Science AMA Series : We’re a team of researchers studying where wetlands can be found around the globe, from the arctic to the tropics, and trying to understand how human land use activities and climate change are affecting their distribution.

Hi, we’re Drs. Ben Poulter (NASA), Thomas Gumbricht (CIFOR), David Olefeldt (University of Alberta) and Etienne Fluet-Chouinard (University of Wisconsin) — we study techniques to map wetlands around the world, how they change over time, and how this information can be used to understand how wetlands function and provide ecosystem services to people. Wetlands can be mapped using a variety of techniques, from sending people out into the field using inventory techniques to taking advantage of satellites in orbit around the Earth and using the electromagnetic spectrum. Recently, a new map of tropical wetlands was published by Thomas Gumbricht as well as a high-resolution map of global surface inundation by Etienne Fluet-Chouinard, both databases are being used for a variety of purposes, including to understand how wetland affect climate change by emitting methane. Join our AMA to find out how satellites are helping in the quest to learn more about where wetlands are located, how human activities affect wetland area, and how climate change is affecting methane emissions from wetlands. We’ll be back at 12 pm ET to answer your questions, AMA!
