Dublin is the largest city in Ireland, with a population of 1.3 million if the suburbs are included. The city is located where the River Liffey flows into the Irish Sea, the body of water between Ireland and Great Britain.

Norwegian ships have sailed into this river mouth for a long time. There is evidence of human activity here dating back to the Stone Age, and the first people to settle permanently were the Gaels in the 7th century, a people who lived across Ireland, Scotland, and the islands further north. But the city itself was established by Vikings just over a hundred years later and was named Dyflin. 

The river mouth was a perfect harbour for their longships, and it eventually developed into the Kingdom of Dublin – with a monetary economy and its own coins.

At the end of the 12th century, the Anglo-Normans took control of Ireland. 

At that time, the country consisted of several small kingdoms, but from then on Ireland was under English rule. Dublin grew rapidly during the 17th century and was for a short period the second largest city in the entire British Empire.

When Ireland became independent in 1922, Dublin became the capital. 

In addition to being the administrative centre, Dublin is an important industrial city and a centre for education, art and culture, and tourism. Dublin is an important cargo and ferry port, and many cruise ships also call at the city.

The River Liffey divides Dublin into two parts, and several smaller rivers and canals give the city a distinctive character. Outside the city there are low mountains to the south, otherwise flat grazing land - as in most of the rest of Ireland.

The proximity to the sea influences the climate. Summer temperatures are rarely much higher than 20°C, and winter temperatures are rarely lower than 4°C. 

The city lies on the east side of Ireland, and since most of the rainfall comes in from the west, it is much drier here than on the west coast. Over the course of a year, Dublin normally receives 772 mm of precipitation.

Average maximum temperature in April: 12.3 °C
Average rainfall in April: 55 mm

Storetveit School lies beside a park just south of Bergen city centre. The first spring flowers are only just beginning to appear on the day we visit, but it is chilly, and the hills surrounding the city are still dusted with snow.

Students in the 8th and 10th grades are making messages in a bottle. Not letters asking to be rescued from a deserted island, but still cries for help - on behalf of the ocean. Their messages are about rising temperatures, ocean acidification, rising sea levels, microplastics and ghost nets - lost, but still catching fish.

The messages the students are working on are part of the “Message in a Bottle” project. The project was launched by Statsraad Lehmkuhl as part of the One Ocean Expedition. Drew School in San Francisco embraced the idea and developed teaching materials and a set of assignments.

Teachers and students can participate in digital meetings with the researchers on board and gain access to data collected during the expedition. The result is that a new generation is learning about the ocean, climate and sustainability in an engaging and exciting way.

The "bottles" made by class 10E contain videos. Their teacher, Magnhild Hauge Oppedal, first gave the students the necessary background, and then complete freedom to choose what message they wanted to share - and how they wanted to communicate it.

Agneta Bergstrøm Vågenes kneels on a chair in front of a whiteboard. The group discusses for a moment, Agneta nods and starts drawing. First the sun, then greenhouse gases as clouds. A tablet is set up to photograph the board. Lines illustrating heat from the sun are added, another photo is taken, more drawings are added, and more photos follow.

– It’s going to be a stop-motion video about rising sea levels, says Hedda Brunstad Løvold. But first we have to explain why the ocean temperature is rising.

The classroom is surprisingly calm. The students talk quietly together and type on their laptops. Sonja Elise Engebretsen is the only one working with paper and pencil.

– We want to use a real message in a bottle in the video we’re making, she explains. This is the letter that will go into the bottle that we’ll film ourselves throwing into the sea.

Before sitting down to write the letter, she worked on the storyboard for the video - small boxes with sketches showing how the group imagines the story unfolding.

One group has taken on a tough task, they want to confront politicians.

– Politicians talk a lot, but they don’t actually do anything, says Isabel Bendiksen Holtung, frustrated. Her challenge is how to reach them. Could they just go down to City Hall with a camera and ask for an interview?

The students are creative. One group wants a fish to be the narrator in their video, a real, live fish.

– Where can we easily film a fish swimming around? Andrea Lone Hansen wonders. Maybe at the Aquarium at Nordnes? The others nod enthusiastically.

We walk further down the corridor to class 8C. Here the noise level is higher - in teacher Paal Bergh’s classroom there is sawing, painting and modelling going on.

Paal has built display cases from wood and plexiglass, and the students are filling them with stories. Expanding foam becomes the seabed, populated with fish, crabs, corals and other organisms. One display case will tell the story of pollution, warming seas and coral death. Another will show nets and traps that are lost and remain in the ocean, where they continue to catch fish and shellfish, before eventually turning into microplastics after many years.

Luna My Bergsvik has 3D-printed a boat and painted the hull bright red. Now she is sawing a thin strip into short pieces.

– It’s going to be a ghost trap, she says. A lost trap, lying there killing crabs and lobsters.

Christoffer Hove has made a swordfish from modelling clay and is painting it. In front of him lies a fish book opened to the right page, the colours have to be correct. Josephine Emilie Valkner is wrapping string around a round shape. She turns it slightly to glue the string in place, and then we see it - a whale.

Johan Ludvig Halvorsen Kårbø holds up a thermometer made of wood. The red temperature column made by clay reaches all the way to the top. His group is working on the consequences of a warmer ocean. Jatin Yalamanchili has built a model of the “rosette”, the ring of tubes that is lowered from Statsraad Lehmkuhl to collect water samples deep below the ship.

Matilde Brosvik sits cross-legged on a desk with her group, typing intently on her laptop.

– In front of the display case there will be a small information booklet, she explains. This will be the text in the booklet.

The messages in bottles created by the students at Storetveit School will be formally presented to Captain Marcus Seidl on April 20 during a special youth event on board the ship. Students from Metis Upper Secondary School in Bergen will also participate.

Similar presentations have taken place in several of the ports visited by Statsraad Lehmkuhl during the expedition. All the contributions have been brought on board, and a selection of them will be exhibited and can be experienced in the building at Statsraad Lehmkuhl’s permanent berth at Bradbenken.

The exhibition opens April 18, the same day Statsraad Lehmkuhl arrives in Bergen, and will be free and open throughout

Brest lies as far northwest in France as it is possible to go. The Brittany peninsula reaches out into the Atlantic Ocean where the Bay of Biscay meets the entrance to the English Channel.

The city is well sheltered in the bay known as the Rade de Brest, inside the narrow strait called the Goulet de Brest. The strait is only two kilometres wide, and the tidal current flowing in and out of the bay can reach speeds of 4–5 knots. Sailing ships approaching the harbour often had to wait outside at Camaret-sur-Mer if the current was against them.

Brest has long been one of France’s most important ports. Today it is one of the country’s main naval bases, together with Toulon on the Mediterranean coast.

The city was originally established as a fortress in the Middle Ages. It later grew around the naval base founded there in 1631.

During the Second World War France was occupied by Nazi Germany, establishing a submarine base and a shipyard in the city.

After the Allied landings in Normandy in June 1944, securing French ports became crucial so that equipment and supplies could be brought ashore, Brest being one of them. Allied forces reached Brest on 7 August, and on 25 August the city was attacked.

The fighting was intense, and when the German general Ramcke surrendered Brest on 19 September, large parts of the city had been destroyed.

After the war Brest was rebuilt and is today an important university city. The French Naval Academy is located here.

The city is also a centre for marine research, through the French Research Institute for Exploitation of the Sea (Ifremer) and the French Polar Institute.

Today Brest has a population of just over 140,000. In addition to jobs connected to defence, research and education, many people work in shipping and the service sector.

The proximity to the sea influences the climate. Summers are relatively cool, and the city receives about 1,230 millimetres of rainfall each year, most of it between late autumn and early spring.

Average maximum temperature in April: 13.9 °C
Average rainfall in April: 92 mm
