Buoys will be buoys

A tsunami buoy placed in April NW of Australia started recording reduced water column height on 24 August.
Placement in April had 4612 ish meters of water below.
24 August measured 4580 m
29 August saw a drop to 4473 m
Currently sitting on 4233 m & stable

Folks - either this buoy is totally haywire or the sea floor under it has risen over 376 m in the last month.
Data here

:scared:

I would give my eye teeth for some satellite coverage of this area above these readings:
YYYY MM DD HH MM SS Water column height (m)
2012 08 29 17 30 00 4580.468
2012 08 29 17 29 00 4515.955
and again here
2012 08 29 18 00 00 4510.221
2012 08 29 17 59 00 4575.758

is that a big splash back or what??
Note to self: Do not go fishing around that buoy.
 
"SuspiciousObservers" on Youtube has mentioned this in a few of his daily news videos. Here are his recent mentions that I know of:

In the following video he checked the data on the two other buoys in that area and found that one of them shows a drop in sea height (which must mean a rise in sea floor) of 20 meters. So it seems something really creepy might be going on down there.

The next day, he took another look at the buoy, and the sea floor had risen by over 40 meters, according to the data.

Interesting.
 
Hmmm... Wouldn't that be in or near the "infamous" Java Trench?

The Java Trench is a deep underwater valley running long the coast of Java and Sumatra in Indonesia. A trench is actually the deepest part of an ocean even though it is relatively close to the coastline. The deepest part of the Java Trench is 7,450 m (24,442 ft). The islands in this region are mostly the tops of large underwater volcanoes that have slowly grown out of the ocean over time.
[...]
The geologic activity around the Java Trench has resulted in some significant (infamous) events throughout history.
In 1883, the island of Krakatoa started belching out gas, ash and steam and eventually erupted violently on August 26. When the dust settled the island was completely gone. The volcano almost completely destroyed itself and caused 40 m (130 ft) tsunamis that traveled across the ocean leveling villages. The sound of the eruption was heard across the ocean 4,800 km (3,000 miles) away. The explosion is considered to be the loudest sound ever heard in modern history. In 2004, a magnitude 9.1 earthquake occurred in the Java Trench. It was the third largest ever in recorded history and resulted in over a quarter of a million deaths as a result of earthquake and tsunamis.

I checked, and you're right. It's about 50 miles/60 km from the trench. That's pretty creepy.

You can see the bouy here, it is in th center, labeled "53046 - South Bali" if you hover your mouse on it:

Here's hoping Java doesn't get any surprises.

I watch this every day - It's kind of in my back yard, although thankfully have Australia in between us.

Station 53046 had another kick yesterday - 14:22 on 15th shows a spike in water column height from 4235 to 4259 and steadily dropping to 4216 as of now. Something definitely lifting the sea floor down there. Dropped to 4202 while I was typing this!!! :shock:
 
I requested an update from Australian Bureau of Meteorology following the cessation of data from this buoy on 18th October. The response:

"The South Bali Buoy, numbered 53046, has been producing erroneous readings since mid August.
We are investigating the cause of this, which is likely due to the buoy and associated pressure sensor unit on the sea floor being dragged by a vessel. To avoid concerns from anomalous observations data, the feed has been switched off until the issue can be resolved. In the interim tsunami monitoring and warning observations data can be obtained from two nearby buoys numbered 56001 and 56003.
Regards
Bureau of Meteorology"

I can buy that a ship may snag the buoy mooring anchor & drag it away from deployed area. A buoy could be moved a considerable distance in that event.
In the diagrams I can see, the bottom pressure recorder unit is completely separate to the buoy, sitting on the ocean floor at approx 4000-5000m down & communicates with the surface buoy via bi directional acoustic link.
I don't understand how a passing ship can interfere with the pressure sensor on the floor (too far down) or how the potential dragging of the buoy away from the original location would screw the pressure measurements calculated by the pressure unit.

I am admittedly not a scientist and now quite puzzled. Would it make a difference in the pressure readings if somehow the sensor is on it's side or upside down? It has buoyancy floats attached for retrieval purposes, so maybe badly damaged? Happy to be educated on this as I have reached the end of my own line of logic. I starting to consider sabotage by blue whales.
 
According to Suspicious Observers the other day, the buoy was checked and then returned to an area a few miles away from its original location, where it is continuing to register rises in the sea floor.

Yes he did. According to the data from the buoy, the water column height has fallen over 1km in a little over a year. As the sea level hasn't changed significantly in the area over that time, it means that the sea floor has risen by that amount.

Here's the data:
