MEASUREMENTS OF DIFFUSIVE SUBLAYER THICKNESSES IN THE OCEAN BY ALABASTER DISSOLUTION, AND THEIR IMPLICATIONS FOR THE MEASUREMENTS OF BENTHIC FLUXES Academic Article uri icon

abstract

  • A simple method to compare flow levels consists of measurements of gypsum dissolution rates inside benthic chambers and on the sea floor. The measurement of the diffusion-controlled dissolution rate of gypsum allows the estimation of the diffusive sublayer thickness and the time-averaged bottom stress on the seafloor. This method had previously been intercalibrated with the stress sensor method in flumes and inside benthic chambers. We describe here free-vehicle deployments of alabaster plates on the bottom of the ocean which gave results consistent with hydrodynamic theory. -from Authors
