Global Warming?

Posted by: Adam Meredith on 30 April 2005

After the recent heavy rains I have noticed that the ducks, swans and coots that live on the many waterways around Salisbury have been "sitting" lower in the water. Some of the smaller birds showing only a neck and head above the surface.

Could it be that their buoyancy has been reduced by a dilution of the rivers?

An amateur naturalist.

I saw a couple of ducks sitting outside the building where I work yesterday as I walked in. I thought this was very disturbing.

Salisbury is being increasingly terrorised by gangs of ducks with attitude. They make the Swans look cuddly.

An argument for ID cards for waterfowl?

Adam - you'd never get the bill through parliament.

The waterways would be freshwater rather than saltwater so the only positive effect of the increase in rainfall would be a dilution of pollutants in the water.

And diluted water would make them sit higher in any case, improving their buoyancy.
I'm sure they're laying in wait, timing the moment just right so they can pounce.
Then you're the sitting duck.
A couple of seasoned duck hunters should be able to take care of this in short order.
Hell, just let them know I'm coming. Anytime I've ever gone to the lake sporting a hunting license and shotgun there isn't a duck in sight.

Well, I live inland so for me it's normally all water off a duck's back....

Glad someone took me seriously.

No problems - they become immobile at night, warmed by their repressed sense of injustice, on the banks and walls along the river.

God help Salisbury if they get head-torches!

Perhaps they are all overly fully from the old ladies swarming the banks in the Maltings no?

Last weekend our neigbour drove down to Salisbury for a picnic.

He's a bit of a "toff" is our Julian. Drives a beautifully restored Morgan in brilliant red. Wears the cloth cap, yellow scarf and tweed jacket....and of course, a pair of yellow driving gloves he's borrowed from his dad. He likes to make his girlfriend smile by roaring around the country lanes, and he's always excessively polite to the village yokels when passing through their villages.....

I digress

Last weekend he pulled up rather sharply at a ford, just outside Salisbury. As Adam has mentioned, it had been raining pretty hard last Saturday so our Julian was a bit apprehensive about driving through this ford.

Fortunately, leaning on a fence, not too far away, was a village yokel. So our Julian gives him a jolly "ahoy! old chap" to get his attention "How deep's the ford, my good fellow!"

"Bain't more thaan 3 inches zorrr" comes back the lazey reply with a broad smile....

So our Julian slips her into first and roars forward with a cheery old wave of the hand to the yokel...

Only.....the cherished old Morgan dives up to its gun'wales in flood water and our julian and his girlfriend are lucky to get out in one piece.

Dripping from head to toe, with his girlfriend in tow and the pair of them a bit out of sorts, our Julian squelches back to the yokel.

"I say old chap" gasps Julian "you told me this water was only 3 inches deep. I nearly drowned and my lovely car is ruined. What on earth made you say 3 inches!!"

"well zorr" replied the yokel "I don't rightly know...but the water only comes half way up our ducks!"

Cheers

Nice tale, shame about the motor though ! At least it wasn't salt water wassit.

Or shallow?

I suspect that Salisbury ducks are of an increasingly higher density. It's the only logical explaination. There are more ducks than people round here - they seem as buoyant as they ever were. And the ducks are at the same height.

Reminds me of the following:

Why do ducks have flat feet?

To stamp out fires.

Why do elephants have flat feet?

To stamp out burning ducks!

Thanks Jon.

I just sprayed coffee all over my monitor.

Freshwater has a lower density than saltwater, hence offers less buoyancy for ducks, humans or anything else.

JonR, have you posted the SP on your experience with the 282 and 250.2? If not, get on with it old son, the world awaits!

Salisbury is not on a tidal river, so the water is always fresh water.

Of course, after a storm, this freshwater might be "slightly" less dense because it will have a higher percentage of surface run-off water, Particularly if this run-off water has

a) more air trapped in it
b) less disolved mineral salts because it hasn't percolated through the underlying limestone/sandstone etc

But i doubt if this effect would be enough for Adam to notice.

But if he had seen the ducks just after they had eaten really well for a day or two, and increased their density before growing bigger, well then, its possible that Adam might have noticed them sitting lower in the water.

...........but what has this got to do with "Global Warming". After all, April has a history of heavy showers.......

Jeeez bazz you remembered?? Eek Smile

Don't worry, a review will appear in Hi-Fi Corner very shortly!
