Water column nutrients and chlorophyll a concentrations in oil impacted salt marshes on Chandeleur Islands, July, 2015 through February, 2016

Water column nutrients were measured during a project to investigate sediment denitrification and nitrogen cycling processes. Water samples were filtered through GF/F filters in the field and stored on ice in the dark prior to being frozen at -20 0C within 8 hrs of collection. Data were collected seasonally from July 2015 to February 2016.
