  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.
