NOS Alaska Historical Circulation Survey Data Restoration: Cook Inlet (1973-1975), Prince William Sound (1976-1978), Icy Bay (1979), and Southeast Alaska (1984).

摘要

The purpose of this report is to document the restoration of the National Ocean Service (NOS) historical circulation survey data in Cook Inlet (1973-1975), Prince William Sound (1976-1978), Icy Bay (1979), and Southeast Alaska (1984). Previous computer programs developed for Delaware River and Bay circulation survey data (2006) were used to analyze conductivity-temperature and current (CT/Current) data (Richardson and Schmalz, 2006). There were no CTD profile data available. Based on plots of salinity, temperature, current speed and direction at CT/Current moorings, temperature, salinity and current speed and direction data quality were assessed and indicated in the dataset tables. Meteorological data (sea level atmospheric pressure, air temperature, and wind speed and wind direction) were either not collected or not considered due to data issues. This report is meant to serve as a supplement to the Cook Inlet circulation survey report and to serve as the circulation survey report for Prince William Sound, Icy Bay, and Southeast Alaska. While no formal quality control has been performed, the data processing algorithms, which may be used to accomplish this are described. Investigators may use these or other approaches for further quality control. Each estuary is next presented in a separate chapter, including description of data inventories of both raw and processed data files. Discussion of the CT/current data is followed by regional oceanographic considerations. Major data preservation and data use issues are then addressed. In conclusion, an overall summary is provided along with recommendations for additional data analysis tasks.
