Sarah Fawcett
Sarah Fawcett is a South African oceanographer and climatologist. A senior lecturer in the Department of Oceanography at the University of Cape Town, she is particularly interested in the role of oceans in regulating biogeochemical cycles and how their dysregulation contributes to climate change. She was honoured in the World Economic Forum Young Scientists Class of 2020, and a P-Rating from the National Research Foundation, which recognizes that the scientist's work will likely have high impact. Early life Fawcett was born in Benoni, Gauteng, and attended Benoni High School. She went on to study Earth and planetary science at Harvard University (2006) and completed a PhD at Princeton (2012) where she later held a postdoctoral fellowship (2012-2015). Career In 2015, Fawcett was appointed a lecturer in oceanography at the University of Cape Town. She has worked to build up a diverse research group, aware of the discrimination still faced by female scientists. From 2016, she ha ...

Oceanography
Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology. History Early history Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations ...

Mail & Guardian
The ''Mail & Guardian'' is a South African weekly newspaper and website, published by M&G Media in Johannesburg, South Africa. It focuses on political analysis, investigative reporting, Southern African news, local arts, music and popular culture. It is considered a newspaper of record for South Africa. History The publication began as the ''Weekly Mail'', an alternative newspaper by a group of journalists in 1985 after the closure of two leading liberal newspapers, ''The Rand Daily Mail'' and ''Sunday Express''. ''Weekly Mail'' was one of the first newspapers to use Apple Mac desktop publishing. The ''Weekly Mail'' criticised the government and its apartheid policies, which led to the banning of the paper in 1988 by then State President P. W. Botha. The paper was renamed the ''Weekly Mail & Guardian'' from 30 July 1993. The London-based Guardian Media Group (GMG), the publisher of ''The Guardian'', became the majority shareholder of the print edition in 1995, and the name was ...

University Of Cape Town Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

South African Climatologists
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Ocean Chemistry
Marine chemistry, also known as ocean chemistry or chemical oceanography, is influenced by plate tectonics and seafloor spreading, turbidity currents, sediments, pH levels, atmospheric constituents, metamorphic activity, and ecology. The field of chemical oceanography studies the chemistry of marine environments including the influences of different variables. Marine life has adapted to the chemistries unique to earth's oceans, and marine ecosystems are sensitive to changes in ocean chemistry. The impact of human activity on the chemistry of the earth's oceans has increased over time, with pollution from industry and various land-use practices significantly affecting the oceans. Moreover, increasing levels of carbon dioxide in the earth's atmosphere have led to ocean acidification, which has negative effects on marine ecosystems. The international community has agreed that restoring the chemistry of the oceans is a priority, and efforts toward this goal are tracked as part o ...

Benguela Muds Marine Protected Area
The Benguela Muds Marine Protected Area is an offshore conservation region on the continental slope of the west coast in the exclusive economic zone of South Africa. History Purpose A marine protected area is defined by the IUCN as "A clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values". The MPA is intended to protect threatened remnants of mud habitats. Extent The MPA is about 50 nautical miles west of Saldanha Bay in the Western Cape. The protected area of ocean is 72 km2 in the 350 to 400 m depth zone. The water column, seabed, and subsoil are all part of the area protected. Boundaries The MPA is bounded by: *Northern boundary: S32°35’, E16°40’ to S32°35’, E16°44’ *Eastern boundary: S32°35’, E16°44’ to S32°43’, E16°49’ *Southern boundary: S32°43’, E16°49’ ...

University Of Cape Town
The University of Cape Town (UCT) ( af, Universiteit van Kaapstad, xh, Yunibesithi ya yaseKapa) is a public research university in Cape Town, South Africa. Established in 1829 as the South African College, it was granted full university status in 1918, making it the oldest university in South Africa and the oldest university in Sub-Saharan Africa in continuous operation. UCT is organised in 57 departments across six faculties offering bachelor's ( NQF 7) to doctoral degrees ( NQF 10) solely in the English language. Home to 30 000 students, it encompasses six campuses in the Capetonian suburbs of Rondebosch, Hiddingh, Observatory, Mowbray, and the Waterfront. Although UCT was founded by a private act of Parliament in 1918, the Statute of the University of Cape Town (issued in 2002 in terms of the Higher Education Act) sets out its structure and roles and places the Chancellor - currently, Dr Precious Moloi Motsepe - as the ceremonial figurehead and invests real leadership ...

Biological Pump
The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments.Sigman DM & GH Haug. 2006. The biological pump in the past. In: Treatise on Geochemistry; vol. 6, (ed.). Pergamon Press, pp. 491-528 In other words, it is a biologically mediated processes which result in the sequestering of carbon in the deep ocean away from the atmosphere and the land. The biological pump is the biological component of the "marine carbon pump" which contains both a physical and biological component. It is the part of the broader oceanic carbon cycle responsible for the cycling of organic matter formed mainly by phytoplankton during photosynthesis (soft-tissue pump), as well as the cycling of calcium carbonate (CaCO3) formed into shells by certain organisms such as plankton and mollusks (carbonate pump).
