The Gulf of California is a source of carbon dioxide to the atmosphere

Water exchange between the Gulf of California and the Pacific Ocean has a significant vertical component (VCWE). Surface (0–200 m) gulf water flows out into the Pacific Ocean and deep (200–600 m) water flows into the gulf. This is a mechanism that allows for the net input to the gulf of dissolved co...

Surface (0–200 m) gulf water flows out into the Pacific Ocean and deep (200–600 m) water flows into the gulf. This is a mechanism that allows for the net input to the gulf of dissolved constituents whose concentrations increase with depth, including dissolved inorganic carbon (DIC). Two scenarios were used to estimate the net input of DIC from the Pacific into the gulf (DICNET INPUT) and to compare this net input with new phytoplankton production in the whole gulf (PNEW) in order to infer if the gulf is a sink or source of CO2. The average annual values of VCWE were 0.67 ± 0.10 Sv in the first scenario and 0.23 ± 0.02 Sv in the second scenario (1 Sv = 106 m3 s–1). After comparing DICNET INPUT with PNEW the result is that the gulf is a source of CO2 to the atmosphere in both scenarios, with an annual average out-gassing of (18.16 ± 6.14) × 1012 and (7.66 ± 2.65) × 1012 grams of carbon in the form of CO2 in the first and second scenarios, respectively. These values are equivalent to an average of 123.5 ± 41.8 and 52.1 ± 18.0 g m–2 yr–1, respectively. The value for the first scenario is higher than the highest value for the eastern equatorial Pacific as reported in the literature (~108 g m–2 yr–1), which leads us to conclude that the value for the second scenario is closer to reality. Key words: Gulf of California, water exchange with the Pacific, new phytoplankton production, CO2 flux from the gulf to the atmosphere.  El intercambio de agua entre el golfo de California y el océano Pacífico tiene un componente vertical (CVIA) significativo. Agua superficial (0–200 m) del golfo fluye hacia el Pacífico y agua profunda (200–600 m) fluye hacia dentro del golfo. Este mecanismo permite el aporte neto de constituyentes disueltos cuyas concentraciones aumentan con la profundidad, incluyendo el carbono inorgánico disuelto (CID). Se utilizaron dos escenarios para estimar el aporte neto de CID del Pacífico al golfo (CIDAPORTE NETO) y compararlo con la producción fitoplanctónica nueva de todo el golfo (PNUEVA) para inferir si el golfo es un sumidero o una fuente de CO2. Los valores promedios anuales del CVIA fueron 0.67 ± 0.10 Sv en el primer escenario y 0.23 ± 0.02 Sv en el segundo (1 Sv = 106 m3 s–1). Comparando CIDAPORTE NETO con PNUEVA el resultado es que el golfo es una fuente de CO2 hacia la atmósfera en ambos escenarios, con promedios anuales de (18.16 ± 6.14) × 1012 y (7.66 ± 2.65) × 1012 gramos de carbono en la forma de CO2, respectivamente. Estos valores son equivalentes a un promedio de 123.5 ± 41.8 y 52.1 ± 18.0 g m–2 año–1, respectivamente. El valor del primer escenario es más alto que el mayor valor para el Pacífico ecuatorial oriental, de acuerdo con reportes en la literatura (~108 g m–2 año–1), lo cual nos conduce a concluir que el valor para el segundo escenario está más cerca de la realidad. 2013-06-01 2021-06-03T03:55:21Z 2021-06-03T03:55:21Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2190 10.7773/cm.v39i2.2190 https://hdl.handle.net/20.500.12930/7452 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2190/1433 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 39 No. 2 (2013); 137-150 Ciencias Marinas; Vol. 39 Núm. 2 (2013); 137-150 2395-9053 0185-3880

description	Water exchange between the Gulf of California and the Pacific Ocean has a significant vertical component (VCWE). Surface (0–200 m) gulf water flows out into the Pacific Ocean and deep (200–600 m) water flows into the gulf. This is a mechanism that allows for the net input to the gulf of dissolved constituents whose concentrations increase with depth, including dissolved inorganic carbon (DIC). Two scenarios were used to estimate the net input of DIC from the Pacific into the gulf (DICNET INPUT) and to compare this net input with new phytoplankton production in the whole gulf (PNEW) in order to infer if the gulf is a sink or source of CO2. The average annual values of VCWE were 0.67 ± 0.10 Sv in the first scenario and 0.23 ± 0.02 Sv in the second scenario (1 Sv = 106 m3 s–1).
