With less than two weeks to go until the Atlantic hurricane season begins, it is time to dust off the equipment and make sure things are ready for any potential field missions this season.
One piece of equipment that we are putting in to operation this year is our newly developed Drifting Surge Cam (DSC). I first introduced it last month during the National Tropical Weather Conference in South Padre Island, Texas. The idea behind the project is to provide a live stream of storm surge from the storm surge. That’s right, the black box, loaded with an array of high-tech recording devices, will be placed out where the storm surge is expected to be significant enough to inundate the coastline. Instead of being locked down and attached to something, it will be allowed to drift with the rising water, going where ever the flow takes it. In essence, it will be part of the debris but poses no hazard to property or people (anyone not smart enough to have evacuated had better hope they don’t see it drifting by – that would be a really bad sign). The DSC floats on top of the water like an oil tanker, almost impossible to capsize. It is equipped with a live streaming camera that will provide a unique look, and sound, of storm surge as it happens. There is also a GoPro camera that will record incredible HD video for up to 13 hours.
In addition to the video aspects, the DSC will also transmit its location via satellite so that we may track it in near real-time. Seeing it move with the storm surge as it advances will be really interesting and should provide us with data that can help to understand how fast the water rises and what the debris flow is like. All of this from a perspective that would likely be lethal for a person to try to accomplish.
We tested the DSC in Galveston back in February with exceptional results. Tethered to a 100 foot rope, it was dragged out nearly 100 yards in to the cold Gulf of Mexico where 3 to 4 foot waves tried to capsize it. I could not believe how well it performed on its first test. The data and the video were simply perfect, totally exceeding my expectations.
Now, it is time to put it to another test. This time in conditions that more closely resemble storm surge.
We know that storm surge is a gradual rise in water as a tropical cyclone approaches land. The wind literally pushes the water on to the coast, rising more rapidly as the radius of maximum winds approach. The effect is similar to the tides, especially low tide coming in to high tide. At low tide, a lot more land is exposed that is normally covered in water. As the tide comes in, the water level rises and inundates estuaries, inlets, beaches, etc. On top of the rising tide are waves of varying height and period. There is also usually a local wind effect that helps to push the waves along.
The idea is to place the DSC in an inlet, Mason Inlet to be specific, right before the tide reaches its lowest point. From there, it does its thing while the tide slowly makes its way back in. Inch by inch, the water will rise and will eventually float the DSC. Once it goes buoyant, it should drift along with the current of the incoming tide. The inlet is perfect since there are ocean waves coming in. If all goes well, the DSC will end up near the back of the inlet, floating on top of the rising tide, bobbing along like a cork in a stream.
All the while this is happening, the DSC will stream live video, with audio, and transmit its location. This time, you can watch as it takes place. I will have a special page set up with two streaming video player consoles – one for the DSC, the other for our hand-held “everywhere” cam. This will give you a look not only from the DSC but also from my perspective along the shoreline. The entire test will probably take 4 to 5 hours. I am going to haul quite a bit of gear down to Mason Inlet and be set up for the duration. In fact, I also hope to fire up the Phantom quad copter to provide a live stream from the air as the DSC moves along in the inlet.
You will be able to track its progress via a link to our SPOT locator device which will update every 2 1/2 minutes.
Once the test is complete, I will process the video and the data to provide an assessment of how things worked out. The time lapse alone of the incoming tide should be really cool to see. Add to that the drift data from the GPS recorder inside the case and it completes a unique picture that can ultimately provide more clues as to exactly how storm surge works.
The test is scheduled for this Friday beginning at around 9:30 AM ET. I will Tweet about it and hope to answer your questions and take feedback along the way. The weather looks to be incredible all week long with Friday being seasonably warm. The water temp is in the low 70s which is a heck of a lot better than the Gulf of Mexico back in February. It should be an exciting day and I hope you can tune in from time to time to check things out.
I’ll post another update on the test Thursday afternoon which will include the links and the page that will have the live video feeds.
