Term Paper On Scuba Diving Business Internet Plan
The direct observation and manipulation of marine habitats afforded to scuba-equipped scientists have transformed the marine sciences generally, and marine biology and marine chemistry in particular.
Underwater archeology and geology are other examples of sciences pursued underwater.
The field of ocean acidification and the impact of anthropogenic carbon dioxide emission has seen similar growth and most of the cited articles in this field have relied to a significant extent on data collected during scuba diving operations.
The field of paleoclimate reconstruction has a major influence on the understanding of evolution and the ecological and biogeographic past, as climate is the most powerful driver of evolution.
The legal definition of scientific diving varies by jurisdiction.
Scientific divers are normally qualified scientists first and divers second, who use diving equipment and techniques as their way to get to the location of their fieldwork.
Scientific diving in the course of employment may be regulated by occupational safety legislation, or may be exempted as self-regulated by a recognised body. Collection of scientific data by volunteers outside of employment is generally considered to legally be recreational diving.Advances in training and accessibility to trimix diving and closed circuit rebreather systems has enabled scientific divers to reach highly diverse deeper mesophotic reefs which may be the corals last refuge from the warming of surface waters.The current knowledge of the functioning of the ecologically and economically important hard-bottom communities in the shallow water coastal zones is both limited and particularly difficult to study due to poor accessibility for surface operated instrumentation as a result of topographic and structural complexity which inhibit remote sampling of organisms in the benthic boundary layer.Training standards vary throughout the world, and are generally higher than for entry level recreational diving, and in some cases identical to commercial diver training.There are a few international agreements that facilitate scientists from different places working together on projects of common interest, by recognising mutually acceptable minimum levels of competence.Many of the measurable changes in global climate occur in the sea.Coral bleaching is an example of an indicator of change, and scuba diving has provided a large amount of low-impact observational data contributing significantly to the large body of knowledge on the subject over several decades.Scientific diving is any diving undertaken in the support of science, so activities are widely varied and may include visual counts and measurements of organisms in situ, collection of samples, surveys, photography, videography, video mosaicing, benthic coring, coral coring, placement, maintenance and retrieval of scientific equipment.Underwater diving interventions, particularly on scuba, provide the capacity for scientists to make direct observations on site and in real time, which allow for ground-truthing of larger scale observations and occasional serendipitous observations outside the planned experiment.Human dexterity remains less expensive and more adaptable to unexpected complexities in experimental setup than remotely operated and robotic alternatives in the shallower depth ranges.Scuba has also provided insights which would be unlikely to occur without direct observation, where hypotheses produced by deductive reasoning have not predicted interactive and behavioural characteristics of marine organisms, and these would not be likely to be detected from remote sensing or video or other methods which do not provide the full context and detail available to the diver.
