Underwater Noise Monitoring in the North Sea

Jomopans Project to Monitor Continuous Sound
Sound is of vital importance for marine animals. Eleven institutes from the countries bordering the North Sea have joined forces in the Jomopans project to implement a novel monitoring strategy for underwater sound. Due to the growth of human activities in the sea, sound pollution is a growing concern for marine environmental managers. High levels of anthropogenic noise disturb animals, but the integrated impact of noise on the marine ecosystem is largely unknown. In the Joint Monitoring Programme of Ambient Noise in the North Sea (Jomopans) project, measurements at sea are combined with noise maps from numerical modeling to assess the quantitative levels of sound at sea.

Deepwater Turret Mooring Monitoring Offshore Mozambique

Mooring solutions supplier, SOFEC, Inc., has selected BMT and Sonardyne Inc., under their teaming agreement, to supply an innovative mooring monitoring system (MMS) for a major new deepwater development. The new system will involve monitoring of the turret mooring system on a new-build floating liquefied natural gas (FLNG) facility being built in South Korea for ENI’s Coral South project offshore Mozambique. With water depths ranging from 1,500-2,300 meters, SOFEC, a MODEC Group company, wanted to integrate a robust and reliable MMS to complement their market leading turret mooring solution. Station-keeping Turret Monitoring System Above the waterline, BMT will supply the station-keeping... (read more)

Falcon Flies In Canada's First Nation Waters

The University of Victoria has engaged Ocean Dynamics to deploy a Saab Seaeye Falcon robotic vehicle for the inspection of instrumentation platforms monitoring the ocean around Canada’s north-west coast, particularly in First Nation coastal waters. A total of 50 instrumentation platforms, together with six observatories are plugged into over 900 kilometres of fibre-optic cable on the seafloor giving internet access to marine scientists and coastal communities to enable evidence-based decision-making on ocean management, disaster mitigation, and environmental protection. The University’s world-leading Ocean Networks Canada undertaking was launched in 2006 with the first “wired” seafloor observatory. Since then, community observatories have... (read more)

Cornish Marine Contingent Plans to Make Waves at Seawork 2019

Cornwall will be represented by five innovative companies at Europe’s largest marine exhibition, with the help of financial support from the Marine-i project. Part funded by the European Regional Development Fund, Marine-i is designed to help the marine tech sector in Cornwall and the Isles of Scilly grow through harnessing the full potential of research and innovation. Taking place in Southampton from 11th to 13th June, Seawork is Europe’s largest international marine and workboat exhibition. It will be attended by 8,000 high-caliber marine professionals from 70 countries, 40% of whom are directors or owners. It is, therefore, the perfect opportunity... (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.
