The CTD (SBE-25) was equipped with 6 4L niskin bottles and was used to measure temperature and salinity. Niskins were used to collect water samples for carbonate chemistry (i.e., DIC and TA), oxygen, and nutrients. Water samples for DIC and TA were collected according to the methods in Dickson et al. (2007), and analyzed at TAMU using a VINDTA 3C. Certified Reference Materials (CRMs) were provided by A. Dickson at Scripps Institute of Oceanography (Dickson et al. 2007) and were used to calibrate for TA and DIC. The reproducibility of these samples was 1.43 \u00b1 1.07 \u03bcmol kg-1 for TA and 2.64 \u00b1 1.24 \u03bcmol kg-1 for DIC. Dissolved oxygen (DO) was measured using Winkler titrations. After collecting the water from the Niskin into flasks, aliquots of manganese chloride and sodium hydroxide-sodium iodide were added. The titration was performed directly after water collection using sodium thiosulfate; Winkler titration was performed with an amperometric dead-stop endpoint determination with a double platinum electrode. Nutrient samples (nitrate, nitrite, ammonium, phosphate, and silicate) were collected into polycarbonate flasks after filtration through GF/C 0.7-um pore size filters, frozen, and analyzed ashore using standard World Ocean Circulation Experiment (WOCE) segmented flow methodologies using an Astoria Analyzer (Astoria-Pacific) (Gordon 1994 ).
\nSampling gaps are reported as \"nd\" in the dataset.
This dataset combines the biogeochemical data collected during the Flower Garden Banks Rapid Response Cruise which occurred following the discovery of the localized mortality event.
BCO-DMO Processing:
\n- renamed fields (removed spaces and units);\u00a0
\n- formatted date column to yyyy-mm-dd (was m/d/yy);
\n- corrected year value of 2006 to 2016 (in row 128);
\n- added ISO_DateTime column
\n- replaced \"nan\" with \"nd\" (no data)
