Deployment: FK141215

2014-12-15 - 2014-12-21 Challenger Deep, Mariana Trench Platform:R/V Falkor (vessel)

Description

During this cruise the Leggo lander was deployed multiple times and drops 1 and 3 recovered seawater samples that were analyzed. Additional details can be found at: https://schmidtocean.org/cruise/expanding-mariana-trench-perspectives/ and https://scripps.ucsd.edu/labs/dbartlett/contact/challenger-deep-cruise-2014/.
