M3 Bathy Shallow Water Multibeam Approved to IHO S-44 Standard

Kongsberg Mesotech’s M3 Bathy System, a survey system for shallow-water bathymetric applications, is officially designated compliant with IHO S-44. During the testing, which took place in February 2014, bathymetry data from the M3 was collected in depths ranging from 15-40m. The test targets were a series of standard concrete 1m cubes laid along 20m and 40m contours. The results confirmed that the M3 Bathy is capable of achieving bathymetric survey data that meets two orders of IHO standards. The IHO compliance consists of various criteria including vertical accuracy and target detection standards. In order to assess IHO-S44 compliance, these criteria... (read more)

Spray Glider Completes Shallow Operations

A Bluefin Spray Glider recently completed a two-month deployment conducted by the Glider Research and Operations Center (GROC) at FAU's Harbor Branch Oceanographic Institute (HBOI), USA. The operations took place at Pully Ridge near the West Florida Shelf in approximately 60 metres water depth. It performed 3,200 dives over 100 kilometres distance over a period of two months. The Spray's payload included conductivity, temperature and depth equipment and optical scattering and chlorophyll sensors.     Fraser Dalgleish, Ph.D., Director of the Ocean Visibility and Optics Lab at HBOI said that the next survey will be in waters close to a...

Hydroid: From Shallow to Deep

AUVs for Marine Exploration and Survey
Being detached from a vessel increases the range for surveying, making it possible to access deeper and more difficult areas of the sea and oceans. Hydroid LLC develops and manufactures Autonomous Underwater Vehicles (AUVs), building on research and practical use of its REMUS range. As the need for information and surveillance continues to increase, so does the demand for technology that constantly collects data and monitors change in our environment. This has spurred a growing industry in unmanned underwater, air and ground systems capable of continuous collection of data to help people better understand their surroundings and make informed decisions....

FarSounder On-water Demos

FarSounder will be offering on-water demonstrations to interested parties on 3 April 2014 departing from Jamestown, RI, USA. On board of the R/V Cap'n Bert demonstrations of FarSounder’s 3D, forward looking, real-time navigation sonar will take place to show the sonar's navigational and obstacle avoidance capabilities in deep and shallow water. Engineering staff will be available to discuss both navigation and other applications for these sonar systems. Contact FarSounder to reserve a slot as space is limited. Demonstrations will be held throughout the day, departing at various times. (read more)

Deep-water Coral Reefs

Acoustic recognition and geological setting
Cold water coral reefs, notably the stone coral Lophelia pertusa, have been found extensively in deep Arctic waters such as the Norwegian Sea. The use of multibeam echosounding, together with advanced visualisation and analysis tools, has been a key to many spectacular discoveries. The world's largest cold water coral reef - the Røst Reef - was mapped in detail in October 2002. Located in the dramatic setting of a large submarine slide, this provides an excellent example of how catastrophic geological processes can create special marine habitats. Another major reef complex - the Sula Reef - demonstrates how mounds select... (read more)

Geovation Water Challenge Launches

Ordnance Survey’s ninth Geovation® Challenge launched on 1 December 2015, and sees Britain’s mapping agency offering development funding and places on its Geovation programme for ideas that can improve the relationship with water. Individuals, start-ups and existing businesses and organisations are invited to submit their innovative ideas on how to improve the way we use and manage water by 27 January 2016. Ideas identified as possibly having the highest impact will be invited to a Geovation Weekend Camp from 4-6 March 2016, where the innovators will be asked to work on transforming their idea into a prototype venture. Those selected... (read more)

Water Information Concept Study

The Open Geospatial Consortium (OGC, USA) has completed a Water Information Concept Development Study of the application of OGC Web Services standards in the domain of water information, specifically to investigate architectures and practices for cataloguing, discovering, and accessing selected water resources data from very large numbers of distributed datasets.   David Maidment, director, Center for Research in Water Resources, University of Texas at Austin and leader of the Consortium of Universities for the Advancement of Hydrologic Science (CUAHSI) project on Hydrologic Information Systems said, "The Concept Development Study was very useful to the CUAHSI team to set our work...

Water Column Survey Contract

Norbit US has been awarded a contract from the Department of Homeland Security. The assignment was defined as a consequence of the Deepwater Horizon oil spill in the Gulf of Mexico where several glaring technological gaps in responding to oil disasters were revealed. Norbit will use its wide-band multibeam imaging echosounder to demonstrate the capabilities of the sonar's active acoustics capability to detect oil in the water volume; the sensor is designed to fit on a multitude of different platforms, both stationary and moving. One of the issues was determining the location of subsurface plumes and making timely decisions to... (read more)

Water-Tight Cases

B&D have unveiled their latest range of water-tight cases. The Zarges K470 aluminium container has been re-developed to Ingress Protection (IP) 65 protecting its contents against the penetration of liquids and dust. Zarges' engineers developed the cases with TÜV formally certifying the range. The new models include additionally applied internal sealing, an automatic membrane relief valve, improved lid and location stability. Aluminium cases combine light-weight ease of manoeuvre with unrivalled strength and impact resistance. Effectiveness in protecting against water penetration joins the containers' robust protection against extreme fluctuations in temperature from -150 to +150°C. (read more)
