One of the many beautiful sights surrounding our town is Observation (“Ob”) Hill. Hiking to the top, beautiful views of McMurdo station, Scott Base, and Arrival Heights surround us. The cross was left as a memorial to Scott and the members of his team who died on their return from the South Pole.… Read More
One of the scientific outreach / community engagement events at McMurdo Station is the Wednesday Night Science Lecture series. Dr. Chu gave an hour long lecture titled “A Decade of Shooting Towards the Stars- What Have We Learned?” The rest of our Arrival Heights team, Xianxin Li, Jackson Jandreau, Cissi Lin, and I (Amanda Steckel)… Read More
Mark Tolbert and Chris Haimberger from Toptica have met us in Antarctica! They will stay for 8 days to help us upgrade equipment and improve performance from our toptica lasers. We are operating these lasers, designed to work in well-controlled optical labs, in an extreme environment. We have to put a lot of care and… Read More
We enjoy taking colleagues from McMurdo base up to our lab for the occasional tour. Arrival Heights is an Antarctic Specially Protected Area (ASPA). Permits are required to enter the area and the amount of time we spend in the ASPA is tracked. This status is primarily maintained to keep the region EMI quiet –… Read More
Yesterday, we received replacement pumps for our Sodium Doppler Lidar’s YAG laser power supply chiller. First, we set up a testbed in the Crary lab field staging party area to set the pump we received to 60 psi. We then installed the new pump along with a motor, two water filters, and one transformer back… Read More
The Polar Star arrived in McMurdo sound this week. The ship is driving around the channel breaking up the ice for cargo ships that will follow and bring supplies for the winter season. Watching the ship ram the ice is a lot of fun. After the ice breaks up, seals coalesce around the newly formed… Read More
One of the main challenges our group faces is predicting the weather. Specifically, predicting when the clouds will clear from the top of Arrival Heights and allow us to collect data. We operate in optical wavelengths that can’t penetrate through clouds, unlike other types remote sensing instruments like radar. So at the start of every… Read More
The most surreal experience since we stepped off the plane was counting down the new year wearing sunglasses in the bright sunlight. At McMurdo base, they hold the largest music festival on the continent- Ice Stock. The official festival merchandise (scrawled on a hand-made cardboard sign) was BYO T-shirt so that the carpenters can paint… Read More
Merry Christmas! From December 22 to Christmas Eve on December 24th, we had clear skies and collected 50 hours of data. Working with our PI, we also did training sessions on the principles of how different components of the system work. On the iron lidar, we identified ways to correct the laser spectra on the… Read More
Merry Christmas Eve! The sky is clear, so we are on! We have learned how to power on & run the Sodium Doppler and Iron Boltzmann Lidars. They are running and we have been collecting data for over 24 hours. We will continue to collect data until the sky gets cloudy, pausing only for a… Read More
