Satellite Observations in Support of
LME Governance: A Case Study for Data Exchange in the Wider
Caribbean LME
Exchange of Experiences on LME- related data and information issues
Buenos Aires, Argentina, June, 2013
Requirement for Dynamic LME Governance
2
Governance requires ‘knowledge’ (understanding of what is happening). Knowledge has to be:Co-derived (joint natural + social science
effort)Inexpensive to local governmentsTimely
LMEs are ‘Large’: They require a synoptic framework of observations
LME’s change continuously: They require time series of observations
Synoptic ocean time series
3
Regional-global context to understand processes, stocks, and diversity within different parts of a dynamic LME
Means to quantitative measure change in LME’s
Place point observations in regional context
Initialize and validate simulations / ecological forecasting
Today’s Tools
4
Atlas – today we can show dynamic aspects of an ecosystem
Climatologies (monthly, annual) as ‘baseline’ to measureshort-term changeLong-term trendsOccurrence and impacts of extreme events
Time series (observations and anomalies)Other dynamic information: individual
historic and current observations, forecasts
Prototype datasets for the Caribbean

What is the relation between Climate Change and Coral
(benthic) health?
Eakin et al. (2010)
Application 5: Thermal Stress and Coral Bleaching
A) Maximum NOAA Coral Reef Watch Degree Heating Week (DHW) during 2005.
(B) means of coral bleached as either percent live coral colonies (circles) or cover (diamonds).
15
Can we identify benthic composition?
Is Coral (benthic) coverage changing over time?
• Benthic coverage is affected by natural / anthropogenic events
• Need to monitor / understand interannual variations and ecological shifts
Application 6: Mapping Benthic Coverage
Classified dataset based on Landsat for Looe Key Reef (red: coral, brown: covered hardbottom, yellow: bare hardbottom, green: sand. Palandro et al. (2008)
Decision Support Tools for an Ecosystem
Based ManagementDeveloping a flexible framework for integrated, distributed,
and interlinked regional coastal and marine data atlases based on the NOAA Gulf of Mexico
data atlas
16
Goals
Integrate scientific and socio-economic information through an online data atlas to help visualize and analyze historical datasets, understand connectivity, trends, and variabilityin order to help assess the socio-economic implications
Objectives:
• Identify and integrate additional specific data sets
• Implement a framework for embedding regional data atlases
• Enhance the user interface of existing web-based data atlas(es) for displaying, querying and analyzing information, providing meaningful statistics for decision-making
• Develop a prototype for a mobile platform

Use existing datasets developed for the Caribbean LME atlas as initial layers for the IODE Caribbean Marine Atlas: (http://www.caribbeanmarineatlas.net/)
Link the Gulf of Mexico and Caribbean Atlases
Develop a framework for an integrated global atlas that:Uses existing (easily available) ocean and land
satellite dataProvides the framework and technology tools to
incorporate new regions around the worldDevelop an inter-operable data platform
