Introduction
| This project will provide a history of climate and environmental changes that can be used to estimate impacts of potential future climate warming and provide a baseline for identifying any human related future changes. |
|
This project documents paleoceanographic, climatic and environmental changes in the Gulf of Mexico (GOM) and adjacent land areas. The information is used to determine cycles of natural climate variability and environmental change primarily over the last 10,000 years. The project is also developing records of drought/flood cycles for the central and southwest United States, paleo-hypoxia records for the Texas and Louisiana shelf, and records of summer monsoon intensity.
Information on natural climatic variability is needed to establish possible causes of climate variation on human timescales and help discriminate between natural variability and any human-related changes. Improved records of any past changes in oxygen content of bottom waters on the continental shelf of Louisiana and Texas are directly relevant to understanding the role of natural variability versus human activities in the periodic development of hypoxic conditions in the Gulf of Mexico. Ultimately better understanding of the frequency and magnitude of natural climate variability of the Holocene will lead to better forecasts of future change and its societal impact.
