 Daily Report for 13 May 2025

Late in the evening we hit another milestone in the main core drilling, passing the 600m mark! Ice still contains lots of bubbles, which is very exciting, as it suggests it is from a time period with limited surface melting. In the firn-gas “suburbs” sample collection and measurements are also progressing, with two more levels sampled today. Finally, we also managed to ship out 36 ice core boxes to the freezer in

Eureka, both thanks to the Rod and Issy piloting and loading the Twin Otter -åå++++++++++++and the kind help of, Rachel, Dave, Igor and Sergei as well as Eureka personnel, including Don making sure our freezer was turned on. Thank you so much to all involved in this important shipment out of camp!

 

What we have done today:

- Drilling main core, drilled 16 runs from 573.91m to 600.83m (26.92m).

- Logged and O18 sampled bags from bag 574 to 600.

- Continued drilling of shallow core for firn-gas sampling, current depth: 11.5m. 

- Continued firn-gas sampling, two more levels sampled.

- Shipped ice cores to Eureka with two Twin Otter missions.

 

We are 13 in camp (Alison, Etienne, Iben, Rebecca, Fei, Richard, Nicholas, Tessa, Nerilie, Anais, Jamie, Julien and Bo)

 

Alison Criscitiello and Bo Vinther.

 

Wx at Müller: Mainly cloudy today with slight intermittent snowfall and a few sunny spells. Wind between 0 and 7kn from between 320 deg true 350 deg true, temperatures between -18 and -8 deg C.

Caption: Camp members still awake joined the late shift celebrating 600m: Jamie, Rebecca, Alison, Bo, Richard, Nicholas, Iben, Fei, Etienne and Julien. 


Caption: Bedrock bets no longer in the competition are crossed out by the loggers and drillers, this time Nicholas is the “eliminator”.


Caption: This is how to park a Twin Otter, in order to ease the loading of ice core boxes.



Caption: Richard, Rebecca and Alison improved on our food freezer – now with storage dug into the trench walls!

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 ...
