with special modes such as hyper spectral imagery. The e2v high-resolution focal plane is a CCD (charged窶田oupled device) imaging sensor. This sensor has five multispectral bands with ranges of 450nm to 900nm. It is an 8192 x 1 pixel device with 12pm square pixels. The sensors on board NigeriaSat-2 are 1. E-OP1 (Pan achromatic and 4 band colour imager) 2. E-OP2 (Wide area coverage imager)
Figure 2: Sediment discharges in the Mississippi Delta (USA) ﾂｩ NASA/ORBIMAGE RESULTS Geology of a region is a major factor that determines the sediment materials transported by rivers and streams after weathering process. A typical example is shown in fig. 4 where the river discharge enters the estuary. Seafloor sediments in many coastal areas show great spatial and temporal variation but the surface sediments give information about the energy of the coastal waters as well as the movement of materials fig. 3 and fig. 5. Result from research indicates that complicated mixing processes occur at the turbidity front where the river discharge enters
