THE FIVE DEEP EXPEDITION

Introduction

The “FIVE DEEP EXPEDITION” is the world’s first successful manned expedition to the deepest point in each of the five oceans, and the ultimate validation of a unique deep-sea, manned research submersible. The Five Deeps Expedition’s primary objective was to dive to the deepest point in each of the five oceans.

Expedition Overview

The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench/Factorian Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep (Maraina Trench in the Pacific and Molloy Deep in the Arctic.

  • The expedition covered 47,000 nautical miles / 87,000 km in 10 months
  • The submersible Limiting Factor completed 39 dives
  • Around 50 scientific lander deployments were undertaken alongside the submersible dives
  • No human had previously ever been to the bottom of the Java, Puerto Rico* or South Sandwich trenches
  • No one had ever been to the bottom of Molloy Deep
  • No manned submersible had ever been to Challenger Deep more than once
  • No person had ever been to the summit of Mount Everest and also been to the bottom of the ocean at Challenger Deep, which occurred on this expedition.
  • Java Trench is the deepest point in Indian Ocean. There were competing claims for the deepest point in Indian Ocean. This was between Java Trench off coast of Indonesia and Fracture Zone to the Southwest of Australia. Java Trench turned out to be the winner.
  • The second deepest trench in the world is the Horizon Deep in the Tonga Trench. This is after the Challenger Deep located in Mariana Trench.
  • The expedition has found that some major animals can survive in great depths. Jelly fish at 10,000 metres; Squid at 6,500 metres; Octopus at 2,000 metres
  • Though some of the above findings were already made, the expedition confirmed them, found new lives, corrected erratic data and also updated some
  • The Five Deeps Expedition has provided data on the deepest points of five oceans in the world. They are the Pacific, Atlantic, Indian, Arctic and the Southern Oceans.

Significance of Five Deeps Expedition

Such projects are important as 80% of world oceans are still unexplored. And countries are aggressively competing with each other to take hold of unexplored resources. China is one amongst them who is aggressively exploring South China Sea defying International Sea laws. In 2019, Victor became the first person to reach the bottom of all oceans and top of all world continents.

Background

It is the brainchild of Explorer Victor Vescovo. He has completed the “Explorers Grand Slam”. The Five Deeps Expedition was organised by a company called Caladan Oceanic LLC. It was founded by Victor himself. The company aims to support expeditions that increase ocean understanding.

Explorer’s Grand Slam

It requires the climbing of highest peaks in all seven continents and also skiing at least 100 kilometres in both North Pole and South Pole.
