HFR surface currents observing system in lower Chesapeake Bay and Virginia coast

Surface currents are measured using high frequency (25 MHz and 5 MHz) radar in the lower Chesapeake Bay and offshore in the Mid-Atlantic. The data have become quite reliable and of high quality over the past couple of years. This paper describes the existing system, the dataset, the quality of data and some examples of how it is being used. It also presents results of recent analysis of mean currents within the lower Bay.
