Sediment trap data from Lake Peters and Lake Schrader, Arctic National Wildlife Refuge, Alaska, 2015-2017
Throughout 2015-2017, sediment traps were deployed in Lakes Peters and Schrader to measure the rate of deposition and collect suspended sediments in the lakes. In 2015, three pairs of static (i.e., non-automated) traps with different aspect ratios (different collection-tube heights but same collecti...

Throughout 2015-2017, sediment traps were deployed in Lakes Peters and Schrader to measure the rate of deposition and collect suspended sediments in the lakes.

In May-August 2016, one static trap was deployed in Lake Peters, two sets in Lake Schrader, and one set in a small pond on the southwestern edge of Lake Schrader ("Schrader Pond").
