He noted that Nigeria must improve the way ocean information is collected, standardised and shared if it hopes to fully harness opportunities within the maritime sector.
According to him, accurate nautical charts and ocean-data products play a vital role in reducing navigational risks, supporting maritime trade, fisheries management and protecting marine ecosystems.
Fadahunsi disclosed that Nigeria would commemorate World Hydrography Day on June 20 in Lagos, in line with the global programme of the International Hydrographic Organisation (IHO).
He explained that this year’s theme was designed to attract a wider audience, including policymakers, industry players, academics and members of the public, rather than being limited to hydrography professionals.
The NHA boss highlighted the growing importance of S-100-based digital hydrographic services, including advanced electronic navigational charts and bathymetric data products, which are becoming global standards for maritime navigation.
He said adopting such technologies would help Nigeria enhance shipping safety, improve trade efficiency and contribute to international efforts aimed at securing sea routes.
As part of the celebration, a plenary session will bring together experts, researchers, regulators, maritime agencies and development partners to discuss ways of improving ocean-data sharing and strengthening maritime governance.
Fadahunsi said the discussions are expected to produce practical recommendations for improving access to ocean information, strengthening cooperation among stakeholders and supporting the sustainable development of the maritime sector.
He added that Nigeria’s participation aligns with the United Nations Sustainable Development Goal 14 on Life Below Water and the UN Decade of Ocean Science for Sustainable Development.
According to him, embracing modern hydrographic standards will position Nigeria as a key contributor to global efforts aimed at improving ocean information systems for safer shipping, stronger coastal communities and environmental protection.
World Hydrography Day is observed annually on June 21 to promote awareness of hydrography and its role in maritime safety, trade and marine conservation.
