ODAS ?

[Colin24]

Below is an extract from a chart correction
pertaining to one of my 2000 series Imray charts.
Straight forward enough. My question is: what does ODAS stand for or mean?
There are two other such buoys marked on this chart and nowhere in the legend or list of abbreviations does it explain what this means.
I've looked on the admiralty chart and there is no mention of them at the same position.
Someone please put me out of my misery

Something like:-

Oceanographic Data Acquisition System

Posh name for a tide recorder.

Since when was Shotley anywhere near an Ocean???

That's close enough for me.

Thanks very much, it was driving me nutty.

As others have said, they are for gathering oceanographic and meteorologic data. One thing I can never understand is how they are moored in such deep water - there is one in the Gulf of Lions that is in 2240m of water. That's a lot of cable for a little bouy to support.

I could not find your buoys on this site <A target="_blank" HREF=http://www.ndbc.noaa.gov/station_page.phtml?station=62103>http://www.ndbc.noaa.gov/station_page.phtml?station=62103</A>, but I think the Channel Light Vessel temperature sensor needs a look at -
Air Temperature (ATMP): 6.8 °F
Wind Chill (CHILL): -18.6 °F

previous readings were stable.

Positioning critical

if you've had much to do with Lion - it's one of the most extreme, changeable micro-climates in the world.

<<< is how they are moored in such deep water >>>

Don't know about the Gulf of Lions one but typically they are moored with polypropylene line (which is buoyant) and ss wire if the mooring is mixed. If there are large waves to be catered for (as is typical if it is a wave rider deployed to measure big waves) they will include a compliant section such as rubber bungee.
