Cross walking to the New Coastal and Marine Ecological Classification Standard (CMECS) Mark Finkbeiner and Chris Robinson NOAA Coastal Services Center EBM Tools Webinar 16 May 2013
Outline What is CMECS Value of, and process for, crosswalking Approach for developing the crosswalk tool Tool demonstration
CMECS Structure Components Biogeographic Setting Water Column Component (WC) Biotic Component (BC) Substrate Component (SC) Geoform Component (GC) Structure and features of water column Assemblages of benthic and suspended/floating organisms Character and composition of surface and near surface substrates Geomorphic and structural character of coast or seafloor Modifiers Aquatic Setting Biotope: Combination of abiotic features and associated species
Why crosswalk? Crosswalk considerations Crosswalk Considerations Translate historical data Integrate data from different sources Test CMECS Scale/resolution differences Unit threshold differences Classification detail differences Habitat vs. landscape elements Source data/map considerations
Unit to Unit Relationships Equal Nearly Equal Greater Than Less Than Overlapping No Equivalent SCHEME Sand Mixed Fines Macroalgae Concrete Blocks Detrital Floor Sediment Depth CMECS Sand Sandy Mud Benthic or Floating Macroalgae Construction Rubble Organic Detritus
SCHEME CMECS SCHEME vegetation classes crosswalk to equivalent Biotic Component units SCHEME units include percent cover as classifier SCHEME modifiers generally crosswalk to anthropogenic geoforms and biotic subgroups Equal Nearly Equal Greater Than Less Than Overlapping No Equivalent
Classifications to be Crosswalked System for Classifying Habitats in Estuarine and Marine Environments (SCHEME) Habitat and Land Cover for Classification for National Estuarine Research Reserve System (NERRS) Cowardin NOAA Biogeography Greene et al. Auster et al. ShoreZone (planned) EUNIS (planned)
Goals for a Crosswalk Tool GIS Based Tool (ArcGIS 10.x) Translates benthic cover data into CMECS system Initially built for SCHEME Flexibility for additional crosswalks (No hardcoding) Start with and end with spatial data outputs
Approach Builds on source system hierarchical structure and units Settings added as attributes to component feature layers Model addresses Geoform, Substrate, and Biotic Components Modifiers yet to be addressed External Look up tables drive the model decisions Strictly numeric code for CMECS units
