K1 High amplitude internal waves Strait of Gibraltar Algeciras bay Sentinel-2 HICO
AB High Amplitude Internal Waves (HAIWs) are physical processes observed in the Strait of Gibraltar (thenarrow channel between the Atlantic Ocean and the Mediterranean Sea). These internal waves aregenerated over the Camarinal Sill (western side of the strait) during the tidal outflow (toward theAtlantic Ocean) when critical hydraulic conditions are established. HAIWs remain over the sill for up to4 h until the outflow slackens, being then released (mostly) towards the Mediterranean Sea. These havebeen previously observed using Synthetic Aperture Radar (SAR), which captures variations in surfacewater roughness. However, in this work we use high resolution optical remote sensing, with the aim ofexamining the influence of HAIWs on biogeochemical processes. We used hyperspectral images from theHyperspectral Imager for the Coastal Ocean (HICO) and high spatial resolution (10m) images from theMultiSpectral Instrument (MSI) onboard the Sentinel-2A satellite. This work represents the first attemptto examine the relation between internal wave generation and the water constituents of the CamarinalSill using hyperspectral and high spatial resolution remote sensing images. This enhanced spatial andspectral resolution revealed the detailed biogeochemical patterns associated with the internal waves andsuggests local enhancements of productivity associated with internal waves trains.
