Gledelig jul and Merry Christmas! I hope everyone has had a peaceful Christmas, and stuffed their faces with all the good food and candy that belongs in this holiday. My Christmas was spent in Oslo (my home town) with my family; my mother, sister, her girlfriend and their dogs. Even though there was no white Cristmas this year, at least we had sun!
Some of you have messaged me and asked if I have quit blogging, since there has not been much activity recently. The answer is definitely no! I enjoy writing, and I get to do so many awesome things during this PhD journey that I love to share with you. In 2017, one of my new year’s resolutions will be to blog more frequently!
2016 has been a great year for me. During this first year of my PhD, I have learned and experienced so much. I wanted to do a recap post of all these moments, but I may do separate posts on some of the highlights later. Some of them definitely deserve that!
The moments and experiences are impossible to rate, so I will just list them in chronological order:
The last Saturday on the cruise was spent dismounting most of the equipment, while the ship laid still and drifting near the ice edge (where the transition from open water to ice is in the sea). The rest of the gear will follow the ship to Helsingborg, and be taken off during demobilization later in October. For myself, my equipment consisted of some cables and a laptop, so I managed to bring it with me in my bag.

The reason for me being on the Arctic Ocean 2016 research cruise is primarily to gather data for my PhD research work. I have promised a post about my work, so let me tell you a bit about what I am doing.
Yesterday, we saw the sun set for the first time in 38 days. We are headed south. The sunset is a sign; the journey coming to an end.

It finally happened – we saw a polar bear!
I got to help the meteorology work package with launching a weather balloon!
Taking cores from the sediments on the seabed can help researchers understand the (distant) past, how the earth looked like back then and how it became the way it is today.

Being on a Swedish icebreaker with a fantastic crew means learning Swedish traditions. We already had a surströmming party (eating fermented herring). Last Saturday, we got to participate in another Swedish traditional autumn party; kreftskiva (crayfish party)!

Illustration of the time zones of the world, where the earth is seen from the top (source).
The last week or so we have been doing bathymetric mapping surveys of the seabed in an area more west, close to Canada. We transited from the pole further south, to around 82°N 142°W, for these surveys. Transiting 7° south may not sound like much, but it is approximately 780 km (I wrote about the conversion between degrees and distances here). I was surprised by the noticeable difference in light.
I want to talk a bit about time zones and longitudes, which are actually a bit tricky up North. When you travel east and west in the world, depending on which longitude (breddegrad) you are on, there are different time zones. This is because night and day occur at different times in different places on Earth, due to Earths rotation. I assume most people are familiar with this. The first figure below illustrate the time zones of the world on a map of polar stereographic projection (the North Pole is in the middle, and the equator on the outer edge. I have another post coming up on maps can be tricky business in the Arctic.) You can see that the closer you get to the Pole, the closer are the lines/longitudes and therefore the time zones. Since the longitudes define the time zones, and the longitudes come together at the poles, the time zones in reality change a lot with small distances up here.
