Collecting vegetation samples
By Marc SimardAirSWOT and AVIRIS-NG flew again together today both performing their now famous flight pirouettes across the skies of the Terrebonne basin. A particularly productive day for AVIRIS-NG, that collected 3 out of 4 Vegetation segments of the Terrebonne West region.

There were 3 teams in the field: the ADCP (JPL only), Vegetation and Island teams.
The JPL team collected several ADCP transects around the 421 sites until it had to return to port as a storm loomed over the region. In addition, the team collected sonar data in between transects using their brand new sonar setup. Although JPL’s Daniel Jensen was not on the water today, he collected in situ field spectra around the AirBnB property conveniently located within the AVIRIS-NG swath to calibrate imagery.

The WQ Team collected water samples as well as reflectance around 421 and Caillou Lake, while the CPRA/ENCOS team collected several surface water samples to coincide with AVIRIS-NG overflight and their own mid-depth samples. The Island Team collected water samples and ADCP data around 421 while AirSWOT and AVIRIS-NG were flying, complementing data collected by the ADCP and Water Quality teams.
The Vegetation Team led by FIU’s Edward Castañeda were at site collected vegetation samples, root and soil cores as well as Liviu’s ‘historical’ 4-meter deep cores at Delta-X’s intensive site 421. At each site they used their new perched-GoPro to characterize subplot representativeness.
