Just found out about Chet Van Duzer’s Sea Monsters on Medieval and Renaissance Maps, a new book out this month from British Library Publishing, which explores the monsters drawn on maps from the 10th to the 16th century. From the publisher:

The sea monsters on medieval and Renaissance maps, whether swimming vigorously, gambolling amid the waves, attacking ships, or simply displaying themselves for our appreciation, are one of the most visually engaging elements on these maps, and yet they have never been carefully studied. The subject is important not only in the history of cartography, art, and zoological illustration, but also in the history of the geography of the ‘marvellous’ and of western conceptions of the ocean. Moreover, the sea monsters depicted on maps can supply important insights into the sources, influences, and methods of the cartographers who drew or painted them.

I may have to get this.

The Nebula Awards were handed out last night. The ceremony ran late and it was held in San Jose, California this year, so we were up far past our usual bedtime to watch the webcast: it was after midnight, our time, by the time they started giving away the polymethyl methacrylate cuboids.

Here is a list of the winners; it’s been reposted many other places, so it’s not necessary for me to do it again here.

I was happy to see two of my favourite stories win awards: Aliette de Bodard’s “Immersion” (short story) and Andy Duncan’s “Close Encounters” (novelette). Nancy Kress’s After the Fall, Before the Fall, During the Fall wasn’t my pick for novella, but it probably would have been my second or third choice. As for best novel, I haven’t read 2312 yet, but it ought to be in the imminent Hugo voters’ package. I’ve only read about half the nominees so far, and on that admittedly limited basis I’d have given it to The Drowning Girl by Caitlín R. Kiernan. That said, I’m still looking forward to reading The Killing Moon by N. K. Jemisin, because I tend to like her stuff a lot (it’s on my bookshelf, but I’m behind: I can only read 80 or 90 books a year, you know).

As for handicapping the Hugos on the basis of these results, reply hazy try again. The de Bodard, Kress and Robinson may well be the favourites going into the Hugo voting, but they’re up against a different field: only two novels, three novellas, one novelette and one short story have made the final ballot for both awards (Duncan did not make the Hugo ballot). I’ll be looking at those Hugo nominees soon. Well maybe not soon — this is me, after all — but certainly before voting closes. Probably.

The latest new species to arrive at our bird feeders appears to be the Pine Siskin (Carduelis pinus). It’s a passerine finch that resembles the goldfinches and redpolls we see more frequently. Like goldfinches and redpolls, they flock in substantial numbers: I counted more than 20 of them today. More photos here, here and here.

The earthquake that hit eastern Ontario and western Quebec this morning had its epicentre awfully close to us here in Shawville, Quebec. Which is to say — despite Toronto’s usual best efforts to make the earthquake theirs — that we felt it here sooner, and possibly harder, than the rest of you. Both the Ottawa Citizen and the Canadian Press include quotes from Shawville’s mayor, Albert Armstrong, who described it as unlike anything he’d ever lived through before, and he’s lived here all his life.

I haven’t experienced many earthquakes (the last one was in June 2010) so it’s hard for me to compare; this one felt, well, wobblier than others, like I was in the backseat of a car driving along one of Quebec’s finer highways on a hot day with the windows up, and if it doesn’t stop soon I’m going to barf. That kind of motion. One person said I’d tweeted about it before anyone else (at least that she saw), but then I was at the keyboard when it hit; all I had to do was command-tab to the Twitter app and type one word. The quake lasted more than long enough for that.

Natural Resources Canada lists it as a magnitude 5.2 quake and puts the epicentre 18 kilometres northeast of Shawville; the USGS calls it a magnitude 4.4 quake and locates its epicentre 19 km north-northeast of here. I’ve pinpointed the two organizations’ epicentres, showing the differences, on this map.

Either way, the epicentre was situated in the rural municipality of Thorne, which I should say something about, because it usually doesn’t get much attention. It’s sparsely populated, with fewer than 300 permanent residents (an 18 percent drop over the past 20 years); the seasonal population of cottagers is more than three times as big. It’s Shield country (hence the earthquake) and so not good farming, but it had an influx of German settlers in the late 19th century whose main legacy is an Oktoberfest held each October in Ladysmith, Thorne’s centre. (Seriously, try the wings at the Hotel Ladysmith.) The arrival of a small cohort of American draft dodgers has made the joint much more interesting in recent decades.

National Geographic Daily News looks at recent research that fingers the African Clawed Frog (Xenopus laevis), a common laboratory research animal and aquarium pet, as the source of a deadly chytrid fungus, Batrachochytrium dendrobatidis, that has devastated amphibian populations worldwide. At one point amphibian declines were attributed to a number of factors; apparently the focus has sharpened somewhat since I last heard about this. Via Kingsnake.com.

Update, May 20: Nature’s coverage fingers the use of Xenopus in pregnancy tests; once the test was obsolete, hospitals released the frogs, carrying the Bd fungus, into the wild …

It’s a big skiffy weekend, what with the opening of the new Star Trek movie and the season finale of Doctor Who. Spoilers abound.

It’s often argued that spoilers should have an expiration date. No one, for example, should feel the need to put a spoiler warning on the fact that Darth Vader is Luke Skywalker’s father, because The Empire Strikes Back came out on May 21, 1980 — 33 years ago. So there is a point at which spoiler alerts are no longer required, and people who complain about spoilers can be rightly ridiculed as solipsistic weenies.

But what is that point after which spoilers are fair game? Nathan Fillion thinks that spoilers shouldn’t apply to the previous season — which is to say, if season five is being broadcast now, season four is fair game. (It’s true that a lot of the complaints come from people who are several seasons behind, catching up on DVD or Netflix or iTunes.)

Me, I think that if you’re sufficiently invested in a TV show, movie or book that spoilers would affect your enjoyment of it, you have an obligation to consume that cultural product as soon as possible.

Which is to say: if you want to watch Star Trek: Into Darkness spoiler free, get your ass to the movie theatre this weekend. If you don’t want to be spoiled about “The Name of the Doctor,” make a point of watching it on broadcast TV Saturday night or, if like me you don’t have cable, download in from iTunes on Sunday.

Make a damn effort, in other words.

I think opening weekend is about the only spoiler-free window you’re entitled to. The following week, we’re gonna talk about stuff — about Benedict Cumberbatch’s Star Trek character, about who Clara Oswald is, about the Doctor’s name. If that’s too soon for you, then it doesn’t matter to you enough. Get a move on, or shut up.

The Cassini team has released a global topographic map of Saturn’s moon Titan. What makes this map interesting is the fact that, due to its thick atmosphere, Titan can only be mapped by radar during Cassini’s close flybys. As a result, only half of its surface has been imaged, and only 11 percent has topography data. For this map, the remainder was, well, extrapolated:

Lorenz’s team used a mathematical process called splining — effectively using smooth, curved surfaces to “join” the areas between grids of existing data. “You can take a spot where there is no data, look how close it is to the nearest data, and use various approaches of averaging and estimating to calculate your best guess,” he said. “If you pick a point, and all the nearby points are high altitude, you’d need a special reason for thinking that point would be lower. We’re mathematically papering over the gaps in our coverage.”

Topo maps of parts of Titan have been released before, but not for the entire moon. See previous posts on The Map Room: Titan in Stereo; Topography of Titan.

Google announced a complete redesign of Google Maps at their I/O developer conference yesterday. The new maps are vector-based, take up the entire browser window and change based on the context — highlighting certain streets, for example, based on a search — and your usage patterns. It’s also apparently quite resource intensive: these are maps designed for fast processors and fast Internet connections. It’s just an invite-only preview at the moment. For coverage see Engadget and The Verge.

Yikes! The Nebula Awards will be awarded this Saturday — at 10 PM EDT. So I’d best hurry up and get the last of these posts about the short fiction nominees finished. I’d meant to have them done more than a month ago, but, you know. Life.

In this final installment I look at the novelette nominees. Novelettes are the middle length, running from 7,500 words to 17,500 words. (If you missed them, here are the posts about the novella and short story nominees.) This year there are some novelettes on the ballot that I just loved, which is atypical for me; usually my response to novelettes isn’t quite so enthusiastic. (But that’s not to say that my response is normally tepid. I’m just a miser with my superlatives.)

So what is the situation with cardinals in the Ottawa Valley?

A decade or more ago, when I was living in Ottawa, I was given to understand that Northern Cardinals (Cardinalis cardinalis) were a relatively recent arrival to the area — that their range was, thanks to climate change, gradually moving northward. Fast forward to today — or rather, yesterday, when a cardinal arrived in our yard, the first one either of us had seen, anywhere. (See photos above.) I announced the fact breathlessly on Twitter, but it doesn’t seem to be as big a deal as I thought. Apparently cardinals are a common sight in Ottawa — how long has that been going on? Granted, we’re further up the Valley, so if the range has been moving northward slowly, then they may just be turning up here now. Or am I mistaken? Are cardinals a big deal around here or not?
