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.

Coral study traces excess nitrogen to Maui wastewater treatment facility

A new method for reconstructing changes in nitrogen sources over time has enabled scientists to connect excess nutrients in the coastal waters of West Maui, Hawaii, to a sewage treatment facility that injects treated wastewater into the ground.

Fish diversity linked to Caribbean coral reef health

The health of coral reefs can be impacted as much by the diversity of fish that graze on them as by the amount of fish that do so, according to a new study. In the paper, the researchers untangle and unveil the powerful effects that biodiversity has on Caribbean coral reefs.

Proximity to land determines how coral reef communities respond to climate change events

Severe weather and environmental disturbances, such as cyclones or thermal coral bleaching, affect specific areas of coral reefs differently, new research has shown.

How coral bleaching threatens Caribbean communities

A new study uses environmental, socioeconomic and management data from 30 Caribbean islands to identify which communities may be most at risk from the social and ecological effects of coral bleaching, which occurs when warm water causes coral polyps to expel algae living in their tissue.

As Disease Ravages Coral Reefs, Scientists Scramble for Solutions

As oceans warm, coral reefs are suffering not only from bleaching but from deadly outbreaks of disease. Researchers are developing remedies, but the key question is whether these solutions can work on a large-enough scale to save vast reef systems from Florida to Australia.
