Sub-Surface Automated Dual Water Sampler (SAS)Designed by researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the University of Miami to help scientists study water chemistry on shallow reef habitats. Explore the SAS website, use it to guide you in building and using your own water samplers, embrace the maker movement, and improve on our design. If you are a teacher, there are free lesson plans to download that include labs and activities related to science, technology, and engineering. Check out the NOAA SAS website and please use the SAS to learn about and explore our oceans!
Opuhala was the ancient Hawaiian goddess of corals and spiny creatures. The National Oceanic and Atmospheric Administration (NOAA) Coral Health & Monitoring Program has chosen this name to represent the project to study the influence of fluctuating sea temperatures on the growth and health of corals around the world, and also to compare the in situ data with satellite-measured data in an effort to improve satellite algorithms. Three different types of coral reefs: fringing, barrier, and atolls will be monitored at 5m, 10m and 15m depths, where appropriate. The sea temperature sensor developed for the Opuhala project has been developed with low cost in mind because of the diversity of sites that will measure sea temperature in this global project.
