| Methods: |
Water samples were collected
at depths 0,1,3,5,8,12,16 meters with a Van Dorn. Water was
filtered in the field using 47mm .045 um millipore HAE filters.
Filterd water was kept at 4C in amber bottles until being run on
an ALP chem auto analyzer using methods for Phosphorus, ammonia
and nitrate/nitrite. Due to an unsatifactory high detection
limit with the autoanalyzer ammonia chemistry was done by hand
using Standard methods.
