SynopsisDeterminations of dissolved oxygen and nutrients in the water overlying the sediments, of sedimentation rates, and of redox values, acidity, dissolved sulphide, carbon, nitrogen and cellulose values at different levels in the sediments themselves have been carried out in various parts of Sullom Voe. The effects of oxygen depletion following intermittent stagnation of the bottom water in the inner basin on carbon cycling in the sediments are discussed and contrasted with the chemistry of oxygen-rich sediments elsewhere in the voe.

Children between the ages of eight and twelve, known as teenagers or teens, have become a lucrative customer base. These teens are considered to be ‘in between’ the traditional child and teenager stages of development. South African society has undergone a sweeping change in its vital institution–the family. Trends such as smaller family size, single parent households, dual incomes and postponing children until later in life means that society is increasingly becoming cash rich and time poor. Guilt plays a major contributing role in spending decisions as time-stressed parents substitute material goods for quality time spent with teens, therefore opening a floodgate to marketers who monopolize on this pang and guilt factor. Guilt consumerism has now transformed teens into key players in marketing strategies. This research paper aims to provide an insight into the rising consumerism in teens due to the ‘nag’ and ‘pester’ power- bug that has fuelled marketing tactics.
