Much of our time since we’ve arrived has been spent unpacking, setting up, and testing our gear and attending training sessions and meetings with the Raytheon support personnel.

All 4 of our Aerosonde unmanned aerial vehicles (UAVs) survived the trip to Antarctica, and have been setup and test run on the loading dock of the lab.

The Aerosondes are relatively small, with a 9 foot wingspan. Despite their small size they are capable of flying through strong winds (they were designed to fly through hurricanes), which is good as we expect to see close to hurricane strength winds at Terra Nova Bay, where we’ll be conducting our science flights.

The temperature has remained below 0 F since we’ve arrived. The warmest temperature has been -4 F and the coldest, in McMurdo, has been -36 F yesterday. The past few days have been both cold and windy.

This video was taken from the Crary lab loading dock on Sunday morning. The temperature was -30 F and the wind was blowing 30 mph.

Sunday was particularly cold and windy, with wind chill temperatures down to near -70 F. Despite the cold weather myself, Nick, Peter, and Paul took a walk to Scott’s Hut, located just north of McMurdo. The hut was built as part of Sir Robert Falcon Scott’s Antarctic expedition in 1902. We’re hoping to get a tour of the hut tomorrow afternoon, as no unescorted groups are allowed to enter the hut to ensure that the historic artifacts are not disturbed.


A clear contrast between the old and the new – Scott’s Hut and McMurdo Station.

While the weather is one aspect of coming to Antarctica at this time of year that I’ve really enjoyed on this trip, the other is seeing the transition from the long polar night to the long days of summer. Since we’ve been here the length of daylight is getting noticeably longer. When we arrived last Wednesday sunrise was at 10:53AM and sunset was at 2:59PM. Today sunrise is at 9:41AM and sunset is at 4:08PM, giving us more than 2 hours more daylight now than just a week ago. By September 21st we’ll have 12 hours of daylight. Once the sun rises on 19 October it will not set again until 24 February.

In many ways, everyday life in McMurdo isn’t too different from life back in the US. We live in dorms, that keep us well insulated from the cold. The dorm rooms are setup to accommodate 2 people per room. I’m sharing a room with Dave. There are communal bathrooms on each floor of the dorm, and each dorm has a TV lounge room.


Dorms

Our meals are prepared for us and served in a cafeteria in building 155 (all of the buildings here are referred to by numbers). Meals include breakfast, lunch, and dinner as well as a midnight meal called Mid-Rats for people that work the nightshift.

There are two bars (Gallagher’s and Southern Exposure) and a coffee house in McMurdo.

We are able to go to a gym that includes cardio equipment and weights. The only problem I’ve found in going to the gym here is that I find it very difficult to put on my big parka after working out, since I’m usually very hot and sweaty. I’ve taken to walking the 100 yards from the gym to my dorm in just my shorts and T-shirt after a work out. This is fine, even with the temperature down near -30 F, although my T-shirt did freeze stiff during the less than 5 minute walk back to my room the other day. At least the cold weather makes it easy to cool off after a workout.

We spend most of our time in the Crary lab, which contains offices as well as lab space.

Unlike my office at home I have a very nice view from my office down here, which overlooks McMurdo sound (covered with sea ice at this time of year) and the Royal Society Range of the Transantarctic Mountains across the sound.

This afternoon we visited the Berg Field Center food room, to get food to stock our hangar at the Pegasus ice runway.

The drive from McMurdo to the runway takes about 30 minutes, and if the weather becomes too bad we will need to stay out at Pegasus, rather than risking getting stuck trying to drive back to town. Weather conditions here are classified as conditions 3, 2, or 1. Condition 3 is considered normal weather and there are no restrictions on travel. Condition 2 is defined by stronger winds (48 to 55 knots), a wind chill temperature of -75 to -100 F, or visibility less than 1/4 mile. During condition 2 weather you are required to check out with the firehouse before leaving town. Condition 1 weather is the worst weather, with wind speeds greater than 55 knots, wind chill temperatures less than -100 F, and visibility less than 100 ft (often due to blowing snow). During condition 1 weather you are not allowed outside and off base travel is not permitted. If we happen to be at Pegasus when condition 1 weather occurs we’ll need to stay there until the storm ends. If we are driving between Pegasus and McMurdo and get caught in condition 1 weather we’ll need to stop where we are and wait in the van until the weather improves, since it is too easy to get lost and drive off of the road in whiteout conditions.

Now that the last flight to Antarctica, until the end of September, has been completed, we are now cleared to start setting up at the Pegasus runway. We are planning on going out to Pegasus tomorrow to begin setting up our office space. Our hangar will be a large tent, and is going to be setup by the carpenters later this week. That should be ready for use by the end of the week. Once that is setup we’ll be ready to start our flights. I’ll include some photos of our facilities at Pegasus on my next post.

Rye Rover Rivals Real Rig http://icestories.exploratorium.edu/dispatches/rye-rover-rivals-real-rig/ http://icestories.exploratorium.edu/dispatches/rye-rover-rivals-real-rig/#comments Mon, 29 Dec 2008 23:21:18 +0000 Jean Pennycook http://icestories.exploratorium.edu/dispatches/?p=1418 MCMURDO STATION, ANTARCTICA– Eighth grade science students at Rye Middle School in Rye, New Hampshire, got into the act in Antarctica. Under the direction of their teacher Robin Ellwood, they built a submersible robotic camera that was launched in the Ross Sea.

Ms. Ellwood, a veteran science teacher, is also an accomplished ice diver working with a science research group in Antarctica’s Dry Valleys. Headed by Dr. Peter Doran from the University of Illinois, they are studying the fresh water lakes of that remote region. The lakes form primarily from glacier runoff, as it rarely snows and never rains in this part of the continent.

This year the team brought down the Endurance, a large robotic camera and data collector, or ‘Bot’ as it is affectionately called. Gathering data in larger amounts and in a shorter time than humans could do from the surface or diving, this sophisticated machine will map the floor, and provide water analysis of these remarkable lakes. You can learn more about their project and see pictures of the Bot here.

Not to be left out of the project, the Rye students designed and built their own robotic camera which had to be able to function in the extreme cold salty water of the Antarctica ocean. Getting the neutral buoyancy just right and using materials that were appropriate in Antarctica’s fragile environment provided many challenges, but all were well met.

“ScubaDoobaDoo” was successfully launched in the ocean and took its first underwater video in the Ross Sea, Antarctica, November 2008. Its performance was outstanding, it was easy to maneuver and the videos were excellent, reported Ms. Ellwood.

The students can be very proud of their accomplishment. The students’ project was funded in part by the school’s PTA.

ScubaDoobaDoo’s camera in front uses the LED light source next to it. Under the ice in Antarctica it is not only very cold, but very dark. The switch box houses the controls: right and left motors for turning and forward and back motion, the top motor for up and down motion. The video is sent to the DVD player through the 100 foot cable attached to the camera.

Next to the Bot, ScubaDoobaDoo was overheard saying “When I grow up, I want to be like him.” He is well on his way.

Beneath the Bridge http://icestories.exploratorium.edu/dispatches/beneath-the-bridge/ http://icestories.exploratorium.edu/dispatches/beneath-the-bridge/#comments Sat, 20 Dec 2008 21:16:30 +0000 Exploratorium Crew http://icestories.exploratorium.edu/dispatches/?p=1343 MCMURDO STATION, ANTARCTICA– (By Ron Hipschman) Sometimes, when walking around McMurdo Station, one can encounter some interesting things. When we walk from the cafeteria to our office in Crary Lab, we take a little bridge to get over some pipes. In over a week of crossing that bridge many times a day, I never noticed what was lurking beneath.

Walkabout http://icestories.exploratorium.edu/dispatches/walkabout/ http://icestories.exploratorium.edu/dispatches/walkabout/#comments Tue, 09 Dec 2008 20:12:56 +0000 Exploratorium Crew http://icestories.exploratorium.edu/dispatches/?p=1280 MCMURDO STATION, ANTARCTICA– (By Ron Hipschman) In this video I thought it might be interesting to give you a sense of McMurdo by taking you from our office in Crary Lab, where most of the polar scientists do their work, on a short journey outside to see where we’ll be webcasting from (weather permitting!)

Today we did our first test webcast just to try a new setup that we’ve never used before. While we have our traditional broadcast equipment, we’re trying to make ourselves more mobile by substituting a Mac laptop and video production software called WireCast for 350 pounds of electronics in two large racks. It is hoped that the smaller and lighter equipment will be faster to set up and easier to use in remote locations where we could not bring the bulkier racks.
