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).

SILBO: Density

SILBO: 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.

 

 

 

Proposal: Summer 2011 Bloom

Wednesday, October 12th, 2011

These are the figures that our group is creating. These figures will depict the dynamics of the phytoplankton bloom that occurred off the New Jersey coast this past summer (summer 2011). The figures will show the following:

1) Possible causes of the bloom chemicals (runoff)
2) Temp via satellite
3) Currents
4) Chlorophyll levels via satellite, anomaly plots
5) 3D image of the chlorophyll
6) Oxygen levels
7) Zooplankton levels
8) Fisheries-fish levels

The figures will be arranged in a manner that depicts the possible causes of this particular bloom, to how the bloom affected/is affecting the ocean ecosystem.

Hurricane Irene

Tuesday, October 11th, 2011

Team Hurricane Irene will make figures using data collected from both before and after the storm in order to see any changes that occurred. We are plotting temperature, salinity, chlorophyll, velocity of currents, water level from pressure sensors on the sea floor, changes in tides, and possibly others. We will use the heat equation to find the difference in heat between before and after the storm as well.
