Figure 1. View of the Gulf Stream during summer off the southeastern United States. Darkest red colors (black line follows main current axis) are the warmest waters. The deep coral habitats sampled during our cruises are all underneath the Gulf Stream. It is a powerful force in the area, influencing marine ecology and weather patterns of the region. Our analysis of the history contained in the corals may help understand how this current has interacted with the area. Image courtesy of Ross et al, NOAA, HBOI.
