Wave Event in Gulf of Mexico?
The flashing buoy I see is not in the Gulf of Mexico.
It’s way out in the Atlantic Ocean.
I’m thinking a malfunction of some kind.
East of Cuba now...
Godzilla poked his head out of the water while on his way to New York.
Could be a trench or something stirring things up ~
There was a 3.8 earth quake in the gulf south of Mobile yesterday. Hmmm.....
‘Bout gotta be caused by global warming, Bush, Sarah Palin, or the damn Republicans...everything else is
“Event Mode” is qualified as being within the past 24 hours. It’s not as if some wave action necessarily just set the thing off, it could have been as long ago as last night.
That area seems to be under an Atlantic Gale Warning....Could be a rogue wave, although I’m a landlubber and don’t know anything about that type of water.
Yeah, it’s east of the Bahamas and North of Puerto Rico.
It’s a DART (Tsunami detection buoy).
Shows some sharp oscillations in water height in the last three hours.
No notable earthquakes near it, though.
Most likely some sort of malfunction; if not the (remote) possibilities are a tsunami induced by an underwater landslide; I think an asteroid would have been noticed.
remember when that surfer dude rode the wave to gilligan’s island???
Yep! First time I ever heard the expression “dude”. LOL!
Now that'd ring some bells!
Eh, the data taken literally shows the water column height rapidly oscillating wildly by 60 meters in the last three hours, preceded by almost no motion at all; really seems a malfunction is most likely.
The measuring device is actually on the sea floor; the buoy is just for communications. So it shouldn’t be triggered by storm waves.
DART® systems consist of an anchored seafloor bottom pressure recorder (BPR) and a companion moored surface buoy for real-time communications (Gonzalez et al., 1998). An acoustic link transmits data from the BPR on the seafloor to the surface buoy.
The BPR collects temperature and pressure at 15-second intervals. The pressure values are corrected for temperature effects and the pressure converted to an estimated sea-surface height (height of the ocean surface above the seafloor) by using a constant 670 mm/psia. The system has two data reporting modes, standard and event. The system operates routinely in standard mode, in which four spot values (of the 15-s data) at 15-minute intervals of the estimated sea surface height are reported at scheduled transmission times. When the internal detection software (Mofjeld) identifies an event, the system ceases standard mode reporting and begins event mode transmissions. In event mode, 15-second values are transmitted during the initial few minutes, followed by 1-minute averages. Event mode messages also contain the time of the initial occurrence of the event. The system returns to standard transmission after 4 hours of 1-minute real-time transmissions if no further events are detected.
The bouy is reporting some really big waves.
It has been doing so for long enough that the bouys near it should also be reporting big waves.
Since this is the only bouy reporting these waves, it seems reasonable that the bouy is malfunctioning.
They are going to drive it right onto the turnpike and drive 10 miles under the speed limit in the left lane.
Weird, I just went out on the deck a few minutes ago and noticed the water was white-capping at night, with no noticable wind - trees are still.
