Here, 1161 chlorophyll-a fluorescence and oxygen profiles collected between 2003 and 2016 were used to describe statistically the physical situation in which the suboxic-CM was found. Results indicate that the suboxic-CM was a persistent feature at seasonal scale at depths between 40 and 190 m at an average density potential anomaly of 26 ± 0.2 kg m−3, related to the Subtropical Subsurface Water, which is nearly unaffected by mixing with other water masses. The suboxic-CM south of 21°N was generally associated with the upper limit of the suboxic waters of the OMZ. In this region, the distance between the suboxic waters and the euphotic zone (1% of surface irradiance) was > - 25 m year-round, which suggests that persistent low-light levels allow development of the suboxic-CM. The persistence of the suboxic-CM is consistent with its association with a stable microbial community. The effects on the ecosystem and biogeochemical cycles remain to be investigatedThe data used in this work were obtained in the oceanographic campaigns supported by the Consejo Nacional de Ciencia y Tecnologı́a (CONACyT) through the projects CONACyT-2015-02-100 and CONACyT-2014-236864-t.

All oceanographic campaigns were supported by Consejo Nacional de Ciencia y Tecnología (CONACyT), Mexico, through the projects CONACyT-2015-02-100 and CONACyT-2014-236864-t. CONACyT Mexico also granted the main author during his PhD studies.
