Rockweed (Ascophyllum nodosum) is found growing in the intertidal zone and is common over much of the North Atlantic. It is perennial, growing on large stones and rocks and may reach 1,5 m in length. The species thrive better in areas exposed to air during low tides and fairly exposed or in sheltered areas.

Rockweed is the most common species around Icelandic shores. It is very sensitive to pollution and can be an indicator of environmental cleaniness. Conditions at Breidafjordur are very favorable for this species.

Kelp (Laminaria digitata) is one of the largest seaweeds found along the European littoral, mature plants being 1-2 m in length, and is common over northern Europe. The Kelp is composed of a smooth and pliable stipe and a blade of jagged ribbons. The plants are attached to boulders by holdfasts in the lower intertidal and shallow subtidal down to a depth of 20 metres. The Kelp flourishes in fairly exposed or in sheltered areas.
