National Centre For Marine Geosciences

Primary tabs

The National Centre for marine Geosciences, located in Yenagoa, is mandated to collect and collate geo-scientific data and information from Nigeria’s coastal and offshore environments central to reconstruction of their geological evolution, mineral resources discoveries and exploitation, geohazard mitigation, and sustainable development.

In pursuit of this mandate, the Centre creates a data bank and body of knowledge where concerns and challenges of investors, investigators and all other stakeholders interested in geo-scientific evolution, exploitation, development, vulnerability and management of Nigeria’s coastal and offshore environments are creditably catered for.

Capacity-building and research efforts of the Centre have been recently welcomed by Niger Delta University, University of Port Harcourt, Federal University Otuoke, AkwaIbom State University, Federal University of Technology Akure, and the International Council of Science Union (Regional Office for Africa), South Africa.

CARDINAL FUNCTIONS:

These include the following:

  • Origin and evolution of coastal and offshore environments
  • Sedimentary characteristics and dynamics of the seabed, coastline and coastal morphologies
  • Geochemical composition and geophysical structure of the coastal and offshore environments
  • Mineral occurrence and distribution in the coastal and offshore environments
  • Potentials and prospects of non-mineral energy resources exploitation in the coastal and offshore environments
  • Vulnerability of the coastal and offshore environments to geohazards and human activities
  • Possible effects of eustastic and tectonic processes on the coastal and offshore environments

Sub-sampling beach sediments for geochemical assessment calls for utmost care to avoid contamination as demonstrated by NCMG personnel at the backshore of Seme Beach. Note the high level of anthropogenic litter (mostly water sachet) at the beach backshore and foreshore

 


Depth sounding of water body is a major task of NCMG geochemical mapping
