This is footage from inside the NOAA NWS Forecast Office in Norman on May 20, 2013. I believe this is primarily footage of the office during the Newcastle-Moore tornado. They did a really good job warning the public!

It may be too late to find a safe place.

NOAA Weather Radio

I was listening to the NOAA Weather Radio feed from Louisville, KY on Friday and this is what I heard. No lie.

The Bloop

NOAA has recorded several unexplained sounds while monitoring underwater ecosystems and activity. This sound, dubbed The Bloop, was recorded in the summer of 1997 by the Equatorial Pacific Ocean autonomous hydrophone array. Multiple sensors over a spread of about 5000 km were able to pick up the sound. The general location of the sound comes from 50oS, 100oW. Below is the spectrogram of the sound.


Although the origins of the sound are unknown, there are speculations as to the source as well as what isn’t the source.

Let’s start with what isn’t the source (or what is hypothesized to not be the source): man-made objects or events, familiar geologic events such as an earthquake or volcano, or an animal (despite the sound resembling animal-like sounds, it is many times louder than the loudest animal on the planet, the blue whale).

So what is it? Well, NOAA’s Dr. Christopher Fox at speculated that it was a result of ice calving in Antarctica, which is the sudden breaking away of ice. However, many people, including Dr. Fox about a year later, are speculating that the sound is in fact of animal origins. Will we ever know? I’m not sure. It would be interesting to find out the source though!

NOAA Harmful Algal Blooms →

I was browsing NOAA recently and I came across this section that, well, caught my eye. They have an entire section devoted to harmful algal blooms! If you’re interested in this sort of stuff, then check this site out.
