Metadata details
BROKE-West_viralabundance
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
Data acquisition
Samples were collected at the 3 sites at 9 different depths.
Depths included the bottom depth as well as 8 samples in the top 200M.
50ml samples were collected from the niskin bottles attached to the CTD.
20ml was filtered through a 0.02 microlitre filter to remove the viruses and larger organisms from the sample.
1ml of this virus free water was then pipetted into individual cryovials.
A further 1ml was then taken from the original seawater sample and was then passed through a 0.2 microlitre filter, which retained all the bacteria and algae.
The 0.2 microlitre filter was then placed in the cryovial with the 1ml of virus free seawater.
Samples were then fixed with glutaraldehyde (5 microlitre, 50% concentration) at hourly intervals for 4 hours.
After fixation samples were placed in liquid nitrogen and later stored at -80 degrees C.
All samples will be analysed using a flowcytometer.
The fields in these datasets are:
Date
Leg number
Latitude
Longitude
Subsample
Depth (m)
Bottle Number
Viscosity (cP)
This work was completed as part of ASAC projects 2655 and 2679 (ASAC_2655, ASAC_2679).
Quality
Samples were taken at 3 stations along leg 1.
9 depths were sampled at the 3 sites and depths were chosen based on the fluorescence maximum on the downcast of the CTD.
