Kettle Hole Expedition II – pano and vids

As promised, a little more visual info from the great bog outing.

First, a panorama of the open water area of the bog. Side note: I downloaded and tried Hugin as a panorama stitcher (the source pix were taken w/o any assist – I can never find the pano mode on the camera and it has never done me much good anyway) and found it to be really quite excellent.

A video of me settling in to the mat, posted mainly for the sound of the water percolating up as I sank down.

And two videos of the mat undulating, the 1st mild and the 2nd a bit more wild.

Kettle Hole Expedition

I’ve known about our local kettle hole for many years, but for no good reason, have never visited it. I fixed that yesterday. It’s an amazing place; I know that there are kettles and potholes elsewhere that make ours look like a teacup, but think about the size of the ice chunk that made this landform. Impressive.

You first see the bog itself through the trees – lots of oak and some pitch pine as befits the very sandy soil – at the bottom of a steeply sloped dish. Most of the bottom of the kettle is a quaking bog, with some open water at the center (and around the perimeter). Here’s a shot of the bog showing the open water edge and, through the trees, the black spruce growing on the mat:

And a shot from the mat, back at where the picture above was taken:

On the mat, Sarracenia purpurea:

Expect a second post soon with video of the bog quaking (I hope) and audio of the water gurgling through the mat as yr humble correspondent stops and settles (again, I hope).

Seacoast Makers Viv How-to

About dang time I posted on this!  A couple weeks ago I did, as part of a Seacoast Makers outreach effort, a naturalistic vivarium how-to talk (otherwise known as a frog-and-pony show) at a favorite local plant place, Wentworth Greenhouses.

Yr humble correspondent, gesticulating.

It went quite well – decent turnout and no one fell asleep. I went through a viv build from start to finish: enclosures, substrate, backgrounds, lids and lighting, plants and, finally, animals. As you can see above, I brought a 16″ cube and (on top of the cube) a small carrier with a Phyllobates vittatus inside. The Ranitomeya ventrimaculata Iquitos Red that inhabit the cube are shy at the best of times; no way were they going to show themselves after a car ride.

Good Tuftian that I am, the slide show was just that – a bunch of photographs loosely related to whatever I was talking about. Luckily -strike that- By design I have accumulated quite a few build documentation pics and they were put to good use. I thought about posting the presentation here for download, but I think for the moment I’ll make it available on request: if you’d like a copy of the presentation in .odp/Open Doc Presentation format, send along an email addy or share a Dropbox folder with me and I’ll get you a copy.  A few of the slide images after the jump.

The Bathyscaphe Trieste and Captain Don Walsh, USN Ret.

With all the hubbub over James Cameron’s planned dive to Challenger Deep, a little attention should be paid to the  first and, at this point, only people to make it to the deepest point in the ocean: Auguste Piccard and then-Lieutenant Don Walsh. They did it in 1960 on the bathyscaphe Trieste.

The Trieste was, essentially, a dirigible. It was mainly buoyancy cambers filled with gasoline (here water:gasoline::air:helium) supporting an untethered bathysphere; there’s a huge difference in compressibility between liquids and gases, so I’ll leave the blimp vs. zeppelin distinction alone. *saunters away, whistling*

The point of this post is an interview NPR did with Capt. Don Walsh. I was blown away. Check out his Wikipedia bio – adventure scientist extraordinaire – and yet in the interview (unsurprisingly), humble and thoughtful. I’d encourage folks to give him a listen either at the NPR link or here (right click and save the mp3 locally).
