rising sea floor?
Gday guys, thought there'd be a few boffins on site or crew with some time and interest who may supply some theories on this?
maybe its crap or maybe it's a coverup!?
OCEAN FLOOR RISING BY 13 FEET PER DAY HERE
The National Oceanic and Atmospheric Administration website [link to www.ndbc.noaa.gov]
Has a Tsunami station in event mode activated for Station 55023 - STB Coral Sea located at 14.803 S 153.585 E (14°48'9" S 153°35'6" E).
The tsunami station has been in event mode since the large quakes occurred in the area for several days now. This is triggered by the buoys’ anomalies of water column height above the sea floor.
If you do a data search for 2010 March 20th to 2010 April 13th you get this-
Over 100 meters or 328 feet less distance from buoy to sea floor in 24 days!
That’s 13 feet per day since the quakes.
As you will see from the waves on the line graph it matches the tide lines perfectly
Coral Sea tide chart - [link to www.tide-forecast.com]
So Station buoy 55023 is still on the surface. Its not the lunar cycles, checked that as well.
There also has been a very odd sea surface temperature in the same location
See link CSIRO web page [link to www.marine.csiro.au]
Note the area in blue on the map on the left then see the unusually cold surface temperatures on the surface in the map on the right.
Seismic activity has also offers an insight as to what may be occurring
[link to aslwww.cr.usgs.gov]
Note the long time periods of S waves on this seismic station is the upward thrust of the ocean floor by 13 feet per day?
Is there anyone out there who can offer some science as to what’s going on in this area?

this would explain rising
this would explain rising sea levels?

sort of...
a very localised rise in sea floor level (say by rifting and sub-sea volcanism) would indeed cause an increase in global sea level but over the massive area of the oceans this displaced volume would only translate to a very small increase in overall sea level.
think of it rather as a shallowing of the sea depth in a local area by the uplift of the seabed.
could easily be volcanism with the strange current temps possibly correlating with convective currents caused by the suddenly hotter areas on the ocean bottom upwelling deep waters to the surface and vice versa.
anyone with specific knowledge of the area or the time to look into the specific data would be better placed to say tho.

i would put it down to
i would put it down to underwater volcanism. sounds like a case study i did the other week for yr11 geography. underwater hotspots are common around that area so it is a high possibility. ill have a closer look into it.

easy to work out boys, take
easy to work out boys,
take area in square meters thats risen less total areas of the sea floor on the planet that are sinking, and divide by total sea surface area on planet and times by meters rissen and will = close to nothing!
even if 10,000 sq km of ocean floor rises, it's ofset by other areas sinking plus the fact that the total sea floor is about 360,000,000sq km
ref: Surface Area of the Planet (510066000 sq km) Land Area on the Planet (148647000 sq km) 29.1% Ocean Area (335258000 sq km) Total Water Area (361419000 sq km)

less about sea level...
cheers Tony, all that makes good sense
however - i was hoping it might generate more theories on actual mechanisms for why the sea floor would be rising by that amount in such a short time. i'm sure anyone would agree that it's quite a remarkable rate of change.
good to see some numbers and interest tho. gues the all-consuming seal level mindset is hard to get around. lol
cheers

Hansie, if the areas on a
Hansie, if the areas on a thin crust fault line, then magma pressure from the motlen rock could easily move the crust up that amount.
When the las big volcanic erruption happened in South America, it was well documented that the whol moutain side swelled like a swollen belly before it let fly with it's ash, steam and moten larva.

all of these sites have reference to swelling of the earths crust pre erruptions or even major quakes.
