In 1954, Dr. Henry M. Stommel initiated Hydrostation S - a deep-water research mooring - to gather information on the physical nature of the ocean in an effort to address fundamental questions about currents and air-sea gas exchange. Since then, scientists have visited the station biweekly, resulting in the world's longest-running time-series for physical oceanographic data, including temperature, salinity, and dissolved oxygen measurements.

Data from Hydrostation S have been used by scientists around the world for research on a variety of topics, including:

  • Temporal variations in dissolved nutrient stocks
  • Phytoplankton population dynamics, seasonal cycles, and blooms
  • Variability in oceanic CO2 and biogeochemical cycles
  • Microbial genomics and dynamics
  • Inter-annual and decadal-scale variability of the North Atlantic Ocean and Sargasso Sea
  • Heat, salinity, and carbon budgets of the open ocean
  • Paleoclimate reconstructions
