Description

Log of instrument deployments and significant events during the EN524 cruise on R/V Endeavor from 5/19/2013 to 5/22/2013.

Methods & Sampling

Dataset acquisition description

The science party used the R2R event logger (DreamPlug version Release 2.1.16 compiled on May 3 2013 at 14:58:12) to record instrument deployments. The original event log and other underway data submitted by the vessel operator will be available from the NSF R2R cruise catalog: http://www.rvdata.us/catalog/EN524

The final event was entered by the marine technician at the end of the cruise to note when the science seawater flow-through system was stopped, the SBE21 thermosalinograph (TSG) logging was stopped (at around 13:57 UTC), and the system was flushed with fresh water.

Data Processing Description

Dataset Processing Description

depth_w and depth_instr_max values were added by Chief Scientist post-cruise.

BCO-DMO made the following modifcations:
- Modified parameter names;
- 'NaN' and blanks were replaced with 'nd' to indicate no data;
- lat and lon formatted to 4 decimal places;
- Separated the original date-time parameter into month_utc, day_utc, year, and time_utc columns;
- Removed trailing '.001' from all event numbers;
- Removed testing events logged prior to the start of the cruise;
- Added 'sci_event' column, containing the science party's event numbers as recorded in the 'comment' column.
