AdVENTure Into the Deep Dive into cold seep ecosystems! Students use real bathymetric data to explore chemosynthesis and predict where new deep-sea seep communities might exist.Students explore cold seeps—deep-sea habitats where methane fuels life without sunlight—and learn how chemosynthesis supports unique food webs built on methanotrophic bacteria. Using real-world data, they analyze relationships between depth, vent location, and bubble activity, building graphs to identify ecological patterns. The lesson culminates in a creative challenge: students apply their findings and bathymetric knowledge to hypothesize a new location where a cold seep community, complete with tubeworms, could exist. The activity builds skills in data analysis, systems thinking, and evidence-based prediction while deepening understanding of deep-sea ecosystems.Cover image from Deep Ocean Education Project (https://deepoceaneducation.org/resources/astoria-canyon-bubbles-and-fauna/) Topics Bathymetry, Earth Science AuthorsJenna Forslund & Sam Loftus Teacher ResourcesLesson PlanInteractive map of seafloor featuresGMRT websiteGMRT Map Tool TutorialCER Graphic OrganizerGraph Keys Student ResourcesInteractive map of seafloor featuresGMRT website Additional ResourcesSEAFLEAs map – Interactive map showing known methane seepsBackground ReadingQuantitatively Monitoring Bubble-Flow at a Seep Site Offshore Oregon: Field Trials and Methodological Advances for Parallel Optical and Hydroacoustical MeasurementsDistribution of Methane Plumes on Cascadia Margin and Implications for the Landward Limit of Methane Hydrate Stability.Additional Educational Materialhttps://oceanexplorer.noaa.gov/edu/themes/cold-seeps/welcome.html Next Generation Science StandardsCrosscutting ConceptsCause and effectPatterns Core IdeasESS2.E: BiogeologyLS2.A: Interdependent Relationships in EcosystemsPracticesAnalyzing and Interpreting DataEngaging in Argument from Evidence Ocean Literacy Fundamental Concepts5: The ocean supports a great diversity of life and ecosystems.
