The original CALM protocols, published in 1996 as part of the ITEX Manual, are:

Active Layer Monitoring
     includes discussion on sampling designs, probing, frost tubes and soil temperature measurements.

Soil Moisture
     including stationary and spatial measurements using gravimetric method and Vitel soil moisture probes.

Ground Subsidence and Heave

Site Location
     reporting geographic coordinates of CALM sites
