With partial support from the Rasmuson Foundation, the PWS Science Center will be purchasing a Seal Analytical AutoAnalyzer3 (AA3) in autumn 2015. The AA3 is an automated segmented flow analyzer with auto-sampling, processing, and measurement capabilities; it will initially be set up to measure nitrate (commonly the limiting nutrient in the coastal ocean), and has the capability to add multiple other nutrients (phosphate and silicate). When operational, the AA3 will be used to measure nutrients in water samples collected during ongoing Science Center monitoring programs such as Gulf Watch Alaska.
