K-Axis Science Event Log with derived latitude and longitude from underway data

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 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 data
