Presentamos un nuevo sistema natural de di\u00f3xido de carbono (CO2) situado en la costa sur de la isla de La Palma (Islas Canarias, Espa\u00f1a). Al igual que las surgencias de CO2, esta descarga de agua subterranea submarinas de CO2 (SGD) pueden ser utilizados como an\u00e1logos para estudiar los efectos de la acidificaci\u00f3n oce\u00e1nica (AO) en el \u00e1mbito marino. Con este objetivo, presentamos la caracterizaci\u00f3n qu\u00edmica de la zona, describiendo la din\u00e1mica del sistema de carbono, mediante la medici\u00f3n de pH, AT y CT y el c\u00e1lculo de aragonito y calcita. Nuestras exploraciones en la zona han encontrado varios puntos de emisi\u00f3n con caracter\u00edsticas qu\u00edmicas similares. Aqu\u00ed, el TC var\u00eda de 2120,10 a 10 784,84 \u03bcmol kg-1 , AT de 2415,20 a 10 817,12 \u03bcmol kg-1 , el pH de 7,12 a 8,07, el aragonito de 0,71 a 4,15 y la calcita de 1,09 a 6,49 unidades. Asimismo, el flujo de emisi\u00f3n de CO2 var\u00eda entre 2,8 y 28 kg de CO2 d-1, convirti\u00e9ndose en una importante fuente de carbono. Estas emisiones de CO2, de origen volc\u00e1nico, acidifican las aguas subterr\u00e1neas salobres que se vierten a la costa y alteran la qu\u00edmica del agua de mar local. Aunque este tipo de sistema acidificado no es una imagen perfecta de los oc\u00e9anos del futuro, esta zona de La Palma es un lugar excepcional para realizar estudios destinados a comprender el efecto de diferentes niveles de AO en el funcionamiento de los ecosistemas marinos. Estos estudios pueden servir para comprender c\u00f3mo ha persistido la vida en \u00e9pocas pasadas, con mayor CO2 atmosf\u00e9rico, o para predecir las consecuencias del uso actual de combustibles f\u00f3siles en el ecosistema marino de los oc\u00e9anos futuros.<\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/wp.ull.es\/omacc\/wp-content\/uploads\/sites\/110\/2022\/04\/Gonzalez-delgado-et-al.-2021.BG_.pdf\u00bb url_new_window=\u00bbon\u00bb button_text=\u00bbDescargar pdf\u00bb _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb custom_button=\u00bbon\u00bb button_text_size=\u00bb13px\u00bb button_bg_color=\u00bb#0C997F\u00bb][\/et_pb_button][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=\u00bb2_5,3_5″ _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb][et_pb_column type=\u00bb2_5″ _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb][\/et_pb_column][et_pb_column type=\u00bb3_5″ _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb][et_pb_toggle title=\u00bbEnglish\u00bb open_toggle_text_color=\u00bb#0C997F\u00bb open_toggle_background_color=\u00bb#FFFFFF\u00bb closed_toggle_text_color=\u00bb#0C997F\u00bb closed_toggle_background_color=\u00bb#FFFFFF\u00bb icon_color=\u00bb#0C997F\u00bb _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb title_font=\u00bb|||on|||||\u00bb closed_title_font=\u00bb|||on|||||\u00bb closed_title_font_size=\u00bb14px\u00bb closed_title_line_height=\u00bb1.5em\u00bb custom_padding=\u00bb7px||7px||true|false\u00bb border_color_all=\u00bb#0C997F\u00bb]\n

We present a new natural carbon dioxide (CO2) system located off the southern coast of the island of La Palma (Canary Islands, Spain). Like CO2 seeps, these CO2 submarine groundwater discharges (SGDs) can be used as an analogue to study the effects of ocean acidification (OA) on the marine realm. With this aim, we present the chemical characterization of the area, describing the carbon system dynamics, by measuring pH, AT and CT and calculating aragonite and calcite. Our explorations of the area have found several emission points with similar chemical features. Here, the CT varies from 2120.10 to 10 784.84 \u03bcmol kg\u22121, AT from 2415.20 to 10 817.12 \u03bcmol kg\u22121, pH from 7.12 to 8.07, aragonite from 0.71 to 4.15 and calcite from 1.09 to 6.49 units. Also, the CO2 emission flux varies between 2.8 and 28 kg CO2 d\u22121, becoming a significant source of carbon. These CO2 emissions, which are of volcanic origin, acidify the brackish groundwater that is discharged to the coast and alter the local seawater chemistry. Although this kind of acidified system is not a perfect image of future oceans, this area of La Palma is an exceptional spot to perform studies aimed at understanding the effect of different levels of OA on the functioning of marine ecosystems. These studies can then be used to comprehend how life has persisted through past eras, with higher atmospheric CO2, or to predict the consequences of present fossil fuel usage on the marine ecosystem of the future oceans.<\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
