Elwha River coastal tripod time-series datasets (2013-2014), containing gravity-flow data from 9 Mar 2014

Abstract

This dataset consists of a Matlab data file, 'ElwhaGF20132014.mat', and a text metadata file, 'MetadataElwhaGF20132014.txt.' These data were collected by PIs Andrea Ogston and Chuck Nittrouer, graduate student Emily Eidam, and the UW Sediment Dynamics lab from November 2013 to April 2014 on the Elwha Delta. The data are time-series measurements from acoustic, optical, and peripheral sensors deployed on two bottom-boundary-layer tripod frames deployed at ~14 m and ~23 m water depth within 1 km of the Elwha River mouth. Measurements were collected as part of an ongoing effort to document sediment gravity flows generated during the removal of two hydroelectric dams from the river (a large-scale inter-agency restoration project conducted between 2011 and 2014). Data from prior instrument deployments were reported in Eidam et al., 2016 (see citation below); data from this deployment are reported in a new paper currently in prep (as of Dec 2017). These data were collected under NSF grant 0960788.

The Matlab file is divided into structures by instrument. The supporting metadata file gives variable descriptions and units.
