3-D Mapping of Ocean Water Masses and Provinces

This study, led by Matthew Oliver, Matthew Grossi, and Erick Geiger from the University of Delaware, aims to map the distribution of ocean water masses and provinces using Argo profile data. The researchers will analyze the data to identify dynamic ocean biogeographic provinces. The presentation will take place on Thursday at 12:15pm and will be given by Andrew Irwin from Mt. Allison University, along with Matthew Oliver, Oscar Schofield, and Paul Falkowski from Rutgers University. The study also reflects on the European Pine Sawfly and prey density. The researchers plan to work on improving the parameterization of the curve and expanding the analysis to include temperature and salinity variations.
