SIGNIFICANT OUTCOME: Shelf Programme in West Africa
In 2012, GRID-Arendal completed a major seafloor mapping programme, providing the most comprehensive seafloor
geophysical data set ever collected in the region. Technicians and specialists from seven West African countries
(Cape Verde, Gambia, Guinea, Guinea-Bissau, Mauritania, Senegal and Sierra Leone) participated in regular capacity-
building workshops held at GRID-Arendal during 13-2012, where interpretation and analysis of the marine geophysical
data collected in the west African region was carried out. These workshops have not only built technical capacity for
the participants, but have also built bridges and professional networks among African experts, fostering regional
collaboration, sharing of information and dialogue.
