Sampling and analytical procedures: From Cao et al. (2020):
Sampling: As part of the Deep Ocean Refractory Carbon (DORC) field campaign aboard the R/V Melville in the Gulf of Alaska (August 4–21, 2013) we performed high-resolution surveys of DOM optical properties, collecting samples from the sea surface down to ~5000 m using a 24 Niskin bottle rosette with a Sea-Bird CTD (conductivity-temperature-depth) sensor. Corresponding hydrographic (depth, T, S) and chemical (nitrate, nitrite, ammonia, silicate, phosphate, oxygen) data were collected for each cast and submitted to BCO-DMO (http://data.bco-dmo.org/jg/serv/BCO/NorthPacifi c_RDOC/CTD_Profiles.brev0) by co-chief scientist (D. Hansell, University of Miami). The DOC data corresponding with the optical measurements were also generated in the Hansell lab. For optical measurements, all labware was acid soaked in 2N HCl overnight with glass bottles subsequently precombusted (450C, 3 h minimum), and rinsed thoroughly with Milli-Q water (MQ; >18.2 MΩ⋅cm; Millipore) that was freshly produced on the ship (within 1 day) prior to sample collection. Seawater was gravity filtered directly from the Niskin bottle via silicon tubing through a pre-cleaned, 0.2 μm Whatman Polycap AS 75 nylon cartridge filter into the glass bottles. Filtered samples were analyzed for optical properties within 4 h after sampling to avoid potential long-term storage artifacts.
Fluorescent measurement of DOM and PARAFAC modeling:
A fluorescent excitation-emission matrix (EEM) spectrum was obtained for each sample with an Aqualog spectrofluorometer (HORIBA Jobin Yvon Inc., NJ, USA) using a 1-cm quartz cell with MQ as the blank. EEM fluorescence intensities were measured by scanning across an excitation range of 240–450 nm (5 nm intervals) and capturing emission spectra over a wavelengths range of 280–500 nm at 3.2 nm intervals. We optimized data quality by determining the integration time for each sample that maximized emission intensity detection at short excitation wavelengths without saturating the CCD at long excitation wavelengths (Gentry-Shields et al., 2013).
CDOM absorption measurement and spectral slope calculations:
CDOM absorption spectra were obtained with filtered samples at room temperature using a single-beam liquid waveguide capillary flow cell (World Precision Instruments Inc., measured at 92.2 cm pathlength), coupled with quartz fiber optic cables to a deuterium-tungsten light source (DT-mini GS) and a MAYA2000 PRO spectrophotometer (Ocean Optics, Inc.). To eliminate contamination from pump tubing, cleaning solutions and samples were pulled slowly through the system using Teflon lines and a peristaltic pump (~0.5 ml/min) located downstream from the waveguide.
The flow cell was cleaned at regular intervals (~every 10 samples) using a rotating valve that sequentially rinsed with a 20:80 vol/vol acetone:water mixture, 2N HCl, and fresh MQ water. In addition, to alleviate the common problem of microbubbles that accumulate on the interior surfaces of the flow cell when analyzing seawater samples, we dissolved bubbles off the cell walls back into degassed MQ supplied through a Liqui-CelTM MM-0.5x1 Series Membrane Contactor (3MTM) attached to an oilless vacuum pump. This was routine after the cleaning sequence and also used when blanks remained high after cleaning or between seawater samples. Removal of microbubbles was confirmed when no measurable change in absorbance was observed due to bubble compression after pressure was applied to the flow cell with MQ using a separate syringe. While this procedure proved excellent for removing attached microbubbles, the internal epoxy used to attach the membranes to the polycarbonate body of the Liqui-CelTM contributed an observable “CDOM-like” absorbance that could not be eliminated through cleaning the cartridge. Consequently, we flushed the system with MQ water after cleaning, degassing, and between samples until no change was observed in the UV portion of the blank spectrum with repeated “re-blanking” of the MAYA2000 signal. This re-blanked MQ reference accounted for instrument drift.

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.

Quantifying the Photochemical Reactivity of Deep Ocean Water

Quantifying the Photochemical Reactivity of Deep Ocean Water
<p><em>NSF award abstract:</em><br />
Because 70% of marine dissolved organic carbon (DOC) is found in the deep ocean, it is important to determine its sources and sinks to understand its role in the global carbon cycle. Unfortunately, the sinks for DOC at depth remain largely unknown; however, limited data has suggested that photochemistry may influence the removal of deep refractory DOC. A scientist from the University of Georgia will use field and laboratory irradiation experiments to quantify the photochemical rates controlling (1) direct loss of DOC and photoproduction of carbon monoxide, a significant product resulting from DOC oxidation, (2) common optical tracers of organic carbon such as colored dissolved organic matter and fluorescent dissolved organic matter fading; and (3) two reactive oxygen species (hydrogen peroxide and superoxide) that reflect the role of oxygen in DOC photochemistry. The study will focus on the north Pacific, where the lowest deep ocean DOC concentrations are found which most likely reflect the presence of an aged and refractory carbon pool. Layered in the top 1000m above this deep DOC is a concentration gradient that will allow comparison of waters with different DOC concentrations, ages and apparent refractivity. Results from the study will be used to quantitatively reevaluate this basic question that now constrains global DOC models: Does photochemistry have a significant role in the removal of the massive amount of refractory DOC that is pooled in the deep sea?</p>
<p>In terms of the broader impacts, based on established links with K-12 teachers, the scientist and his students plan visits to local schools to present their science, as well as have a website entitled "ask the oceanographer" and maintain a live blog during their cruise. Results from this study will be included into class materials dealing with the carbon cycle. One graduate and three undergraduate students would be supported and trained as part of this project. It is anticipated that undergraduate students from historically underrepresented groups would be recruited via the University of Georgia's Summer Undergraduate Research Program.</p>

Data processing:
Fluorescent DOM processing and PARAFAC modeling: Post-processing EEM spectra to correct and calibrate the spectra was conducted following Murphy et al. (2010) and included four steps: (1) manufacturer-provided spectral correction parameters were applied to each EEM, (2) inner filter effects were corrected for sample EEMs following Lakowicz (2013), (3) spectra were normalized to the MQ Raman peak area at an excitation wavelength of 350 nm, and (4) MQ Raman and Rayleigh scatter signals were removed using an interpolation method following protocols developed by Bahram et al. (2006). Fluorescence intensities (FI) are herein reported in Raman Units (RU).
A total of 518 samples were pooled for PARAFAC analysis using the DOMFluor toolbox in MATLAB (Stedmon and Bro, 2008). These included survey samples taken directly from vertical profile casts (N = 504) and from shipboard irradiations (see section 2.2) to capture potential components from photo-degraded EEMs measurements (N = 14). Due to higher fluorescent intensities in surface waters relative to deep samples, all EEM spectra were first normalized to unit intensity (i.e., individual fluorescence intensity maxima for each sample was set to 1.0) prior to the modeling process (Murphy et al., 2008). PARAFAC was then applied to the scaled EEM spectra and the model was constructed and further validated using split-half analysis. Once the modeling process was complete, fluorescence intensities were multiplied by their maximum intensities to obtain actual, non-normalized fluorescence intensities for each component in a given sample.
CDOM processing:
Baseline corrections for CDOM absorbance spectra were made by subtracting an offset value that corrects for scattering and refractive index differences between seawater and the MQ blank as described in Reader and Miller (2011). Our capillary waveguide produced a small, reproducible optical resonance (~0.002 m-1) centered close to zero absorbance at the longer wavelengths typically used for blank corrections (e.g., 700–800 nm).
We chose to determine our offset value by fitting the raw absorbance spectra between 630 and 640 nm with a nonlinear fitting routine (“nlinfit” function, MATLAB® 2016 Statistics Toolbox; MathWorks, MA) to (Reader and Miller, 2011): A = Fe-sλ + O
where A is the CDOM absorbance, F is a fitting parameter, S is the spectral slope coefficient, and O is a specific offset value obtained for each sample. We then calculated the corrected CDOM absorbance spectrum by normalizing the raw absorbance spectrum using this offset value and converting to a Napierian absorption coefficient spectrum according to: ag(λ) = 2.303 x A(λ) / L
where ag(λ) (m-1) is the Napierian absorption coefficient of CDOM at wavelength λ, A(λ) (unitless) is the offset-corrected CDOM absorbance at λ, and L (m) is the pathlength (0.922 m).
The specific ultraviolet absorbance (SUVA254, L mg-1 m-1) can be calculated by dividing ag(254) by the DOC concentration (Weishaar et al., 2003), reported by Hansell and associated with this project as cited above. The CDOM spectral slope coefficient (S) for the spectral range 275–295 nm, hereafter referred to as S275-295, can be determined by calculating the slope of the log-transformed linear regression over the wavelength interval of 275–295 nm (Helms et al., 2008).
