In 1985, the Nella Dan was trapped in sea ice for several weeks while undertaking a marine science voyage. During the time it was trapped, iceberg drift was measured in the region, tracking the movement of several icebergs relative to the ship. Iceberg movements included mt biscoe angle, bearing, and ship position so can get rotations with redundancy. Observations were done several times a day. The physical logs are archived at the Australian Antarctic Division.

This data set was collected during an ocean acidification mesocosm experiment performed at Davis Station, Antarctica during the 2014/15 summer season. It includes: - description of methods for all data collection and analyses. - diatom cell volume - bulk silicification - species specific silicification via fluorescence microscopy - bulk community Fv/Fm on day 12 - single-cell PAM fluorometry data (maximum quantum yield of PSII: Fv/Fm) A natural community of Antarctic marine microbes from Prydz Bay, East Antarctica were exposed to a range of CO2 concentrations in 650 L minicosms to simulate possible future ocean conditions up to the year ~2200. Diatom silica precipitation rates were examined at CO2 concentrations between 343 to 1641 micro atm, measuring both the total diatom community response and that of individual species, to determine whether ocean acidification may influence future diatom ballast and therefore alter carbon and silica fluxes in the Southern Ocean. Described and analysed in: Antarctic diatom silicification diminishes under ocean acidification (submitted for review) Methods described in: Antarctic diatom silicification diminishes under ocean acidification (submitted for review) Location: Prydz bay, Davis Station, Antarctica (68 degrees 35'S, 77 degrees 58' E) Date: Summer 2014/2015 Worksheet descriptions: Bulk silicification - raw data Measured total and incorporated biogenic silica using spectrophotometer for all tanks on day 12 after 24 h incubation with PDMPO - raw data Bulk Fv/Fm - dark-adapted maximum quantum efficiency of PSII (Fv/Fm) on whole community - raw data Measured Fv/Fm of individual cells from 3 mesocosm tanks.

These data tables were scanned by Fiona Gleadow. The data relate to diving petrels (Pelecanoides) from Heard Island, and generally appear to be measurements of body parts (weight, wing, tail, beak, tarsus, toe) on males and females, as well as measurements of eggs (weight, length and width).

Two components. The first component is an even log for all station and instrument deployements. The second component is a log where start and end bottom times need to be recorded for instruments for example the benthic trawl. There is one file for each of the logs. Both logs need to be ideally merged into one to have one data source of event information. The start and end bottom times need to ideally go into the event logging system on the ship. 1) Event log for stations and all instrument deployments Stations and instrument deployments were recorded (including failures) over the progress of the voyage to provide a summary of all work carried out over voyage and and assigned an Event ID number for referencing data associated with these events. Data_Format Data was initially recorded in the ship board PostgreSQL database. Data was exported as a comma delimited file 'events.csv' at the end of the voyage. Column 1 - Setcode (voyage identifier of the form 200708030 meaning year 2007-08, voyage 3) Column 2 - Voyage Code (text voyage identifier) Column 3 - Transect ID (transect identifier, no transects were identified this voyage) Column 4 - Station ID (Station identifier, blank for events not associated with a station, CEAMARC project stations are pre-pended with 'CEAMARC', CASo stations are pre-pended with 'CASO', sampling near icebergs for trace metals pre-pended with 'ICEBERG', woCE SR3 transect sampling pre-pended with 'SR3'). Column 5 - Event ID (unique ID across voyage for individual events) Column 6 - Event Type (usually the instrument deployed, self explanatory. One event type 'Plankton Water Sample' refers to mass water sampling undertaken for genomics work). Column 7 - User Reference (id used by individual scientists to reference their data for this event. If left blank they are using the auto assigned event id from this table). Column 8 - Start Timestamp (start timestamp of the event in UTC). Column 9 - Start Latitude (start latitude of the event from the ship gps) Column 10 - Start Longitude (start longitude of the event from the ship gps) Column 11 - Start Bottom Depth (bottom depth at the start time of the event in metres from EK60 sounder bathymetry export) Column 12 - End Timestamp (end timestamp of the event in UTC) Column 13 - End Latitude (end latitude of the event from the ship gps) Column 14 - End Longitude (end longitude of the event from the ship gps) Column 15 - Duration (duration of the event in hours) Column 16 - End Bottom Depth (bottom depth at the end time of the event in metres from EK60 sounder bathymetry export) Column 17 - Min bottom Depth (minimum bottom depth encountered over event period from EK60 sounder bathymetry export) Column 17 - Avg Bottom Depth (average bottom depth encountered over event period from EK60 sounder bathymetry export) Column 18 - Max Bottom Depth (maximum bottom depth encountered over event period from EK60 sounder bathymetry export) Column 19 - Author (person who entered event details into logging system) Column 20 - Notes (notes peculiar to the event, may be blank) 2) Log of instrument bottom times. Excel spreadsheet 'Trawl_log_18_Jan_08_final.xls' Column A - Station number, these are all CEAMARC station numbers, matching stations in the event log pre-pended by 'CEAMARC'. Column B - Event ID (matching event log, sometimes blank as this log an contain entries on intended events that did not get carried out for some reason or another) Column C - Trawl Name (labelled trawl name, actually event type as the log started off with just trawl start/end bottom times, but was expanded to encompass other event types like grabs etc.) Column D - Date of the event. Column E - Ship Speed (in knots from displays of gps speed). Column F - Time instrument hit the water in utc Column G - Time instrument reached the bottom in utc. Column H - Time instrument left the bottom (i.e. hauling started) in utc. Column I - Time instrument on the deck (ie out of the water) Column J - Depth in meters read of EK60 sounder display (could be any time during event). Column K - Comments pertaining to the event.

A scanned report and some data on scientific work carried out on a species of wingless fly on Heard Island. Taken from the report: During a years stay at Heard Island (1951) the opportunity was taken of carrying out a number of physiological experiments upon one of the three dipterous species present. For these experiments it was decided to use samples of Calycopteryx moseleyi minor since these were present around the camp in sufficient numbers to be conveniently collected. Observations were of two kinds (1) Those carried out in the field (2) Laboratory experiments. The first included the determination of the life history of the species together with details of its food, normal habitat and other pertinent data whilst the latter consisted of thermal, phototaxic and environmental experiments. Naturally conditions on an Antarctic field station are not propitious for accurate physiological experiments since both climatic conditions and lack of technical apparatus present difficult obstacles. However, the animals concerned are of such interest to comparative physiologists that the limiting factors of the experiments become relatively unimportant.
