Dr. Marcus W. Beck

USEPA NHEERL Gulf Ecology Division

Marcus Beck (This email address is being protected from spambots. You need JavaScript enabled to view it.) is a post-doctorate research fellow with the USEPA Gulf Ecology Division in Gulf Breeze, FL.   He has a MSc and PhD in Conservation Biology, including a minor in Statistics from the Conservation Biology Program at the University of Minnesota. His research focuses on the analysis of large datasets to support decision-making in water quality monitoring programs.   His current work with the EPA includes analysis of time series data from the SWMP database and the development of analytical tools to support a nationwide study of estuarine metabolism. Marcus has extensive experience with the program R for statistical analysis and is a regular contributor to the R-bloggers website. His most recent R package, SWMPr, provides easy-to-use functions to retrieve, organize, and analyze SWMP data for time series analysis.

Todd has spent much of the last ten years working with plankton and hydrographic time series. He currently manages a cooperative database of over 200 oceanic, shelf, and coastal "marine ecological time series" for ICES, SCOR, and IOC/UNESCO plankton and ecosystems working groups. Through his work with these groups, Todd has hands-on experience with the challenges and methods of comparing disparate time series data from hundreds of different locations, methodologies, sampling frequencies, and variable types.

Grand Bay National Estuarine Research Reserve

Kim Cressman (This email address is being protected from spambots. You need JavaScript enabled to view it.) is the Water Quality Monitoring Coordinator for Grand Bay NERR. She has a master’s degree in marine biology from the University of North Carolina Wilmington, where she studied effects of intertidal oyster reefs on water quality. Throughout her career, Kim has been involved in all aspects of water quality monitoring, from field collection and lab analyses to data management and reporting. At Grand Bay, she oversees day-to-day SWMP data collection and QA/QC, equipment maintenance and troubleshooting, and nutrient analyses. She has experience connecting people to natural resources through volunteer programs, and actively works to synthesize, analyze, and understand monitoring data so it can be applied to real-world situations.
