This dataset contains locations of sampling sites for ASAC project 40 on voyage 3 of the Aurora Australis in the 2004/2005 season. Samples were collected between December and February of 2004/2005. It also contains 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. For more information, see the other metadata records related to ASAC project 40 (ASAC_40). There are three spreadsheets in this download file - one for the CLIVAR I9 transect, and another for a survey in the region of the Princess Elizabeth Trough. A third spreadsheet contains pigment data. Each spreadsheet contains several worksheets. PET - CTD Station details, CTD profiles, CTD Surface Samples. I9 - CTD Station details, CTD profiles, CTD Surface Samples, Transect Surface Samples. CLIVAR_CTD_Pigs_CHEMTAX - Pigment data: Concentrations of various pigments (ug/L) analysed by HPLC (see protocol); Interpretation: Interpretation of pigment data using CHEMTAX to estimate the amount (ug/L) of chlorophyll a present in a range of algal types. There is also a word document detailing some of the HPLC procedures used. The fields in this dataset are: Station Latitude Longitude Time (Universal Time) Sounder depth Sounder offset Bottles Depths (dB) Label Fmax Tmin HPLC Fluorescence FCM Visc/TEP Phyto ID Lugols Glut Bacteria Water Temperature Salinity Conductivity Net Sample Depth (m) Species Chlorophyll a Pigments HPLC
