Abstract This thesis examined the decadal hydrographic shifts in the Red Sea and Gulf of Aden from 1951 to 2020, focusing on sea temperature, salinity, and density. Chapter 2 presented data sources, methods, and trends calculation using Ocean Data View and linear regression model. The Red Sea and Gulf of Aden experienced notable temperature fluctuations over seven decades, with sea surface temperatures rising, especially in the last decade. Salinity varied, trending upwards in the Red Sea’s north while remaining stable in the Gulf of Aden. Potential density changes reflected temperature and salinity dynamics, showing gradients in the Red Sea and denser waters in the Gulf of Aden’s south. Seasonal temperature, salinity, and density shifts were distinct in the Red Sea, with varied water masses influenced by Gulf of Aden exchanges. Decadal trends indicated warming temperatures in both regions, with nuanced salinity and density patterns across seasons, particularly in the Red Sea’s northern areas. |
