Sea surface manifestations of several internal wave packets south and north of the sill between the Nusa Penida and Lombok islands. It is very probable that the wave packets were generated during the same tidal cycle. At least four internal wave packets are clearly visible south of the sill: one southward-propagating packet consisting of 8 solitons, one southwestward propagating packet, and two packets south of the sill propagating in opposite directions. The dark triangle-shape area is very likely an island wake downstream from Nusa Penida island. A wave packet propagating into the Bali Sea has a very weak radar contrast.
