Data Object event_log_2004-2
PI: Dennis McGillicuddy and Nick Bates of: WHOI and BBSR dataset: multi-cruise sampling event log dates: 25 July 2004 to 20 August 2004 (20040725-20040820) location: N: 32.499 S: 29.958 W: -66.605 E: -59.450 project/cruise: EDDIES 2004 Survey 2 OC404-4 and Transect 2 WB0413 platform: R/V OCEANUS and R/V WEATHERBIRD II Methodology: processing notes are available Change history: 051220: create merged cruise log from OC404-4 and WB0413 CTD event logs 060310: 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) DMO note: The WB0413 cruise is also called EDDIES Transect #2 or EDT2 (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).
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 December 2006. A 12/15/2006
DJM note states that "Updated distance from eddy center column for WBII CTD stations 16-23.
Used estimated EC positions based on extrapolation of trajectory-- no ADCP fixes were available
because Oceanus was to the east sampling another eddy."

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.
| 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.
