Abstract. Seismic oceanography is a new cross-discipline between geophysics and oceanography that uses seismic reflection data to image and study the oceanic water column. Previous work on seismic oceanography was largely limited to two-dimensional (2D) seismic data and methods. Here we explore and quantify temporal and spatial variations in three-dimensional (3D) seismic oceanography to address whether 3D seismic imaging is meaningful in all directions and how one can take advantage of the variations. From a 3D multichannel seismic survey acquired for oil and gas exploration in the Gulf of Mexico over a 6-month period, a 3D oceanic seismic volume was derived. The 3D seismic images exhibit both temporal and spatial variations of the ocean, and theoretical and data analyses were used to quantify their contribution. Our results suggest that temporal variation is more prominent in the crossline direction than in the inline direction, causing discontinuities in crossline images. However, a series of 3D inline images can be seen as snapshots of the water column at different times, capturing temporal variation of thermohaline structures induced by ocean dynamics. Our findings suggest the potential uses of marine 3D seismic data in studying time-evolving mesoscale ocean dynamics.

Abstract. Seismic oceanography is a new cross-discipline between geophysics and oceanography that uses seismic reflection data to image and study the ocean water column. Previous works on seismic oceanography were largely limited to two-dimensional seismic data and methods. We present a complete three-dimensional (3D) oceanic seismic study and explore its imaging capability in seismic oceanography. From a 3D multichannel seismic survey acquired for oil and gas exploration in the Gulf of Mexico over six months period, a 3D water-column seismic volume was derived. The 3D seismic volume exhibits both temporal and spatial variations of the ocean, and theoretical and empirical analyses were performed to discriminate their contribution. Our analyses shows that temporal variation is largely embedded along crossline direction, hence deteriorating the quality of seismic images; however, inline sections, which can be seen as snapshot representation of the water column, allow to capture not only thermohaline structure but also the temporal evolution of the ocean dynamics. Our finding highlights that appropriately processed and analyzed 3D seismic data not only provide superior images of the ocean structure but also can be useful for investigation of temporal evolution of mesoscale ocean dynamics.
