Arrecifes coralinos del Pacífico mexicano en el contexto de la AO (in Spanish) (text & video)

OA Week 2021, North American Hub Session

Dr. Orion Norzagaray, Instituto de Investigaciones Oceanológicas-Universidad Autónoma de Baja California, Mexico

Description: Coral reefs and coral communities from the Eastern Tropical Pacific (ETP) develop under harsh conditions, since they live in environments with low temperature, high nutrient content and sub-saturated with regard to aragonite. These conditions convert this region, and the ecosystems inhabiting there, in natural laboratories for ocean acidification studies (OA) on corals. Studies on carbonate balance in these ecosystems indicate that they present low production values, commonly based on a small number of species. In addition, studies on the dynamics of the carbonate system in these environments highlight that the seasonal controls vary between regions, promoted by oceanographic processes, which have a local to regional footprint. This talk aims to show relevant aspects of the carbonate cycle in these environments, specifically those on the coasts of Mexico, and place them in the context of OA.

Ocean Acidification Week 2021 was sponsored by the following organizations:

(1) GOA-ON, the Global Ocean Acidification Observing Network,

(2) NOAA, the United States National Oceanic & Atmospheric Administration,

(3) IAEA OA-ICC, the International Atomic Energy Agency – Ocean Acidification International Coordination Centre, and

(4) IOC-UNESCO – the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization
