Below are a few photos of tidal wetlands along the Connecticut River in Essex, CT taken this week during low tide, exposing mud flats. Tidal wetlands provide habitat, nesting, feeding, and refuge areas for shorebirds; serve as a nursery for many species found in the Long Island Sound. The Connecticut River was designated as an Wetland of International Importance by RAMSAR, and is the largest river system in New England. The river includes fresh, salt and brackish tidal wetlands and is a key component linking the Long Island Sound and upland fresh water systems.

Below is a link for a few podcasts by the Radio New Zealand program Our Changing World about wetlands. I hadn't known Zealand had lost an astounding 90% of its wetlands over the last century. The podcasts arent very long, but are worth a listen.

Other related stories featured on Our Changing World include the ecology of Waituna Lagoon, flipping (inversion) lakes, and monitoring water quality.

Through Stumbleupon, I found a list of 60 free online Computer Sciences courses one of which is Advanced Topics in GIS provided by UC Santa Barbara.

The course description is as follows:

"A series of intensive lab sessions focused on specific computational languages (e.g., Python, R, shell) and tools (e.g., GDAL/OGR, InVEST, MGET, ModelBuilder) applied to the spatial analysis of environmental problems." and reviews Python Programming, the Open-Source QGIS program, Google Earth and Leaflet.
