Depiction of Marine Life Observation Technologies (IMAGE)
Caption
Scientists explore on and beneath polar ice. Their aircraft remotely sense animals through properties of scattered light. Marine animals themselves carry tags that store records of their travels and dives and communicate with satellites. Fish carry tags that revealed their migration past acoustic listening lines. Sounds that echoed back to ships portray schools of fish assembling, swimming, and commuting up and down. Standardized frames and structures dropped near shores and on reefs provide information for comparing diversity and abundance. Manned and unmanned undersea vehicles plus divers photograph sea floors and cliffs. Deep submersibles sniff and videotape smoking seafloor vents. And nets and dredges catch specimens, shallow and deep, for closest study.
