Dissolved inorganic carbon, total alkalinity, pH and other variables collected from surface discrete measurements using Coulometer, alkalinity titrator and other instruments from Timor-Leste from 2013-06-06 to 2014-10-09 (NCEI Accession 0168915)

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.
