1. PHOTOGRAPHIC RECORDS (sets to be made available to AAD multimedia centre for permanent record) 1a Glacier margin positions Aerial oblique and some ground-based photographs 1b Summit crater of Big Ben Aerial oblique photographs 1c Environmental impacts of research Ground-based photographs of research excavation sites (before excavation, during excavation, after rehabilitation, GPS locations) 2. TOPOGRAPHIC PROFILES 2a Intended long term coastal monitoring sites Simple profiles from permanent markers (with GPS) compiled from compas and clinometer traverses (amply detailed to capture changes at the scales being observed and simple to repeat) 2b Beach profiles Simple profiles compiled from clinometer and tape traverses to characterise selected beaches as part of geomorphological survey; GPS locations 2c. Dovers Moraine profiles Simple profiles compiled from clinometer, compass and tape traverses to characterise ridge sequence and establish approximate altitude of palaeolake shorelines; some GPS locations. Details are given in the spreadsheet at the url below. 3. GLACIAL LANDFORMS AND RELATIVE DATING 3a Reconnaissance-level landform survey Morphostratigraphic relationships between landforms recorded in note form, photographically, or directly onto field maps; by estimation with some GPS control. 3b Criteria for relative dating Semiquantitative data on moraine morphology; descriptive data on subsurface weathering status; GPS locations 3c Sampling Samples obtained for laboratory analysis (mechanical and chemical analysis and some radiometric dating - processing will be dependent upon obtaining adequate financial resources; GPS locations; samples, sampling sites and desired use as indicated in the spreadsheet at the url below. The downloadable dataset contains: 1. Photographic record of glacier margins and summit of Big Ben as at December 2000 2. Simple topographic profiles of eroding coastlines for long term monitoring processes, selected beach profiles and profiles over Dovers Moraine 3. Data on glacial geomorphology and glacial geology including postdepositional modification of moraines and glacial sediments and samples for weathering studies and possible radiometric dating. The fields in this dataset are: northing easting height (ASL) location sample number sample type sample date longitude latitude landform general profile weathering and sediment stratigraphy sampling photographs
