The Holocene is the current geological epoch. It began approximately 11,700 years before 2000 CE. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.
Water is an inorganic compound with the chemical formula H2O. It is a transparent, tasteless, odorless, and nearly colorless chemical substance, and it is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, despite not providing food energy, or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure.
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of 637,000 square kilometres (246,000 sq mi).
Krill are small crustaceans of the order Euphausiacea, found in all the world's oceans. The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", which is also often attributed to species of fish.
Louis Eugène Félix Néel was a French physicist born in Lyon who received the Nobel Prize for Physics in 1970 for his studies of the magnetic properties of solids.
The International Council for the Exploration of the Sea is a regional fishery advisory body and the world's oldest intergovernmental science organization. ICES is headquartered in Copenhagen, Denmark, where its multinational secretariat staff of 51 provide scientific, administrative and secretarial support to the ICES community. It was established on July 22, 1902, in Copenhagen.
The Western Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains that lies in the Western Hemisphere. The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves. The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea.
The Greenland ice sheet is a vast body of ice covering 1,710,000 square kilometres (660,000 sq mi), roughly near 80% of the surface of Greenland. It is sometimes referred to as an ice cap, or under the term inland ice, or its Danish equivalent, indlandsis. The acronym GIS is frequently used in the scientific literature.
Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of fisheries. In some cases new disciplines have emerged, as in the case of bioeconomics and fisheries law. Because fisheries science is such an all-encompassing field, fisheries scientists often use methods from a broad array of academic disciplines. Over the most recent several decades, there have been declines in fish stocks (populations) in many regions along with increasing concern about the impact of intensive fishing on marine and freshwater biodiversity.
The American Political Science Review is a quarterly peer-reviewed academic journal covering all areas of political science. It is an official journal of the American Political Science Association and is published on their behalf by Cambridge University Press. The journal was established in 1906. It is considered a flagship journal in political science.
The Centre for Environment, Fisheries and Aquaculture Science (Cefas) is an executive agency of the United Kingdom government Department for Environment, Food and Rural Affairs (Defra). It carries out a wide range of research, advisory, consultancy, monitoring and training activities for a large number of customers around the world.
Nemadactylus macropterus, the tarakihi, jackass morwong or deep sea perch, is a species of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found in the south western Pacific Ocean, in Australia and New Zealand. Although there are records from the southern Indian Ocean and southwestern Atlantic, these may be due to misidentifications of similar species.
The American Sociological Review is a bi-monthly peer-reviewed academic journal covering all aspects of sociology. It is published by SAGE Publications on behalf of the American Sociological Association. It was established in 1936. The editors-in-chief are Arthur S. Alderson and Dina G. Okamoto.
Social Forces is a quarterly peer-reviewed academic journal of social science published by Oxford University Press for the Department of Sociology at the University of North Carolina at Chapel Hill. It concentrates on sociology but also has a multidisciplinary approach, publishing works from the fields of social psychology, anthropology, political science, history, and economics. Each issue includes between 20 and 25 articles. In addition, the journal also publishes book reviews.
Maerl is a collective name for non-geniculate coralline red algae with a certain growth habit. Maerl grows at a rate of c. 1 mm per year. It accumulates as unattached particles and forms extensive beds in suitable sublittoral sites. The term maerl originally refers to the branched growth form of Lemoine (1910) and rhodolith is a sedimentological or genetic term for both the nodular and branched growth forms.
Didier Raoult is a retired French physician and microbiologist specialising in infectious diseases. He taught about infectious diseases at the Faculty of Medicine of Aix-Marseille University (AMU), and in 1984, created the Rickettsia Unit of the university. From 2008 to 2022, Raoult was the director of the Unité de Recherche sur les Maladies Infectieuses et Tropicales Emergentes. He gained significant worldwide attention during the COVID-19 pandemic for vocally promoting hydroxychloroquine as a treatment for the disease, despite the lack of evidence for its effectiveness and the subsequent opposition from NIH and WHO to its use for the treatment of COVID-19 in hospitalized patients.
Edward Stuart Russell OBE FLS was a Scottish biologist and philosopher of biology.
Raymond (Ray) John Heaphy Beverton CBE FRS was an important founder of fisheries science. He is best known for the book On the Dynamics of Exploited Fish Populations (1957) which he wrote with Sidney Holt. The book is a cornerstone of modern fisheries science and remains much used today. Beverton's life and achievements are described in detail in several obituaries written by prominent figures in fisheries science.
Among the effects of climate change on oceans are an increase of ocean temperatures, more frequent marine heatwaves, ocean acidification, a rise in sea levels, sea ice decline, increased ocean stratification, reductions in oxygen levels, changes to ocean currents including a weakening of the Atlantic meridional overturning circulation. All these changes have knock-on effects which disturb marine ecosystems. The primary factor causing these changes is climate change due to human-caused emissions of greenhouse gases, such as carbon dioxide and methane. This leads inevitably to ocean warming, because the ocean is taking up most of the additional heat in the climate system. The ocean absorbs some of the extra carbon dioxide in the atmosphere and this causes the pH value of the ocean to drop. It is estimated that the ocean absorbs about 25% of all human-caused CO2 emissions.
