coastal measurements

dissolved oxygen

A remotely operated model ship has been constructed to provide a mobile platform for measurements in the coastal waters. on board both dissolved oxygen and water temperature microcomputer probes as well as data loggers along with a water pump were deployed. This set-up allowed us to cross the coastal breaking wave zone and trace both oxygen and water temperature with a frequency of 1-15 seconds, as well as to collect samples of subsurface water. The constructed model was successfully used under conditions of high wind speed and during the winter, when measurements in coastal waters are most difficult and dangerous. Data on dissolved oxygen distribution showed enhanced oxygen evasion taking place within the breaking wave paths along the coastal barriers. Results indicate that breaking waves control the dissolved oxygen and other gaseous content in the coastal surface waters as well as their water-to-air fluxes.
