In the age of yore, when Britannica ruled the globe and the sun never set in the British Empire, several factors contributed towards the Royal Navy’s global sea dominance. While maritime aspirations owing to unfavourable conditions and lack of resources at home was a major reason for the outwards pivot, the hydrographic prowess demonstrated by able Naval surveyors provided the necessary means to create sea-based ‘in-roads’ into erstwhile unfamiliar and uncharted waters.
In modern times, the field of hydrography has evolved from being a pre-condition for expeditionary and exploratory operations overseas to the benign role of assuring global maritime safety with major hydrographic players freely sharing data and products with each other under the overarching umbrella of the International Hydrographic Organisation (IHO). This noble aim assumes significance for smaller littoral countries, who do not possess the necessary hydrographic resources, which are technically intensive and, in turn, highly expensive, in charting safe navigable passages for maritime trade that are often hindered by archipelagic features and underwater obstructions.
Within the Indian Ocean Rim, several littorals regularly seek hydrographic assistance from capable Navies such as the Royal Navy, United States Navy or the Indian Navy. As they are committed to ensuring the safety of the global commons, these requests are usually actioned upon, albeit at a substantial cost to the service provider government. As an example, a study conducted by the IHO for a hydrographic survey off Vanuatu, a small archipelagic nation located in the South Pacific, placed the cost of a basic hydrographic survey, excluding the price of publishing electronic and paper charts, to a whooping USD 383 Mn in 2013.
