With a maritime domain covering approximately 1.4 million square kilometers, Seychelles is fundamentally an ocean state. To better understand, manage, and protect this vast aquatic frontier, the national Cabinet has officially approved the establishment of the Seychelles Hydrographic Office within the Seychelles Maritime Safety Authority (SMSA).
This strategic move creates a dedicated national framework to coordinate marine data, transforming how the island nation navigates its future in the Blue Economy.
Mapping the Ocean Frontier
In a recent press briefing, SMSA Chief Executive Officer Captain Daniel Adam explained that hydrography does for the ocean what topography does for the land. While the islands appeared on early navigational charts centuries ago—with the first recorded surveys dating back to 1742—mapping an ocean territory of this scale remains a monumental task.
In 2024, a major survey completed in partnership with the UK Hydrographic Office generated four terabytes of data, mapping roughly 650 square kilometers around Mahé, Praslin, and La Digue. Despite this significant achievement, the area surveyed represents less than 0.05% of the nation’s total waters.
The primary mandate of the newly established Seychelles Hydrographic Office is to bridge this massive data gap. It will systematically coordinate and preserve hydrographic information as a sovereign national asset, making it accessible to agencies requiring accurate seabed depths and marine topography.
Beyond Navigation: Empowering the Blue Economy

For readers following our Business coverage on the Afrikeye homepage, this development is about much more than producing updated navigational charts for ships. Modern hydrography is the backbone of sustainable marine development.
When layered with environmental and geospatial data, hydrographic insights support marine spatial planning, sustainable fisheries management, and climate change adaptation. It also strengthens search and rescue operations, ensuring safer maritime routes for local industries and international visitors exploring the islands via platforms like Afrikeye Travel.
A Continuous Technological Evolution
The Seychelles Hydrographic Office will not rely solely on traditional survey vessels. To accelerate coverage, the agency plans to integrate emerging technologies, including satellite-derived bathymetry, remote sensing, and crowd-sourced data.
Ultimately, hydrography is not a short-term project with a fixed end date. As new data and technologies emerge, the Seychelles Hydrographic Office will serve as a permanent, evolving institution. By transforming raw ocean data into actionable knowledge, it ensures that Seychelles can safely navigate its maritime ambitions and sustainably manage its marine resources for generations to come.
