SBIR-funded deep-sea methane spectrometer successfully undergoes field testing

NOAA Pacific Marine Environmental Lab, University of Washington, and OptoKnowledge Systems, Inc. (OKSI) successfully conducted the first deep water test of a new methane analyzer. This instrument can collect data that will improve scientists’ understanding of carbon cycling, greenhouse gasses, and sub-seafloor chemosynthetic reactions. The methane analyzer was developed by OKSI with initial funding from the NOAA SBIR Program and has since transformed into a Phase III collaboration. Read the full story

Eruption highlights how NOAA technological innovation powers public safety, economic development, and scientific discovery

When a volcano in the South Pacific Ocean erupted in January 2022, NOAA researchers were well-equipped to study the multi-hazard event by sky and by sea. Key technologies and strategic partnerships made it possible for NOAA to issue warnings that saved lives around the world, while also collecting scientific data that will improve forecasting models and disaster response for future events.

Four Channel Cavity Ringdown NOy Detector

The instrument has lower power, size, weight, and vacuum requirements than a chemiluminescence-based instrument while approaching its sensitivity, precision and time response. In the NOy CRDS instrument of the present invention, NOy and its components are converted into NO2 by thermal decomposition (TD) in a fused silica inlet (henceforth referred to as quartz, following convention), followed by the addition of ozone to convert NO to NO2. NO2 is then measured using a cavity ring-down spectroscopy instrument, utilizing a 405 nm laser. The device may comprise four parallel channels, each driven by the same laser, to measure NO, NO2, NOy and O3, respectively, such that overall NOy may be measured, as well as its components NO, NO2, as well as ozone (O3).

Sub-Surface Automated Dual Water Sampler (SAS)

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!
