provides an analysis of the environmental factors controlling the positions of the coastal zone and, in particular, the nature of the interaction between changes in coastal position and water-level, or relative sea-level movement. Conclusions are drawn about the contribution of archaeology to sea-level-coastal data and of the subject's potential in helping understanding of the broader controls upon coastline development

evidence for the use of water transport in the southern North Sea and Channel region during the period c. 300 BC to c. AD 50 is evaluated and boat types, building methods, means of propulsion, and likely performance are described. An attempt is made to identify the characteristics of the Celtic tradition of planked boat and shipbuilding. Methods of navigation, trade routes, harbours and landing places are also discussed

description and discussion of the ship, including its building sequence and possible evidence from coins. It is suggested that it was of a similar type to that used by the Veneti of north-west Gaul, and may have been built on the Rhine or the Thames, but that it is unlikely that coins of Cunobelin depict ships of this type

examines written sources and other evidence from the sixth to tenth centuries in an attempt to answer the question of whether the name and adjective `Frisian' really referred to Frisians, and if not, to what these terms actually referred; includes

suggests that careful reading of the textual evidence suggests that it was the Franks who were regarded as the chief threat to the Channel in the late-third and early-fourth centuries, the threat being to the German and Gallic coasts, and that it was only towards the end of the fourth century that Saxon raids on the north side of the Channel were recorded. This implies that the Saxon Shore was only so named around the year 400, and provides a context for later Frankish interest in England

discusses the role of the North Sea as a crucial zone of interaction in early medieval state formation, in relation to the Kingdom of East Anglia, and considers such questions as whether the sea was crossed, if so how, and what this signified for the peoples around the edge of the sea
