Description

 PI:              Dennis McGillicuddy and Nick Bates
 of:              WHOI and BBSR
 dataset:         multi-cruise sampling event log
 dates:           12 June 2004 to 03 July 2004  (20040612-20040703)
 location:        N: 37.934  S: 28.641  W: -68.703  E: -58.754
 project/cruise:  EDDIES 2004 Survey 1 OC404-1 and Transect 1 WB0409
 platform:        R/V OCEANUS and R/V WEATHERBIRD II
 
 
 Methodology: processing notes are available
 
 Change history:
   051213: create merged cruise log from OC404-1 and WB0409 CTD event logs
   060313: add date and time fields (cchandler, OCB DMO)
   070227: add all sampling events from complete event log created and 
           contributed by Courtney Ewart (UCSB); (added by cchandler)
 
 Related information:
   070227: Courtney Ewart (UCSB) contributed a merged CTD map for OC404-1 
           and WB0409 that may help to determine relative CTD station locations  
           (PDF file of 3 maps)
 
 DMO note:  The WB0409 cruise is also called EDDIES Transect #1 or EDT1
     (EDDIES Transects 1 and 2 were done in 2004, 3 and 4 in 2005)
     The dist_EC (distance from eddy center, ADCP eddy center trajectories) 
was calculated by Valery Kosnyrev (WHOI).

Data Processing Description

EDDIES 2004 cruises: Survey 1 OCEANUS 404-1 and Transect 1 WB0409
event_log_E1 data processing notes

PI: Dennis McGillicuddy (WHOI) and Nick Bates (BBSR)

27 February 2007: Prepared for OCB data system by Cyndy Chandler, OCB DMO (MCG Dept, WHOI)
from a processing notes file contributed by Courtney Ewart (UCSB).

The merged cruise event log of all recorded sampling events aboard two coordinated EDDIES cruises in 2004 was created and contributed by Courtney Ewart (UCSB) in August 2006.

The merged event log combines data from:
OC and WB CTD cast sheets
WHOI XBT logs and combined CTD station logs (OCB DMO, WHOI)
Thorium pump cast logs contributed by Steve Pike (WHOI)
Optics and BBOP Metadata from Dave Siegel (UCSB)
and ADCP eddy center trajectories calculated by Valery V. Kosnyrev (WHOI)
Information for the sediment traps could not be located.

Explanation of sampling_type descriptor codes

EC	Location of eddy center each day based on ADCP trajectory (V. Kosnyrev). Time was set to 0000 to generate a unique event #, and does not therefore represent GMT 0000.
BBOP	WB chl samples taken for BBOP (1, 20, 40, 60m)
CTD Profile	No bottles fired. CTD depth profile only.
Go-flo	Production array deployment
CTD	Niskin bottles fired and sampled
LP/Rad	Light probe/Radiometer
MOC	Mocness tow
ST	Surface tow
Wire	unknown sampling event type

NOTE: "Rad" and 'LP" are same event type (radiometer) but "OC404-4 event log" info for LP does not match Siegel "Optics Metadata" xls file, so have included both an LP and Rad category here. "LP" events can be eliminated if "Rad" events from optics meta data are correct since "Rad" metadata seems more complete than "LP" metadata.
