Large-scale Hydrographic Survey

MMT AB (Marin Mätteknik AB) has been awarded the 2009 Mareano survey contract by the Norwegian Hydrographic Service. The survey will commence in mid-May 2009 and will cover an area of almost 5000 km2.   The survey will include bathymetric data acquisition and processing in an area near Eggakanten outside the Troms region in the Norwegian Sea, WNW of Tromsø, Norway. The area to be surveyed is within the depth range from 200 to 1000 metres. Apart from the hydrographical survey the assignment also includes gathering reflectivity data and a gravimeter survey. The assignment will be conducted by MMT AB... (read more)

Hydrographic Survey Data Integration

Combining independent data sets to present the full picture
The next step in the presentation of hydrographic survey data is the integration of separate data sets into navigable three-dimensional models. Software tools now available allow contractors to produce geo-referenced presentations of various data sets including bathymetry, sonar imagery and sub bottom information. By combining these data sets together into a three dimensional model the contractor can provide the end user with tools that allow informed decisions to be rapidly made about the suitability of an area for the proposed purpose. These presentations also provide the contractor and end users with a powerful tool for gauging the quality of the... (read more)

Hydrographic Survey Charting Using GIS

PD Ports is streamlining the way it shares hydrographic data by using GIS software from British software developer, Cadcorp, at Teesport. Handling around 40 million tons of cargo per annum, Teesport is a major deep-water complex and one of the largest container ports in the north of England. The first priority is to ensure the safe movement of the considerable amount of river traffic handling that cargo. Teesport relies a lot on hydrographic survey charts which provide an up-to-date record of the depth of the river in berths, approaches and channels. Captain Jerry Drewitt, Harbour Master for Teesport and Hartlepool,... (read more)

USACE Hydrographic Survey Boat Named

The U.S. Army Corps Buffalo has named the latest addition to its high-tech hydrographic survey fleet after retired Command Sgt. Maj. Micheal L. Buxbaum of the U.S. Army on 23 June 2015. The addition of the survey vessel Buxbaum enhances Buffalo District’s ability to support USACE’s navigation mission with a third survey vessel equipped with a multibeam sonar system to meet increased production goals during peak periods. The Buxbaum will a part of the multibeam sonar be equipped with a vessel-mounted Lidar system. The Optech Ilris 3D laser scanner has the capability to collect data in a terrestrial (static) mode...

CEE-USV Remotely Operated Hydrographic Survey Boat

With a purposeful-looking remotely operated hydrographic survey boat package, CEE HydroSystems USA has added a factory-option USV to its shallow-water bathymetry product line. The survey vessel is 1.9m and equipped with a singlebeam echosounder. The key to the CEE approach is to bring all components together; instead of multiple components cabled and connected, the CEE-USV has a single data module presenting a simple user interface. Adrian McDonald of CEE characterises its purpose saying that If the users are aiming for a science project – don’t buy this USV. With a design aimed to minimize the requirement for specific system expertise,... (read more)

NOAA Plans for 2011 Hydrographic Survey Season

As the new year approaches, NOAA ships and independent contractors are preparing for the nation's 177th hydrographic surveying season, aiming to collect critically needed ocean and coastal mapping data for 2,525 square nautical miles in high-traffic coastal waters of the continental United States and Alaska.   US waters cover 3.4 million square nautical miles including a constantly changing coastal environment due to storms, erosion and other coastal processes. To ensure the continued flow of commerce, NOAA's Office of Coast Survey maintains the nation's suite of more than 1,000 nautical charts. To ensure the accuracy of charts, the Office of Coast...

Hydrographic Survey Linked to Mass Whale Stranding

A mass stranding of melon-headed whales occurred in May-June 2008 in the Loza Lagoon system in Madagascar. About 100 open-ocean mammals mysteriously entered the shallow estuarine system. Recently, a report by an independent scientific research panel of the International Whaling Commission examining the cause of the stranding was presented. It points to a hydrographic survey that was taking place about 65km offshore using a high-power 12kHz multibeam echosounder. The research report excluded seismic airguns being used in the offshore and oil industry as they were working after the stranding took place. The hydrographic survey was concentrating on the shelf break abouit... (read more)

Hydrographic Survey of the Normandy Beaches

Ambitious Project Collecting Terabytes of High-resolution Bathymetric Data
In the summer of 2013, several companies and individuals volunteered to conduct a hydrographic survey off the D-Day beaches of Normandy, France. The first phase of the survey was conducted over the course of 27 days. The purpose of the survey was to collect as much data as possible with multibeam sonar to create a map of both bathymetry and side-scan data. Throughout the survey the survey lines were adapted as the end neared to ensure that the data set was complete without any gaps. This required assessing the importance of some areas to determine if they should be eliminated... (read more)
