The long-term goal of this program is to understand the processes by which heat and mass are transported vertically by turbulent processes in the ocean in order to estimate the rates of these transports. Our ongoing studies of both the kinematics and dynamics of turbulence and other smallscale physical phenomena in the ocean emphasize observations, a continual program of sensor and instrumentat...

Increases in transepithelial solute permeability were elicited in the frog skin with external hypertonic urea, theophylline, and vasopressin (ADH). In external hypertonic urea, which is known to increase the permeability of the extracellular (paracellular) pathway, the unidirectional transepithelial fluxes of Na (passive), K, Cl, and urea increased substantially while preserving a linear relati...
