Pacific Ocean Climate Variability: Marine Records of North American Precipitation Patterns
Together with a companion project that focuses on terrestrial proxy records, this project aims to reconstruct patterns of climate variability along the Pacific coasts of North America during the last 15,000 years through analysis of diatoms, foraminifers, silicoflagellates, pollen, charcoal, geochemistry, isotopes, and other proxies from marine, estuarine, and lacustrine sediment cores. We produce high-resolution records of marine sea-surface temperature and surface water productivity from the Pacific margins between southeastern Alaska and Mexico and compare these with terrestrial records from estuaries and lakes primarily in California and Nevada. These decadal scale records of the past 1,200 years can be used in regional and global reconstructions of the Medieval Climate Anomaly (~AD 950-1250), and the Little Ice Age (~AD 1350-1850). We also aim to assess (on a regional basis) the links between extensive drought and offshore sea surface temperatures. Our efforts will aid resource managers in their efforts to understand the variability of surface processes in the West and to mitigate the effects of climate change on ecosystems.
Why is this research important?
Modern climate of the Pacific coasts of North America and much of the western US is largely dictated by the sea surface temperatures and atmospheric conditions in the eastern North Pacific (i.e., El Niño/La Niña, Pacific Decadal Oscillation). Understanding patterns of natural climate variability is critical to the analysis and interpretation of the impacts of anthropogenic changes. One impact has been in the West; where water availability is the issue of the greatest concern both presently and in projected future (global warming) climate scenarios.

Holocene Climate of the Pacific Coasts
This project uses marine, estuarine, and lacustrine sediment cores along the Pacific coast of the US to reconstruct climate variability during the last 15,000 years, with a special emphasis placed on high resolution studies of the past 2,000 years. We aim to determine the natural variability of climate (such as sea surface temperatures) in marine records off the western US on annual to millennial time scales during the past 15,000 years, extracting cycles such as the Pacific Decadal Oscillation (PDO). Diatoms, foraminifers, silicoflagellates, pollen, geochemistry and other proxies are used and compared with proxy precipitation records in the western US. Records of climate variability in North Pacific estuaries and lakes during the past 15,000 years will also be developed to determine ecosystem changes and to assess regional trends. These records will be compared with published climate records in the West in order to assess (on a regional basis) the links between extensive drought and offshore sea surface temperatures. These records will also be used to understand the variability of surface processes in the West.
Why is this research important?
Modern climate of the Pacific coastal states and much of the western US is largely dictated by the sea surface temperatures and atmospheric conditions in the eastern North Pacific (El Nino/La Nina, PDO). Distinguishing natural climate variability from anthropogenic change is critical. In the West, water availability is the issue of greatest concern both presently and in projected future (global warming) climate scenarios.
