Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 4 of the Astrolabe - 2004/2005 samples

Locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2004/2005 season. Samples were collected between February and March of 2005.

The final dataset will contain information on chlorophyll, carotenoids, coccolithophorids and species identification and counts.

Public Summary from the project:

This program aims to determine the role of single celled plants, animals, bacteria and viruses in Antarctic waters. We quantify their vital role as food for other organisms, their potential influence in moderating global climate change through absorption of CO2 and production of DMS, and determine their response to effect of climate change.
