Bottom-mounted Acoustic Doppler Current Profilers (ADCPs) have been demonstrated to be a practical method of obtaining high quality observations of surface wave height and direction in shallow water (typically less than 30–40 m). This restriction has motivated several groups over the past few years to investigate the possibility of using ADCPs for wave measurements in deeper water by deploying them...
Measuring currents and waves from a subsurface mooring using ADCPs is a useful technique in regions of the world where the use of surface buoys is problematic — either because of ship traffic or theft. This paper evaluates the utility of inexpensive MEMS-based inertial sensors for measuring the platform motion. We find that these sensors are capable of providing the necessary measurements of attitude...
The University of Maine Ocean Observing System (UMOOS), a member of the Northeastern Regional Association of Coastal and Ocean Observing Systems (NERACOOS), has been operated by the University of Maine's Physical Oceanography Group (PhOG) since 2001. UMOOS currently maintains five real-time data buoys in the coastal Gulf of Maine (GoM) and two in the offshore GoM. Since September 2013, PhOG has been...
The WERA system (WavE RAdar) is a shore based remote sensing system to monitor ocean surface currents, waves and wind direction. This long range, high resolution monitoring system is based on short radio wave radar technology. The vertically polarized electromagnetic wave is coupled to the conductive ocean surface and follows the curvature of the earth. This over the horizon oceanographic radar can...
This paper summarizes the quality control (QC) tests used to verify ocean wave and in situ current data collected and shared by ocean observing systems, federal data centers and oceanographic research institutions. The categories in common for both waves and currents are defined as: (1) sensor health, (2) signal quality, and (3) parameter quality. The main differences being that while wave measurements...
Since April 2006, long range (8.3MHz) WERA HF radars have been operated on the Southeastern United States coastline, as part of the U.S. Integrated Ocean Observing System (IOOS) and in particular the national HF Radar network. These radars measure currents operationally, and waves and winds experimentally across the wide continental shelf of Georgia (GA) and South Carolina (SC). Half-hourly data at...
Hydrodynamic measurements of the very nearshore are valuable, but often difficult to obtain. Large amounts of bubbles due to wave breaking and complex installation complicate the use of acoustic instruments in this zone. This paper presents measurements obtained by a horizontal looking ADCP (hADCP) installed in the very nearshore to measure waves and wave currents. The observations are separated into...
Summary form only given. Scientists of the Naval Oceanographic Office (NAVOCEANO) provide specialized operationally-significant products and services for military "warfighters." These products are also provided for civilian, national and international customers under some circumstances and with some constraints. Our scientists acquire global ocean and littoral data from sources such as:...
