As an avid photographer, I totally agree with what Diane Arbus said, “I really believe there are things that nobody would see if I didn’t photograph them.” So here in this blog I’m taking a more photojournalistic approach. Enjoy!
My work in SMAPVEX12 primarily consisted of two tasks: Vegetation sampling in crop fields and soil moisture sampling in forests. The two tasks alternated according to PALS flight schedule and weather conditions. Because I arrived in July, my observations were all about the later phase of the campaign.
Our cropland vegetation sampling involved measurements of optical parameters (e.g., LAI and NDVI) and allometric parameters (e.g., height and diameter). On a typical day we visited up to six fields to collect data and actual plant samples.
Wheat had matured quite a bit since the beginning of the campaign. Here Brian, Hida (U. Guelph), and Tracy were carrying plant samples for further analysis at the ROC.
Tracy (U. Guelph) and Brian (U. Manitoba) were making LAI and NDVI measurements, respectively, in a soybean field.
Example of a typical soil profile: Litter (not shown), then organic layer (brownish orange layer), then soil (gray-colored layer), and then groundwater.
