Sonar Depth Measurements at Lakes on the Alaskan Inner Artic Coastal Plain, July 2017
This dataset provides discrete depth point measurements, each collected as part of a transect at 19 lakes on Alaska's Inner Arctic Coastal Plain. Lakes at which measurements were collected had to be large enough for a floatplane to land on (i.e. > ~1 km2 lake surface area), as data were coll...

This dataset provides discrete depth point measurements, each collected as part of a transect at 19 lakes on Alaska's Inner Arctic Coastal Plain.

Depth points were measured by the sonar recorder every second and are vertically accurate to 0.03 m. Erroneous points have been manually removed.
