        abstract:  This dataset contains carbonate chemistry data from samples collected across Timor-Leste as part of the USAID funded US Coral Triangle Initiative from 2013-06-06 to 2014-10-09. The project monitors changes to coral reef carbonate chemistry over time at coral reef sites within Timor-Leste by quantifying key chemical parameters that are expected to change with ocean acidification. Incorporating an interdisciplinary approach, this project collects, processes, analyzes, and stewards dissolved inorganic carbon (DIC) and total alkalinity (TA) water sample data to document seawater carbonate chemistry at monitoring sites in coral reef areas of Timor-Leste.
        purpose:  This project utilized NOAA’s scientific and capacity building expertise to incorporate considerations of climate change, ocean acidification, and their impacts on biodiversity and fisheries into an Ecosystem Approach to Fisheries Management (EAFM) framework. Building on existing expertise across the Pacific Islands and Coral Triangle, this project worked with local governments, communities, and NGO’s to build local science capacity through establishment of robust observing capabilities and hands-on training to initiate collection of sound ecosystem/climate science information that can be utilized toward adaptive EAFM and MPA conservation management strategies.

The SOMMA systems were originally developed by Ken Johnson (Johnson et al.,1985,1987,1993; Johnson,1992; Wilke et al., 1993) of Brookhaven National Laboratory (BNL).; Detailed sampling and analyzing information: Analyses conducted at NOAA PMEL. Measurements drawn according to procedures in the Guide to Best Practices for Ocean CO2 Measurements (Dickson et al., 2007). Borosilicate bottle were rinsed and filled from bottom, leaving a minimal amount of headspace while making sure no bubbles were introduced. Then 0.2 ml of saturated HgCl2 solution was added, bottles were sealed with glass stoppers lightly covered with Apiezon-L grease, and were stored at room temperature to be sent to PMEL for analysis.; Standardization description: Each coulometer was calibrated by injecting aliquots of pure CO2 (99.999%) by means of an 8-port valve (Wilke et al. 1993) outfitted with two calibrated sample loops of different sizes (~1 mL and ~2 mL). The instruments were each separately calibrated at the beginning of each cell with a minimum of two sets of these gas loop injections.; Standardization frequency: 1) Gas loops were run near the beginning of each cell; 2) CRM’s supplied by Dr. A. Dickson of SIO, were also measured near the beginning; and 3) Duplicate samples were typically run throughout the life of the cell solution.; CRM manufacturer: Andrew Dickson's lab at Scripps Institute of Oceanography; CRM batch number: 124, 143; Preservation method: Saturated Mercuric Chloride (HgCl2) Solution; Preservative volume: 0.2 ml; Preservative correction: The DIC values were corrected for dilution by 0.2 ml of saturated HgCl2 used for sample preservation.

                description:  Parameter or Variable: Total alkalinity; Abbreviation: TALK_UMOL_KG; Unit: micromoles/kg; Observation type: Discrete measurements from samples collected on CTD casts; In-situ / Manipulation / Response variable: in-situ observation; Measured or calculated: Measured; Calculation method and parameters: none; Sampling instrument: Niskin bottle - transferred to Borosilicate bottle; Analyzing instrument: Custom instrument, built at PMEL and modeled after an earlier generation of those made in Dr. Andrew Dickson's laboratory at Scripps Oceanographic Institution.; Type of titration: Two-stage, potentiometric, open-cell titration using coulometrically analyzed hydrochloric acid.; Cell type (open or closed): Open; Curve fitting method: Non-linear least squares; Detailed sampling and analyzing information: Analyses conducted at PMEL. Samples run using remaining water from the same sample bottles used for DIC. Seawater total alkalinity (TA) was measured by acidimetric titration. The specific method used was based upon the open-cell method described by Dickson et al (2003). This method involves first acidifying the sample to reduce the sample pH of just over 3.5 followed by bubbling CO2-free air through the sample to facilitate removal of the CO2 evolved by the acid addition. After removal of the carbonate species from solution, the titration proceeds until a pH of just below 3.0 is attained, and the equivalence point evaluated from titration points in the pH region 3.0–3.5 using a non-linear least squares procedure that corrects for the reactions with sulfate and fluoride ions (Dickson et al. 2003). Titration progress is monitored by measuring the electromotive force (E) of a combination glass-reference electrode. Samples were drawn from the Niskin-type bottles into cleaned 500-ml borosilicate glass bottles using Tygon tubing with silicone ends. Bottles were rinsed three times and filled from the bottom, overflowing half a volume and taking care not to entrain any bubbles. The sample tube was closed off and withdrawn from the sample bottle, creating a 5 ml headspace. Samples were preserved by poisoning with 0.2 ml of a saturated HgCl2 solution. Sample bottles were sealed with glass stoppers lightly coated with Apiezon-L grease, and were stored in an air-conditioned laboratory on the research vessel. Samples were shipped to PMEL following cruise completion, and were stored at room temperature (21-25 °C) for a maximum of 12 hours prior to analysis. Titrations were carried out in water-jacketed, 250-ml beakers. The beakers were kept at 24.0 +/- 0.2 °C with water from a constant temperature bath. Prior to analysis, samples were placed in the water bath to bring them to the same temperature as the reaction beakers. Seawater samples were dispensed into the water-jacketed beaker using a fixed-volume glass syringe. A Metrohm Dosimat 765 was used to deliver acid to the sample beaker in increments of 0.040 ml. The acid titrant used was 0.1 mol/kg HCl prepared in 0.6 mol/kg NaCl background to approximate the ionic strength of seawater (0.7 mol/kg). Instrument control and data acquisition was with custom software developed in Andrew Dickson's laboratory at Scripps Institution of Oceanography and modified by a former employee of the NOAA/PMEL Carbon Group using the National Instruments LabView programming environment. Typical titrations were completed in 10-14 minutes and required 20-24 acid additions to reach a pH of 3.0.; Standardization description: Duplicate samples are run in addition to Certified Reference Material (CRM), supplied by Dr. A. Dickson of UCSD; Standardization frequency: Along with duplicate samples being run throughout, CRMs are run at the beginning and end of each sampling period; CRM manufacturer: Andrew Dickson's lab at Scripps Institute of Oceanography; CRM batch number: 124, 142, 143; Preservation method: Saturated Mercuric Chloride (HgCl2) Solution; Preservative volume: 0.2 ml; Preservative correction: The TA values were corrected for the resulting dilution of the added 0.2 ml of saturated HgCl2 used for sample preservation.; TA blank correction: NA; Uncertainty: +/-0.1%; Quality flag convention: WOCE water sample quality flag; Method reference: -Bates, R.G.

                description:  Parameter or Variable: An identifier for the fixed NCRMP climate site associated with the sample, if any. An OCC_SITEID is a 3-dimensional identifier that describes a location (LATITUDE and LONGITUDE) and depth of a fixed climate site and includes "OCC" prefix, a 3-letter location code (derived from LOCATIONCODE), and a 3-digit site number.
