  • TS Arthur tracks along the Gulf Stream

    Posted on May 19th, 2020 Scott Glenn No comments

    Below is the view of Tropical Storm Arthur in the MARACOOS OceansMap.

    The track of Arthur follows the warm water of the Gulf Stream observed in the satellite SST. Arthur is forecast to now turn more towards the south.  Arthur tracked close to 2 gliders that were flying in the Gulf Stream, Silbo operated by TWR and a spray glider operated by WHOI.  Silbo in black is shown leaving the Gulf Stream to the north while the Spray glider in gray continues west with the Stream.  Currents from the MARACOOS HF Radar network on the Mid Atlantic shelf are strong and alongshore towards the south.



    A quick look at the global model temperature profiles as Glider Silbo leaves the Gulf Stream looks like a much faster departure in the models than in the real world.  We’ll look more at the slope sea comparison when the glider is out of the Stream in both the model and real world conditions.  Plots from all the gliders can be viewed at

    NHC warnings included heavy surf along the Mid Atlantic coast from Arthur.  Some of the HF Radar systems in the Mid Atlantic are set up to monitor waves in real time and send the data to the NWS forecast offices.  Above is one example of HF Radar derived waves along the NJ coast at Seaside Park, the first site to break 3 m.  Waves from the NDBC sites further offshore are approaching 9 ft.  The full HF Radar waves dataset can be accessed at



  • TS Arthur forecast to turn just south of the gliders

    Posted on May 18th, 2020 Scott Glenn No comments

    Tropical Storm Arthur is forecast to move parallel to the North Carolina coast today.  The morning forecast discussion from the National Hurricane Center indicates that “Arthur is moving near and almost parallel to the Gulf Stream”.  Several gliders are deployed in the slope sea or Gulf Stream just north of the forecast track, with glider Silbo being in the most southern position.



    In the above figure temperature profiles from the global models are compared to glider Silbo.  Profiles from the U.S. data assimilative GOFS and the operational RTOFS have similar features and agree well above 400 m and below 800 m.  The transition between the 18C water near 300 m depth and the 7C water near 800 m depth is often related to differences in the position of the Gulf Stream.  The global model from Copernicus starts near the same surface temperature, likely due to similar satellite Sea Surface Temperatures being assimilated, and is similar in the deep water at 1000 m, but what happens in between is has a very different shape.


  • New 2020 Ocean Forecast Workflow for Hurricanes

    Posted on May 15th, 2020 Scott Glenn No comments


    There are 3 steps in the workflow for the ocean component of NOAA’s operational hurricane forecast models HMON and HWRF.

    Step 1 is data assimilation.  This is accomplished by the Navy using the Global Ocean Forecast System (GOFS) version 3.1.  The data is assimilated using the Navy Couple Ocean Data Assimilation (NCODA) system. Data from each day is typically inserted over a 3 hour insertion window running from 9Z to 12Z each day.  Major datasets for assimilation include satellite Sea Surface Temperature (SST), satellite sea surface height from altimeters, data from profiling instruments like Argo and underwater gliders, etc.

    Step 2 is to layer on the NOAA global windfield from GFS.  Here the NOAA global Real Time Ocean Forecast System (RTOFS), starting at day 0, looks back 2 days and extracts from GOFS 3.1 its initial condition (IC). That initial condition is then run forward back up to day 0 without data assimilation with forcing from the EMC GDAS. Then on day 0, the wind forcing is switch to GFS to run RTOFS for several days into the future.  Starting in August 2020, it is anticipated that and experimental version of RTOFS Data Assimilation (RTOFS-DA) will be run.  Thus there are 3 US global ocean models to compare to observations this coming hurricane season – operational GOFS3.1 with NCODA, operational ROTFS without data assimilation, and experimental RTOFS with RTOFS-DA.  We hope to expand this to include the European global ocean forecast system available through Copernicus.

    Step 3 is to extract initial conditions (IC) and Boundary Conditions (BC) from RTOFS every 6 hours to initialize the regional ocean models that are coupled to the atmospheric forecast models HMON and HWRF. The operational HMON atmospheric model is coupled to a regional HYCOM ocean model. The HWRF atmospheric model is coupled to both  HYCOM and POM ocean models.  It is anticipated that for the 2020 hurricane season, the operational HWRF will be coupled to POM, and an experimental HWRF will be coupled to HYCOM. This makes at least 3 different oceans that will be present under hurricanes this season.  The commonality in 2020 is that all 3 oceans will start from the same initial condition provided by ROTFS every 6 hours. The difference will be what ocean model and what windfield is used to evolve the initial conditions, and how much difference that makes during the storm forecast.


  • RUCOOL Updates: February to March, 2020

    Posted on May 15th, 2020 Mike Crowley No comments

    Despite the COVID-19, RUCOOL remains active and excelling.  Core technologies (storm gliders and HF Radar) were deemed critical research tools based on national security requirements and continue to be supported. These activities are guided by an operations plan that maintains recommended self-distancing practices. In fact, RUCOOL has developed standard operating procedures for glider deployments leveraging social distancing requirements, which have been shared with multiple funding agencies and research partners. The operating guidelines are available upon request.


    • In early April, the first operational oceanography Masters students will be submitting abstracts of their thesis to the Marine Technology Society OCEANS meeting. One of the Masters students has already accepted a job working for NOAA’s operational oceanography service following her degree.
    • RUCOOL initiated two projects with Atlantic Shores Offshore Wind, the joint NJ offshore wind project between EDF Renewables and Shell New Energies. One project is installing a vertically pointing wind lidar at the Rutgers Marine Field Station. The second is a modeling study of visibility conditions along the NJ coast.
    • RUCOOL hosted Commissioner Dianne Solomon of the New Jersey Board of Public Utilities for a tour and discussion of offshore wind.
    • In March, 4-H launched a Virtual 4-H at Home Short Term Exploratory Program (STEP).  The program was entitled: Exploring Life in the Southern Ocean and consisted of three 1.5 hour classes geared towards 5th-8th grade students – see Young people from across the state participated in this inaugural program led by the RUCOOL education team.
    • To fill the gap of in person 4-H STEM learning due to COVID-19, the RUCOOL education team has joined a larger Rutgers group that has created a new 4-H STEM Blog to help kids connect to STEM activities from home:


    • Grace Saba presented an invited to Sea-Bird Scientific on the glider pH efforts and path forward for an industry-academic partnership. Grace runs the only two pH gliders in the world.
    • The RUCOOL Education and Science teams lead the authoring of a special issue for the National Marine Educators Association Journal called Current –
    • Hugh Roarty travelled to Vessel Traffic Service (VTS) Centers around the United States (Port of New York, Houston, Louisville and Port Arthur) to evaluate the Coast Guard use of HF radar to manage traffic in the ports. Existing microwave radars operated by the United States Coast Guard (USCG) do not provide reliable detection of small vessels.  Hugh will meet with Coast Guard personnel at the twelve MORE VTS centers and develop a needs analysis with respect to radar remote sensing.
    • For the NASEM HF-Radar work in the Gulf of Mexico, RUCOOL is improving CODAR ship detection software. Tests are being performed by comparing data acquired near two oil platforms in the Gulf of Mexico and from the Sandy Hook NJ site, to the national Automated Identification System (AIS) ship tracking data.


    • RU COOL scientists working on the NSF-funded Palmer LTER and Project SWARM connected with thousands of K-12 students this past winter in 10 live video teleconferences (VTCs) from Palmer Station, Antarctica. The education team recruited and prepared 25 teachers from 21 schools in 11 states (NJ, DE, NY, CT, VA, FL, AL, MN, AZ, OR, CA), reaching 1060 students directly and many more via the call recordings that are shared online.  The interaction helps build science identity as reported by teachers.
    • Several members of the RUCOOL team attended the Ocean Sciences meeting in San Diego in late February, which is the world’s largest oceanography conference, delivering 20 presentations (many are available on our website). Grace Saba co-chaired the town hall on Exploration of the Twilight Zone Ocean Network (JETZON), which published a piece in Nature last week
    • The RUCOOL team collected data for the last 30 years as part of the NSF funded Palmer Long Term Ecological Research program, that is conducting a long term study of how a changing climate will impact polar marine ecosystems along the West Antarctic Peninsula (WAP). This year leadership of the Palmer LTER was transferred to Rutgers which is the principal institution running this multi-university long term effort.
    • RUCOOL lead a team partnered with the University of Delaware, Oregon State University, Old Dominion University, Polar Oceans Research Group, and University of Alaska Fairbanks to deploy a polar ocean observatory off the coast of Antarctica. COVID-19 provided a challenge with travel logistics as scientists and students were scheduled to arrive home in late March. The entire team arrived home safely in late March, thanks to a great deal of help, cooperation and communication between gov’t agencies, airlines and universities. It’s good to have them back.

  • Navy Gliders View the Cold Pool

    Posted on October 25th, 2019 Mike Crowley No comments

    Two Navy gliders were deployed in the Middle Atlantic Bight (MAB) between September 11 & 26, 2019. Their cross-shore trajectories were planned to capture the cold pool, a cold bottom layer of water that characterizes the MAB at this time of the year. There transects are shown below.

    In the figures below, the top figure shows the cross-shore temperature transect for glider ng618. In this figure the cold pool can be identified as the bottom water with temperature less than 10 degrees Celsius. The cold pool has important implications for the fisheries of the region and it can become a “fire extinguisher” for tropical cyclones by lowering the sea surface temperature through vertical mixing during the passage of a storm.

    The bottom figure shows the same ng618 glider trajectory from the Global Ocean Forecasting System (GOFS 3.1) that is a global operational ocean model run by the US Navy. The comparison between glider observations and the GOFS model are remarkably good.

  • RUCOOL Updates August-September 2019

    • Masters students have and will continue to participate in national Marine Technology conferences and career networking events this fall.


    • The RUCOOL Glider team was involved with five deployments in August and September. These deployments include work supporting NJDEP water quality research along the NJ coast, NASA research off of central California to validate a new sea surface height satellite, and NOAA and privately funded investigations of hurricane interactions with the ocean surface in the Mid-Atlantic Bight and Caribbean.
    • RUCOOL deployed two Navy gliders in partnership with the Navy, NOAA OAR, MARACOOS and Monmouth University. Within two weeks, both gliders called into the Navy pilots, indicating that there were leaks. RUCOOL scrambled vessels from NorthStar Marine to recover these gliders at 3am on Sunday, September 22, and at 2am on Sunday, September 29. Both were recovered approximately 100 nautical miles from shore, within 48 hours of the first notification of a problem. If not for the round-the-clock efforts of RUCOOL, these navy gliders would have been lost as the leaks were severe in both cases.
    • DMCS completed its work with the NSF funded REU program, RIOS. Students worked with mentors over a 10 week program that supported their research and provided weekly workshops that developed their career and research aptitude.  The program was coordinated by Josh Kohut, and additionally 3 other RUCOOL scientists directly mentored students, and two RUCOOL scientists supported the RIOS career workshop.  The summer program concluded in August with a science symposium in which the students shared their work and celebrated their research success.

  • Low Surface Salinity During Tropical Storm Karen

    Posted on October 3rd, 2019 Mike Crowley No comments

    During Tropical Storm Karen, there were 10 gliders deployed in the Caribbean (below). On Sep 24, the eye Karen passed over Navy glider NG278, just south of St. Croix.

    There is a good agreement in the vertical structure of temperature between GOFS 3.1 and the glider temperature (below).

    The GOFS 3.1 model, however, has a surface fresh layer (barrier layer) that is not as sharp as the observations show. This barrier layer gets even fresher and shallower during Karen (below). At the moment we are investigating if this freshening can be attributed to increased precipitation during the storm. If this is the case, this can be a mechanism that reinforces stratification during a storm and inhibits vertical mixing. We would like to investigate how important this possible mechanism is in controlling the storm intensity.

    The freshening that happened during Karen (Sep 23 – Sep 24) is not initially captured by any of the models (below).

    By Sep 26, the surface salinity in GOFS and Copernicus were much closer to the observations (both models assimilate data) but RTOFS still lags behind (below).

    Images of these daily comparisons, since the inception of the 2019 hurricane season, are available here.

  • There are a lot of gliders out there!

    Posted on October 1st, 2019 Mike Crowley No comments

    The 2019 hurricane season is in full swing in the Atlantic Ocean. Since the inception of the hurricane season on June 1, 42 ocean gliders have been deployed in the western Atlantic ocean by numerous academic, corporate and government partners. These gliders have acquired over 68,000 profiles of temperature and salinity to date. Some gliders also record data on water optics, oxygen, current speeds, pH, and wave heights. A distribution of the groups funding the deployments is shown below as well as a map of their locations.
