BioBase EcoSound does Seagrass, Kelp, and Tides Too!

Although BioBase EcoSound was originally developed for aquatic vegetation mapping in inland lakes, users along both US Coasts have helped us diversify its toolbox to now be a powerful coastal habitat mapping tool as well!

One of the biggest challenges of mapping coastal habitats is their tidal influence with depths changing harmonically based on the moon phase and other factors.  Fortunately, however, widespread tide stations and large public databases of tide predictions allow for accurate and precise offsets to georeferenced and time-stamped sonar logs from Lowrance HDS or Elite units uploaded to BioBase EcoSound.  BioBase EcoSound immediately queries the nearest tide station to your upload (up to 75 km) and adjusts your depth and seagrass or kelp biovolume to the Mean Lower Low Water (MLLW) datum every 5 minutes.  Tidal statistics (Avg., start, stop, high, low,) are archived in your account for each trip.

Virtual Eyes to See Aquatic Resources in 3D

One of the biggest challenges to understanding aquatic resources are the optical properties of water and an inability of our human eyes to see the complex world that lurks beneath the surface.  In contrast, when “aeroplanes” (that’s what they were called in the Wright Brother’s days) first took flight in the early 1900’s and pilots figured out how to fix cameras to the belly to take aerial photos, it opened up a new world of exploration for biologists and foresters studying terrestrial landscapes.  The term “landscape” got a whole new meaning.
