This week on Blue Dot, we look at how we measure the amount of snowpack in the Sierra Nevada.  We hear from Steve Margulis, a hydrology professor at the University of California, Los Angeles, and Michael Durand, a professor at Ohio State University. They both help give us the numbers that tell how much water (we think) is in the Sierra Snowpack, how much meltwater we'll have to use as a state, and how long it will take the snowpack to recover from drought.

Dave Schlom is the longtime host and creator of Blue Dot. From surfing to Voyager in interstellar space, rock guitar to orcas in our imperiled oceans, the topics on Blue Dot are as varied as the host’s interests and connections -- which are pretty limitless! An internationally respected space history journalist, Dave is also deeply fascinated by all aspects of the grand workings of nature’s awesome machinery on scales ranging from galactic to subatomic. And topics take in all aspects of the arts and sciences.
