Sentence examples for underwater active from inspiring English sources

In this paper, we designed a two-dimensional (2D) experimental platform of underwater active electrolocation system by simulating weakly electric fish.

Results indicated that surface shape of 3D location characteristic curves for the 2D underwater active electrolocation positioning system was convex upwards or concave down which was influenced by the material of probed objects and the frequency of the electric field excitation signal.

By exploiting that reflex, free divers can remain active underwater for more than four minutes, and much longer if they remain still.

A light and thin underwater large-plate active acoustic structure is developed that satisfies the particular requirements of high pressure resilience, low frequency and high efficiency encountered in underwater work environments.

The extremely loud underwater noise from active sonar and ship sinking explosions will propagate for hundreds of miles through the offshore ecosystem, and have "the potential to disturb, injure, or kill marine mammals".

This enriched site is of course aligned to a volcanic ridge, near North Su, an active underwater volcano, an area where temperature, pH conditions, and the lightless environment also supports unique and profuse concentrations of heretofore unknown forms of marine life supported by the very same natural circumstances that manufactured the extreme mineral concentrations to be mined.

Normally, such fossils would be deep underwater, but the geologically active part of New Guinea where the team collected its samples has been rising from the sea at a fast pace, exposing ancient reefs that would otherwise be nearly impossible to find.

As a type of active acoustic detection, underwater seismic exploration is widely used in the detection of potential seabed oil, natural gas resources reservoir, combustible ice, and other resources.

As a type of active acoustic detection, underwater seismic exploration is one of the main technical means to implement the marine acoustic exploration of potential seabed oil, gas resources reservoir discovery, and refinement of in-fill drilling monitor.

The data from the corresponding water depths (50-cm intervals down to 10 m) and times (hourly, before dawn to sunset, several days) were related to the highly resolved (2 nm) underwater ultraviolet radiation (UVR)/photosynthetic active radiation (PAR) transparency (290 to 700 nm).
