Evaluation of some of the Metal Levels at Different Depths from Gulf of Guinea Offshore Location

Study area is in the Nigeria continental shelf of the Atlantic Ocean, located within seawater depths of 20 – 25 m and geographic X and Y coordinates 337896 – 356905 and 469773 – 482786, offshore Nigeria respectively. Test was conducted to evaluate some of the metal levels at different depths from Gulf of Guinea offshore location. Samples were collected from the depth of 5m, 10m, 15m and 20m respectively and tests were conducted over a one year period on a quarterly basis. Test result indicated that mean value over the period for the metals tested was: Mg(1160mg/l), K(369mg/l), Na(8062mg/l), Ca(380mg/l), Al(<1.0mg/l), Fe(0.05mg/l), Cu(<0.05mg/l), Mn(<0.10mg/l), Zn(<0.05mg/l), Ba(<0.03mg/l), Si(<0.01mg/l), Sr(0.569mg/l), Li(0.559mg/l). This project therefore will help to provide a base-line data on the metal constituents of the Gulf of Guinea offshore location, thereby helping framework for environmental protection for offshore oil and gas activities in the Gulf of Guinea @ JASEM
