title: Marine carbon dynamics in a coral reef ecosystem of Southern Taiwan

description: This dataset contains data collected during four seasons: spring (March
 31, 2011), summer (July 5, 2011), autumn (October 20, 2011), and winter
 (January 22, 2013), in the area between Nanwan Bay's two capes, Cape
 Moubitou and Cape Oluanpi. from a total of 17 stations described in the
 paper: “P.-J. Meng, C.-M. Chang, H.-T. Hsieh, A. B. Mayfield, and C.-C.
 Chen (2023). The impact of coral reef ecosystems and upwelling events on
 the marine carbon dynamics of Southern Taiwan, Ocean Science
 (submitted)". The main results of this study included thirteen
 figures as described in the paper, and please refer to it for further
 details.
description: 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.
description: The README file contains an
 explanation of each of the variables in the dataset and its measurement
 units. Information on how the measurements were done can be found in the
 associated manuscript referenced above.
