We primarily use infrared laser spectroscopic techniques that have been developed for atmospheric sensing as the foundation of our sensors. Utilizing gas extraction technologies coupled to infrared spectrometers, we make dissolved gas measurements in extreme ocean environments: hydrothermal vents, submarine volcanoes, methane seeps, bubble plumes, for and brine pools. We use deep submergence technologies, especially remotely operated vehicles, for both instrument development testing and for analyzing these environments in situ.\u00a0 We are currently developing new, smaller sensor systems using alternative approaches.<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/csllab\/wp-content\/uploads\/sites\/113\/2026\/02\/SAGE-Info-Sheet-2026.png\" alt=\"\" width=\"7650\" height=\"9900\" \/><\/p>\n<p>&nbsp;<\/p>\n\t<h3>Funding Agencies<\/h3>\n<p>The NOAA Office of Ocean Exploration and Research, the National Science Ocean Technology and Interdisciplinary Coordination and the Woods Hole Oceanographic Institution funded this project.<\/p>\n<p><img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/csllab\/wp-content\/uploads\/sites\/113\/2021\/05\/nsf_logo_f_ba321daf-8607-41d7-94bc-1db6039d7893.jpg\" alt=\"\" width=\"160\" height=\"100\" \/><img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/csllab\/wp-content\/uploads\/sites\/113\/2021\/05\/download.png\" alt=\"\" width=\"86\" height=\"85\" \/><\/p>\n<p><img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/csllab\/wp-content\/uploads\/sites\/113\/2021\/05\/QN3ytzK6_400x400.png\" alt=\"\" width=\"81\" height=\"81\" \/><\/p>\n\t<h3>Partners\/Collaborators<\/h3>\n<p>This is a collaboration with\u00a0S.
