Burping wetlands : quantifying greenhouse gas ebullition rates across a range of sediment types and characteristics, water quality variables, and land use
Newson, Jannice; Bragg, Jaylen; Amjad, Hamza; Dyck, Lauren; Komarevich, Selena; Whitfield, Colin; Baulch, Helen; Venkiteswaran, Jason; Casson, Nora; Helmle, Richard; North, Rebecca L. (University of Missouri--Columbia, 2018)Aquatic ecosystems are a source of greenhouse gases (GHG) to the atmosphere. One pathway of this GHG release is ebullition, or bubbling, from aquatic sediments. The contribution of ebullition is often underestimated in ... -
Differences in atmospheric phosphorus deposition amongst rural and urban land use locations in Missouri
Rein, Crystal; Arellano, Sarahi V.; Friesen-Hughes, Karl; King, Ashley; Marten, Alexia; Sanderson, Corey; Venkiteswaran, Jason J.; Baulch, Helen; Casson, Nora J.; Whitfield, Colin J.; North, Rebecca L. (University of Missouri--Columbia., 2022)Atmospheric phosphorus (AP) produced by both anthropogenic and natural processes influences phytoplankton productivity and alters carbon processing in water bodies, resulting in potential impairment and toxic phytoplankton ... -
Does allochthonous disscolved organic matter increase during summer algal bloom conditions in an agricultural reservoir?
Florea, Kyra M.; Bhattacharya, Ruchi; North, Rebecca L. (University of Missouri--Columbia, 2019)Cyanobacterial harmful algal blooms (cyanoHABs) are increasing in frequency worldwide. CyanoHABs can produce toxins (e.g., microcystin), which can be a contaminant in recreational and drinking water reservoirs. Reservoirs ... -
Freezing plants : exploring the effects of freeze thaw cycles on macrophyte phosphorus release
Sauer, Matthew; Ahmed, Osama; Leathers, Jeremy; Nugent, Katy; Prentice, Tyler; Baulch, Helen; Casson, Nora; Venkiteswaran, Jason; Whitfield, Colin; North, Rebecca L. (University of Missouri--Columbia., 2017)Every year following the cold winter freeze comes the spring thaw, and with it comes an influx of nutrients that can cause eutrophication problems; even in high nutrient systems. We identified a potential source of nutrients ... -
Load, not loading: External nutrient loading impact on cyanobacteria and cyanotoxins
Gallagher, Owen; North, Rebecca L. (University of Missouri--Columbia, 2021)Eutrophication is the process in which excessive nutrients enter a body of water resulting in a rapid growth in population and density of phytoplankton. One type of phytoplankton made more concentrated during eutrophication ... -
Quantifying greenhouse gas ebullition rates across varying land uses, sediment types, and water temperatures in wetland systems
Bragg, Jaylen; North, Rebecca L. (University of Missouri--Columbia, 2021)Around the world, wetlands and other aquatic ecosystems release greenhouse gases (GHG) into the atmosphere. GHGs escape from these systems through the process of ebullition -- or bubbles being released from the aquatic ... -
Stagnate summers : climate induced changes in physical mixing parameters in Missouri reservoirs
Kimbell, Cody; Jones, John R. (John Richard), 1947-; Obrecht, Daniel; North, Rebecca L. (University of Missouri--Columbia, 2017)Lakes and reservoirs are important environmental sentinels for climate change. As air temperatures rise so do the temperatures of these water bodies affecting their physical, chemical, and biological properties. Being used ...
