The Holocene sedimentary facies of the Fenland are described using a lithological database and new cores recovered as part of the Land–Ocean Interaction Study. Landward, the Holocene sequence is dominated by mud facies with intercalated peat layers, whereas the seaward areas are sand-dominated. The sedimentological characteristics of the mud facies are homogeneous and are similar for the whole sequence. Glacial deposits located north of The Wash are thought to be the main sediment sources. The sand facies generally fines upwards and the chemistry reflects this change. However, elemental ratios show only slight variations between the two facies implying a general constancy of sediment provenance. The evolution of the Fenland has been dominated by three main events. Firstly, the initial post-glacial transgression, which started c. 7850 cal. BP. Secondly, the sedimentary infilling of the embayment with rising sea-level; deposition of intertidal clastic sediments alternating with peat accumulation. Thirdly, renewed expansion of tidal flat areas between c. 2750 and 1500 cal. BP forming the final clastic fill.

Holocene Land–Ocean Interaction and Environmental Change around the North Sea
The majority of the research presented in this volume arises from the Land—Ocean Evolution Perspective Study (LOEPS), which was one component of the Land—Ocean Interaction Study (LOIS - funded by the Natural Environment Research Council).
The main aim of LOEPS was to describe the evolution of coastal system from the Holocene to the Present, in response to changes in relative sea level and the impact of human activities.
A key element in the success of LOEPS has been the integration and interaction between the various element of the research programme. The papers published here reflect this integration rather than summarizing the results of individual research projects or the achievements of a single LOEPS objective.
The contributions fall into four sections: techniques; Humber catchment; other areas within the studied region; regional-scale analysis.
