FIELD TRIP

We will spend one workshop day at Bruneau Dunes State Park, looking at and discussing field data collection. The goal of this field trip is to discuss, in detail, exactly where and how instruments are set up for optimal in situ measurements. The many nuanced considerations about how terrestrial field studies are collected will feed into the following day’s discussions about selecting/setting up an observation site, instrument accommodation, and operations, etc.
