There are many variations of the Cartesian diver methods, such as making one from clay, a paperclip and a straw.
The science and technology of mechanical, abrasive water jet, diamond wire, and diver torch methods is reviewed, and the factors that play a role in the decision to use explosive or non-explosive severance methods is described.
For coastal reef seascapes we rely on the same diver survey methods that are used to keep track of reef-dependent wildlife species.
To lay a pipeline this far down, the Norwegian authorities financed a series of test dives, with the American diving industry helping develop safe methods to allow divers to work up to 1,300 feet beneath the waves.
To lay a pipeline this far down, the Norwegian authorities financed a series of test dives, with the American diving industry helping develop safe methods to allow divers to work up to 400 metres beneath the waves.
This is considered a better way to count reef sharks than the previous prevailing method, in which divers counted fish while swimming under their own power.
As for the effect of these two methods on perinatal outcomes, divers studies show that LMP is associated with a higher incidence of adverse outcomes, including preterm, postterm, and growth fetal restriction [ 26- 29].
Our goal was to quantify the relative magnitude of the diver effect in three different census methods.
For each simulation, a diver from each of the two census methods was placed in the centre of the sample area and each had an orientation of 90° (each facing in the same direction) at initial time, t0.
This method is used by free divers to get their body and their brains used to the sensation prior to going under.
