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. Caves provide
Exploration of the Pacific Cook set a high standard of scientific exploration, showed that there was no large land mass in the southern ocean, mapped the two largest island groups in the Pacific and by following the east coast of Australia and the west coast of North America closed the last gaps in European knowledge of the Pacific coasts. After Cook everything was detail. Cook's rivals and successors: Several governments sponsored Pacific expeditions, often in rivalry or emulation of Captain Cook.
