Laramie Potts is an American [ citation needed ] scientist who identified the Wilkes Land mass concentration in Antarctica in collaboration with Ralph von Frese. He is from South Africa.[ citation needed ] He is an associate professor in the School of Applied Engineering and Technology and teaches geomatics (surveying) at the New Jersey Institute of Technology (NJIT). [1]
Potts received his B.S. in Land Surveying in 1984 at the University of Cape Town, his M.S. (1993) and Ph.D. [2] (2000) in Geodetic Science and Surveying at The Ohio State University and an M.B.A. (2016) from the NJIT. [3]
He and von Frese used gravity measurements by NASA's GRACE satellites to identify a 200-mile (300 km) wide mass concentration. This mass anomaly is centered within a larger ring-like structure visible in radar images of the land surface beneath the Antarctic ice cap. This combination led these researchers to speculate that it may be the result of a large impact event. [4]
Potts is part of the leadership team at Northeast Consulting Group, LLC. [5]
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is washed by the Southern Ocean or, depending on definition, the southern Pacific, Atlantic, and Indian Oceans. It has an area of more than 14 million km2. Antarctica is the largest ice desert in the world.
An iceberg is a piece of freshwater ice more than 15 m long that has broken off a glacier or an ice shelf and is floating freely in open (salt) water. Smaller chunks of floating glacially-derived ice are called "growlers" or "bergy bits". The sinking of the Titanic in 1912 led to the formation of the International Ice Patrol in 1914. Much of an iceberg is below the surface, which led to the expression "tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard.
The climate of Antarctica is the coldest on Earth. The continent is also extremely dry, averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent, because of the katabatic winds. Most of Antarctica has an ice-cap climate with extremely cold and dry weather.
New Jersey Institute of Technology (NJIT) is a public research university in Newark, New Jersey with a graduate-degree-granting satellite campus in Jersey City. Founded in 1881 with the support of local industrialists and inventors especially Edward Weston, NJIT opened as Newark Technical School (NTS) in 1885 with 88 students. The school grew into a classic engineering college – Newark College of Engineering (NCE) – and then with the addition of a School of Architecture in 1973, into a polytechnic university that now hosts five colleges and one school. As of fall 2021 the university enrolls about 11,900 students from 83 countries, 2,500 of whom live on its main campus in Newark's University Heights district.
The Byrd Polar and Climate Research Center (BPCRC) is a polar, alpine, and climate research center at The Ohio State University founded in 1960.
The Gravity Recovery and Climate Experiment (GRACE) was a joint mission of NASA and the German Aerospace Center (DLR). Twin satellites took detailed measurements of Earth's gravity field anomalies from its launch in March 2002 to the end of its science mission in October 2017. The GRACE Follow-On (GRACE-FO) is a continuation of the mission on near-identical hardware, launched in May 2018.
Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory.
Thwaites Glacier, nicknamed the Doomsday Glacier, is an unusually broad and vast Antarctic glacier flowing into Pine Island Bay, part of the Amundsen Sea, east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. Its surface speeds exceed 2 kilometres per year near its grounding line. Its fastest-flowing grounded ice is centered between 50 and 100 kilometres east of Mount Murphy. In 1967, the Advisory Committee on Antarctic Names named the glacier after Fredrik T. Thwaites (1883–1961), a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison.
Wilkes Land crater is an informal term that may apply to two separate cases of conjectured giant impact craters hidden beneath the ice cap of Wilkes Land, East Antarctica. These are separated below under the heading Wilkes Land anomaly and Wilkes Land mascon (mass concentration), based on terms used in their principal published reference sources.
Ralph R. B. von Frese is an American geophysicist at the Ohio State University who identified the Wilkes Land mass concentration in Antarctica in collaboration with Laramie Potts.
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations.
Smyley Island is an Antarctic island lying off the Antarctic Peninsula. The island is 61 km (38 mi) long and from 13 to 34 km wide, and lies about 20 km (12 mi) north of Case Island. It connects to the Stange Ice Shelf and is separated from Alexander Island by the Ronne Entrance. Smyley Island is one of the 27 islands of Palmer Land, Antarctica.
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
Astrobiology Science and Technology for Exploring Planets (ASTEP) was a program established by NASA to sponsor research projects that advance the technology and techniques used in planetary exploration. The objective was to enable the study of astrobiology and to aid the planning of extraterrestrial exploration missions while prioritizing science, technology, and field campaigns.
