Summer 2016 – Black and Bloom – part 1

it is that time of he year again when me fidgeting is the norm not the exception because the summer Arctic field season is nearing.

This year it is Greenland and it is the 1st field season for a large NERC funded Black and Bloom project that will allow me for the next 4 years to do exciting and fun science with lovely colleagues.  For almost daily updates and links to various twitter feeds see the Black and Bloom website.

Overall and in a simple statement what we aim to do is to:

…..unravel how dark particles (black) and microbial processes (bloom) darken and accelerate the melting of the Greenland Ice Sheet.

 

The projects scientific goals and objectives ore briefly described on our science website  where, following a successful field season. we will also post updates about our results as they come in.

S6 site

This summer there will be 3 teams or maximum 8 people are going  to camp on the Greenland Ice Sheet. We start from in Kangerlussuaq Kanger for short – means Big Fjord) and our field site (red dot on image at left) is located at 67o05’ N, 49o23’W, at an altitude of 1020 m and  ~ 150 m east of University of Utrecht’s S6 meteorological station  (background image from 12/0714 NASA Aqua MODIS).

In total we will spend ~ 6 weeks on the ice and the first 8 member team flies out onto the ice Sikorksy S61 in hangar ready with a Sikorksy S61 helicopter ()

Naturaly team 1 also had to sort out all kinds of logistical issues – like testing the speed of setting up our large tents…

mess tent

… sorting and repacking  our ~ 2.5 tonnes of kit shipped in advance, sorting liquid nitrogen shipments, testing communications, sorting our safety on the ice gear etc etc. etc etc … kept them busy 2.5days but this morning all is ready for take off…

From today onward communication with the Ice-bound team is only via a prearranged, daily satellite phone link to the remaining UK team.

good luck team 1.

Team 2 will join them in 2 weeks and team 3 in 4 weeks. We are all looking forward to a well set up and running camp by that time team 1 😉 – mucho pressure !!

Excitement is mounting!!.

Alex’s Travel Jinx

It all started in December 2014 with a Brazilian-Swedish friend of mine visiting Potsdam, where I had, just 2 months earlier, started a new job at the German Research Centre for Geosciences – GFZ for short. It is thus less than a year since my travel trouble started.

But let me back up a little.

My deal is such that I will build up my new Interface Geochemistry group and labs at the GFZ and thus my new Potsdam/Berlin life progressively over the next 2-3 years. This way I can slowly bring to an end my existing projects in the Cohen Biogeochemistry Labs of the School of Earth and Environment in Leeds, where I still have a vibrant group of PhD students and postdocs who keep me happily busy.

Thus I am basically ‘allowed’ (by choice and love for the challenge) to live two parallel lives, do two (at times it feels like 2 x 100%) jobs and travel even more than usual (which some people though was too much already before).

This slow transition and the invariable yo-yoing between Berlin and Leeds requires me to fly the route Leeds-Amsterdam-Berlin back and forth on average ~ 4 times each month.

So now back to my good Brazilian-Swedish friend Alex (see previous Arctic posts for more info about Alex), who in December 2014 passed on his bad luck and jinxed my usual traveling luck. Alex seem to have the knack to be the most unlucky traveler EVER. If something can go wrong it will. At least that is what he tells me and that is how it felt the last 24 hours!

You are asking why?? Well most normal humans when they travel from Berlin by plane for ~ 24 hours would likely reach Sydney or Hawaii – i.e., travel ~ 10.000 km and get to the other side of the world.
Yesterday I managed to travel the less than 1000 km from Berlin to Leeds in  …wait for it … 24 HOURS !!!

Alex your travel jinx was very strong yesterday!! Really strong!!  Thanks My friend !! Your generosity is really much appreciated!!  
BUT TAKE IT BACK!! I don’t want it anymore.

You likely d not want to know why and what happened but I will tell you anyhow if you manage to read on and not get boooooooooored with my whingeing.

I usually fly with KLM. This is because there is no direct Leeds Berlin flight and in Leeds and Berlin I can get to the airport ~ 40-50 mins before we take off and all is fine and have lounge access so can work. This way I can also make the normally 6 hours door-to-door trip as speedy and comfortable as possible.

Now to yesterday! (it feels like many eons have passed and not 24 h)

My 1st flight was delayed because there was supposedly a storm in Amsterdam so all planes were delayed ! Even the outgoing ones so our connecting flights would most likely wait ! Ok these things happen !

Arrived in Schiphol and my connecting flight had left ! The storm had finished just 30 mins after it started !!!!

The world does not go under and when you travel a lot these things happen. Thus I thought, no problem, been there done that, got a collection of airline overnight kits to show for. The dinner, hotel etc were also no issues and speedily arranged.

However, and this is where the Alex Travel jinx really kicked in ! KLM could not re-book me on the early morning flight BECAUSE ALL OUTGOING FLIGHTS to the UK the next morning were full. It was not possible to get (even with a 1st class upgrade option) a seat in an early morning plane to Leeds, Manchester, London or Newcastle. They even tried Brussels or Frankfurt but than the connecting flights to Leeds were full . And I mean FULL – all flights were overbooked with at least 5-9 people on the waiting lists already !!!

Thus I was not alone – but in that situation I did not care about others to be frank – I just wanted to get home.

The only option they could find was to reroute me via … wait for it … Southampton !!!! YES. I traveled in the morning to Southampton than had to wait 4 h before my Leeds flight and arrive at 2.30 pm.

Not over yet. Naturally they also lost my luggage (and again I was not alone) so another hour in Leeds airport to try to sort that and thus arrived home exactly 24 hours after leaving with no luggage, rather pissed off, and tired.

Thus I can only say – Alex – Thanks, but you can have your Travel Jinks back !!

Spring and Summer 2015 – Svalbard here we come again

it is July and thus that time of the year again when I get antsy about leaving civilization behind and having some fun up North. It is summer and while this week I am still sitting in my new GFZ office I suffer from ‘what summer actually means’ – i.e., heat and sun. It is ‘nice’ but after living in the UK for more than 15 years it takes some getting used to ‘proper hot summers’.

But alas soon (counting the days) it will not matter as I will take off for my annual pilgrimage to the ‘top’ part of the world. I am off to Svalbard again for my yearly fun-work-trip to a colder region of the word but for me the blissful region.

Although this year I already spent a week in Longyearbyen (capital of Svalbard, Norway) in March when it was still all snowy I still need to go back to get my Arctic fill. In March  Steffi and I took a fabulous snow scooter trip from Longyearbyen to Tellbreen and sampled ~ 100 kg of fresh snow to analyze for all kinds of stuff…

After melting all that snow at UNIS (and without mentioning the various puddles) we filtered it all through various filters and we got …. well not much (that is science for you). newerthelss, despite the few data we obtained or not, we learned a lot about what and how to do it better next time; the optical measurements worked, the biological and organic ones less so but there is always a next time.

Anyhow – now it is summer, much of the snow is gone in the lowlands and Svalbard is calling me again.

This summer mynSvalbard stay will only be for 2 short weeks that will be in two parts.

In week one we will be camping in Ebbadalen (Billefjorden) and our aim is to sample rocks along a sedimentary transect to study …. (see later)

This part of the trip will in part be a trip down memory lane with friends from Norway and the USA. We have visited this site already ~  10 years ago.

This year several ‘old’ friends (naturally NOT in age but due to the status of common ‘Arctic ‘war’ buddies) agreed to assemble again in Longyearbyen and take a trip down memory lane while going back to Eddadalen. We want to try to elucidate the problems related to the abiogenic or biogenic nature of ‘blueberries’ (see later blog) in the evaporite sequences in Eddadalen.

The team will consist of : the sedimentologist, Arctic all rounder and our safety guru Ivar (University of Oslo, Norway), the chaotic lovely Steelie (Carnegie Institution of Washington),  queen Thora AKA Marilyn and Chris (University of California Merced) as well as another BOS (Babe Of Science)  Pan (NASA Goddard Space Flight Centre). We will be joined by two new members (Anja Sundal arom Oslo Uni and Steffi Lutz from Leeds Uni) who will make sure we stay on track and do not divert too much into the past 🙂 . This is because our common aim is to have as much fun as possible, not be eaten by Polar Bears and do some great science.

In the second week Steffi and I will fly to Ny Alesund, where we will be stationed in the Sverdrup Station as guests of the Norks Polar Institute. Our aim is to collect rock samples from the forefield of Midre Lovebreen to complement samples and data for our Arctic Soils project and also to sample again snow and ice on the top end of Feiringbreen as part of Steffi’s PhD project (well these samples will be part of life beyond her PhD 😉 ).

Summer 2014 Guestblog by Joshua Blacker (@6josh) – Arctic feldwork – Tarfala -“The End is Nigh” :-(

Week two: “The End is Nigh” 😦

We started the 2nd week with great enthusiasm after the first week’s sampling success and with the continuation of the marvelous un-Arctic-like-weather, ~20°C sunshine.

By Wednesday evening we completed the sampling of the whole sequence in front of Storglaciaren. We established a nice sequence and with many samples collected biologically clean and in triplicate and with all the in situ measurements done at each site we were happy to have a great set of samples. In addition, we also managed to collect at two different sites two full 50 cm cores very successfully … these will be used to gain a depth profile of the sites with respect to changes in weathering and biological succession and thus complement the chronosequence data.

And that was not all; together with other researchers at Tarfala we had the chance to fly again in a helicopter and managed to sample another (also well dated by images and through clear moraines) chronosequence in the forefield of different glacier – Rabots (67°55’N, 18°29’E). The forefield of Rabots allowed us to sample an alternative sub-Arctic site and this will act as a perfect comparison to Storglaciaren and the glaciers sampled last year in Svalbard and the ice sheet forefield sequences that I will sample in a few weeks in Greenland. Rabots is very different topographically to Storglaciaren because amongst other major differences, the forefield of Storglaciaren is a lot steeper to both Rabots and Midre Lovebreen (Svalbard).

Rabots glacier is also well known because of a catastrophic military aeroplane crash in March 2012, which resulted in human fatalities and its wreckage including a large amount of hydrocarbon fuel was scattered on the surface of Rabots glacier and dispersed in its catchment. Glaciologists from the University of Stockholm who work at Tarfala Station continue to study the effects the hydrocarbons have  on the glacier and local ecosystem.

It is important to note that Tarfala has a great lab facility and thus when we returned our samples back to station eahc day we could immediately also process the samples. For the soil samples we measured pH and conductivity, we also measured bulk moisture contents and wet and dry soil colour …

…. and fantastic weather (which even melted within short time Olaf the snow man that was build by Katja and Pia – station staff)…

… sadly it was time to leave. We packed our equipment, removed our samples from the -80°C freezer, weighed and distributed the samples in the various ice boxes and again via helicopter we left Tarfala with some fantastic memories and the will to return at some point.

 

The glaciers of Tarfala Valley

Summer 2014 Guestblog by Joshua Blacker (@6Josh) – Swimming in an Arctic lake – for fun!

Week 1 – – Swimming in an Arctic lake – for fun!

We arrive at Tarfala station after an enthralling Helicopter shuttle ride. On the approach we could see the research station nestled at the lowest part of a-typical glacial U-shaped valley. The landscape at first glance was an amalgamation of an Alpine/Arctic environment and thus we immediately saw that this would provide us with a unique place to study the initial stages Arctic soil formation.

The stations chef greeted us upon landing. He was a young chap with a Viking-like appearance bearing pagan medallions around his neck, a short scruffy beard and long hair. We unpacked our belongings and research equipment then conducted a field-recce of the Storglaciaren  forefield – this will be our primary field site.

The forefield of Storglaciaren (67°54′10″N 18°34′00″E) was chosen as a field-site as the glacier holds the longest recorded continued monitoring of its mass balance in the world – they monitored this in detail since 1946. Using a combination of satellite imagery, aerial photograph and old maps we were able to date a succession of moraines left behind by the retreating glacier since the Last Glacial Maximum. This chronosequence (age-sequence) aids us to investigate how sub-Arctic soils form.

Over the course of the next two weeks we planned to collect a clear sequence of samples from the terminus of the glacier where newly exposed rock/sediment/minerals were visible and all the way to highly vegetated ‘mature’ soils. Furthermore, we also collected samples from the glacial surface (snow algae, cryoconite and other microbial samples) as well as outflow samples from the draining rivers to obtain an idea of what inputs chemically drive Sub-Arctic glacial forefield development.

At the end of day four/five we had collected approximately 2/3rds of the samples from our glacial forefield. To celebrate as a representative of the British team I decided to swim one of the many pro-glacial lakes that were fed by glacial melt water (and this promptly impressed the Swedish leader Ninis !) .

As you can imagine the water was freezing, literally (1-2°C). Small snow lumps floated past as I attempted to maintain my cool and swim; a few days later even the ‘elders in the Bristish team (liane and Alex) took a swim – and even Alex – our local Brazilian was therefore forgiven for yelping like a wounded animal because he was not accustom to the cold water.

At the weekend we decided to take leisurely hike, but being scientists we couldn’t resist to combine this with more sample collection collecting – this time a little more icy – snow algae for Steffi (see previous blogs). We hiked up to Darfaljavri, a glacial lake and then 1/3rd the way-up Kaskasatjåkka mountain (2072m) to observe the spectacular views of Tarfala Valley and of the four glaciers situated within it.

Although we came across plenty of green snow along (a precursor to the red snow) the red Chlamydomonas nivalis (red/watermelon snow algae) eluded us, as it was too early in the melt-season. Interesting fact: red snow algae produce carotenoid pigments (the same you find in carrots) to protect them from powerful solar radiance found on fresh snow that has a high albedo – their own form of sun cream… cool!

Sunday was our intended day of ‘tale it easier’, yet upon hearing that some of the station’s staff were going to find an ice cave I couldn’t resist. The trek to the cave was a fairly routine hike. As we climbed higher out of the valley it’s sides became steeper and more treacherous, we edged along its periphery using our crampons and ice axes until we spied the opening.

Marvelous experience. More to come.

Part 1 – Arctic Sweden – The bugs ‘rock’ in Tarfala

————

Day 1 – “the joys of traveling”

So it begins, our journey into the land of the “swedes”. We arrive promptly at Manchester Airport at 6 am, equip with five over-cumbering pieces of luggage, a bazooka (1.5m depth probe) and toes that were itching to walk-upon Arctic soil and ice once again.

@ Joshua Blacker

The first stop on our journey was Switzerland, Zurich, and after a brief moment deliberating whether we should stay or vacate the airport, we head for Zrich city centre. Liane, being well acquainted with Zurich (studied there for her PhD) took the role of tour guide for the afternoon. Zurich was beautiful, partially because the Swiss clearly took so much pride in everything (it was not surprisingly extremely spotless), but also because the city is situated in a valley surrounded by rolling mountains with a large lake in the bottom… and because of chocolate… and sunny weather

Our next flight Zurich to Arlanda, Stockholm was delayed and the next transfer was a nightmare – we arrived in Stockholm to find our luggage re-check-in was 1000000 miles away from where we picked it up from the conveyor belt – it was in a different terminal at the other side of the airport. We dashed through Arlanda airport and its many obstacles with our strange luggage… and the bazooka to find our next flight was also delayed… phew! We thought we will miss our flight but as it was also delayed we managed to actually meet our third party member – Alex Anesio A.K.A the pooper trooper, from Bristol.

Finally after 16 hours of traveling (almost enough time to reach the west coast of the U.S.A) we arrived in Kiruna in Arctic Sweden (68° N) – our final destination – to a specular rainbow.

Summer 2013 – Part 3: The hunt for Arctic bugs – Arctic Sweden: Tarfala

It is beginning of July and after two NERC proposals submitted in time and a paper correction round done I am back on the road.

Field trip no. 2 of my Arctic summer took me to Sweden. Here we aim to chase down again snow and ice algae and understand how and why they not just survive in cold settings, but indeed why and how can they thrive.

After taking a taxi, 2 planes, another taxi and than a helicopter Steffi, Ben and myself arrive in the afternoon of July 1st to the Tarfala Research Station in Arctic Sweden. This is close to the mining town of Kiruna, which is above the Arctic circle – a first for Steffi and Ben so they are excited. Arriving in Nikkaloukta – one hour from Kiruna and the last stop before Tarfala, we had 2 surprises. First, we arrived in the Arctic and the temperature was way too high, it seemed all very wrong to have 19˚C – which is far warmer compared to Leeds.

IMG_0834

Secondly, waiting for about 1 hour for our helicopter we were eaten alive by millions of mosquitos. Our shipment with 4 boxes as well as all our other gear finally in the helicopter and 10 minutes flight and we saw the station and the glacier. Not even out of the glacier and we are happy as we immediately saw a lot of very red snow fields from the air so were sure that on ground it is no problem whatsoever.

IMG_0928 cropIMG_0928_cropped smallTarfala station is located at 1130 meters above sea level and is close to Storglaciären the glacier that has the longest mass balance monitoring history in the world (started in 1946). This glacier is one of many in the area and is close to the highest mountain in Sweden, the Kebnekaise (2106m).

This fieldwork is supported by an INTERACT grant. INTERACT is an EU funded International Network of Arctic Research Stations which support various studies related to changes in the terrestrial environment. Last year we spent – again supported by INTERACT – 2 blissful weeks in SE Greenland – at the Danish Sermilik Station, studying the glacial ecology of Mittivakkat glacier.

This year we wanted to expand this work also to Arctic Sweden and thus we are at Tarfala where from the far distance you can see  red snow everywhere on the snow fields and glaciers. Thus we were happy.

Before we arrived we closely monitored the weather and it was supposed to turn bad the next day. Thus together with Ninis (Gunhild Rosqvist – a professor at the University of Stockholm and the Tarfala Station Director) we walked up to Storglaciären and immediately started our sampling. We also meet Torbjorn Karlin – the Station Superintendent and Glacial safety expert at the station.

IMG_0890Within ~ 2 hours we sampled 6 snow (red and green and biofilms) and ice sites and were ready to walk down to the station. On this glacier in contrast to Iceland the red and green snow areas were so obvious that it was a very easy sampling trip.

IMG_0880

The nice thing about the Tarfala Station – besides its proximity to various glaciers and thus perfect for our work – is the fact that when one returns to the station in the evening dinner already awaits and the fact that after dinner one can take a nice shower and enjoy the sauna (yes sauna – Arctic, hot, bliss). Thus, the evening could only go well. We also meet all the other people at the station which includes people of all levels from Stockholm University (from undergraduate students to the head of department) but also from other universities as well as 4 college students who were at Tarfala for a few days of Arctic field experience. What a place to learn about science and the environment.  We should strive to arrange more of these also in the UK, as it is invaluable experience.

IMG_0921IMG_0893image001

The station was also well equipped for doing our science. Indeed, using the nice, new Leica microscope that the station purchased this year (Ben helped install it) we got immediately some great images of our red snow algae cells. This confirmed our field studies with our new field microscope that we tested and that worked. In Iceland we wished for microscopes to identify and see our cells in the filed. Thus, this time we came with one and this way it was easier to decide if the field sample is good and what other things are present in each sample.

We were also fortunate that Ninis and her team had scheduled the next day a trip over to Rabots glacier –  the glacier where on the 15th of March last year, in-2012 – a military plane with 5 people crashed into the mountain side. Despite some clean up efforts for all the bits of plane etc., the kerosene spill was still creating a problem with pollution and Ninis asked us if we could also have a look at the microbiology of the contaminated site.

She had collected a sample for us that she said was from the ‘clean’ snow area. Alas looking at it under the microscope what we found were still clear signs of contamination. Next day when we visited you could also easily still smell the organic light volatiles compounds when on the glacier. We also took new samples from really far away from the crash site for comparisons and sampled the whole glacier for red and green snow as well as and dark brown to black biofilm like materials that form at the snow ice interface. What a marvelous field day.

Anyhow, the next 10 days we collected many more wonderful samples and all in all we have spend a lovely time at Tarfala. Despite the strong winds we have achieved what we came for and most likely will be back next year for more work.

Thanks to all the gang at Tarfala who under the guidance of Ninis made our stay really memorable.
