Timothy George Haskell NZAM is a New Zealand scientist.
Haskell started his career at the Physics and Engineering Laboratory of DSIR (New Zealand) and remained with them through its evolution to Industrial Research Limited (IRL). He shifted to Callaghan Innovation in 2012.
He worked with Bill Robinson on the development and installation of earthquake base isolation foundations for Te Papa. However, he is best known for his development of "Camp Haskell" - a containerised facility for working on the Sea ice of McMurdo Sound. [1] He had equipment mounted on the Erebus Glacier Tongue when it calved in 1990. [2] He had just finished a field trip to the glacier in 2010 when it next calved. [3]
He worked with Paul Callaghan for a time, developing portable Nuclear magnetic resonance (NMR) technology. Initial application to the determination of sea ice heterogeneity [4] evolved to become a range of bench-top NMR devices developed by the spin-off company Magritek.
In 2009 the ocean passage between Ross Island and White Island (Ross Archipelago) was named Haskell Strait, Antarctica. [5]
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand.
Mount Erebus is the second-highest volcano in Antarctica, the highest active volcano in Antarctica, and the southernmost active volcano on Earth. It is the sixth-highest ultra mountain on the continent. With a summit elevation of 3,794 metres (12,448 ft), it is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova.
The Ross Ice Shelf is the largest ice shelf of Antarctica. It is several hundred metres thick. The nearly vertical ice front to the open sea is more than 600 kilometres (370 mi) long, and between 15 and 50 metres high above the water surface. Ninety percent of the floating ice, however, is below the water surface.
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice that feeds it is the grounding line. The thickness of ice shelves can range from about 100 m (330 ft) to 1,000 m (3,300 ft).
This is a timeline of the history of New Zealand's involvement with Antarctica.
The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, 240 kilometres (150 mi) north of Ross Island. The Drygalski Ice Tongue is stable by the standards of Antarctica's icefloes, and stretches 70 kilometres (43 mi) out to sea from the David Glacier, reaching the sea from a valley in the Prince Albert Mountains of Victoria Land. The Drygalski Ice Tongue ranges from 14 to 24 kilometres wide.
Aviator Glacier is a major valley glacier in Antarctica that is over 60 miles (97 km) long and 5 miles (8.0 km) wide, descending generally southward from the plateau of Victoria Land along the west side of Mountaineer Range, and entering Lady Newnes Bay between Cape Sibbald and Hayes Head where it forms the Aviator Glacier Tongue.
Thwaites Glacier is an unusually broad and vast Antarctic glacier located east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. It was initially sighted by polar researchers in 1940, mapped in 1959–1966 and officially named in 1967, after the late American glaciologist Fredrik T. Thwaites. The glacier flows into Pine Island Bay, part of the Amundsen Sea, at surface speeds which exceed 2 kilometres (1.2 mi) per year near its grounding line. Its fastest-flowing grounded ice is centered between 50 and 100 kilometres east of Mount Murphy. Like many other parts of the cryosphere, it has been adversely affected by climate change, and provides one of the more notable examples of the retreat of glaciers since 1850.
Totten Glacier is a large glacier draining a major portion of the East Antarctic Ice Sheet, through the Budd Coast of Wilkes Land in the Australian Antarctic Territory. The catchment drained by the glacier is estimated at 538,000 km2 (208,000 sq mi), extending approximately 1,100 km (680 mi) into the interior and holds the potential to raise sea level by at least 3.5 m (11 ft). Totten drains northeastward from the continental ice but turns northwestward at the coast where it terminates in a prominent tongue close east of Cape Waldron. It was first delineated from aerial photographs taken by USN Operation Highjump (1946–47), and named by Advisory Committee on Antarctic Names (US-ACAN) for George M. Totten, midshipman on USS Vincennes of the United States Exploring Expedition (1838–42), who assisted Lieutenant Charles Wilkes with correction of the survey data obtained by the expedition.
The Erebus Ice Tongue is a mountain outlet glacier and the seaward extension of Erebus Glacier from Ross Island. It projects 11 kilometres (6.8 mi) into McMurdo Sound from the Ross Island coastline near Cape Evans, Antarctica. The glacier tongue varies in thickness from 50 metres (160 ft) at the snout to 300 metres (980 ft) at the point where it is grounded on the shoreline. Explorers from Robert F. Scott's Discovery Expedition (1901–1904) named and charted the ice tongue.
Sir Paul Terence Callaghan was a New Zealand physicist who, as the founding director of the MacDiarmid Institute for Advanced Materials and Nanotechnology at Victoria University of Wellington, held the position of Alan MacDiarmid Professor of Physical Sciences and was President of the International Society of Magnetic Resonance.
Erebus Glacier is a glacier draining the lower southern slopes of Mount Erebus, Ross Island, Antarctica. It flows west to Erebus Bay where it forms the floating Erebus Glacier Tongue. It was named in association with Mount Erebus by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott.
The New Zealand Antarctic Medal was created 1 September 2006, as a New Zealand royal honour to replace the British Polar Medal.
Peter John Barrett is a New Zealand geologist who came to prominence after discovering the first tetrapod fossils in Antarctica in 1967.
The Marsden Medal is a yearly award given by the New Zealand Association of Scientists. It is named after Sir Ernest Marsden and honours "a lifetime of outstanding service to the cause or profession of science, in recognition of service rendered to the cause or profession of science in the widest connotation of the phrase." It rivals the Rutherford Medal from the Royal Society of New Zealand.
Haskell Strait refers to the ocean passage in southern McMurdo Sound, running between Cape Armitage, Ross Island and Cape Spencer-Smith, White Island, Antarctica. Oceanographically, it separates McMurdo Sound from the ocean basin beneath the Ross Ice Shelf. The Strait itself is around 25 km wide and in places over 900 m deep. Currents of nearly half a knot have been measured in the Strait, although typical flows are lower. It is mostly covered by the ice of the McMurdo Ice Shelf and fast ice in southern McMurdo Sound. On rare occasions sea-ice breakout exposes the north-west corner of the Strait which becomes navigable and vessels can actually moor off Scott Base.
Patricia Jean Langhorne is an Antarctic sea ice researcher. She retired as Professor in the physics department at the University of Otago, New Zealand in 2020. She was previously head of department (2012–2015). She was New Zealand's leading sea ice physicist. For a time she led the observational component of one of New Zealand’s National Science Challenges – the Deep South.
Margaret Ann Bradshaw is a New Zealand geologist and a retired staff member at the University of Canterbury. She is considered a trailblazer and influential female role model in Antarctic research.
Natalie Robinson, an Antarctic researcher, is based at the National Institute of Water and Atmospheric Research in New Zealand. She led the final two K131 Science Events on the sea ice of McMurdo Sound, Antarctica.
