Millions of tonnes of plastic wind up in the ocean every year, killing plants and animals. That’s why companies around the world have developed novel devices to help reduce the ocean plastic problem.

We’ve supersized our capacity to ship stuff across the seas. As our global supply chains grow, what can we gather from the junk that washes up on shore?

Island states are often dependent on expensive imported fossil fuels for their power. Ocean thermal energy conversion plants could provide constant power – if technical issues can be overcome.

Virologists have identified 5,504 new virus species floating in ocean water samples. The viruses were found using a machine learning algorithm to study 35,000 water samples from all over the globe, reports Vishwam Sankaran for the Independent.

One man’s trash is an octopus’ treasure. A group of researchers from Italy and Brazil wanted to take a closer at how deep-sea octopuses interact with trash that makes its way to the ocean after being discarded by humans.

All manner of croaks, chirps, and deep trombone moans permeate Earth's waters, just like the cacophony of sounds that fill its forest air. For example, reefs are surprisingly noisy places, and many of the noisemakers are fish.

About 51 trillion microplastics are floating in the surface waters of oceans around the world. Originating from various types of plastics, these tiny fragments (less than 5 millimeters in length) pollute natural ecosystems. Hundreds of studies have surveyed plastic debris on the surface or near surface of the ocean. However, these studies only "scratch the surface," and do not provide a complete inventory of what's lurking beneath.

A study ties the warming trend to human emissions of greenhouse gases from the burning of fossil fuels.

Researchers from the University of Adelaide have found that the way fish interact in groups is being upset by ocean acidification and global warming.

Hermit crabs are finding their way into discarded tires in the ocean -- and they can't get out, a new study from Hirosaki University found. The concave interior of a car tire can trap hermit crabs that go there in search of food and shelter. The study refers to this phenomenon -- when marine animals get caught in human litter, such as fishing nets -- as "ghost fishing."

Just as with planetary or molecular systems, mathematical laws can be found that accurately describe and allow for predictions in chaotically dynamic ecosystems too – at least, if we zoom out enough.

Here's how engineers got the car-sized Benthic Rover II to roam the seafloor 13,000 feet deep without immediately breaking down.

Phil Cruver, former CEO of Catalina Sea Ranch, explains why he’s now focusing his attentions on producing food-grade seaweed in the Caribbean, using a unique, submersible system.

It's been nearly a decade since Boyan Slat announced at age 18 that he had a plan to rid the world's oceans of plastic. Slat, now 27, is a Dutch inventor and the founder of the Ocean Cleanup, a nonprofit that aims to remove 90% of floating ocean plastic by 2040.

At the Goodwood festival of speed near Chichester, the crowds gathered at the hill-climb circuit to watch the world’s fastest cars roar past, as they do every year. But not far from the high-octane action, there was a new, and quieter, attraction: a display of the latest electric vehicles, from the £28,000 Mini Electric to the £2m Lotus Evija hypercar. Even here, at one of the biggest events in Britain’s petrolhead calendar, it’s clear the days of the internal combustion engine are numbered.

Keder consists of two parts: a core and fabric. The core is made from extruded PVC, or another elastic material, to allow flexibility.

Tasmanian right-to-information documents have revealed the extent that salmon producers go to protect their harvest against seals, with the use of more than 75,000 seal crackers and almost 4,000 bean bag shots recorded over a three-year period by the industry.

The Pacific footballfish, which was featured in Pixar’s Finding Nemo, was found in perfectly preserved condition

The Chagos Archipelago is one of the most remote, seemingly idyllic places on Earth. Coconut-covered sandy beaches with incredible bird life rim tropical islands in the Indian Ocean, hundreds of miles from any continent. Just below the waves, coral reefs stretch for miles along an underwater mountain chain.

Prize-winning author Richard Flanagan slams the Tasmanian salmon industry, describing it as disastrous for the environment, with overstated health benefits — and alleging the public had not been told the extent of the expansion plans for fish farms around the state.
