Barriers and benefits to desired behaviors for single-use plastic items in northeast Ohio’s Lake Erie basin

OHSU-POST-1521
ABSTRACT:

Given the growing saliency of plastic marine debris, and the impact of plastics on beaches and aquatic environments in the Laurentian Great Lakes, applied research is needed to support municipal and nongovernmental campaigns to prevent debris from reaching the water’s edge. This study addresses this need by examining the barriers and benefits to positive behavior for two plastic debris items in northeast Ohio’s Lake Erie basin: plastic bags and plastic water bottles. An online survey is employed to gather data on the use and disposal of these plastic items and to solicit recommendations on how to positively change behavior to reduce improper disposal. Results support a ban on plastic bags and plastic water bottles, with more enthusiasm for a bag ban. Financial incentives are also seen as an effective way to influence behavior change, as are location-specific solutions focused on education and outreach.

Intercomparison of Approaches to to the Empirical Line Method for Vicarious Hyperspectral Reflectance Calibration

OHSU-POST-1523
ABSTRACT:

Analysis of visible remote sensing data research requires removing atmospheric effects by conversion from radiance to at-surface reflectance. This conversion can be achieved through theoretical radiative transfer models, which yield good results when well-constrained by field observations, although these measurements are often lacking. Additionally, radiative transfer models often perform poorly in marine or lacustrine settings or when complex air masses with variable aerosols are present. The empirical line method (ELM) measures reference targets of known reflectance in the scene. ELM methods require minimal environmental observations and are conceptually simple. However, calibration coefficients are unique to the image containing the reflectance reference. Here we compare the conversion of hyperspectral radiance observations obtained with the NASA Glenn Research Center Hyperspectral Imager to at-surface reflectance factor using two reflectance reference targets. The first target employs spherical convex mirrors, deployed on the water surface to reflect ambient direct solar and hemispherical sky irradiance to the sensor. We calculate the mirror gain using near concurrent at-sensor reflectance, integrated mirror radiance, and in situ water reflectance. The second target is the Lambertian-like blacktop surface at Maumee Bay State Park, Oregon, OH, where reflectance was measured concurrently by a downward looking, spectroradiometer on the ground, the aerial hyperspectral imager and an upward looking spectroradiometer on the aircraft. These methods allows us to produce an independently calibrated at-surface water reflectance spectrum, when atmospheric conditions are consistent. We compare the mirror and blacktop-corrected spectra to the in situ water reflectance, and find good agreement between methods. The blacktop method can be applied to all scenes, while the mirror calibration method, based on direct observation of the light illuminating the scene validates the results. The two methods are complementary and a powerful evaluation of the quality of atmospheric correction over extended areas. We decompose the resulting spectra using varimax-rotated, principal component analysis, yielding information about the underlying color producing agents that contribute to the observed reflectance factor scene, identifying several spectrally and spatially distinct mixtures of algae, cyanobacteria, illite, haematite, and goethite. These results have implications for future hyperspectral remote sensing missions, such as PACE, HyspIRI, and GeoCAPE.

Stormwater Best Management Practices for Marinas

OHSU-POST-1516
ABSTRACT:

In 2008, the Ohio EPA implemented the National Pollutant Discharge Elimination System (NPDES) General Permit for Industrial Activity from Marinas. The permit covers any marinas in Ohio that conduct industrial boat maintenance activities including rehabilitation, repair, painting and certain equipment cleaning operations. The Ohio Clean Marinas Program is a proactive partnership designed to encourage marinas to use simple, innovative solutions to keep Ohio’s coastal and inland waterway resources clean. The basic goal of the program is environmental stewardship by making marina operators more aware of environmental laws, rules and jurisdictions. The Best Management Practices (BMP) Guidebook discusses specific practices that marinas should voluntarily implement to control impacts to water quality and habitat from marina operation and maintenance activities. A case study of Piedmont Marina in Freeport, Ohio was developed to highlight successful stormwater BMPs and provide guidance for retrofitting existing marinas to comply with NPDES requirements or to improve water quality.

To Eat or Not to Eat? Feeding and Growth Strategies in Neonatal Lake Erie Watersnakes

OHSU-POST-1512
ABSTRACT:

Early growth has major impacts on life characteristics such as survival and reproduction in vertebrate taxa. Consequently, most New World natricine snakes begin feeding and growing immediately after birth and can reach sexual maturity by their second year. Previous studies of the demography, diet, and behavior of the Lake Erie Watersnake (Nerodia sipedon insularum) have shown that this natricine differs by growing more slowly and delaying maturity until the third or fourth year. A plot of snout-vent-length vs. day of year for the youngest age class suggests there is no growth in the period preceding the snakes’ first hibernation, and prey has never been recovered from a neonate in the field. This suggests that in contrast to other natricines, Lake Erie Watersnakes delay feeding and growth until after emergence from their first hibernation. I investigated this delayed feeding in three parts by performing feeding trials with pre- and post-hibernation neonates, continuing field prey studies, and quantifying energy reserves available to young snakes in the form of yolks and fat bodies. For the feeding trials, binary logistic regression analysis detected a significant positive relationship between age of neonate and probability of feeding. This was reinforced by a sharp increase in field prey consumption by post-hibernation neonates. Comparison of fat reserves revealed that Lake Erie Watersnakes have significantly larger combined yolks and fat bodies than other neonatal natricines, suggesting a possible mechanism for delaying growth and feeding until after the first hibernation.

Gene Diversification of an Emerging Pathogen: A Decade of Mutation in a novel Fish Viral Hemorrhagic Septicemia (VHS) substrain since its first appearance in the Laurentian Great Lakes

OHSU-POST-1511
ABSTRACT:

“Viral Hemorrhagic Septicemia virus (VHSv) is an RNA rhabdovirus that causes one of the world’s most serious fish diseases, infecting >80 species across the Northern Hemisphere. A novel and virulent substrain, IVb, first appeared in the Laurentian Great Lakes about a decade ago, resulting in massive fish kills, rapid spread, and genetic diversification. We analyzed temporal and spatial mutational patterns in the non-virion (Nv), glycoprotein (G), phosphoprotein (P), and matrix (M) genes. Our results show the Nv-gene has been evolving the fastest, with the G-gene second fastest. P- and M- genes are evolutionarily conserved and display slower rates of change. Samples from Lakes Erie and Ontario contained the greatest haplotype diversity. Since the 2006 outbreak, variants have increased in number, perhaps in response to fish populations developing resistance. Rapid evolutionary differentiation may allow new variants to evade fish host recognition and immune responses, facilitating persistence along with geographic expansion.”

Copper Concentrations at Lake Erie Marinas: Working together to understand and find solutions for nonpoint source pollution

OHSU-POST-1501

Poster presenting the preliminary results of an Ohio Sea Grant research project on copper concentrations in Lake Erie marina sediments.

ABSTRACT:

One of the recent and challenging topics in the marina industry is managing wastewater from boat bottom washing. After the ban of tributyltin in the 1980s, copper became the primary biocide used in antifouling paints. The effects of copper on aquatic organisms have been well documented in the scientific community, and copper is listed on the Agency for Toxic Substances & Disease Recovery’s Priority List of Hazardous Substances. Copper oxide leaches from the boat bottom surface, often entering the water as a free copper ion and adsorbing suspended particulate matter as it settles and accumulates in the sediment. As a result, copper concentrations in sediment are often two to three orders of magnitude greater than in the water column. Ohio Sea Grant collaborated with Bowling Green State University and Lake Erie marinas to establish preliminary data on copper accumulation in sediment over the course of one boating season, and to quantify the amount of copper contributed by boat bottom washing during that season. Sediment samples were taken at 8 marinas along Lake Erie, at three targeted locations: the boat haul-out area, permanent dockage, and at the mouth of the marina. The project aided scientists, agencies, marina owners, and boaters in obtaining a better picture of the contribution of boat bottom wash wastewater to copper concentrations in Lake Erie nearshore sediments, and in finding sustainable solutions for boat bottom washing.
