“…From January to April, there is low precipitation (350 mm month -1 ) and the thermocline is at its shallowest position (7.5 m), allowing for the lifting of cool, high-salinity, nutrient rich, and low-oxygen deep waters (25°C, 30.8 PSU, 0.6 mg L -1 of Chl-a, 4.0 mg O 2 L -1 ). For the rest of the year, precipitation increases (587 mm month -1 ), and the thermocline deepens (47 m), allowing for warmer and more oxygenated waters to occurs, but with lower salinity and chlorophyll-a conditions (27°C, 4.9 mg O 2 L -1 , 29.8 PSU, 0.1 mg L -1 of Chl-a) (Giraldo et al, 2008;Blanco, 2009;Giraldo et al, 2014;Sampson and Giraldo, 2014;Zapata, 2017;Castrilloń-Cifuentes et al, 2023). Changes in pH did not reveal a temporal pattern (Ramıŕez-Martıńez et al, 2022).…”
