The sea-level record preserved in ancient shorelines forms a basis for studies of tectonic uplift, glacial loading, and the changing volume of the oceans. The existing record is derived largely from depositional features such as beach ridges and coral reefs, which contain material suitable for radiometric dating. Erosional shorelines have proved more difficult to date. Direct age estimates for shore platforms can now be obtained with exposure-dating techniques based on cosmic-ray-produced isotopes. Here we report measurements of cosmogenic 36 Cl on the Main Rock Platform in western Scotland that indicate its formation in a postglacial event spanning less than a few thousand years. Together with isostatic modeling, the 36 Cl results suggest cutting during the Younger Dryas (in Britain, the "Lateglacial" or "Loch Lomond") Stadial, when stable sea level and severe climatic conditions combined to enhance bedrock erosion.

Chapter 3 OJI conditioning and dewatering is very qualitative. A brief discussion on the chemical conditioning process (mainly via polymer addition) is presented, but information on how to evaluate optimal polymer choice of polymer dosage is lacking. A list of different dewatering technologies is presented but without suficient design information, except for a range in expected effluent suspended solids concentrations. Case studies are included, but again lack detail.Chapter 4 on digestion presents a good comparison between traditional aerobic, anaerobic, and autothermal thermophilic digestion (ATAD) processes. ATAD is the only process that can be used as a technology to further reduce pathogens (PFRP). Adequate process design information on any of the processes is absent, neither are quantitative criteria presented for the evaluation of system performance. An illustrative comparison on the design and capital cost of the 3 different digester processes is presented, but is hampered by the absence of a defined design goal.Chapter 5 on composting is again very
