Structure and Development of the Greenland-Scotland Ridge
A group of geoscientists from a number of NATO countries met under NATO sponsorship in Copenhagen on February 27 and 28, 1978, and formulated a proposal entitled "EVOLUTION OF THE GREENLAND ICELAND-FAEROE-SCOTLAND RIDGE, A KEY AREA IN MARINE GEOSCIENCE". This part of the North Atlantic Ocean is of particular interest because of its anomalously shallow bathymetry which has profoundly influenced many aspects of the evolution of the North Atlantic. The proposed investigations therefore aim to study the deep crustal structure including relationship of continental and oceanic crust, history of subsidence of the ridge including its past role as a land bridge, age of the oceanic basement along it a...

Ocean Seismo-Acoustics
Seafloor investigation has long been a feature of not only seismology but also of acoustics. Indeed it was acoustics that produced depth sounders, giving us the first capability of producing both global and local maps of the seafloor. Subsequently, better instrumentation and techniques led to a clearer, more quantitative picture of the seabed itself, which stimulated new hypotheses such as seafloor spreading through the availability of more reliable data on sediment thickness over ocean basins and other bottom features. Geologists and geophysicists have used both acoustic and seismic methods to study the seabed by considering the propagation of signals arising from both natural seismic event...
The Role of Solar Ultraviolet Radiation in Marine Ecosystems
The inspiration for this monograph derived from the realization that human technical capacity has become so great that we can, even without malice, substantially modify and damage the gigantic and remote outer limit of our planet, the stratosphere. Above the atmosphere of our ordinary experience, the stratosphere is a tenuous layer of gas, blocked from rapid exchange with the troposphere, some twenty kilometers above the surface of the earth, seldom reached by humans, and yet a fragile shell which shields life on earth from a band of solar radiation of demonstrable injurious potential. It is immediately obvious that if stratospheric ozone were reduced and consequently the intensity of solar ...
Dynamic Processes in the Chemistry of the Upper Ocean
The. Advanced Research Inst i tute (ARI) on Dynamic Processes in the Chemistry of the Upper OCean had its origins in discussions by the NATO Special Programme Panel on Marine Sciences during 1978 when a wide range of topics for future ARIs was being considered. What was then envisaged was a workshop on chemical aspects of the oceanic mixed layer, at which consider ation would be given to the inputs, cycling and removal of material, and the problems involved in the quantitative assessment of fluxes. It was realised that any attempt to model chemical processes would need the active collaboration of workers from other fields, especially physical oceano graphers concerned with air-sea interactio...
