Timothy George Haskell NZAM is a New Zealand scientist.
Haskell completed a PhD at the University of Canterbury in 1972 under the supervision of Brian Wybourne. [1] 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. [2] He had equipment mounted on the Erebus Glacier Tongue when it calved in 1990. [3] He had just finished a field trip to the glacier in 2010 when it next calved. [4]
He worked with Paul Callaghan for a time, developing portable Nuclear magnetic resonance (NMR) technology. Initial application to the determination of sea ice heterogeneity [5] 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. [6]
Ross Island is an island in Antarctica lying on the east side of McMurdo Sound and extending 43 nautical miles from Cape Bird in the north to Cape Armitage in the south, and a similar distance from Cape Royds in the west to Cape Crozier in the east. The island is entirely volcanic. Mount Erebus, 3,795 metres (12,451 ft), near the center, is an active volcano. Mount Terror, 3,230 metres (10,600 ft) about 20 nautical miles eastward, is an extinct volcano. Mount Bird rises to 1,765 metres (5,791 ft) just south of Cape Bird.
Mount Erebus is the southernmost active volcano on Earth, located on Ross Island in the Ross Dependency in Antarctica. With a summit elevation of 3,792 metres (12,441 ft), it is the second most prominent mountain in Antarctica and the second-highest volcano in Antarctica. It is the highest point on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. It makes Ross Island the sixth-highest island on Earth.
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 platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers. Ice shelves form along coastlines where the ice thickness is insufficient to displace the more dense surrounding ocean water. The boundary between the ice shelf (floating) and grounded ice is referred to as the grounding line; the boundary between the ice shelf and the open ocean is the ice front or calving front.
The McMurdo Sound is a sound in Antarctica, known as the southernmost passable body of water in the world, located approximately 1,300 kilometres (810 mi) from the South Pole.
This is a timeline of the history of New Zealand's involvement with Antarctica.
Iceberg B-15 was the largest recorded iceberg by area. It measured around 295 by 37 kilometres, with a surface area of 11,000 square kilometres, about the size of the island of Jamaica. Calved from the Ross Ice Shelf of Antarctica in March 2000, Iceberg B-15 broke up into smaller icebergs, the largest of which was named Iceberg B-15-A. In 2003, B-15A drifted away from Ross Island into the Ross Sea and headed north, eventually breaking up into several smaller icebergs in October 2005. In 2018, a large piece of the original iceberg was steadily moving northward, located between the Falkland Islands and South Georgia Island. As of August 2023, the U.S. National Ice Center (USNIC) still lists one extant piece of B-15 that meets the minimum threshold for tracking. This iceberg, B-15AB, measures 20 km × 7 km ; it is currently grounded off the coast of Antarctica in the western sector of the Amery region.
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.
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.
The Erebus Glacier 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 glacier tongue.
Timothy Raymond Naish is a New Zealand glaciologist and climate scientist who has been a researcher and lecturer at Victoria University of Wellington and the director of the Antarctic Research Centre, and in 2020 became a programme leader at the Antarctic Science Platform. Naish has researched and written about the possible effect of melting ice sheets in Antarctica on global sea levels due to high CO2 emissions causing warming in the Southern Ocean. He was instrumental in establishing and leading the Antarctica Drilling Project (ANDRILL), and a Lead Author on the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (2014).
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.
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 a British-New Zealand 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, a New Zealand Antarctic researcher. She 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. In 2023, she was appointed Deputy Director of the N.Z. Antarctic Science Platform.
