NASA and CNES satellite detects 19.7 meter waves in the North Pacific in 2024, an ocean record in the open sea

A satellite, the result of a partnership between NASA and Centro Nacional of Estudos Espaciais of França (CNES), recorded the largest ocean waves ever observed from space in the open sea. The phenomenon occurred at Oceano Pacífico Norte in 2024. Measurements were taken during the Eddie storm, revealing formations with an average height equivalent to a six-story building. Essa discovery represents a milestone for oceanography.

The measurement, carried out on December 21 by the SWOT satellite (Topografia of Água Superficial and Oceanos), marked a significant advance. Este equipment was designed to map rivers, lakes and oceans with remarkable accuracy. The technology allowed researchers to observe details of the sea surface that were otherwise difficult to capture. Até then, older satellites did not offer such detail capability.

Satélite SWOT revolutionizes ocean monitoring

The SWOT satellite represents a crucial milestone in ocean observation. Ele fundamentally differs from previous space missions. Early Satélites analyzed only small swaths of the sea surface. SWOT has the unique ability to produce comprehensive two-dimensional images of water. Essa advanced feature allows scientists to go far beyond simply measuring wave height. Eles can now accurately determine the propagation direction, the length of each wave and the general dynamic behavior during major weather events.

The research, which used this groundbreaking data, was led by oceanographer Fabrice Ardhuin. Ele acts on Laboratório of Oceanografia Física and Espacial, on França. The detailed study was published in the renowned scientific journal Proceedings of the National Academy of Sciences of the United States of America. The unprecedented data collected by the satellite thus offers an essential new perspective on the complex dynamics of the seas and their interactions with storms. The accuracy of SWOT is the result of considerable technological investment. Ele was developed by an international consortium. Seu primary objective is to provide a deeper understanding of the planet’s water resources. The ability to observe the ocean in two dimensions is especially valuable. Isso allows researchers to map currents and turbulence. Tais information is crucial for climate models and ocean predictions. The collaboration between NASA and CNES demonstrates the importance of global efforts in science. The satellite constantly monitors Terra. Ele collects information vital to understanding natural systems.

Definição of record waves and precise measurements

The researchers involved in the study emphasize that the value of 19.7 meters represents the “significant height” of the waves. Este technical term, widely used in oceanography, corresponds to the average of the third of the largest formations recorded throughout a storm. It is a standardized and robust method. Ele is employed to assess sea intensity in extreme conditions and for maritime safety purposes.

It is important to note that isolated waves may have exceeded 30 meters in height during the storm’s peak. Contudo, these momentary spikes are not included in the official record. The scientific methodology prioritizes the general behavior of the ocean. Ela does not focus on specific occurrences caused by the violence specific to one moment of the storm. Este precise measurement episode gained prominence in the scientific community. Previous generation Satélitess were rarely able to record such high waves with the same accuracy and detail. Desde In the 1990s, several space missions have monitored the behavior of the oceans. However, few were lucky enough or able to pass right through the center of the most intense storms at the crucial moment. The SWOT satellite, in the specific case of the Eddie storm, demonstrated its superiority. Ele precisely crossed the most violent region of the climate system. Essa strategic coincidence provided researchers with unprecedented and valuable observations about ocean movement under conditions considered extreme. The ability to capture this data in the exact location and at the right time is what sets SWOT apart.

SWOT satellite Capacidades and observations

The SWOT satellite, with its advanced technology, has a series of measurement capabilities crucial for modern oceanography. Diferente than previous equipment, it offers a much more complete and detailed view of the ocean surface. Suas tools allow scientists to analyze waves from multiple angles, providing an in-depth understanding of their formation and propagation.

Key features and measurements performed by the SWOT satellite include:
• Altura of waves: Precisão in recording the vertical magnitude of oceanic formations.
• Propagation Direção: Rastreamento exact of the direction in which waves move across the sea surface.
• Comprimento of waves: detailed Medição of the distance between consecutive crests, essential for understanding the energy transported.
• Comportamento during storms: Análise of the ocean’s dynamic response to extreme weather events.
• Two-dimensional surface Variações: Detailed Mapeamento of aquatic topography, revealing complex patterns.

Esses integrated data is essential for building more realistic models of ocean behavior. The ability to provide two-dimensional images also allows observation of currents and turbulence. Tais information is vital for improving climate models and global maritime forecasts. The collaboration between NASA and CNES to develop SWOT demonstrates the global commitment to ocean science.

Tempestade Eddie and the swell phenomenon

Storm Eddie was categorized as a high-intensity extratropical cyclone. Ela formed and performed under Pacífico Norte, demonstrating considerable strength. Além was the generator of giant waves, the system caused severe storm surges along extensive coastal areas. Houve records of damage in several locations on the American continent. Essa’s influence extended geographically, encompassing regions ranging from Canadá to Peru. The waves generated by Eddie, remarkably, demonstrated an exceptional propagation capacity. Elas continued to move and travel long distances even after the intensity of the winds that gave rise to them in the storm decreased.

Este particular phenomenon is known scientifically as waves. Ele occurs when ocean energy, once generated by a strong wind system, persists and travels great distances. Isso happens even after the original weather system that produced them weakens or dissipates. Scientists carried out precise calculations. Eles estimate that these ripples traveled approximately 24 thousand kilometers. The impressive route included crossing the vast Oceano Pacífico. Posteriormente, the waves passed through Drake’s iconic Passagem, located between Sul’s América and Antártica. Finalmente, they reached parts of Atlântico Tropical weeks after its origin, demonstrating the vast range capability.

Agência Espacial Europeia (ESA) takes an interesting perspective when considering seas. Ela describes them as true “messengers” of storms. Essa analogy underlines the importance of the phenomenon. Wave energy has the potential to cross entire oceans. Isso could result in significant impacts in very distant regions. Mesmo When the original climate system does not directly reach the continent, its waves can generate effects. Praias Remote and coastal ecosystems may be affected. Tal power transmission capability highlights the interconnectedness of global climate and ocean systems. Monitoring these waves is, therefore, essential for understanding meteorological and maritime phenomena on a planetary scale.

Avanços in ocean science and maritime risks

The unprecedented and highly detailed data provided by the SWOT satellite has made important contributions to global ocean research. Eles allowed scientists to perform a critical review of existing mathematical models. Esses models are fundamental for calculating the energy transported by ocean waves. Anteriormente, some old estimates, based on less advanced measurement technologies, indicated much higher values. Tais values ​​were inconsistent with what was actually observed and accurately measured by the satellite.

With the availability of significantly more detailed and accurate measurements, researchers are now in a position to develop more realistic and accurate computer simulations. This improvement in modeling is expected to substantially improve maritime forecasts. Consequentemente, the safety of vessels of all types, including cargo and fishing vessels, during severe storms can be optimized. The continuous and improved monitoring provided by SWOT is vital. Large Ondas pose considerable risks. Eles directly affect the integrity of cargo ships, oil platforms, the stability of submarine cables and other essential infrastructure installed at sea. More accurate and real-time Informações helps port authorities and shipping companies in defining safer routes and operations, minimizing losses and accidents.

Researchers are also actively investigating a possible connection between extreme events, like storm Eddie, and the broader picture of global climate change. Embora Although there is no definitive answer or absolute consensus, the hypothesis under study suggests that warmer oceans tend to provide a greater amount of energy. Essa additional energy can, in turn, fuel and intensify storm formation. Fatores additional natural features, such as complex sea currents, diverse underwater relief and predominant wind direction, also exert a direct and significant influence on the formation of giant waves. The record made by SWOT, with its unprecedented capacity for detail, highlights an important fact: our planet’s oceans still contain phenomena that are little understood and many secrets yet to be revealed. The most advanced technologies are now allowing remote and previously unreachable areas of the planet to reveal details that previously completely escaped conventional measurements and observations. Este is a constantly evolving field of research, with the potential to transform our relationship with the marine environment.
