The Navy Experimental Diving Unit tested the Deep Sea Expeditionary with No Decompression (DSEND) Suit underwater last February.
The Atmospheric Diving Suit (ADS) used by the Navy at the moment is cumbersome, unmaneuverable, and requires relatively large sea craft for deployment. With this new project, it will be improved in a number of ways, including the rotary joint design that it now uses.
The Satellite sank on 21 June 1879, according to the historical society, either as a consequence of a technical issue or because the boat collided with a floating log. The ship capsized, but no one perished.
In the summer of 2022, the society worked with Josh Gates of the Discovery Channel's Expedition Unknown to produce a show about two French minesweepers that vanished on their maiden voyage in 1918.
In 2019, paleontologist Karma Nanglu from Harvard University received a finger-sized fossil. The specimen had originated from a fossil-rich stratum of Cambrian limestone in western Utah, and had been kept in a drawer at a Salt Lake City museum for years.
Upon hearing that there could be a very old tunicate, Nanglu expressed excitement interlaced with caution: "That's a group for which there is essentially no fossil record for the entire 500 million years of recorded history."
For more than two years, researchers on board the French expedition ship Tara sailed through the Pacific, stopping at almost 100 coral reefs to take thousands of water and coral samples. The expedition ended in 2018, and the analysis of the massive amount of data collected has taken five years.
Now, the initial results of the data analysis have been published. The findings should help us to better understand the living conditions of corals, to check their health status and to open up new possibilities for nature conservation.
