\begin{abstract}
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! Mapping tropical wetlands
