| Laboratory-scale studies on the initial weathering of some oils on water by evaporative loss and dissolution have been carried out. Evaporation rate was dependent on the type of oil and was accelerated by increased temperature, number retarded evaporation rate. The order of evaporation rate was Gas Oil >Diesel Oil > Medium fuel Oil. Dissolution rate, which varied with the type of oil, was retarded by salinity but promoted by increased temperature. With the mono-component oils tested, the cyclic, aromatic and iso-characters increased dissolution rate. The order of dissolution rate for the commercial oils was Gas Oil Diesel Oil > Medium Fuel Oil. |

| Continuous monitoring of Sea and Harbour (Lagoon) Surface temperature and salinity at two stations has been carried out from 1978 to 1981. This paper presents the findings for the period and relates it to the prevailing meteorological regimes. The pattern of sea surface temperature at Victoria beach in the study period shows a clearly defined mean maximum temperature of 29.34oC in April, and clearly defined mean minimum temperature of 25.63 in August. Depending on the year, there may be a less clearly defined mean maximum and minimum temperature in October/November and in January respectively. The pattern of surface temperature in the Harbour station is basically similar. The salinity cycle especially in the Harbour was found to be critically... |

| The coastal waters in Nigeria are described in relation to the general morphology, vegetation and beach Type along the 850km coastal. The environmental sensitivity of the fragile Niger delta ecosystem is expressed by the numerous estuaries, rivers, creeks, lacustrine and inshore waters which support freshwater and brackish water mangrove swamps. Ocean resources exploited from the Niger delta and adjacent Continental platform include oil, gas and fishes. The general hydrograph and superfial circulation are described against the background of human activities in coastal settlements and developmental pressures for resource utilisation giving rise to water pollution. Micropollutants identified and measured so far include organic waste, trace heavy metals... |
