Mangrove & Coral Destruction

Widespread destruction of mangroves (Bahamas, Australia) and Coral Reefs (Caribbean, Red Sea) has resulted in the loss of some of the worlds most diverse ecosystems. As a side effect, this has greatly increased shoreline hazards and beach erosion rates. The greatest benefit of mangroves is their ability to reduce storm surge. This benefit is long-term and requires no maintenance. The 1999 super typhoon, Orissa, killed over 10,000 people in India drowning many with its powerful storm surge. This number could have been lower if the mangroves had been retained. Mangroves are lost because of clearing for development, logging, and shrimp farming. Coral reefs are lost by mining (Bali, Indonesia), sedimentation from agriculture on the upland (St. Croix, Virgin Islands), bad fishing techniques that kill corals (Pacific Islands), sedimentation from nourished beaches (Waikiki) and a host of other natural and global warming-related causes. Dubai is perhaps the single greatest example of coral reef destruction. The artificial islands built there buried vast coral reefs. Mangroves and coral reefs often provide protection for nearby beaches. Their destruction harms the beach as well.

Conserving Canada’s Diverse Marine Life

Despite the deep, cold waters, newly discovered undersea mountains off Canada’s west coast are home to a rich diversity of life. The recently designated Offshore Pacific Area of Interest, is a 140,000 square kilometre region 100 to 200 kilometres west of Vancouver Island in the province of British Columbia.

Managing wastewater to support coral reef health, resilience

Coral reefs provide food and livelihoods for hundreds of millions of people around the world, support more than a quarter of all marine life, and protect communities and coastlines from natural disasters—and if urgent action is not taken, we risk losing them forever.

Study tracks severe bleaching events on a Pacific coral reef over past century

A new study has uncovered the history of bleaching on a reef in the epicenter of El Nino, revealing how some corals have been able to return after facing extreme conditions.

Florida’s coral reefs provide window into the past

The Florida Keys coral reefs stopped growing or significantly slowed their growth at least 3000 years ago and have been balanced between persistence and erosion ever since, according to a new study by the U.S. Geological Survey.

Climate change modifies the composition of reefs

Corals devastated by climate change are being replaced naturally by other species such as gorgonians, which are less efficient in acting as a carbon sink. A study has analyzes for the first time why gorgonians are more resistant than corals to human impacts and global climate change.

Catastrophic construction: Storms can build reef islands in atoll regions

Many coral reef islands, or atolls, are created by water moving sand and gravel, piling it up into consecutive ridged layers. However, new research has uncovered a different type of island construction: storm-deposited boulders.
