The Ocean is under unprecedented local and global challenges (IPCC, Reference Fiels, Barros, Dokken, Mach, Mastrandrea, Bilir, Chatterjee, Ebi, Estrada, Genova, Girma, Kissel, Levy, MacCracken, Mastrandrea and White2013). This increasing destruction and pollution subsequently threatens humankind by putting at risk the countless services provided by marine ecosystems. In the face of global changes such as warming and ocean acidification, only collective actions can lead to the needed mitigation and adaptation measures. These will necessitate public understanding of both the marine realm and global changes as well as a strong will to act upon challenges or accept the required political and economic changes. This is a real challenge as many features of the ocean are difficult to experience because they are too small, too big or too abstract. When it comes to global changes, we are also faced with concepts that are somewhat difficult to comprehend. These can be invisible, geographically or temporally distant, and it is then tempting to ignore them. This led to the increasing interest around the world in developing citizens’ ocean literacy, the ‘understanding of the ocean's influence on you and your influence on the ocean’ (Cava et al., Reference Cava, Schoedinger, Strang and Tuddenham2005). Being ocean literate implies being able to address marine issues in order to develop solutions and actions adapted to our culture and values (Dupont & Fauville, Reference Dupont and Fauville2017). Working closely with educators and communicators, scientists can play a key role in moving toward a more ocean literate society. For this purpose, scientists need to be better trained in various form of communication, including strategies derived from psychology, sociology and have a deeper understanding of stakeholders’ cultures (Dupont et al., Reference Dupont, Puncher and Calosi2015). There may also be a need for more fundamental changes in the way science is performed. For a more effective form of scientific communication, we may need to deviate from the linear science supply paradigm and rather produce some science directly targeting societal values (e.g. Dupont et al., Reference Dupont, Hall, Calosi and Lundve2014, Reference Dupont, Puncher and Calosi2015).

Being more ocean or environment literate does not necessarily translate into positive actions. For example, Kahan et al. (Reference Kahan, Peters, Wittlin, Slovic, Larrimore Ouellette, Braman and Mandel2012) showed that increased science literacy did not lead to consensus but promoted more polarization on climate change issues. The reason behind this gap between environmental knowledge and pro-environmental behaviour can be attributed to many external and internal parameters. However, emotional involvement is often identified as a key factor shaping environmental awareness and attitude (see Kollmuss & Agyeman, Reference Kollmuss and Agyeman2002 for review).

One of the characteristics of the arts is their ability to evoke emotions. Art can provide an open forum where science, nature and society can reconnect, working on our senses, emotions and values. Scientists who are exposed to art to communicate their science generally agree that it creates a constructive atmosphere, an alternative way of sharing their knowledge, including a simpler way to explain complex scientific concepts, as well as an opportunity to self-reflect (Curtis et al., Reference Curtis, Reid and Ballard2012). When successfully combined, arts and sciences can lead to self-realization and reflection as well as a will to take actions. As an example, the artist Chris Jordan made a picture inspired by a watercolor painting by Sarah Miller. This 64″ × 94″ piece viewed from a distance represents two sharks. Closer inspection reveals that it is made of 270,000 fossilized shark teeth corresponding to the number of sharks killed every single day for their fins (Worms et al., Reference Worms, Davis, Kettemer, Ward-Paige, Chapman, Heithaus, Kessell and Gruber2013). This provides a visual understanding of the enormity of this number and can be a first step toward a better understanding of the issue.

To explore the idea that the arts and sciences can help to physically and emotionally connect citizens to marine global changes and to lead to an effective way to drive and support the required collective actions, I (as a marine biologist) teamed up with the artist (musician, poet, adventurer) Henrik Wallgren. We worked in the context of a European project coordinated by Maria Mebius Schröder from TILLT (http://www.tillt.se/en-GB) and funded by the Swedish Institute. The aim was to combine the arts and sciences to facilitate knowledge transfer and increase awareness and values about the marine environment in young citizens. We designed a two half day activity that was tested on 32 high school students from the Donnergymnasiet school (Gothenburg) and presented to marine communicators in November 2016.

Our approach was to use sensory immersion as a way to create a strong connection between the ocean, global change science and individuals. We combined guided discussions with field trips. Discussions encourage critical thinking, scepticism and allow students to take ownership of ideas and arguments and are also a way to develop a personal connection with a topic (Zeidler, Reference Zeidler1997). Field trips promote contact with the ocean and are postulated to have a positive impact on specific aspects of learning (e.g. Ramasundaram et al., Reference Ramasundaram, Grunwald, Mangeot, Comerford and Bliss2005). For example, Stepath (Reference Stepath2006) showed that a field trip to a coral reef caused significant modification in high school students' environmental attitudes and intention to act.

The activity was divided into two parts. The first day, the students were asked to discuss and reflect on the role played by the ocean in their everyday life. This also included consideration of the many threats that humans pose on marine life. Students were then challenged to be the ocean for one week. As a first task as the ocean, they were asked to eat a mysterious red soup and pay attention to consequences on their body when back home. Alternatively, when presenting our activity during a lunch seminar, we asked the adult participants to be the ocean and blindly drink a ‘blue shot’ without knowing the content (Figure 1). The goal of this exercise was to give the participants a sense of the fact that the ocean is passively suffering from human pollution. The soup was a beetroot borscht and the blue shot was water with a harmless food colouring. Eating beetroot soup caused the excretion of pigments that colour urine in red or pink. This was used as a sensory metaphor (fear of taking an unknown substance and/or observing the consequences on their own body) of the fact that pollution is not without consequences, a realization that the students had when back home and that was discussed at the beginning of the second day.

The second part of the first day of the activity was a ‘behind the scene’ tour of the Sjöfartmuseet Aquarium in Gothenburg (Figure 2A). Students had both a hint of the beauty of the ocean as well as a better understanding of the complexity that underlies good water quality and hence the health of marine life.

The second day focused on solutions. It started with a few outdoor activities where students had to brave the bad Swedish weather to go on a rowing boat and collect capsules containing solutions to global changes hanging on a structure in the middle of the harbour (Figure 2B). When back on land, they could open the capsule to discover that it only contained a blank page. For the rest of the activity, they were asked to work in small groups to fill up this page. They had to focus on what they care the most about in the ocean, reflect on what were the main associated threats and provide at least one solution each.

When asked what they cared about the ocean, only a minority of the students mentioned socio-economic services such as food or climate feedback. Most of them rather highlighted the inner beauty of the marine realm and the need to preserve it for future generations. They proposed many creative solutions from recycling to drastic lifestyle changes. However, the most inspiring aspect of the activity was the tangible passion inside the group. By combining a sense of wonder (e.g. the visit of the aquarium; Figure 2A), a physical realization of the impact we have (e.g. the blue shot experiment; Figure 1) and appropriation of problems and solutions (Figure 2B), all the participants, including the organizing team, were sharing a unique passion and will to act. Some students expressed their interest in becoming marine biologists or in starting actions at school and at home to decrease their carbon footprint.

Scientists have little time and often little academic reward for scientific communication. However, they often share with artists a real passion for their work. Taking the time and the risk to move out of our comfort zone to take the challenge of working with artists and students is a truly transformative experience and a step toward moving from ocean literacy to a real passion for the ocean.
