The resurgence of Cabo Frio (RJ) during the mid-Holocene

The upwelling is characterized by the rise of waters with lower temperatures, previously located at greater depths in the water column. Through air-sea interaction, this process modifies air temperature and local wind circulation, affecting the region's weather and climate. It contributes to an increase in nutrients in the water column, supporting regional fishing productivity. These regions have a high sedimentation rate and are important for understanding climate variations, as they indicate processes related to environmental changes. This study investigates the influence of atmospheric and oceanic dynamics on the upwelling process in the Cabo Frio region (RJ), using results from paleoclimate simulations. The mid-Holocene period was analyzed, when there was variation in the seasonal and latitudinal distribution of incident solar radiation, and the pre-industrial period (control).
