Initiated in 1993, the Glacier Bay hydrographic survey archives represent one of the longest-running oceanographic datasets in Alaska waters. This updated document—the first formal protocol revision since the initial (2010) version—describes the field methods and data handling procedures required to ensure an uninterrupted and consistent sampling program exhibiting solid collection, quality assurance, archiving, and dissemination procedures. The products generated will enable future analyses to better interpret observed changes in the marine physical environment and better understand how they impact the abundant marine life found within Glacier Bay. Nine field surveys are scheduled for each year: comprehensive surveys in midwinter and midsummer with occupation of all 22 standard stations, and seven monthly surveys between March and October with occupations of eight representative core stations. Water column profiles of the following parameters constitute the measurements for all surveys: water temperature, salinity, photosynthetically active radiation (PAR), optical backscatterance (OBS—turbidity), dissolved oxygen (DO) concentration, and chlorophyll-a fluorescence. The outcome of this program consists of data and information products. Their specific content and detailed methods for building them are rigorously defined.
