Ocean acidification may also have an effect of 'gender discrimination' as spawning female corals are significantly more susceptible to the negative effects of ocean acidification than spawning male coral [73] Bamboo coral is a deep water coral which produces growth rings similar to trees. The growth rings illustrate growth rate changes as deep ...
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
The compression effects may occur when descending below 500 feet (150 m) at rates greater than a few metres per minute, but reduce within a few hours once the pressure has stabilised. The effects from depth become significant at depths exceeding 1,000 feet (300 m) and remain regardless of the time spent at that depth. [42]
A 2015 bleaching event wiped out half of Hawaii's coral reefs, and most were off of Hawaii Island and Maui's shores. In the worst-case scenario, scientists say coral reefs could be extinct in 30 ...
The Caribbean's coral reefs have been increasingly becoming diseased by 20 percent. [19] Coral diseases can cause tissue damage or it could even destroy the entire colony. [19] In 1980, white-band disease killed 95 percent of the Acroporid palmata and Acroporid cervicornis colonies which placed them on the Endangered Species Act. [15]
Red List assessments of cold-water corals, which are found in colder, deeper waters around the world and do not depend on sunlight, are ongoing, with threats including fishing activity, especially ...
Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).
The largest yet known deep coral reef "has been right under our noses, waiting to be discovered,” said Derek Sowers, an oceanographer at the nonprofit ... the reef's size remained a mystery ...
