Description

The science party maintained a digital event log, recording all instrument deployments and significant events during the BaRFlux cruises.

NOTE: These data are preliminary; position corrections have not been made when needed (refer to the 'comment' column).

Methods & Sampling

Dataset acquisition description

EN501: The science party used an Excel spreadsheet to record all instrument deployments during the BaRFlux 1 cruise. This version of the event log was posted following the initial post-cruise review by the science party.

EN502, AE1211, EN513, and EN520: For the BaRFlux 2, 3, 4, and 5 cruises, the scientific sampling event log was created using the Rolling Deck to Repository (R2R) event log application (ELOG with cruise-specific custom configuration files). The log includes a record of all scientific sampling events from the cruise. In addition to event identification numbers unique for the cruise, the scientific sampling event log includes date and time (GMT), position (latitude and longitude), station and cast identifier as appropriate to the sampling event, sampling instrument name (e.g. CTD, TM, MOC10), name of person responsible for the sampling event, and a comment field to record additional information. See more information about the R2R event log.

Deployment-specific acquisition description

On the 5th BaRFlux cruise, EN520, the scientific sampling event log was created using the Rolling Deck to Repository (R2R) event log application. See more information about the R2R event log.

Data Processing Description

Dataset Processing Description

BCO-DMO made the following modifcations:
- Comments have been added in the 'comment' column to draw attention to those events that need time/position correction.
- All original column names were converted to lowercase;
- 'NaN' and blanks were replaced with 'nd' to indicate no data;
- Events logged as part of testing the event logger application have been removed from the data display;
- lat and lon formatted to 5 decimal places for all cruises;
- The original 'dateTimeUTC' column was separated into two columns: date_utc and time_utc;
- 02 April 2013: The corrections below were made after correspondence with the project PI:
(1) Removed event 20120819.2233.001 from EN513. This was a duplicate entry that should have been deleted.
(2) Changed station of event 20120819.2210.001 (EN513) from M+2 to M+1.
(3) Changed cast # of event 20120823.0319.001 (EN513) from 'nd' to 7.
(4) Added events 20120507.1530 through 20120508.0842 from event log provided by Cyndy Lee to BCO-DMO on 18 Oct 2012.
