Abstract
Greenhouse-gas emissions are rapidly transforming the Earth's system through complex feedback mechanisms affecting biogeochemical cycles. The rise in atmospheric CO2 causes global warming, leading to ocean stratification and modifying ocean circulation patterns and deep-water ventilation, while the CO2 absorbed by the oceans causes ocean acidification and promotes calcium carbonate dissol…

Abstract
The way the circulation and the chemistry of the oceans interact with the climate on a milenial scales, and how these interactions can be changed in response to increasing greenhouse gases, is gaining increasing attention from the scientific community. Through geochemical analyzes, carried out mainly in foraminifera preserved in marine sediments, it is possible to reconstruct the ocean ci…
Paleo-pH, the carbonate system and climate variation: using boron isotope and B/Ca variations in foraminifera as proxies, AP.R
Abstract
The study site KF-12, retrieved in the SW Atlantic (Brazilian Margin) is proposed to carry out the reconstruction of sea-surface and deep ocean conditions during the last climate cycle in a region with deep and bottom waters influenced both by north and south dynamics. The main objective is to obtain several climate parameters to have a continuous record that can be used to identify clima…
High resolution climate record for the last climatic cycle in the subtropical SW Atlantic, AP.R
Abstract
Understand the processes and mechanisms that control the climate, its dynamics over the last climatic cycles, as well as the response time to different systems and regions, and the connection that exists between them, are a goal and a priority for the current state of scientific knowledge. Faced with the worrying situation that outlines the results of the recent Intergovernmental Panel on…
