Support Open-Access Coastal Science & Education
Translating authentic coastal field science into open-access digital labs and turnkey educator resource bundles.
Powering the 2027 Field Season & Classroom Launch
Thanks to early seed supporters, our baseline vessel operations aboard R/V HMS Buttercup are secured.
Every gift today directly accelerates our 2027 launch—underwriting cloud GIS hosting (ArcGIS StoryMaps), in-situ water testing supplies, and the deployment of our Open-Access STEM Curriculum and DIY Lab Bundles to public school classrooms and homeschool families at zero cost to educators.
