New Study Finds Polyester Fibers Throughout the Arctic Ocean

The Arctic has long proven to be a barometer of the health of our planet. This remote part of the world faces unprecedented environmental assaults, as climate change and industrial chemicals threaten a way of life for Inuit and other Indigenous and northern communities that rely heavily on seafood and marine mammals for food.But who would have imagined that the clothes we wear might add to this onslaught? Evidence increasingly shows that tiny synthetic fibers are permeating the Arctic Ocean and finding their way into zooplankton, fish, seabirds and marine mammals.In a new study published in Nature Communicati

These Tiny Oceanic Creatures Are Essential to Tackling Climate Change

The ocean withdraws about one third of the CO₂ in the atmosphere, mitigating climate change and making life possible on Earth. An important share of this CO2 is removed thanks to phytoplankton, tiny marine creatures that use light to do photosynthesis, just as plants or trees on land. These cells fix CO2 to build up biomass and multiply, and take it down to the deep ocean when they die and sink. Phytoplankton are thus the basis of the marine food chain, and their productivity not only affects CO2 levels, but also fish catch and world economy.So why does phytoplankton go unnoticed to most of us, if

The total combined duration of the two surveys is estimated at around eight months.Stephan Midenet, CEO of Seabed Geosolutions this would be the company's sixth project in Brazil "a core OBN market."The company, which collects geophysical data on

Hydromea Launches LUMA X, Wireless Underwater Optical Modem

Hydromea launched a new patent-pending subsea wireless communication modem LUMA X. The LUMA X can beam data using light at up to 10 Mbit/s with a 120-degree cone. With that, the LUMA X enables real-time streaming of HD-quality video and 4K images wirelessly through water – allowing the operators of autonomous underwater vehicles to monitor its interventions from the comfort of its control rooms onshore.“The wide-angle beam gives subsea vehicles connecting via the LUMA X a lot of freedom of movement,” said Felix Schill, co-founder and CTO of Hydromea. “The small size of the

Saginaw Bay’s Marine Ecosystem Revival

“We are tied to the ocean. And when we go back to the sea, whether it is to sail or to watch – we are going back from whence we came”  – John F. KennedySaginaw Bay’s warm waters serve as nursery grounds for many fish species and support the fisheries of both Saginaw Bay and the main basin of Lake Huron. Historically, inner Saginaw Bay contained rock reefs that provided critical habitats, spawning grounds, and juvenile areas for many native fish species. This includes Walleye, Smallmouth Bass, and Suckers during the spring and Lake Whitefish, Cisco, Lake Trout, and

Japan to Release Fukushima's Contaminated Water Into the Sea

Nearly a decade after the Fukushima nuclear disaster, Japan's government has decided to release over one million tonnes of contaminated water into the sea, media reports said on Friday, with a formal announcement expected to be made later this month.The decision is expected to rankle neighboring countries like South Korea, which has already stepped up radiation tests of food from Japan, and further devastate the fishing industry in Fukushima that has battled against such a move for years.The disposal of contaminated water at the Fukushima Daiichi plant has been a longstanding problem for Japan as

TDI-Brooks Wraps Ivory Coast Offshore Survey for Total

TDI-Brooks International, in partnership with the French environmental firm Créocéan and Benthic Solutions, has completed an Environmental Baseline Studies (EBS) for the oil major Total offshore the Ivory Coast.The survey was conducted over offshore blocks CI-705 and CI-706, and included seawater sampling and profiling (CTD rosette) as well as plankton sampling (bongo net) at 7 stations, sediment sampling (Mega Box Core) at 45 stations, and live feed benthic video sled at 24 transects. The two blocks cover an area of around 3,200 sq km and include multi-target hydrocarbon prospects

Significant Dredge Monitoring Network for OSIL

Environmental monitoring systems manufacturer Ocean Scientific International Ltd (OSIL) said it has been awarded a contract for the international supply of a network of dredge monitoring buoys.The Tern buoy hull design incorporates a stainless steel sub frame with a moon pool for instrument protection, and its modular manufacture makes the buoy easy to ship and assemble on-site following delivery. The 12 buoys are set up to communicate via Iridium Short Burst Data (SBD) with an onboard Global System for Mobile Communications (GSM) option to further reduce operational costs when the buoys are moved
