A team of Italian mathematicians has made significant progress in understanding the complex mathematics of ocean waves, particularly the stability and instability of Stokes waves, by proving when certain disturbances will destroy or preserve these waves, advancing our theoretical knowledge of fluid dynamics.
A study analyzing 18 years of data from the North Sea reveals that rogue waves, which can reach heights of 65 feet, are not just freak occurrences but are primarily caused by constructive interference of smaller waves, challenging previous theories and improving understanding of these dangerous ocean phenomena.
Seismic data has confirmed that ocean waves are shaking the Earth as storms become more ferocious due to global warming. The study highlights the impact of climate change on extreme weather events, with rising sea levels and increased storm intensity leading to stronger ocean waves that can generate seismic activity. This finding underscores the urgent need for climate action to mitigate the effects of warming on our planet.
Stormier seas and larger ocean swells, fueled by rising global temperatures, are causing increased wave energy that is pounding Earth's seafloor with more force, similar to tiny earthquakes. The North Atlantic Ocean has experienced the highest increase in wave energy, followed by the Southern Ocean around Antarctica. The intensifying waves, coupled with rising sea levels, pose a threat to coastal communities, erode land, and impact coastal infrastructure. The increase in wave activity is a result of stronger storms with intensified winds, driven by global warming. As temperatures continue to rise, wave activity is expected to intensify, exacerbating coastal risks.
A new study published in the journal Nature Communications reveals that global ocean wave energy has been increasing over the past four decades, coinciding with rising global temperatures and storminess. Seismic data collected from seismographic networks around the world show a significant and progressive increase in wave energy, with the North Atlantic experiencing the fastest intensification. The findings highlight the potential dangers of increasing wave heights for coastal communities, emphasizing the need for climate change mitigation and resilient coastal infrastructure.
A new study published in Nature Communications reveals that the Earth is experiencing an alarming increase in planet shaking due to intensifying ocean waves, which generate seismic waves. This increase in shaking correlates with rising global temperatures over the past four decades. Seismic activity is not solely caused by earthquakes but also by phenomena like erupting volcanoes, explosions, and meteor strikes. The incessant thrum of ocean waves, known as the global microseism, is the most pervasive background signal picked up by seismographs. The increase in planet shaking highlights the need to address climate change urgently and take action to mitigate its effects.
Seismic data collected over the past four decades shows that ocean waves are gaining strength as the planet warms due to global warming. The increase in wave energy is attributed to rising storminess caused by higher ocean swell and increasing global temperatures. The study found that globally averaged ocean wave energy has been increasing at a median rate of 0.27% per year since the late 20th century, with a faster increase of 0.35% per year since 2000. These findings highlight the intensification of storms and waves as a result of climate change, posing a warning for coastal communities and emphasizing the need for climate mitigation and coastal resilience strategies.
Seismic data collected over the past four decades shows that ocean waves are gaining strength and intensity as a result of global warming. The increase in wave energy coincides with rising global temperatures and storminess. Seismographic networks have observed the steady thrum created by storm-driven ocean waves, known as the global microseism. The study found that 79% of seismograph sites around the world showed significant and progressive increases in energy over the decades. The intensification of ocean waves poses a coastal warning, as it can lead to damaging waves, erosion, and infrastructure damage. Mitigating climate change and building resilience in coastal areas are crucial in addressing these impacts.
Albatrosses, known for their long-distance flights across the open ocean, can navigate the sky by listening to the very low-frequency sounds produced by ocean waves affected by wind conditions. Researchers have found that these infrasounds influence the birds' headings, causing them to change course when encountering loud infrasounds. While it's unclear how the birds utilize this information, it is evident that the infrasounds impact their behavior during flight.
Underwater waves, some as high as 500 meters, located deep below the ocean surface, play a crucial role in the ocean’s heat and carbon storage, according to new research. The study suggests that current climate models fail to accurately reflect the significance of these underwater phenomena, highlighting the need for a more accurate representation of small-scale turbulence in climate models and the installation of turbulence sensors on global observational arrays. The research also found that heat from the North Atlantic can reach the Antarctic much faster than previously thought, and turbulence within the ocean, particularly large underwater waves, plays an important role in the climate.
