Improved Aquatic Stream Passage, Elise Emil, Jess Wilson

Community Engaged Research Reports

The Androscoggin Valley Soil and Water Conservation District (AVSWCD) expressed a need for the research and development of a semi-quantitative metric that can be used to determine priority stream barriers (eg. culverts; dams) to remove in Androscoggin and Sagadahoc Counties in Maine. In conjunction with a representative from the US Fish and Wildlife Service, Alex Abbott, the AVSWCD provided data about various stream sites within these two counties that had been recently surveyed. This included information about the aquatic ecological features of various stream habitats containing barriers and information about the physical characteristics of the barriers themselves.

Suspended Sediment Size Distribution In A Numerical Sediment Transport Model For A Partially-Mixed Estaury, Danielle Tarpley, Courtney Harris, Carl Friedrichs

Presentations

Particle settling velocity impacts the transport of suspended sediment to the first order but fine-grained material like muds tend to form loosely bound aggregates (flocs) whose settling velocity can vary widely. Properties of flocculated sediment such as settling velocity and particle density are difficult to predict because they change in response to several factors including salinity, suspended sediment concentration, turbulent mixing, and organic content. Knowledge of the mechanisms governing flocculation of cohesive sediment is rapidly expanding; especially in response to recent technical advances. As the understanding of particle dynamics progresses, numerical models describing flocculation and break-up are being developed with …

2015 Chesapeake Bay Sav Coverage, Sav Data Administrator, Virginia Institute Of Marine Science

Data

Abstract: The 2015 Chesapeake Bay SAV Coverage was mapped from 1:24,000 black and white aerial photography and digital multispectral imagery with a 25cm GSD to assess water quality in the Bay. Each area of SAV was interpreted from the rectified photography and classified into one of four density classes by the percentage of cover. The SAV beds were entered into an SDE GIS fetaure class using the quality control procedures documented below. The dataset contains all SAV areas that were identified from the areas flown. Some areas that are presumed to contain no SAV were not flown. Some small beds, …

Fractal Floc Size, Density, Settling Velocity, And Implications For Water Clarity In Partially Mixed-Estuaries: The Role Of Small, Organic-Rich Particles, Kelsey Fall, Carl Friedrichs, Grace M. Massey, Jessie Turner

Presentations

Typical near-surface estuarine particles are not single solid particles, but clusters of inorganic and organic particles and water, called flocs. Floc properties that influence water clarity (such as size, composition, density and settling velocity) are challenging to observe in-situ, so their influence on the optical properties of the system is not well understood. The preliminary results presented here are part of a larger effort utilizing a combination of particle imaging equipment, water sampling, and optical instrumentation to measure important floc properties, to investigate the influence of organic particles and local hydrodynamics on those properties, and to evaluate the influence of …

Automated Calibration Of Atmospheric Oxidized Mercury Measurements, Seth Lyman, Colleen Jones, Trevor O'Neil, Tanner Allen, Matthieu Miller, Mae Sexauer Gustin, Ashley M. Pierce, Winston Luke, Xinrong Ren, Paul Kelley

USU Uintah Basin Faculty Publications

The atmosphere is an important reservoir for mercury pollution, and understanding of oxidation processes is essential to elucidating the fate of atmospheric mercury. Several recent studies have shown that a low bias exists in a widely applied method for atmospheric oxidized mercury measurements. We developed an automated, permeation tube-based calibrator for elemental and oxidized mercury, and we integrated this calibrator with atmospheric mercury instrumentation (Tekran 2537/1130/1135 speciation systems) in Reno, Nevada and at Mauna Loa Observatory, Hawaii, U.S.A. While the calibrator has limitations, it was able to routinely inject stable amounts of HgCl2 and HgBr2 into atmospheric mercury measurement systems …

Fractal Floc Size, Settling Velocity And Implications For Water Clarity In Partially Mixed-Estuaries: The Role Of Small, Organic-Rich Particles, Kelsey Fall, Carl Friedrichs, Grace M. Cartwright, D.G. Bowers

Presentations

Observations and analysis presented here suggest that properties of suspended particulate matter (SPM) in the water column of partially mixed estuaries, including floc size and settling velocity, are strongly related to the relative concentrations of inorganic versus organic matter in suspension. In regions with high inorganic SPM concentrations, addition of organic matter tends to increase the median size and settling velocity of flocs, removing both organic and inorganic SPM from the water column and enhancing water clarity relative to that in the absence of organics. In contrast, in regions with lower inorganic SPM concentration, suspended organic matter appears to decrease …

A Study Of Defensive Mechanisms Employed By Two Species Of Nudibranchs Using Toxicity And Unpalatability Analyses, Sean Youn

Independent Study Project (ISP) Collection

Nudibranchs are marine invertebrates that have developed an intriguing defense mechanism, including warning coloration and the use of chemicals accumulated through their sponge diet. The goal of this study was to determine whether the strength of chemical defenses differs between dietary and accumulated secondary metabolites for two species: Glossodoris vespa and Ceratosoma brevicaudatum. First, NMR spectroscopy was used to not only identify specific compounds in the mantle (outer covering) and the viscera (gut) but also to analyze the possibility of nudibranch species transporting more toxic compounds for defensive purposes. Next, toxicity (brine shrimp) and palatability (Palaemon shrimp) assays were used …

Self-Burial Of Objects On Sandy Beds By Wave- And Current-Induced Scour, Carl Friedrichs, S.E. Rennie, A. Brandt

Presentations

When an object sitting on the bed extends above the surrounding bed roughness, the object will alter the local flow pattern relative to the far field boundary layer. Such perturbations increase the velocities and stresses impinging on sediment immediately adjacent to the object. Nearby grains tend to be dispersed, resulting in a scour pit that deepens until the tendency for sediment to be dispersed is balanced by a tendency for sediment to fall back into the pit. The difference in pressure at the bed upstream and downstream of the object may also drive seepage flow which can cause piping and …
