Oceanographic Monitoring

Parks monitored: Glacier Bay

  • Program
  • Reports &
  • Original Source Data



Regular collection of physical oceanographic parameters has taken place in Glacier Bay since 1993. Over time the frequency of measurements has occasionally been amended and staff have turned over. But a solid continuous data series taken using consistent methods, locations, and equipment has been collected. It is made available for direct downloading on this website.

The purpose of this sampling is to compile a dataset of oceanographic conditions from Glacier Bay that can be used to 1) better understand seasonal and interannual changes in the local and regional oceanographic dynamics and 2) better understand spatial and temporal variation in the abundance patterns of marine organisms including phytoplankton, zooplankton, marine invertebrates, fishes, mammals and seabirds. Measured and derived parameters that comprise this dataset include temperature, salinity, stratification, photosynthetically active radiation (PAR), optical backscatterance (OBS; turbidity), chlorophyll fluorescence, and dissolved oxygen.
