Abstract
  • Highly resolved pressure measurements on the seafloor over New Jersey’s continental shelf reveal the pressure signature of nonlinear internal waves of depression as negative pressure perturbations. The sign of the perturbation is determined by the dominance of the internal hydrostatic pressure (p⁰Wh) due to isopycnal displacement over the contributions of external hydrostatic pressure (ρ₀gηH; ηH is surface displacement) and nonhydrostatic pressure (p₀nh), each of opposite sign to p⁰Wh. This measurement represents experimental confirmation of the wave-induced pressure signal inferred in a previous study by Moum and Smyth.
  • There was a press error in Fig. 10 of Moum and Nash (2008). The legend in Fig. 10a was shown in black and white instead of color. The correct figure and caption as they were meant to appear are shown below. The staff of the Journal of Physical Oceanography regrets any inconvenience this error may have caused.
