Titanium is commonly used in the aerospace industry because it is lightweight and durable in extreme temperatures. The Green Cove Springs Mine, near Green Cove Springs, Florida, was used for mining and processing titanium and other minerals from 1972 until 2009. Since then, the mine area is being reclaimed, or rehabilitated and restored to its natural state, as required by Florida Department of Environmental Protection regulations. In this study, we use high-resolution multispectral satellite and aerial imagery obtained from 2016 to 2022 to examine land cover (LC) changes at the Green Cove Springs Mine during this reclamation period. We use …

Developing A Nearshore Geospatial Framework For Recovery Assessment And Planning, Jennifer Burke, Stacy Vynne
Salish Sea Ecosystem Conference
As part of the Beach Strategies project developed by the Estuary and Salmon Restoration Program (ESRP), Puget Sound Partnership, ESRP, and Coastal Geologic Services (CGS) developed a geospatial framework to integrate nearshore data for analyses. The Beach Strategies project developed a geodatabase to inform restoration and protection planning. The Nearshore Geospatial Framework was designed as a companion structure to the Beach Strategies data to facilitate consistent and scalable units of analysis across the region-wide dataset. The framework is a series of consistent polygons with variable characteristics in both aquatic and inland areas of the nearshore. The polygon structures include variable …

Assessing the risks posed by chemical mixtures is a complex process. Ideally, details are available on exposure (e.g. which chemicals and what concentrations) and effects (e.g. mechanisms of action and toxicity data). This can be challenging even for a single location and time such as a lab or field site. Ecological risk assessments often need to cover much larger scales such as an entire watershed or a wide-ranging species. This increase in scale substantially increases the complexity. Thousands of chemicals in use lead to potential environmental mixture exposures, including pesticide runoff and municipal wastewater discharges. At the landscape scale the …
