Abstract

The Great Lakes Optical Properties Geospatial Database (GLOPGD) is a representation of in situ optical and water quality measurements made in all five of the Great Lakes over the last 15 years. This geospatial database has been collected by various leading groups and institutions such as the NOAA Great Lakes Environmental Research Lab, the Upstate Freshwater Institute, the Michigan Tech Research Institute (MTRI) and others in the Great Lakes to help better understand long term changes due to anthropogenic forcing, climate change, and invasive species. This is the first time that these data have been made widely available to Great Lakes scientists and stakeholders through the web (glopgd.org). GLOPGD contains spatially-located optical data such as the diffuse attenuation coefficient (Kd), Remote Sensing Reflectance (Rrs), KdPAR, absorption, backscatter, and photic zone depth as well as many other parameters. Water chemistry data includes concentration measurements of chlorophyll a, dissolved organic carbon (DOC), total and volatile suspended solids (TSS and VSS) as well as colored dissolved organic matter (CDOM). GLOPGD allows users to "map" these available parameters to provide better access to area of interest data sets. Queried data will available for download in a number of file types including shapefiles, KML, and CSV.
