Life in the oceanic realms

The marine environment includes the nutrient-rich coastal waters, relatively nutrient-poor open oceanic waters, coral reef atolls, metal-rich hydrothermal vent fluids with temperatures of 200–350°C, cold-seeps, estuaries, mangrove swamps, intertidal beaches and rocky shores. Oceans are home to some of themost diverse and unique life forms. This article is an attempt to introduce some of the fundamentals of biologicaloceanography andmarine biologyto describe life in the sea.     

A Study of the Educational Provision for Head-injured Children

Anne Jones (of the Froebel Institute College, Roehampton Institute of Higher Education) and David Johnson (Head of the Department of Neuropsychology, Astley Ainslie Hospital, Edinburgh) consider some of the problems experienced by children with head-injury on their return to school. Although education is an integral part of rehabilitation, the organisation of services and the provision of accurate information, training and communication between different agencies were all found to be inadequate. Given the high incidence of head-injury, urgent attention to these problems is essential.
