The effect of global climate change on Antarctic marine diatoms

On each occasion water from the ship's online seawater tap was filtered through a 20 micrometre plankton net for up to one hour into a sample jar. A portion of the sample was preserved in lugol's iodine for later phytoplankton analysis, and the rest of the sample maintained alive in the dark in seawater at a constant low temperature. The live sample is maintained at the AAD for culturing and environment manipulation and competition experiments.

Project 2302 Twenty-two water samples were collected from 24/10/02 to 11/11/02, in open seawater between 53 degrees 50 degrees S and 65 degrees 50 degrees S. At each site, the following were recorded from the ship's data logger: latitude, longitude, date, UCT time, local time, water depth, salinity, water temperature, chlorophyll A, UV radiation, and conductivity.
