Main topics
Multiple spatio-temporal scales (variability)
Some oceanographic aspects of the Western Caribbean
Marine resources: Food, habitat, energy
Examples of marine resourses and oceanographic processes in the Western Caribbean
Current studies and monitoring
Scales and variability
There different spatio-temporal scales. From that variability, there are physical processes clearly indentified.
Large scale, mesoscale, submesoscale, small scale
Significant signal, can be identified from observations

Drifters trajectories
Carrillo et al, submitted to CSRPathways and hydrography in the Mesoamerican Barrier Reef SystemPart 1: Circulation
Biology : life cycle, Early LIFEDispersion, life cycle of these marine resources linked directly with oceanographic proceses
Life cycle, spawning,dispersion
Large scale-Pelagic fish: Tuna
Regional scale: Lobster
Subregional: Queen Conch, Reef fish ( Lutjanidae and Groupers)
Pelagic fish: Tuna as a large scale connectivity
Tuna in the Atlantic,, Mediterranean and Gulf of mexico as spawning, but also the Caribbean and then studies of the project from NOAA, and now a collaboration by using oceanographic cruises, campaings.Project ECOlogía trófica comparativa de LArvas de aTUN rojoatlántico (Thunnus thynnus) de las áreas de puesta del Medterraneo-NO y el Golfo de México. Laiz et al
Bluefin tuna: Thunnus thynnus
Muhling et al. 2011
Bluefin tuna: Thunnus thynnus
Other pelagics
Southern Mexico
Thunnus atlanticus
Southern Belize
Blackfin Tuna
Sail fish, Istiophorus platypterus

Monitoring and current studies
Regional scale: Remote sensing,
Biophysical Numerical models
Direct observations (This is key) by:
Oceanographic campains (bio-physical aspects)
Coastal observations
Understanding:
variability
Links with resources, example the mesoamerican, recruitment and physcal processes experiment
Coastal observational programs
CAPACITY BUILDING
Capacity building and monitoring in the Mesoamerican Barrier Reef System
Oceanographic campaings
