Upper Mississippi River water and bigheaded carp otolith chemistry data

Data set includes water Sr:Ca, Ba:Ca, and δ18O for the Upper Mississippi River and tributaries and otolith Sr:Ca, Ba:Ca, and δ18O data from bigheaded carp collected in pools 19-21 of the Upper Mississippi River. Abstract from manuscript: Knowledge of environments used during early life history and movement patterns of Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp...

Study of Off- Channel Waterbodies in the Middle Mississippi River

Backwaters and other floodplain waterbodies are rare within the Middle Mississippi River. The lack of these habitats likely influences water quality, nutrient processing, and communities of organisms. In early 2016 a major flood event breached two levees south of Cape Girardeau, MO resulting in the creation of two new backwaters. Water quality, metabolic rate, and fish community data were...

Investigating the mixing efficiencies of liquid-to-liquid chemical injection manifolds for aquatic invasive species management:Data

Spreadsheet includes data that were used to evaluate the mixing efficiencies of liquid-to-liquid chemical injection manifolds. Specifically, piping designs were developed to deliver fisheries chemicals (e.g. carbon dioxide) into water to control the movements of invasive bigheaded carps. These data describe mixing time, homogeneity and efficacy of carbon dioxide delivery using various piping...

Sagittaria flooding tolerance experiment data

To assess the flooding tolerance of Sagittaria latifolia and S. rigida, we assessed three levels of timing of inundation (early- [11 June], mid- [12 July], late-season [12 August]), three levels of duration (short [1 day], mid [5 days], long [10 days]), and four levels of depth (reference plant not treated, shallow [5 cm], moderate [20 cm], deep [45 cm]) on survival and productivity of...

Daily calling activity for Pseudacris crucifer at site SC4DAI2 in the St. Croix National Scenic Riverway from 2008 to 2012, as indicated by the results of integrating daily median dB values across 2900 to 3200 Hz and 2100 to 2300 h

To describe calling activity of Pseudacris crucifer in relation to temperature, precipitation, and wetland water levels, we programmed an acoustic recorder (Wildlife Acoustics) to sample seasonal amphibian calls remotely at study site SC4DAI2 in the St. Croix National Scenic Riverway from 2008 to 2012. We programmed the recorder to sample for five minutes at the top of every hour of every day...

Timing of first and last calls and median calling peaks for Pseudacris crucifer, and of the first call for Hyla chrysoscelis/versicolor, at six wetlands in the St. Croix National Scenic Riverway from 2008-2012.

To better understand relations of annual calling phenophases for Pseudacris crucifer, and of the first calls of the season for Hyla chrysoscelis/versicolor, to the timing of the start of the calling season, we compared these dynamics for six wetlands in the St. Croix National Scenic Riverway from 2008 to 2012. We installed an acoustic recorder at each site prior to the start of each calling...

Seasonal median daily water depths for study wetlands in the Tamarac National Wildlife Refuge, the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Research area, and the Upper Mississippi River study area from 2008-2012.

To relate water levels in our study wetlands to temperature, precipitation, wetland water depth, and amphibian calling activity, we installed one pressure logger in the deepest spot we could find in each wetland. Soon after thawing conditions allowed, we drove a plastic pipe (anchor pipe) into the sediments at the deepest location and secured another pipe to it that contained one pressure...

The eight-day interval during which amphibians first called annually at individual study wetlands across four study areas.

To help determine when winter conditions were changing to spring conditions annually in our four study areas, we determined the first eight-day interval (in accordance with the scale limitations of satellite data we used to assess the presence of snow) during which the first amphibian of the season called at each of our study wetlands in those areas. To do this, we examined contour plots of...

Patapsco Shapefiles depicting the valley bottom areas.

The shapefiles depict the valley bottom areas over which HEC-RAS model results were summarized. Valley bottoms were manually delineated in ArcMap by visually interpreting LIDAR terrain models and aerial imagery. Substantial changes in elevation, curvature, and slope were interpreted within the context of their position within the study reach to be channel banks and valley walls. Such areas...

Patuxent Shapefiles depicting the 2D HEC-RAS hydraulic modeling domains

The shapefiles depict the 2D HEC-RAS hydraulic modeling domains used for the simulations described in the associated publication. Model domains were delineated in the HEC-RAS geometry editor to encompass river-valley bottoms and adjacent hillslopes of four river reaches of contrasting contributing area and morphology: Seneca Creek at Dawsonville, MD; Patapsco River at Woodstock, MD; Patuxent...

Patapsco Terrain models

Terrain models representing river channel and terrestrial surface elevations were developed for use in 2D hydraulic modeling with HEC-RAS software. Channel bed elevations were determined from cross-sectional field surveys (Seneca Creek and Patapsco River) or manual corrections of the LIDAR data (Patuxent River and Little Gunpowder Falls) and integrated with the terrestrial LIDAR data.
