Factors determining the ocean–atmosphere CO2 flux variability in 5 coastal zones of the Gulf of California

Factors determining the ocean–atmosphere CO2 flux variability in 5 coastal zones of the Gulf of California

The Gulf of California (GC) features many oceanographic processes. It communicates with the Pacific Ocean via a surface water outflow (0–200 m) with relatively low dissolved inorganic carbon (DIC) values and a water inflow (200–600 m) with high DIC values. Data on the marine carbon system in the GC...

description The Gulf of California (GC) features many oceanographic processes. It communicates with the Pacific Ocean via a surface water outflow (0–200 m) with relatively low dissolved inorganic carbon (DIC) values and a water inflow (200–600 m) with high DIC values. Data on the marine carbon system in the GC are scarce and most have been taken from the Midriff Islands region, in the central part of the gulf. We explored possible forcing agents that control the ocean–atmosphere CO2 flux (fCO2) variability in 5 coastal zones of the GC. We carried out 6 oceanographic cruises in 5 regions: off northern Sinaloa in September 2016 (NAV2016) and in March 2017 (NAV2017), in the Guaymas Basin (central gulf) in September 2016 (GUA2016), in Concepción Bay (Baja California Sur) in July 2017 (BC2017), in Mulegé (Baja California Sur) in July 2017 (MUL2017), and off Mazatlán (southern gulf) in July 2017 (MAZ2017). We measured temperature, salinity, DIC, and total alkalinity and calculated the surface water partial pressure of CO2 and fCO2. We also used sea surface height anomaly with geostrophic flow, sea surface temperature, and chlorophyll concentration data from satellite imagery to generate composites for the sampling days. The lowest temperature, highest DIC, and negative fCO2 were registered in NAV2017. NAV2016, GUA2016, and BC2017 showed the highest temperatures; and MUL2017 and MAZ2017, intermediate temperatures. The most contrasting fCO2 values occurred in GUA2017 (0.56 ± 0.46 mmol C·m–2·d–1) and MAZ2017 (–2.26 ± 1.85 mmol C· m–2·d–1). In general, fCO2 is determined by the oceanographic conditions of each study area.

In general, fCO2 is determined by the oceanographic conditions of each study area. El golfo de California (GC) presenta diversos procesos oceanográficos. Tiene comunicación con el océano Pacífico mediante un flujo de salida de agua superficial (0–200 m) con valores relativamente bajos de carbono inorgánico disuelto (CID) y un flujo de entrada de agua (200–600 m) con valores altos de CID. Los datos sobre el sistema de carbono marino en el GC son escasos, y la mayoría proviene de la región de las islas grandes, en el centro del golfo. Se exploraron los posibles agentes forzantes que controlan la variabilidad del flujo de CO2 océano-atmósfera (fCO2) en 5 zonas costeras del GC. Se realizaron 6 cruceros oceanográficos en 5 regiones: frente al norte de Sinaloa en septiembre de 2016 (NAV2016) y marzo de 2017 (NAV2017), en la cuenca de Guaymas (centro del golfo) en septiembre de 2016 (GUA2016), en bahía Concepción (Baja California Sur) en julio de 2017 (BC2017), en Mulegé (Baja California Sur) en julio de 2017 (MUL2017) y frente a Mazatlán (golfo sur) en julio de 2017 (MAZ2017). Se midió la temperatura y la salinidad, se estimó el CID y la alcalinidad total y se calculó la presión parcial de CO2 superficial y el fCO2. Se utilizaron imágenes de satélite para generar compuestos de la anomalía del nivel del mar con flujo geostrófico, la temperatura superficial del mar y la concentración de clorofila en los días de muestreo. La temperatura más baja, el CID más alto y el fCO2 negativo se registraron en NAV2017. NAV2016, GUA2016 y BC2017 registraron las temperaturas más altas, y MUL2017 y MAZ2017, temperaturas intermedias. Los mayores contrastes de fCO2 ocurrieron en GUA2017 (0.56 ± 0.46 mmol C· m–2·d–1) y MAZ2017 (–2.26 ± 1.85 mmol C· m–2·d–1). En general, el fCO2 está determinado por las condiciones oceanográficas de cada zona de estudio.
