The relative distance and angle of two subsea structures is often determined using a deep-sea structure pose measurement system; thus, the high accuracy of pose measurement has important significance for the success of deep-sea operations.
Calcification takes energy, so increased biological energy needed to form and maintain deep sea coral structures may diminish the corals' other biological processes, including reproduction.
Along the gradient formed by the surface sediments from wetland, estuary to the coastal and deep sea, the community structure changes of beta-AOB were detected and dominated lineages were identified so as to draw a general view about the spatial distributions of beta-AOB in this area under increasing pressure of anthropogenic influences.
Some fish living in the deep sea have reduced eyelike structures directed downward (e.g., Bathylychnops, which has a second lens and retina attached to the main eye); it is thought that the function of these structures is to detect bioluminescent creatures.
The appropriate design of a mooring system to maintain the position of an offshore structure in deep sea under various environmental loads is important.
Some species of deep sea stony corals form complex structures that provide similar – although not identical – ecosystem services as shallow tropical reefs: habitat for abundant and diverse associated fauna, commercial fish breeding grounds, and potential medicines for human use.
The phylogeny supports the hypothesis that both structures evolved in the deep sea (Figure 2).
Spar platform is an innovative marine structure designed to conduct such deep sea explorations.
In March, a fire broke out in one informal settlement, Deep Sea, leaving up to 90% of the housing structures destroyed and about 10,000 people homeless.
In order to better define the role of amino acid substitutions on deep sea adaptation, we mapped PS sites on the 3D structure as well as on protein topology in respect of trans-membrane regions.
At first the eruptions resemble those that occur in the deep sea, forming piles of pillow lava at the base of the volcanic structure.
