Methods and Sampling: <p><strong>Study area: </strong>The main field study was conducted in a coral reef offshore from the Richard Gump South Pacific Research Station located next to Cook's Bay on the northern shore of Mo'orea, French Polynesia. <span style="font-family:arial,sans-serif">Research was conducted by small boat in a shallow-water coral reef and offshore Pacific Ocean. </span>See Figure 1 in Xue et al. 2022 (under review) for the geographic locations of French Polynesia, the island of Mo'orea, and the schematic description of the reef structure and the reef-ocean transect sampling locations.<br />
<br />
<strong>Sample collection and storage: </strong>Water samples were collected from the near sea surface using precleaned polypropylene bottles from repeated sampling trips to six hydrographic stations along a reef-ocean transect. To collect samples for dissolved concentrations, the unfiltered samples were gravity filtered through a precombusted GF/F filter into precleaned 20 milliliter (mL) scintillation vials following the procedure of small-volume drip filtration (Kiene and Slezak 2006). Paired with each dissolved sample, another set of samples was also collected for the measurement of total concentrations by transferring 15 mL of unfiltered seawater into 20 milliliter (mL) scintillation vials. All samples were microwaved to boiling and allowed to cool to room temperature followed by bubbling using high-purity nitrogen and acidification with 150 microliters of Ultrex-grade HCl. Each sample was collected in duplicate and was stored at room temperature in the dark until analyses were conducted in the home laboratory in Syracuse, New York.<br />
<br />
<strong>Acrylate and organosulfur quantification:</strong> Acrylate concentrations were determined using a pre-column derivatization HPLC method (Xue and Kieber 2021). For derivatization, 300 microliter (µL) thiosalicylic acid (20 mM) reagent was added into a 5 mL precleaned borosilicate vial containing 3 mL of a standard or seawater sample. The pH in each vial was adjusted to 4.0. Then each vial was tightly screw-capped and incubated at 90 degrees Celsius in a water bath for 6 hours. After cooling to room temperature, each derivatized sample was filtered using a 0.2 µm Nylon syringe filter followed by injection of 1 mL sample into a Shimadzu reverse-phase HPLC with UV absorbance detection at 257 nanometers (nm). To measure concentrations of DMSP and DMSO, both compounds were first converted to DMS. To convert DMSP or DMSO to DMS, 200 µL 5 M NaOH or 20% TiCl3 was added to 1 mL of a standard or seawater sample in a precleaned borosilicate serum vial, which was immediately capped and sealed followed by incubation.&nbsp; Incubation for DMSP was overnight at room temperature, while incubation for DMSO was at 55 degrees C for 1 hour. The produced DMS was analyzed using a cryogenic purge-and-trap system and a Shimadzu GC-14A with a flame photometric detector (Kinsey et al., 2016).<br />
<br />
<strong>Chlorophyll a (Chl a):</strong> 250 ml of seawater was filtered through a 25 millimeter (mm) diameter GF/C glass fiber filter that was subsequently stored frozen. The fluorescence of the extracts was measured with a calibrated Turner designs fluorometer</p>
<p><strong>Notes:</strong> Concentrations (column C-H) in dissolved or unfiltered (total) samples are given in units of nanomole/L with subscripts d and t indicating dissolved and total concentrations, respectively.</p>

United States Surface Ocean Lower Atmosphere Study
The Surface Ocean Lower Atmosphere Study (SOLAS) program is designed to enable researchers from different disciplines to interact and investigate the multitude of processes and interactions between the coupled ocean and atmosphere.
Oceanographers and atmospheric scientists are working together to improve understanding of the fate, transport, and feedbacks of climate relevant compounds, and also weather and hazards that are affected by processes at the surface ocean.
Oceanographers and atmospheric scientists are working together to improve understanding of the fate, transport, and feedbacks of climate relevant compounds.
Physical, chemical, and biological research near the ocean-atmosphere interface must be performed in synergy to extend our current knowledge to adequately understand and forecast changes on short and long time frames and over local and global spatial scales.
The findings obtained from SOLAS are used to improve knowledge at process scale that will lead to better quantification of fluxes of climate relevant compounds such as CO2, sulfur and nitrogen compounds, hydrocarbons and halocarbons, as well as dust, energy and momentum. This activity facilitates a fundamental understanding to assist the societal needs for climate change, environmental health, weather prediction, and national security.
The US SOLAS program is a component of the International SOLAS program where collaborations are forged with investigators around the world to examine SOLAS issues ubiquitous to the world's oceans and atmosphere.

Photolysis and Photoproduction of Acrylate in Seawater and their Impact on the Marine Organosulfur Cycle
https://mooreareefresearch.wordpress.com/
Photolysis and Photoproduction of Acrylate in Seawater and their Impact on the Marine Organosulfur Cycle
<p>NSF Award Abstract:</p>
<p>This project would investigate the marine chemistry of the compound acrylate. Acrylate is a mostly overlooked by-product of a very well-studied process through which a compound known as DMSP (dimethylsulfoniopropionate), a compound produced by phytoplankton, is converted to the gas dimethylsulfide (known as DMS). This process is an important part of understanding the marine cycling of sulfur, and DMS plays a role in cloud formation and climate. Thus, these aspects of the conversion of DMSP to DMS have received considerable attention. On the other hand, very little is known about acrylate concentrations, fluxes, or impacts in the oceans, even though it is produced during the conversion of DMSP to DMS. Acrylate concentrations and fluxes should at times be substantial, especially in shallow-water coral reefs or during blooms of DMSP-rich phytoplankton that are common throughout the world's oceans and often harmful or toxic. It is likely that acrylate is a reactive form of marine organic matter that significantly impacts the carbon cycle and ecology of the upper ocean. This project will foster research and educational opportunities for undergraduates and one graduate student through several avenues including field work with international collaborators, attendance at national and local meetings, mentoring, preparing for and delivering college-level lectures, and presentations made to the general public at forums such as Syracuse's Milton J. Rubenstein Museum of Science. Results will be disseminated through peer-reviewed publications, media communications, web-based data bases, and presentations at scientific meetings, public forums and in the classroom.</p>
<p>A three-year project is proposed to study the effect of sunlight on the formation and loss of acrylate in seawater, to model these processes in the water column, and to determine if photoproduction and photolysis are important pathways in the marine acrylate cycle in a shallow-water coral reef. Four objectives are planned to carry out this research: (1) synthesize radiocarbon-labeled DMSP as a source of radiocarbon-labeled acrylate for photolysis and uptake studies; (2) conduct laboratory experiments using a solar simulator to study the photolysis and photoproduction of acrylate in water and seawater under varying conditions (e.g., pH, temperature, oxygen concentration); (3) determine temperature and wavelength-dependent quantum yields for acrylate photolysis and acrylate photoproduction in seawater using a monochromatic irradiation system; and (4) conduct a field study at the Richard Gump Research Station to determine rates of photolysis, photoproduction and microbial consumption of acrylate in a shallow-water coral reef.</p>

PI Supplied Instrument Name: Shimadzu FPD-14 flame photometric detector PI Supplied Instrument Description:DMS was analyzed using a cryogenic purge-and-trap system and a Shimadzu GC-14A with FPD-14 flame photometric detector Instrument Name: flame photometric detector Instrument Short Name:FPD Instrument Description: The determination of sulfur or phosphorus containing compounds is the job of the flame photometric detector (FPD). This device uses the chemiluminescent reactions of these compounds in a hydrogen/air flame as a source of analytical information that is relatively specific for substances containing these two kinds of atoms. The emitting species for sulfur compounds is excited S2. The lambda max for emission of excited S2 is approximately 394 nm. The emitter for phosphorus compounds in the flame is excited HPO (lambda max = doublet 510-526 nm). In order to selectively detect one or the other family of compounds as it elutes from the GC column, an interference filter is used between the flame and the photomultiplier tube (PMT) to isolate the appropriate emission band. The drawback here being that the filter must be exchanged between chromatographic runs if the other family of compounds is to be detected.
