My blog posts are mostly about places I've been - this one is about places I've only just found out about, and I don't expect to be visting them any time soon.
The in-flight info system on my trans-atlantic Air Canada flight (where I'm sitting typing this - although I'll post it a bit later) tells me more about where I'm flying over than any other in-flight system I can remember using - it feels like I've discovered a whole new layer of geography (apologies to my geography teachers from many years ago if they told me this).
I've just passed over the Porcupine Bank - and I'm now heading towards the Charlie-Gibbs Fracture Zone. Some of the other places I can see on screen are the Immarssuak Seachannel and the Great Meteor Tablemount. I knew there were lots of geographic features under the North Atlantic - I've just never known what any of them were called, and since this is an Air Canada flight, I even know what some of these features are called in French (Rive de Porc-epic, Chenal de Immarssuak and Butte du Grand Meteor).
Suddenly there are an awful lot more place names to think about.
