Deep water coral habitats are also threatened by human activities, particularly by indiscriminate trawling. These ecosystems have been little studied, but in the perpetual darkness and cold temperatures, animals grow and mature slowly and there are relatively fewer fish worth catching than in the sunlit waters above.
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 ...
Exposure to ultrasound in excess of 120 dB may lead to hearing loss. Exposure in excess of 155 dB may produce heating effects that are harmful to the human body, and it has been calculated that exposures above 180 dB may lead to death. [citation needed] It is said that some naval anti-frogman defences use powerful ultrasound.
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with the body, and the surrounding gas or fluid. [13] It typically occurs when the organism is exposed to a significant change in ambient pressure , such as when a diver ascends or descends.
On a recent expedition, a group of ocean researchers discovered 85 miles of deep-sea coral reef off the coast of the southeastern US.
Some Florida Keys coral reefs are losing their color weeks earlier than normal this summer because of record-high water temperatures, meaning they are under stress and their health is potentially ...
The satellite-based mapping and prediction service calls for a 90% chance of coral bleaching occurring in the Caribbean in the next four months, with the biggest damage near Florida likely in ...
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 ...
