| description |
Entre los ecosistemas costeros considerados estratégicos en la mitigación del cambio climático se encuentran las praderas de pastos marinos, debido a su alta productividad primaria y altas tasas de captura de carbono. En el presente trabajo se analizó la relación entre la reserva de carbono orgánico en praderas de pastos marinos de la isla de San Andrés, reserva internacional de Biosfera Seaflower, y la dinámica del sistema de carbonatos, con el fin de evaluar cuantitativamente el efecto modulador que la captura de carbono en el pasto marino podría ejercer sobre el sistema de carbonatos en las masas de agua. Se tomaron mediciones de Alcalinidad Total y Carbono Inorgánico Disuelto sobre una pradera de pastos marinos y sobre un punto adyacente sin pasto durante varias épocas climáticas entre 2019 y 2021. Adicionalmente se evaluó la biomasa en pie, biomasa rizoidal y contenido de carbono orgánico en el sedimento de la pradera. Se encontró una fuerte influencia estacional caracterizada por valores de Carbono Inorgánico más bajos durante la época seca. Al mismo tiempo, en la época húmeda la pradera está sujeta a un fuerte fenómeno de remineralización que anula temporalmente el efecto de la captura de carbono sobre el sistema de carbonatos. Los flujos de carbono orgánico e inorgánico alóctono entre la pradera, el bosque de manglar y el arrecife coralino, así como el rol de los organismos calcificadores, surgen como puntos fundamentales a dilucidar para comprender cabalmente el ciclo de carbono inorgánico dentro de la pradera de pasto marino (Texto tomado de la fuente) |

En el presente trabajo se analizó la relación entre la reserva de carbono orgánico en praderas de pastos marinos de la isla de San Andrés, reserva internacional de Biosfera Seaflower, y la dinámica del sistema de carbonatos, con el fin de evaluar cuantitativamente el efecto modulador que la captura de carbono en el pasto marino podría ejercer sobre el sistema de carbonatos en las masas de agua. Se tomaron mediciones de Alcalinidad Total y Carbono Inorgánico Disuelto sobre una pradera de pastos marinos y sobre un punto adyacente sin pasto durante varias épocas climáticas entre 2019 y 2021. Adicionalmente se evaluó la biomasa en pie, biomasa rizoidal y contenido de carbono orgánico en el sedimento de la pradera. Se encontró una fuerte influencia estacional caracterizada por valores de Carbono Inorgánico más bajos durante la época seca. Al mismo tiempo, en la época húmeda la pradera está sujeta a un fuerte fenómeno de remineralización que anula temporalmente el efecto de la captura de carbono sobre el sistema de carbonatos. Los flujos de carbono orgánico e inorgánico alóctono entre la pradera, el bosque de manglar y el arrecife coralino, así como el rol de los organismos calcificadores, surgen como puntos fundamentales a dilucidar para comprender cabalmente el ciclo de carbono inorgánico dentro de la pradera de pasto marino (Texto tomado de la fuente)Among the coastal ecosystems considered strategic in climate change mitigation are seagrass meadows, due to their high primary productivity and high carbon capture rates. In the present work, the relationship between the organic carbon reserve in seagrass meadows of San Andrés Island, an international Biosphere Reserve Seaflower, and the carbonate system dynamics was analyzed to quantitatively evaluate the modulatory effect that carbon capture in seagrass could exert on the carbonate system in water masses. Total Alkalinity and Dissolved Inorganic Carbon measurements were taken over a seagrass meadow and an adjacent point without seagrass during various climatic seasons between 2019 and 2021. Additionally, the standing biomass, rhizoidal biomass, and organic carbon content in the meadow sediment were evaluated. A strong seasonal influence was found, characterized by lower Inorganic Carbon values during the dry season. At the same time, during the wet season, the meadow is subject to a strong remineralization phenomenon that temporarily nullifies the effect of carbon capture on the carbonate system. The fluxes of allochthonous organic and inorganic carbon between the meadow, mangrove forest, and coral reef, as well as the role of calcifying organisms, emerge as fundamental points to elucidate to fully understand the inorganic carbon cycle within the seagrass meadow.The Ocean Foundation es una fundación comunitaria con sede en Washington, D.C. y establecida en 2002.
