Uncertain parameters in a 3D barotropic circulation model of the German Bight are estimated with a variational optimisation approach. Surface current measurements from a high frequency (HF) radar are used in combination with acoustic Doppler current

High Frequency Radar (HFR) technology refers to land based remote sensing instruments capable of measuring surface currents and ocean waves at ranges up to 200 km or more. HFR technology is widely acknowledged as a cost-efficient tool to monitor coas

Non-coherent X-band (8–12 GHz) and S-band (2–4 GHz) marine radars have been used to aid the navigation of ships and monitor the traffic in coastal areas for decades. These traditional marine radar (MR) applications treat the radar return from the

Marine radars are increasingly popular for monitoring meteorological and oceanographic parameters such as ocean surface wind, waves and currents as well as bathymetry and shorelines. Within this paper a coherent on receive marine radar is introduced,

Oil slicks and sheens reside at the air-sea interface, a region of the ocean that is notoriously difficult to measure. Little is known about the velocity field at the sea surface in general, making predictions of oil dispersal difficult. The Ship-Tet

Much of the vertical transport near the surface of the ocean, which plays a critical role in the transport of dissolved nutrients and gases, is thought to be associated with ageostrophic submesoscale phenomena. Vertical velocities are challenging not

In this paper, a novel current inversion algorithm from X-band marine radar images is proposed. The routine, for which deep water is assumed, begins with 3-D FFT of the radar image sequence, followed by the extraction of the dispersion shell from the

This paper describes algorithms used to retrieve high-resolution wind fields in tropical cyclone conditions from synthetic aperture radar (SAR) data acquired at C-band with either co-polarization or cross-polarization. Wind directions are estimated f

Seasat (Seafaring Satellite) was launched 35 years ago on June 26, 1978, with the first civilian synthetic aperture radar (SAR) dedicated to ocean science. Unfortunately, the excitement of sending images of the ocean, ice, and Earth lasted only 100 d

This presentation studies coastal marine X-band radar (MR) bathymetry and current measurements made in Monterey Bay, California, during the Coastal Land–Air–Sea Interaction (CLASI) experiment from Jul-Aug 2021. Numerous past studies have shown co
