Left Longyearbyen in the early morning, 14 hours of navigation through sea-ice by boat were necessary to land in Ny-Ålesund, a small town on the west side of Svalbard that brings together several research institutes from different countries. After some hours spent in courses about rules, safety, and all the precautions against the wildlife present outside of the town, the organization of field and laboratory activities finally began.

The purpose of this scientific campaign is to study the thawing of permafrost, looking for active microbial communities involved in organic matter degradation and greenhouse gas release. So day by day, our research group is divided into two main teams, the "Drilling Team", and the "Lab Team". The "Drilling Team" has to look for spots with ideal geological features and get there by snowmobile. Before starting to drill, reaching the frozen ground is necessary, sometimes shovelling half a meter of snow.

Then, the drill can be placed and activated, trying to get more permafrost cores from as deep as possible. Moreover, to allow safe working conditions, one or two people have to stand on guard against polar bears.

The obtained permafrost cores are then transferred to the laboratory where the "Lab Team" section the frozen cores into smaller parts, and then subsamples are taken to be stored and then analyzed in the next months following a multidisciplinary approach.

Days go fast and we hope to get as many samples as possible!

As we got off our boat ‘Farm’ that took us safely and steadily to Ny-Ålesund from Longyearbyen, I looked up and tried to digest the fact that after so much hustle and bustle we were finally standing at 79°North! With all the snow-clad mountains and pretty pink sunsets, I was surely already in love with this place.

Cut to day 3, when the wind was howling at a speed of 35 m/sec blowing piles of snow into our faces. We were pacing ourselves to set up our lab. As you can tell, today wasn’t the most pleasant day in Ny-Ålesund. There was a snow blizzard outside, and I was dragging my tiny body squished inside my bulky snowsuit to the laboratory. While barely walking to the lab (mostly being carried by the wind), I thought to myself, “How do people do this? What kind of a willpower does one really have to travel to the most extreme places on earth?

How have I even dreamt of walking on Mars one day if I’m struggling just here?” And with all those thoughts flowing faster than the wind around me, I reached the lab.

We started unboxing the lab instruments, pipette tip boxes, DNA extraction kits and all the other magical scientific equipment to get ready for the big field day. I was looking around and I could see us newly started, fresh graduate students excitedly set up our desks, I could see people discussing experiments and testing instruments, I could hear small cheers here and there with yayys and woopwoops when my friends could find something they were scavenging for in the giant science boxes. And there it was, I had found the secret sauce that drags researchers from different parts of the world to visit such extreme places on our planet. It is the science! I looked at myself in a shiny glass of the laminar flow hood, and I could totally justify that smile I had, “It’s the things we do for science.” I whispered to myself.

When I walked back to my room, I sat down and paused for a moment. I could still hear the wind gushing, but this time it was out of my window. I gathered all the things I had felt throughout today, and if I had one word to describe those feelings ‘gratefulness’ would top the list. To be working with such great scientists, discussing adulting with the coolest fellow grad students and doing science at one of the most beautiful yet brutal places on our planet is an out of the world experience. And I am eagerly looking forward to the big field day and whatever that comes out of it!

As a Svalbard “first-timer”, I am awed by the crisp air, bright fresh show, and mountains that seem to rise out the ocean on Svalbard. It is a beautiful place. Our stay in Longyearbyen was a nice transition into the field. There are two ways to get to our research base in Ny-Ålesund – a 15 minute flight or a 12 to 16 hour boat ride. Our team opted for the boat ride.

At 4 am we boarded the MS Farm captained by Stig Henningsen to travel from Longyearbyen to Ny-Ålesund. Our route took us through the sound of Forlandsundet separating Prins Karls Forland and the west side of Spitsbergen. The views from the boat were amazing! Even though the wind was biting cold as we stood on deck to enjoy the view, we were warmed by the sun in a clear blue sky. Our boat broke through shallow sea ice as we travelled northward. We travelled through pancake ice, a type of sea ice that looks like pancakes floating on the surface of the water – this is a phenomenon I did not know existed until now!

After around 16 hours on the boat we arrived in Ny-Ålesund, the research town that will host us during the rest of our stay in Svalbard. Ny-Ålesund hosts permanent research institutes from several different countries. We are being hosted by the Norwegian Polar Institute. Our research site is ~3 km northwest of the town and there we plan to drill permafrost samples for microbiological analyses. Wish us luck!

After 10 days spent in a "quarantine" hotel in Oslo and a bunch of Covid Test, we are finally at Longyearbyen, Svalbard, the last step before the beginning of our field activities. After we landed, it took me just a few minutes to understand where I am and think "WHAT AN AMAZING PLACE!!!!". High white picks, a beautiful fjord, and multiple lines of coloured houses that follow the side of the hill. A week ago, the sun has come back after four months of darkness. The town is completely covered by snow, and the temperature is around -20°C, perceived as -30°C. The air is so cold that less than an hour spent outside is enough to make the eyelashes and the beard completely frozen. However, low temperature and flowing wind didn't put our spirit down, so, yesterday we moved to visit a glacier called Larsbreen to enjoy the incredible landscape visible from there, and it was gorgeous.

Anyway, our time in Longyearbyen is about to end. Tomorrow in the early morning, we'll head to Ny-Ålesund to start our work. I am grateful to have experienced some days here in Longyearbyen, and I hope it is just a goodbye.

AMP’D blog #2: Meet the team!

3/12/2021

The AMP’D field team comprises microbiologists, biogeochemists, geophysicists and modellers, with expertise in a wide range of environments from glaciers and permafrost to the deep subsurface, coral reefs, and hot springs! Excitingly, this will be the first time that many of us will be working in the field together (and even the first time meeting each other for some!).

The AMP’D field team is:

Karen Lloyd, AMP’D Lead PI
Karen is an Associate Professor at the University of Tennessee, Knoxville USA. She studies deep subsurface microbes “in the wild” and tries to determine what they’re doing out there that’s helpful for Earth processes. Coming from an oceanography background, this is only her second project in permafrost, so she is excited to see whether microbes have similar strategies for surviving in oceanic vs. terrestrial energy-starved environments.

Tatiana Vishnivetskaya, AMP’D Co-PI.
Tatiana is a Research Assistant Professor in the Center for Environmental Biotechnology at the University of Tennessee, Knoxville USA. She is fascinated in uncovering microbial biodiversity in deep subsurface permafrost, and other extreme environments. Her interests lay in understanding how microbial community changes during environmental change. She also wants to know what makes the microbial genus ubiquitous enabling it to occupy different habitats. In her research, she applies a variety of classical microbiological and next-generation high-throughput techniques. In collaboration with Russian colleagues (IPBPSS, Andrey Abramov) she created YouTube videos to extend public knowledge on Siberian permafrost area and research ongoing there.

Brianna Green
Brianna is a Master's student at University of Tennessee Knoxville, working under Dr. Andrew Steen. Her research experience throughout undergrad would be described as interdisciplinary. From assessing Uranium concentration in water in soils, analyzing oceanographic data, and culturing Cave and Hot Spring Sulfur-bacteria, she has built a research interest in biogeochemistry. Having done fieldwork in hot springs, on a hot summer day in August, she knows Svalbard will be MUCH different. This will be her first time in Svalbard and first time going outside of the United States. While daunting, she is looking forward to the adventure as well as the opportunity to meet others in the scientific community and gain more field work experience!

Katie Sipes
Katie is a PhD student with Karen Lloyd at the University of Tennessee, Knoxville USA in the Microbiology department. This will be Katie’s 3rd trip to Ny-Ålesund and the second trip to drill permafrost. In 2018, Katie planned a trip to drill active layer permafrost in Ny Alesund along side another group’s fieldwork. After securing equipment and guidance from a variety of locations and agencies (NSF, U.S Ice Drilling Program, Jon’s Machine Shop, Jonathan Holmgren, Forest Banks, Geoff Miller) Katie executed the drilling plan near the Bayelva permafrost monitoring site. Katie has been studying the permafrost metagenomes, geochemistry and soil enzymes in the Svalbard permafrost for her dissertation. Katie is looking to defend her work within a year and will be ready for the next step. She hopes to continue studying metagenomics in permafrost/extreme environments in the future.

Margaret Cramm
Margaret is a PhD student at Queen Mary University of London. She is interested in “misplaced” microorganisms – those found in environments not suitable for their growth – and how these organisms respond to their environment as it changes. She is particularly interested in using dormant organisms to explore life’s history. She has conducted fieldwork in the Canadian Arctic. Her visit to Ny-Ålesund will be a new high latitude record for herself.

Andrey Abramov
Andrey is head of the Soil Cryology department at the Institute of Physicochemical and Biological Problems in Soil Science (IPCBPSS RAS) at the Russian Academy of Sciences. His main field of expertise is aseptic drilling, thermal state of permafrost, searching for the oldest and coldest frozen ground on Earth. He dreams about drilling on Mars one day. His field experience covers the Arctic (Russia and Alaska), Antarctica (6 campaigns, including 2 circumnavigations and one to Dry Valleys) and high mountain areas, preferably of volcanic origin (Kamchatka and Caucasus). His main driving force is gravitation - he likes to include some freeriding or paragliding to the expeditions.

AMP’D blog #1: Arctic Microbial Permafrost Degradation

3/10/2021

James Bradley

Permafrost at high latitudes contains around one third of the world’s soil organic carbon. This frozen carbon is increasingly vulnerable to thaw and microbial degradation as climate change intensifies, potentially leading to large-scale release of carbon dioxide and methane to the atmosphere. Understanding this threat is the motivation behind our project ‘AMP’D: Arctic Microbial Permafrost Degradation’, primarily funded by the US Department of Energy, with additional support from the British Antarctic Survey. The Norwegian Polar Institute will be providing logistical and operational support in the field.

Our team is travelling to Ny-Ålesund, Svalbard, which at 79°N is only a few hundred miles from the North Pole. Once there, we will drill into the frozen Arctic ground to understand how climate change is changing soil biology and chemistry, and driving carbon dioxide and methane release from the soil.

One year later than originally planned (due to the Covid-19 shut-down cancelling our field work last year a few weeks before we were scheduled to go), during which a further 36 billion tonnes of CO2 have been released by humans to the atmosphere, our team of eleven scientists have made it from five different countries to Oslo, Norway, where we are confined to hotel quarantine before it is safe to continue on to Svalbard.

Our extremely complex Covid-compliant logistical plan has encountered numerous difficulties along the way, and is still under constant review, as we lose count of the number of flights we’ve changed. Yet we remain in remarkably high spirits.

In a matter of days, Covid-tests permitting, our whole team will be arriving in Longyearbyen - Svalbard’s largest settlement of just upwards of 2,000 people, to embark on a ship that will sail us further up the western coast of Spitsbergen to our field site.

Check back in and follow our adventure over the coming days and weeks!
