    NASA Sets Sail to Study the Ocean Twilight Zone

    By Sara Blumberg, NASA's Goddard Space Flight Center and Inia Soto Ramos, Universities Space Research Association / GREENBELT, MARYLAND / When we talk about climate change, we tend to think of lush forests with giant trees that passively trap carbon dioxide from the atmosphere and use them for food in a process called photosynthesis. The …

    SnowEx: Little Blogs from the Prairie – Part 1

    SnowEx researchers Andrew Mullen, Eric Sproles, Caitlin Mitchell, and Ross Palomaki finishing up a snow pit profile. Notice how the snow goes from 3 feet deep to almost nothing over relatively short distances.

    Like so many other things, NASA's SnowEx 2021 looks a little different than usual this year. But one thing is business as usual, and that's the participation of undergraduate and graduate students. Students play a pivotal role in SnowEx, from suiting up for data collection to crunching the numbers afterward. The field sites become a …

    Delta-X Field Stories: Collecting “Marsh Popsicles”

    LSU team (Andre, Brandon, Amanda) measuring accretion at their feldspar marker horizon station in coastal Louisiana for NASA's Delta-X

    By Amanda Fontenot, Louisiana State University /NEW ORLEANS, LOUISIANA/ Although most of my work happens in the lab, office, or home, field days are some of the most important days of the year for my research. "Going to the field" is when we get to physically visit the wetlands that we spend so much …
