"Dirty Snow"


 1-28-2020

Herbie came to visit Sunday. Both of our airports experienced weather condition 1 on Sunday. For condition 1 to exist you must have winds greater than 55 knots, or wind chill colder than -100 F or visibility less than 100 feet. I’m happy to report of the 3 we did not have -100 degrees! We did however have the other two. The most amazing part of it all is that we had very benign conditions in town. It’s a reminder to all of us here how quickly the weather can change and how arbitrary it can be where and when it hits.

At lunch today I had the pleasure of listening to an NSF (National Science Foundation) representative. In a former life he was one of our C-130 pilots. He was telling me that both Williams Field and Phoenix Field, our two airports, had to be moved last year because the snow had gotten “dirty”. Dirty snow attracts more heat and causes the runway surfaces to become unstable for use. Ah, the things you must deal with in Antarctica! I’m really happy that as I’ve gotten older, I’ve learned to listen more and talk less (yes that’s my wife you hear laughing). It’s amazing what you can learn if you just listen now and then.

Cargo Ships and Whales

  2-7-2023 Ship change…The first cargo ship left port last night and the next ship pulled right in behind him and began off-loading. Because of that, our Yacht Club meeting was cancelled because our Commodore was pulling line duty on the ship change. (For non-nautical people it means he was handling ropes used to tie the ship up to the pier) Because of the sun falling further in the sky it now feels like dawn and dusk all day. The first sunset is February 20 th , the day I leave McMurdo. The days are also getting cooler.   It’s not too bad when the wind isn’t blowing. If I can stay awake, I can visit the McMurdo Museum which is open from 8:00 to 10:00 this evening. The Minke whales are in the sound in large numbers. Last night I watched a pod of about 12 swimming around. It’s fun to watch them all “blow” as they surface. The Orcas are also still around. Penguins stay near the ice edge and are in jeopardy. All the seals are near Scott Base away from the ice edge and danger.

The Delta

  12-6-2022 The Delta The transition from land to glacier has gotten almost impassable for vehicles, even those with the largest of wheels. One of the vehicles that can still make the passage is called “The Delta”. Remember watching “earth movers” when you were a kid? They had a huge tractor like front end connected to a large trailer that scraped dirt into itself.  Wow, that wasn’t a very good description, but I hope you know what I mean. That’s kind of what a Delta is except it’s designed to haul people instead of dirt. I’ve attached a picture to help your imagination. That’s what I rode on this morning getting to work. If you like roller coasters, you want to ride in the very back of the passenger compartment. Every bump and turn are magnified to the point that if you don’t have a seat belt on you may well bounce your head off the ceiling.  The other interesting thing is on the inside of the Delta, instead of graffiti people put stickers on the walls and ceiling. I’ve included just

Scott Hut

Image
  10-29-2022 Tomorrows supposed to be very cold and windy (50 mph) so I went for a walk down to Hut Point after work today. The hut was built in 1902 but on the outside, it looks like it did the day it was built. I’m just stunned by its pristine appearance. Outside the front door is a seal that was left there when Scott abandoned the hut over 100 years ago. The seal has remained frozen in place since that day The Hut was open to the public when I was last here but because people were removing artifacts, they now keep it locked. Tours are available on given days and a volunteer docent answers questions and ensures artifacts remain intact for future generations. As you enter the building, you’re forced to duck your head in order to enter through the very short door. When you enter you feel as though you have literally stepped back in time.  Socks and t-shirts are draped over the bunk beds. Blankets and sheets lie rumpled as though the men had just rolled out of bed. A penguin, the object
