While we have a weather station that records variables including temperature, wind speed, wind direction, visibility, and the height of the ceiling, we often have back-ups and different methodologies for crosschecking the output of the weather station. The video in this post summarizes one such check.

Often measuring the height of the ceiling, or clouds, can be difficult and the instrumentation can record improper information if snow is blowing or if there are high winds. Since the height of the ceiling is vital information for pilots, we often check our weather station readings against that of a weather balloon. Enjoy this video of me launching one of these balloons that we used to measure the height of the ceiling! I am now an honorary weatherwoman at WAIS Divide.

MCMURDO STATION, ANTARCTICA– The last couple of days have been really busy down here at McMurdo. I’ve been going through a lot of training sessions and have had many meetings with our Team. We’ve been trying to get all of our equipment together for the long journey across the sea ice to New Harbor. It’s a really long process to make sure we have everything we’re going to need at the field camp.

But today I had some free time in the morning. The weather was incredibly clear and crisp. I took the opportunity to climb up Observation Hill.

Observation Hill.

Observation Hill is a large hill that is 750 feet tall next to McMurdo Station. It is commonly called “Ob Hill” by the people who live and work here. It is the most climbed peak in Antarctica. The hill was named by Captain Robert Falcon Scott’s Discovery Expedition when they explored this area of Antarctica between 1901 and 1904. Members of Scott’s team would climb to the top to make weather observations.

The further I got up on Ob Hill, the better the views became. I could see all the way across McMurdo Sound. I could see Mt. Discovery (right), Black Island (left), Brown Peninsula (low, and in the middle), and the Royal Society Range of mountains (not shown) as they stretched to the north as far as the eye could see. The straight line on the ice was the roadway that I traveled on from Pegasus Field just a few days before.

As I climbed higher and higher, it became windier and colder. Snow was blowing around and I was glad I brought my thick insulated gloves and my ski goggles with me. With the cloudless blue sunny sky above, I bundled up and continued up to the summit.

Almost to the top.

Finally I got to the top of Ob Hill. I gazed down on McMurdo Station 750 feet below me. It looked like a tiny town. There are fewer than 1000 people here now, with more on the way. The population will grow to nearly 2000 during the height of the summer season. I’m amazed at how efficiently this small community runs to support the lives and activities of the people who venture down to the white continent. Looking down at McMurdo Station from this vantage point reminded me just how isolated we truly are down here.

There’s a giant cross that was erected on the top of Observation Hill to honor Captain Robert Falcon Scott and the members of his expedition who died on their return traverse from the South Pole during their Terra Nova expedition between 1910 and 1913.

Scott and his men got trapped in their tent on the Ross Ice Shelf during an unusually long storm. They were already very weak and they ran out of food. When they got trapped, they were only 11 miles from a depot where they had enough food to get back to their camp on Ross Island. On the cross that Scott’s men built is an inscription from “Ulysses” by Alfred Tennyson which reads: “To strive, to seek, to find, and not to yield.” These words are inspiring to me. I will try to not cease my own efforts to understand future climate change. To do this, I am in pursuit of knowledge of the past climate on the continent of Antarctica.

This place is so stunningly beautiful. Everywhere I look away from McMurdo Station I see various shapes of dark grey rocky peaks covered with white snow and ice. That or the smooth, flat ice of the Ross Ice Shelf and the lumpy sea ice floating on the surface of the Ross Sea in McMurdo Sound. It’s easy to get lost in the sheer expanse and isolation of this wilderness. But focusing on the details of the shapes, the way snow blows over a mountaintop, or how the sun moves around the sky in a circle gives perspective on singular aspects of the beauty of Antarctica. I can’t wait to get out into the field, to be away from “civilization” in town, to see new views of this other world.

There are constant reminders here of past exploration. Looking to the north from the summit of Ob Hill I could see Hut Point at the end of Hut Point Peninsula. The peninsula sticks out 15 miles to the southwest like a little finger off of the side of Mt. Erebus. There, a cross memorializing another fallen explorer and Scott’s Discovery Hut.

As I descended Ob Hill to get back into the warmth of my room, I snapped one more photo of the wind-swept Mt. Erebus. The smoke and vapor coming out of the top of the volcano, and the snow and ice crystals being blown across the landscape show me how dynamic this environment is.

The glorious day turned into an amazing night. Seeing the sun dip behind the Royal Society Range around 11pm was a rare picturesque treat. Our last sunset here will be on October 21st. After that we’ll just watch the sun circle around the sky, neither rising nor setting. It will just roll around the heavens all day.

Tonight’s vivid scenery was accentuated by thin wispy clouds illuminated by the setting sun behind Mt. Discovery. I had to go outside and take some photographs. I could get used to this place!
