Abstract:
Project Objectives
1) To describe trophic relationships in near shore marine benthic ecosystems of East Antarctica and determine the importance of environmental forces (such as sea ice and primary production) to the structure of food webs and biological interactions in benthic assemblages. 2) To determine how marine benthic food webs in East Antarctica respond to local scale disturbances (such as sewage outfalls and abandoned waste disposal sites) and develop predictive models of the influence of local human activities on trophic relationships. Collections of organisms from coastal ecosystems around Casey and Davis stations were made between 2006/07 and 2010/11. Purpose: This is the master DIF for the stable isotope data from the TRENZ project, within which there are several data sets. Stable isotope data was used to infer trophic position and food web base sources for marine organisms from coastal ecosystems of Casey and Davis areas.
