Real time systems

Hi there

The number of online wave and current profiling systems is growing quite rapidly. As an encouragement to us all - and showing that it isn't all hype - we propose that you take 5 minutes to list your system here.  In addition to showing that it actually can be made to work, we could all do with some ideas for what the WEB graphics should look like " />'>

The first one we would like to share with you is real time observing system developed by Justin Vandever and other at VIMS.  The system has been up and running for a year and the data is collected by an AWAC and processed with an internal NIP.  It is sent via underwater acoustic modem to a surface buoy and the radio link back to VIMS completes the telemetry.  Pretty cool!

Hi, here is a site with some really fancy graphics -- but not quite acessible to those of us who cannot read Chinese properly.

Cal Poly (San Luis Obispo, California) reports real-time AWAC data using the Nortek SeaState software on their website:  http://www.marine.calpoly.edu/awac/Summary.png   (summary)

Good work to Ian et al. for getting this system online!

 

Through support from the U.S. Army Corps of Engineers (USACE) and the National Oceanographic and Atmospheric Administration (NOAA), researchers from ECU (Walsh and Corbett) are working with scientists from the Coastal Studies Institute (Mike Muglia, Mike Remige and Nancy White), Elizabeth City State University (Jinchun Yuan) and the USACE (Jeff Hansen) to monitor atmospheric and estuarine conditions in Albemarle Sound.

Below is a link to a plot of wave parameters measured by a Vector velocimeter.

CNR ISMAR (Institute of Marine Sciences of the National Research Council) "acqua alta" oceanographic tower 9 miles offshore Venice (Italy) reports real-time and last 72 h AWAC and weather data using the Nortek SeaState software on our website:

The Stevens Institute in Hoboken, NJ, operates a Nortek ATON System mounted on a Coast Guard Aid-to-Navigation buoy in New York Harbor.  The ATON System uses a 1 MHz Aquadopp Profiler to monitor the current profile in the navigation channel.  These data are compared to a regional numerical model and displayed in real-time on the New York Harbor Observing and Prediction System (NYHOPS) website: http://hudson.dl.stevens-tech.edu/maritimeforecast/maincontrol.shtml

To view the real-time current profiles, select:

     Region: Vertical Current Profiles

     Parameter: Stevens on ATON 30, NY

 

The Coastal Studies Institute of North Carolina, in collaboration with the USACE FRF, has deployed a 1 MHz AWAC off of Jennette's Pier in North Carolina.  The AWAC is cabled to shore and uses both Nortek real-time processing software and Wavector software written by Jeff Hanson.

Update, October 1, 2009

Go to http://www.frf.usace.army.mil/frfzoom.shtml and click on 8m AWAC.
Click on any plot to enlarge.

The wave products that you see are all produced by XWaves and are also
available in Wavector

Soon I will have a web page devoted to the cross-shore wave array and
provide some examples from all of the AWACs.

The first coastal data observation buoy for the Caribbean Integrated Coastal Ocean Observing System was deployed near the Puerto Rico insular shelf break about 1.4 nautical miles south-southeast of Caja de Muertos Island on June 9, 2009 at 17° 51.61’N 66° 31.43’ W. The buoy communicates via acoustic modems with a bottom mounted Nortek AWAC with AST and provides realtime data on winds, waves, currents, seawater temperature and salinity.

To view real-time data from the AWAC, select "Data Download" followed by "doppler."

As of November 10, 2009, Tony Whipple from UNC has linked a cabled AWAC at Bogue Inlet Pier in North Carolina to the NCCOOS website:

According to Tony, it has been sampling away flawlessly. 

Here is the latest version of the real time AWAC system in Taiwan:

It looks best if you have Chinese characters on your computer.

The NOAA Great Lakes Environmental Research Lab (GLERL) has deployed a 600 kHz AWAC for real-time measurements in Saginaw Bay, Lake Huron.  The AWAC uses a ProLog for real-time wave processing and transmits data, via cable, to a surface buoy and then on to shore.  The comprehensive NOAA realtime website is here: http://www.glerl.noaa.gov/res/recon/station-sbb.html
