Krystyna Saunders

Research Scientist

Role at ANSTO 

Krystyna is a research scientist in the Environmental Change Program (Environment Theme). She specialises in reconstructing past climates and ecosystems from sedimentary lake records and works on a number of projects based on locations throughout the Southern Hemisphere, including sub-Antarctic islands, Tasmania, Chile and New Zealand. 

She  applies a variety of biological and geochemical techniques together with radiochemistry to develop climate and ecosystem records over the last ca. 12,000 years. These provide key insights into the natural variability of the study areas and, in most cases, show clear and unequivocal signals of human impacts over the last ca. 150 years. 

Topics include:

  • Past Southern Hemisphere westerly wind variability
  • High-resolution precipitation and temperature reconstructions using scanning techniques applied to lake sediments in Tasmania
  • Application of palaeoecological techniques in estuarine studies
  • Diatom surveys of sub-Antarctic Macquarie and Campbell Island lakes and ponds, and Tasmanian and southeast mainland Australian coastal waterbodies
  • Impacts of feral animals on sub-Antarctic lakes and their catchments
  • Impacts of mining on Tasmanian lakes and estuaries

Expertise 

Diatom classifications, physiochemical proxies for lakes, high-resolution climate reconstructions, palaeoclimatology, palaeoecology
