Environmental Correlates of Arctic Ice-edge Noise

Abstract

Temporal variations of low-frequency, broadband ambient noise measured in early summer under drifting ice floes of the marginal ice zone (MIZ) are cross correlated with local environmental forces and ice field descriptors. Surface gravity wave forcing is the primary correlate of the noise; its interaction with ice floes generates sound, most likely via flexural flow failure, and unloading motion, within a few kilometers of the ice edge.
