Multispectral ASV measurement datasets

Summary

Scientists tested a low-cost robotic boat equipped with light sensors to detect both harmful algae and tiny plastic particles (microplastics) floating in water. This matters because both algae blooms and microplastics can end up in the water we drink or the seafood we eat, and cheaper monitoring tools could help catch contamination earlier. Note that this release is just the raw data and lab test files, it doesn't yet include the actual findings on how well the technology worked.

Field and laboratory measurements from a low-cost autonomous surface vehicle carrying a three-wavelength active optical sensor, used to compute an Algal Growth Index (AGI) and a polyethylene-responsive scattering index (MPI). Contents: night survey (15 January 2026, Coyote Point, San Mateo CA), day survey (18 January 2026, same site), 93 laboratory calibration trial files, and a NOAA NCEI Marine Microplastics extract. This archive holds data only. The analysis code is at https://github.com/dhruvyadati/multispectral_asv_pub
