Surfactants account for minor fractions of total organic carbon in the ocean but can significantly influence production primary marine aerosol particles (PMA) at sea surface via modulation bubble tension. During September and October 2016, model PMA (mPMA) were produced from seawater by bursting bubbles two biologically productive oligotrophic stations western North Atlantic Ocean. Total concentrations surfactants extracted mPMA quantified characterized measurements tension isotherms...
Marine refractory dissolved organic carbon is emitted to the atmosphere in primary marine aerosol.
Abstract. Ocean alkalinity enhancement (OAE) is a promising approach to marine carbon dioxide removal (mCDR) that leverages the large surface area and storage capacity of oceans sequester atmospheric CO2 as dissolved bicarbonate (HCO3-). The SEA MATE (Safe Elevation Alkalinity for Mitigation Acidification Through Electrochemistry) process uses electrochemistry convert some salt (NaCl) in seawater or brine into aqueous acid (HCl), which removed from system, base (NaOH), returned ocean with...
Abstract. Ocean alkalinity enhancement (OAE) is a promising approach to marine carbon dioxide removal (mCDR) that leverages the large surface area and storage capacity of oceans sequester atmospheric CO2 as dissolved bicarbonate (HCO3-). One OAE method involves conversion salt in seawater into aqueous (NaOH), which returned ocean. The resulting increase pH causes shift inorganic (DIC) speciation toward carbonate decrease ocean pCO2. pCO2 results enhanced uptake by due gas exchange. In this...
Abstract During September–October 2016, a marine aerosol generator configured with forced‐air Venturis was deployed at two biologically productive and oligotrophic regions of the western North Atlantic Ocean to investigate factors that modulate primary (PMA) production. The produced representative bubble size distributions Hinze scales (0.32 0.95 mm radii) void fractions (0.011 0.019 L air sw ‐1 ) overlapped those plumes in surface ocean by breaking wind waves. varied among seawater...
ABSTRACT Precise manometric pressure, volume, and temperature (P-V-T) measurements of carbon in samples, standards, blanks are critical for radiocarbon studies. While P T uncertainties depend on instrument choice environmental stability, V their method measurement often overlooked. We used numerical simulations error propagation to find optimum procedures measuring “cold-finger” volumes equipped with capacitance diaphragm gauges (CDGs) by two common application Boyle’s Law: cryogenic...
Abstract The moderate DI 13 C isotope enrichment (MoDIE) method by Powers et al. (2017) is a promising to precisely measure the photochemical mineralization of dissolved organic carbon (DOC) in water samples without dramatically altering sample's pH or pool. Here, we evaluated analytical uncertainties MoDIE and used Monte Carlo simulations optimize experimental design for most precise measurements inorganic (DIC) that produced photochemically (DIC hν ). Analytically, recommend calculating...
