Dataset description
Nutrient concentrations and chlorophyll from bottle samples
collected during CTD-Niskin and Trace-metal clean rosette casts
Acquisition description
dates: 21 January 2002 to 21 February 2002 (20020121-20020221)
location: N: -52.3853 S: -66.6115 W: -175.2212 E: -166.9392
project/cruise: SOFeX/MV
PI note: All of these samples were run at sea and data are considered preliminary.
Processing description
Change history:
070501: downloaded original data (MelvilleStationDataNuts.xls) from SOFeX project data web site.
data prepared by Dave DuBois (OCB DMO, WHOI)
080814: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
PI note: All of these samples were run at sea and data are considered preliminary.
OCB DMO Note: 'CRM' and 'TM' type casts were reported in one worksheet called 'Total'. Data are
presented as sorted in the contributed Excel file, with records sorted first by
cast type (CRM or TM) and then by time. Date, time and position are from the
original data file and not the cruise event log. The 'bot' parameter (bottle number)
could be used as a proxy for depth, or used to retrieve depth data from the SIO_bottle
data object.
The latitude in the original Excel file for station 7 CTD cast 19 was reported as
a different value for each bottle sample. Those values ranged from -0.0470 to 0.4720.
The DMO replaced those values with a single latitude from the cruise event log.
