Table 1 The depth threshold that various baleen whale species should swim below in order to avoid the impact of wave drag close to the surface

From: A week in the life of a pygmy blue whale: migratory dive depth overlaps with large vessel drafts

Species Length (m) N Girth max (m) Diameter (m) Wave drag depth threshold (m) Wave drag depth-rounded threshold (m)
Blue whale (Balaenoptera musculus) 24.72 3 12.19 3.88 11.64 12
Humpback whale (Megaptera novaeangliae) 13.5 29 10.08 3.21 9.63 10
Gray whale (Eschrichtius robustus) 12.29 5 6.86 2.18 6.54 7
North Atlantic right whale (Eubalaena glacialis) 15.02 10 10.3 3.28 9.84 10
Antarctic minke whale (Balaenoptera bonaerensis) 8.36 2872 4.28 1.36 4.08 4
  1. Data on the girth of whale species were taken from [73] (Antarctic minke whales) and [74] (all other species). Diameter is calculated from girth by assuming a circular shape. The wave drag depth-rounded threshold is calculated to represent the level of accuracy of the pressure sensor in the biotelemetry device used in this study
