Methods
Temperature and salinity data were collected using an Idronaut Ocean Seven 304 CTD calibrated against an International Association for the Physical Sciences of the Ocean seawater standard. Water samples were collected using Niskin bottles with Teflon-coated inner walls. Seawater at each station was taken at two to five depths at intervals of 3 to 25 m within or less than the 50 m of water column depth; extra samples at 65, 80 and/or 100 m water depth were taken for stations with depth within 100 m water column depth. Water samples collected were immediately analyzed for dissolved oxygen (DO) using YSI 52 and YSI 5905 BOD electrodes. Other water samples were divided into different sample bottles for additional analyses. One 300-mL amber bottle was pre-inoculated with 0.2 mL of mercuric chloride to suppress biological activity that could affect total alkalinity (TA) and other carbonate system parameters. The analyzed methods for each variable can be found in the paper. The data has been processed by a linear regression analysis using “SigmaStat” to produce a manuscript accepted for publication in Ocean Science.
