Data to support Zooplankton abundance and distribution along the Mawson coast, East Antarctica - collected on the TEMPO voyage of the RV Investigator

The data describe all zooplankton species abundance values estimated at each rectangular midwater trawl (RMT 1+8) target and routine sampling site collected during the 2021 TEMPO voyage on R/V Investigator.
During the TEMPO voyage, zooplankton were collected using the RMT 1+8 plankton net and sorted down to the lowest taxonomic level possible. The supporting data set, in CSV format, feature abundances estimated from RMT+1 samples only.
The data file is named allzooplankton.csv. The fields (columns) in the file are:
"Site" – sampling site ID for each routine (RXX) and target (TXX) trawl using RMT1+8.
"Date" – date of each sample collected (ie. target or routine trawl) [dd/mm/yyyy].
"Latitude" – latitude of each trawl [degrees] (-dd.ddddd).
"Longitude" – longitude of each trawl [degrees] (dd.ddddd).
"Chla" – Integrated estimate of chlorophyll-a (mg m^-2) averaged at depths between 10 to 200 m, which aligns with the section of the water column where zooplankton were sampled.
"Depth" – Bathymetric depth estimated at each sampling station.
"MLD_03" – Mixed layer depth (m). Not used in final analysis.
"MLD_05" – Mixed layer depth (m). Not used in final analysis.
"MLD_N2max" – Mixed layer depth (m) where the N^2 maximum is found, i.e., the pycnocline.
"CT_200" – Absolute temperature (°C) averaged at depths between surface and 200 m maximum net sampling depth. Values are derived from in situ CTD measurements at each sampling site.
"SA_200" – Absolute salinity (g kg^-1) averaged at depths between surface and 200 m maximum net sampling depth. Values are derived from in situ CTD measurements at each sampling site.
"IceMeltDays" – Number of days since sea ice melted calculated from daily passive microwave estimated percent sea ice concentration taken from the National Snow and Ice Data Centre.
"m_to_Ice" – Distance (m) estimated from sampling site to edge of ice.
"IceConc" – Actual ice concentration value (%). It is the percentage of an area covered in sea ice.
