Abstract The effects of heterogeneous reactions between river‐borne particles and the carbonate system were studied in plumes Mississippi Brazos rivers. Measurements within these revealed significant removal dissolved inorganic carbon (DIC) total alkalinity (TA). After accounting for all known DIC TA sinks sources, (i.e., CaCO 3 precipitation cation exchange adsorbed ions) found to be responsible a fraction removal, exceeding 10% 90%, respectively, plume waters. This finding was corroborated...
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. Marine carbon dioxide removal (mCDR) approaches are under development to mitigate the effects of climate change with potential co-benefits local reduction ocean acidification impacts. One such method is alkalinity enhancement (OAE). A specific OAE that avoids issues solid dissolution kinetics and release impurities into generation aqueous via electrochemistry enhance surrounding water extract acid from seawater. While electrochemical extraction a promising for increasing...
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 In addition to steep carbon emission reductions, all modeled pathways reach global climate goals require removal. Marine dioxide removal has the potential play a large role in drawing down legacy anthropogenic emissions due scalability and durability of proposed methods. While this field is rapidly expanding, number issues remain, including efforts grow industry, align projects with equity justice goals, ensure development trusted, unique, durable credits. We, group early career...
Abstract. Marine carbon dioxide removal (mCDR) approaches are under development to mitigate the effects of climate change by sequestering in stable reservoirs, with potential co-benefit local reductions coastal acidification impacts. One such method is ocean alkalinity enhancement (OAE). A specific OAE generation aqueous via electrochemistry enhance receiving water extraction acid from seawater, thereby avoiding issues solid dissolution kinetics and release impurities into alkaline minerals....
This study describes the development of CHANnelized Optical System II (CHANOS II), an autonomous, in situ sensor capable measuring seawater dissolved inorganic carbon (DIC) at high frequency (up to ∼1 Hz). In this sensor, CO2 from acidified is dynamically equilibrated with a pH-sensitive indicator dye encapsulated gas-permeable Teflon AF 2400 tubing. The pH measured spectrophotometrically and can be quantitatively correlated sample DIC. Ground-truthed field data demonstrate sensor's...
Abstract Marine CO 2 removal (CDR) using enhanced-alkalinity seawater discharge was simulated in the estuarine waters of Salish Sea, Washington, US. The high-alkalinity would be generated bipolar membrane electrodialysis technology to remove acid and alkaline stream returned sea. Response receiving evaluated a shoreline resolving hydrodynamic model with biogeochemistry, carbonate chemistry. Two sites, two deployment scales, each enhanced TA 2997 mmol m −3 pH 9 were simulated. effects on...
