This study offers insights into the wave climate of the Gulf of Guinea (GoG) and its past and future trends under various climate change scenarios. Using linear regression and difference analysis, it examines changes in average and extreme wave heights (Hs), wave periods (Tm), and wave direction (Dm) across the GoG. The findings reveal a consistent...

In an effort to enhance the resilience of coastal communities against the increasing impacts of climate change—resulting from a complex interplay of land, marine, and atmospheric factors—this study seeks to analyse the historical and future trends of these changes. Recognizing that shifts in air and water temperature directly influence wind pattern...

This study investigated the historical and future wave power potential in the Gulf of Guinea (GoG) with the aim of identifying high-density wave energy locations for potential exploitation. To estimate wave power density (WPD) for three time periods (past: 1979–2005, mid-century: 2026–2050, and end-century: 2081–2100), we utilized significant wave...

The densely populated coast of the Gulf of Guinea (GoG) is experiencing escalating erosion from climate change (CC). To assess Longshore Sediment Transport (LST) changes in the past and future, an empirical formula was used to model the GoG’s LST. Nearshore wave conditions, crucial for LST estimation, were derived by projecting significant wave hei...

Abstract This study applied ocean models data from Copernicus Marine Environment Monitoring Service (CMEMS) in assessing the impacts of the trends in key ocean parameters on the primary production of the Gulf of Guinea (GoG). Trend analyses, from 1993 to 2020, were done using linear regression and Mann-Kendall significance test methods to ascertain...

In this research, the evaluation of Ghana’s wave energy potential was presented based on the ERA5 monthly averaged data on single levels from 1979 to 2020 from European Centre for Medium-Range Weather Forecast (ECMWF). The data obtained which was the Significant Wave Height and Wave Period were used to calculate the Average Wave Power and Energy. T...

This study assessed the extremes of wave conditions for past (1979–2005) and future (2026–2045 and 2081–2100) time slices in the Gulf of Guinea (GoG). The ensemble produced from eight General Circulation Models under different Representative Concentration Pathway (RCP) emission scenarios (RCP4.5 and RCP8.5) was subjected to linear regression analys...

The focus of this study is the assessment of the past wave conditions in the Gulf of Guinea region of the West African coast to get a better understanding of the trends the waves have been following over the past four decades. The third-generation spectral wave model, WAVEWATCH III (WW3), was used to hindcast the wave climate between 1st January, 1...

Sea surface salinity (SSS) is a key variable for ocean–atmosphere interactions and the water cycle. Due to its climatic importance, increasing efforts have been made for its global in situ observation, and dedicated satellite missions have been launched more recently to allow homogeneous coverage at higher resolution. Cross-shore SSS gradients can...

The analysis of the gradient of Sea Surface Salinity (SSS) in coastal part of the global ocean has been done to see the rate of increase or decrease coastward on a seasonal basis. The coastal ocean was limited to 200km from the nearest coastline to the observation points. An attempt was made to compare results found for In-situ data (TSG) and satel...

This work includes the study and investigation of the surveyed and sampled area, water body off Abereke-Gbabijo coast, to gather useful oceanographic (including bathymetric, Physicochemical and Heavy metals concentration) data through approved sample collections and analyses, parameters measurements and processing and analysis of data to deduce fro...
