Follow-up meeting related to the Thermal Dome initiative, which reported on the activities carried out since the Workshop Seminar held in San Jose, Costa Rica in November 2023. A dissemination program is promoted in each country and the designation of focal points; the creation of national work teams, as a requirement of the IMO, to designate a consultant to support the formulation of Particularly Sensitive Areas in Altamar (PSSA).
The Thermal Dome of Costa Rica (DTCR) is a scenographic phenomenon resulting from the action of winds and ocean currents that produce the vertical displacement of deep, cold and nutrient-rich waters that approach the surface, creating a suggestive zone. It is located in the Eastern Tropical Pacific, west of Central America and can measure between 300 and 1000 kilometers wide. The identification of the 20°C thermocline at 35 meters depth has been one of the most useful ways to delimit this phenomenon variable in size and position during the year. More information.
