This award was established to honor Dr. Donald W. Pritchard, whose insightful research on the physical dynamics of coastal systems set the stage for much of the research in physical oceanography that is being conducted today. The Pritchard Award recognizes the author(s) of the best physical oceanography paper published in Estuaries and Coasts within the two-year interval between CERF conferences.

Paper: "Impact of channel deepening on tidal and gravitational circulation in a highly engineered estuarine basin"
Chant et al. assessed the influence of channel deepening on the estuarine exchange flow, stratification, and tidal amplitude. Estuaries worldwide have been deepened for navigation, with limited understanding of effects on water quality. Channel depth affects both barotropic and baroclinic dynamics, and ultimately water quality. They show how the estuarine response to channel deepening may not always be intuitive, and how analytical scaling and observational data can be used to test hypotheses in real systems.
The scaling of Hansen and Rattray (1965) indicates that estuarine circulation should increase with the depth cubed. However, Chant et al. note that increasing depth also increases salinity intrusion length,
thereby decreasing the along-estuary salinity gradient. In the scaling proposed by Chant et al., the decrease in salinity gradient offsets the depth increase, suggesting instead that estuarine circulation is independent of depth. Similarly, they show that the change in salinity intrusion predicts that stratification should decrease with depth rather than increasing. Using observational data, Chant et al. further show that estuary geometry can prevent landward salinity intrusion and thereby contradict their revised scaling. Their scaling offers a template to evaluate physical changes in other estuaries where the salinity gradient is less constrained by estuary geometry.

Assistant Professor Grace Saba is looking forward to working with her collaborators on this new and exciting project observing ocean acidification on the U.S. Northeast Shelf from the Mid-Atlantic to the Gulf of Maine.
The Marine Technology Society promotes awareness, understanding, and the advancement and application of marine technology. Incorporated in 1963, the international society brings together businesses, institutions, professionals, academics, and students who are ocean engineers, technologists, policy makers, and educators. It is a leading authority and advocate for marine technology and resources while promoting public understanding of the ocean. Each year it recognizes outstanding individuals through their annual awards. Rutgers was well-represented in this year’s awards.
Congratulations to Josh Kohut (Professor), who was named a Fellow of the Marine Technology Society. He was recognized for fundamental contributions in the development of novel technologies that are allowing us to sample marine systems. Josh has been at the forefront of the deployment and operation of a range of technologies that are helping science, health & human safety at sea, as well supporting sustainable fishery management.
Congratulations to Sarah Murphy (graduate student) who is a 2019 recipient of an MTS Student Scholarship for Graduate Students. Her research is focused on the interaction of coastal ocean and atmospheric processes and their influence on offshore wind power production. She is utilizing the new geostationary satellite GOES-R and the weather research and forecasting (WRF) model, to understand the impact of rapidly evolving SST fields on wind speeds at wind turbine hub height.
Congratulations to Jessica Valenti (graduate student) who is a 2019 recipient of a MTS Student Scholarship for Graduate Students. Her research involves assessing impacts of urbanization (anthropogenic land development) on estuarine fishes and relies heavily on marine technology for success. The technologies she uses to complete the fieldwork portion (fish collection) of her research span the gamut from the boat motor and GPS that make it possible to navigate shallow, estuarine waters to be sampled with the Yellow Springs Instrument (YSI).
Congratulations to Julia Engdahl (Operational Oceanography Masters student) who was awarded the Paros-Digiquartz Scholarship towards her studies.
