Citizen Scientists Needed!

We need your help to better understand the ecology of the salt marsh.

For several years (2010 to 2016) we photographically mapped part of a salt marsh landscape at the Georgia Coastal Ecosystems-LTER site (A). We studied an area of ~3,200 m2.  Dots indicate locations of soil samples and Real-Time Kinematic GPS control points (~1 cm resolution).  This area was photographed with ~11,000 overlapping digital images (B, plastic lid marks a GPS/soil point) each year. The images will be aligned by volunteers (C), overlaid on an elevation and soil map, and analyzed by volunteers to document the abundance of different plant species and the density of marsh macro-invertebrates such as mussels, crabs, and snails. 

The outcome of this project will be a high-resolution map of species distributions over a relatively large area. It will allow us to study spatial distributions of species in ways we've never been able to do so before. And we'll be able to see how these spatial distributions change over time from year to year.

It's an exciting project but we need your help! Neither task (aligning photographs or identifying species in the photographs) can be done by hand. But Citizen Science volunteers can do them online.

You can help align photographs here: (control-click to open in a new window).

You can help identify species in the photographs here: (coming soon; working on final technical issues).

As you work on these projects, you'll also learn a little bit about salt marshes. Thanks for your help!
