National Marine Mammal Foundation

JHT provides the National Marine Mammal Foundation (NMMF) with over 20 years of combined expert-level vessel handling, safety and logistical support and dolphin research. Team members provide technical support for marine mammal field studies in Barataria Bay, Louisiana – an area heavily impacted by the Deepwater Horizon Spill in 2010 (ABC News Deepwater Horizon Oil Spill ). JHT staff offer ongoing assistance with critical fieldwork efforts that include dolphin capture release planning and logistics coordination for boats and equipment, photo-id analysis and monitoring, specimen analysis, data reporting and marine mammal handling.

Employee Spotlight

Lisa C. Wickliffe, PhD
Lisa supports marine spatial ecology for the NOAA NOS NCCOS, Coastal Aquaculture Siting and Sustainability program. Her research focuses on marine aquaculture resource mapping, including site screening and selection, exclusion analyses, suitability modeling, decision-making analysis and tool development for aquaculture. She also works on biogeographical assessments of priority fisheries species to inform aquaculture siting and environmental models. She received a BS in Marine Science at the University of South Carolina, a MS in wildlife and fisheries biology at Clemson University and a PhD in Environmental Health Sciences at University of South Carolina.

Climate Change and Watershed Hydrology—Heavier Precipitation Influence on Stormwater Runoff

Authors: Anne C. Blair and Denise Sanger

Abstract Excerpt: Stormwater runoff in the USA is a main driver of non-point source pollution and other major problems for urbanizing areas, and runoff effects will be exacerbated by the increased frequency and intensity of heavier storm events that are projected as climate changes. The purpose of this paper is to consider how increased rainfall from storms could influence direct stormwater runoff in urbanizing watersheds.
