Abstract

In the framework of the EMRP project “ENV 58. Metrology for essential climate variables”, a new technique to perform traceable temperature measurements of the sea water profile and sea water surface will be studied, developed and applied to a real situation. This new thermometer consists on several Bragg gratings located at different points along an optical fiber, getting a thermometer based on distributed temperature sensors, that will be used to measure the sea water temperature profile. This technique will provide additional and valuable information about the evolution of the sea environment behaviour.
