Our benthic foraminiferal stable isotope comparisons show that a large d13C offset developed between mid-depth (~600 meters) and deep (>1000 meters) western North Atlantic waters in the early Oligocene, indicating the development of intermediate-depth d13C and O2 minima closely linked in the modern ocean to northward incursion of Antarctic Intermediate Water. At the same time, the ocean's coldest waters became restricted to south of the ACC, probably forming a bottom-ocean layer, as in the modern ocean. We show that the modern four-layer ocean structure (surface, intermediate, deep, and bottom waters) developed during the early Oligocene as a consequence of the ACC. #------------------ # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: OCE 06-23256, OCE 09-28607, EAR03-07112, EAR05-06720 #------------------ # Site_Information # Site_Name: ODP1053 # Location: Ocean>Atlantic Ocean>North Atlantic Ocean # Country: # Northernmost_Latitude: 29.9923 # Southernmost_Latitude: 29.9923 # Easternmost_Longitude: -76.5236 # Westernmost_Longitude: -76.5236 # Elevation: m #------------------ # Data_Collection # Collection_Name: ODP1053-2011iso # Earliest_Year: 36622000 # Most_Recent_Year: 33947000 # Time_Unit: Cal.
