  • Aging HF Radar Network

    Posted on December 17th, 2018 Hugh Roarty No comments

    The MARACOOS HF Radar Network was formed in 2007 with the funding of the proposal “Phased Deployment and Operation of the Mid Atlantic Regional Coastal Ocean Observing System (MARCOOS)”.  The network has grown from 24 stations in 2007 up to 38 stations in 2018.  The network has been delivering hourly surface currents to the US Coast Guard since May 2009 with no interruption.  However the age of the network is weighing on the operations as some of the stations in the network are approaching 20 years of service.  The figure below chronicles the age of the radars in the network as of 2018.

    Age of HFR Stations within MARACOOD Time line indicating the age of the HF Radar stations in the Mid Atlantic.  The green line indicates stations that are less than 10 years old while red shows number of stations with a service life greater than 10 years.

    Posted on November 16th, 2018 Hugh Roarty No comments

    A storm moved through the Mid Atlantic on November 15, 2018.  The MARACOOS High Frequency radar network captured  the center of the low pressure system as it moved north past Delaware and New Jersey.


    The surface winds from the Global Forecast System (GFS) had the center of the low further inshore.


    We’ll continue to analyze these two data sets to understand the discrepancy.

  • RU29 – 2 years ago

    Posted on November 8th, 2018 Scott Glenn No comments

    Chari just sent this photo from the Perth glider port looking back 2 years at the re-christening of RU29 with water from the Indian Ocean before the start of its historic mission within IIOE-2.

    Looking back at all that was accomplished, I first think of all the people that made it possible. Working together, we advanced the technology, we explored an ocean with new threats, and we overcame new challenges on shore. We made new friends, and together, accomplished something that was hard. Some call these types of friends comrades, some call them mates.  In Spanish, we call them companeros. Our co-workers, our partners, our equals. All dedicated to a common goal. Companeros have a bond that has been tested, and a bond that has survived, because of a shared vision that is bigger than our differences.

    With the return of RU29, we now focus our attention on the next mission. I look forward to working with all of you as we prepare to redeploy from Spain in September of 2019.   The preparations will be hard, and seeing the mission through to the end will be even harder.

    But we are companeros.

    Borrowing words from our global navigator – Force, wind and honor all.

  • RU29 Damage – First look

    Posted on November 2nd, 2018 Scott Glenn No comments

    First approach.  Usual barnacles. Rudder is still attached but is hard over.


    On board the Crystal. Deep scratches on the tail, port side.


    Deeper scratches on the starboard side.


    Forward energy bay has numerous scratches.


    Pitch battery hull scratched on the bottom.



  • Hello from Marissa

    Posted on November 1st, 2018 Scott Glenn No comments

    Oscar and I are here in Marissa, same place we picked up RU29 after its record breaking mission flying from Perth, Australia.



    RU29 is currently 8 nautical miles due south of Marissa Harbor.  It is still in deep water to help with station keeping.  The surface currents are strong, so we like to wait at depth.


    Our boat is the catamaran Crystal. We stopped by today to see the vessel and meet the captain and crew.  We have two staircases down to the water level platform, one on each side.  The captain and lookouts will be on the upper deck as we approach the glider.


    Tomorrow’s schedule in Sri Lanka times:

    Van pick up at hotel 4:30 am.  At boat by 5 am.  Boat loaded and set up for 5:30 am – 6:00 am departure. On site by about 7 am our time.  We’ll get the current location of RU29, and a waypoint to head to that is just to the east of the current location.  We head to our waypoint and then turn west, approaching the glider with the sun at our back.  We will be standing on the upper deck looking for the glider with the Iridium phone getting text updates of location and the gps to let us know which way to go.

    Glider team has arrived in Mirissa Sri Lanka!  Glider is approximately 17 km off shore in 1000m water. There is a scheduled boat trip to recover glider Friday at 6am (Sri Lanka time) at Welligama Bay.

    Attached are glider packing test fits for RU29 when it is home bound.

  • 70 kilometers to pick up point

    Posted on October 20th, 2018 Scott Glenn No comments

    We did some tests flight tests on Friday, and are now back to heading towards the pick up point.  The latest measured heading plot shows RU29 is now flying about 60 degrees to the right of the commanded heading.

    Below image is zoomed into the local area with the new Copernicus model currents.  The direction we want to head is to the NE, at a heading of about 30 degrees.  With the 60 degree offset noted above, we can give RU29 a waypoint that is to the NW at a heading of 330 degrees. That new waypoint is shown in the cyan color.

    The Copernicus currents show that there is a strong current to the west just south of Sri Lanka in the region with the high vessel traffic.  That means there are two hazards if we move into that area, vessels that can hit us and currents that can sweep us away.

    Below is the important model comparison.  You always hope the models agree so that you have more confidence in the currents.

    First is Copernicus, the European model.  There is a strong alongshore current to the west offshore suthern Sri Lanka that covers the shipping lanes in red.  RU29 is in a relatively low current zone, near the middle to western side of a counterclockwise eddy.  Currents at RU29 are weak ant to the south.

    Now for the two US models.  First the Navy HYCOM.  Here RU29 is on the eastern side of a very strong and elongated clockwise eddy. The elongation is in the direction of altimeter tracks – wish I could overlay them somehow.  The strong eddy is disrupting the alongshore flow by southwestern Sri Lanka and turning it to the east.  Currents at RU29 are strong and to the southeast.

    Last is NOAA RTOFs.  Same story as Hycom, bit now the eddy is round, not elongated like an altimeter track.


  • Position prior to flight tests

    Posted on October 19th, 2018 Scott Glenn No comments


    Measured heading rose has RU29 flying about 115 degrees to the right of the commanded heading

    We made the waypoint change to give a commanded heading near 300 degrees.  This turned the glider to fly more like an ENE direction, directly at our proposed pick up point.  We are 70 km away from that point that is 40 nautical miles south of Galle, Sri Lanka and is right on the souther edge of the shipping lanes.  We have been making about 15 km of progress per day.


    We will be doing some flight tests for the remainder of this day (friday) in preparation for the station keeping we will need to do at the pick up point.
