Marine Water Quality
Ambient Water Quality Monitoring in Harbors and Shipping Lanes
Overview
The goal of this effort is to provide reliable ambient water quality information on marine areas where there is a concentration of marine transportation activity. Scientific evaluation of these data provides information to protect human health and the environment. Since 2015, DEC has monitored select ports and waterways for a suite of water quality parameters including total and dissolved metals (Copper, Nickel and Zinc), ammonia as nitrogen, bacteria (fecal coliform and enterococci) and physical parameters of: dissolved oxygen, pH, temperature, salinity and turbidity. Water quality sampling is occurring at 164 sample sites, in 19 Alaskan ports and in 30 high traffic shipping lanes.
Data from this project presented below includes a raw data download, interactive summary maps/dashboards, and PDF summary reports.
