Bank Sea area of positive bottom relief where the water is relatively shallow, but normally sufficient for safe navigation. The term may also be applied to a small nunatak or other land feature.
Basin Synonymous on land with cirque, or an almost landlocked body of water off an inlet or sound, but the term in English form in the latter sense does not arise in this work.
Bastion Upstanding rock feature, often with cliffs on at least one side and usually outlying a larger feature, cf. buttress.
Bay Properly a comparatively gradual indentation of the coast-line, the seaward opening of which is usually wider than the penetration into the land, but often applied more loosely, cf. bight, firth,fjord, gulf, inlet.
Beach Ice-free length of shore, gently sloping and free of rock outcrops or material above cobble size.
Beacon Conspicuous hill.
Bench Similar to terrace but usually applied to a smaller feature.
Bight Crescent-shaped indentation in the coastline, of relatively large extent, cf. bay.
