AK - TCarta Awarded NOAA Grant to Enhance Satellite Derived Bathymetry Technology in Alaskan Waters

TCarta Marine, a global provider of space-based hydrospatial solutions, has been awarded a Small Business Innovation Research (SBIR) Phase II grant from the National Oceanic and Atmospheric Administration (NOAA).

The research focuses on enhancing Satellite Derived Bathymetry technology for application in the coastal waters of Alaska.

Satellite Derived Bathymetry (SDB) extracts water depth measurements from multispectral satellite imagery using advanced physics-based algorithms. Traditionally, this technology has yielded the most accurate results in clear, calm waters; however, TCarta has recently taken the lead in expanding SDB applications to more challenging marine environments worldwide.

“With the NOAA SBIR grant, our objective is to explore what SDB can achieve in Alaska’s coastal waters with the expectation of applying our findings to the greater Arctic region,” said TCarta President Kyle Goodrich. “This research will benefit hydrographic surveying, coastal zone management, infrastructure development, and other coastal marine projects at high latitudes.”

Begun in 2020, the NOAA SBIR Phase I research expanded the potential sources of satellite imagery for the Alaskan coast. Winter darkness, floating sea ice, turbulent spring runoff, plankton blooms, and unpredictable tidal variations make it difficult to capture images with the quality necessary for SDB processing. Just a small window of acquisition time exists during the summer, and it varies for different areas along Alaska’s 32,000 miles of coastline.
