From page 146...
... Underwater vehicles and related in situ sensors will advance significantly in the next 16 years in terms of operating range, endurance, and in the types of measurements they can make. By vehicles, I am referring to powered autonomous underwater vehicles, remotely operated vehicles, gliders, and floats.

From page 147...
... The change from laboratory analysis to in situ sensing not only dramatically lowers the cost per measurement, it also enables vastly improved spatial coverage as well as long-term time series observations that conventional sampling and laboratory analysis cannot possibly accommodate. AUVs with such capabilities will enable fundamentally new operational paradigms.

From page 148...
... Remotely operated vehicles are likely to evolve significantly in the near future as well. Taking advantage of many AUV technologies, selfpowered remotely operated vehicles communicating with light optical fiber tethers, acoustic communications, or optical links will enable direct human control or at least human supervision without the heavy cables required to transmit power.

From page 149...
... Undoubtedly laboratory instrumentation will continue to evolve and the resulting capabilities will always exceed those of in situ sensors. For example, in situ mass spectrometers will enable many new types of investigations; but they will not have sufficient performance to replace accelerator mass spectrometer facilities to determine the ventilation age of seawater.
