Gills Bay
Gills Bay, which is situated about west of John o' Groats with the community of Gills close by, has one of the longest stretches of low-lying rock coast on the northern shores of Caithness. Its main features are a small harbour and the pier used as the mainland terminal for Pentland Ferries. The harbour shelters some small local boats together with those used for working the sheep on the off lying island of Stroma. In the right sea conditions the area is sometimes used for surfing. Short sea crossing While Scrabster to Stromness is the longest continuously used ferry route to Orkney, started in 1856, historically the Gills Bay area has been the main setting off point from the mainland to the islands of Stroma and Swona and Orkney itself. This route, known as The Short Sea Crossing, is generally considered to be both the quickest and safest across the waters of the Pentland Firth. At present Pentland Ferries operate a year-round service on this route to St Margaret's Hope on S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Ronaldsay
South Ronaldsay (, also , sco, Sooth Ronalshee) is one of the Orkney Islands off the north coast of Scotland. It is linked to the Orkney Mainland by the Churchill Barriers, running via Burray, Glimps Holm and Lamb Holm. Name Along with North Ronaldsay, the island is named after St Ronald. The original name from which the English name derives, ''Rǫgnvaldsey'', comes from Old Norse; ''Rǫgnvalds'' ("Ronald's") + ''ey'' ("island"). Geography and geology With an area of , it is the fourth largest of the Orkney islands after The Mainland, Hoy and Sanday. Ferries sail from Burwick on the island to John o' Groats on the Scottish mainland and from St Margaret's Hope to Gills Bay.Wenham, Sheena "The South Isles" in Omand (2003) p. 212. South Ronaldsay's main village is St Margaret's Hope, Orkney's third largest settlement. It is named either after Margaret, Maid of Norway, the heir to the Scottish throne who died in Orkney age sevenWenham, Sheena "The South Isles" in Omand (200 ...

Porpoises
Porpoises are a group of fully aquatic marine mammals, all of which are classified under the family Phocoenidae, parvorder Odontoceti (toothed whales). Although similar in appearance to dolphins, they are more closely related to narwhals and belugas than to the true dolphins. There are eight extant species of porpoise, all among the smallest of the toothed whales. Porpoises are distinguished from dolphins by their flattened, spade-shaped teeth distinct from the conical teeth of dolphins, and lack of a pronounced beak, although some dolphins (e.g. Hector's dolphin) also lack a pronounced beak. Porpoises, and other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Porpoises range in size from the vaquita, at in length and in weight, to the Dall's porpoise, at and . Several species exhibit sexual dimorphism in that the females are larger than males. They have streamlined bodies and two limbs that are modified into flippers. Porpoises use echolocatio ...

Common Seal
The harbor (or harbour) seal (''Phoca vitulina''), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinnipeds, pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic Ocean, Atlantic, Pacific Oceans, Baltic Sea, Baltic and North Seas. Harbor seals are brown, silvery white, tan, or gray, with distinctive V-shaped nostrils. An adult can attain a length of 1.85 m (6.1 ft) and a mass of up to . Blubber under the seal's skin helps to maintain body temperature. Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging area. Males may fight over mates under water and on land. Females bear a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Seal
The grey seal (''Halichoerus grypus'') is found on both shores of the North Atlantic Ocean. In Latin Halichoerus grypus means "hook-nosed sea pig". It is a large seal of the family Phocidae, which are commonly referred to as "true seals" or "earless seals". It is the only species classified in the genus ''Halichoerus''. Its name is spelled gray seal in the US; it is also known as Atlantic seal and the horsehead seal. Taxonomy There are two recognized subspecies of this seal: The type specimen of ''H. g. grypus'' (Zoological Museum of Copenhagen specimen ZMUC M11-1525, caught off the island of Amager, Danish part of the Baltic Sea) was believed lost for many years but was rediscovered in 2016, and a DNA test showed it belonged to a Baltic Sea specimen rather than from Greenland, as had previously been assumed (because it was first described in Otto Fabricius' book on the animals in Greenland: ''Fauna Groenlandica''). The name ''H. g. grypus'' was therefore transferred to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gills Bay Pier 2016
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill chambe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapa Flow
Scapa Flow viewed from its eastern end in June 2009 Scapa Flow (; ) is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray,S. C. George, ''Jutland to Junkyard'', 1973. South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World Wars, but the facility was closed in 1956. Scapa Flow has a shallow sandy bottom not deeper than and most of it is about deep; it is one of the great natural harbours and anchorages of the world, with sufficient space to hold a number of navies. The harbour has an area of and contains just under 1 billion cubic metres of water. Since the scuttling of the German fleet after World War I, its wrecks and their marine habitats form an internationally acclaimed diving lo ...

Lerwick
Lerwick (; non, Leirvik; nrn, Larvik) is the main town and port of the Shetland archipelago, Scotland. Shetland's only burgh, Lerwick had a population of about 7,000 residents in 2010. Centred off the north coast of the Scottish mainland and on the east coast of the Shetland Mainland, Lerwick lies north-by-northeast of Aberdeen; west of the similarly sheltered port of Bergen in Norway; and south east of Tórshavn in the Faroe Islands. One of the UK's coastal weather stations is situated there, with the local climate having small seasonal variation due to the maritime influence. Being located further north than Saint Petersburg and the three mainland Nordic capitals, Lerwick's nights in the middle of summer only get dark twilight and winters have below six hours of complete daylight. History Lerwick is a name with roots in Old Norse and its local descendant, Norn, which was spoken in Shetland until the mid-19th century. The name "Lerwick" means ''bay of clay''. The c ...

MV Pentalina-B
MV ''Pentalina-B'' was a ferry which operated on a variety of Scottish routes. Launched in 1970 as MV ''Iona'', she was the first drive-through roll-on/roll-off ferry built for the David MacBrayne fleet. She was the first ship in the company's history to have bridge-controlled engines and geared transmission, rather than direct drive. During her career she inaugurated more endloading linkspans than the rest of the fleet put together. Purchased by Pentland Ferries in 1997, she was renamed MV ''Pentalina-B'' and operated across the Pentland Firth until the arrival of their new vessel. In 2009, she was sold to a Cape Verde owner. History MV ''Iona'' (VII) was the first of a new generation of major car ferries built for the Scottish Transport Group to replace the ageing 1939 mailboat ''Lochiel'', serving Islay, Jura, Gigha and Colonsay from West Loch Tarbert. Early in 1968 MacBraynes were authorised to order a large new car ferry for the Argyll Hebrides and placed an order with the ...

Dolphin (structure)
A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids. Structure Dolphins typically consist of a number of piles driven into the seabed or riverbed, and connected above the water level to provide a platform or fixing point. The piles can be untreated or pressure treated timber piles, or steel or reinforced concrete piles. Smaller dolphins can have the piles drawn together with wire rope, but larger dolphins are typically fixed using a reinforced concrete capping or a structural steel frame. Access to a dolphin may be via a pedestrian bridge, particularly in the case of mooring dolphins, but is often by boat. Use As mooring point Dolphins are usually installed to provide a fixed structure when it would be impractical to extend the shore to provide a dry- ...

Linkspan
A linkspan or link-span is a type of drawbridge used mainly in the operation of moving vehicles on and off a roll-on/roll-off (RO-RO) vessel or ferry, particularly to allow for tidal changes in water level. Linkspans are usually found at ferry terminals where a vessel uses a combination of ramps either at the stern, bow or side to load or unload cars, vans, trucks and buses onto the shore, or alternately at the stern and/or the bow to load or unload railroad cars. History The first linkspans appeared at the end of the 19th century when train ferries came into operation. Each rail ferry berth has to be specifically designed to make sure that it fitted one class of ship. In most of these vessels it was also possible to carry some road vehicles. By the mid 20th century with the rise of road transport, general purpose Ro Ro ferries started to come into service. Most could use the rail ferry berths but generally they were fitted with stern ramps that had the dual function of gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Margaret's Hope
St Margaret's Hope is a village in the Orkney Islands, off the north coast of Scotland. It is known locally as "The Hope" or "The Hup". With a population of about 550, it is Orkney's third largest settlement after Kirkwall and Stromness. St Margaret's Hope is the main settlement of the island of South Ronaldsay. Situated off Water Sound at the head of a calm bay on the island's northern coast, it is connected to the Orkney Mainland by the A961 road running across the Churchill Barriers. St Margaret's Hope is believed to have been named after either Saint Margaret of Scotland (c.1045-1093), the wife of Malcolm III, or Margaret, Maid of Norway, who died in Orkney and possibly in this location in 1290. The village has a primary school, a small blacksmith's museum, a few shops and a cafe, a pub and a wine bar. Pentland Ferries run a reliable service from the pier in the bay to Gills Bay on the Scottish mainland. It is also known for its annual Boys' Ploughing Match A pl ...
