A low-cost, miniature CTD for animal-borne ocean measurements

摘要

The study of fine-scale linkages between animal behavior and the physical microstructure of the marine habitat is essential for understanding the ecology of many marine animals. Animal-borne salinity data has the potential to define the importance of physical water mass features to the ecology of marine animals. Recently CTD (conductivity, temperature and depth) data loggers mounted on large marine mammals (pinnipeds and cetaceans) have been able to capture direct qualitative information on the physical microstructure of the foraging environment and microhabitat.
