This child data release includes hyperspectral and RGB images acquired from an Unmanned Aircraft System (UAS) during an experiment performed at the USGS Columbia Environmental Research Center, near Columbia, Missouri, on April 2, 2019. The purpose of the experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) tracer from various types of remotely sensed data in water with varying levels of turbidity. Whereas previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, the Missouri River is much more turbid and the reflectance signal associated with the sediment-laden water could obscure that related to the presence and amount...

Data include Rhodamine WT dye concentrations measured every 3 or 10 minutes by means of Turner Designs C-3 and C-6 fluorometers with internal dataloggers at three fixed locations on the Des Plaines River (DPR) (DP-1, DP-2, and DP-3); in three groundwater monitoring wells (ACL-1, WP10-85, and WP9-275); and at two fixed locations on the Chicago Sanitary and Ship Canal (CSSC) (SC-1 and SC-2) (see included Google Earth file AllDeployments_Locations.kmz). The detection limit for these fluorometers is reported to be 0.01 parts per billion (ppb). However, the fluorometer readings were affected by turbidity, and readings of less than about 1.0 part per billion (ppb) were considered to have been influenced by turbidity and...

Tracking changes in bulk electrical conductivity (EC) during tracer tests in saturated sediments allows for direct observation of both mobile and less-mobile pore space exchange dynamics. Electrode arrays made up of four stainless steel rods (insulated with the exception of exposed 0.5 cm tips) were installed vertically at depths of interest and apparent electrical resistivity data (the inverse of bulk EC) were collected using a Wenner configuration with an AGI SuperSting R8 meter. The Bulk EC data are described and listed within the files below. Controlled, downward flow experiments were conducted in Dual-domain porosity apparatus (DDPA). Downward flow rates ranged from 1.2 to 1.4 m/d in DDPA1 and at 1 m/d, 3 m/d,...

Two survey boats equipped with differential Global Positioning System (GPS) receivers and Turner Designs C3 submersible fluorometers were used to survey the spatial distribution of the Rhodamine WT dye in the Des Plaines River downstream of the Brandon Road Lock and Dam (BRLD) near Rockdale, Ilinois. Mapping of the dye plume commenced after the lock chamber at BRLD was dyed with 4 liters of Rhodamine WT dye during a routine filling procedure. Measurements of dye concentration downstream collected by these survey boats capture the leakage of dyed water from the lock, the pulse of dyed water exiting the lock during routine emptying of the lock, and the mixing of the dyed water downstream during a 17-minute flushing...

These data were collected during a dye tracing study of the lower Des Plaines River and lower Chicago Sanitary and Ship Canal (CSSC) in November 2011 by the U.S. Geological Survey. The study attempted to identify potential inflows of Des Plaines River water through the fractured bedrock that separates the two water bodies. Data include Rhodamine WT dye concentrations measured every 3 or 10 minutes by means of Turner Designs C3 and C6 fluorometers with internal dataloggers at three fixed locations on the Des Plaines River, in three groundwater monitoring wells, at two fixed locations on the CSSC, and from a mobile vessel in the CSSC.

Five Turner Designs C3 submersible fluorometers were deployed in the Des Plaines River downstream of the Brandon Road Lock and Dam (BRLD) near Rockdale, IL to measure Rhodamine WT dye concentrations during a U.S. Geological Survey dye study conducted on October 20-21, 2015. The lock chamber at BRLD was dyed with 4 liters of Rhodamine WT dye during a routine filling procedure. Measurements of dye concentration downstream collected by these instruments capture the leakage of dyed water from the lock, the pulse of dyed water exiting the lock during routine emptying of the lock, and the mixing of the dyed water downstream during a 17-minute flushing operation of the lock. The fluorometers were installed on both sides...

A boat equipped with a differential Global Positioning System (GPS) receiver (Hemisphere Crescent A100 Smart Antenna) and a Turner Designs C3 submersible fluorometer was used to survey the spatial distribution of the Rhodamine WT dye in the Chicago Sanitary and Ship Canal (CSSC) throughout the study area. The fluorometer was installed in a fixed, downlooking orientation approximately 1 foot below the water surface. Fluorometer readings were taken at a frequency of 1 per second. Data were acquired on a personal computer running the Turner Designs C-FINS software extension for ArcGIS 10. This data acquisition software allows the C3 data to be georeferenced and plotted in real time as color-coded concentrations on...

Quantification of mobile/less-mobile porosity dynamics at the sediment/water interface is critical to predicting contaminant storage, release, and transformation processes. Zones in groundwater flow-through lakes where lake water recharges the aquifer can strongly control aquifer water quality. Less-mobile porosity has previously been characterized in aquifers using flow path scale (10's of m+) tracer injections which are analyzed using numerical models. Methodology was recently developed to couple geoelectric measurements (bulk electrical conductivity, EC), which are directly sensitive to less-mobile ionic tracer exchange processes, with pumped fluid EC tracer data over time. If the fluid EC concentration history...

When water is pumped slowly from saturated sediment-water inteface sediments, the more highly connected, mobile porosity domain is prefferentially sampled, compared to less-mobile pore spaces. Changes in fluid electrical conductivity (EC) during controlled downward ionic tracer injections into interface sediments can be assumed to represent mobile porosity dynamics, which are therefore distinguished from less-mobile porosity dynamics that is measured using bulk EC geoelectrical methods. Fluid EC samples were drawn at flow rates similar to tracer injection rates to prevent inducing preferential flow. The data were collected using a stainless steel tube with slits cut into the bottom (USGS MINIPOINT style) connected...

A Turner Designs C3 submersible fluorometer was deployed in the Brandon Road Lock chamber (BRLD) near Rockdale, Illinois, to measure Rhodamine WT dye concentrations during a U.S. Geological Survey dye study conducted on October 20, 2015. The lock chamber at BRLD was dyed with 4 liters of Rhodamine WT dye during a routine filling procedure. Measurements of dye concentration profiles were collected at 15 stations in the lock chamber and capture the three-dimensional distribution of the dye in the chamber after filling, after the lock was emptied, and after a 17-minute flushing operation of the lock. A series of five taglines and rope and pulley systems were used to position the fluorometer at each station to avoid...

An Insitu Level Troll 500 was deployed in the Brandon Road Lock chamber (BRLD) near Rockdale, Illinois between 12:09 Central Daylight Time (CDT) on October 19, 2015 and 14:57 CDT October 21, 2015 to monitor water-surface elevation in the lock chamber during a U.S. Geological Survey dye study conducted on October 20, 2015. The duration of the deployment included a day prior to and a day following the dye study to capture the lock operations leading up to and following the dye study. The instrument was deployed within conduit placed inside the ladder well near the 500-foot station on the right wall of the lock chamber (when looking downstream). At the time of deployment, the Level Troll was calibrated to the water...
