    "descript": "This portion of the data release presents sediment deposition in the estuary as measured using rod surface elevation tables (RSETs) at fifteen locations throughout the Elwha River estuary, Washington, from August 2011 to June 2014 (no associated USGS Field Activities numbers because data were collected predominantly by biologists from the Lower Elwha Klallam Tribe). The locations of the RSETs were determined with a hand-held global positioning system (GPS). We measured sediment deposition from 2011 to 2013 using the RSET table and pins at 36 points around each RSET. Because of extensive sediment deposition in the estuary, we needed to modify our methodology in 2014. We fabricated a new attachment for the RSET base that consisted of a 30 cm horizontal measuring rod and level, which replaced the RSET table. We leveled the rod with respect to the RSET receiver and measured the distance from the end of the rod to the sediment surface at six locations around the center point using a weighted line. The two methods were calibrated so that measurements were comparable. Measurements were taken approximately every two months in 2011 and 2012 and before and after the rainy and freshet (snowmelt) seasons in 2013 and 2014. The sediment deposition data are provided in a comma-delimited spreadsheet (.csv).",

Distributions are records of substrate characteristics based on visual or photographic inspection or on analysis of samples and cores, and they also include interpretive maps classifying areas on the basis of combinations of observations, hydrodynamic models, or geological models. Assessments include evaluations of present ecological or economic values of substrate distributions, drivers of substrate change, and functions of substrates. Predictions are the results of models or projections of future substrate distributions, values, or ecological impacts, including predicted substrate changes due to natural and human forces including erosion, accretion, sea-level change, extraction, trawling, or other factors; and they are the results of scenario-based models of substrate changes on ecological or economic values under different management strategies or other human alterations."
