Sea Water Ocean Topography (SWOT) is a radar interferometry mission making SSH measurements over a swath 120 km wide. There is a nadir gap of 20 km where the error from interferometry is not meeting science requirement. The mission's calval requirement is to validate the along-track SSH performance in terms of a wavenumber spectrum of the measurement error by comparison to in-situ measurement. The current candidate for the in-situ measurement is an array of gliders along the center of a swath to resolve the dynamic height at wavelengths of 15-150 km.

This project integrated an Acoustic Zooplankton and Fish Profiler (AZFP) multi-frequency echo sounder into a Slocum Webb G2 glider. The AZFP is complemented with existing glider sensors including a CTD, a WET Labs BB2FL ECO puck configured for simultaneous chlorophyll fluorescence (phytoplankton biomass) and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen.

Glider deployment to map the physics, optics and acoustics in the region adjacent to Palmer Station. The goal is measure the mixing, phytoplankton, and krill in a region of high foraging activity for penguins and whales. The Long Term Ecological Research (LTER) program in Antarctica is a long term study focused on understanding how the marine system regulates the ecology of the West Antarctic Peninsula. The project is focused on how the ecology is changing given the West Antarctic Peninsula is the fastest winter warming place on Earth.

The short surface ocean residence times of 1-2 days over Palmer Deep is in conflict with the prevailing hypotheses that local growth support phytoplankton at the base of the food web in these biological hotspots. Instead, the implication is that horizontal dynamics are likely more important to maintaining these biological hotspots than local upwelling. However, coincident measures of phytoplankton, prey fields, and predator locations in their advective context have not been made to establish the ecological importance of horizontal flow.

Deployment of a Slocum glider to perform seasonal surveys of dissolved oxygen concentrations in the shallow coastal waters of New Jersey. This deployment is part of the New Jersey Department of Environmental Protection's yearly coastal waters oxygen monitoring efforts. This glider carried a CTD, Seabird Scientific ECO triplet fluorescence-backscatter-chlorophyll a sensor, Sequoia Scientific LISST 200x, SeaView wave sensor, Vemco Mobile Transceiver and Aanderaa dissolved oxygen sensor.
