How Cold is Cold?

The coldest temperature recorded on Earth using a thermometer was -89.2C (-128.6F) at Vostok Station, in Antarctica, back in 1983. However,  my colleagues at the National Snow and Ice Data Center believe they found a temperature of -93.2C (-135.8F) near Dome Fuji (Antarctica) using the Landsat 8 satellite. There is a hope to establish an […]

Anemometers and Wind

Antarctica is a notoriously windy place.  The windiest place on Earth is said to be Commonwealth Bay, Antarctica, where winds often exceed 240km/h (150mph) and the average wind speed is 80km/h (50mph). The cold dense air that forms high on the Antarctic plateau can rush down to the coast at tremendous speeds under the force […]

Science Neighbors

There are only four (4) science groups at McMurdo during WINFLY. It is a very friendly atmosphere among the science teams as everyone understands the difficulty of working in Antarctica. Radio chatter will often be about conditions near various science camps or observations that could be relevant to each others projects… and the opportunity to […]

Snow

Antarctica is the coldest, highest and driest continent in the world. It is largely a desert, with most places receiving less than 250mm of water equivalent each year. Despite low precipitation, snow is often mobile at this time of year (September) due to unsettled weather, very cold temperatures and some very high wind speed events. […]

Fata Morgana

Polar regions can produce some interesting optical effects due to extreme temperatures and/or low sun angles. Yesterday was beautifully calm at Zodiac Camp and an inversion formed (i.e. when air closer to the surface is colder than the air above it – normally air temperatures decrease with altitude). The colder, denser air near the surface […]

Instrument Surgury

The scientific results from field campaigns are well reported in academic journals, often with text such as “measurements were taken during …”. However, the effort required to produce these results, including all the problems that had to be overcome, are rarely documented in full.   2odiac 2015 has not been a simple case of transporting […]
