Both islands are separated from the Davis Coast to the south by Orléans Strait, running northeast–southwest. The Pearl Rocks lie off the West Coast of Tower Island. The island was named on 30 January 1820 by Edward Bransfield, Master, Royal Navy, who described it as a round island. Named features A number of features on Tower Island have been charted and named by various Antarctic expeditions. The following description of features begins from the north and proceeds clockwise along the coast to the east. East coast The northernmost point of the island is called Cape Leguillou. It was charted by a French expedition under Captain Jules Dumont d'Urville, 1837–40, and named by him after Élie Le Guillou, a surgeon on the expedition corvette .

Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost .

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...

Kendall Rocks
The Kendall Rocks () are a group of pillar-shaped rocks, lying north of Tower Island in the Palmer Archipelago, Antarctica. The name "Kendall Group" appears northwest of this position on a chart based upon work by a British expedition under Commander Henry Foster (scientist), Henry Foster, Royal Navy, 1828–31, but it was later found that no islands exist there. The name Kendall Rocks has subsequently been applied to these pillar-shaped rocks discovered in 1838 by a French expedition under Captain Jules Dumont d'Urville. They are named for Lieutenant E.N. Kendall of Foster's expedition ship, the ''HMS Chanticleer (1808), Chanticleer''. References Rock formations of the Palmer Archipelago {{PalmerArchipelago-geo-stub ...

Kranevo
Kranevo ( bg, Кранево) is a coastal village on the northern Bulgarian Black Sea Coast, part of Balchik Municipality, Dobrich Province. It is located in the historical region of Southern Dobruja. Between 1913 and 1940 it was part of Romania, being its southernmost settlement. An important lighthouse is installed on ''Cape Ekrene'', 3 km (2 mi) south of the village. Kranevo enjoys high tourist population during summers and two of the reasons are its proximity to Albena (less than half an hour on foot, by walking on the beach) and its clearly lower prices. History The settlement was founded in the Ancient period, probably by the ancient Thracians and in the next periods was part of the Roman, Bulgarian and Ottoman Empires. Its name during Ottoman rule was ''Ekrene'', and ''Ecrene'' under Romanian administration. Due to the constant landslide activity in the area, the activity of the lighthouse was stopped. Not far from it are the remains of the defensive shaft, which p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple Function (biology), functions. Bone tissue (osseous tissue), which is also called bone in the mass noun, uncountable sense of that word, is hard tissue, a type of specialized connective tissue. It has a honeycomb-like matrix (biology), matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralization (biology), mineralization of bone; osteoclasts are involved in the bone resorption, resor ...
