BROKE-West microbial concentrations - Voyage 3 of the Aurora Australis 2005/2006
Listed in NASA Earthdata CMR
This data set contains concentrations of phytoplankton, protozoa, total bacteria and metabolically active bacteria assessed by flow cytometry on transects 12, 1, 3, 5, 7, 9 and 11 of the BROKE-West survey of the Southern Ocean between January and March 2006.
Description
Only total bacterial concentrations were assessed for transect 11. Between 4 and 12 depths were sampled for marine microbes and concentrations were assessed using FACScan flowcytometer.
Phytoplankton were identified and counted based on the autofluorescense of chlorophyll a when excited by the 488 nm laser of the FACScan. Protozoa were identified and counted after staining with the acid vacuole stain Lysotracker Green. Total bacteria were identified and counted using the cell permeant SYTO 13 nucleic stain.

Metabolically active bacteria were identified and counted after staining for intracellular esterases with the esterase stain 6CFDA. The fields in this dataset are: Latitude Longitude Transect Number CTD number, flow file Depth (m) Total bacteria (per millilitre) Active bacteria (per millilitre) Dead bacteria (per millilitre) Protozoa (per millilitre) Phytoplankton (per millilitre) This work was completed as part of ASAC project 40 (ASAC_40).
