  • Advancing Autonomous Underwater Vehicle Technology

    Autonomous underwater vehicles (AUVs) are a mainstay of the subsea survey industry. With unparalleled speed and accuracy in deep water, they have long been the obvious choice for surveys in inhospitable, deep environments. In light of the current downturn in the oil and gas market and the increasing visibility of autonomous vehicles, such as self-driving cars, AUV technology is poised to break ...

  • Ocean outfall plume characterization using an autonomous underwater vehicle

    A monitoring mission to map and characterize the Point Loma Ocean Outfall (PLOO) wastewater plume using an Autonomous Underwater Vehicle (AUV) was performed on 3 March 2011. The mobility of an AUV provides a significant advantage in surveying discharge plumes over traditional cast-based methods, and when combined with optical and oceanographic sensors, provides a capability for both detecting ...

  • Water Treatment Plant: Benefits of Underwater Cameras

    Before fresh water can be made safe for human consumption it must go through a treatment process eliminating bacteria and any other elements deemed unsafe to drink. How does such a process occur and why is it relevant to us? We’ve written about the use of Deep Trekker remotely operated vehicles and pipe crawler systems in storm water systems, sanitation pipes, and water storage basins. A ...

  • Path planning for marine fleet using heuristic approach

    Nowadays, the use of unmanned vehicles for border monitoring is taking over in order to reduce the effort of human operators. This paper addresses the problem of the coastal patrolling by proposing a solution based on unmanned underwater and surface vehicles. The focus of the work is on the design of the routes for the unmanned vehicles so as to optimise the limited mission range of the robotic ...

  • Mobile UW–ASN framework with RSSI–based protocol for shallow river monitoring

    Approximately three–fourths of our planet's surface is covered by ocean and seas, a continuous body of water that is divided into several oceans and smaller seas. Water conditions determine climate that affects life on Earth. Whereas fresh water in lakes and rivers covers less 1%, its contamination significantly damages ecosystems. Within this research this paper proposes a framework with a ...

  • Heroes of the Waters

    A sense of adventure and desire to explore the depths were the inspiring forces behind Deep Trekker. We believe that the more awareness people see underwater the more they care about the oceans and waterways and keeping them clean. Finding that perfect balance between making sure our underwater drones are accessible to everyone but maintaining durable equipment that can withstand serious and ...

  • Dam Inspection: A Day at Still Creek Dam

    We’ve been busy lately visiting various municipalities, police forces, aquaculture sites, and water treatment plants showcasing both our portable ROV systems and our new product line, the DT340 Pipe Crawler. One project in particular, took place at the Still Creek Dam in Tamaqua, PA. Cody and Sam packed up the crawler and headed down ...

  • Q&A: A look at Shell Oil and Arctic offshore drilling

    Shell Oil drill vessels are heading to the Arctic. But they will not be permitted to drill into petroleum-bearing rock until a key piece of blowout response equipment, a capping stack, is on site. The capping stack is carried on the icebreaker Fennica, which arrived early Saturday for repairs in Portland, Oregon. Arctic offshore drilling opponents plan to demonstrate while the Fennica is ...

  • An inflatable tunnel seal stops flooding of world`s largest undeveloped uranium mine

    The Cigar Lake Mine, located in the Athabasca Basin of Northern Saskatchewan, Canada, is sitting on the world's largest undeveloped high-grade uranium deposit in the world. Operated and majority-owned by Cameco Corporation, Cigar Lake is expected to eventually provide more than 10% of the world's mined uranium. But to extract the uranium ore, Cameco has to overcome significant technical ...

  • Hole Dug, Leak Found - City Of Ottawa Entrusts Smartball Platform To Look For Leaks In Tranmsission Main

    When your inspection task is to survey a critical pipeline for leaks, nothing is more satisfying than trusting your technology to predict the leak location and then standing by as the client excavates the area to find a flow of water within one meter of exactly where you said it would be. The above-described "leak-where-predicted" recently happened with the City of ...

  • Should deep-sea mining go ahead in Papua New Guinea?

    Financial disagreement has halted a controversial deep-sea mining project but deeper issues lie with the environment, Prime Sarmiento reports. The fate of a currently halted deep-sea mining project in the Pacific is being watched closely by a number of ...

  • Visualizing the stories data can tell

    Scientists and technologists are turning numbers about everything from condors to ocean-floor contours into visual representations of environmental issues. We’re living in an era of Big Data, but too often it’s nothing more than a fire hose of numbers and data sets that most would have difficulty understanding. Increasingly, though, entities such as non-governmental ...

  • Joint action on climate change: Facts and figures

    Ilan Kelman examines the history, overlaps and conflicts between climate change, development and disasters. By the end of 2015, three global policy processes will have set the stage for how the world responds to major challenges facing humanity in the years to come. A voluntary agreement to tackle disasters was reached in ...
