The coastal areas, which extend up to one nautical mile outside the baseline, house rich<br />

ecosystems, both at the bottom and in the water column above – the pelagic. Inputs of<br />

nutrients from land, the shallow areas that receive light from the sun, and the stirring<br />

of water layers in different seasons are conditions that make the coast highly productive<br />

compared to the deeper waters further out. The bloom of phytoplankton in the<br />

spring provides large quantities of food for small unicellular and multicellular organisms,<br />

including ciliates and copepods. These in turn are eaten by predators such as zooplankton,<br />

fish and jellyfish, but also by polychaetas, clams and other animals that live<br />

on the sea floor. Kelp and seaweed grow on hard substrate, forming marine forests that<br />

dominate the part of the seabed that receives sunlight. These forests provide food,<br />

breeding- and feeding places for a myriad of other species of algae, large and small<br />

crustaceans, snails and fish. Mollusks, crustaceans and polychaetas hide in the vegetation<br />

and are food for fish both inside and outside the kelp forest. Many fish species live<br />

their entire lives on the coast, while others come to the coast to eat or spawn. The great<br />

access to food forms the basis for life of rich populations of seabirds, seals and whales<br />

along the coast, and these populations are completely dependent on the coastal ecosystem<br />

in order to survive.<br />

2.1 The North Sea and Skagerrak<br />

The North Sea and Skagerrak region is one of Scandinavia’s most intensively exploited<br />

seas and is among the world’s busiest sailing areas. The use of the seas creates great<br />

values for the Norwegian and Swedish societies. The North Sea is particularly productive<br />

and supports extensive fishing, from small coastal fishing vessels to huge trawls,<br />

and at the same time Skagerrak is particularly important for small scale fisheries.<br />

Many different activities with several conflicting interests create challenges for the<br />

management. The main industrial activities in these waters are currently fisheries, shipping<br />

and petroleum industry as well as tourism. The majority of the Norwegian oil and<br />

gas production takes place in the North Sea. Other industries include possible future<br />

offshore energy, marine bioprospecting and mineral exploration on the seabed (Meld.<br />

St. 37, 2012–2013, HVMFS 2012:19).<br />

Sea and coast has great importance for recreation, outdoor activities, and tourism in<br />

Scandinavia. The coastline is very attractive and widely used by Scandinavians and their<br />

tourists (Naturvårdsverket 2008). Coastal and marine environment is important for sport<br />

in that it provides adventure value, as it is a place to exercise activities, providing health<br />

effects, thus making it an important basis for local and national economic activity through<br />
