Personal Glider Deployment Checklist

Wednesday, July 15th, 2015

Below is a list of supplies that are strongly recommended you bring on for a glider deployment. These items will ensure that you are fully prepared as an individual with your crew.  Glider Van holds 2 people.  Most deployments take place along the coast of New Jersey and travel tends to begin at IMCS in New Brunswick, NJ.  Go on www.weather.gov and select the location of the deployment for the forecast during the mission.

  • Raincoat
  • Water-proof Closed-toed shoes
  • Sunscreen
  • Motion/Sea Sickness Medication
  • Sunglass (Hat optional)
  • Water/Juice
  • Snack
  • Sweater/Sweatshirt
  • Backpack
  • Change of clothes (just in case)

RU28 Sandy Hook Deployment

Tuesday, July 14th, 2015

On July 14th, 2015 at 8:00 am, Rutgers University Glider Ops traveled to Belmar, NJ to deploy RU28 off the coast of Sandy Hook, NJ.  The crew consisted of Tina Haskins, Nicole Waite, Andrenette Morris and Liam Ramsay.  Boat Captain Rich escorted us and our cargo of RU28, Seabird CTD and other supplies out on the ocean.

The weather was a calm overcast for the majority of the trip until it began to pour rain as we entered the Belmar-Avon Inlet on the way back.  The ocean conditions were moderate as there was a rather large swell.  The crew faired well on the trip however there was a bit of sea sickness present but nothing a little water couldn't fix.

Once we arrived at the location of the deployment, we began to prepare the Seabird CTD however there were issues turning the instrument on.  We called the COOL room for help with troubleshooting and discovered that the instrument had no charge.  Our next option was to send RU28 into the ocean and gather a quick, surface CTD reading.

RU28 was out in the water and conducted a quick 1-minute CTD dive.  The CTD readings were being transmitted back to the Glider Lab.  Once we received the message to continue, our next step was to commence with the shallow mission.

With the shallow mission, the glider dove underwater for about 20 minutes to check her ballast and to test how well she was swimming.  Once the Glider Lab contacted us with information that RU28 is on the surface, we searched for her.  We found her floating at the surface, ready to begin the mission.

The crew began the mission for RU28 and she dove.  After that, we headed back for Belmar with a job well done.  We arrived at the dock no later than 11:30 am.

silbo piloting proposal

Plots that will aid in the success of Silbo's mission

Winds vs. Currents: We can compare the wind speeds collected by buoys to see how storms affected currents. These winds, and the currents created by them, have greatly affected Silbo's journey and will continue to do so until he reaches it's end.

Deriving Estimated Range by comparing speed and battery consumption.  By looking into the remaining battery power and projections of how much more time we have and comparing it to speeds, I hope to get a ball park estimate of the range we can cover with what battery conditions we have.  This will give us an idea of how far we will be able to get with the energy we have left.

Density: As we monitor SILBO’S voyage we must also monitor the variation of water densities  that it encounters. According to SILBO Deployment Dock, the graph displaying Density vs. Water Depth,  and Sea Water Density illustrates that the water density was fairly consistent ranging from 0-100 meters, however at 100 kilometers, the water at about 500 meters(density=1030 kg) rose to a depth of about 300 meters. It is important to take matters such as this into consideration when talking about the engineering and flying of SILBO as we do not want water density to destroy the glider and alter the direction of its voyage.

Currents vs. Models: SILBO shows us where it is and where how it thinks the currents are moving.  What we are also going to compare is how accurate the glider is about the currents by contrasting it to models of the actual currents.

Battery power: Monitoring SILBO's battery power is very important because the battery is behind everything we need. If the battery dies we would have major problems. So we must keep a watch on The battery life for a successful mission. We need to estimate the battery life so we know when to intercept SILBO.

Team Conditions

Tuesday, October 18th, 2011

We are the Azores/Canaries group and our team will be looking over various aspects that can affect Silbo's travel, arrival time,  location, etc. as it makes its way to the Azores and Canary Islands. By  composing figures and plotting data for shipping frequency, sea surface height, different weather conditions, and currents speed, we will make sure nothing stands in Silbo's way and for it to have a safe, successful mission.

Plotting the future!

Monday, October 17th, 2011

Since the next leg of the Challenger mission does not have any previous glider data, we will be plotting annual average ocean data relevant to planning a transoceanic glider mission. One plot will be of annual significant wave height and current strength off the east coast of Great Abaco Island, Bahamas. This will be an integral piece of data which will allow us to plan the best launch time for the glider. The next plot will be of annual significant wave height and current strength off the west coast of Gran Canaria, Spain. We need to know the ocean weather for landing as well, since every successful launch is much more pleasant with a successful landing. The last plot we will be making is that of average annual sea surface temperature along 26.5 degrees North between Great Abaco Island and Gran Canaria in order to know the ocean temperatures we will need to endure for the mission.

Antarctic Weather Group

Monday, October 17th, 2011

This semester the Antarctic Weather Group will be looking at weather anomalies including wind, sun, and cloud anomalies. We will be making different plots using the following data: daily mean wind speed, monthly mean wind speed, yearly mean wind speed, monthly mean irradiance and cloud coverage. The data plots will help us to predict future weather patterns in the region, which will aid in other research operations around Palmer Station.

Interannual Variation of Fall Storms Proposal

Monday, October 17th, 2011

 

The Mid-Atlantic Bight group will be looking at inter annual variation of fall storms.

Specifically, we will be looking at two nor'easters, two hurricanes, and two major storms.

The major storms that we will be looking at are tropical storm Nicole on Sept. 30th 2010 and major storm on Aug. 13-15 2011. The two nor'easters are from Nov. 11-16th 2009 and April 15-16th 2007. Lastly, the two hurricanes we will be looking at will be hurricane Irene in August 2011 (provided by our other Mid-Atlantic Bight group) and Hurricane Earl from September 2010.

For all of these storms we will be looking at salinity and temperature.  As we research more information and have more data we will also be able to look at chlorophyll and the oxygen levels in the water at the time of the storms.

Gliders We will use: RU23, RU22, RU16, RU15, RU7...

Antarctic Chlorophyll

Monday, October 17th, 2011

We are the Antarctic Chlorophyll group and we are going to be looking at chlorophyll concentrations from the past 20 years. We are going to focus on concentrations around Palmer Station and the Western Antarctic Peninsula. We are also going to be looking at various nutrient concentrations to try and determine an approximate cause for any large blooms of phytoplankton. Throughout the rest of the semester we plan on making charts to show some key information. We plan on showing average chlorophyll concentrations for the months of January and February and March. We also plan to show concentrations of dissolved inorganic nutrients such as nitrate, phosphate and silicate.

As you can see in this picture the waters around Antarctica are full off life. Here the water looks green because of all of the organisms living in it!

We hope to use these graphs to  better under stand phytoplankton blooms and what is causing them to occur.

Gliding around the Ice

Monday, October 17th, 2011

So this week our assignment was to develop a plan for the plots we are going to be producing this semester. We are in charge of looking at glider operations for Palmer Station from 2001-2011. Our focus is to look for a change in the thermocline.

Our goal for the semester is to be able to plot 1) 3D temperature transects in the canyon 2) temperature for 2010-2011 3) temperature for January and February from 2001-2011 4) Salinity for January and February 2001-2011 5) Density for January and February 2001-2011. We also may look at salinity and density for the 2010-2011 field season. We are hoping to look at the changing dynamics of these three variables over time both on a short time scale (one field season) and a longer time scale (2001-2011).
