How Scientists Use Satellite-mounted Laser to Map Global Ocean Migration

A study published in the 12 December issue of Nature reports on the use of satellite-borne lidar to map the daily vertical migration of zooplankton across the world’s seas over the course of a decade. On Williams Yorktown Daily, a US-based news site, lead author Michael Behrenfeld of Oregon State University says, “What the LiDAR allowed us to do is sample these migrating animals on a global scale every 16 days for ten years. We’ve never had anywhere near that kind of global coverage to allow us to look at their behaviour, distribution, and abundance.” On the study were researchers from... (read more)

Danish Hydrographic Office Turns to GIS For Automated Maritime Charting

A Radical Update Was Needed

Denmark has challenging seascapes to map and chart. It has a rich history of nautical charting that dates back to the seventeenth century, and many of its navigational products for Greenland were created in the 1960s. When GPS started to gain prominence, a radical update was needed. Apart from its 42-mile land border with Germany, the peninsular country of Denmark, with its scores of bays, straits, and fjords, is surrounded almost entirely by the North and Baltic Seas. Denmark is also composed of more than 400 islands, including the Faroe Islands, located in the Atlantic Ocean between the United Kingdom... (read more)

Scientists Discover Roman Shipwreck Dating Back to Time of Jesus Christ

In October, a scientific team from the Balearic Institute of Maritime Archaeology Studies found a Roman cargo ship with jugs containing olive oil and perfectly preserved garum sauce, an ancient form of ketchup. Scientists have discovered the extremely large Roman shipwreck dating back to the time of Jesus Christ. The ship and its cargo could reveal new information about shipbuilding and trade during that time period. The sunken vessel was recently discovered off the coast of Greece, near Kefalonia Island, during a survey conducted by the Oceanus Network of the University of Patras, Greece. Sonar Equipment and Artificial Intelligence The... (read more)

In-mission Processor Allows Real-time Processing of HISAS Data

Hydroid, Inc., a subsidiary of Kongsberg Maritime and a leading manufacturer of marine robotic systems, has just announced it has integrated an in-mission processor on a REMUS 600 Unmanned Underwater Vehicle (UUV) with the KONGSBERG High-Resolution Interferometric Synthetic Aperture Sonar (HISAS) 2040 for a customer. By integrating the in-mission processing, the high-resolution images from the HISAS module can be quickly downloaded when the vehicle returns from its mission. Gap-filled Image HISAS 2040 provides up to 2cm by 2cm resolution across a 300-metre swath. When combined with the onboard EM2040, it provides a complete, gap-filled image. Synthetic aperture sonar uses algorithms... (read more)

Inspection and 3D Modelling Project at Galloper Offshore Windfarm Completed

Subsea technology specialist Rovco has completed an extensive ROV inspection contract. This circa £1 million contract has resulted in the completion of the baseline asset integrity survey at the newly constructed Galloper Offshore Wind Farm, a 353MW installed capacity wind farm which lies 30km off the coast of Suffolk, UK. The project, which was awarded by Innogy Renewables UK, began in September - with 24-hour ROV operations provided over a four-week period. Rovco deployed a Cougar XT ROV fitted with both 3D imaging sonar and their SubSLAM 3D technology to complete planned asset inspection activities. The project was performed from... (read more)
