Long term ocean observations can help us detangle the intricate web of internal wave across the globe Global ocean maps illustrate the low-mode internal wave field at the M2 tidal frequency (color-scale image) in relation to historical ocean repeat data collections: the WOCE/GO-SHIP transects (top center), the Scripps high-density XBT archive (bottom left), and the AOML high-density XBT archive (bottom right). The tidal internal waves, which are hypothesized to be a significant source of energy for the broadband internal wave field, are heterogenously distributed throughout the ocean basins.
