Future observational and modelling needs indentified on the basis of the existing shelf data
print NOWESP has compiled a vast quantity of existing data from the north-west European shelf. Such a focused task is without precedence. It is now highly recommended that one, or a few national and international data centres or agencies should be chosen and properly supported by the E.U., where all...
