There are uncorrected errors in lat/lon/time/sample event code. These will be flagged and corrected in a quality controlled version of the log. Where there is a large discrepency between start lat/lon and interpolated lat/lon, the latter may be considered to be more accurate. Refer to the eventlog_matchup.html file for details of lat/lon interpolation.These data are publicly available from the provided URL.This information has not been quality controlled or error corrected. Please use the information with caution. We recommend using the quality controlled log when it becomes available.

Each sampling event was recorded by scientists and technical support staff in a logbook that was kept in the operations room on board the Aurora Australis. This is a direct digital transcription of the paper logbook with interpolated lat/lon from underway data to supplement start times as recorded in the log. The method used to obtain the supplementary position is described in the associated eventlog_matchup.html file.
event_number: A unique event identifier in the log, in the order that the events were written down (usually but not always chronologically)
event_type: The code defined and used by each research project to identify the types of equipment deployed or samples collected for an event.
event_type_prefix: A non-mandatory prefix field used by some research projects to identify the type of an event
event_type_number: A sequential number or alphanumeric-number combination defined and used by each research project to identify unique equipment deployment or sample collection events
station_number: A universal (voyage-wide) station number used across all projects to identify a nominal lat/lon position defined during voyage planning
leg: A nominally straight-line section of the voyage track defined during voyage planning. The voyage track was planned as a series of roughly N-S and E-W transects that intersected in some locations. Legs start at a station and continue through more stations to a vertex-station which is the start of the next leg. Legs are numbered consecutively.
waypoint: A GPS waypoint used by Aurora Australis crew, AAD science technical support and researchers to identify target lat/lon positions in the voyage. Some waypoints correspond with station numbers.
start_date_utc: The start date of the event in UTC
start_time_utc: The start time of the event in UTC
start_lat_deg: The latitude (whole degrees) of the vessel at the beginning of the event
start_lat_min: The latitude (minutes) of the vessel at the beginning of the event
start_lat_dec_deg: The latitude (decimal degrees) of the vessel at the beginning of the event
start_lon_deg: The longitude (whole degrees) of the vessel at the beginning of the event
start_lon_min: The longitude (minutes) of the vessel at the beginning of the event
start_lon_dec_deg: The longitude (decimal degrees) of the vessel at the beginning of the event
end_date_utc: The end date of the event in UTC
end_time_utc: The end time of the event in UTC
end_lat_deg: The latitude (whole degrees) of the vessel at the end of the event
end_lat_min: The latitude (minutes) of the vessel at the end of the event
end_lat_dec_deg: The latitude (decimal degrees) of the vessel at the end of the event
end_lon_deg: The longitude (whole degrees) of the vessel at the end of the event
end_lon_min: The longitude (minutes) of the vessel at the end of the event
end_lon_dec_deg: The longitude (decimal degrees) of the vessel at the end of the event
remarks: Comments/remarks written by researchers when completing the paper log
transcribe_comments: Comments/remarks made by the transcriber when the log was digitised
utc: The start date and time of the event in UTC
start_lon_dec_deg_interp: The latitude (decimal degrees) of the vessel at the beginning of the event interpolated from the vessel underway data
start_lat_dec_deg_interp: The longitude (decimal degrees) of the vessel at the beginning of the event interpolated from the vessel underway dataThe science event log is a record of the date, time, location, event code (assigned by projects) and if relevant the K-Axis station number where every science sampling event occurred. It is a reference point for scientists to disover what types of data were collected at each location during the voyage for collaboration purposes, and a backbone reference log for ecological studies. Interpolated lat/lon for the start time of each event fill gaps where the position was omitted or overlooked by scientists filling in the log.GET DATAhttps://data.aad.gov.au/eds/4268/downloadDownload point for the event logVIEW RELATED INFORMATIONhttps://data.aad.gov.au/aadc/metadata/citation.cfm?entry_id=AAS_4344_K-AXIS_Science_Event_Log_UW_LatLonCitation reference for this metadata record and dataset.PROJECT HOME PAGEhttps://secure3.aad.gov.au/proms/public/projects/report_project_public.cfm?project_no=AAS_4344Public information for AAS project AAS_4344AAS_4344_K-AXIS_VoyageNot providedScience AssociatedAMD/AUAMDCEOSCEOS IDN DIFVERSION 10.22016-09-072019-04-021970-01-01T00:00:001970-01-01T00:00:00Not provided
