sea" is also the name of one of the BBC's Shipping Forecast areas defined by the coordinates: Transport for Wales Rail, Iarnród Éireann, Irish Ferries, Stena Line, Northern Ireland Railways, Stena Line and Abellio ScotRail promote SailRail with through rail tickets for the train and the ferry.[16]. 1996. Currents are weakest in the west-central Irish Sea. On the west, Dublin, with extensive quays on the River Liffey, handles much of the cargo trade of the Republic of Ireland. [41] This compares to average annual dose of naturally sourced radiation received in the UK of 2,230 Î¼Sv (0.223 rem). A bridge across the Irish Sea and four other amazing plans. Less soluble elements such as plutonium are subject to much slower redistribution. Folio 5 West Coast of Scotland. As an example of this profile, discharges of plutonium (specifically 241Pu) peaked in 1973 at 2,755 terabecquerels (74,500 Ci)[30] falling to 8.1 TBq (220 Ci) by 2004. Sellafield nuclear reprocessing facility. We calculate distances between ports and ports or ports and vessels Distance calculator for maritime industry online, worldwide and free of charge Weather; Sea Marks; Harbours; Tidal Scale; Sport Population figures are from 2001 Census, except: Isle of Man, from 2006. The more rarely seen species are minke whale, fin whale, sei whale, humpback whale, North Atlantic right whales[27] which are now considered to be almost extinct in eastern North Atlantic, sperm whale, northern bottlenose whale, long-finned pilot whale, orca, white-beaked dolphin, striped dolphin and Risso's dolphin. With a total water volume of 2,430 km3 (580 cu mi) and a surface area of 47,000 km2 (18,000 sq mi), 80% is to the west of the Isle of Man. The Irish Sea is the world's most heavily nuclear contaminated sea. The Irish Sea was formed in the Neogene era. close. This leads to differing populations of plankton in different parts of the sea and varying communities of animals that feed on these populations. For example, where freshwater flows into the Irish Sea in river estuaries its influence can extend far offshore as the freshwater is lighter and "floats" on top of the much larger body of saltwater until wind and temperature changes mix it in. Similarly, warmer water is less dense and seawater warmed in the inter-tidal zone may "float" on the colder offshore water. Production from all fields is from fault-bounded traps of the Lower Triassic formation, principally the aeolian Sherwood Sandstone reservoir, top-sealed by younger Triassic continental mudstones and evaporites.

The Irish Sea, also known as the Mann Sea, Manx Sea and Celtic Sea, separates the islands of Ireland and Great Britain. (Irish: Muir Meann[5] Manx: Mooir Vannin, Scottish Gaelic: Muir Mhanainn).[6][7][8]. According to a study in 2014, the economic value of the Irish Sea is around £6 billion per year. [36] The highest concentration is found in the eastern Irish Sea in sediment banks lying parallel to the Cumbrian coast. To the north, the connection is through the North Channel between Scotland and Northern Ireland and the Malin Sea. However, a lot of wildlife also depends on the cliffs, salt marshes and sand dunes of the adjoining shores, the seabed and the open sea itself. Visualising Marine Landscapes.

The operating company, Airtricity, has indefinite plans for nearly 100 further turbines on the site. AC1121. With United Kingdom / Ireland Marine Chart App you get access to beautiful vector and raster charts in following United Kingdom / Ireland regions. [45][46][47][48] The idea for a 21-mile (34 km) long rail bridge or tunnel continues to be mooted. Annual traffic between Great Britain and Ireland amounts to over 12 million passengers and 17 million tonnes (17,000,000 long tons; 19,000,000 short tons) of traded goods. The Irish Sea joins the North Atlantic at both its northern and southern ends. The basin has a proven petroleum system, with potentially producible gas reserves at the Dragon discovery near the UK/ROI median line, and oil shows in a further three wells. This article was most recently revised and updated by, https://www.britannica.com/place/Irish-Sea. The Irish Sea is located Great Britain and Ireland.

Find out how deep your knowledge of oceans and seas goes with this quiz. There are quite regular records of live and stranded leatherback turtle in and around the Irish Sea. Herring and whiting are fished, and there is some trawling for cod and flatfish. The Irish Sea joins the North Atlantic at both its northern and southern ends. The seabed under the Celtic Sea is referred to as the Celtic Shelf, part of the continental shelf of Europe. Name: Irish Sea topographic map, elevation, relief.. Coordinates: 51.37693 -6.64398 55.29212 -3.06381. The Cardigan Bay Basin forms a continuation into British waters of Ireland's North Celtic Sea Basin, which has two producing gas fields. Radioactivity in Food and the Environment 2005. In classical times the Irish Sea was known as Oceanus Hibernicus. add. Map with JOSM Remote; View. As in the East Irish Sea Basin, the principal target reservoir is the Lower Triassic, Sherwood Sandstone, top-sealed by younger Triassic mudstones and evaporites. [11] In 1690 the English fleet set sail for the Williamite War in Ireland from Hoylake, Wirral, the departure becoming permanently known as King's Gap as a result. The Real Map of Ireland shows Ireland's current designated Irish Continental Shelf, which is one of the largest seabed territories in Europe. The International Hydrographic Organization defines the limits of the Irish Sea (with St George's Channel) as follows. Dun Laoghaire, Howth, Skerries, and Mornington—all near Dublin—are important fishing ports for the Republic of Ireland. Studies have revealed that 80% of current sea water contamination by caesium is sourced from sediment banks, whilst plutonium levels in the western sediment banks between the Isle of Man and the Irish coast are being maintained by contamination redistributed from the eastern sediment banks. The sea is about 130 miles (210 km) long and 150 miles (240 km) wide. Assessing Impact in Irish Sea. Its total area is approximately 40,000 square miles (100,000 square km). Surface tidal currents reach a speed of more than 4 knots in St. George’s Channel, near the Irish coast, and are locally strong elsewhere. A colossal diversity of invertebrate species live in the Irish Sea and its surrounding coastline, ranging from flower-like fan-worms to predatory swimming crabs to large chameleon-like cuttlefish. The Irish Sea is an important transportation route between Britain and Ireland. While every effort has been made to follow citation style rules, there may be some discrepancies. Muddy seabeds in deeper waters are home to populations of the Dublin Bay prawn, also known as "scampi".[25]. Isle of Man. Most are microscopic, but some, such as the various species of jellyfish and sea gooseberry, can be much bigger. As the ice retreated 10,000 years ago, the lake reconnected to the sea. Loggerhead turtle, ridley sea turtle and green turtle are found very occasionally in the Irish Sea but are generally unwell or dead when discovered. Parts of the bed of the Irish Sea are very rich in wildlife. Measurements of technetium concentrations post-1994 has produced estimated transit times to the North Channel of around six months with peak concentrations off the northeast Irish coast occurring 18–24 months after peak discharge. The Liverpool Bay development comprises four offshore platforms. Calls to create ‘capital cities axis’ driven by Irish Sea tunnel 06 Jan, 2021 By Catherine Kennedy Transport thinktank Greengauge 21 has called for the creation of a Scotland-Northern Ireland tunnel which could form part of a ‘capital cities axis’ between Dublin, Belfast, Glasgow and Edinburgh. With 210 billion cubic metres (7.5 trillion cubic feet) of natural gas and 176 million barrels (28,000,000 m3) of petroleum estimated by the field operators as initially recoverable hydrocarbon reserves from eight producing fields (DTI, 2001), the East Irish Sea Basin is at a mature exploration phase. Cardigan Bay in the south, and the waters to the east of the Isle of Man, are less than 50 m (160 ft) deep. Doré and Jensen, 1996). Seismic profiles clearly image these strata continuing beneath a basal Permian unconformity into at least the western part of the Caernarfon Bay Basin. This is certainly “doable”, as the Seikan Tunnel between Honshu and Hokkaido in Japan is up to 240m below sea level at its lowest point. Share.

The world's largest car ferry, Ulysses, is operated by Irish Ferries on the Dublin Port–Holyhead route; Stena Line also operates between Britain and Ireland. Gas-prone, Westphalian pre-rift coal measures may also be present at depth locally. It can be traced back to a 26-year-old Scottish man performing a … Only two exploration wells have been drilled so far, and there remain numerous undrilled targets in tilted fault block plays. The open sea is a complex habitat in its own right. Corrections? Alternatively, the fault block traps could have been recharged by exsolution of methane from formation brines as a direct result of the Tertiary uplift (cf. Because of this commercial fishing is lower than it would be otherwise. The whole plankton "soup" is vitally important, directly or indirectly, as a food source for most species in the Irish Sea, even the largest. Maximum burial of, and primary gas migration from, the source rocks could have terminated as early as the Jurassic, whereas many of the tilted fault blocks were reactivated or created during Paleogene inversion of the basin. Geologic studies seem to indicate that the Irish Sea originated by rifting during the Paleogene and Neogene periods (about 65 to 2.6 million years ago), and subsidence of its basins was probably initiated or renewed at that time. More challenging than the length of such a bridge is the depth of the sea bed – up to 160 metres at its deepest section. The Isle of Man lies in the centre of the northern part, and Anglesey lies close to the coast of North Wales. Scallops and queen scallops are found in more gravelly areas. [32] Current rates of discharge for many radionuclides are at least 100 times lower than they were in the 1970s.[33]. Whilst the Dalkey Island exploration prospect could contain about 870 million barrels (140,000,000 m3) of oil in place, this undrilled prospect still has significant risk and the partners are currently advancing a focused work programme in order to better understand and hopefully mitigate these risks. The seabed southwest of the Isle of Man is particularly noted for its rarities and diversity,[24] as are the horse mussel beds of Strangford Lough. These are fully mature for oil generation in the west of the British sector, and are mature for gas generation nearby in the Irish sector. The largest sandbanks are the Bahama and King William Banks to the east and north of the Isle of Man and the Kish Bank, Codling Bank, Arklow Bank and Blackwater Bank near the coast of Ireland. However, increasing seasonal storminess leads to greater mixing of water and tends to break down these divisions, which are more apparent when the weather is calm for long periods. Omissions? It's connected to the Atlantic Ocean through St. George's Channel and the Celtic Sea, and by the North Channel between Northern Ireland and Scotland. Politics. difficult for bridges than the 30-50m depth of the English Channel, for instance. 1) Definition of region.

It covers 45,000km and is 300m deep at its deepest point. we should build giant sea barriers shown in red on this map then pump out the irish sea and claim the land and fill it up with construction and demolition waste and sand (to bulk up most of that 300metres depth) then cover it over with plenty of imported top soil. £23.95. [37] The environmental monitoring report for the period 2003 to 2005 published by the Radiological Protection Institute of Ireland (RPII) reported that in 2005 average quantities of radioactive contamination found in seafood ranged from less than 1 Bq/kg (12 pCi/lb) for fish to under 44 Bq/kg (540 pCi/lb) for mussels. On its shoreline are Scotland to the north, England to the east, Wales to the southeast, Northern Ireland and the Republic of Ireland to the west. It is also connected to the Inner Seas off the West Coast of Scotland via the North Channel. From Scotland, Cairnryan connects with both Belfast and Larne. Whilst concentrations have declined in line with the reduction in discharges they are markedly higher in the eastern Irish Sea compared to the western areas. Ferry connections from Wales to Ireland across the Irish Sea include Fishguard Harbour and Pembroke to Rosslare, Holyhead to Dún Laoghaire and Holyhead to Dublin. The introduction of customs and regulatory controls in the Irish Sea, provided for in the latest UK withdrawal agreement, would make Northern Ireland a very special economic area.
