Harry Godwin
Sir Harry Godwin, FRS (9 May 1901 – 12 August 1985) was a prominent English botanist and ecologist of the 20th century. He is considered to be an influential peatland scientist, who coined the phrase "peat archives" in 1981. He had a long association with Clare College, Cambridge. Early life Godwin was born in Yorkshire and soon after moved to Long Eaton, Derbyshire. He had a successful school career and gained a scholarship to Clare College, Cambridge in 1918, gaining his PhD in 1926. He was to be closely involved with Clare College for the rest of his life. It was at this time that he first made friends with the ecologist Arthur Tansley who was to be an important influence on Godwin for many years. Work In the early 1930s Harry and his wife Margaret were "dynamic botanists" who, together with the archaeologist Grahame Clark, led a small group of young academics at the University of Cambridge which aimed to gain a deeper understanding of the environment of past societies by ...

Grahame Clark
Sir John Grahame Douglas Clark (28 July 1907 – 12 September 1995), who often published as J. G. D. Clark, was a British archaeologist who specialised in the study of Mesolithic Europe and palaeoeconomics. He spent most of his career working at the University of Cambridge, where he was appointed Disney Professor of Archaeology from 1952 to 1974 and Master of Peterhouse from 1973 to 1980. Born in Kent to an upper-middle-class family, Clark developed an early interest in archaeology through his collection of prehistoric flint tools. After an education at Marlborough College, he proceeded to Peterhouse in the University of Cambridge, there attaining both his undergraduate and then doctoral degree. For the latter, he produced a thesis and published monograph focusing on Mesolithic Britain. In 1932 he co-founded the Fenland Research Committee, through which he excavated several prehistoric sites in the East Anglian Fens. He was also a senior member of the Prehistoric Society of E ...

Council For British Archaeology
The Council for British Archaeology (CBA) is an educational charity established in 1944 in the UK. It works to involve people in archaeology and to promote the appreciation and care of the historic environment for the benefit of present and future generations. It achieves this by promoting research, conservation and education, and by widening access to archaeology through effective communication and participation. History and objectives The origins of the CBA lie in the Congress of Archaeological Societies, founded in 1898, but it was in 1943, with the tide of war turning, that archaeologists in Britain began to contemplate the magnitude of tasks and opportunities that would confront them at the end of hostilities. In London alone more than 50 acres of the City lay in ruins awaiting redevelopment, while the historic centres of Bristol, Canterbury, Exeter, Southampton, and many other towns had suffered devastation. In response to a resolution from the Oxford Meeting of the Society ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Godwin Plots
The Godwin Plots are one of the world's longest running science experiments. They can be found at Wicken Fen nature reserve, Cambridgeshire, England. Five experimental areas of vegetation were established in the 1927 by Prof. Sir Harry Godwin. The first plot is never cut. The second is cut every four years, the next every three years and so on. Godwin completed his experiment in 1940, and the plots were left uncut, but the same plots were restored in 1954, and have been managed in accordance with Godwin's original methodology since that time. The cutting is undertaken in November/December every year. This management has, over many years, produced different vegetation patterns. Godwin used the experiment to demonstrate that management alone can change plant communities - an idea which is almost universally accepted today, but was quite radical in the early 20th century. Because of this work, the Plots, or Wicken Fen generally, are sometimes referred to as 'The birthplace of moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridgeshire
Cambridgeshire (abbreviated Cambs.) is a Counties of England, county in the East of England, bordering Lincolnshire to the north, Norfolk to the north-east, Suffolk to the east, Essex and Hertfordshire to the south, and Bedfordshire and Northamptonshire to the west. The city of Cambridge is the county town. Following the Local Government Act 1972 restructuring, modern Cambridgeshire was formed in 1974 through the amalgamation of two administrative counties: Cambridgeshire and Isle of Ely, comprising the Historic counties of England, historic county of Cambridgeshire (including the Isle of Ely); and Huntingdon and Peterborough, comprising the historic county of Huntingdonshire and the Soke of Peterborough, historically part of Northamptonshire. Cambridgeshire contains most of the region known as Silicon Fen. The county is now divided between Cambridgeshire County Council and Peterborough City Council, which since 1998 has formed a separate Unitary authorities of England, unita ...

Wicken Fen
Wicken Fen is a biological Site of Special Scientific Interest west of Wicken in Cambridgeshire. It is also a National Nature Reserve, and a Nature Conservation Review site. It is protected by international designations as a Ramsar wetland site of international importance, and part of the Fenland Special Area of Conservation under the Habitats Directive. A large part of it is owned and managed by the National Trust. It is one of Britain's oldest nature reserves, and was the first reserve cared for by the National Trust, starting in 1899.. The first parcel of land for the reserve was donated to the Trust by Charles Rothschild in 1901. The reserve includes fenland, farmland, marsh, and reedbeds. Wicken Fen is one of only four wild fens which still survive in the enormous Great Fen Basin area of East Anglia, where 99.9% of the former fens have now been replaced by arable cultivation. Reserve Management Although Wicken Fen is often described as if it were a natural wildernes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
