Some considerations on coastal processes relevant to sea level rise
The effects of potential sea level rise on the shoreline and shore environment
have been briefly examined by considering the interactions between sea level rise and
relevant coastal processes. These interactions have been reviewed beginning with a
discussion of the need to reanalyze previous estimates of eustatic sea level rise and
compaction effects in water level measurement. This is followed by considerations on
sea level effects on coastal and estuarine tidal ranges, storm surge and water level
response, and interaction with natural and constructed shoreline features. The
desirability to reevaluate the well known Bruun Rule for estimating shoreline recession
has been noted. The mechanics of ground and surface water intrusion with reference to
sea level rise are then reviewed. This is followed by sedimentary processes in the
estuaries including wetland response. Finally comments are included on some probable
effects of sea level rise on coastal ecosystems.
These interactions are complex and lead to shoreline evolution (under a sea level
rise) which is highly site-specific. Models which determine shoreline change on the
basis of inundation of terrestrial topography without considering relevant coastal
processes are likely to lead to erroneous shoreline scenarios, particularly where the
shoreline is composed of erodible sedimentary material.
With some exceptions, present day knowledge of shoreline response to hydrodynamic
forcing is inadequate for long-term quantitative predictions. A series of interrelated
basic and applied research issues must be addressed in the coming decades to
determine shoreline response to sea level change with an acceptable degree of
confidence. (PDF contains 189 pages.
IDE spatio-temporal impact fluxes and high time-resolution studies of multi-impact events and long-lived debris clouds
The purpose of the Interplanetary Dust Experiment (IDE) on the Long Duration Exposure Facility (LDEF) was to sample the cosmic dust environment and to use the spatio-temporal aspect of the experiment to distinguish between the various components of the environment: zodiacal cloud, beta meteoroids, meteor streams, interstellar dust, and orbital debris. It was found that the introduction of precise time and even rudimentary directionality as co-lateral observables in sampling the particulate environment in near-Earth space produces an enormous qualitative improvement in the information content of the impact data. The orbital debris population is extremely clumpy, being dominated by persistent clouds in which the fluxes may rise orders of magnitude above the background. The IDE data suggest a strategy to minimize the damage to sensitive spacecraft components, using the observed characteristics of cloud encounters

The Early Royal Society and Visual Culture
Recent studies have fruitfully examined the intersection between early modern science and visual culture by elucidating the functions of images in shaping and disseminating scientific knowledge. Given its rich archival sources, it is possible to extend this line of research in the case of the Royal Society to an examination of attitudes towards images as artefacts –manufactured objects worth commissioning, collecting and studying. Drawing on existing scholarship and material from the Royal Society Archives, I discuss Fellows’ interests in prints, drawings, varnishes, colorants, images made out of unusual materials, and methods of identifying the painter from a painting. Knowledge of production processes of images was important to members of the Royal Society, not only as connoisseurs and collectors, but also as those interested in a Baconian mastery of material processes, including a “history of trades”. Their antiquarian interests led to discussion of painters’ styles, and they gradually developed a visual memorial to an institution through portraits and other visual records.AH/M001938/1 (AHRC
