AML Moving Vessel Profiler to Augment NSCC’s Seafloor Mapping Work

A newly acquired AML Moving Vessel Profiler (MVP) will help Nova Scotia Community College (NSCC) develop improved methods of mapping the seafloor. With its ability to conduct real-time, vertical profiles continuously and automatically, the MVP200 is expected to improve the efficiency and quality of data collection. Looking to add ground-truthing to the process of multibeam data acquisition, AML and NSCC are working together to integrate lights and a high-resolution camera to the tow body that houses the underway profiling system’s sound velocity (SV), conductivity-temperature-depth (CTD), or multiparameter instrumentation. Ground-truthing is a critical step in validating the seafloor characteristics for interpretation of... (read more)

Acoustics Specialist RTSYS Unveils Latest Versatile Micro-AUV

After years of development, French Acoustics specialist RTSYS has unveiled its latest versatile micro-AUV named NemoSens. Less than 1 metre long, and easy to carry and launch (less than 20 pounds including payload), NemoSens can host any kind of payload, be it a CTD probe, side-scan sonar or any other sensors. Thanks to an open LINUX architecture, it can be programmed from a ROS or MOOS interface to complete various kind of missions. Acoustic Beacons Its battery provides wide autonomy (up to 8 hours at 4 knots) with a speed range from 2 to 8 knots, and its robustness allows it... (read more)

CSA Completes Field Surveys Offshore Puerto Rico

CSA Ocean Sciences (CSA), under a subcontract to Jacobs, has announced the completion of a comprehensive environmental monitoring survey. The survey included physical, biological and chemical field sampling and data collection for 301(h) waiver demonstrations at the Aguadilla, Arecibo and Ponce Regional Wastewater Treatment Plant (RWWTP) outfalls offshore Puerto Rico for the Puerto Rico Aqueduct Authority (PRASA). Since 1999, CSA has been helping to evaluate compliance with receiving water quality standards and describe environmental conditions. Acoustic Doppler Current Profilers During this recent survey, CSA deployed and retrieved acoustic Doppler current profilers (ADCPs), a conductivity-temperature-depth (CTD) water profiler with ancillary sensors...

Valeport Launches Environmental Optical Sensors

Valeport, a British designer and manufacturer of hydrographic and oceanographic instruments, has launched two environmental optical sensors, a standalone turbidity sensor and a fluorometer. The first one of the new range, the Hyperion Turbidity, is the industry’s first standalone turbidity sensor that combines a Nephelometer and OBS readings in the same instrument. Created for inshore, coastal and oceanographic monitoring, this sensor delivers a minimum detection level of just 0.03 NTU (nephelometer) and can measure turbidity up to 6,000 NTU (OBS). The titanium housing, data output up to 16Hz and low power requirements ensure the sensor can be placed in situ for... (read more)

AML Oceanographic’s MVP200 Selected for Swedish Research Vessel

AML Oceanographic has announced that a Moving Vessel Profiler is being installed on one of the most modern research vessels in the world, the Swedish vessel 'RV Svea'. The newbuild Swedish vessel, owned by the Swedish University of Agricultural Sciences (SLU), will be used by the university and the Swedish Meteorological and Hydrological Institute (SMHI) for a wide variety of environmental surveys, from monitoring ocean acidification to assessing fish stock. By including a Moving Vessel Profiler (MVP), the scientists expect to gain a clearer understanding of the oceanographic dynamics encountered in the Baltic Sea, such as strong halocline layers and...

The Study of Mapping the Seafloor

What is the Difference Between a Bathymetry Chart and a Hydrographic Chart?

This article will immerse you into the deep water of Bathymetry. It explains in detail what a bathymetry map is, what it shows, what methods we use to collect the bathymetry data and last but not least, how to create a good quality bathymetry map. It will also cover the difference between a bathymetry chart and a hydrographic chart and the techniques our ancestors used in the past to collect and record depths. What is Bathymetry? Bathymetry is the study of mapping the seafloor. Bathymetric maps represent the ocean (sea) depth as a function of geographical coordinates, just as topographic maps... (read more)

Monitoring Real-time Hydrodynamic Changes from Coastal Platforms

Supporting Marine Renewable Energy (MRE) Research with Live Data from Buoy Networks

The nearshore and offshore regions running from the shallow coastal shelf to the intertidal zone are dramatic, tempestuous and extremely complex environments that offer the potential to reliably provide vast amounts of renewable energy to most coastal countries in one form or another. In order to harness this capability safely and efficiently, it is critical that we continue to expand our knowledge and understanding of the hydrodynamics of these environments. The ocean offers huge possibilities for generating electricity from waves and tides, and the UK is very well placed to exploit this form of electricity generation. Marine renewable energy is...

Research Vessel Technicians Meet their Peers at Woods Hole Oceanographic

Inmartech 2018

Research Vessel Marine Technicians from all over the world gathered in Woods Hole, MA, USA, on 16-18 October for their biannual Inmartech 2018 conference. Organised by the Woods Hole Oceanographic Institution (WHOI), the conference was the largest to date. David Fisichella, conference chair, said ‘As research vessel technicians, we work with scientists from all over the world on our vessels, but we don’t often get to collaborate with our peers from different countries. What makes Inmartech so special to me, is the ability to collaborate with people from around the world that I would not normally collaborate with.’ A selection... (read more)
