23 SCIETIFIC DIVING The equipment used varies in this field, and is generally chosen based on cost, effectiveness, availability, and risk factors. Open circuit diving is often used because it is widely available and cost effective. Training standards vary around the world, are generally higher than those for entry-level recreational diving, and in some cases are identical to commercial diver training. There are few international agreements that make it easier for scholars from different places to work together on projects of common interest, by recognizing minimum levels of competency acceptable to both parties. Some diving activities to support scientific research Sampling: Scuba diving is a useful method for taking samples from specific underwater locations. Quantitative survey and monitoring: Quantitative surveys and assessments may include quantitative descriptions of biotic populations, the distribution or abundance of a species, group, or other feature, or correlating topography of the sea floor. Behavior of marine life: Scientists study the behavior of marine creatures through direct observation, video, or photography. Environmental Impact Study: Diver monitoring can be quick and effective in determining the scope and extent of environmental disturbances, and samples and measurements can be taken as their effects are observed. Mapping: A live survey by divers may be necessary or preferred, depending on what will be mapped on the map. Diventures Magazine August 2020
