Measurements of wave damping by a grease ice slick in Svalbard using off-the-shelf sensors and open-source electronics
ABSTRACT Versatile instruments assembled from off-the-shelf sensors and open-source electronics are used to record wave propagation and damping measured by Inertial Motion Units (IMUs) in a grease ice slick near the shore in Adventfjorden, Svalbard. Viscous attenuation of waves due to the grease ice...
