| Methods: |
Water samples were collected at depths 0,1,3,5,8,12,16 meters with a Van Dorn. The water was
returned to the lab where it was filtered through a 25mm GFF glass fiber filter Cation samples are
stored in 60 ml HDPE bottles and are preserved with 50 ul Ultrex HCL. Anion samples are stored in 30
HDPE bottles.
Cation samples are run on a Perkin Elmer atomic absorption spectrophotometer. Lanthanum
cloride was added to 10% prior to running calcium samples.
Anions samples were run on a Dionex liquid chromatographer using fast sep column
