Many of the studies we have included in our database for this revision pertain to the design of bio-inspired vehicles and manipulators. The reason is that the excellent document “Recent progress on underwater soft robots: Adhesion, grabbing, actuating, and sensing” by Yeming Zhang, Demin Kong, Yan Shi, Maolin Cai, Qihui Yu, Shuping Li, Kai Wang, and Chuangchuang Liu, which was highlighted in the previous revision, opens to new concepts to be documented.
This section relates to underwater archaeology documents, museums and all activities that promote the history of diving and navigation. Our database contains about 130 papers by real archaeologists, UNESCO reports and regulations concerning these activities, which should be in accordance with the "United Nations Convention on the Parts of the Sea Under the Authority of States". There is also a list of downloadable museums. While archaeologists have often used the services of recreational divers for years, the exploration of deep wreck sites inaccessible to such divers may require them to use the services of professional diving and ROV teams, applying the procedures in force in the offshore industry. Please note that nine new documents have been added to our database. Click on the button below to view the list.

In this publication, Jean-Pierre Imbert explains the history and justification of the Comex treatment table Cx 30, which represents a significant advancement in the field of hyperbaric medicine. This procedure is commonly used in many countries and recommended by various organizations, including the Diving Medical Advisory Committee (DMAC). Despite this, it is still not widely used in certain regions. Therefore, I hope this presentation will change the minds of those who have not yet been convinced by its efficacy and make them embrace it. Jean-Pierre Imbert started his exceptional career in 1975 with a master's degree in biomedical engineering, obtained at the Institute for Environmental Medicine in Philadelphia where he studied isobaric counter diffusion under the direction of Dr Christian J. Lambertsen. From 1975 to 1995, he was part of the Comex research & development team which led all the deep dives programs including the CORAZ animal experimental program to 1000 msw, the manned experimental and operational deep dives, i.e., JANUS IV 450 msw, DRET 450 msw, JASON experimental argon saturation, and the Hydra program using the hydrogen-helium-oxygen breathing mixture that culminated in two world records: Hydra 8, at sea, and Hydra 10 onshore, with 534 msw and 701 msw depth, respectively. Being the Comex Diving Manager from 1982 to 1995, Jean-Pierre Imbert designed the Comex diving procedures, particularly the 1986 and 1994 revisions of the Comex diving manuals and safety management system. He designed the French government MT92 diving tables which have become an international reference, and the deep diving operations procedures that have been published by the Brazilian authorities as NORMAM-15/DPC. Jean-Pierre Imbert had major participation in the Norwegian Deepex I 300 msw and II 450 msw projects at the Norwegian Underwater Institute, in the 350 msw offshore pipeline repair, and the 350 msw NorskHydro Oseberg project. He also designed procedures for major tunnelling interventions accomplished in Barcelona, Hong Kong, and Singapore, and is the author of diving manuals for diving companies. Jean-Pierre Imbert keeps leading research & development programs and publishing landmark scientific papers. This article was first printed in the DAN Recompression Chamber Network newsletter (https://dan.org). It is published with the organization's authorization. Click on the button below to open it.
