Description
Mixing in the ocean: laboratory demonstrations simulate processes occurring within the ocean. -- El Nino 1982/83: sequence compiled from long term infrared measurements of surface ocean temperatur...es collected by polar orbiting satellites to create a continuous synoptic view of sea surface temperatures, the El Nino event is particularly evident. -- Salt rejection: laboratory demonstration showing how droplets of very saline water sink beneath ice forming at the sea surface. -- Plankton: demonstration of the use of a trawled plankton net and an attempt to distinguish plants, animals and larval stages under a microscope. -- Rocky shores and Benthic communities: A time lapse sequence showing large and small tidal excursions & a look at the rich benthic community of animals that graze on seaweeds or detritus on the seabed. -- Waves: laboratory teank demonstration of the basic characteristics of waves in fluids & an electronic display to demonstarte the formation of a wave group. -- Waves across the Pacific: the story of the classic investigation of dispersion across an ocean. -- Estuaries: a discussion into how physical processes such as ocean tides influence the movement of river water and sediments & an investigation into some of the burrowing organisms that live in sand banks of the Tay estuary.
