Description

These scientific sampling event logs from the 2011 LatMix project cruises include a record of all sampling events from the cruises. Some of the instrumentation is described in the Oceanus ship operations report.

Sampling gear included: Acrobat; ADCP150 (Acoustic Doppler Current Profiler 150); calFluorometer; CTD911 (SeaBird 911plus CTD); dyeinjectionSled; Echosounder12 (12 KHz Knutsen); EM-APEX; gatewayBuoy; Glider; Hammerhead (towed profiler); lagrangianFloat; Navigation; osuMVP; Other (miscellaneous events); profileAOP; profileIOP; Ship (ship events); svpdDrifter; tREMUS (AUV); Triaxus (towed profiler); umassDrogue and uvicMVP.

Methods & Sampling

The event logs from the 2011 LatMix project cruises were created using version 1 of the Rolling Deck to Repository (R2R) event log application (ELOG with cruise-specific custom configuration files). Each cruise used a separate installation of ELOG with a custom configuration file. The ELOG configuration were designed to be compatible so the logs could be combined after the cruise. The three logs can be combined and then sorted on event number to list all LatMix events in chronological order regardless of vessel.

Data Processing Description

Minimal post-cruise processing for the event logs was done by Cyndy Chandler (BCO-DMO). Duplicate event numbers were adjusted so all event numbers are unique (.001 incemented to .002 for a few events). Text was modified in a few free text comment fields to make very long comments shorter and some comments that had been entered in the station number column were moved to the Comment field.
