With the aid of arms control technology and artificial intelligence, a team of scientists at Cardiff University's School of Mathematics has developed a method that uses underwater microphones to provide early warnings of potentially deadly tsunamis.

Much of the heat and carbon produced by humans is absorbed by the ocean. New research has shed light on the role that underwater waves play in moving that heat and carbon around our oceans, an important factor in predicting climate change.

Irish company OceanEnergy has already tested its oscillating water column generators at significant scale in Hawaii, and it's just signed on to a four-year project to test, validate and commercialize its biggest unit yet off Orkney, in Scotland.

The UniWave sea platform is an artificial blowhole that harvests energy from ocean waves. Independent analysis now predicts it'll create some of the cheapest renewable energy on the market – and some of the most reliable and predictable, as well.

A new class of elastic energy converters is emerging, with the ability to capture energy from a variety of different motions. The National Renewable Energy Laboratory is pushing to deploy them, first in a series of strange, bendy wave energy designs.

Sea Wave Energy Ltd has been working for more than a decade on an ultra-cheap floating wave energy device. With several prototypes tested, the company is promising capacities over 100 MW, with unheard-of energy cost figures under 1 cent per kWh. Hmm.

Wave Swell Energy's remarkable UniWave 200 is a sea platform that uses an artificial blowhole formation to create air pressure changes that drive a turbine and feed energy back to shore. After a year of testing, the company reports excellent results.

Researchers are reporting a record-setting new example of a phenomenon known as a rogue wave, with a four-story-tall behemoth that occurred off the coast of Canada confirmed as the most extreme ever measured.

Scientists have uncovered a new way tsunamis might be better predicted ahead of time, showing how the magnetic fields they generate can be detected before the massive, devastating waves make it to shore.

There are energy sources all over the place, if you know where to look. Researchers at CUHK have now designed new modular nanogenerators that can harvest energy from various different types of motion, such as ocean waves or a person's body movements.

In most surf parks, surfers ride artificially-generated waves down the length of an oblong pool. Unfortunately, such an arrangement limits the number of people who can rides the waves at once … which is where the 5 Waves system comes in.

Although seawalls certainly do protect coastal communities from storm surge waves, those walls can be unsightly, and restrict access to the water. A proposed new system gets around those problems, by doubling as a canopy when not serving storm duty.
