Habitat and biocoenosis descriptions of hard-bottom sublittoral sites in high-arctic Isfjorden, Spitsbergen—Supporting data

Through integrating various methodologies and focusing on some environmental variables we describe three long-term monitoring sites from northern (N) and southern (S1, S2) Isfjorden proper (78°N Spitsbergen) along the hard-bottom littoral, infralittoral, and upper circalittoral (<30m) zones using a seascape ecology approach and standardised classification schemes.
