Research Theme C "Ocean & Life"

Marine ecosystems host countless numbers of life forms which actively and strongly impact the worlds element cycling of e.g. carbon, oxygen, methane, phosphorus, and nitrogen. In return, environmental changes impact, alter, or erase life in the world's ocean and coastal ecosystems.
PhD students in research theme C cover many fields of marine biology and bio-oceanography, investigating e.g.

  • the impact of marine life on biogeochemical cycles, covering a broad range of ecosystems from arctic seas to tropical waters and mangroves;
  • past and present microbial interaction with their environment, spanning a broad range from deep sea sediments to tropical corals; or
  • the response of marine ecosystems to (anthropogenic) environmental changes like e.g. ocean acidification and carbon sequestration.

Research Associate for Research Theme C: Martin Lukas
