...A. H. El-Shaarawi; M. Munawar The article uses exploratory and change-point methods to investigate changes in the level and spatial pattern of size-fractionated primary productivity in Lake Erie during the summers of 1992 and 1996. In July 1992 and 1996 primary productivity measurements were made...

...Xiaomei Liao; Jinfeng Ma; Haigang Zhan More than ten years of satellite-derived net primary production (NPP) data were used to investigate the interannual variations of NPP associated with two different types of El Niño in the South China Sea (SCS). Results of the empirical orthogonal function...
