Milky Way as seen @AntarcticaNZ Scott Base. Not much light pollution down here

Aurora australis intensifies at South Pole; at top, Southern Cross & pointers, Alpha and Beta Centauri. View towards the dark sector: silhouette of South Pole Observatory at center, red light at left, IceCube Neutrino Observatory @NSF @SPTelescope @uw_icecube pic @iceman_90South

Aurora Australis (southern lights) over the hitching rail (where we plug in our vehicles to keep them warm) @AntarcticaNZ Scott Base. Can't get over the colours

Sun dog with Mt Erebus to the left. Ice crystals in the air refract the light to make it look like rainbows @AntarcticaNZ

Beginning its 61st winter, here’s McMurdo Station in the moonlight; in the distance, the lights of the new Phoenix Airfield on the ice shelf. Saturn and Mars appear close together in the center of the sky, days after their conjunction, pic Jeff Warneck @NSF_OPP @NSF

Time lapse looking down on @AntarcticaNZ Scott Base from the wind farm site.

Antarctic sea ice extent averaged 3.53million km2 for March, not far below 1981-2010 average of 4.03million km2 for that month. The minimum extent for the austral summer was reached on 20 Feb, after which sea ice grew rapidly, esp in Amundsen Sea bit.ly/ObOCzV @NSIDC

New study involving BAS researchers suggests warming oceans could put seabirds out of sync with prey #albatross #seabirds #climatechange bit.ly/2GzMpte

Orcas up close! If you're in Auckland NZ, tomorrow, 6pm Thurs 5 April, come to this event at AUT University, Dr Regina Eisert of University of Canterbury shows rare video of her very close encounters with Killer Whales on the sea ice #Antarctica bit.ly/2IqH7Rn

Watch how measurements of ice thickness change from @esa_cryosat, can been used to measure the rate of grounding line retreat in #Antarctica. Great job Dr Hannes Konrad! @SEELeeds @ICASLeeds @NERCscience

Satellite data @esa_cryosat shows ice sheet is losing ground, esp in West #Antarctica, eroded by warm ocean water circulating beneath its floating edge. Most accurate map yet of ice sheet’s submarine edge (grounding line) around 16,000km of Antarctic coast bit.ly/2H5PGSk

The @Keeling_curve is 60 years old! daily record of CO2 in air. 1st measurement in 1958? 316.19parts per million. In 2013, CO2 measured at Mauna Loa surpassed 400ppm for 1st time in human history. South Pole became last place on Earth to surpass 400ppm in 2016 @Scripps_Ocean @NSF

"The race to understand Antarctica" by @FT journalists @pilitaclark and Charlie Bibby following their visit to Rothera Research Station earlier this year ft.com/video/5f7fa3dc…

If you read just one thing this week, be sure to make it this excellent @FT feature by @pilitaclark about her recent visit to Antarctica with @BAS_News ft.com/antarctica

Antarctic Winter School 2018 Sea Ice: The thick and the thin of it. Join a group of likeminded people in the Catlins for the weekend and listen to leading sea ice researchers explain the role of sea ice in the global climate system. bit.ly/2mr7mfY Photo by Fiona Elliot

Aurora over Scott Base in the early hours of this morning. Twilight lingers as we head towards our final sunset in about 4 weeks @AntarcticaNZ

Killer whales up close - Dr Regina Eisert presents her research findings from her recent field trip to Antarctica: bit.ly/2uoyJzT @AntarcticaNZ @UCNZscience #Orca #KillerWhales @Kelly_Tarltons @NZTCV @AlisonBallance
