Ocean acidification monitoring in the Mexican Pacific (in Spanish) (text & video)

OA Week 2021, LAOCA (Latin America & Caribbean) Hub ​Session

Dr. Leticia Espinosa Carreón, Instituto Politécnico Nacional – CIIDIR Sinaloa, Mexico

Description: With the support of the Secretariat of the Navy, Mexican Navy (SEMAR) and the National Institute of Fisheries and Aquaculture (INAPESCA), it has participated in 13 oceanographic cruises from Tijuana, BC, to Chiapas, covering the entire Mexican Pacific since 2016 to 2021. Six students are developing their Master of Science and PhD thesis. Some of the results obtained are presented. In 2016, CO2 sequestration was recorded in five of six areas of the Gulf of California. In the tropical Pacific zone, it was registered in April 2017 as a source of CO2, while, in the same region, in April 2018, a sink. In the Baja California Sur region in 2019, the relationship between DIC and water masses was presented. In Baja California and Baja California Sur, a latitudinal transect shows the sinking of the isotherms and the influence of the water of the California Current from north to south, as well as the latitudinal variation of some species of coccolithophores.
