    "descript": "Time-series data of velocity, pressure, turbidity, conductivity, and temperature were collected near the mouth of the Elwha River, Washington, USA, from December 2010 through October 2014, for the Department of Interior\u2019s\u00a0Elwha River Restoration project.\u00a0As part of this project, the U.S. Geological Survey studied the effects of renewed sediment supplies on the coastal ecosystems before, during, and following the removal of two dams, Elwha and Glines Canyon, from the Elwha River.\u00a0Removal of the dams reintroduced sediment stored in the reservoirs to the river, and the river moved much of this sediment to the coast.  Several benthic tripods were instrumented with oceanographic sensors\u00a0to collect the time-series data. Initial deployment in December 2010 consisted of one tripod about 1 km east of the Elwha River mouth (Tripod A). In March of 2011, an identical tripod (Tripod B) was placed about 1 km west of the river mouth.\u00a0A mooring was added to the western site in July 2012 to measure turbidity and conductivity near the surface.\u00a0\u00a0A third tripod was placed in deeper water (50 m) directly offshore of the river mouth in an attempt to characterize sediment gravity flows near the seafloor if they occurred (Tripod C).\u00a0Exceptional sedimentation was observed near the original tripod site A during the winter of 2013-2014. As a result, the tripod was relocated further east in April 2013 and renamed Tripod D.  Please check metadata and instrument information carefully for applicable time periods of specific data, as individual instrument deployment times and duration of the time series vary.  The naming convention for the NetCDF files included in this release is a 12-character alphanumeric code (ELWYYJKLNNXX.nc) where:  ELW is a 3-digit alphabetic-code for this experiment located at the mouth of the Elwha River YY is the 2-digit year at the time of deployment J is the location with respect to the river mouth [A, East (December 2010 to April 2013); B, West; C, Offshore; D, East (April 2013 to March 2014)] K is the deployment number (1-9; beginning and ending dates of each deployment are given below) L is the instrument package type (T, tripod; M, surface mooring) NN indicates the position of instrument on the surface mooring (01, nearest the surface; NN increases with depth) XX denotes the instrument or data type (wh, RDInstruments ADCP current data; wv, RDInstruments ADCP derived wave parameters; nx, Falmouth Scientific NXIC CTD; aq, Aquatec Aqualogger OBS; bl, RBR, Ltd CTD; sc, SeaBird Electonics SBE16+ CT)  Some derived parameters are included in these data.

Distributions are records of currents, physical properties, or biogeochemical water properties, often based on shipboard surveys or coastal monitoring programs, and maps of currents or water property climatology, which indicate the expected locations of features under present conditions or apply a classification structure like that of CMECS. Assessments are data that provide information about the ecological or economic values, impacts, drivers, connections, or functions of water column features in their present distributions. Predictions are the results of models projecting future changes to currents or other persistent oceanographic features (for example, clines, stratification, connectivity, linkages, and zones of separation) due to climate change, ice-cap melt, and changing freshwater inputs; models predicting the ecological or economic impacts of these changes; and scenario-testing models comparing ecological or economic outcomes of different management actions."
