An International Consortium for the Study of Global and Climate Changes in the Western South Atlantic

The South American Climate Change (SACC) Consortium is an initiative sponsored by the IAI through the Cooperative Research Networks (CRN) Program.

The GENERAL PURPOSE of the SACC Consortium is:
To coordinate and enhance human and institutional resources in South American countries, in order to advance the understanding of the coupled effects of global change and climate variability on the oceanic, atmospheric and terrestrial ecosystems of the Western South Atlantic region.

The primary SCIENTIFIC GOAL of SACC is:
To understand the interactive relationship of the southwestern South Atlantic sea surface temperature (SST) and the larger scale climate behavior.

• Describe the spatial and temporal scales of SST anomalies in the southwestern South Atlantic (SWA) and understand their coupling to ocean stratification and atmospheric forcing.
• Advance our understanding of climate variability as a result of changes in the thermohaline circulation and water mass properties of the southwestern South Atlantic.
• Determine the behavior of the Brazil/Malvinas Confluence and associated climate variations in response to local and remote forcing, both oceanic and atmospheric.
Determine the relationship between oceanic variability and ecosystem changes in shelf and terrestrial environments in response to regional hydrology, including rainfall over South America and river runoff.
