Most strik­ ing advances have been in the fields of potassium-argon and rubidium-strontium dating. The most reliahle method of dating common rocks is from the potassium­ argon and rubidium-strontium ages of mica. Data exist which indicate that discordant uranium-lead ages of several minerals from the same geologic unit may in some cases prov-ide both the age of the rock formation and the time the rocks were altered.

  • The Origin of Deep Ocean Microseisms in the North Atlantic Ocean
    Proc. R. Soc. A (2008) 464, 777–793 doi:10.1098/rspa.2007.0277 Published online 8 January 2008 The origin of deep ocean microseisms in the North Atlantic Ocean 1, 2 1 BY SHARON KEDAR *,MICHAEL LONGUET-HIGGINS ,FRANK WEBB , 3 4 1 NICHOLAS GRAHAM ,ROBERT CLAYTON AND CATHLEEN JONES 1Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA 91109, USA 2Institute for Nonlinear Science, University of California, San Diego, La Jolla, CA 92093-0402, USA 3Hydrologic Research Center, San Diego, CA 92130-2069, USA 4Seismological Laboratory, California Institute of Technology, Pasadena, CA 91125-2100, USA Oceanic microseisms are small oscillations of the ground, in the frequency range of 0.05–0.3 Hz, associated with the occurrence of energetic ocean waves of half the corresponding frequency. In 1950, Longuet-Higgins suggested in a landmark theoretical paper that (i) microseisms originate from surface pressure oscillations caused by the interaction between oppositely travelling components with the same frequency in the ocean wave spectrum, (ii) these pressure oscillations generate seismic Stoneley waves on the ocean bottom, and (iii) when the ocean depth is comparable with the acoustic wavelength in water, compressibility must be considered. The efficiency of microseism generation thus depends on both the wave frequency and the depth of water. While the theory provided an estimate of the magnitude of the corresponding microseisms in a compressible ocean, its predictions of microseism amplitude heretofore have never been tested quantitatively. In this paper, we show a strong agreement between observed microseism and calculated amplitudes obtained by applying Longuet-Higgins’ theory to hindcast ocean wave spectra from the North Atlantic Ocean.

However, little work has been devoted to predict shorter period seismic waves recorded Received in revised form 5 June 2015 in coastal regions. Here we present an analytical framework that relates the signature of seismic noise Accepted 6 June 2015 recorded at 0.6–2 s periods (0.5–1.5 Hz frequencies) in coastal regions with deep-ocean wave properties. Available online 7 July 2015 Constraints on key model parameters such as seismic attenuation and ocean wave directionality are Editor: P. Shearer provided by jointly analyzing ocean-floor acoustic noise and seismic noise measurements. We show that Keywords: 0.6–2 s seismic noise can be consistently predicted over the entire year. The seismic noise recorded in this ocean waves period range is mostly caused by local wind-waves, i.e. by wind-waves occurring within about 2000 km of seismic noise the seismic station.

  • Noise Generation in the Solid Earth, Oceans, and Atmosphere, from Non
    Under consideration for publication in J. Fluid Mech. 1 Noise generation in the solid Earth, oceans, and atmosphere, from non-linear interacting surface gravity waves in finite depth FABRICE ARDHUIN1 A N D T. H. C. HERBERS2 1Ifremer, Laboratoire d’Oc´eanographie Spatiale, Plouzan´e, France 2Department of Oceanography, Naval Postgraduate School, Monterey, California 93943, USA (Received 22 June 2012; revised 22 September 2012; accepted ? ) Oceanic pressure measurements, even in very deep water, and atmospheric pressure or seismic records, from anywhere on Earth, contain noise with dominant periods between 3 and 10 seconds, that is believed to be excited by ocean surface gravity waves. Most of this noise is explained by a nonlinear wave-wave interaction mechanism, and takes the form of surface gravity waves, acoustic or seismic waves. Previous theoretical works on seismic noise focused on surface (Rayleigh) waves, and did not consider finite depth effects on the generating wave kinematics. These finite depth effects are introduced here, which requires the consideration of the direct wave-induced pressure at the ocean bottom, a contribution previously overlooked in the context of seismic noise. That contribution can lead to a considerable reduction of the seismic noise source, which is particularly relevant for noise periods larger than 10 s. The theory is applied to acoustic waves in the atmosphere, extending previous theories that were limited to vertical propagation only. Finally, the noise generation theory is also extended beyond the domain of Rayleigh waves, giving the first quantitative expression for sources of seismic body waves. In the limit of slow phase speeds in the ocean wave forcing, the known and well-verified gravity wave result is obtained, which was previously derived for an incompressible ocean.

  • Wind Wave - Wikipedia 1 of 16
    Wind wave - Wikipedia 1 of 16 Wind wave In fluid dynamics, wind waves, or wind-generated waves, are water surface waves that occur on the free surface of bodies of water. They result from the wind blowing over an area of fluid surface. Waves in the oceans can travel thousands of miles before reaching land. Wind waves on Earth range in size from small ripples, to waves over 100 ft (30 m) high.[1] When directly generated and affected by local waters, a Large wave wind wave system is called a wind sea. After the wind ceases to blow, wind waves are called swells. More generally, a swell consists of wind-generated waves that are not significantly affected by the local wind at that time. They have been generated elsewhere or some time ago.[2] Wind waves in the ocean are called ocean surface waves. Wind waves have a certain amount of randomness: Video of large waves from Hurricane Marie along the coast of Newport subsequent waves differ in height, duration, and shape Beach, California with limited predictability. They can be described as a stochastic process, in combination with the physics governing their generation, growth, propagation, and decay—as well as governing the interdependence between flow quantities such as: the water surface movements, flow velocities and water pressure. The key statistics of wind waves (both seas and swells) in evolving sea states can be predicted with wind wave models. Although waves are usually considered in the water seas Ocean waves of Earth, the hydrocarbon seas of Titan may also have wind-driven waves.[3] Contents Formation Types https://en.wikipedia.org/wiki/Wind_wave Wind wave - Wikipedia 2 of 16 Spectrum Shoaling and refraction Breaking Physics of waves Models Seismic signals See also References Scientific Other External links Formation The great majority of large breakers seen at a beach result from distant winds.

  • The Near-Coastal Microseism Spectrum: Spatial and Temporal Wave Climate Relationships Peter D
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 107, NO. B8, 10.1029/2001JB000265, 2002 The near-coastal microseism spectrum: Spatial and temporal wave climate relationships Peter D. Bromirski Integrative Oceanography Division, Scripps Institution of Oceanography, University of California, San Diego, La Jolla, California, USA Fred K. Duennebier Department of Geology and Geophysics, University of Hawaii at Manoa, Honolulu, Hawaii, USA Received 17 August 2000; revised 16 February 2001; accepted 20 August 2001; published 22 August 2002. [1] Comparison of the ambient noise data recorded at near-coastal ocean bottom and inland seismic stations at the Oregon coast with both offshore and nearshore buoy data shows that the near-coastal microseism spectrum results primarily from nearshore gravity wave activity. Low double-frequency (DF), microseism energy is observed at near-coastal locations when seas nearby are calm, even when very energetic seas are present at buoys 500 km offshore. At wave periods >8 s, shore reflection is the dominant source of opposing wave components for near-coastal DF microseism generation, with the variation of DF microseism levels poorly correlated with local wind speed. Near-coastal ocean bottom DF levels are consistently 20 dB higher than nearby DF levels on land, suggesting that Rayleigh/Stoneley waves with much of the mode energy propagating in the water column dominate the near-coastal ocean bottom microseism spectrum. Monitoring the southward propagation of swell from an extreme storm concentrated at the Oregon coast shows that near-coastal DF microseism levels are dominated by wave activity at the shoreline closest to the seismic station. Microseism attenuation estimates between on-land near-coastal stations and seismic stations 150 km inland indicate a zone of higher attenuation along the California coast between San Francisco and the Oregon border.

  • How Deep Ocean-Land Coupling Controls the Generation of Secondary Microseism Love Waves ✉ Florian Le Pape 1,2 , David Craig1,2 & Christopher J
    ARTICLE https://doi.org/10.1038/s41467-021-22591-5 OPEN How deep ocean-land coupling controls the generation of secondary microseism Love waves ✉ Florian Le Pape 1,2 , David Craig1,2 & Christopher J. Bean 1,2 Wind driven ocean wave-wave interactions produce continuous Earth vibrations at the seafloor called secondary microseisms. While the origin of associated Rayleigh waves is well understood, there is currently no quantified explanation for the existence of Love waves in the – 1234567890():,; most energetic region of the microseism spectrum (3 10 s). Here, using terrestrial seismic arrays and 3D synthetic acoustic-elastic simulations combined with ocean wave hindcast data, we demonstrate that, observed from land, our general understanding of Rayleigh and Love wave microseism sources is significantly impacted by 3D propagation path effects. We show that while Rayleigh to Love wave conversions occur along the microseism path, Love waves predominantly originate from steep subsurface geological interfaces and bathymetry, directly below the ocean source that couples to the solid Earth. We conclude that, in contrast to Rayleigh waves, microseism Love waves observed on land do not directly relate to the ocean wave climate but are significantly modulated by continental margin morphologies, with a first order effect from sedimentary basins. Hence, they yield rich spatio-temporal infor- mation about ocean-land coupling in deep water. 1 Geophysics Section, Dublin Institute for Advanced Studies, Dublin 2, Ireland. 2 iCRAG centre, University College Dublin, Dublin 4, Ireland. ✉ email: fl[email protected] NATURE COMMUNICATIONS | (2021) 12:2332 | https://doi.org/10.1038/s41467-021-22591-5 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-021-22591-5 better understanding of ocean generated seismic noise were analyzed for the period of March 2016 to March 2017.

Distributed acoustic sensing (DAS), an emerging 1234567890():,; technology that converts optical fiber to seismic sensors, allows us to leverage pre-existing submarine telecommunication cables for seismic monitoring. Here we report observations of microseism, local surface gravity waves, and a teleseismic earthquake along a 4192-sensor ocean-bottom DAS array offshore Belgium. We observe in-situ how opposing groups of ocean surface gravity waves generate double-frequency seismic Scholte waves, as described by the Longuet-Higgins theory of microseism generation. We also extract P- and S-wave : phases from the 2018-08-19 Mw8 2 Fiji deep earthquake in the 0.01-1 Hz frequency band, though waveform fidelity is low at high frequencies.
