Cut down on noise fatigue, increase your ease of communication and never feel alone again.

A complete system typically includes The “SOLO” Dual-Radio

Headset Station, your choice of an over-the-head or behind-the- head Marine Headset and a Push-to-Talk “Body” Switch. For more information about this system and many others contact David

Chikyu:

Deep Drilling Vessel

Chikyu is a state-of-the-art scientific drilling vessel that is designed to drill to 7,000 m below the seabed at approximatedly 2,500 m water depth. Built at Mitsubishi Heavy

Industries for more than $500 million,

Chikyu's first scheduled assignment will be in the Nankai Trough, a Pacific Ocean zone between two tectonic plates that have pro- duced powerful earthquakes through Japan's history. When it begins service as scheduled in 2007, it could be the first vessel to drill to the earth's mantle, and is intended to play a major role in the Japanese effort to protect the country from the devastation associated with earthquakes. It is equipped with the

Riser drilling system that has achieved suc- cess in oceanic oil drilling, and is designed to shield the vessel against eruptions of methane gas and pressurized fluids, while allowing for the retrieval of valuable core samples. In addition, the vessel's Dynamic

Positioning System (DPS) is designed to keep the vessel on position, counteracting the drift from wind, waves and sea current.

The 210 m, 57,000 ton ship can efficiently remain on station using its GPS and six azimuth thrusters. There are four integrated research areas on the vessel that house mul- tiple research facilities for physical, scientif- ic, and biological analysis by using the sam- pled core (cylindrical sediment and/or rock sample) and the drilled hole.

The main objectives of D/V CHIKYU is to drill through the earth's crust and reach the man- tle, where no one has ever explored before, to open the door for direct understanding the relationship between global-scale envi- ronmental change and mantle processes.

The key is the ship's mammoth drill, which operators say is capable of boring nearly 4.5 miles into the ocean floor, far deeper than the 2,111-m hole achieved by the U.S.'s drilling vessel Joides Resolution.
