Celtic Sea: general information
The Celtic Sea is the sea of the Atlantic Ocean basin. Washes part of Ireland, Great Britain and France. The sea borders are limited by the St George Strait, the Bristol Bay, the English Channel. The southern and western boundaries are delineated along the continental shelf.
The waters of the Celtic Sea are one of the richest areas of marine life and were designated by UNESCO as a «Biosphere Reserve» in 1988.
The climate of the reservoir will be equal to the temperate oceanic one. The water temperature in this area is noticeably lower than in the Adriatic Sea. Temperature conditions may vary depending on the season. In deeper layers, it varies from + 9 ° C to + 12 ° C. As for the salinity of water, it is at a more stable level - 35.7-36 ‰.
The main advantage of the reservoir is its favorable location in a kind of «wind rose», which is a constant source of a fairly strong wind. Due to this feature, local residents widely use wind generators in their activities.
In the summer season, the temperature profile of the waters is clearer and more vertical. Storms are frequent during the winter months, which also have a vertically mixed thermal environment. Studies show that the latter has become less constant due to global mixing that occurred about 6200 years ago.
