WHOI: New Discovery Reveals Sharks May Detect and Produce Sound
sounds serve, is not yet understood. Tests of this animal’s hearing range reveal that the clicks produced by rig sharks exceed their low-frequency sensitive hearing range. This raises doubts about whether these sounds play a role in communication between individuals. However, because the initial impulse contains lower frequencies, it's possible that rigs may still be able to hear at least part of them.Nieder’s team is analyzing contextual clues to understand the clicks' purpose. While rigs that were handled produced clicks, and produced significantly more during the first 10 seconds
Connectors Facilitate Camera System for BBC Underwater TV Series
Teledyne Impulse-PDM supplied its Omicron optical fiber connectors to BBC Studios for use in its upcoming underwater natural history series, set to air in 2026. Filming required custom-built camera technology designed to capture extraordinary marine footage from the depths of the Arctic, facilitated by the Rev Ocean’s Aurora ROV.To capture groundbreaking underwater content BBC Studios and Marine Imagine Technologies designed a deep ocean-rated camera system integrated with a telemetry bottle, the central hub for communications on the submersible. However, during the Arctic expedition

Case Study: Floating top marks for piles in flooding rivers
of the river. Generally, the narrow and shallow sections occur close to dams on the downstream side and deeper water close to dams on the upstream side.The development hinges around the concept of a floating top mark that acts as a buoy when moored to the top of the pile. When water level rises the impulse of the top mark-buoy will release the unit from the pile at which point it will float away down river until the mooring line is taught. The unit will then act as a buoy remaining vertical and upright when afloat in low current speeds, although it is improbable the unit will remain vertical
