I’ve finished two sculptures made from 3D scans of the Antarctic landscape so far. This latest one is of a ventifact — wind-eroded boulder — that I photographed in the McMurdo Dry Valleys, a trip I recounted in an earlier blog post. I call it the “Bird” Ventifact because from certain angles, it looks like a giant beaked bird with a crest.
In addition to its lively, birdlike presence, part of what attracted me to this form was its concavities and holes, worn by the abrasive action of volcanic gravel carried by fierce Antarctic winds. If a successful sculpture is judged by how it transforms as one walks around it and takes it in from different vantage points, this ventifact certainly works as sculpture. By capturing it in 3D, I’ve “brought it home” for others to experience as an object and not just as a series of flat photographs. Looking at one side hardly predicts what you’ll find on other sides:
In order to capture the complexity of the form, with all its undercuts and hollows, I chose 3D printing over CNC routing, because the router bit only moves up and down in one direction, and does not tilt to get other angles. 3D printing, by contrast, is additive, and builds the form in layers, preventing the undercuts from collapsing during the printing process with temporary supports that can be broken off once the print is finished. Since the 3D printers that I have access to only have a capacity of about 8 x 8 x 11 inches, and my finished sculpture is 16 x 29.25 x 29.25 inches, I had to print it in sections, epoxy it together, and smooth the joints between the pieces before painting it. However, I was able to assemble the 25-odd pieces into a seamless whole. I’ve made this short video of the process. Watch it full screen and see it come together:
It’s my third day at the Cape Royds penguin colony, which consists of Adelie penguins. It’s a relatively small colony, with the larger ones at Cape Crozier and Cape Byrd, and Beaufort Island, which are all less severe environments than Cape Royds, which is basically further south. Katie Dugger, who has been keeping track of the banded birds this season and their nesting activity, estimates that there are a little less than 2,000 breeding pairs, i.e. 4,000 penguins. The ones that haven’t bred go out to sea, but will come back after the chicks have hatched. Right now, at any given time, about half of the birds are on land and their mates are in the water. The eggs have been laid, so they’re swapping places sitting on the nest about every other day. Katie knows this from keeping track of the banded birds. Chicks are banded at the end of each season.
To get to the colony, you walk about 5 to 10 minutes down a trail past one of the historic huts used by Ernest Shackleton’s Antarctic expeditions. Like other historic huts in the area, the hut and the artifacts and supplies left behind by those early explorers some 100 years ago are maintained and conserved by New Zealanders. The huts are kept locked, and you may only enter with a trained hut guide, who could be a New Zealander or an American. I didn’t come with someone who had the training, so I haven’t been in, but if you’re curious, another photographer with the Antarctic Artists and Writers Program, Shaun O’Boyle, did a lot of shooting in there. I highly recommend his blog Portraits of Place in Antarctica. He got here in October and just left. His project involved the architecture and manmade structures here, and he does beautiful work.
It’s a protected area, so not anyone can enter. Right now if you watch the penguins, their activities revolve around nesting. They’re either sitting on a nest, occasionally standing up to shift position and settle back down. Or they are picking up rocks in their beaks to add to their mate’s nest. Or they are in the water or coming and going from the water to eat krill and silverfish, their main diet.
When they go in the water, they tend to form little groups, then walk to the ice edge together and enter together. They just join whatever other penguins happen to be on their way down the slope to swim.
It’s entertaining to watch them dive into the water. They gather at the edge, mill around a bit, and then they dive in. Here are a couple where I’ve stopped the action:
So, friends and blog followers, yesterday I figured out how to shoot video with my Nikon SLR. I’m getting better at it as I go along, so I have some good footage already, but the Internet upload speeds are sloooowwww, so I can’t just put them all up at once. My first effort is admittedly not in as good focus as the ones I made today, but it gives you a look at penguins in action nonetheless, and they are, frankly, adorable. You can find the video on YouTube here. As I get them online, I’ll note them in this blog, or just subscribe to my YouTube channel. And of course, Jean Pennycook has posted a lot of photos and videos of this colony at PenguinScience.com.
