Description:

Abstract:

This dataset shows the variability in conductivity of limestone units that comprise the Northern Guam Lens Aquifer (NGLA).

Purpose:

Estimating hydraulic properties from tidal attenuation in the Northern Guam Lens Aquifer (NGLA),

Supplemental_Information:

The authors calculated conductivity values using SUTRA modeling.
