The Great Rideau Canal Pond Scum Patch

April 25, 2010 @ 17:17 By: gordon Category: Out and about, Photography

I was out for a walk along the canal earlier today. As I approached Pretoria Bridge I noticed there was something floating on the water. Getting closer, it became clear that this part of the canal is the Rideau Canal’s equivalent of the Great Pacific Garbage Patch, except for pond scum (mostly).

Rideau-Canal---scum-panorama---cropped Now, I know that the canal workers will be clearing this out as they do every year, but I was surprised at just how much there was. And I wasn’t alone in this – I heard a number of people talking about it as they walked along.

Not exactly the best thing, perhaps, for tourism, but at least the ducks seemed happy as they munched on it.

Just a reminder about the  information session to discuss the impact of the Gatineau Park Ecosystem Conservation Plan on climbing in Gatineau Park being hosted by the Ottawa-Gatineau Climbers’ Access Coalition at the MEC Ottawa Store this evening at 7:15pm. If you’re a climber, you need to attend this very important meeting.

Something I’d like to do

March 25, 2010 @ 16:58 By: gordon Category: General, Travelling

I’ve been fighting The Cold That Won’t Die this week, which has consisted mainly of sitting at home coughing and sneezing, interspersed by the occasional bout of dizziness, and all accompanied by a malaise. (Actually, I did go to work for part of the day yesterday, but the experiment was not a great success and it ended with a strong suggestion that I should go home.)

Anyway, to pass the time I’ve been thinking about something I’d like to do this summer. Coincidentally, the other day my friend Rob wrote about a couple of things he’d like to do this summer  and I was surprised to see that it’s really not that different from something I’ve been thinking about for the last year or so: namely, walking the length of Hadrian’s Wall.

Clever elevators

March 14, 2010 @ 12:07 By: gordon Category: General, Out and about

I was visiting someone in an old age care facility recently and was quite surprised with how cleverly the elevators there operate. The facility has two floors and residents are able to move about the facility pretty much at will. Access in and out is carefully controlled to minimize the chances of someone wandering off.

Some of the residents have Alzheimer’s. One of the characteristics of Alzheimer’s is a tendancy to wander. Thus, one of the goals when designing a care facility for people with Alzheimer’s is ensuring that there aren’t any dead end corridors that could end up frustrating them while they roam about. Elevators pose a special problem because of the potential for someone to get frustrated, or even trapped, if the doors close and they can’t figure out how to make them open again.

Some places use access controls such as swipe cards or keys to control access to elevators, but in this facility the elevators are designed to minimize this problem while allowing the residents to use the elevators on their own. Rather than requiring someone to push a floor button, they detect when someone enters the car and automatically go to the other floor where they patiently wait for people to exit. Very clever.

Brace yourself for a little sleep deprivation

March 12, 2010 @ 17:34 By: gordon Category: General

You’re probably going to lose an hour of sleep this weekend and there’s not much you can do about it. (Well, ok, you can sleep in, but you’re still going to be missing an hour.)

That’s right, Sunday morning at 2am most of North America switches over to Daylight Saving time in a futile attempt to save energy. As I’ve mentioned before, there’s evidence that energy consumption actually increases, as do accident rates in the week after the clocks are set forward.

I wonder if the slow drivers will be driving even slower on the Queensway next week.

Probably.

Why must they drive so slowly on the Queensway???

March 11, 2010 @ 16:55 By: gordon Category: General, Out and about

I’ve been grumbling about this for a while now and a couple of recent incidents have prompted me to stop grumbling about it in private and rant about it in public on the Internet (again), so here goes…

If you’ve driven on the Queensway, you’ve almost certainly encountered slow drivers puttering along below the posted speed limit for no obvious reason. The roads are clean and dry, it’s not raining or snowing, and there isn’t an accident or something else causing traffic to slow down.

They’re. Just. Driving. Slowly.

And chances are that they’re in lanes other than the right-most one.

“So what?” you might ask. “As long as they’re travelling between 60 km/h and 100 km/h they’re not breaking the law, so suck it up.”

No. Bzzt. Wrong.

One can actually use too much salt

February 17, 2010 @ 12:55 By: gordon Category: Environment, General

Salt is a popular way to get rid of ice that’s formed on sidewalks and roads. The City of Ottawa applies tonnes of salt to Ottawa’s roads and sidewalks every winter. So much, in fact, that a few years ago they started using brine solutions and pre-wetting the rock salt because both are more effective than dry rock salt and result in less salt being use, which is a Good Thing.

From a driver’s point of view, salt is both a blessing and a curse. A blessing because it results in safer roads and a curse because it can damage cars. From an environmentalist’s point of view, it’s a real problem because it can have a serious impact on the plants and animals it comes into contact with.  From a building owner’s point of view it’s also a a mixed blessing: No ice means people aren’t going to sue you, but at the same time it can quickly damage concrete and cement.

But some building owners seem to be sacrificing the longevity of their buildings at all costs. Last week, one building I walk by every day on my way to work had almost a solid layer of salt on all of the steps and walkways. Salt was building up in the corners and you could see it creeping up the concrete, outlining every crack and crevice. Yesterday, I noticed bright new patches of rust on some of the railings that were caked in salt, so it’s starting to eat away at them, too.

True, the building has absolutely no ice problems, but that less because of the salt and more because there hasn’t been a lot of ice this winter. If they keep this salt application strategy going, they’re not going to have much of a building left.

I’m wondering how they’re going to clean up all their salt when spring finally arrives. Hopefully, they’ll be responsible and scoop it up to be used next winter rather than getting the pressure washers out and washing it down the storm sewers. Already you can see trails from the runoff from their property leading to the sewers.
