Exploring the land-ocean biogeochemical and microbial connectivity in the Ría de Vigo (NW Iberian Peninsula) through submarine groundwater dischargeBernal Rodríguez, CristinaTeira, EvaCalvo-Martín, ElisaJustel, MaiderÁlvarez-Salgado, Xosé AntónRocha, CarlosPaz, M. de laÁlvarez-Rodríguez, MartaIbánhez, J. Severino P.Submarine groundwater dischargeCoastal aquiferSubterranean estuaryMicrobial diversitAquatic connectivitySandy sediments12 pages, 8 figuresIncreasing evidence demonstrates the widespread occurrence of submarine groundwater discharge (SGD) in coastal zones, where it may influence biogeochemistry and microbial ecology. Here, we analyze the biogeochemical composition and microbial communities across diverse aquatic environments in a highly productive coastal system (Ría de Vigo, NW Iberian Peninsula), influenced by significant fresh SGD, to assess the extent of microbial and biogeochemical connectivity—i.e., mass transfer—among them. Samples were collected from surface and deep porewaters from two subterranean estuaries (STEs), surface seawater, riverine water, and continental groundwater. These samples were analyzed for a comprehensive set of microbial and biogeochemical variables, including radioisotopes used as SGD tracers. A significant correlation between SGD tracers and carbonate system parameters, N2O, and CH4 concentrations in surface seawater indicates SGD influences biogeochemistry of the embayment. However, some of these solutes do not originate from continental groundwater but are produced in the local STEs, which act as biogeochemical reactors modifying fresh SGD. The findings also reveal highly diverse microbial communities, with higher diversity in STEs due to the variety of niches present. Indicator taxa included the phyla Euryarchaeota, Chloroflexi, Omnitrophicaeota, and the family Nitrosopumilaceae in STEs; the phylum Cyanobacteria and the family Burkholderiaceae in freshwater endmembers; and the Flavobacteriaceae and Cryomorphaceae families in seawater. Most operational taxonomic units (∼87 %) were unique to a single environment (river, continental groundwater, coastal water, or STE), showing STEs limit subterranean microbial transfer between groundwater and marine ecosystems. Our results highlight STEs as reservoirs of diversity and zones of intense biogeochemical reactivityThe following projects have funded this research. - The SUBACID project (CLNE/2017/210), funded by the Irish Research Council and the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No713279 through the CAROLINE program. - The UNDERGROUND project (ACAM, 2022020014- CA25842), part of the Galicia Marine Science programme which belongs to the Complementary Science Plans for Marine Science of Ministerio de Ciencia, Innovación y Universidades included in the Recovery, Transformation and Resilience Plan (PRTR-C17.I1), funded through Xunta de Galicia with NextGenerationEU and the European Maritime Fisheries and Aquaculture Funds. - The INTEGROUNDS Project (TED2021-130020B-C21), funded by MCIN/AEI/10.13039/501100011033 and the European Union “NextGenerationEU”/PRTR.
