Effects of wave-powered water pump upwelling on kelp mariculture: a case study for Gulf of Maine
This study investigates the feasibility of wave-powered upwelling to enhance kelp mariculture productivity in the Gulf of Maine, a region experiencing nutrient limitation and seasonal warming. Through a coupled physical-biogeochemical model calibrated with empirical oceanographic data, researchers estimate that wave-powered upwelling can reduce water temperatures by 1.0 ± 0.15 °C and increase nitrate concentrations by 0.1−1.1 µmol L−1, potentially yielding an additional 9.5%–10%+1.6% kelp biomass annually. This framework highlights wave-powered upwelling as a promising, scalable strategy for sustainable aquaculture, as further explored
Harnessing the microbial carbon pump: prospects and challenges for coastal carbon sequestration
The Marine Microbial Carbon Pump (MCP) represents a promising, yet complex, avenue for coastal carbon sequestration. Recent research validates the MCP’s significant contribution to the global ocean carbon reservoir, with coastal systems responsible for 40–60% of recalcitrant dissolved organic carbon (RDOC) production. This review synthesizes advancements in technologies aimed at enhancing this natural carbon sink, highlighting challenges including low RDOC conversion efficiency and potential ecological risks.
