Description

Scientific sampling event logs from Gulf of Maine Krill project cruises on R/V Endeavor (EN484 and EN487).

Methods & Sampling

Dataset acquisition description

These scientific sampling event logs from the Gulf of Maine Krill project cruises were created using an early implementation of 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.

Deployment-specific acquisition description

This scientific sampling event log from the EN487 Krill cruise was created using an early implementation of the R2R event log application (eLog with custom configuration file). It includes a record of all scientific sampling events from the cruise.

Data Processing Description

Dataset Processing Description

Post-cruise processing for 2010 cruise logs was done by Tobias Work (an EN484 cruise participant) and Cyndy Chandler, both members of BCO-DMO. Missing events were added, times were corrected and missing latitude and longitude were added using the along track data as a source. Duplicate event numbers were modified so all event numbers are unique. Text was modified in the free text comment field to make the comments shorter. The R2R event number and original date and time in UTC are not displayed (those columns have been hidden), but could be added if desired.

Deployment-specific processing description

<p>BCO-DMO did some post-cruise QC work: renumbered a few duplicate event ID numbers (and changed local time to match) these were most often the End/Start of a Transect, and one event ID of the pair was adjusted by one minute to make it unique; replace comma with semi-colon in comment field; replace Ship instrument with Cruise or Transect and make all Action entries either Start | End (per PI P. Wiebe request); verified that all instrument events had start/end pairs and all Transect numbers entered where appropriate (some had been NaN) for all events between the Start and End of a Transect.</p>
