Müller Ice Cap Daily Report Tuesday April 22

 Daily Report for the 22 April 2025

 To change from dry to wet drilling the borehole needs to have a slightly larger diameter to allow the drill to move up and down through the liquid. After implementing the improvements to the drill software program we rimmed the borehole fishing all the cuttings up by drilling small ice cores as plugs. We ended the day by logging the borehole with the mini logger to follow the temperature and ensure the borehole is plum.

While preparing for wet drilling in the main camp Ali, Etienne, Jaime and Sofia went out to the Mountain View shallow drill site a few hundred meters away and drilled 36 m with the Eclipse drill. Jaime and Sofie drilled their first ice core 😊

 

What we have done:

-Drilled 36 m with the Eclipse drill at Mountain View

-Rimmed the bore diameter up to 129.6 mm in preparation of the

 wet drilling. Drilled from 96.01 m to 99.66 m

-Logged, weighed, O18 sampled and ECM measured bags 97- 99.

-Calibrated minilogger and logged the 100 m borehole

-made a box around the compressor of the Viessmann freezer

- prepared hose and liquid handling systems for the borehole

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 ...
