I'm thinking of perhaps doing areas like from Inverness round to Ullapool
for example...? Inverness to Dundee? Dundee to Berwick etc?

Any thoughts on how many areas would be feasible? They have to be able to
attract a reasonable amount of data.

I would go Firth of Forth - Farnes - should not be much variation and
you have a large amount of divers.

For the sound of Mull, you get all of Oban, maybe up to Fort William,
down as far as Seil Island?

Not sure where the various flows come in (North Atlantic, Irish sea,
North Sea) for the North - maybe pickup a tidal flow atlas to have a
look at.

Alternativly, there used to be a satellite which monitored such things...

http://www.a1surf.com/surfcheck-watertemp.html might be linked into it.

Just wanted to point out, the link to your company www.inva.co.uk doesn't
work (or rather, the site isn't visibl

I'd hazard a guess that the big variance is caused by the depth the
measurement was taken at.

In the winter months, it's going to be much the same temp at the
cockpit as it it at the hydrobox (i.e. brr!).

In summer, the top will warm up but the bottom still stays pretty
cold.

Maybe if people enter the depth then you can figure out a cool way
of displaying the deep/shallow temps?

OpenGL plugin for netscape perhaps, complete with rendered
underwater terrain :)

Classy, I guess you could also knock up a java app to do it.

Ah now, that's where you'd be wrong. They are actually dynamically created
using the GD library as supplied with PHP....

....I just love playing with stuff like that.

Anyway, I had thought about adding depths the readings were taken at, I
might get round to it this year.

I guess YOU could! I would be more than happy to host it...

Ahh, depending on the access you have to the server, consider taking a look
at GNUPlot, it is very flexible in what it can produce, more than GD IIRC
(at least, more than GD at the time) about 18 months ago I wrote a bunch of
psuedo-realtime charting tools for work using php and making calls to
GNUPlot, if you want them, i'll dig them out and mail them to you.

I used a lot of the smoothing functions which might come in handy for this
project.

Right, I've had a look and I can pretty much do any stats you want, I dunno
how to interpret them but seeing as you suggested it you can answer the
following questions...

On the full year page I reckon you want to see...

- Full year max
- Full year min
- Full year mean
- Full year median

and for each month

- month max
- month min
- month mean
- month median
- month stdev
- month variance?

Then on the month page

- month max
- month min
- month mean
- month median
- month stdev
- month variance?

and for each day

- day max
- day min
- day mean
- day median
- day stdev
- day variance?

Does that sound about right?
