What is ocean acidification?
The ocean absorbs ~27%
of carbon dioxide emitted
by industry and
deforestation each year.

More Details on Mexico…
Participants
Daniel Pech – ECOSUR
Sharon Herzka - CICESE
Linda Barranco, UABC – Mexico
Gabrielle Cervantes, UABC – Mexico
Alkalinity, underway pH
Frank Hernandez - CICESE. Eggs and larvae
Lucio Loman, Ecosur – Mexico. Pteropods and other zooplankton
5 lines of 7-10 stations each plus 4 net tows on each line.
2 of these lines have been previously sampled by our Mexican colleagues for carbon parameters so we will be able to compare our data with theirs
The lines will also allow us to complete the data gap we have particularly in the southwest GOM. The last line in Mexican waters, in the Yucatan channel, will allow us to characterize the waters going into the GOM (through the loop current).
More Details on Cuba…
Cuban observers on board:
Mr. Jorge Luis Viamontes from GEOCUBA (in Havana)
Dr. Alain Muñoz from CEAC (in Cienfuegos).
4 stations in Cuban waters in the Yucatan channel transect and another 4 in the Florida straits transect.
In the transit between these two lines we will take underway samples every 3-4 hours. Parameters will include: T, S, O2, all 4 carbon parameters, nutrients, chl-a, CDOM, microbiology, ichtyoplankton, etc.
