OceanGate Begins Building a New 5-man Sub

Manned submersible operator OceanGate Inc. said it has started building Cyclops 2, an all-new privately owned sub capable of taking five people to depths of 4,000 meters – or approximately two and half miles deep – for human exploration of more than 50 percent of the ocean depths.   Having been in development for several years, with initial design and engineering beginning in 2013, Cyclops 2 has now entered the construction phase with an order for two titanium hemispheres and two matching titanium to carbon fiber interface rings from fabricator of reactive metals Titanium Fabrication

Airborne Hydrographic Survey Commissioned After NZ Earthquake

of the South Island.   RAN LADS commanding officer, Flight Lieutenant Commander Susanna Hung, explained the mission. “We will fly over the area and collect hydrographic survey data, which will reveal what has happened below the waterline, and identify any shifts in the ocean floor which mariners need to be aware of.”   The RAN’s Airborne LiDAR Bathymetry (ALB) system has been developed by Fugro for safe, high speed and cost effective surveys of shallow coastal areas. Under a long term contract to the RAN, Fugro provides the LADS technology, a de Havilland Dash 8-202

New Cyanobacteria-Sensitive Optics for Enviro-T2 In-Line Fluorometer

Turner Designs’ Enviro-T2 detects Cyanobacteria in a low-cost in-line monitor Enviro-T2 is an in-line fluorometer suited for drinking water or wastewater facilities that want to detect cyanobacteria and algae in their water flow. It is an accurate, single-channel fluorometer which easily integrates with data collection systems providing a 4 – 20 mA output proportional to the fluorescence from chlorophyll in water. The Enviro-T2 Red Excitation Fluorometer has maximum sensitivity for better detection of cyanobacteria; the Enviro-T2 Blue Excitation Fluorometer is configured with maximum

AUVs Under Ice: Past Milestones, Promising Future

The marine environments beneath ice are arguably some of the least accessible on earth. Ice is a formidable physical barrier that can range in thickness from centimeters to hundreds of meters—an impediment that has not diminished our desire to uncover the secrets that lie beneath.    In the heyday of manned submarines, under-ice was seen as an important operating theater, where the ability to listen and monitor one’s foes was crucial. As manned submarines have given way to unmanned vehicles, the duties of under-ice research have widened to include more fundamental motivations
