This diverse group of explorers included a scientific complement of ichthyologists, geneticists, reproductive biologists, oceanographers, and a hydrographer, along with educators, program managers, two journalists, several graduate students, and even a scientific illustrator. Because of their isolation, seamounts act as an oasis in an otherwise barren landscape, and are known to harbor species found nowhere else. Since most seamounts in the New England chain have never been explored scientifically, there was great potential for new discoveries during this expedition. The primary objectives were to map the distribution of octocorals and assess the overall diversity of seamount organisms; determine whether New England seamount octocorals are genetically distinct; examine the reproductive state and larval strategies of seamount octocorals; assess the physical impact of bottom trawling on octocoral communities and seamount biodiversity; and acquire multibeam data to produce high resolution maps of the regions studied.

R/V Atlantis Atlantis 2012-05-15 creation Atlantis (AT) The research vessel (R/V) Atlantis is owned by the U.S. Navy and operated by WHOI for the oceanographic community. It is one of the most sophisticated research vessels afloat, and it is specifically outfitted for launching and servicing the Alvin human occupied submersible. Delivered to Woods Hole in April 1997, Atlantis was built with six science labs and storage spaces, precision navigation systems, seafloor mapping sonar, and satellite communications. The ship's three winches, three cranes, machine shop, and specialized hangars were specifically designed to support Alvin and other vehicles of the National Deep Submergence Facility.

Kongsberg EM122 Multibeam Echosounder EM122 Kongsberg Maritime http://www.km.kongsberg.com/ks/web/nokbg0240.nsf/AllWeb/01FB0F22974EA50FC125715E002B2143?OpenDocument Kongsberg EM122 information Information on the Kongsberg EM122 multibeam sonar system information resourceProvider Kongsberg EM122 Multibeam Echosounder EM 122 multibeam echosounder is a high performance echosounder for deep water mapping with up to 288 simultaneous beams. The EM 122 is designed to perform seabed mapping to full ocean depth with an unsurpassed resolution, coverage and accuracy. The system is cost effective, reliable, and easily operated. The design of the EM 122 is based on more than 50 years of hydrographic experience with echo sounders, sonars and underwater positioning for civilian and military use. It is the latest model in a series of deep sea multibeam echo sounders started with the EM 12 in 1990 and followed by the EM 121 and the EM 120, of which about 40 systems are operational. It uses the same transducers as in the EM 120 but with new electronics and software. Compared with the EM 120 the EM 122 has up to four times the resolution in terms of sounding density through inclusion of multiping capability and more than twice the number of detections per swath. High density signal processing is a major improvement, to keep the acoustic footprint size small even for the outer beams in the swath. In typical ocean depths a sounding spacing of about 50 m across and along is achievable. The achievable swath width of the EM 122 is in the order of 30,000 m, or about 25% more than possible with the EM 120. This is obtained by using long FM chirps which gains about 15 dB in signal to noise ratio compared to CW pulses. The EM 122 is a complete system. All necessary sensor interfaces, data displays for quality control and sensor calibration, seabed visualization, and data logging are a standard part of the system, as is integrated seabed acoustical imaging capability (side scan). Including a higher frequency multibeam echo sounder such as EM 710 with the EM 122 system can give a total system solution meeting the strictest IHO requirements for all water depths. As proven with the EM 120, an accuracy of better than 0.2% of depth in deep waters is readily achievable with the EM 122.

Teledyne RDI's vessel-mounted Ocean Surveyor family of ADCPs continues to raise the bar, collecting detailed maps of the distribution of water currents and suspended materials through the water column and along the ship's path - at depths and resolutions previously considered unattainable. In real time, the ADCP is also used to aid in situ decision-making, to adapt field operations, and to understand current regime characteristics.
