Risk e-Learning Webinar Series: Session II - Geospatial Platforms for Analysis and Visualization Across Environmental Data

Sponsored by: NIEHS Superfund Research Program

Go to Archive

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on SRP-funded data science projects that are enhancing the integration, interoperability, and reuse of data. With these supplements, the SRP encourages data sharing among its grantees to accelerate scientific discoveries, stimulate new collaborations, and increase scientific transparency and rigor.

In the second session, SRP-funded researchers will describe efforts to combine and analyze datasets using geospatial platforms. These platforms are being used to visualize patterns of exposures and those factors that may affect these patterns, within a geographical area. This session will also feature a speaker supported by the National Science Foundation, who will discuss HydroShare, an online system for sharing hydrologic data and models.

Pianpian Wu, Ph.D., postdoctoral researcher at Dartmouth College and Caredwen Foley, M.P.H., research assistant at the Boston University SRP Center, will discuss an examination of fish consumption advisories. To date, fish consumption advisories have been established for single contaminants, including mercury, chlordane, dichlorodiphenyltrichloroethane (DDT), dioxins, and PCBs. Surprisingly, the co-occurrence of multiple contaminants in fish tissue from these water bodies has not been systematically examined. Their work addresses the spatial differences in multi-chemical co-exposures from consuming fish, as well as highlights a need to revisit the approach to establishing fish consumption advisories that reflect exposure to chemical mixtures to address the totality of risks and benefits of fish consumption.

Andrew Creamer, research data management librarian at Brown, will describe opportunities for partnering with libraries for supporting public access to research data and data reuse. Andrew will focus on lessons learned from collecting and curating historical industrial land use data and its potential applications in data analysis and visualization and the challenges of curating publicly available datasets for reuse learned from Developing a Spatial Approach for Toxic Transferal from Industrial and Vacant Land Uses to Green Infrastructure.

David Tarboton, Sc.d., Professor, Director of the Utah Water Research Laboratory, and Professor of Civil and Environmental Engineering at Utah State University will introduce HydroShare, a repository developed for sharing data and models within the hydrology and water resources community served by CUAHSI. The presentation will describe HydroShare functionality for capturing and holding metadata as well as tools for acting on data in HydroShare that make data sharing attractive beyond open data mandates and enable problem solving through data integration. He will discuss lessons learned and challenges we still face in the management and reuse of water related data for integrated problem solving.

Pianpian Wu, Ph.D., is a postdoctoral researcher at Dartmouth College. Her research focuses primarily on mercury bioavailability at the base of the food chain in aquatic ecosystems: how mercury and its organic form, methyl-mercury, get into the aquatic food chain from water to primary producers and consumers (plankton and macroinvertebrates) for further bioaccumulation. Observation of simultaneous fatty acids composition from an ecotoxicological perspective is also addressed in her work.

Caredwen Foley, M.P.H., is a research assistant for the Boston University Superfund Research Project Research Translation Core. Her primary interest is regulatory toxicology, particularly exposure and risk assessment for organohalogens and heavy metals in occupational and residential/consumer settings. She works at the Massachusetts Office of Technical Assistance, an agency that assists Massachusetts manufacturers with pollution prevention. She also sits on the Executive Team of the BU Epidemiology COVID-19 Response Corps, where she manages projects related to COVID-19 risk communication.
