Bursatella Leachii
''Bursatella leachii'', whose common name is the ragged sea hare or shaggy sea hare, is a species of large sea slug: a marine (ocean), marine gastropod mollusk in the sea hare family Aplysiidae.MolluscaBase eds. (2021). MolluscaBase''Bursatella leachii'' Blainville, 1817.Accessed through: World Register of Marine Species on 2021-01-27. It has an almost pantropical distribution, from the Mediterranean Sea, Mediterranean to the Caribbean, but excluding the central and eastern Pacific Ocean. Its long Plankton, planktonic larval period and short life cycle make able to colonise new areas and increase dramatically in number if food supplies are favourable.

Auckland Museum
The Auckland War Memorial Museum (), also known as Auckland Museum, is one of New Zealand's most important museums and war memorials. Its neoclassical architecture, neoclassical building constructed in the 1920s and 1950s, stands on Observatory Hill, the remains of a dormant volcano, in the Auckland Domain, near Auckland CBD. Museum collections concentrate on New Zealand history (and especially the history of the Auckland Region), natural history, and military history. Auckland Museum's collections and exhibits began in 1852. In 1867 Aucklanders formed a learned society—the Auckland Philosophical Society, soon renamed Auckland Institute. Within a few years Auckland Museum was transferred to Auckland Institute, thereafter known as Auckland Institute and Museum until 1996. Auckland War Memorial Museum was the name of the new building opened in 1929, but since 1996 it has been more commonly used for the institution as well. From 1991 to 2003 the Museum's Māori-language, Māori n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, Deforestation and climate change, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices release greenhouse gases. These gases greenhouse effect, absorb some of the heat that the Earth Thermal radiation, radiates after it warms from sunlight, warming the lower atmosphere.

Strait Of Gibraltar
The Strait of Gibraltar is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Europe from Africa. The two continents are separated by 7.7 nautical miles (14.2 kilometers, 8.9 miles) at its narrowest point. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between . The strait lies in the territorial waters of Morocco, Spain, and the British overseas territory of Gibraltar. Under the United Nations Convention on the Law of the Sea, foreign vessels and aircraft have the freedom of navigation and overflight to cross the strait of Gibraltar transit passage, in case of continuous transit. Names and etymology The name comes from the Rock of Gibraltar, which in turn originates from the Arabic (meaning "Tariq's Mount"), named after Tariq ibn Ziyad. It is also known as the Straits of Gibraltar, the Gut (coastal geography), Gut of Gibraltar (although this is mostly archaic), the STROG (STRait Of ...

Sea Surface Temperature
Sea surface temperature (or ocean surface temperature) is the ocean temperature, temperature of ocean water close to the surface. The exact meaning of ''surface'' varies in the literature and in practice. It is usually between and below the sea surface. Sea surface temperatures greatly modify air masses in the Atmosphere of Earth, Earth's atmosphere within a short distance of the shore. The thermohaline circulation has a major impact on average sea surface temperature throughout most of the world's oceans. Warm sea surface temperatures can develop and Tropical cyclogenesis, strengthen cyclones over the ocean. Tropical cyclones can also cause a cool wake. This is due to turbulent mixing of the upper of the ocean. Sea surface temperature changes during the day. This is like the air above it, but to a lesser degree. There is less variation in sea surface temperature on breezy days than on calm days. Coastal sea surface temperatures can cause offshore winds to generate upwelling ...

Ballast Water Discharge And The Environment
Ballast water discharges by ships can have a negative impact on the marine environment. The discharge of ballast water and sediments by ships is governed globally under the Ballast Water Management Convention, since its entry into force in September 2017. It is also controlled through national regulations, which may be separate from the Convention, such as in the United States. Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever more cargo is loaded. Ballast water discharge typically contains a variety of biological materials, including plants, animals, viruses, and bacteria. These materials often include non-native, nuisance, and exotic species that can cause extensive ecological and economic damage to aquatic ecosystems, along with serious human health issues including death.

Suez Canal
The Suez Canal (; , ') is an artificial sea-level waterway in Egypt, Indo-Mediterranean, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia (and by extension, the Sinai Peninsula from the rest of Egypt). The canal is a key trade route between Europe and Asia. In 1858, French diplomat Ferdinand de Lesseps formed the Suez Canal Company, Compagnie de Suez for the express purpose of building the canal. Construction of the canal lasted from 1859 to 1869. The canal officially opened on 17 November 1869. It offers vessels a direct route between the Atlantic Ocean#North Atlantic, North Atlantic and northern Indian Ocean, Indian oceans via the Mediterranean Sea and the Red Sea, avoiding the South Atlantic and southern Indian oceans and reducing the journey distance from the Arabian Sea to London by approximately , to 10 days at or 8 days at . The canal extends from the northern terminus of Port Said to the southern terminus of Port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Sea
The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly , is about long, and wide at its widest point. It has an average depth of , and in the central Suakin Trough, it reaches its maximum depth of . Approximately 40% of the Red Sea is quite shallow at less than deep and about 25% is less than deep. The extensive shallow shelves are noted for their marine life and corals. More than 1,000 invertebrate species and 200 types of soft and hard coral live in the sea. The Red Sea is the world's northernmost tropical sea and has been designated a Global 200 ecoregion.

Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. As a distinct marine realm, the region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in all directions. The region includes over 3,000 species of fish, compared with around 1,200 in the next richest marine region, the Western Atlantic, and around 500 species of reef building corals, compar ...
