 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).

DMO note2: When mapping specifically OC404-4, WB0413 points will appear in the same map and vice versa. This is because this dataset is a combined eventlog. - mda+dld

EDDIES 2004 cruises: Survey 2 OCEANUS 404-4 and Transect 2 WB0413
event_log_E2 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 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.

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.

1c:T17fe,The original title of this project from the NSF award is: Collaborative Research: Impacts of Eddies and Mixing on Plankton Community Structure and Biogeochemical Cycling in the Sargasso Sea". Prior results have documented eddy-driven transport of nutrients into the euphotic zone and the associated accumulation of chlorophyll. However, several key aspects of mesoscale upwelling events remain unresolved by the extant database, including: (1) phytoplankton physiological response, (2) changes in community structure, (3) impact on export out of the euphotic zone, (4) rates of mixing between the surface mixed layer and the base of the euphotic zone, and (5) implications for biogeochemistry and differential cycling of carbon and associated bioactive elements. This leads to the following hypotheses concerning the complex, non-linear biological regulation of elemental cycling in the ocean: H1: Eddy-induced upwelling, in combination with diapycnal mixing in the upper ocean, introduces new nutrients into the euphotic zone. H2: The increase in inorganic nutrients stimulates a physiological response within the phytoplankton community. H3: Differing physiological responses of the various species bring about a shift in community structure. H4: Changes in community structure lead to increases in export from, and changes in biogeochemical cycling within, the upper ocean. Publications Andrews, J.E., Hartin, C., and Buesseler, K.O..
