2 Why do many scientists believe that organisms similar to those found at Earth's deep-sea
vents may exist on other planets?
Using coral-crushing roller and rockhopper gear on their nets, trawlers can fish in deep-sea
canyons and over rough seafloor, once avoided because of the damage they caused to nets.
stocks are caught in deep waters beyond the main fishing grounds on the continental shelves.
It is now up to EU fisheries ministers and the EP to show similar resolve," adds the NGO, which urges them to strengthen the proposal by: requiring impact assessments for all deep-sea
fisheries, not just for new fisheries; requiring closure of deep-sea
areas to fishing where vulnerable marine species are known or likely to occur unless these areas can be managed to prevent significant adverse impacts; and requiring that all catches, including by-catches, be sustainable and that all by-catches be landed unless there is adequate justification (eg high survival potential) for throwing catches back.
The most significant of these discoveries were the reefs of deep-sea
coral, the first deep-sea
coral reefs to be found offshore Israel.
That's important because deep-sea
coral communities appear to be very old and very fragile.
They'd begun searching for deep-sea
photosynthesizers a decade ago, after coauthor Cindy van Dover of the College of William and Mary in Williamsburg, Va.
Which water sample could have been taken from near a deep-sea
Very few individuals are qualified to undertake identification of species in even one of the groups of deep-sea
animals, and we were fortunate to have a high proportion of the world's deep-sea
taxonomic experts working on this project.
We fought for the best possible protection for deep-sea
fish and vulnerable marine ecosystems.
They are now known from subtidal waters at high latitudes, but deep-sea
species occur in most of the world's oceans, typically living at depths between 500 and 1500 metres.
The videos showed clams that Smith recognized as relatives of those observed in the remarkable underwater communities that had been discovered a decade earlier around deep-sea
vents and seeps.
