The phrase: If you ignore the names of things, it disappears also what you know about them.
Carl Linnaeus (1707-1778)
Background sound: fishing soundscape: birds, boats, sea, people, etc.

1. Ocean Currents: The Ocean contains 99% of the planet's living space. Life emerged and evolved in the sea. The temperatures of the oceanic masses vary only slightly, and water salinity (3.5%)
- The temperature of the oceans and land (map)
- Salinity: Fresh water and salt water. 97% of the planet's water is salt water. Most of the other 3% is frozen. (picture)
- The sea currents: according to the position of the planet, day and night, the seasons, and the rotation and translation of the Earth, there are various climates, varying according to the seasons and zones. This set of forces and movements causes tides and water currents as temperature, are shallow or deep. These forces also cause movements and air currents, depending on the height, temperature and speed. They present as soft breeze, or as devastating and deadly typhoons, hurricanes, cyclones and tornadoes.
Expository Items: start with 'the wave' and make a soundtrack introduction to the exhibition:
- In one of the walls 2 National Geographic Maps: ocean currents, water temperatures and onshore winds, and with color changes make the difference between winter and summer. And a video explaining them Manuel González (Azti-Tecnalia)

2. The oceans as communication routes. Navigation: Finding our way in the sea. Orient ourselves with the sun and stars: stars at sea and in the sky astronomy, learns to find you.
Macrocosm and microcosm: tiny organisms that are found in every drop of water that is extracted from the sea can be seen in the wonderful world that shows the microscope. And in that same sea, they are also more burly animals who live on the planet.
Expository Items: Magnifiers airships as porthole windows of a ship to see microorganisms as giants, allowing see them in different sizes and at different scales. Mandatory: Otolith and photos of eggs and larvae of cod.
- Overhead a projection of stars on a Fuller geodesic dome made of black cardboard, projecting Starry Night November 20, 2003, when it was opened the Maritime Museum in Bilbao. Honningsvag and Stavanger will choose the date that they wish to project. We will post a round dome with 360 degrees marked on the roof and we will propose to the people reach the North or the South... and seek references through the senses: smell, hearing, touch ...
- Cod, like other fish, are oriented thanks to the otoliths: magnifiers will post some audio teach and explain. I think in the otoliths and circles of tree trunks: touch the trunk and tell its age. The age of Atlantic cod is determined by counting the growth rings that make otoliths two tiny calcareous elements located in the inner ear, which becomes much like counting the rings of a tree, they tell us, even if it has been year of very cold water.
- Maritime Soundscape
- Pressure sensors and water presence and diffusers
- Smell of the sea
- Touch: logs of different woods and explanation. Another way of reading. Read in nature.
1. Landscape, cliffs and beaches in the Arctic and the Atlantic coast, types of algae, drying, saliniad, banks, farms.
Expository Items: landscape pictures on textures, colors, smells ... not saying places... and guess with what they knew. And then with what they already know.
2. Flora and Fauna: The same ocean sets land boundaries, all around the European continent, and determines the flora and fauna along the coasts washed by the ocean, with its Salinity, point of, different temperatures and the currents that soften some highs. And amid all: seabirds.
The marine flora and fauna depend on light, depth, temperature, salinity,, dissolved oxygen, tides, currents, concentration of nutrients, type of bottom, distance from shore, distance to the bottom...
Expository Items: birds wall: The idea is to simulate two rocky walls, one is a cliff in the Arctic and other coastal cliff Bizkaia, with images of birds cut and placed on foam board, by way of stickers ... composing a painting in relief with varying distances, but on rock photo. With the birds that we see most often in the Norwegian coast and in ours, we have already contacted the Society ornithologists who have sent us pictures of birds of both cliffs and the sounds of the birds.
3. Biodiversity and ecosystems: Biodiversity is the key to tackle some of the world's biggest challenges: climate change, sustainable development and food security. There are areas of great ecological value that must remain active for future generations. In addition to rising temperatures and decreasing sea ice in the Northern area, will increase industrial activities in the area (eg oil, gas industry and shipping).
Natural capital: ecosystems, biodiversity and natural resources, are what sustains the economy, society and individual welfare.
- Aquatic Ecosystems: depending on the water: fresh / salty, and marine ecosystems: sandy, rocky, sea coast and open sea, to which they belong different fish
- Seasonality of renewable natural resources: the months of spawning and rearing, ban, etc...
Expository Items: Something similar to:
4. Similarities and differences with other fish:
- Difference between freshwater fish and saltwater
- Difference between white fish and oily fish
- Difference between deep-sea fish and surface waters
- Differences between fish and shellfish
Expository Items: An animation with "spot the differences" or puzzle pieces that only fit in the correct answer. Or wooden pieces that make up a correct figure if grouped corresponding to the same category ... (learn the basics of classification, first step of scientific knowledge):

1. Technical details of the cod and its records: Besides its chemical and nutritional composition, it is good to know their measurements and their records. It measures from 35 cm to 2 meters, with an average length of 1 m. Its weight varies from 3 to 100 kg and the maximum weight known is 96 kilos and maximum age 25 years. During the autumn leave pelagic habitats and sink to the bottom, which suggests to some scientists that cods hibernate.
Expository Items: Round tube, transparent and from floor to ceiling with the percentages of their chemical composition: Magnesium, water, potassium, etc.. and a second tube in comparative format with the chemical composition of the human body. Panel with photos of some spectacular specimens. Find similarities between cod and other species of fish, or between cod and other elements in nature.
2. External anatomy of cod: Type skeleton, his head teeth, eyes, tongue, Kokotxa, etc.., The body: the caudal peduncle, types of fins, tail, shape and purpose, the skin, the shape of the scales , spines and rays, how to they swim, how they float and rise to the surface and descend to the depths of the ocean, different body colors. The lateral line, form and purpose, cod, and other fish, is on the side of the body with a "sideline" that allows them to detect movement in the water. The lateral line can also help even know where they are in the currents.
Expository Items: I think of a 3D game in which you have to perform three movements: horizontal circular, circular lateral circular vertical and go in a straight line. Probably is interesting to develop some APP so it can be downloaded.
3. Internal Anatomy: swim bladder, respiratory system, water balance, the digestive system, the liver, nervous system, brain and cerebellum, circulatory system, muscular system, the senses, the sensorial apparatus itself, inner ear, smell, etc.. The otoliths: the black box of cod and of the ocean!
Expository Items: a board with a matrix of turntables to provide information for each item, its value, its location and its image
4. Parts of cod: leather, gelatin, meat, scrape, kokotxas, roe, liver, intestine, otoliths: cod black box.
Expository Items: Explanatory panels, photographs, textures, videos and soundscape textures.
5. Its scenario: adaptation to the environment, where its move and how, banks, migration, qualities depending on the salinity, the effect of temperature on growth, etc.The Atlantic cod can change color at certain depths. The cod has two different color phases: gray-green and reddish brown.
Expository Items: Stroboscopic light games
6. Its feeding: The food chain as nutrients and energy exchange between species in an ecosystem. The cod can getting to eat their pups, they are active hunters, feeding on sand eels, whiting, haddock, small cod, squid, crabs, lobsters, mussels, worms, mackerel, and molluscs.
Moreover, the gradual disappearance of high trophic level predators such as Atlantic cod (Gadus morhua), can cause trophic cascades are altered in composition and abundance of living communities associated with the seabed. Therefore, direct and indirect forms of human intervention can affect biodiversity small and large spatial scales.
Expository Items: Play with sensors and Arduino board
7. How to is reproduced: Distribution and spawning areas. How often and how many eggs, how they mate and where, geographically and locally. Number of cod eggs. Seasonality. Success, concentration, etc.
Expository Items: Maps and explanatory video of women scientists...
8. The Skrei: and its special organoleptic characteristics. They migrate from the cold waters of the Barents Sea in Norway to the Lofoten Islandsto which goes to spawn. In these islands is where it is captured in the colder months of the year. The skrei need to accumulate fat, which causes it to have special organoleptic characteristics, such as a more intense flavor and a juicier meat The long journey that takes, makes the fish increase their muscle, which provides to the white meat a texture smoother, and a special white pearly luster In addition, food that feeds mainly seafood, minerals gives that are manifested in its flavor.
