Elizabeth Marchant Truswell FAA (also known as Elizabeth Kemp) is a former Chief Scientist at the Australian Geological Survey Organisation and is known for her application of recycled palynomorph distribution as an indicator of sub-ice geology.
Truswell was born in Kalgoorlie, Western Australia and completed a BSc (Hons) at the University of Western Australia in 1962. [1] In 1963 she received a British Commonwealth Scholarship to undertake a PhD at Cambridge University, UK. [1] She was awarded her PhD in 1966 on the geological history of flowering plants as demonstrated by the pollen record. [1] [2] In 2000, she completed a Visual Arts degree with Honours at the School of Art, Australian National University (ANU), focusing on the role of the artists who accompanied the early explorers to Antarctica. [3] [4]
Truswell's career has focused on the field of palynology, with a large part devoted to understanding Antarctica's floral history. She developed several novel methods for investigating sub-ice geology via the distribution of recycled pollen spores, leading to her election as a Fellow of the Australian Academy of Science in 1985. [2] [5]
As a postdoctoral researcher at Florida State University, US (1971–1973), Truswell participated in the first Deep Sea Drilling Program (DSDP) voyages to Antarctica, [6] which still holds the record for the furthest south of such drilling. This voyage contributed to a new understanding of the age of the Antarctic ice sheet and the development of an early version of the Antarctic Convergence. She was one of the only women on the voyage, and one of just a handful of women to participate in these early DSDP voyages. She recently published a book about the expedition - "A Memory of Ice". [7] Subsequent work on Ocean Drilling Program material led her, along with M.K. Macphail, to decipher an unparalleled pollen record from Prydz Bay, revealing the composition of terrestrial plant communities during the earliest stages of ice-cap formation during the Late Eocene preglacial-glacial transition. [8]
Truswell returned to Australia in 1973 to begin a career with the Bureau of Mineral Resources (now Geoscience Australia) [1] holding the position of Chief Research Scientist from 1990 to 1997. [9] During this time her work focused not only on the evolutionary and geological history of the Antarctic continent, but also on the past climatic conditions of Australia and applying the geological record to inform understanding of modern climate change. She was also a member of Australia's Antarctic Advisory Committee (1992–1998) and a board member of the first Antarctic Cooperative Research Centre in Hobart, the Antarctic Climate & Ecosystems Cooperative Research Centre.
Truswell has been involved in several UNESCO projects. Her first involvement was with the UNESCO Earth Science program (1991–1999), which aimed to help young Australian scientists take part in projects with people from developing countries. Since 2006 she has served on the Australian National Committee for the International Geoscience Co-operation (IGCP), which is part of the UNESCO International Geosciences Programme. [1] [10]
In 2000 Truswell shifted her emphasis towards the interface between science and the arts, with particular reference to Antarctica. During her time as a visiting fellow in the Research School of Earth Sciences at the Australia National University, she undertook a degree in visual arts at the School of Art. [3] Her artworks are held in a number of collections in Australia and Europe, including, in Canberra, at the ANU and at Geoscience Australia. She has exhibited in solo exhibitions at the ANCA Gallery in Canberra, CSIRO Discovery Centre, the Goldfields Regional Gallery, Kalgoorlie, and the ANU School of Art Gallery. Her public outreach has included talks and radio broadcasts (e.g. ABC Radio National, The Science Show), U3A lectures on Art and Science in Early Antarctic Exploration, and published papers in academic and popular literature.

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.
Microcachrys tetragona, known as creeping pine or creeping strawberry pine, is a species of dioecious conifer belonging to the podocarp family (Podocarpaceae). It is the sole species of the genus Microcachrys. The plant is endemic to western Tasmania, where it is a low shrub growing to 1 m tall at high altitudes. Its leaves are scale-like, arranged in opposite decussate pairs, superficially resembling those of the unrelated Diselma archeri (Cupressaceae). It shares the common name Creeping pine with several other plants. Females produce tiny, red, edible berries in summer.
Professor Dame Jane Elizabeth Francis, is the Director of the British Antarctic Survey. She previously worked as Professor of Palaeoclimatology at the University of Leeds where she also was Dean of the Faculty of Environment. In 2002 she was the fourth woman to receive the Polar Medal for outstanding contribution to British polar research. She is currently the Chancellor of the University of Leeds.

There may have been women in Antarctica, exploring the regions around Antarctica for many centuries. The most celebrated "first" for women was in 1935 when Caroline Mikkelsen became the first woman to set foot on one of Antarctica's islands. Early male explorers, such as Richard Byrd, named areas of Antarctica after wives and female heads of state. As Antarctica moved from a place of exploration and conquest to a scientific frontier, women worked to be included in the sciences. The first countries to have female scientists working in Antarctica were the Soviet Union, South Africa and Argentina.
