Research Theme A "Ocean & Climate"

The world ocean is a key player in the Earth's climate system. Surface and deep water circulation strongly influence the heat distribution around the globe and are, in turn, sensitive to global climate change. Research theme A "Ocean and Climate" focuses on these present, past, and future linkages and benefits from the synergy of three scientific fields:

  • Physical Oceanography - which investigates recent ocean circulation patterns and mechanisms
  • Paleoceanography - reconstructing past oceanographic and climatic conditions using a wide range of proxies
  • Climate and oceanographic modelling - simulation of past, present, and future conditions - model results of which can then be validated with instrumental and proxy data

Research Associate for Research Theme A: Dana Pittauer
