Title: Water chemistry at coral reef sites in Timor-Leste from discrete surface and bottom water samples collected in 2013 and 2014
Short Name: Timor: Water Chemistry
Status: Completed
Publication Date: 2017
Abstract:

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.

Laboratory experiments reveal calcification rates of crustose coralline algae (CCA) are strongly correlated to seawater aragonite saturation state. Predictions of reduced coral calcification rates, due to ocean acidification, suggest that coral reef communities will undergo ecological phase shifts as calcifying organisms are negatively impacted by changing seawater chemistry. These water chemistry data for Timor-Leste, along with other data collected at the climate survey sites (water temperature, calcification rates, invertebrate biodiversity, and benthic cover, all archived separately), can be used to help scientists assess and understand how Timor-Leste's coral reefs are responding to ocean acidification.

The water chemistry data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive.

Purpose:

In 2011, NOAA and the United States Agency for International Development (USAID) Timor-Leste Mission formed a 5-year bi-lateral partnership agreement from 2012 to 2016, in support of the Government of Timor-Leste—particularly the Ministry of Agriculture and Fisheries (MAF)—by addressing significant information gaps in their nearshore marine ecosystems. Specifically, MAF asked NOAA to address the following questions:

1.Where are the nearshore marine resources?

2.What are the nearshore marine resources?

3.How are they changing over time and what threats are potentially causing these changes?

4.What approaches are needed to manage and conserve the nearshore marine resources?

With financial support from USAID and in-kind support from the NOAA Coral Reef Conservation Program (CRCP), the NOAA Coral Reef Ecosystem Program (CREP) conducted baseline ecosystem assessment surveys to inform ecosystem-based management planning in Timor-Leste. The primary activities conducted by NOAA to answer these questions included:

1.satellite mapping of nearshore habitats,

2.conducting coral reef ecosystem assessments,

3.establishing ecological baselines for climate change, and

4.building management capacity by developing a spatial data framework

The water chemistry data described herein resulted from the third activity to establish ecological baselines for climate change.

Supplemental Information:

As the survey methods described and used herein are also implemented as part of the NOAA Pacific Reef Assessment and Monitoring Program (Pacific RAMP)—an ecosystem-scale interdisciplinary coral reef monitoring program—the data from Timor-Leste are directly comparable to and informed by data collected by NOAA-CREP throughout the U.S. Pacific Islands and Territories. Furthermore, the methods used for establishing ecological baselines for climate change in Timor-Leste (Chapter 4) are being adopted and implemented at 21 sites across eight member states of the Intergovernmental Oceanographic Commission within the Western Pacific (WESTPAC) region. These data provide a foundation for comparing the ecological baselines under current and future stresses associated with climate change in the Coral Triangle region.

Technical Environment

Description:

Water Sample Data: Microsoft Access 2010

Data Quality

Accuracy:

Water samples: Accuracy of laboratory analysis is explained in detail in Dickson et al (2007).

Comparability:

Since the carbonate system can vary on a diurnal scale and not all samples are taken at the exact same time of day, considering the time a sample was taken may be important for some analyses. However, because all samples are taken between 8:00 AM and 4:00 PM, variation due to diurnal change is expected to be small.

Completeness Report:

Water chemistry data is not provided for all sites where water samples were collected. While processing water samples or during laboratory analysis, any samples deemed unsuitable/poor quality were thrown out.

Conceptual Consistency:

The same methods of data collection were used at each surveyed site within a survey year, though, there were minor differences in survey protocol between samples collected in 2013 and 2014 (see lineage/methodology section). The processed/analyzed data are very consistent, sample collection and processing protocols are adhered to very rigorously, both in the field and in the lab.

Quality Control Procedures Employed:

PMEL conducts quality assurance and quality control on their analyses; the precision and accuracy of DIC analyses are on the order of ± 0.05% and TA analyses are on the order of ± 0.1% in a laboratory setting.

Data quality flags are provided by NOAA Pacific Marine Environmental Laboratory (PMEL) and included in the dataset. These flags indicate if something went wrong with the analytical equipment or with the processing of the samples. PMEL uses the World Ocean Circulation Experiment (WOCE) data quality flag system, where '2's correspond to good values, '3's to questionable data, and '4's to bad data. Most water samples collected by the NOAA Coral Reef Ecosystem Program (CREP) and analyzed by PMEL in this dataset received a '2' data quality flag and the remainder were flagged as questionable ('3').

Data Management

Have Resources for Management of these Data Been Identified?: Yes
Approximate Percentage of Budget for these Data Devoted to Data Management: Unknown
Do these Data Comply with the Data Access Directive?: Yes
Is Access to the Data Limited Based on an Approved Waiver?: No
Approximate Delay Between Data Collection and Dissemination: Unknown
Actual or Planned Long-Term Data Archive Location: NCEI-MD

How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

The data resides in an MS Access database, which is maintained and regularly backed up by PIFSC ITS.

Lineage

Lineage Statement:

NOAA Coral Reef Ecosystem Program (CREP) assembles carbonate chemistry information from discrete seawater samples analyzed for two parameters: 1) Dissolved Inorganic Carbon (DIC), which in some literature is defined as Total Carbon (CT), and 2) Total Alkalinity (TA or AT).

All carbonate system collection and measurement methodologies follow the protocols accepted by the greater scientific community and outlined in Dickson et al. (2007)

Process Steps

Process Step 1

CC ID: 569637
Description:

At each Climate Monitoring site, 1 discrete near reef seawater sample (recovered at ~15-m depth) and 1 surface seawater sample (recovered at ~1-m depth) were collected using 5-L Niskin bottles. In 2013, a third seawater sample was collected ~1-km offshore from each site (recovered at ~1-m depth). Each time a water sample was collected, it was divided into: (1) a 500-mL glass bottle and preserved with mercuric chloride (for dissolved inorganic carbon [DIC] and total alkalinity [TA] analysis) and (2) a 250-mL HDPE plastic bottle (for salinity analysis). During both 2013 and 2014 field efforts, 1 in 4 water sample collections were replicated to ensure analytical reproducibility.

Discrete water samples are collected according to the protocol established by the NOAA Pacific Marine Environmental Laboratory (PMEL).
