Abstract

The data provided in this data set are from diel surveys conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD)---formerly the Coral Reef Ecosystem Division---in the Philippines from May 21-31, 2015. The ocean acidification diel suite is an autonomous instrument package that measures diel variability in coral reef seawater carbonate chemistry. These diel suites were deployed on hard-bottom shallow-water (< 15 m) habitats at fixed climate survey sites located within coral reef ecosystems.

The diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, pH, current direction and magnitude, and dissolved oxygen. Seawater samples were also collected for laboratory analyses of dissolved inorganic carbon (DIC) and total alkalinity (TA). Components of the carbonate system--including pH, pCO2 (partial pressure of carbon dioxide), and aragonite saturation state--are calculated from DIC, TA, temperature, salinity and pressure. Each diel suite consisted of: 1 SBE-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 SBE 43 dissolved oxygen sensor co-located with the CTD, and up to 9 Programmable Underwater Collectors (PUCs), each of which collected 1 water sample at 4-hour intervals. Instruments deployed, samples collected, and sample intervals are recorded in the summary file in the data package.

Title: Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites in Batangas, Philippines from May 21-31, 2015
Short Name: Philippines: diel surveys
Status: Completed
Publication Date: 2017
Abstract:

The data provided in this data set are from diel surveys conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD)---formerly the Coral Reef Ecosystem Division---in the Philippines from May 21-31, 2015. The ocean acidification diel suite is an autonomous instrument package that measures diel variability in coral reef seawater carbonate chemistry. These diel suites were deployed on hard-bottom shallow-water (< 15 m) habitats at fixed climate survey sites located within coral reef ecosystems.

The diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, pH, current direction and magnitude, and dissolved oxygen. Seawater samples were also collected for laboratory analyses of dissolved inorganic carbon (DIC) and total alkalinity (TA). Components of the carbonate system--including pH, pCO2 (partial pressure of carbon dioxide), and aragonite saturation state--are calculated from DIC, TA, temperature, salinity and pressure. Each diel suite consisted of: 1 SBE-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 SBE 43 dissolved oxygen sensor co-located with the CTD, and up to 9 Programmable Underwater Collectors (PUCs), each of which collected 1 water sample at 4-hour intervals. Instruments deployed, samples collected, and sample intervals are recorded in the summary file in the data package.

Purpose:

ESD's manual seawater sampling and other field monitoring efforts are limited to daylight hour operations. As a result, these data sets do not capture full 24-hour variability in coral reef physical and chemical environments. The ocean acidification diel suite was developed to increase the temporal resolution and coverage of oceanographic and carbonate chemistry measurements and contextualize daytime sampling within the full diel cycle.

Supplemental Information:

The Ecosystem Sciences Division (ESD) at NOAA Fisheries is conducting in-situ climate monitoring across the U.S. Pacific Islands Region. Climate monitoring provides a comprehensive view of climate change impacts on coral reef ecosystems and helps identify areas of resilience and vulnerability. The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) ecological impacts by collecting data on coral growth rates and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem. This particular dataset for the Philippines is part of a 3-year project ("Climate, Biodiversity and Fisheries in the Coral Triangle: Embracing the E in Ecosystem Approaches to Fisheries Management") implemented by ESD. This project was funded by NOAA's Coral Reef Conservation Program (CRCP) and the U.S. Agency for International Development (USAID) Regional Development Mission Asia (RDMA) as part of the U.S. Coral Triangle Initiative, with additional support from the Coral Triangle Support Partnership and USAID Philippines. The goal of the project was to build on ESD's expertise to provide tools and information about climate change, ocean acidification, and their impacts on biodiversity and fisheries that could inform and be incorporated into an Ecosystem Approach to Fisheries Management (EAFM) for the Philippines. ESD worked with local governments, communities, and NGOs to build science capacity by establishing robust observing capabilities and providing hands-on training to initiate collection of climate science information for the Verde Island Passage in the Philippines that can be used toward adaptive EAFM.

ESD traveled to the Verde Island Passage region of the Philippines in 2012 to deploy moored oceanographic (subsurface temperature recorders [STRs]) and ecological (calcification accretion units [CAUs] and autonomous reef monitoring structures [ARMS]) instrumentation, to collect surface and bottom water samples, and to conduct benthic photo-quadrat surveys, which included the collection of benthic images; in 2013 to collect additional water samples; and again in 2015 to recover the instrumentation and to collect another round of water samples and benthic images and to conduct diel surveys. All activities were conducted by SCUBA divers at five locations in the municipalities of Mabini and Tingloy, including Batong Buhay, Koala Reserve Area, Arthur's Reef, Twin Rocks, and Batalang Bato. At each of the five locations, a shallow and deep survey site was established for a total of 10 survey sites.

Technical Environment

Description:

Raw data are downloaded from the instruments, processed in R, and migrated to the PIFSC Oracle database.

Water sample data is stored in an MS Access database.

Data Quality

Representativeness:

Seawater carbonate chemistry at the benthos is dynamic and driven by physical and biological processes occurring at time scales of minutes to days. The measurements and analyses from this instrument suite is representative of the water column chemistry at the time of measurement, but this highly variable environment allows for a fairly wide distribution of measured values.

Accuracy:

Water samples: accuracy of seawater carbonate chemistry laboratory analysis is explained in detail in Dickson et al (2007), SOP #2: Determination of total dissolved inorganic carbon in sea water, and SOP #3b: Determination of total alkalinity in sea water using an open-cell titration.

Satlantic SeaFET Ocean pH sensor: measurement range: 6.5-9.0 pH; salinity range: 2-40 psu; accuracy: +/- 0.05 pH; precision: better than 0.001 pH; resolution: 0.0001 pH; stability: 0.005 pH/mo

SBE-19plus CTD sensor:

Conductivity - measurement range: 0-9 S/m; accuracy: +/- 0.0005 S/m; stability: 0.0003 S/m per month; resolution: 0.00005 S/m;

Temperature - measurement range: -5-35 deg C; accuracy: +/-0.005 deg C; stability: 0.0002 deg C per month; resolution: 0.0001 deg C;

Pressure - measurement range: 0-600 m; accuracy: +/- 0.1%; stability: +/- 0.1%; resolution: 0.002%

SBE 43 oxygen sensor: Measurement range: 120% surface saturation; accuracy: +/- 2% of saturation; stability: 0.5% per 1000 hours

Nortek Acoustic Doppler Current Profiler 1MHz: Profiling range: 12-25 m; accuracy: +/- 1%

Completeness Measure:

The entire suite of instrumentation is deployed during diel surveys; however, various issues can occur with any one or several of the instruments during the deployment thereby limiting the data recovered.

While PUCs are programmed to collect water on this regular sampling schedule, issues with the pumps can occasionally result in missing samples for some of the time steps.

Field Precision:

Redundant data are collected to ensure accuracy of the methods/instrumentation. pH is captured from the discrete water samples and pH sensor. Pressure is captured by the ADCP and the CTD. Temperature is captured by the pH sensor and the CTD.

Completeness Report:

All analyzed samples and measured values are included. NULL values in the data, where they exist, indicate that the observation/analysis was not conducted for the sample record where it appears.

Conceptual Consistency:

The data are very consistent, sample collection and processing protocols detailed in Dickson et al (2007) are adhered to rigorously, both in the field (SOP #1) and in the laboratory (SOP #2 and #3b).

Quality Control Procedures Employed:

The data is quality controlled by NOAA PIFSC Ecosystem Sciences Division (ESD) personnel after the data is downloaded from the instruments, after it is migrated to the database, and once again when the data are submitted to the NOAA National Centers for Environmental Information.

NOAA Pacific Marine Environmental Laboratory (PMEL) conducts quality assurance and quality control on their seawater analyses according to protocols #2 and #3b in Dickson et al (2007).

Lineage

Lineage Statement:

The ocean acidification diel suite is a collection of instruments deployed by SCUBA divers onto the seafloor that makes autonomous measurements and collects seawater samples. For a typical deployment, the diel suite consists of: 1 Sea Bird Electronics (SBE)-19plus CTD, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 SBE 43 dissolved oxygen sensor, and up to 9 Programmable Underwater Collectors (PUCs), where each PUC collects 1 water sample at a 4-hour interval over a minimum 24-hour period. All instruments are weighted or zip-tied to rubble on the seafloor, or both, to secure the position of the instrumentation for the duration of the deployment.

Process Steps

Process Step 1

CC ID: 566669
Description:

Water samples collected with Programmable Underwater Collectors (PUC)

Developed by Dr. Chris Langdon's laboratory at the University of Miami, PUCs are computerized timers attached to a low-power peristaltic pump. An array of PUCs collects water samples at 4-hour intervals over the course of at least 24-hours, usually starting at 12:00 pm local time on day 1 and ending at 12:00 pm on day 2. While PUCs are programmed to collect water on this regular sampling schedule, issues with the pumps can occasionally result in missing samples for some of the time steps.

Samples are collected underwater in tedlar bags pre-poisoned with mercuric chloride and transferred to glass bottles within a few hours of recovery. Water samples are analyzed for DIC using a coulometer (SOP #2) and for TA using a titrator (SPO #3b) by the NOAA Pacific Marine Environmental Laboratory. Full carbon system chemistry values (including pH, pCO2, and aragonite saturation state) are derived from DIC/TA and salinity/temperature/pressure data from a co-deployed CTD using the R package seacarb. Discrete sample pH data are compared to SeaFET pH data.

Process Step 2

CC ID: 566670
Description:

Acoustic Doppler Current Profiler (ADCP) sensor

The diel suite includes either a side-looking ADCP. ADCP measurements are collected at 10 minute intervals and binned by height above the sensor. Each height bin is represented in the data set as the upper limit of the bin height above the sensor on the seafloor (for example, a 1.4 m bin represents current data collected between 0.4 m and 1.4 m above the ADCP). ADCP data include a blanking region, or a small distance in front of the transducer in which measurements cannot be made, of 0.2-0.4 m. Current data are grouped into 1-m height bins.

Raw data downloaded from the ADCP are processed in R using the oce package. XYZ coordinate data are converted to ENU (east-north-up) coordinate system. Current speed is calculated as the square root of the sum of the squared u and v velocities and direction as the arctan(v/u). Data are trimmed to a maximum height bin for each time step using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides.

Process Step 3

CC ID: 566671
Description:

Conductivity-Temperature-Depth (CTD) sensor

CTD data are collected by a Sea Bird Electronics 19plus v2 SeaCAT every 10 minutes. Data are uploaded as HEX files, converted to CNV using SBE Data Processing Software, and converted to CSV using the 'oce' package in R.

Process Step 4

CC ID: 847045
Description:

SeaFET pH sensor

The SeaFET pH measures in-situ pH using a solid state ISFET sensor with an AgCl external reference electrode. The electrode is conditioned in running seawater up to a week prior to deployment and stored in artificial seawater between deployments. pH data are collected in bursts of 30 measurements every 5 minutes. The SeaFET is co-deployed with a CTD, and temperature and salinity values from the CTD time series are used to correct the raw pH time series. The SeaFET derives pH from both internal and external potentiometric cells, but only external pH is reported. SeaFET pH values are compared to pH values calculated from discrete TA and DIC samples collected at the same time and location.
