Cooking on station and a 2013 re-post about South Pole water

My first Antarctic winter was in 2012. My blog for that season is: mikeontheice.blogspot.com  or click South Pole Mike to the top left.

It is now totally dark and the South Pole sky is alive. The barometric pressure has been very low. This affects the altitude. As pressure decreases the body feels a higher altitude. The physical altitude of the South Pole is 9,300 feet. This week the physiological altitude has been well above 11,000 feet which sometimes make simple tasks harder.

A few weekends ago was our sunset dinner and a two day weekend. Since the cooks worked the extra day for the dinner they had their two day weekend later. On Saturday three groups volunteered for Saturday meals. My group cooked lunch. My co-worker and I work seven days a week to support satellite schedule. 

I heated tomato soup...

along with grilled cheese sandwiches.

French fries.

Lunch time.

Sky sightings!

Many station activities.

We recently covered all windows with cardboard to eliminate outside white light which is detrimental to dark science. This window is across from the electronics office. I added the picture of my family.

Once again I am re-posting from 2013 about South Pole water as it has not changed.

For many years water at the South Pole was obtained by various energy and labor intensive approaches for gathering and melting snow. Until 1995 heavy machinery was used to gather snow and dump it into a mechanical ice melter. US Army Engineer Corps Raul Rodriquez developed a new approach to the ice melters. A well shaft is sunk 250 feet beneath the surface where heat is used to create a bulb shaped pool of warm water. Steam is generated in a sub-surface compartment and piped down to the well pocket. Water in the well cavity is always kept above zero degrees with the use of steam and thus the well cavity and reservoir expand over time to provide drinking water. 

A typical "Rodwell" lasts 7 years or until the well becomes too deep   and becomes energy intensive to extract the water. A new well is then developed. A Rodwell can provide up to 1 million gallons of fresh water before it becomes to deep to economically extract water. The South Pole is currently using Rodwell 3. This well provides the purest and oldest drinking water on earth as the current glacial ice is hundreds of years old.

Human waste is the only refuse not flown out from the South Pole. Sewage is pumped down the hole of the last Rodwell that was in use - it is essentially buried in the ice.

It is confusing to tell time in the Antarctic. Each country that has a station and "claims" territory uses their own time zone. The U.S. stations at the South Pole and McMurdo uses New Zealand time. The U.S. Palmer Station on the peninsula uses South American time.

My wife sent this space view of the Antarctic and surrounding winter sea-ice. The tip of South America points towards the
Antarctic peninsula. New Zealand and Australia are to the right.
