How GPS Trackers and Drones Help Locate Floating Debris

An estimated 600,000 tons of abandoned fishing gear ends up in the oceans every year. According to the United Nations, some 380,000 marine mammals are killed each year, either by ingesting this fishing gear or being caught in it. Mary T. Crowly of the Ocean Voyages Institute describes how GPS trackers are being used to mark the ghost nets. An estimated 600,000 tons of abandoned fishing gear ends up in the oceans every year.

Consequence of Arctic Sea Ice Melt: Changing Weather at the Equator

Two researchers present evidence in the journal Proceedings of the National Academy of Sciences, a peer-reviewed multidisciplinary scientific journal that publishes original research, scientific reviews, commentaries, and letters, that the accelerating melt of Arctic sea ice is linked to weather patterns near the equator in the Pacific Ocean. Charles Kennel, a physicist and the former director of Scripps Institution of Oceanography at UC San Diego, and colleague Elena Yulaeva said there is strong evidence that the ice melt sets a chain of events in motion that sends cold air equatorward in the upper atmosphere. The two used computer analysis of historical data... (read more)

Silicon Sensing’s Technology Supports Autonomous Mayflower Voyage

Two Silicon Sensing Systems ultra-precise AMU30 inertial measurement units (IMUs) will provide critical navigation data to the autopilot capability for the Mayflower Autonomous Ship (MAS) throughout her milestone transatlantic voyage this autumn. Setting sail this September, the 15-meter long, 5-ton MAS400 will repeat the Mayflower’s original epic voyage made 400 years ago. Led by marine research organization ProMare and powered by IBM, she will sail from Plymouth, England to Plymouth Massachusetts, USA. Instead of a captain and crew, she will use computer vision, machine learning, cutting-edge technologies and sensors to navigate and detect hazards.   Silicon Sensing’s AMU30 devices will form...

How to Derive Shallow-water Bathymetry Measurements from Satellites

TCarta Marine, a provider of marine geospatial products, is commercializing a new technique to derive highly accurate shallow-water bathymetry measurements from NASA’s ICESat-2 satellite data. The new methodology is being developed with funding from the National Science Foundation (NSF). In 2018, NSF awarded the company a Phase 1 Small Business Innovation Research (SBIR) grant to commercialize new satellite-derived bathymetric (SDB) measurement technologies. Referred to as Project Trident, the research focused on leveraging Artificial Intelligence (AI) – machine learning and computer vision – to determine shallow-water seafloor depth in variable water conditions. Bathymetric Data Extraction Tool “As participants in NASA’s Applied Users... (read more)

Jamie McMichael-Phillips Appointed Director of The Nippon Foundation-GEBCO Seabed 2030 Project

Jamie McMichael-Phillips, the new director of The Nippon Foundation-GEBCO Seabed 2030 Project, has now taken up his position in leading one of the most challenging projects of the next decade, the mapping of the entire ocean floor by the year 2030. The announcement of his appointment was made at a conference held at the Royal Society in London, in October. Entitled ‘From Vision to Action’, the meeting, which brought together some of the world’s leading scientists and maritime organizations, was convened to mark the progress made in the two years since Seabed 2030 was launched, and to look ahead to...

'Clownfish Nemo Won’t Be Able to Save Himself'

The beloved anemone fish popularized by the movies 'Finding Nemo' and 'Finding Dory' does not have the genetic capacity to adapt to rapid changes in its environment, according to a new study by France’s National Centre for Scientific Research (CNRS), the Woods Hole Oceanographic Institution (WHOI) and partners. Their findings were published in the journal 'Ecology Letters'. An international team of researchers monitored clownfish in the lagoons of Kimbe Bay – a biodiversity hotspot in Papua New Guinea – for more than a decade, reports Eurasia Review, an independent journal and think tank that provides a venue for analysts and experts...

Researchers Find Japanese WWII Aircraft Carrier Destroyed in the Battle of Midway

Video Included
Deep-sea explorers scouring the world’s oceans for sunken Second World War ships have uncovered the wreck of a Japanese aircraft carrier destroyed in the Battle of Midway. Fought on June 1942, the clash saw US aircraft carriers ambush their Japanese enemies and sink all four opposing Imperial Navy (IJN) flattops, thanks partly to intelligence gained through intercepted communications. The crew of the research vessel Petrel, in conjunction with the US Navy, revealed on Friday that it had found the Japanese carrier Kaga 350 miles (560 km) northwest of Midway Island, lying at a depth of 5.4km. This week, the crew... (read more)
