The warm Norwegian Current passes through the Norwegian Sea and renders it ice-free. In most parts of the sea the temperature of the water is 2°–7°C in February and 8°-12°C in August. The salinity is 34–35. 2‰. The Norwegian Sea has semidiurnal tides, measuring up to 3.3 m. It is rich in fish (cod and herring). The main ports are Trondheim, Tromsø, and Narvik (Norway).
