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. Representation
of these waves is a challenge, requiring high-resolution resolution numerical models. Likewise, the heterogenous character
of the waves presents many difficulties for measurement and monitoring.

These challenges are key motivations for this NOPP study.
