We are indebted to the personnel of the Fundación La Salle de Ciencias Naturales, Estación de Investigaciones Marinas de Margarita (FLASA/EDIMAR) for their enthusiasm and professional support. In particular we thank the Hno. Ginés (Dr. Pablo Mandazen Soto), founder of the Fundación La Salle and the Hno. José Pereda, president, for their confidence in our activities. We also thank the crew of the R/V Hermano Ginés (FLASA) for their able support at sea. Aitzol Arrellano, Glenda Arias, José Jesús Narvaez, Javier Gutierrez and Juan Capelo (all at FLASA/EDIMAR) regularly provide essential field and laboratory support. Jonnathan Garcia, Anadiuska Rondon, John Akl, Ana Lucia Odriozola, Luis Troccoli, Wilfredo Patiño, Luis Sanchez, William Senior, José Rafael Díz have been part of the project, enriching it with their own expertise. We also thank all the research scientists that have taken an interest in the Cariaco Basin. Through their meticulous studies, they have enabled the scientific community and general public to understand ocean processes a little better, highlighting the importance of ocean conservation and long term ocean time series.
