The Scientific Legacy of the CARIACO Ocean Time-Series Program.

The CARIACO (Carbon Retention in a Colored Ocean) Ocean Time-Series Program station, located at 10.50°N, 64.66°W, observed biogeochemical and ecological processes in the Cariaco Basin of the southwestern Caribbean Sea from November 1995 to January 2017.

Synchronous deglacial thermocline and deep-water ventilation in the eastern equatorial Pacific.

The deep ocean is most likely the primary source of the radiocarbon-depleted CO released to the atmosphere during the last deglaciation. While there are well-documented millennial scale ΔC changes during the most recent deglaciation, most marine records lack the resolution needed to identify more rapid ventilation events. Furthermore, potential age model problems with marine ΔC records may obscure our understanding of the phase relationship between inter-ocean ventilation changes.

Ecosystem responses in the southern Caribbean Sea to global climate change.

Over the last few decades, rising greenhouse gas emissions have promoted poleward expansion of the large-scale atmospheric Hadley circulation that dominates the Tropics, thereby affecting behavior of the Intertropical Convergence Zone (ITCZ) and North Atlantic Oscillation (NAO). Expression of these changes in tropical marine ecosystems is poorly understood because of sparse observational datasets. We link contemporary ecological changes in the southern Caribbean Sea to global climate change indices.
