1.8.3 Field Observations<br />

Field assessments were undertaken between April and June 2015. Field visits mainly covered<br />

marine environment, hydrology and areas on land where boreholes are to be drilled. In addition,<br />

stakeholder consultations were carried out with relevant agencies, specifically for this EIA.<br />

1.8.3.1 Oceanography<br />

Bathymetric data was collected by attaching an echo sounder system with a small motorized<br />

vessel and traversing the area following depth sounding principle. Secondary bathymetric data<br />

available on charts were also collected and reviewed.<br />

Currents were measures using drogue method. About 3 measurements were undertaken from<br />

every site and an average value is determined. Current measurements at the surface of lagoon<br />

and open sea were also measured using an AQUAlogger 520 current meter. The Wave/Current<br />

measurement is divided into six layers for assessment purposes. They are the surface, 0.2H,<br />

0.4H, 0.6H, 0.8H and bottom (see Figure 1.2).<br />
