Gulf of Alaska Shelf and Slope Iron and Nitrate Data, Copper River Region, 2010

These are data from cruises carried out in April, May and July 2010 from the Copper River (AK) mouth to beyond the shelf break, approximately 150 km from shore. The focus of the dataset is the iron (Fe) data, intended to help infer the processes controlling concentrations of Fe. The data include concentrations of total dissolvable Fe (TDFe), dissolved Fe (dFe), nitrate, and salinity, temperature and fluorescence data (CTD) as background. This also includes sea surface height deviation data for a two month interval when a Yakutat eddy passed by the sampling site. Also included is a simple 1-dimensional numerical model used to simulate the the April DFe data assuming a DFe flux from shelf sediments, horizontal transport by eddy diffusion, and removal by scavenging. Data from eight model simulations are also included.
