A well-knowned project was developed by James Cameron and the National Geographic – the Deepsea Challenger. The manned lander was used in 2012 to go to the deepest place on Earth – the Marianas Trench. One of the most important vehicles in the oceanographic community is the ALVIN deep submergence vehicle (DSV) from WHOI.

The French IFREMER institute has the NAUTILE manned submersible capable of 6000 meters depths. The Russian Mir II, battery powered and 3 person submersible, is also capable of achieving 6000 meters depths. This deep diving capabilities allows this vehicles to reach approximately 98% of the ocean floor. B. Remotely Operated Vehicle The biggest robotic tool for deep sea operations are the ROVs.

  • The Development of Autonomous Underwater Vehicles (AUV); a Brief Summary
    The Development of Autonomous Underwater Vehicles (AUV); A Brief Summary D. Richard Blidberg, (blidberg@ausi,org) Autonomous Undersea Systems Institute, Lee New Hampshire, USA Introduction The concept of a submersible vehicle is not a new idea. The first American submarine was called “Turtle.” It was built at Saybrook, Connecticut in 1775 by David Bushnell and his brother, Ezra. The Turtle was a little egg-shaped wooden submarine held together by iron straps. Turtle bobbed like a cork in rough surface winds and seas even though she was lead weighted at the bottom. In this hand and foot-operated contraption, one person could descend by operating a valve to admit water into the ballast tank and ascend with the use of pumps to eject the water. Two flap-type air vents at the top opened when the hatch was clear of water and closed when it was as not. The air supply lasted only 30 minutes. The Turtle's first engagement, which took place in New York Harbor in 1776, was also the first naval battle in history involving a submarine. [Pararas] In November of 1879, the Reverend George W. Garrett designed, what was considered by some to be the world's first practical powered submarine, the “Resurgam.” It was built at the Brittannia Engine Works and Foundry of J. B. Cochran in Birkenhead, England and was powered by a Lamm 'fireless' steam engine, and could travel for some ten hours on power stored in an insulated tank. After these historic underwater vehicles, there have been many more submersibles developed and used operationally for a number of different tasks.

    MARINE ECOLOGY PROGRESS SERIES Published September 17 Mar Ecol Prog Ser Benthic in situ respiration in the upwelling area off central Chile Ronnie N~hrGlud*, Jens Kristian Gundersen*', Ola Holby8** Max Planck Institute for Marine Microbiology. Microsensor Research Group, Celsiusstraße 1,28359 Bremen, Germany ABSTRACT. Benthic O2 uptake rates and O2 microprofiles were measured in the upwelling area off central Chile. Measurements were performed both in situ and in the laboratory on recovered sediment cores. Comparison between the 2 data sets confirmed retrieval and handling artifacts inferred from previous studies. Onboard measurements indicated that the effects were mainly associated with core warming during recovery. Fauna mediated O2 uptake was significant even at abyssal depths and gen- erally in situ O2uptake rates were higher and showed stronger attenuation with water depth than pre- vious measurements performed in the NE Pacific. However, O2uptake rates and O2penetration depths were very sirnilar to measurements performed in the SE Atlantic, and the compiled data sets were approxirnated by simple exponential equations relating the measurements to water depth. By compar- ing our total O2 in situ uptake rates to simultaneous measurements of primary production (PP) and new production (NP) of the overlying water column, it was calculated that the benthic mineralization accounted for 13 to 66% of the PP and for 28 to 92% of the NP at water depths shallower than 1000 m. At water depths from 1000 to 4000 m, the benthic rnineralization equaled 2 to 11 % of the PP and 22 to 38% of the NP. The benthic mineralization thereby accounted for a significant turnover of organic material even at the abyssal stations.

Received: 28 April 2019; Accepted: 5 June 2019; Published: 10 June 2019 Abstract: Marine environments are currently subject to strong ecological pressure due to local and global anthropic stressors, such as pollutants and atmospheric inputs, which also cause ocean acidification and warming. These strains can result in biogeochemical cycle variations, environmental pollution, and changes in benthic-pelagic coupling processes. Two new devices, the Amerigo Lander and the Automatic Benthic Chamber (CBA), have been developed to measure the fluxes of dissolved chemical species between sediment and the water column, to assess the biogeochemical cycle and benthic-pelagic coupling alterations due to human activities.
