Speleology to cave science in the world. The growth of speleology is directly linked with that of the sport of caving, both because of the stimulation of public interest and awareness, and the fact that most speleological field-work has been conducted by sport cavers. The creation of an accurate, detailed map is one of the most common technical activities undertaken within a cave. Cave maps, called "surveys", can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for further scientific study, and assist visitors with route-finding.

European and American voyages of scientific exploration were instigated by government. In the late 19th century, when this phase of science was drawing to a close, it became possible to earn a living as a professional scientist although photography was beginning to replace the illustrators. The exploratory sailing ship had gradually evolved into the modern research vessels. From now on maritime research in new European colonies in America, Africa, Australia, India and elsewhere, would be carried out by researchers within the occupied territories themselves. This compendium of voyages of scientific exploration provides an overview of maritime scientific research carried out at the time of the Enlightenment in
