SonarWiz 7 Introduces Seabed Characterisation Tool

One feature of SonarWiz 7 is the Seabed Characterisation tool. It incorporates bathymetric slope, roughness, TPI and any spatially distributed variable that can aid the characterisation algorithm to generate classes of texture.  From that, it produces a vector polygon layer that can be exported for use outside SonarWiz. Unlike producing the analysis in a GIS or image processing package, SonarWiz performs the analysis BEFORE the data is mosaiced and geo-referenced. This greatly reduces the impact of artifacts in the nadir and far field, which can be difficult to remove and cause unnecessary rework.   (read more)

Seabed Geosolutions Mobilises Ocean Bottom Node Survey

Seabed Geosolutions has been awarded a 4D baseline ocean bottom node project in West Africa, with a duration of six weeks. The crew is currently in the mobilisation phase of the project. The bottom node survey project will support the optimisation of the recovery rate during the development and production phases of oil and gas fields, by providing high quality data on hydrocarbon prospects, reservoir characteristics and potential geohazards. The project positions the company well to respond to other potential projects in the region.   (read more)

ISE Explorer AUVs to Map Arctic Seabed

International Submarine Engineering handed over two Explorer Autonomous Underwater Vehicles (AUVs) to Natural Resources Canada (NRCan) on 22nd September 2009 at a ceremony held onboard ISE's research vessel in Indian Arm, BC. The event was attended by Mr. John Weston, Member of Parliament for West Vancouver and the Sunshine Coast on behalf of the Honourable Lisa Raitt, Minister of Natural Resources.   The vehicles will be deployed to the high Arctic next year to map the seabed in support of Canada's land claim under Article 76 of the United Nations Convention on the Law of the Sea (UNCLOS). Canada has... (read more)

Introduction Seabed Surveying using ROVs/AUVs

We will cover the installation of vessel and ROV survey equipment and explain the importance of offsets, calibrations and installation checks. We will discuss the relevance of the installation positions on both vessel and ROV in providing the best quality data without interference and explain the different types of surveys and the equipment needed to ensure accurate time stamping. Should you be interested, send us a message and we will forward more information. (read more)

Sonar Studies Reveal New Mediterranean Seabed Features

Unusual seabed features have been revealed in the Mediterranean just beyond the Rhône mouth by a team from the Southampton Oceanography Centre (SOC). Working with a range of sonar equipment from Marine Electronics Ltd of Guernsey, the EU funded team obtained clear images of what they believe to be gas escape features on the delta front. The equipment also revealed deep channels cut into the delta, suggesting the activity of hyperpycnal flows - high density sediment currents capable of scouring the seabed. The survey was part of the Eurostrataform project which is being coordinated by SOC and has been created... (read more)

International Seabed Habitat ­Mapping Conference - GeoHab 2013

The 12th Geological and Biological Seafloor Habitat Mapping (GeoHab) conference was held in Rome, Italy, from 6 to 10 May 2013, hosted by the Geological Survey of Italy (ISPRA) together with the Institute for Coastal and Marine Environment (CNR). The conference attracted approximately 200 participants from 25 countries and included a range of posters and oral presentations related to scientific and technical aspects of marine habitat mapping. Some key themes of the conference were: • Multidisciplinary and multiscalar approaches to habitat mapping • National Seabed Mapping Programmes • Predictive Habitat Modelling • Geoscience Characterisation of the Seabed for Environmental Assessment...
