Müller Ice Cap Daily Report Thursday May 1

Daily Report for the 1 May 2025

Today was also a day of celebration as the Muller ice core became the longest ice core drilled in Canada. The previous longest ice core was the 335.7 m m deep ice core drilled on the Agassiz ice cap in 1977, followed by the Penny ice cap ice core from 1995, 334 m long, the Mount Logan ice core from 2024, 327 m long and the Devon ice cap core from 1998, 302 m long. A great cheer to all the heroes who have drilled these past Canadian ice cores. The Muller ice core is the first ice core drilled using drill liquid allowing selection of deeper ice thickness. The drill liquid keeps pressure in the borehole and prevents the deeper ice cores from breaking due to pressure difference between the ice and the borehole.

Drilling is just going so well and we celebrated during the evening making some snow sculptures.

 

What we have done:

-Drilled 19 runs from 328.13 m to 363.86 (34.73 m)

-Logged and O18 sampled bags 328 to 363

-Dug the Muller ice cap weather station free

-Repaired one of the Webasto

-Prepared the minilogger for the 70 m shallow borehole

-Made snow sculptures

Daily Report 25 March 2025   Yesterday, the first six of the Müller team reached Resolute. Weather is just perfect with temperatures around -25 deg C, no wind and blue skies. The team members are Dorthe, Emma, Linda, Shari, Grant and Dave We managed to sort out all the cargo and divide it in three piles. We also had meetings with PCSP and pilots. As we finished sorting the cargo we have arranged to fly to EUREKA tomorrow… wow very exciting. A great thanks to PCSP in Resolute for superb support and wonderful meals.   What we have done: -packed a storage box with cargo for the first 2 Twin Otters planned for 26 March and 1 April. -packed a storage box with cargo for the DC3 (Basler) planned for 5 April. -inventory of all cargo in Resolute. -meetings with PCSP and the pilots.   Dorthe Dahl-Jensen Wx at Müller: -30 deg C, wind sensor is frozen    Caption: Group picture in the PCSP Warehouse.

Getting ready to leave The forecast for tomorrow, Friday is good, sunshine all day, which we have not had all the days we have been here. Talking to Tom at PCSP at 7:30 am we hear that the plan is three pull-out Twin Otters tomorrow. Could not be better. THANKS Tom. As we don't really trust we will get good weather this report is written in the morning of Friday and the weather actually IS good. No wind and sunshine. We spent Thursday continuing the hand auger core at the Summit point and reached 6.6 m. The core consists of firn with ice layers up to 10 cm. The core has been sampled in 5 cm vials for stable water isotopes and a few melt layers have been sampled too for diatoms. We pulled the full drum with mogas and placed it 45 m west of the weather station, marked with two bamboo poles. ...

Over and out Saturday May 27 th , Dorthe and David made it to Resolute with the Twin Otter. Sunday May 28 th , Tamara started her journey south from Resolute, with the first mission to find the Lisa box, that never reached us, in Iqaluit. Irony was that a cargo plane delivered the cargo to Resolute the same evening… Tuesday May 30 th , Daniel and Niels left for Ottawa. Dorthe will leave Wednesday May 31 st and David Friday June 1 st . There are four planes each week going south with 20 seat each so it is not always possible to leave as fast a desired. We have had a good season and have successfully mapped the thickness and internal layers of the Müller ice cap. It has been a great and positive experience to be in the hands of PCSP – THANKS to all. Also, a great THANKS to the crews ...
