Notes: The climate normal is the three-decade average of climatological variables from 1981 to 2010. Winter data are from January to March with other seasons following sequentially. Areas classed as coastal have a maximum depth of 50 m, the epipelagic class has depths from 50 m to 200 m, the mesopelagic class has depths from 200 m to 1,000 m, the bathypelagic class has depths of 1 km to 4 km and the abyssalpelagic class includes all areas with depths of more than 4 km.
