Study Records Zooplankton Transporting Microplastics to the Deep Sea
and food concentrations. In other words: beads, fibers and fragments all moved through the gut at similar speeds, and feeding conditions did not significantly slow or accelerate plastic throughput. By combining these measurements with realistic estimates of copepod abundance in the western English Channel – one of the most highly studied bodies of water in the world - the team calculated that copepods could be driving microplastic fluxes on the order of about 271 particles per cubic meter of seawater per day, in that region.Up to now, many large-scale computer models of microplastic transport
UKHO Partners with Shom to Launch International S-100 Sea Trials Program
deployed aboard ferry, defense and commercial shipping vessels. S-100 sea trials underway Since August 2025, the UKHO has been working with Raymarine and DFDS to deploy an S-100 ECDIS aboard the Stena Vinga ferry for navigation from Portsmouth on the south coast of England, across the English Channel to St. Helier in Jersey. These initial trials are being supported by Portsmouth International Port and Ports of Jersey, who are providing new, high-fidelity bathymetric data to create S-100 data layers. The international cross-border trial will follow a route from St. Helier to Saint-Malo
Billions in Lost Treasure: How Modern Technology Is Revealing Hidden Riches from the Depths!
hidden here as well.The Atlantic Ocean off of the east coast of the United States has long been known for its treasure hunting activity. Explorers come to search wrecked ships like the SS Central America and merchant vessels lost during World War II that have come aground there. Additionally English Channel and Mediterranean Sea waters were heavily trafficked by merchant and military vessels for centuries - both providing prime hunting grounds.Estimating the Total Treasure Recovered Since WWIIWhile it is impossible to precisely determine the total treasure recovered since World War II, treasure
How Do You Build Tunnels and Bridges Underwater?
through the ground, removing the excavated material out behind it. Done with care, this method can successfully build a tunnel through the ground beneath a body of water that can then be lined and reinforced.Engineers used this method to build the Chunnel, for instance, a railway tunnel beneath the English Channel that connects England and France.While modern machinery is quite advanced, this method of construction started about 200 years ago with the tunneling shield. Initially, these were temporary support structures that provided a safe space from which workers could excavate. New temporary structures
Prysmian Commissions Inter-Array Cable System at French Offshore Wind Farm
Prysmian Group has commissioned the inter-array cable system for the Fécamp offshore wind farm, located in the English Channel, offshore France.The Fécamp offshore wind farm is composed of 71 wind turbines with a total capacity of nearly 500MW.It will be able to generate clean electricity equivalent to the power needs of over 770,000 people.Prysmian had secured this project in 2020 with a contract awarded by EDF Renewables and its partners.Asso.subsea was contracted by Prysmian Group to execute the seabed preparation, installation and protection works for the cables. The company completed
MTR100: Subsea Batteries
years ago to reduce emissions and costs and boost operational flexibility. The self-contained, battery-powered ROV can operate for extended periods of time without being recovered to surface.RS Aqua’s batteries were recently put on SEABER’s YUCO micro-ROV when it successfully crossed the English Channel in less than eight hours. Credit: SEABER FR.Earlier this year, Verlume’s seabed battery intelligent energy storage system, Halo, was deployed as part of the Renewables for Subsea Power project in Scotland. The system enables AUVs to dock, recharge batteries, upload data and receive new
First Underwater Drone Crossing of the English Channel
Earlier this year, the YUCO became the first micro–Autonomous Underwater Vehicle (AUV) to successfully cross the English Channel from Folkestone, England, to Wissant, France. The crossing, a partnership between RS Aqua and SEABER, took less than 8 hours.The AUV measures just under one meter long and weighs 10 kg, small but mighty enough to battle its way through the highly variable weather conditions and strong currents in the Channel – also considered to be one of the busiest shipping lanes in the world.To maintain accurate navigation and keep the mission on track, the YUCO
Kremlin’s Threat to Interfere with Undersea Data Cables Should Be Taken Seriously
, places that are more vulnerable and where the impact would be more extensive. This includes sites where several crucial cables could be attacked at the same time. These are known as “chokepoints”.For instance, several important cables surface in the port of Marseilles – and the English channel and the Red Sea have a high density of cables. Also, island states, such as Ireland, are more vulnerable because they do not have terrestrial connections as backup.So Medvedev’s threat should be taken seriously, but should not be blown out of proportion.What’s behind the threat?Once
New Sensors Expected to Reduce Illegal Immigration Across English Channel
French and British authorities have ordered infrared panoramic detection systems from French company HGH to help reduce illegal immigration across the English Channel.The two countries have previously signed a “smart border” agreement worth 72.2 million euros for the period 2022-2023. The aim is to use advanced technologies to secure the coastline and prevent people drowning onboard makeshift boats.HGH will provide its SPYNEL solutions which allow for permanent and continuous surveillance. They will be used in addition to the surveillance provided by patrols, drones and planes already used
