Maryann Welsch, Senior Consultant

The Benthic Zone newsletter is the place where Integral scientists and engineers share their expertise, running the gamut of topics related to investigation, forensic evaluation, modeling, and remediation of contaminated sediment. Take a look under the water with us. 

The latest edition of The Benthic Zone features two articles from Integral technical staff.

Tim Fleming provides a technical overview of vibracoring methodology for collecting continuous sediment cores while preserving in situ stratigraphy. Through detailed examination of the Vibracore Recovery Monitoring System, he demonstrates how dual-sonar monitoring addresses common sampling challenges like rodding and pumping to improve depth attribution accuracy. Learn about the critical field deployment considerations and how this technology enhances data defensibility for contaminated sediment investigations and remedial design.

In this second installment of their eDNA series (see part 1), Integral’s Jennifer Wollenberg, Sadie McGarvey, and Maryann Welsch explore practical applications of eDNA technology across contaminated sites and broader environmental monitoring contexts. Through a case study at a former New Jersey landfill, they demonstrate how eDNA surveys provide biodiversity assessments in challenging terrain while supporting baseline documentation and post-remedy monitoring. Discover how this approach is revolutionizing threatened species monitoring, conservation efforts, renewable energy assessments, and water management from local to state levels.
