Abstract
Studies on effects of wind speed and direction on ocean wave along Ibeno Atlantic ocean, south-south, Nigeria were conducted between May – October, 2016 with the aim of understanding the impact of wind speed on ocean wave along the coastline. Wind speed and wave height were measured bimonthly during spring and neap tidal phases in two stations along the coastline using standard procedure. The results analysis provides an insight to the direction of the prevailing wind on the coastline which was mostly from the North-East direction. The maximum wind speed value was observed to be 4.5 m/s in the month of October during spring tidal phase and the minimum value recorded was 1.0 m/s in the month of May during spring tidal phase and also in the months of June and July during neap tidal phase. The maximum and minimum wave height recorded was 78 cm (0.78m) in the month of August during spring tidal phase and 12 cm (0.12m) in the month of May during neap tidal phase respectively. There was a transition in stratification between high and low wind speed as observed during the study. Wind speed has a direct impact on the incoming waves from offshore as it was observed that an increase in wind speed also brings about a corresponding increase in wave breaker height. As large water mass is transported offshore, it is being interrupted by wind. As the wind blew over the sea surface, the large water mass was affected, resulting in high wave magnitude and height, which travel several kilometers before breaking at the shoaling zone. Based on findings it was concluded that wind speed and direction has a direct impact on ocean wave along the study area.
