Mixing and phytoplankton dynamics in a submarine canyon in the West Antarctic Peninsula

Journal of Geophysical Research: Oceans, Volume 121, Issue 7, Page 5069-5083, July 2016., 2016
Abstract Bathymetric depressions (canyons) exist along the West Antarctic Peninsula shelf and have been linked with increased phytoplankton biomass and sustained penguin colonies. However, the physical mechanisms driving this enhanced biomass are not well understood. Using a Slocum glider data set with over 25,000 water column profiles, we evaluate the

Attractive Lagrangian Features in the Mid‐Atlantic Bight: Using Lagrangian Coherent Structures to Describe Seasonal and Interannual Changes in Circulation

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Coastal ocean dynamics are complex with influences from freshwater input, alongshore flows, offshore slope water intrusions, and overlapping mixing and stratification processes. This complexity makes it difficult to elucidate patterns in observed coastal circulation important to our understanding of natural and anthropogenic marine ecosystem ...

CODAR intercomparison: Delaware Bay 1984

Proceedings of the 1986 IEEE Third Working Conference on Current Measurement, 2005
During the fall of 1984 surface current measurements were made by means of a Coastal Ocean Dynamics Application Radar (CODAR) in the Delaware Bay during the National Ocean Service's (NOS) Delaware River and Bay Project. This project included a survey of the circulation of the estuary, operation of a real-time numerical circulation model, and real-time ...

Gap Filling of the CALYPSO HF Radar Sea Surface Current Data through Past Measurements and Satellite Wind Observations

International Journal of Navigation and Observation, Volume 2016, Issue 1, 2016., 2016
High frequency (HF) radar installations are becoming essential components of operational real‐time marine monitoring systems. The underlying technology is being further enhanced to fully exploit the potential of mapping sea surface currents and wave fields over wide areas with high spatial and temporal resolution, even in adverse meteo‐marine ...

East Australian Current System: Frontal Barrier and Fine‐Scale Control of Chlorophyll‐a Distribution

Journal of Geophysical Research: Oceans, Volume 129, Issue 3, March 2024.
Abstract The East Australian Current (EAC), as the western boundary current of the South Pacific Gyre, governs the mesoscale circulation dynamics along the East Coast of Australia. It also exhibits meandering and instabilities that generate fine‐scale structures.

Forecasting of Surface Currents via Correcting Wind Stress with Assimilation of High‐Frequency Radar Data in a Three‐Dimensional Model

Advances in Meteorology, Volume 2016, Issue 1, 2016., 2016
This paper details work in assessing the capability of a hydrodynamic model to forecast surface currents and in applying data assimilation techniques to improve model forecasts. A three‐dimensional model Environment Fluid Dynamics Code (EFDC) was forced with tidal boundary data and onshore wind data, and so forth.

Wave Observations from Central California: SeaSonde Systems and In Situ Wave Buoys

Journal of Sensors, Volume 2011, Issue 1, 2011., 2011
Wave data from five 12‐13 MHz SeaSondes radars along the central California coast were analyzed to evaluate the utility of operational wave parameters, including significant wave height, period, and direction. Data from four in situ wave buoys served to verify SeaSonde data and independently corroborate wave variability.

Analysis of Monterey Bay CODAR-derived surface currents, March to May 1992 [PDF]

, 1992
HF surface current radar (CODAR) data from two shore-based radar sites were collected and combined to form vector estimates of the near-surface currents in Monterey Bay from March to May 1992. CODAR-derived currents are measures of the flow in the upper
