Plastic at the Hadal Depth: The Challenger Deep Sighting and the Broader Deep-Sea Debris Trend

In 2019 Victor Vescovo reached about 10,927 metres in the Challenger Deep and reported seeing something that looked like a plastic bag, but the observation was hedged and not recovered; subsequent analysis notes that a JAMSTEC study had already logged a plastic bag at 10,898 metres, and broader research shows single-use plastic debris is common at hadal depths, making the general claim of plastic in the deep sea well-supported even if the specific bag sighting isn’t definitively confirmed.

Deep Sea Explorer Don Walsh, Pioneer of Ocean Exploration, Passes Away at 92

Don Walsh, a retired Navy captain and deep-sea explorer, has passed away at the age of 92. In 1960, Walsh and Swiss engineer Jacques Piccard became the first to reach the deepest part of the ocean, the Challenger Deep in the Mariana Trench. Descending to a depth of 35,800 feet, they spent 20 minutes on the seafloor, confirming the existence of marine life. Walsh's pioneering spirit and contributions to oceanography will be remembered.

Don Walsh, Pioneer of Deep Sea Exploration, Passes Away at 92

Don Walsh, a Navy officer who reached the deepest point in the ocean, known as the Challenger Deep, in 1960, has died at the age of 92. Alongside Swiss oceanographer Jacques Piccard, Walsh descended nearly 36,000 feet into the Mariana Trench, opening new frontiers in deep-sea marine biology. Their observations of fish, shrimp, and jellyfish at extreme depths provided valuable insights into the range of life that could survive in such conditions. The mission was an audacious stress test for deep-sea exploration, and the success of the Trieste bathyscaph paved the way for future discoveries. Walsh's legacy as a pioneer in oceanography and deep-sea exploration will be remembered.
