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)

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)

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)
