Christina Riesselman is an American paleoceanographer whose research focus is on Southern Ocean response to changing climate. [1] [2] [3]
After completing her bachelor's degree at the University of Nebraska-Lincoln in Geology and English in 2001, Riesselman spent time at the Joint Oceanographic Institution in Washington DC, then moved to Stanford for her PhD which was completed in 2011. [1]
Following postdoctoral work as a Research Scientist with the US Geological Survey, she moved to the University of Otago, New Zealand in 2013. [4]
Riesselman uses diatom micropaleontology and stable isotope geochemistry in marine sediments to examine the evolution of the Antarctic cryosphere through the Cenozoic. [5] [6] She also participates in collaborative investigations into the modern controls on phytoplankton community structure. [7]
Riesselman with her husband, Chris Moy, a University of Otago paleoclimatologist, are among the 30 researchers on the JOIDES Resolution. The aim of the voyage, according to Reisselman, is to figure out how ocean circulation behaved during past warmer climates, up to three million years ago. [8]
Riesselman won the inaugural L’Oréal-UNESCO Fellowship for Women in Science New Zealand in 2015. [4] [9] [10]

The Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport estimated at 100–150 Sverdrups, or possibly even higher, making it the largest ocean current. The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet.
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of 637,000 square kilometres (246,000 sq mi).
The Deep Sea Drilling Project (DSDP) was an ocean drilling project operated from 1968 to 1983. The program was a success, as evidenced by the data and publications that have resulted from it. The data are now hosted by Texas A&M University, although the program was coordinated by the Scripps Institution of Oceanography at the University of California, San Diego. DSDP provided crucial data to support the seafloor spreading hypothesis and helped to prove the theory of plate tectonics. DSDP was the first of three international scientific ocean drilling programs that have operated over more than 40 years. It was followed by the Ocean Drilling Program (ODP) in 1985, the Integrated Ocean Drilling Program in 2004 and the present International Ocean Discovery Program in 2013.
Lake Fryxell is a frozen lake 4.5 kilometres (2.8 mi) long, between Canada Glacier and Commonwealth Glaciers at the lower end of Taylor Valley in Victoria Land, Antarctica. It was mapped in the early 1900s and named during Operation Deep Freeze in the 1950s. There are several forms of algae living in the waters and a weather station located at the lake.
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.
The Naturaliste Plateau is one of several large submarine plateaus extending from Western Australia into the Indian Ocean. It is a rectilinear plateau that covers an area of 90,000 square kilometres. Its width is about 400 kilometres (250 mi) east-west and 250 km (160 mi) north-south. The water depths are from 1500 to 5000 metres.
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).
ANDRILL is a scientific drilling project in Antarctica gathering information about past periods of global warming and cooling.

Richard Levy is a New Zealand glacial stratigrapher and paleoclimatologist with expertise in microfossil analysis. As a principal scientist at GNS Science he has been involved in international and New Zealand environmental research programmes focussing on the evolution of the Earth's climate and building an understanding of the role of greenhouse gases in causing anthropogenic climate changes, in particular those impacting global sea levels. He has had extensive experience in scientific drilling, leading major projects, including the ANtarctic geological DRILLing (ANDRILL) Program in Antarctica. Since 2018, Levy has co-led the government funded NZ SeaRise programme.
Robert Murray McKay is a paleoceanographer who specialises in sedimentology, stratigraphy and palaeoclimatology, specifically gathering geological evidence to study how marine-based portions of the Antarctic ice sheet behave in response to abrupt climate and oceanic change. He has been involved in examination of marine sedimentary records and glacial deposits to show melting and cooling in Antarctica over the past 65 million years and how this has influenced global sea levels and climate. This has helped climate change scientists overcome uncertainty about how the ice sheets will respond to global warming and how this can be managed effectively in the 21st century. He has participated in international projects including ANDRILL and the International Ocean Discovery Program (IODP), led major New Zealand government-funded research teams and has received several awards in recognition of his work. Since 2012 McKay has been an associate professor at Victoria University of Wellington and from 2019, director of the Antarctic Research Centre.
