Benthic image library

Marine ecologists study the diversity and distribution of large benthic marine species in the Casey region. They hope to understand the natural variability of coastal Antarctic marine communities and how they might relate to changing environmental conditions such as

  • light
  • sea ice
  • water quality
  • sedimentation

Without this understanding of how and where the marine life lives naturally, any impacts of human activities on these marine communities cannot be clearly identified. To follow is a selection of photographs of some of the more common large benthic marine species encountered in the Casey region.
