# Diving in the Maldives

The Maldives, officially the Republic of Maldives, is a small archipelagic state in South Asia. It lies in the Indian Ocean southwest of Sri Lanka and India, about 700 kilometres (430 mi) from the Asian continent's mainland. The chain of 26 atolls stretches across the Equator from Ihavandhippolhu Atoll in the north to Addu Atoll in the south. The land area is roughly 298 square kilometres (115 sq mi). Malé is the capital.
The Maldives has white sand beaches, coral reefs, clear warm waters, numerous scuba diving sites and rich marine life. Most holiday resorts in the Maldives have a scuba diving facility and there are a number of liveaboard operators offering scuba diving cruise holidays.
In the 1998 global coral bleaching, much of the coral in the Maldives was bleached due to the El Niño event combined with global warming. In 2016, global warming and the El Nino event heated the Maldives, which, with land reclamation and water pollution, bleached and killed 75% of corals in the Maldives.

## History

The Maldives has been growing in popularity as a scuba diving destination since the 1970s when the number of resorts began to increase.

## Statistics

Tourist arrivals to the Maldives have been growing steadily for the past ten years, with the exception of 2005 (the year after the tsunami), when the numbers dropped. Around 700,000 tourists visit the Maldives each year (2008).

## Impact of climate change on the underwater environment

Climate change has severely impacted coral reefs around the world as has been widely reported such as the effects of the El Niño in late 1990s, according to some around 60%-80% of the corals have been bleached in several areas in the world including the Maldives reefs.

## Impact of tourism on the underwater environment

Reports have described the socio-economic impact on the environment as a result of mass tourism expansion in the Maldives.

## Diving destinations and sites

The Maldives comprises mainly open water, with only 1% of the country being land-based. The land is spread over 1,192 islets, each of which forms part of an atoll. In total, there are 26 atolls in the Maldives. The following atolls are home to some of the dive sites.
The Maldives offers different types of dives, but most are characterized by medium to strong currents.
Each island in the Maldives has its own lagoon, which is usually not very deep.
Terminology:
* A thila is an underwater pinnacle.
* Kandu are diving spots around the border of the atoll.

### Ari Atoll

Located in the western part of the Maldives, Ari Atoll is one of the largest atolls and has a wide selection of dive sites, including:
* Diguri Guri: A dive site near Ellaidhoo.
* Broken Rock: A dive site named for the large broken rock at its center. It is home to soft and hard coral formations that attract a wide variety of reef fish.
* Gangehi Kandu: Recommended only for advanced scuba divers, the Gangehi Kandu is a dive site in the northern part of the Ari Atoll. Currents here can be an issue, and the site should only be dived when the currents are flowing into the site.

### South Malé Atoll

The Male Atoll is divided into 2 sections, the North Male Atoll and the South Male Atoll.
* Cocoa Corner (Cocoa Thila): A dive site that can be explored in several different ways. With the right current and conditions, it is the best shark show around Male Atoll. A safety float is required, and divers should be prepared to make a midwater safety stop.
