Water chemistry at coral reef sites in Timor-Leste from discrete surface and bottom water samples collected in 2013 and 2014

Description

The water chemistry data described here are from discrete water samples collected by the NOAA Coral Reef Ecosystem Program (CREP) in 2013 and 2014 to assess the seawater carbonate systems primarily at fixed climate survey sites located in coral reef habitats in Timor-Leste. Climate sites were established by CREP to establish ecological baselines for climate change by measuring multiple features of the coral reef environment (in addition to the data described herein) over time. Water chemistry data for both 2013 and 2014 is only available for a subset of the established climate survey sites (5 of the 8 sites). In 2013, water samples were collected from a few random sites in addition to the samples collected at the climate survey sites. SCUBA divers collected two discrete water samples from each site; one at the reef and one at the surface directly above the reef. In 2013 only, surface water samples were also collected ~1 km offshore from the survey site. The samples were processed by CREP and sent to NOAA Pacific Marine Environmental Laboratory (PMEL) to be analyzed for total alkalinity (TA) and dissolved inorganic carbon (DIC). From these constituents, alongside temperature, salinity, and depth data, other parameters of the seawater carbonate system were calculated, including pH, partial pressure of carbon dioxide, and aragonite saturation state. The water chemistry data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive.
