Supporting the use of AUVs in the search for submerged debris from the

Space Shuttle Columbia in 2003 was one such example. In addition, navi- gating ROVs over the RMS Titanic to bring live high definition footage to living rooms in 2004 and being an honorary plankholder in the NOAA

Ship Okeanos Explorer are some of my favorite memories.

In your opinion, what has been the biggest Enabling Technologies that has advanced subsea vehicles in the last decade?

Kelly, Bluefin Being such a rapidly maturing industry, there are several technologies that have enabled growth opportunities for AUVs.

There are two that stand out. First, the size of sensors and electronics has been shrinking. Companies, like

Bluefin, can now integrate them into

AUVs allowing the technology to address new applications. Second, low-cost data processing has led autonomy to function in real time.

This has allowed us to develop new

AUV behaviors and advance multi- platform operations.

Anderson, OceanServer System developers addressing Subsea chal- lenges have benefitted from advances in a wide variety of technologies, justified or funded by main- stream commercial and military market requirements. CPUs with lower power consumption and run- ning dependable embedded operating systems, with high-capacity memory (often solid-state these days) provide cost-effective processing power and a common interface language for sen- sor drivers. Subsea device developers benefit from a rich selection of sen- sors, navigational aids, and commu- nications devices that can be easily integrated into systems-level products targeted at the relatively niche appli- cations in the subsea environment.

Increased bandwidth has significantly increased underwater images resolu- tion; Power and control systems have improved to meet the demands for operating in stronger currents; and

Digital interface systems have enabled the integration of additional sensors and options.

Heinz, iRobot Designs are more flexible and reliable, and are now proving their viability and cost effec- tiveness beyond the early adopters in the ocean sciences and military.

Future improvements in sensor pack- aging, power efficiency and mobility will accelerate this even further.

Autonomy has also improved signifi- cantly with the advent of smaller and faster processors and better program- ming environments, enabling vehicles to perform more missions with less interaction. That is ultimately how
