Résumé
The current study aims to explore the seasonal variability of the hydrographic structure of Sharm Obhur. It also aims to estimate the Sharm heat balance and exchange with the Red Sea and describe the comprehensive hydrographic structure of Sharm Obhur. The analysis in this study relies on the two years (CTD) and current measurements using (ADCP) alongside meteorological data. The research is conducted by analyzing year record from April 2015 to March 2016 of the hydrographic information and the current profiles aligned with meteorological information. The study used (8) hydrographic stations along the central axis of the Sharm for the measurement of salinity and temperature. The study shows surface inflow from the Red Sea to Sharm Obhur and subsurface outflow from the Sharm by examining the average current velocity. The net heat fluxes estimation shows an annual surface heat loss of 49 W m−2 which is balanced with a heat gain of 49.9 W m−2 from the annual mean heat advection. The study also concluded that the average temperatures, salinity, and density during spring 2015 are the highest compared to the rest of the years for the same period, as they showed an average of 25.72 ° C, 39.27 PSU for each of the temperature and salinity respectively. In summer, the general average of hydrographic data shows higher values in 2016 for temperatures and salinity. During the autumn and winter of 2015, it was the highest of the years’ protection for the same period, with 27.81 ° C and 39.41 PSU for each temperature and salinity respectively.
