PhD position: Changes in Antarctic and Subantarctic Shelf Benthos – Deadline 21 May 2023

PhD position: Changes in Antarctic and Subantarctic Shelf Benthos – Deadline 21 May 2023

Background

In contrast to the strong sea-ice decline in the Arctic Ocean, climate warming is affecting Subantarctic and Antarctic regions and their biota in different ways. Some areas in the Antarctic Peninsula and Subantarctic are warming fast, causing glacier retreat, sea-ice decline and ice-shelf collapse. But in large parts of the Antarctic, sea-ice cover has been stable or even increasing until less than a decade ago, affecting the timing and magnitude of food supply to the benthos, and the biodiversity and biomass of its unique biota. AWI scientists have carried out expeditions to the Antarctic and Patagonian region between the 1980s and 90s, respectively, and present. The comparision of historical stations visited on earlier cruises with recent Polarstern and Meteor expeditions using standardized methodology provides the to assess the changes in benthic biomass and composition in relation to the changes in sea-ice change, glacier and ice-shelf retreat, and physical disturbance (e.g. sedimentation, iceberg scouring).

Tasks

The department of Biosciences, section Bentho-Pelagic Processes, has a vacancy for a PhD (m/f/d) student to work on the temporal changes in Antarctic and Subantarctic benthic communities. You are expected to analyze temporal changes in macrofauna (grab samples) and mega-epifauna communities (video/photo material) communities, comparing stations from the Eastern Weddell Sea and the Beagle Channel. We are interested in (i) the effect of changing sea-ice cover on benthic communities (sea-ice cover increased between 1988 and 2014, and plummeted therafter), (ii) the patterns of benthic succession after ice-berg scour (BENDEX disturbance experiment), and (iii) the combined effects of glacial melt and anthropogenic change on the biodiversity and biomass of benthic communities (Fjordflux cruise). Research will involve state-of-the-art image analyses and spatial statistics methods and will be supervised by a Thesis Advisory Committee with senior scientists from four AWI sections.

Requirements

  • Master’s degree (or equivalent) in marine biology or related fields
  • Good knowledge of benthic biodiversity and major taxa
  • Proficiency in or willingness to learn image analysis and multivariate statistics/spatial ecology/GIS tools to analyze benthic community data
  • Excellent written and oral communication skills and proven ability to work in a team
  • Disposition to work in the laboratory, in the office and in the field

Additional skills and knowledge

  • Prior experience with benthic ecology, benthic sampling, identification and analyses methods are an important asset
