The state of the art fisheries research vessel Bell M. Shimada, operated by the North West Fisheries Science Center has become the latest ship to feature the Oceanscience UnderwayCTD moving vessel underway profiler. The NOAA ship was commissioned in 2010 and operates off the coast of the Northwestern US. The Bell M. Shimada is the first of two new vessels for NOAA fisheries research, the second being the Reuben Lasker that will be operated by the South West Fisheries Science Center. As part of an initiative to improve productivity, NOAA scientists identified the UnderwayCTD as a tool to allow them to gather high quality CTD data while underway instead of relying on inferior methods. Prior to receiving their UnderwayCTD, technicians on board dropped expendable temperature probes (XBT) during their surveys. The XBTs were their only real option and were far from satisfactory in terms of data quality and sustainability. Replacing the XBTs with UnderwayCTD deployments will eliminate or greatly reduce this seafloor waste generation activity, in a small part reducing the environmental footprint of the fisheries surveys.
Two complete Oceanscience Underway SV systems including theValeport Rapid SV profiler were recently supplied by Swathe Services (Australia) to IXSurvey Australia ahead of a challenging hydrographic survey project in the Fiordland National Park, New Zealand.
During a trip to Greenland in September 2013, researchers from Oregon State University's College of Earth, Ocean and Atmospheric Sciences used their Oceanscience Q-Boat 1800 remote survey boat, usually at home in rivers and streams and not the Arctic Ocean, to gather current, termperature, and salinity measurements in otherwise inaccessible regions close to the ice.
The Oceanscience Group has unveiled the first Z-Boat 1800 remotely-operated survey boat with integrated side scan sonar, from Tritech International. The new boat provides a shore operator with real-time high definition side scan imagery from Tritech's StarFish 990F side scan on a portable 1.8m surface vessel.The StarFish side scan is attached to a ...
BioSonics, Inc. and The Oceanscience Group announced the release of a portable remotely-operated habitat-mapping survey boat, the Z-Boat 1800MX. A combination of Oceanscience's proven remote hydrographic survey boat and BioSonics' industry-leading MX echosounder, the Z-Boat 1800MX allows researchers to obtain quantitative measurements of aquatic vegetation and substrate distribution without the expense and effort of launching a manned boat.
The Federal Service for Hydrometeorology and Environmental Monitoring of Russia (Roshydromet) has embarked on a widespread program of modernization of its environmental instrumentation and infrastructure.
The Federal Service for Hydrometeorology and Environmental Monitoring of Russia (Roshydromet) has embarked on a widespread program of modernization of its environmental instrumentation and infrastructure. Partly funded by the World Bank, the project will result in an enormous improvement in the ability of the organization to monitor surface water hydrology and hydrography. As part of the project, an initial fleet of 15 Oceanscience Z-Boat® 1800 remotely-operated hydrographic survey boats has been delivered to Russia through Oceanscience's exclusive project partner, INFAX Inc.
Thanks to Markus Janout from the Alfred Wegener Instutute Helmholtz Center for Marine and Polar Research (AWI) for sending in photographs and information about the recent UnderwayCTD activities on the TRANSDRIFT XXI cruise to the Russian Arctic on board the research vessel Viktor Buynitskiy. Markus and his colleagues were joined by researchers from the Institute for Polar Ecology, Christian-Albrechts-University of Kiel (IPE Kiel University) and by the Academy of Sciences and Literature Mainz (Mainz Academy). The UnderwayCTD was used in the icy waters on several transects, and provided convenient densely-spaced upper ocean temperature and salinity profiles.
With the help of some favorable weather, the first official Oceanscience Z-Boat demonstrations in Canada were completed in early November 2013, concluding just as the first big snow of the year started coming down. While in Alberta for the Tailings and Mine Waste 2013 Conference in the spectacular mountain town of Banff, optimism prevailed and three days of demonstrations were arranged in Calgary to coincide with the conference; fingers were immediately crossed in the hope that the weather would cooperate.
In 2013, TerraSond (Alaska, USA) completed a major hydrographic project for NOAA in the Chukchi Sea in northwestern Alaska for the purpose of nautical chart updating for safety of navigation. The surveyors planned this shallow water survey within ...
Approximately 4,000 nautical miles of multibeam and sidescan sonar data were collected to survey 180 square nautical miles of seafloor in a remote, poorly charted region of the Arctic experiencing increases in freighter traffic during the limited ice free season.
Familiar with the SV challenges in these waters, TerraSond previously installed large profiling winches on their survey vessels when sound velocity variability could be a substantial source of uncertainty.
Featured Survey: Terrasond Multibeam Charting Survey for NOAA
In 2013, TerraSond Limited (Palmer, AK) completed a major hydrographic project for NOAA in the Chukchi Sea in northwestern Alaska for the purpose of nautical chart updating for safety of navigation. Approximately 4,000 nautical miles of multibeam and sidescan sonar data were collected to survey 180 square nautical miles of seafloor in a remote, poorly charted region of the Arctic experiencing increases in freighter traffic during the limited ice free season. As the surveyors at TerraSond planned this shallow water survey within their long-term NOAA contract, they realized that the troublesome sound velocity conditions in the survey area were a key factor to consider. Without enough SV profiles, the quality of the final product to the client could be compromised. Stopping the survey vessel to conduct regular SV dips was also ruled out as the sidescan towfish would have to be recovered onboard for every cast, resulting in an unacceptable amount of survey downtime. Familiar with the SV challenges in these waters, TerraSond previously installed large profiling winches on their survey vessels when sound velocity variability could be a substantial source of uncertainty. For the most recent survey, it was decided that the Oceanscience UnderwaySV profiler would be used instead of a larger winch. A compact system with simple operation and automated wireless data management, it represents a good balance between useability and performance.
The continued paralysis of the U.S. government is being felt around the world, even at some of the most remote scientific outposts on the planet. As the partial shutdown extends into its second week, the National Science Foundation (NSF) has directed its scientists and its primary logistical contractor – Lockheed Martin – to wind down operations and initiate “caretaker” status.
The Oceanscience Z-Boat 1800 remotely-operated hydrographic survey boat has just completed final trials with an on-board autonomous waypoint navigation system, and is now ready to get surveying. The latest GNSS controlled, IMU aided "robo" Z-Boat option is a result of a partnership between The Oceanscience Group (USA), MSubs (UK) and Swathe Services (UK) and adds autonomy to the substantial list of options for the 1.8 m (6 ft) portable hydrographic survey system. While under manual or autopilot control, the Z-Boat can gather single or dual frequency echosounder bathymetry, side scan imagery, water quality or ADCP velocity data.
The Oceanscience Group is pleased to announce their appointment as an authorized HYPACK® OEM partner, to further strengthen the available options for the popular Z-Boat® 1800 remotely-operated hydrographic survey boat. Oceanscience can now supply their top specification single beam and side-scan equipped Z-Boats, largely used by land survey and engineering firms or dedicated hydrographic survey operators as a full turnkey package including HYPACK® software

Waves breaking over sandy beaches are captured in countless tourist photos. But enormous waves breaking deep in the ocean are seldom seen, although they play a crucial role in long-term climate cycles.
A University of Washington study for the first time recorded such a wave breaking in a key bottleneck for circulation in the world’s largest ocean. The study was published online this month in the journal Geophysical Research Letters.
