TL;DR: In this article, evidence indicates that resuspension of oxidizable bottom sediments in a tidal waterway caused significant reductions in the dissolved oxygen (D.O.) concentration of the water.
Abstract: Evidence indicates that resuspension of oxidizable bottom sediments in a tidal waterway caused significant reductions in the dissolved oxygen (D.O.) concentration of the water. During dredging, D.O. was reduced between 16–83% below normal.

TL;DR: In underwater dredging, the ambient pressure in the soil or sand being dredged adjacent the tip of the dredging pipe which is buried in the sand is used to control the machinery so that the output of dredged material is increased as mentioned in this paper.
Abstract: In underwater dredging, the ambient pressure in the soil or sand being dredged adjacent the tip of the dredging pipe which is buried in the sand is used to control the dredging machinery so that the output of dredged material is increased. A pressure sensitive device is used to anticipate variations in concentration of the sand in the suspension of sand in water being dredged.
