- Abstract:
- Internal wave with a soliton-like, large amplitudes within several kilometers, is frequently observed in the sea surface caused by tidal rectification due to sill or rough topographic changes. Internal waves can perturb current and density field, initiate bottom sediment re-suspension and mix nutrients to photic zone. Previous studies indicate that the appearance of internal wave in the Lombok Strait have been detected in SAR image data. This paper studies effect of internal wave in the Lombok Strait on distribution of chlorophyll in the surrounded areas using SeaWiFS and ERS SAR images data during 1996-2001 period. The preliminary result concludes that the internal waves presumably affect chlorophyll distribution spreading southeastward in the coast off Bali Island.
