Where is the water?

Here is a picture of me in the field. Gregg and I went to sample the upland ponds last week. Chris was supposed to come with us, but he was too sick. It turns out that he had the flu and spent two days in his room under quarantine while we were out enjoying two days in the field. I had not been in the field since November for my annual Thankgiving trip, so it was great to get out to do some field work.
On the first day we flew over a some ponds that we had not sampled before. I thought we were in the right spot, but everything goes by so fast in a helicopter compared to when you are walking. I asked the pilot to set down near the ponds. After spending half an hour there, thinking "this does not seem right" I decided we were really not in the spot we intended to visit that day. Gregg and I proceeded with the sampling and mapping of the ponds in the area and expanded our data set in the process. When we finished the sampling, we sat down to take a break and sample our flight lunches. I don't recommend the swiss steak sandwiches.
We decided to return the next day because we had requested another day of helicopter support to get to another set of ponds. We went back to the ponds at the terminus of the Marr Glacier that we had intended to sample the first day. These ponds are at 800m elevation (or 2600 ft). It has been a season of stormy weather and somewhat unusual amounts of snow fall. Our ponds were mostly covered with snow. One of our projects was to map the perimeter of the ponds to estimate the current size. It was complicated, we could not see the ponds because of all the snow. We were able to walk around the flat area, occasionally kicking through the snow with our bunny boots to confirm that we were still on ice and not soil. I think we did fairly well.

We did find some liquid water to sample in the ponds that were at a lower elevation. We also found some liquid water where streams were flowing into or out of the ponds. Some of these ponds seem to be fed only by local snow melt and others have glacier streams feeding them. This little pond fills a small depression and seems to only have snow as a source for water. The water was also tea colored because of all the algae growing there.

Ponds

I have been a blah blogger this year. The internet had a recent "upgrade" so it's no longer painfully slow. I have a couple of pictures from the upland ponds that (I think) deserve a chance to be seen. I took these photos on my last trip to Taylor Valley when I fearlessly crossed Lake Hoare following in Rae's footsteps. (It was scarier on the way back.) It was worth the scary part though, to hike up onto Andrews Ridge and see this lovely pond.

Hopefully my team will make a day trip to the ponds near the Marr Glacier soon. These ponds behave very much like the lakes in the valley bottom. They wax and wane, depending on the summer temperatures and the glacial melt that feeds them. They accumulate salts over time. As you can imagine, this pond fills a depressions in the landscape, so water flows in, but it does not flow out. Water leaves by evaporating and sublimating off the surface. Some of the ponds do have small streams flowing out to other ponds. We have been studying these ponds recently to better understand their hydrology and chemistry.

Sketchy weather

These pictures are from a few days ago. No matter, it looks about the same today, minus the snow on the ground. There was a bit of snow flying earlier today. It's one of those summers. I'm very curious to know what is controlling our weather this season, if it's some kind of shift in the SAM (southern annular mode) or just normal sketchy antarctic weather. It has not been a warm and sunny summer. It's not a "Big Melt Year". There has been no "flood". Today we learned that the road onto the sea-ice has re-opened to large wheeled trucks, not just track vehicles. It has been cold and cloudy so the road is firming up and the wheels don't sink in. Tomorrow the forecast is not looking good. Three of our co-PI's are due to head south, so hopefully the storm does not develop as promised.

I think I should go for more walks, but then when it's grey and snowing and blowing, a trip to the Coffee House is more appealing. The coffee house does not look like much from the outside, but inside the atmosphere is cozy. They serve coffee and wine, so the coffee house is also known as the "wine bar". It's a relaxing place to go in the evening for a glass of wine or two and a chat with friends and co-workers. As my friend Rhoda says "It's always condition 3 in the office." And that sentiment applies to the Coffee House too.

Coffee is an important part of life for many people here. Besides the fact that many of us are caffeine addicts in our regular lives anyway, we work hard here and coffee is a nice way to take a break and feel recharged. It's also a social thing. For me it's nice to make and drink coffee as part of my normal routine here. Because we all eat in a cafeteria, and therefore do not cook our own food, it's nice to prepare the coffee in the morning and then to drink it!
