Five small visitors in camp

One of our visiting birds took a rest in front of Grants tent.


After adjusting the tower alignment last evening, the borehole was logged. The logger was left in the deepest part of the borehole overnight to let the temperature equilibrate. Temperature at the bottom of the hole was measured at -7.9°C. After logging, three long ice cores were drilled today. With the borehole cleaned for ice chips, the drilling went very smooth.
As it has happened many times before, camp is also visited by birds this year. The visitors fall in two categories: The smaller birds that end up in camp by accident and that usually end their days here, and larger migrating birds (falcon, goose, snow owl) that just make a pit-stop. We are not quite certain about the species we have in camp now, but we hope that some of our readers will be able to tell from the picture. The birds were seen flying around camp several times, both as individuals and in a group of five. The birds also managed to wake up those sleeping in the dome at 5am as they triggered the polar bear radar. The radar indicated the speed of the moving object to be 6 m/s, so we figure it was indeed the birds. The positive side of the story is that if the radar can detect small birds flying around, it can probably also detect larger animals.

What we did today:

  1. Logged the borehole and drilled 3 ice cores.
  2. Logging depth: 2526.39 m. Processing depth: 2520.65 m.
  3. Physical properties measurement 2517.35 m.
  4. Worked on drill liquid level acoustic Pinger.
  5. Worked on borehole camera.

Weather today: Mostly blue sky, but cold and windy most of the day. Temperatures -24°C to -34°C. Wind 6-14 kt from W and SW during the day and calm in the evening. The forecast predicts -8C in two days from now(!). Let’s see.
