New Subsea Camera Boasts 4K UHD Image Quality

A new subsea camera from Sidus Solutions, the SS490, is a 4K UHD camera that provides superior video image quality at four times the resolution of 1080 full HD images. According to Sidus Solutions, the camera maintains full 4K resolution while providing excellent focus with a 20x zoom and a combined optical and digital zoom of 144x. The SS490 delivers better picture quality than non-4K models due to its use of HDR (high dynamic range). This is especially helpful with varying lighting conditions such as working with multiple ROVs or reflectivity from stainless steel objects. “We developed

It will be one of the first autonomous underwater vehicles (AUVs) to feature the capabilities and characteristics of a remotely operated vehicle (ROV). In partnership with Saab Dynamics, Modus has developed the Saab Sabretooth to offer greater endurance and speed, and is also developing advanced sensor payload packages and operating methodologies. The vehicle is expected to contribute to more cost-effective survey and inspection projects

Kongsberg Maritime: Reshaping Underwater Operations

Eelume AS has released the first live video footage of its game changing take on underwater intervention vehicles. With the support of Kongsberg Maritime as a development partner, the unique new Eelume robot has torn up the marine robotics rulebook to create a futuristic, snake-like vehicle designed to live permanently underwater and carry out underwater intervention tasks that would normally require the mobilisation of expensive surface vehicles for divers or to launch and retrieve ROVs or AUVs. The footage captured at the PREZIOSO Linjebygg Subsea Test Center during trials in the Trondheimsfjord

Litter Levels in the Arctic Depths On the Rise

The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in a study by researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). Plastic bags, glass shards and fishing nets: despite its location, far from any urban areas, the amount of litter in the depths of the Arctic Ocean continues to rise, posing a serious threat to its fragile ecosystem. Since 2002, AWI researchers have been documenting the amount of litter at two stations of
