"HYPACK Playback with Multibeam Auto Processing" webinar

Wednesday, July 15, 3:00–4:00 PM (ET)

This virtual symposium will focus on HYPACK/HYSWEEP Survey and Multibeam Auto Processing and the methodology for setting up HYPACK to playback Multibeam files for training or demonstration purposes - which can reduce workload and improve efficiency.

Caryn Zacharias, Technical Support, HYPACK

"Sidescan Data – Making the Perfect Mosaic in SonarWiz" webinar

Wednesday, July 29, 3:00 p.m. – 4:00 p.m. (ET)  

The session will focus on sidescan data, with the objective of mosaicking the data to create a perfect image. We’ll go over some of the tools and features in SonarWiz, showing off the tools and different ways to enhance your sidescan data. We’ll finish the session by creating a 3D mosaic using a DTM model, and a way to create a surface using the altitude from the data.

Harold Orlinsky, General Manager, Chesapeake Technology, Inc.

September 20 - 23, 2021 in San Diego, CA

Co-presented by MTS and IEEE Oceanic Engineering Society , this premiere event brings together global marine technologists, engineers, students, government officials, lawyers, and advocates to learn and experience cutting-edge technologies in the marine science, learn about latest research, and more.

Program Exploring Ammonia as a Maritime Fuel Funded for Norway in 2021

A program is commencing to explore the use of ammonia as a maritime fuel. Underwritten with a $2.1 million grant from the Norwegian Research Council through the DEMO 2000 program, the project will be led by Wartsila’s technology group in cooperation with Knutsen OAS Shipping AS and Repsol, as well as with the Sustainable Energy Catapult Centre.

There has been a growing interest in the maritime industry in ammonia, which is seen as a promising carbon-free fuel for marine applications. Several research initiatives have been launched into ammonia as a marine fuel as the industry works to meet the International Maritime Organization’s goal of reducing greenhouse gas emissions from shipping by at least 50 percent by 2050.

Video: New Robotic LARS Put to the Test

Israeli technology startup Sealartec reports it has conducted full sea trials for its new robotic launch and recovery system (LARS) over recent weeks off Israel's northern shores. 

In a series of tests, Sealartec demonstrated its system's capability to perform precise and fully autonomous launch and recovery of an unmanned surface vessel (USV). The recovered boat was a 5-meter deep-v monohull classic design, autonomous vehicle. Sea conditions during trials were as high as sea state 4, with gusting winds.

Climate Change May Cause Extreme Waves in Arctic

Extreme ocean surface waves with a devastating impact on coastal communities and infrastructure in the Arctic may become larger due to climate change, according to a new study.

The new research projects the annual maximum wave height will get up to two to three times higher than it is now along coastlines in areas of the Arctic such as along the Beaufort Sea. The new study in AGU's Journal of Geophysical Research: Oceans suggests waves could get up to 2 meters (6.6 feet) higher than current wave heights by the end of the century.

Scripps Institution of Oceanography: 3D-printed Coral Are Natural Producers of Biofuels

Researchers at the Scripps Institution of Oceanography and the Jacobs School of Engineering at UC San Diego, alongside the University of Cambridge, UK, have 3D printed coral-like structures capable of growing dense microscopic algae populations. The work is aimed at the development of compact, efficient bioreactors for producing algae-based biofuels and could lead to a better understanding of the coral-algae relationship, with the hopes of establishing techniques to repair and restore reefs.

Author Daniel Wangpraseurt explained, “Corals are one of the most efficient organisms at using, capturing, and converting light to generate energy,” even in extreme environments with light fluctuation and limited space to grow. Inspired by corals, the goal was to develop productive techniques for growing microalgae as a form of sustainable energy."

Marine Propulsion Systems Market to Hit $11 Billion by 2026, Says Global Market Insights, Inc.

Posted by: Oil & Gas 360

The  Marine Propulsion Systems market  is set to cross USD 11 billion by 2026, as reported in the latest study by Global Market Insights, Inc. Rising disposable income coupled with expansion of global seaborne trade is set to drive the product installation. Ongoing R&D investments accompanied by technological advancement in the marine propulsion systems and its application will complement marine propulsion systems industry size..

The global market is set to undergo significant growth quartering the forecast timeline owing to 80% of all international trade by volume being accounted by the maritime transport. Rise in global population and growing demand from developing economies will stimulate the product installation. Moreover, advancements in design & technology, swift shift from traditional fuel to low sulphur oil and stringent government directives to adopt clean fuel is set to drive the demand for systems supporting LSFO, LNG and hybrid fuel.

What's at the Bottom of the Sea? A Fifth of the World's Ocean Floor Has Now Been Mapped

Posted by: Euro News

A project is underway to map out the full surface area of the global ocean floor by 2030. So far, nearly a fifth has been mapped, which is equivalent to an area twice the size of Australia.

Seabed 2030   was launched in 2017 by the Japanese Nippon Foundation and non-profit GEBCO, to help scientists understand the impact oceans have on the earth’s climate. Researchers have announced that a significant proportion is now complete, accounting for 14.5 million square kilometres of new bathymetric data. Bathymetry is the measurement of depth of water in oceans, seas, or lakes. As a result of hard work, coverage of the seabed has risen from 15 per cent to 19 per cent in the last year. Only six per cent of the ocean floor had been mapped when they launched three years ago.

An Innovative Anchor That Could Help Floating Offshore Wind Take Hold

Posted by: Energy News Network

Inspired by mantis shrimp, a team of researchers from Purdue University and clean energy startups hope to use 3D printing to create cheaper and more environmentally friendly anchors for floating offshore wind turbines. 

Floating turbines are  an emerging option  for generating power in deeper water further offshore than wind turbines fixed on the seafloor. While there are relatively few large-scale floating wind farms in operation, experts hope floating turbines could greatly expand the scope of offshore wind, generating power more efficiently where winds are stronger, and where turbines are less visible from land.

First Direct Evidence of Ocean Mixing Across the Gulf Stream

New research provides the first direct evidence for the Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to Newfoundland and along the western coast of Europe.

The multi-institutional study led by a University of Maryland researcher revealed that churning along the edges of the Gulf Stream across areas as small as a kilometer could be a leading source of ocean mixing between the waters on either side of the current. The study was published in the Proceedings of the National Academy of Sciences on July 6, 2020.
