“Frozen Waves”

Photographer Jan Erik Waider is a master of capturing incredible landscape imagery. In these videos, he uses a drone to film waves in the Baltic Sea gently undulating polygonal slabs of ice on the ocean surface. The interplay of light, color, and motion looks almost surreal, but nature is better than we credit at making imagery too good to look away from. (Video and image credit: J.

Testing Structures Against Hurricane Storm Surge

When hurricanes hit coasts, they bring with them incredible storm surge, which puts buildings right in the middle of ocean waves. To understand how to better protect against those conditions, engineers use facilities like the Directional Wave Basin to create smaller-scale versions of hurricanes. In this Practical Engineering video, Grady visited during a test that compared two identical one-third-scale houses subjected to the same storm conditions–except that one house had an additional foot (3ft at real-scale) of elevation. The results are pretty spectacular.

This isn’t a short video, but it’s well-worth a watch. I think Grady does a great job of explaining why engineers need (admittedly) expensive facilities like this one to help guide both engineering and regulatory decisions. (Video and image credit: Practical Engineering)

Radiant Waves

Photographer Kevin Krautgartner captures the powerful waves of Western Australia from above. His latest series, Waves | Ocean Forces, features luminous turquoise waves, crystalline foam, and brilliant beaches. I could delight in staring at them for hours. Fortunately, he sells prints on his website! (Image credit: K. Krautgartner; via Colossal)

In 1939, Carl-Gustaf Rossby described the large ocean waves that move east to west. #Poetry #Science #History #Oceanography #OceanWaves #Rossby (https://sharpgiving.com/Sharp/thebookofscience/items/p1939c.html)

A Rough Day

Winds from the north made for wild conditions at Nazaré in Portugal. Photographer Ben Thouard caught these crashing waves in the late afternoon, when the low sun angle illuminated the spray of the surf. Every year teratons of salt and biomass move from the ocean to the atmosphere, much of it through turbulent wave action driven by the wind. Here, the wind rips droplets off of wave crests, but smaller droplets reach the atmosphere when bubbles–trapped underwater by crashing waves–reach the surface and burst. (Image credit: B.

So I pulled the M-Audio thingy, turned on MainStage and played a bass line in D (pentatonic). Bounced between keys and G&L Fretless. Ready to go. Logic on, new, tempo, tempo, 128, no, 132 bpm.

Play something busier than the keyboard riff. Becomes a 16 bar phrase. D-C-D-E/F bounce.

Spend an hour playing with the rhythm tracks. Making beats? I wouldn't presume.

Play a chorus for first and last 16 bars. Improvise over the middle.

Waves Over Sand Ripples

Look beneath the waves on a beach or in a bay, and you’ll find ripples in the sand. Passing waves shape these sandforms and can even build them to heights that require dredging to keep waterways passable to large ships. To better understand how the sand interacts with the flow, researchers build computer models that couple the flow of the water with the behavior of individual sand grains. One recent study found that sand grains experienced the most shear stress as the flow first accelerates and then again when a vortex forms near the crest of the ripple. (Image credit: D.

Satellites Reveal The Power Of Ocean Swell

“During recent storms, satellites recorded ocean waves averaging nearly 20 metres high – the largest ever measured from space. Moreover, satellite data now reveal that ocean swells act as storm ‘messengers’ - even though a storm may never make landfall, its swell can travel vast distances and bring destructive energy to distant coastlines...
This record merges data from satellites such as #SARAL, #Jason3, #Copernicus #Sentinel 3A and 3B, Copernicus #Sentinel6 Michael Freilich, #CryoSat and #CFOSAT…”

The ocean never rests.
Waves rise, crash, and dissolve against the rugged shoreline — a timeless rhythm of motion and power. This black and white photograph captures that fleeting energy in stark contrast and texture.

Predicting Sea States

Transferring cargo between ships and landing aircraft on carriers requires predicting how the waves will behave for the next few minutes. That’s a notoriously difficult task for several reasons: rough seas can hide a ship radar’s view and the inherent nonlinearity of ocean waves means that they can occasionally coalesce unexpectedly large (“rogue“) waves, seemingly from nowhere.

A new study describes a technique for improving sea state predictions. In their model, the team first use multiple radar returns to average out gaps in the current wave state data, then feed that interpolated data into a prediction algorithm that includes nonlinearities up to the third-order. The results, they found, gave far better predictions than current techniques, some of which had errors 3 times as high. (Image credit: R. Ding; research credit: J. Yao et al.; via APS News)

Rip Currents and Hurricanes

When it comes to the beach, looks can be deceiving. That calm-looking water to the side of big crashing waves may actually be a rip current that carries water back out to the ocean. Rip currents are a result of conservation of mass; just as waves carry water to the shore, something has to carry that incoming water back out to the ocean. Depending on the local topography, that outflow could be below the water surface, creating an undertow, or along the surface, as a rip current.

Even when far offshore, hurricanes can trigger unexpected and strong rip currents, largely because they create bigger waves that travel shoreward. Those waves can also change the depth and layout of the underwater shoreline, potentially exacerbating rip currents.

For more on rip currents, including the latest guidance on how to escape one, check out this article. (Image credit: A. Marlowe; via SciAm)
