TITLE: NOAA R/V Ron Brown nutrients AUTHOR(S): Andrew J. Hind ajhind@googlmail.com Patricia A. Matrai pmatrai@bigelow.org Bigelow Laboratory for Ocean Sciences 180 McKown Point W. Boothbay Harbor, ME 04575 USA Phone 207 633 9600; Fax 207 633 9641 1.0 DATA SET OVERVIEW: Discrete measurements of nutrients in seawater. Silicate, phosphate, nitrite and nitrate were measured. Data was collected during Legs 1 and 2 of the VOCALS cruise Time period covered by the data: 23-Oct-2008 to 29-Nov-2008 Platform: Ronald H. Brown Location: mobile 2.0 INSTRUMENT DESCRIPTION: Samples were analysed by the MSI Nutrient Lab at the Marine Science Institute, UC Santa Barbara using the standard methods of Parsons et al. (1984). 3.0 DATA COLLECTION AND PROCESSING: Seawater samples were either taken from Niskin bottles on the CTD rosette or from the ship's non-toxic supply (UW) fed from an inlet at approximately 5 metres below the sea surface. Sampling stations of the two types were sequentially numbered (UW1, UW2, UW3; CTD1, CTD2 CTD3 etc.). The samples were frozen immediately and stored at -20°C. 4.0 DATA FORMAT: Column delimited ASCII Headers YYYYMMDDHHmm Cruise leg Latitude Longitude Station Depth Phosphate Silicate Nitrite Nitrate UTC Degrees N, digital Degrees E, digital meters Micromolar Micromolar Micromolar Micromolar Date of data version: 14-Feb-2011 5.0 DATA REMARKS: REMARKS = These data can be considered final REMARKS = Data point Date/Time provided in UTC REMARKS = Missing data = NaN 6.0 REFERENCES: Parsons, T.R., Maita, Y. and Lalli, C.M., 1984.
