Frequently-anticipated questions:

What does this data set describe?

Title:
Appendix 1. Full listing of all samples collected for this project.
Abstract:
This spreadsheet provides a full listing of all samples collected during our study of submarine groundwater discharge in KAHO park. Information on location, date and time of collection, salinity, radium isotope activities, and nutrient concentrations are given. The information in this table was used to calculate site-specific fluxes of groundwater and nutrients into the coastal ocean using a simple mass-balance approach.
Supplemental_Information:
Samples were collected in December 2003, November 2005 and April 2006 from the coastal ocean, beach pits, three park observation wells, anchialine pools, fishponds, and Honokohau Harbor. The activities of two isotopes of radium commonly used as natural groundwater tracers (223Ra and 224Ra), salinity, and nutrient concentrations were measured.
