Cardigan Bay (Welsh : Bae Ceredigion) is a large inlet of the Irish Sea, indenting the west coast of Wales between Bardsey Island, Gwynedd in the north, and Strumble Head, Pembrokeshire at its southern end. It is the largest bay in Wales. [1]

Geography

Cardigan Bay has numerous beaches, and marine life. Much of the coast surrounding the bay is fertile farmland, dotted with towns and seaside resorts such as Fishguard, New Quay, Aberaeron, Llanon, Aberystwyth, Borth, Aberdyfi, Tywyn, Barmouth, Porthmadog, Criccieth and Pwllheli on the Cambrian Coast. Smaller coastal villages include Cwmtydu, Nanternis and Llangrannog.

Major rivers flowing into the bay include the Glaslyn, Mawddach, Dysynni, Dyfi, Rheidol, Ystwyth, Aeron and Teifi.

History

Until the early 20th century, Cardigan Bay supported a strong maritime industry. Cardigan is located at the mouth of the River Teifi; hence the Welsh name, Aberteifi (Mouth of the Teifi). At the turn of the 19th century, the heyday of the port, it was a more important port than Cardiff. At this time more than 300 ships were registered at Cardigan—seven times as many as Cardiff, and three times as many as Swansea. [2]

The central and northern areas of the bay are the location of the legendary Cantre'r Gwaelod, the drowned "Lowland Hundred" or "Hundred under the Sea". During the winter storms of 2014, parts of the lost ancient forest of Borth, which 4,500 years ago stretched on the boggy land to Ynyslas, reappeared on the shoreline in the form of preserved exposed tree stumps. Due to climate change and rising sea levels, the forest was buried under layers of peat, sand and saltwater. [3]

Nature and tourism

The Cardigan Bay Special Area of Conservation was set up to preserve the natural wildlife in the area, both in the sea and on the surrounding foreshore.

From the Ceredigion Coast Path it is often possible to observe the Bay's "Big Three" species of harbour porpoise, grey seals, [4] and bottlenose dolphins, of which the bay has the largest population in the UK. [5] Other mammals, such as minke whales, Risso's dolphins and common dolphins, together with many species of seabirds, such as puffin, and sharks, including basking sharks, can also be seen.

Since the late 1990s and early 2000s, the bay has been invaded by spider crabs. [6] Not a seafood normally consumed by British people, since 2010 the local fishermen have supplied the Michelin-starred restaurants of Raymond Blanc. [7]

Military testing

A military testing range was first established in Cardigan Bay during the Second World War. The range is controlled from a main operating base located near Aberporth, known as MoD Aberporth. Historically, the range has played a significant part in the development and testing of a variety of military weapons. [8]

Today the Ministry of Defence (MOD) range within Cardigan Bay provides a large secure safety area for the testing of air launched weapons and unmanned aerial systems. The range is a significant employer in the West Wales area, employing some 200 people who work in direct support of the range operation.

The Range Danger Area covers some 6,500 km2 (2,500 sq mi) of Cardigan Bay from sea level to unlimited height. To supplement the safe operation of the range, there are a number of small outposts located on the edge of Cardigan Bay and the Llŷn Peninsula. These outposts contain equipment that enables the range to effectively assess the performance of weapons. [8]

Qinetiq operates the Cardigan Bay/Aberporth Range on behalf of the MOD under the terms of a Long Term Partnering Agreement. The purpose of the agreement is to deliver defence test, evaluation and training support services to ensure air launched weapon systems, associated sub-systems and UAS are safe and fit for purpose.

Sarn Gynfelyn is a shingle spit on the coast of Cardigan Bay, in the county of Ceredigion, Mid-Wales, in the United Kingdom. It is located at Wallog, a few kilometres north of Llangorwen, close to Clarach Bay, south of Borth and north of the town of Aberystwyth. It extends, albeit with a single break, for a distance of 11km from the coast to a reef known as Patches or Caerwyddno.

The Ceibwr Bay Fault is a WSW-ENE trending fault zone that cuts Ordovician rocks of the Ashgill Nantmel Mudstones Formation and the Caradoc Dinas Island Formation. The fault is exposed on the south side of Cardigan Bay in Wales and forms part of the Fishguard-Cardigan Fault Zone. It extends from the coast at Ceibwr Bay at its western end to the coast at Aberporth at its eastern end. The fault zone is thought to have been active as a normal fault throughout the deposition of the Ordovician sequence.

<span class="mw-page-title-main">Ceibwr Bay</span>

Ceibwr Bay is a bay opening into the Irish Sea in Pembrokeshire, west Wales. It is about 7 km west of Cardigan, and 3 km south of the headland of Cemaes Head. It is owned by the National Trust, and lies within the Pembrokeshire Coast National Park and on the Pembrokeshire Coast Path.

The coast of Ceredigion is made up of a long coastal plain that contains high cliffs, coves, large bays and estuaries. The coastal plain gets narrower towards the more mountainous north of the county and is cut by the wide estuaries of the Teifi and the Dyfi. The broad and fertile Teifi valley is ideal for dairy farming and mixed farming. Heavy rainfall washes the minerals out of the soil and results in the mountainous areas of the county having relatively poorer, acidic soils. The plough line can be as low as 700 feet, which restricts cultivation.

The bedrock geology of Ceredigion in west Wales consists wholly of a considerable thickness of Ordovician and Silurian age sedimentary rocks of marine origin. Unconsolidated deposits of Quaternary age include a widespread cover of glacial till, valley floor alluvium and scattered peat deposits in both upland and lowland settings.

<span class="mw-page-title-main">Coastline of Wales</span> Sea-bounded areas of Wales

The coastline of Wales extends from the English border at Chepstow westwards to Pembrokeshire then north to Anglesey and back eastwards to the English border once again near Flint. Its character is determined by multiple factors, including the local geology and geological processes active during and subsequent to the last ice age, its relative exposure to or shelter from waves, tidal variation and the history of human settlement and development which varies considerably from one place to another. The majority of the coast east of Cardiff in the south, and of Llandudno in the north, is flat whilst that to the west is more typically backed by cliffs. The cliffs are a mix of sandstones, shales and limestones, the erosion of which provides material for beach deposits. Of the twenty-two principal areas which deliver local government in Wales, sixteen have a coastline, though that of Powys consists only of a short section of tidal river some distance from the open sea. Its length has been estimated at 1,680 miles (2,700 km).
