Secrets of the Deep: Defining Privacy Underwater

The drones are coming, But not just to your neighborhood skies – to the world’s oceans. From recreational robots designed to autonomously follow divers and record video of them to low-cost, remotely operated submersibles that put ocean exploration in the hands of the general public to sophisticated military submersibles able to autonomously gather intelligence throughout the oceans, the underwater drone market is exploding. But unlike on land, this explosion has not been accompanied by similar discussion of privacy concerns. Instead, the ocean’s rapid shift away from an inaccessible operational sanctuary is one that is happening largely silently. And it is one that is happening in an economically critical environment with far fewer legal protections in place than on land. This Article examines this monumental shift, exploring for the first time privacy and trade secret protections from underwater surveillance. I argue that privacy protections are already unconstitutionally eroded underwater and must be strengthened in the face of widespread drone use

HUGO:The Hawaii Undersea Geo-Observatory

The Hawaii Undersea Geo-Observatory, HUGO, was installed with the intent of supplying infrastructure for researchers interested in studies of undersea volcanism and associated phenomena at Loihi, the newest volcano of the Hawaiian chain. Much like an astronomical observatory, HUGO is a facility where scientists can perform experiments while sharing resources with others. The main components of HUGO are the shore station, supplying power to the observatory and recording data; the main cable-an electro-optical cable connecting the shore station to the summit of Loihi; the Junction box-the power distribution and data collection center on Loihi; multiplexing (mux) nodes-secondary distribution points; and experiments supplied by scientists. HUGO can potentially supply electrical power, command capability and real-time data service to more than 100 instruments connected and removed on the ocean floor by submersible or ROV. HUGO was installed on October 11, 1997, but the main cable developed an electrical short circuit to sea water on April 26, 1998, and a new cable must be obtained and installed before routine operations can continue. Despite the failure, several important tasks have been accomplished, including: 1) the successful small-ship lay of the 47-km electro-optical cable from the Island of Hawaii to the summit of Loihi submarine volcano; 2) installation and servicing of the Junction box; 3) successful operation of electro-optical connectors on the ocean floor by submersible; 4) installation and removal of experiments on the ocean floor; 5) transmission of power and commands from shore to experiments installed at HUGO; 6) transmission of high-rate, high-fidelity data from the summit of Loihi to shore in real time; and 7) recording of volcanic, earthquake, biological, ocean wave and ship noises for a period of three months. This paper provides a general description of the HUGO system and its history of operation

The Vulnerability of Subsea Infrastructure to Underwater Attack: Legal Shortcomings and the Way Forward

This Article explores the vulnerability of submarine pipelines and cables to underwater subterfuge beyond territorial waters, particularly with regards to the emerging threat posed by unmanned vehicles in executing such mal intent. Next, it describes the legal status of this critical infrastructure before identifying shortcomings in legal protection from underwater attack. Finally, potential solutions are offered for the way forward

The feasibility of obstacle awareness forwarding scheme in a visible light communication vehicular network

A vehicular-to-vehicular (V2V) communication is a part of a vehicular ad-hoc network (VANET) that emerges recently due to the heavy traffic environment. V2V is a frequently changing network since it implements vehicles as mobile nodes. The challenges in implementing V2V are the relatively short duration of possible communication and the uneven city environment caused by high rise buildings or other objects that distract the signal transmission. The limited transmitting duration between vehicles requires efficient coordination and communication. This work focuses on the utility of visible light communication in vehicular network (VLC-VN) in data transmitting and the obstacle awareness in the forwarding scheme based on our knowledge in previous researches. The result of evaluating the feasibility of VLC-VN forwarding in a freeway environment the transmission delay is lower than 1 second in 500 byte data transmission, however it reaches to only about 4% in throughput as a drawback
