Second day during our transit trip from Helsingborg to the Ice edge


I am sitting in the lounge area in the starboard mess on Oden, enjoying the calm wavy movement from the ship, while we are traveling along the coast of Norway - heading up to the north. We were really lucky with the weather yesterday - there was a high risk of us getting into a low-pressure system with rain and thunderstorm, but we travelled just within the warm sector of the front, with the wind and avoided most of the rain. This gave us perfect conditions for working on the deck and installing instruments on our foremast and the weather station on the 7th deck. 





In the morning we set up the 3D sonic anemometer (see the photo, the instrument on the top of the mast that looks like a tripod for the camera). This instrument is an accurate instrument, that sends sound waves that get received on the opposite side by the receiver (on the picture you can see three metal sensors inorder to get the whole 3D flux in the horisontal and vertical direction). It measures temperature and wind, which then gives us surface fluxes. We are especially  interested in the the eddy-fluxes (turbulent fluxes) in the vertical direction, and with this sonic we can then measure sensible heat fluxes. We also mounted the other sensor, a Li-Cor, a lidar flux instrument (looks like an ice cone, located next to the sonic on top of the mast), measuring fluxes as CO2 and moisture, which then gives surface eddy-fluxes such as latent heat fluxes. Of course, there was a lot of cables involved and we had to secure all the cables with Cable-ties - this was a fun job! It was like doing a sewing project but with a bit bigger strings (here cables) that you had to secure onto the mast in a nice way so that it does not get tangled or messed up by the wind.







In the afternoon we fixed the weather station on the 7th deck - also a lot of cable securing of course! We mounted the rotronic (temperature and humidity sensor)-looks like a torch on the figure-mounted parallel to the vertical metal mast, the radiometers for measuring incoming solar and thermal radiation (they are on the horisontal plate with a scale that cancels out the movement of the ship so that the instruments are always directed upwards) and an anemometer (the cup-wind instrument, pointing out on the edge of the railing) measuring the 2D horisontal wind and a GPS sensor (next to the anemometer). We also mounted on both side of the ship at the rails Infrared temperature sensors, that are directed to the surface down from the ship in order to measure the surface temperature. 

So it was a busy day as well, with small rain showers but mostly pleasant weather to work outside. Apart from the physical work we need to do, we also have daily sea ice meetings during this one-week transit period, where we discuss important issues related to the work on ice. It was during this meeting we could for the first time sense the ship swinging to the waves! Some of us that potentially would get seasick were wearing bracelets that helps for seasickness, and they really seemed to work! I am happy I don’t get seasick (or I hope I won’t ;) ) :)




In the evening after dinner and our daily evening meeting, I gave a beginner lession in Lindy Hop, kindly assisted by the other lindy hopper Frank - I was soo happy that so many showed up, eager to learn to dance Lindy Hop! I really enjoyed it - seeing others having so much fun gives me so much joy! Also there were really quick in learning and I got asked several times after the session when will the next class be :) I hope to continue with the classes during this trip, it is a nice and happy evening activity after a day of hard work. Especially now during the transit most of us don’t have that much to do, so why not dance? We finished of by dancing out on the Helipad. It was a lovely evening! Later on we all met at the lounge and enjoyed some cold, alcohol free drinks, played some card games, laughed a LOOT and just relaxed after a perfect day on Oden.

I hope we get the sounding station set-up today and maybe in the evening we’ll dance again - haven’t missed any evening of not dancing!

NorthPole Celebration (Monday eve 16th) & Ice Station B (Sun-Mon 15-16th) and Ice station C (19-20th of August)

Image
As usual, the past four days has been adventurous - and history has been made (dancing on the Norhpole to live music)! For today’s blog, I want to tell you about our two last super ice stations (station B right before the North Pole and station C, which is ongoing right now), and the big North Pole celebration. In between the ice stations we had some calm days - transit to the next stop on Tuesday, as well as transit and a few CTDs on Wednesday. The ice conditions were variable - at the North Pole we had some thicker ice and some of the planned stops on the way were cancelled due to the ice conditions, which took us also longer to transit than expected. However, at yesterdays ice station, the ice was thinner again, but with a heavy crystallised snow cover on top. The weather was variable - from cloudy to partly sunny and then back to cloudy and foggy. We also had some light snowfall the last days! Let me start with the Ice station B on the day we also reached the North Pole. We were lo...

Cancelled Helicopter flight for Friday 6/8 BUT 36h Ice Station Saturday - Sunday

Image
Friday started as usual - getting up at 5 to launch the morning weather balloon. I was disappointed by the weather conditions I was facing that morning - fog! Not only did the fog prevent us from the helicopter flight, but also the fact that we were a bit behind our schedule and had to reach our first ice station at 86 N by Saturday. Therefore, unfortunately our planned helicopter flight was cancelled and we were mostly steaming the whole day. For many of us, as all CTDs were cancelled too, it ment a more relaxed day: playing cards, doings sports, resting, watch movies, sleeping... For others, it ment intensive planning and preparation for the first ice station. In our project work, we were doing water sampling from the water 8m below the ship, measuring the CO2 concentration in the water. We aim to do several water samples per day during the expedition. It was nice to have one more relaxed day - time to breath and charge yourself - The work on a research ship can be really heavy - som...

Third helicopter station Saturday 21st and begin of fourth ice station D Sunday 22nd

Image
The third ice station (station C) ended on late afternoon on Friday the 20th (with beam net acoustics and helicopter flight, and ice trap retrievals during the day). During the transit to our next stop, we held a lindy hop dance class (Level 2) in the evening and arrived late in the night at the next stop for doing CTDs the whole night and early morning. In the photo below you can see the CTD dragged out of the container to be put in the water (the tubes on the CTD collects water samples from different ocean depths). It is important to take care of the safety when working on deck - yellow helmets and warm bright-coloured dresses to keep warm and visible. The CTD stop was just a short stop, planned to last until Saturday afternoon, whereafter we were supposed to head towards our fourth longer ice station - station D.  In the early morning on Saturday 21st, I woke up again to launch the weather balloon. There were many people awake already at 5am working on their water samples, filte...
