New english language sources for ABISMO wiki artlcle

[edit]

New ref MTS-1: [1]

New rdf MTS-2: [2]

Background from MTS-2:

"The ROV Kaiko which JAMSTEC developed ... had achieved various milestones such as obtaining sediment samples from the Challenger Deep... However, on May 29, 2003, the vehicle portion of the launcher/vehicle complex Kaiko was lost because of snapping of the secondary cable linking the launcher with the vehicle after completion of research in the Nankai Trough off Japan.

"After this incident, JAMSTEC developed the ROV Kaiko 7000, composed of the original launcher from the ROV Kaiko and a newly developed 7,000 m class vehicle. This system ... is not able to reach full ocean depth.

"In 2005, we thus started the development of a new full depth ROV, ABISMO (Automatic Bottom Sampling and Inspection Mobile), with the capability to sample both sediments and water. The concept behind this system was reported in 2002 (Yoshida et.al. 2006 -- [3]

"In 2007 the first sea trials were carried out. In June 2008, we successfully sampled sediment and water from the Mariana Trench and completed by-and-large the development of the ABISMO system.

"Since this, Andy Bowen (Bowen et.al., 2009) at WHOI successfully completed the first dive of the Nereus new concept Hybrid ROV to a depth of 10,903 m on May 31, 2009. The major difference in performance between the ABISMO and the Nereus is their sampling capability. The ABISMO is connected to its mother ship via a thick cable and can therefor retrieve a large amount of sample material with long cor samples. The vehicle maneuverability is limited by the cable.

"The Nereus is highly maneuverable and can retrieve only small amounts of sample sediment because it is connected to the surface solely through a thin fiber-optic cable. Both vehicles have full depth dive capability, but their sampling applications do not overlap to any great degree.

Fig 1 of MTS-2 should be shown in wiki article for ABISMO -- I definately don't know how to do thatGwyncann (talk) 19:49, 15 December 2019 (UTC)[reply]

Factoids for description of ABISMO program from MTS-2: "The total budget allocated for the development of ABISMO was only 2 million dollars. We therefore used/re-used the Kaiko's cable system and power supply as a part of the ABISMO ship-side system. The ABISMO system is mounted on the dedicated mothership RV Kairei. {The 3070-kg launcher is the legacy launcher vehicle from the ROV Kaiko and is rated to 11,000 meters} The 327-kg ABISMO vehicle cruises below the launcher freely within the reach of the 160-m-long cable to survey the sea floor with a TV camera. {weights above are weights in air -- much less in water -- see ref MTS-2 Gwyncann (talk) 19:49, 15 December 2019 (UTC))[reply]

Fig 6 MTS-2 shows a cut-away drawing of the ABISMO vehicle, including the crawler tracks. And table 2 on p. 91 gives specifications of the vehicle including the scientific tools attached.

Page 92 of MTS-2 includes a complete description of the ABISMO vehicle including camera, lights, NavAids and transponder. These specification could be developed into a sidebar for the wiki article showing key elements of its size and capabilitiesGwyncann (talk) 19:49, 15 December 2019 (UTC)[reply]

On page 94 of MTS-2 is found a list of the first 14 dives of the ABISMO system -- from #1 Jan 5 2007 to dive 14 Jun 4, 2008. Dives 11-13 were to FOD in the Mariana trench on June 1,2,3 2008. "Unfortunately, we were unable to dive to the sea floor because the legacy primary cable of the Kaiko system was a little bit short. The 2-m long gravity core sampler was dropped in free fall, and sediment samples of 1.6m length were obtained. Twelve bottles of water samples were also obtained at various depths... The small full depth transponder ...was tested successfully...

Page 95 of MTS2: "The ABISMO system was mainly designed to make pre-site surveys of the sea floor and to sample mud and water for biological research. The total development cost was only $2 million because the legacy primary cable-winch system of the Kaiko was reused. The development of the basic ABISMO system has mostly been completed, but further work on operations and to develop additional functions is still necessary to realize its full potential. One goal is to make a new cable to enable ABISMO to reach the bottom of the Challenger Deep."

For purposes of a complete history of the ABISMO program, I will have to research its history after 2009. I earlier wrote that it was lost on dive #21 -- that was wrong and conflated a later system called the UROV11K, which was lost in the Challenger Deep in 2017 from the RV Kairei.

HELP HELP HELP -- I could write up a completely new wiki article integrating the above info, but I seek consensus before I work on this. Alternatively, we could remove current data selectively and add the above as appropriate to slowly modify the existing article to reflect this info. In either case, I think the present article needs to be almost completely erased in order to provide a coherent narrative showing the above.Gwyncann (talk) 19:49, 15 December 2019 (UTC)[reply]
