Stage data were combined with a rating curve to calculate discharge (Q, m3/s). Monitoring sites included a forested site (F1: stage, T, SSC), a site downstream of a quarry (F2: T, SSC), and a site upstream of the discharge point to the ocean (F3: stage, T, SSC). Grab samples of water for SSC were collected at F1, F2, F3, and some supplemental sites. See Messina and Biggs (2016) and Holst-Rice et al (2016) for details. The data were collected to determine the impacts of human activities on discharge and sediment load to the coast.

Discharge calculated using a rating curve according to Messina and Biggs, 2016, Journal of Hydrology v 538 pp 726-742.; Data Quality Method: Rating curves were developed using observed stage and discharge to calibrate a hydraulic model (see Messina and Biggs 2016). Discharge values were checked against the site downstream (F3) using double mass curve analysis. The stage was adjusted manually (field "Stage.corr.cm") where needed to maintain consistency in the double mass curves. Parameter or Variable: Turbidity (measured); Units: NTU; Observation Category: in situ; Sampling Instrument: Turbidity Meter; Sampling and Analyzing Method: Turbidity meters were installed at F1, F2 (2016 only), and F3 and recorded turbidity every 5-15 minutes. Several different models were used over the course of the project; see Messina and Biggs 2016 for details.; Data Quality Method: Turbidity meters were checked against standards at the beginning and end of deployment periods, and sent to the manufacturer for recalibration at the end of each campaign. Quality flags are "O" = outlier; "B"=bad value, unknown reason", "S"=sunlight artifact. Parameter or Variable: Suspended sediment concentration (measured); Units: mg/L; Observation Category: in situ; Sampling Instrument: Manual grab or autosampler; Sampling and Analyzing Method: Water samples were collected using manual grab with a 1L wide-mouthed bottle, or with an autosampler. SSC was determined using gravimetric methods (see Messina 2016 and Messina and Biggs 2016 for details).; Data Quality Method: Duplicates were run on some samples to check for consistency. asNeeded Metadata are developed, maintained and distributed by NCEI.

NOAA National Centers for Environmental Information custodian bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle. pressure sensor pressure sensor GCMD instruments - In Situ/Laboratory Instruments > Pressure/Height Meters > PRESSURE SENSORS ASFA Thesaurus - pressure sensors http://www4.fao.org/asfa/asfa.htm turbidity sensor turbidity sensor Measures the turbidity of water Turbidity sensors measure the amount of light that is scattered by suspended solids in a liquid, such as water. When the concentration of total suspended solids (TSS) and total dissolved solids (TDS) in a liquid increase, the turbidity also increases.
