K-Axis Science Event Log - scanned copy of paper original

Entry ID: AAS_4344_K-AXIS_Science_Event_Log_Scanned

Summary

Abstract: During the K-Axis marine voyage from mid Jan-late Feb 2016, a diverse range of sampling techniques were employed to collect specimens and data. 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 PDF of the scanned original document, compiled on paper during the voyage.

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

Purpose: The 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. The scanned copy of the log supplements the digitised version, also available and is intended for the use of researchers who want to check the original handwritten document.

Quality

This is a scanned copy of the original paper document compiled during the voyage. Some handwritten information is difficult to decipher. There are uncorrected errors in lat/lon/time/sample event code. This is a back-up information source - it's expected that researchers will generally refer to digitised versions of this document.
