Here in Antarctica the weather is very important, as it was when Captain RF Scott and his men were at Cape Evans. Back in 1912 the readings were all taken using manual instruments, as can be seen in this image of Dr. Simpson taking the weather at Wind Vane Hill.

 

Today we have an electronic system which monitors actual wind speed and temperature as well as recording it on a chart. This is in the weather area of the Hatherton laboratory at New Zealand’s Scott Base.

During a big storm the needle on the wind speed meter can jump up 50 knots, or sometimes more. There is also a graph which continually records data. Some mornings, if it was windy through the night, I go up to the Hatherton Lab to see how strong the wind was. Last night we had gusts over 50 knots. There was a white out when I happened to wake up and look out at 3 am. Thankfully the wind died down as today was the day we packed to head out to Cape Evans.  More on that to come.

The first explorers to Antarctica came with a sense of adventure and purpose. They conducted significant scientific and meteorological observations as well as exploration. Today the main emphasize on Ross Island is science. Scott Base is supporting 75 scientific events this summer. Many science events are supported at US base McMurdo Station and there is also the Albert P. Crary Science and Engineering Center. While working at Scott Base we have the good fortune of attending talks presented by the scientists. This week we went to a talk at McMurdo presented by a joint US French group who are using super pressure balloons to take reading over Antarctica to assist in monitoring the ozone http://www.antarcticconnection.com/antarctic/science/aeronomy.shtml.

Early on in our stay at Scott Base (winfly) I joined some folks in a walk up Observation Hill.  Back then it was still dark after dinner but there was light in the sky from aurora borealis and a full moon so it was possible to see a lot. From high up Ob Hill we looked back at McMurdo Station and saw a bright green laser beam shining up from one of the research groups and then one of the high pressure balloons were launched. Spectacular!  It was nice to have the opportunity to hear what this balloon was doing up there in the sky.
