Water and algal chemistry measurements collected from the National Park Service's National Park of American Samoa (NPS-NPSA) Ofu Island unit
July 14, 2025
Geochemical analysis of coastal springs and possible source waters were conducted in the National Park Service's National Park of American Samoa (NPS-NPSA) Ofu Island unit. Water samples were analyzed for dissolved nutrients, nitrate isotopes (delta-18-O and delta-15-N). Algae samples were collected and analyzed for delta-15-N and delta-13-C values.

Land-based nutrient flux to a fringing reef: Insights from Ofu Island, American Samoa Land-based nutrient flux to a fringing reef: Insights from Ofu Island, American Samoa
Submarine groundwater discharge (SGD) is a critical driver of nutrient transport in coral reef ecosystems, shaping water quality, primary productivity, and overall reef health. This study quantifies SGD fluxes and associated nutrient dynamics in two reef flat pools within the Ofu Unit of the National Park of American Samoa: Papaloloa and Fatuana. A multi-method approach integrating...
