Methods and protocols used in the collection of this data package

Description:

Experimental Design

This site is part of the ongoing APEX long-term experiments, monitoring effects of permafrost thaw.

Methods

FIELD: Data set contains a variety of environmental measurements collected in the field, as well as various categorical assignments of plots. Measured variables include active layer thickness measured with a tile probe, soil moisture measured with a soil moisture meter, soil temperature measured with a temp probe. LAB: Values for gas fluxes borrowed from gas flux master sheet, with details elsewhere (see BNZ_Metadata_Beta_Flux).
