context_page_description: Leanne Armand is a marine scientist and an expert in the identification of diatoms in the Southern Ocean. She is known for her contributions to the understanding of past Southern Ocean dynamics and sea ice as a result of her knowledge of diatom distributions and ecology.
  Her research focuses on the distribution of diatoms, a single-cell microscopic phytoplankton, within the Southern Ocean. Different species of diatoms inhabit different regions of the ocean, depending on the physical characteristics of the water mass. Understanding diatom distributions and how their skeletons are preserved in the fossil record contained within sediment cores taken from the ocean floor can provide information about past climate regimes, including ocean temperatures and sea ice extent. Armand has also recently studied diatoms in the Southern Ocean near Kerguelen and Heard Islands to examine their role in the transport of carbon to the ocean floor after their annual spring bloom.
