Nutrient utilisation and weathering inputs in the Peruvian upwelling region since the Little Ice Age
For this study two sediment cores from the Peruvian shelf covering the time period between the Little Ice Age (LIA) and present were examined for changes in productivity (biogenic opal concentrations (bSi)), nutrient utilisation (stable isotope compositions of silicon (δSiopal) and nitrogen (δNsed)), as well as in ocean circulation and material transport (authigenic and detrital radiogenic neod...

15 صفحه اولEvidence for external forcing of the Atlantic Multidecadal Oscillation since termination of the Little Ice Age
The Atlantic Multidecadal Oscillation (AMO) represents a significant driver of Northern Hemisphere climate, but the forcing mechanisms pacing the AMO remain poorly understood. Here we use the available proxy records to investigate the influence of solar and volcanic forcing on the AMO over the last ~450 years. The evidence suggests that external forcing played a dominant role in pacing the AMO ...
متن کاملManaging the Peruvian Upwelling Ecosystem:
A brief review is given of Ibe interrelationships and implications of Ibe findings reported in Ibe contributions included in this volume. Emphasis is given to some questions Ibat now appear crucial, e.g. Ibe cannibalization of anchoveu eggs and biannual cycles in anchoveta recruitment and their possible cause(s). Some suggestions are made for future research on various elements of Ibe Peruvian ...
