Tidal Salinity and Temperature
Pore water pressure and temperature variations were measured with regard to local hydrodynamic forcing and possible sediment transport. A vertical array of pressure and temperature sensors was deployed at sediment depths ranging from 5-60 cm at a steep, mixed-sand-gravel, mega-tidal beach in Advocate, Nova Scotia, Canada. Temperature variations seemed to be associated to three processes: infiltration-exfiltration of water into the beachface, energy dissipation due to wave breaking, and air ventilation. In summary, the presented method seemed promising with regard to obtaining complementary information regarding the interaction between surface water and ground water in the intertidal zone.
