This dataset contains locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2007/2008 season. Samples were collected between February and March of 2008. 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). The fields in this dataset are: Tube label Date(UTC) Time(UTC) Local time (dec hrs)actual solar local time (decimal hours) calc from longitude DOES NOT EQUAL TIME ZONE Longitude decimal degrees/degrees, minutes Latitude decimal degrees/degrees, minutes Sea Temperature degrees Celsius Ice present/absent Lugol's bottle # - microscope sample number for phytoplankton ID (Our use only) HPLC Volume remaining - volume filtered for HPLC pigment analysis (Our use only) Volume filtered for HPLC Volume remaining for Coccoliths Coccolith tray No.(Our use only) Coccolith tray position number Net Sample Time Fluorescence
