Our goal is to characterize, quantify, and model material fluxes through the ocean and delivery
to the sediments (focus on organic carbon and nitrogen, silica, and inorganic carbon) as a function
of biophysical and chemical forcing functions on seasonal to decadal time scales.
Applications:
- Global carbon, nitrogen and silica budgets
- Controls on ocean remineralization & burial
- Paleoceanography & climate change
Primary Seagoing and Lab Equipment:
- Time-series sediment traps
- Sediment coring systems
- In-situ particle & plankton imaging systems
- Hydrographic and particle optical sensors
- Mini-acoustic Doppler current meters
- Coulometric carbon analyzer
- ICP atomic emission spectrometer
Recent Activities:
- Gulf of Maine Carbon Budget
- Diatom Export & Biostratigraphy - Gulf of Maine
- Benthic Nepheloid Layer/Resuspension Dynamics
- Climate Change Signals on NW Atlantic Shelf and Slope
- In-Situ Particle & Plankton Image Acquisition and Analysis
- Ocean Acidification Impacts on Productive Shelves
