“…Samples collected during these cruises and their analysis in CIGoM laboratories enabled us to establish the spatial and temporal patterns of the physical and geochemical variables (Damien et al, 2018;Portela et al, 2018;Medina-Goḿez et al, 2020;Ochoa et al, 2021;Cervantes-Díaz et al, 2022;Hernández-Sánchez et al, 2022;Lee-Sańchez et al, 2022;Valencia-Gasti et al, 2022;Velásquez-Aristizábal et al, 2022;Romero-Arteaga et al, 2022a;Romero-Arteaga et al, 2022b) related to the carbon cycle (as well as hydrocarbons (García-Bautista et al, 2022) metals and pollutants concentrations in the water column (Arenas-Islas et al, 2019;Hernańdez-Candelario et al, 2019;Árcega-Cabrera et al, 2021;Dotor-Almazań et al, 2021a;Dótor-Almazán et al, 2021b;Dotor-Almazań et al, 2021b;Árcega-Cabrera F. et al, 2022;Dotor-Almazań et al, 2022a;Do ́tor-Almaza ́n et al, 2022b), sediments, as well as in tissues of selected organisms.…”

The tragic accident of the Macondo platform operated by British Petroleum (BP) unleashed in 2010 one of the largest oil spills in history, lasting over three months, spilling nearly 500 million liters of oil in one of the most biodiverse ocean regions. This accident revealed the technological deficiencies for the control of a spill in deep waters of the hydrocarbon industry. Simultaneously it showed important gaps in knowledge to predict the propagation and fate of the large volumes of hydrocarbons at depth and on the surface ocean and, more importantly, on their impact on the great ecosystem of the Gulf of Mexico. The necessity to understand and predict the transport, fate and ecosystem-level impacts of large oil spills in the southern Gulf of Mexico, a key region for oil exploration and extraction, led policymakers, scientists, and industry representatives from PEMEX (the Mexican oil company) to jointly launch an ocean observation project (2015-22) aimed to provide a multi-layered environmental baseline, develop a modern monitoring and computational modeling capacity and promote scientific understanding of the marine environment throughout the Mexican Exclusive Economic Zone (EEZ). The initiative, led by the Research Consortium for the Gulf of Mexico (CIGoM), brought together more than 300 multidisciplinary researchers from more than a two dozen institutions in Mexico and abroad, including the Centre for Scientific Research and Higher Education of Ensenada (CICESE) as the leading institution, the National Autonomous University of Mexico (UNAM), the Centre for Research and Advanced Studies of the National Polytechnic Institute (CINVESTAV) in Mérida, the Autonomous University of Baja California (UABC), and the Centre for Engineering and Industrial Development (CIDESI). Financial support was provided by the National Council for Science and Technology and the Ministry of Energy Hydrocarbon Fund.

“…Several calibration strategies for the determination of element concentrations in carbonate matrices by portable XRFS were proposed. Arenas-Islas et al 313 prepared 11 gravimetric mixtures of NRCC CRM PACS-3 (marine sediment) with reagent grade CaCO 3 in different proportions to act as calibration standards for the analysis of carbonate sediments. The CaCO 3 reagent and 11 mixtures were also analysed by FAAS and ETAAS after total digestion to check their trace metal contents.…”
