Subtidal response of the scotian shelf bottom pressure field to meteorological forcing

Abstract

0.5 cpd and at locations on the eastern half of the shelf, but plays an important role at all sites and at all frequencies. These variations propagate to the west at speeds of 6.5 (ω < 0.2 cpd), 25–33 (0.2 cpd < ω < 0.5 cpd), and 12–17m s−1 (ω > 0.5 cpd). The exponential decay scales at all frequencies are ∼900 km in the direction of phase propagation. The non‐local response is consistent with theoretical estimates of first‐ and second‐mode shelf waves for this region and represents the most direct evidence of shelf wave activity on the Scotian Shelf to date. © 1989 Taylor & Francis Group, LLC.
