The Midnight Sun and Fermented Fish

We returned from Abisko on Thursday July 9th around 10 p.m.  The next morning was very busy for the crew as we had to put the science gear back together, prepare the boat, and do local newspaper and radio interviews.

Here are the links to those interviews: radio | paper

Like the transect north, our southern route is based on collecting samples at sites for which our Swedish collaborators have secured permits. Before turning south towards Stockholm, we had to sail north 40 miles to collect two samples in the northernmost part of the Bothnian Bay. Over the next five days we sailed down the east cost of Sweden, and during that time we collected nine samples from five different HELCOM sites.

The most interesting stop on the sail back to Stockholm was the Island of Ulvön, a tourist destination known as the “Pearl of the Sea of Bothnia.”  We only spent 15 hours on the island, but the experience will be cherished by the entire crew thanks to the Northern Swedish dish called Surströmming, which is fermented herring. A friend of mine with family on the island set up a tour of Erik Den Röde, a high-end brand of Surströmming owned and operated by Ruben Madsen (link 1 and link 2). Ruben is a very interesting person, and with a background in the Russian circus and a love of fermented fish, he put on an impressive show that we will never forget. From my first days in Sweden I was warned of this dish and was informed to never open a can on the boat due to the horrible odor that you will not escape. As Ruben opened the can the crew looked worried, but to our surprise the smell was not overpowering. We all tried a piece in the traditional way (on a piece of flat bread, with chopped red onions and cream). I went first and decided the piece of fish was too small, so Ruben made me taste with a huge chunk of the fermented fish. I required a big sip of Swedish beer to finally swallow this delicacy…

The next morning, with fermented fish still in our stomachs, we departed for our two day sail back into Stockholm.

ROAD TRIP! Watch Out Arctic Circle…the Sorcerer II Sampling Team is Coming Your Way!

After we arrived in Luleå, Jeremy, Karolina and I started packing for our road sampling trip to Lake Torneträsk, a freshwater lake located in the Arctic Circle.  Dr. Erling Norrby had contacted Dr. Christer Jonasson, the deputy director of the Abisko Scientific Research Station, to help coordinate our sampling trip.  The research station is located in Abisko, Sweden approximately 130 miles north of the Arctic Circle and is 1,300 feet above sea level on the south shore of Lake Torneträsk.

On the morning of Monday July 6th, with the rental car filled to maximum capacity including three carboys strapped to the roof, we set off for the 270 mile road trip to Abisko.  During the six hour drive we discussed our excitement about seeing such a unique environment and having some time away from the boat!  No offense to the others onboard but sometimes 95 feet can get a bit small. While driving we enjoyed the view of the snow capped mountains, thick green forests and the signs that warned us of moose crossings.  That is correct, we were in moose country and we were on high moose alert…sad to say there were no moose sightings.

After arriving at the station we were met by Dr. Jonasson who showed us the facilities and our apartment.  The apartment was very nice and had a fully equipped kitchen; we were all looking forward to cooking for ourselves.  The first night we settled into the apartment, cooked dinner and enjoyed our view from the living room overlooking the lake and the mountains in the background.  Since we were so far north in the Arctic Circle we experienced the midnight sun. It was an amazing experience, although it did interrupt our sleep cycles!

The next day was spent setting up the lab and collecting our samples from Lake Torneträsk.  We drove down to the lakeshore and filled 200 liters of lake water from a pier that stretched out 20 meters into the lake.  Lake Torneträsk doesn’t thaw until June so the water we collected by hand was 7°Celsius (44°Fahenheit).  Needless to say it was not the most enjoyable experience.  The water was crystal clear so we thought we would have to sample 500-1,000 liters to get enough biomass for DNA sequencing.  After only 200 liters, all 3 size filters were completely full of microorganisms and had distinct colors.  These filters had more life on them then what we see in open ocean samples when 400 liters is filtered.  The sample collected from Lake Torneträsk is a very unique sample because the lake is a major freshwater contributor to the Baltic Sea.  The data will be very interesting to compare to the other samples collected on our North/South transect of the Gulf of Bothian.

We took full advantage of the long sunny nights by doing hikes up the surrounding mountains and rivers that feed the lake.  The time spent at the station was important scientifically and for crew moral.  It is always reinvigorating to get off the boat, get some exercise and experience these unique environments up close.

The last leg of the Volvo Ocean Race, the Swedish Archipelago and the Gulf of Bothnia Sampling Transect

The morning of June 25th we left Stockholm and followed the Volvo race boats into the Baltic to watch the start of the last leg of the race to St. Petersburg. Once again there were hundreds of boats on the water to watch the start of the race.  As the race began we saw someone waving to Dr. Venter and Dr. Norrby from another boat.  It turned out to be King Carl XVI Gustaf! (Note: our friends on PUMA achieved second place in the final standing of the race.  Congratulations!)

After we watched the boats sail into the Baltic, we started making our way through the Swedish Archipelago.  These waters are very difficult to navigate so it was a relief to have Dr. Norrby onboard to help Captain Charlie and Dr. Venter maneuver in these rocky, shallow waters.  Dr. Norrby has years of experience sailing in the Archipelago as well as extensive knowledge of the Swedish coastlines.  During the last two days, Dr. Venter, Dr. Norrby, Captain Charlie, and the Sorcerer II crew had many meetings to plan and plot our course for the north/south sampling transect of the Gulf of Bothnia.  This is going to be one of the most intense sampling legs on Sorcerer II to date, but we all agree that the samples collected on this transect will be some of the most unique we have seen.

With a busy two weeks of sampling coming and Dr. Venter and others returning to the States, we decided to celebrate the 4th of  July on June 29th.  With Sorcerer II docked in front of Dr. Norrby’s summer house, we celebrated with a special dinner and launched a few expired flares for some fireworks to mark the occasion.

In the News

We docked in the Volvo Ocean Race Village for a week. It was very exciting to be so close to all of the activities surrounding the race. Over the week Dr. Venter and Karolina and I were interviewed by many local and national TV, radio stations and newspapers. Here are some links to a few of the news stories: Story on Xconomy; Story on TV4play.se.

Dr. Venter was also part of a half-day symposium moderated by his good friend Dr. Norrby and attended by the King of Sweden. After the lectures were over the King of Sweden boarded Sorcerer II to tour the vessel and get an in-depth look at our sampling procedures and to better understand the science we do.

The week in Stockholm went by quickly as it was filled with lots of activities from the press interviews to tours for some of the Volvo sailing crews and some men from the Swedish Navy, to celebrating Midsummer with traditional Swedish food and fun. It was very exciting for all of us, and the positive public exposure the expedition received is great for the ongoing scientific research being performed on Sorcerer II.

The Volvo Ocean Race

We arrived in Sandhamn at 10 p.m. on June 15th.  It was perfect timing because the Volvo Ocean Race boats were arriving around 11 p.m. The Volvo Ocean Race, formally known as the Whitbread “Around the World Race,” began in Alicante on October 11th 2008 and ends in St. Petersburg on June 25th 2009. Sorcerer II was docked in a perfect location to watch the boats come into the finish line.  I was not very familiar with the Volvo Ocean Race, but now I know these people are true sailors and adventure seekers (I might also add a bit crazy as you sort of have to be in order to do such a race!).

On June 17th  Dr. Venter and Dr. Norrby were offered the opportunity to sail on the PUMA boat named Il Mostro and skippered by Ken Read for the Sandhamn to Stockholm race.  Sorcerer II along with hundreds of other boats watched the start of the race and then for the next three hours followed the boats into Stockholm.

It was really exciting to motor sail into Stockholm in the midst of all the celebration around the race. Karolina was also really excited to be back in her home city and have the opportunity to show off her city (more on that later). The crew docked the boat at the Volvo Race Village, and we attended a special reception for the race boats at the Royal Place of Stockholm.  The King of Sweden, Carl XVI Gustaf spoke and welcomed the teams to Stockholm, and afterwards Dr. Venter, Dr. Norrby and members of the crew met with the King and crew members from the race boats.  The reception was followed by a delicious dinner organized by Dr. Norrby at an inn that dates from the 1700’s.  Today also happened to be my birthday, and it will be remembered for many reasons!

Sampling in Helgoland — A warm German welcome for the Sorcerer II

After a little more than two weeks in Plymouth, UK the Sorcerer II set sail on June 3rd. We were sad to say goodbye to our new friends at PLM, but we were grateful for their hospitality, friendship and scientific collaboration. We’re looking forward to coming back through Plymouth in the fall.

We motor sailed in calm weather but with all the other boat traffic in the English Channel we were on constant watch. On June 6th we arrived on Helgoland, an island about 70 kilometers from the mainland. While Germany has many islands on its coast this is the only high seas island and it is a beautiful land with red sandstone rock. Scientists from the Alfred-Wegener-Institute for Polar and Marine Research, the Biologische Anstalt Helgoland, the Jacobs University Bremen and the Max Planck Institute for Marine Biology joined the Sorcerer II crew to sample another long term research site called the Helgoland Roads Long Term Ecological Research Site  or ‘Kabeltonne.’ The sampling site Kabeltonne is located just outside the main harbor of Helgoland located in the southeastern corner of the North Sea.

Dr. Frank Oliver Glöckner, Head of the Microbial Genomics Group at Max Planck Institute for Marine Microbiology was quoted in a press release regarding the collaboration with the Sorcerer II crew, “Sequence data from the Sorcerer II will complement and improve our own MIMAS data. I asked Frank to contribute to our blog so what follows below is his and his team’s account of their experience to have the Sorcerer II come to Helgoland.

Sunday afternoon the Sorcerer II crew toured the Alfred-Wegener-Institute for Polar and Marine Research facilities and aquarium.  The tour was led by Dr.  Karen Wiltshire, director of Biologische Anstalt Helgoland & Wadden Sea Station Sylt, and was followed by a tasty BBQ hosted by researchers Sonja Oberbeckmann and Katherina Schoo.  It was a wonderful day and our hosts in Helgoland were superb. A heartfelt “thank you” from the entire Sorcerer II crew.

From our collaborators in Germany:

Helgoland Ahoy.  The Sorcerer II has reached the first German harbor.

Already some weeks ago rumors came up that the Sorcerer II might have a sampling stopover in Helgoland, a rocky island in the middle of the North Sea. E-mails were flying back and forth to get the permits and organize the stay. June 2nd we got the message that the crew has left Plymouth and is now heading for Helgoland. We were excited – the Sorcerer II will really come to Helgoland and even stay two nights in the harbor! Those not living on Helgoland quickly organized their travel.

From the other side of the island you could see the large mast of the Sorcerer II. We could not wait to get in contact with the crew and what a warm welcome! Like a swarm of grasshoppers we entered the ship for a visit. All of us wanted to have a look how this beautiful yacht looks from inside. How do the sampling devices look like? How do you store and ship the filters? Many questions arose and got answered patiently by the crew. Action came up when we were allowed to join the sampling of the Helgoland Roads Long Term Ecological Research Site named ‘Kabeltonne’. In former times a buoy was anchored at this site to hold a cable connecting the main island with the Dune, a sandy smaller island populated mainly by seals and tourists in the summer months. The ‘Kabeltonne’ itself has been removed many years ago and is now standing as a reminder of former times in front of the Biological Station Helgoland (BAH) as part of the Alfred-Wegener-Institute for Polar and Marine Research (AWI). Nevertheless, since nearly 50 years samples are taken at this station to monitor food web interactions and the influence of climate change and the diversity of microbial communities in the North Sea.

Sampling with the Sorcerer II at the station ‘Kabeltonne’ goes quickly, the real work with all the filtrations and finally sequencing and data analysis comes later explains Jeff, the lead scientist on board. The sequence data from the Sorcerer II will complement and improve our data of the recently started MIMAS (Microbial Interactions in MArine Systems) project. The MIMAS project generates and integrates diversity, metagenomic, metatranscriptomic and metaproteomic data with contextual data like temperature and nutrient concentrations. It’s exciting – with the Sorcerer II data we are now able to compare the North Sea with marine habitats on a global scale. The day finishes with a barbecue at the BAH including traditional Helgoland food and some duty-free drinks. At the end it’s like we say good bye to good friends. The Sorcerer II has to leave for the Baltic and finally to pick up J. Craig Venter in Stockholm. Nevertheless, we hope that we do not need magic to convince the crew to have another stopover on their way back in August when they finally go to the Mediterranean for the winter.

We all wish you a good trip and happy sampling:

The Final Plymouth Sample

I returned to Plymouth on Sunday, May 24th after attending a wedding in Venice. During my time away I missed a tour of the Plymouth Marine Laboratory (PML) and the Marine Biological Association. Fortunately, Dr. Jack Gilbert arranged a second round of tours for Sorcerer II crew members who had not been able to attend. Like Karolina I was very impressed with both institutions. (For more details on the tours, please refer to Karolina’s blog of May 20th). I also apparently missed many good times that the crew of Sorcerer II shared with the PML team including a great dinner with staff from the University of Exeter, and the University of Plymouth Medical School.

On Thursday, May 28th the Sorcerer II crew, accompanied by Dr. Jack Gilbert and two of his Ph.D. students, headed out for one final sampling trip. The destination was E-1, a long term research station for PML located about 25 miles off the coast of Plymouth in the English Channel. As we arrived on site PML’s research vessel Plymouth Quest was there collecting ancillary samples to be paired with our metagenomics data. Below is the CTD cast from station E-1. Based on the information collected from the CTD cast, the Sorcerer II crew, Dr. Gilbert and the scientific team on the Plymouth Quest decided on a four point water column profile. The profile consisted of a surface sample, a sample at the top of the thermocline (20 meters), a sample at the bottom of the thermocline (30 meters) and a benthic sample (72 meters). As you would imagine it was a long day of sampling, and we are very interested in pairing PML’s extensive data collection at E-1 with our samples.

England, Here We Come!

In calm and clear conditions on May 11 Sorcerer II set sail for Plymouth, England.  We enjoyed our brief stay in the Azores, but we were all excited to get to the U.K. and complete our North Atlantic crossing.  As I mentioned in previous entries, we took samples near areas studied by the Department of Oceanography and Fisheries IMAR-University of the Azores (DOP/UAç).  We sailed from Faial to the neighboring island of Pico to collect the first sample.  On our second day out we collected another sample about 100 miles offshore.

On the second day of our five day transit we received word of bad weather on our projected route to Plymouth. With Charlie and John monitoring the forecasts from onboard Sorcerer II, and Craig monitoring from the US, the collective decision was made to head east to avoid the stronger winds and seas north of us.  We spent the day securing the boat and storing the science gear.  We had to travel so far east to avoid the heart of the storm that we were only 250 miles off the coast of Spain.  During this time we experienced winds up to 50 knots and seas ranging from 15-20 feet.  As you could imagine the weather put a halt to the sampling and the crew focused on the weather and making it to England safe and sound.

We arrived in Plymouth on Monday, May 18th two days later than expected, but happily in one piece.  Plymouth is a significant location for us since Charles Darwin embarked aboard the HMS Beagle from this same site 178 years ago.  As we sailed into our slip, we were greeted on the dock by Dr. Jack Gilbert, head of the Plymouth Marine Laboratory (PML) team and our host in Plymouth, and Dr. Mark Brown from The University of New South Wales (UNSW).  Dr. Brown (aka, Brownie) is a colleague who works on the Antarctic Lakes Project, a joint research program between UNSW and the J. Craig Venter Institute.  The Sorcerer II is in good hands with our hosts from PML.  We are all looking forward to some intense sampling in the coming days as well as a few nights of local food and fun with our UK friends and scientists.

Land Horta! The Sorcerer II on Faial Island, the Azores

We sailed into Horta on the island of Failal Saturday, May 9th around 1pm.  The Sorcerer II crew was excited to visit the island but then again, we were just happy to walk on land and sleep in a bed that was not rolling from side to side! As usual when we arrive in a new port, we cleared customs, arranged dockage, hooked up power, cleaned the boat and organized gear. Afterwards we arranged a tour of the island.

While I took in the sites and sounds of Horta from the back of the van, Karen our chef, sat next to the driver so had a much more detailed discussion about what we saw. Here is her account of this interesting island.

The guide, Louis took us up the closest old volcanic plug — Monta du Guia.  So called because of the guiding light of Virgin Mary to all the seafarers (guia means guide in Portuguese). Every August, there is a procession to the top to bring the image down from the chapel and put her in an old whaling boat and circumnavigate the mount. As you look down from the top, much volcanic activity is evident. There are two beautiful calderas and Monta Quemada (burnt mountain). Next we drove 900 meters to the highest point of the island to see another caldera — this one created from the main volcano that formed the island. Unfortunately the fog obscured everything so we had to take Louis’ word for it although he showed us a picture of something that looked like it could have been this caldera.

As we drove down the mountain we noticed two types of plants — blue hydrangeas that bloom in profusion in June and July and the other a Japanese cedar imported in the 1750s to be grown as a source of timber for the island. This cedar was used in making the windmills that we saw at the north end of the island.

There is little agriculture done on the island anymore because Louis told us it was so much easier and cheaper to get everything from the mainland EU.  I witnessed the lack of local produce when going to the supermarket to provision the boat. Fresh milk was especially impossible to find. We saw farmers and milk cans in trucks but we learned the milk was sent to the creamery to be made into butter and cheese which is much more exportable.

As we passed through a valley first populated by the Flemish, we saw the results of the 1998 earthquake. Large areas of houses were destroyed and the principle church ruined. Continuing along the road there were many small, quaint towns. In one the men were playing a traditional game which is a cross between the French game of boules and the Italian bocce. Every town has its own chapel dedicated to the Espiritu Santu and every year one family provides a typical meal of soup and beef to all the villagers and anyone who is hungry.

Next stop was the Calderinhas volcano. From September 1958 to November 1959 the volcano spat out smoke, lava and ash inundating the village houses, with the whaling station and lighthouse being especially hard hit.  The lava flows also created a new spit of land. Luckily no lives were lost but many, many homes were destroyed. As a result of this loss of property, approximately 30% of the population of the island fled to America with most of the people settling in the coastal whaling cities of New England. Since it was the Americans that brought whaling in to the Azores, many of the people on the island already had ties to those American cities and so the immigration wasn’t perhaps as shocking as it could have been. With our tour ended we said goodbye to Louis and left with a better understanding of these wild and rugged islands in the middle of the Atlantic.

Next we headed to see Dr. Sergio Stefanni from the Department of Oceanography and Fisheries (DOP) IMAR-University of the Azores, our science contact in the Azores, who offered to give us a tour of the facilities and research vessel.

The Department of Oceanography and Fisheries of the University of the Azores is a reference research center on deep-sea ecology, fisheries and conservation with a special interest in seamounts and hydrothermal vents. I was very impressed with the scope of research conducted there, and the state of art research equipment in the molecular, chemistry, optical, fisheries and oceanography labs. After the tour we asked Dr. Stefanni, his colleagues and some of the University’s graduate students to come visit our floating lab. While this team was onboard Sorcerer II, Captain Charlie and I took the opportunity to discuss the sampling sites we’d applied for in our permits. Dr. Stefanni and team explained to us some of the unique conditions around these sites such as the unusually warmer waters and the in-depth and long term chemical and oceanographic data for the one site, and the hydrothermal sulfur vents near the other which has been extensively studied by the Department of Oceanography and Fisheries. After the tour of Sorcerer II was completed and local sampling plan in place, the crew was given a tour of the Research Vessel, Arquipelago by the boat’s captain Manuel Fernando Serpa.

North Atlantic Transit

After four days in Bermuda reconnecting with colleagues at BIOS and preparing for sampling across the North Atlantic, Sorcerer II departed on April 29th enroute to the port of Horta located on the island of Faial in the Azores.  There are nine islands in the Azores archipelago which is governed by Portugal and is located 900 miles from the mainland.

Unfortunately, we had to leave Bermuda with no permits to sample in Bermudian waters. However, shortly after departure we received word from the Harbor Master via the VHF radio that our permits had been granted, and we could indeed collect samples. We located the BATS (Bermuda Atlantic Time Series) station, one of the sites that  we sampled for the original Sargasso Sea Science paper but Sorcerer II was already 20 miles past. Fortunately, by changing course, we were able to resample one of the sites from that first analysis.

As we traveled to the Azores, we gathered eight samples, collecting our deepest sample yet at 70 meters and doing our deepest open ocean water profile of 100 meters. The profiles revealed some interesting data, one being that the chlorophyll maximum was located at 70 meters.

On the North Atlantic transit weather played a key role on when and where we could sample. A few days out from Bermuda we were informed that a weather system was coming from the north, and we had to move south to avoid the brunt of it. I have experienced rough weather during my time aboard Sorcerer II, but the rough weather system we encountered was persistent. The crew had a few days of light wind and high seas; however, we did not have enough wind in the sails to keep us stable, and we just rolled from side to side. If you’ve ever experienced this kind of weather onboard a boat you know what it feels like and it’s tough to walk, work, eat, or sleep. The crew and I were not too happy during this period. Thankfully, the weather finally retreated, and the crew was rewarded with great winds the final days. Sorcerer II sailed into Horta comfortably with an average boat speed of 10 knots.

With this expedition, we’ve established a “mini” Science Series in which a visiting scientist presents his or her specific scope of interest. This was our chef, Karen McNish’s idea since as a former science teacher in the UK she has a keen interest in the science we do. Karolina Ininbergs one of our collaborators from Stockholm University talked about cyanobacteria, her favorite group of microbes. Virologist and JCVI board member, Dr. Erling Norrby joined the crew in Bermuda and hosted two nights of talks focusing on viruses and prions. Both of these scientists are impressive, and it was an honor for the crew to be exposed so intimately to their extensive research. On a personal level the series allowed me a deeper insight into Erling. He is an incredible man with a remarkable life’s work. It was a thrill to have him on this leg of the expedition, and he’ll be missed by the entire crew when he returns to Stockholm after docking in the Azores.

The transit from Bermuda to the Azores covered close to 2,000 miles and took 11 days. When we weren’t sampling, avoiding weather systems, on watch, or sleeping, the crew did enjoy a few hours of down time. We participated in some very competitive games of Hearts, the Sorcerer II game of choice. Despite the weather and work, we were also able to toast a milestone in the life of Captain Charlie Howard. We celebrated his birthday with a delicious roast dinner followed by cake and ice cream. Happy Birthday, Charlie!

All in all, the North Atlantic transit met my expectations of good sampling, good boating, good science, and good conversation. I am glad to have made the crossing safely, and we are all looking forward to our time in the Azores before heading to Plymouth, UK.

As they say in Faial, Até mais!
