NOAA/WDS Paleoclimatology - Common Era Evolution of Ocean Temperature
This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Paleoclimatology Modeling. The data include parameters of paleoclimatic modeling with a geographic location of Global Ocean. The time period coverage is from 1935 to -65 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.

Supplemental Information | STUDY NOTES: This data package includes an inversion of ocean data to reconstruct the evolution of Common Era (15-2015 CE) ocean temperature (labeled OPT-0015). It also includes the output of a model simulation initialized from equilibrium in the year 15 (EQ-0015) and 1750 (EQ-1750). Output includes both the potential temperature and potential temperature anomaly fields ABSTRACT SUPPLIED BY ORIGINATOR: Proxy records show that before the onset of modern anthropogenic warming, globally coherent cooling occurred from the Medieval Warm Period to the Little Ice Age. The long memory of the ocean suggests that these historical surface anomalies are associated with ongoing deep-ocean temperature adjustments. Combining an ocean model with modern and paleoceanographic data leads to a prediction that the deep Pacific is still adjusting to the cooling going into the Little Ice Age, whereas temperature trends in the surface ocean and deep Atlantic reflect modern warming. This prediction is corroborated by temperature changes identified between the HMS Challenger expedition of the 1870s and modern hydrography. The implied heat loss in the deep ocean since 1750 CE offsets one-fourth of the global heat gain in the upper ocean. |
Purpose | Computer simulations of past climate. Variables provided as model output are described by parameter keyword. In some cases the parameter keywords are a subset of all archived model output, and additional output is available upon request. Additional summary information can be found in the abstracts of papers listed in the dataset citations. |
