Creation of Glacier Bay Oceanographic Information Products Defined in Protocol OC-2010.1 Using Legac

The Southeast Alaska Inventory and Monitoring Network (SEAN) embarked on a project in summer 2010 to build the detailed physical oceanography information products specified in its formal protocol OC-2010.1 based on historic legacy data collected by USGS in Glacier Bay National Park and Preserve. The intention was to make a consistent and comparable data set covering 1993 through the present. The project completed successfully and these products are accessible at http: //science.nature.nps.gov/im/units/sean/OC_Main.aspx (accessed on 29 October 2010). This paper documents the methods used to collect and process legacy data in order to create the detailed products. It explains how the required quality control levels were obtained. Exceptional data circumstances for each product are also listed. An appendix compares overall differences between original legacy values and those obtained through the project
