For both the world history and scuba diving, the remote Bikini Atoll located in the Marshall Islands is one of a kind. Popular for being the center of atomic testing during the mid-twentieth century, nowadays this place is highly esteemed among divers for its amazing wreck diving. In 2010, it was declared a UNESCO World Heritage site as part of larger Bikini Atoll Nuclear Test Site.
This central Pacific Ocean’s isolated atoll was known for Operation Crossroads where after World War II, nuclear tests were done by the US creating sunken war ships. These wrecks are historical and have turned into underwater museums that attract advanced divers from all corners of the globe.
Major Attractions
- Wreck Diving: A lot of people visit Bikini Atoll to go wreck diving which offers some of the most notable sunken war ships like an aircraft carrier named USS Saratoga and Japanese fleet’s flagship HIJMS Nagato.
- Marine Life: The wrecks have been underwater for over fifty years and now they act as flourishing artificial reefs harboring a sprawling variety of marine life. Here there are large pelagic fish, colorful coral formations, and many different sea creatures that colonized these underwater time capsules.
- Historical Significance: Every dive in paradise comes with a message on how dangerous nuclear weapons can be while at the same time offering a rare chance to experience first hand naval artifacts.
Where it is Located
Geographical Information
Bikini Atoll is one among Ralik Chain in Marshall Islands consisting of 23 islands surrounding a deep central lagoon. In order to allow testing with nuclear bombs, this atoll received an evacuation notice during 1940s and radioactive remains sealed off access since then. However, diving is conducted in controlled conditions which are regulated to protect the people’s health.
Getting There
- By Air: To get to Bikini Atoll, one has to start with a flight headed for Majuro which is Marshall Islands’ capital city. Most international flights are coming from Honolulu, Hawaii.
- Local Transport: In most cases, divers access Bikini Atoll via approved dive tour operators who organize liveaboard trips starting from Majuro. As it is remote and there is no domestic infrastructure in place, this is practically the only option for reaching the atoll and staying within its borders.
- Dive Site Access: At Bikini Atoll dive operations are carried out from liveaboards that provide access to various dive sites around the lagoon. These specially designed boats have onboard facilities for multiple dives per day under harsh ocean conditions.
Accessing the Dive Site
Because of its exclusiveness as a diving destination, advance planning and booking with a reputable dive tour operator are essential:
- Liveaboard Diving: Whereby accommodation, meals and diving services are available on board making it the sole way to stay and dive at Bikini Atoll.
- Limited Entry: The number of diving takes and their frequency are controlled so as to minimize negative ecological effects due to sensitivity of this site together with its historical background.
One of the most famous and historically important places to dive on wrecks is Bikini Atoll. Each one of these sites offers a unique look into mid-20th century naval history and an amazing explosion of marine life that has engulfed these sunken steel giants.
Wreck Dive Sites
- USS Saratoga (CV-3): This is the largest aircraft carrier in the world which can be dived on. Lying in shallow waters, this massive wreck can be explored from the flight deck all the way down to the hangar bays where they have historical artifacts as well as marine life inside.
- HIJMS Nagato: The former flagship of Japanese navy and planner of Pearl Harbor attack lies upside down in deeper waters. The enormous guns, twisted hull and eerie superstructure make it a difficult dive for experienced divers.
- USS Arkansas (BB-33): A veteran of two world wars, this battleship was sunk during nuclear tests and now rests as an interesting diving site for advanced divers due to its depth and structural complexities.
Description of Underwater Topography and Features
- Depth Ranges: Diving into Bikini Atoll could take you deeper or shallower depending on the point chosen with some such as USS Saratoga starting at 18 meters (60 feet) while others like HIJMS Nagato lie at depths exceeding 50 meters (165 feet).
- Visibility: In lagoon visibility usually remains very good ranging from 20 – 30 meters (65 – 100 ft), because of isolation here sediment is not an issue.
- Currents: With moderate tidal movements across different areas within reef system, currents are usually weak around atoll’s rim but can become quite strong between islands.
Marine Life
Despite several destructive past episodes within this atoll, today Bikini Lagoon is a thriving marine sanctuary. They are covered with corals hence becoming artificial reefs and teeming with life, which forms a strange contrast with the violent past.
Species Diversity
- Coral Growth: Wrecks’ sunken hulls have developed into thriving artificial reefs. The structures are now covered in both hard and soft corals providing homes for multiple marine species.
- Marine Life: Divers can find various types of tropical fish that swim around the wrecks including open ocean roaming schools of pelagic fish like barracuda and tuna. This also brings in large predators such as sharks.
- Unique Encounters: There are several rarely sighted species living within the mostly undisturbed waters of Bikini Atoll just to mention but one is grey reef sharks that appear albino white or ghostly white.
Conservation Efforts
- Protected Status: There are strict rules meant to protect natural and historical resources at Bikini Atoll making it part of Marine Protected Area (MPA).
- Eco-Sensitive Diving: Dive operators are committed to conservation efforts by maintaining a no-touch rule on dives, limiting number of divers per site, and informing visitors about ecological and historical importance of the atoll.
Bikini Atoll is an exceptional diving destination in the world due to its combination of remarkable wreck dives and active marine ecosystems. These chapters reveal different dive sites available together with an abundance of marine life that has taken over remnants from naval history, thus offering divers a truly moving underwater experience full of awe-inspiring beauty.
