Description

Scientific Sampling Event Log for KN199-04 (2010 GEOTRACES cruise). Station numbers, Events, Dates/Times, Lat/Lons and Event descriptions are provided for each station.

NOTE: No event log maintained for KN199-05

Methods & Sampling

Generated aboard vessel by science party.

Event Description Codes:
nd = unknown/not entered
GT-C = GEOTRACES carousel
30-ODF = 30L Niskin Rosette
GeoF = Geos fish
RaPUW = Radium UW pump
MITv2 = MIT-vane
UAFv = UAF-vane
KnoR = Knorr rosette
MastUp = NASA solar reference mast UP
MastDown = NASA solar reference mast DOWN
McL-Ros = McLane pump rosette
McL-Prof = McLane pump profile
Aeros = Aerosol sampler
AOP = Apparent Optical Properties cast
NASAsurf = NASA surface pump water sample
NEMO = NEMO Float Deployment
Ra/Th/Pig = Ra/Th/Pigment Niskin Cast

Codes for Samples Taken:
nd = unknown/not recorded
diss = dissolved samples
diss+part = dissolved and particulate samples
unfilt = unfiltered seawater
filter = filter for particulates
none = none

Data Processing Description

BCO-DMO Processing Notes
- Generated from original .xlsx file "KN199-4 event log sheet.xlsx" contributed by Bill Jenkins
- Lat/Lon converted from degs, decimal minutes to decimal degrees
- Lon values signed negative for West
- Date reformatted to YYYYMMDD
- Time reformatted to HHMM
- "nd" (no data) value inserted in blank cells
- "n/a" replaced with "nd"
- Commas in text fields converted to semicolons
- Parameter names modified to conform to BCO-DMO convention<
- End dates for events 2003, 2004, 2005, 2006, 2007 changed from 2010/10/16 to 2010/10/15 (25July2011/srg)
