Hurricane Sandy Tide Levels

Just in case you haven’t heard, there is a giant storm heading towards the East Coast of the United States caused by Hurricane Sandy. If you need more evidence that something is going to happen, you can check out our tide level data that we collect from around Cape Cod, Massachusetts. Storms of this size affect all kinds of weather system data such as pressure, temperature, and tide levels. A recipe for anticipating a major event is when you see the pressure drop and see a change in the amplitude of the tide levels. As you can see below, the tide levels are shifted upwards by 15″ to 20″. Please, stay safe! We will do the same thing as we button-down the hatches at ioBridge HQ.

Hurricane Sandy Tide Levels in Cape Cod

At one of the marinas, we have a security camera setup running off of an APC battery backup system. Here’s what really high tides look like.

The system is running an ioBridge Gateway with connected battery-powered sensors over an XBee radio network. The tide level sensors are MaxBotix ultrasonic level sensors.

Tide Sensors, Hurricane Irene, and the Internet of Things

As we announced last year, we have been running tide level points around Cape Cod to more accurately alert boaters about high and low tides. Our tide sites are connected to the Internet via the ioBridge platform. We also provide real-time alerts and tweets to boaters in Cape Cod and surrounding marinas.

One of our many TideAlerts.com subscribers had the idea to “watch” the tide levels during Hurricane Irene. After analyzing the data, we observed something interesting. The period of the tides did not change, but the amplitudes (the high tide and low tide marks) were greatly exaggerated as Hurricane Irene passed through Cape Cod.

The ioBridge tide project is another example of how the Internet of Things is emerging. We started this project 3 years ago and it provides an extremely useful service and is only possible by aggregating tons of sensor data and sharing it with users, developers, and researchers. This application is based on open data from NOAA and users monitoring environmental information and tries to find more meaning than just being a collection site of data.

By the way, here is what the tides looked like during Hurricane Irene at one of our public monitoring sites:

The good news is that by the time Hurricane Irene made it to Massachusetts, the storm was weak and all of our tide sensor sites survived.
