Circulation in the deep canyon at the entrance to Todos Santos Bay, México, Is there a deep net outflow?

• A 1-year time average current meter (ADCP) observations in a canyon at the entrance of Todos Santos Bay results in a deep outflow.
• The numerical model ROMS is used to investigate the deep circulation in the canyon.
• The outflow in the deep canyon at the entrance of Todos Santos Bay is part of an anticyclonic eddy.

A numerical model was used to investigate the deep circulation in a canyon of Todos Santos Bay, México. The deep canyon current at the entrance of Todos Santos Bay from a numerical model is compared with the annual averaged outflow from observations below 150 m. The model result suggests that this reported outflow is part of an anticyclonic eddy, but more studies are required, both from numerical models and from observations, to know the circulation in that area.
