Development of a rare earth element paleoproxy

Creator:

Haley, Brian Alexander, 1973-

Abstract:

This thesis describes the development of a rare earth element (REE) proxy for paleoceanographic studies of climate change. This work was done in three stages with the goal: (1) To develop a cleaning method that overcomes the problems of REE readsorption; (2) To measure pore water REEs for evaluation of...

Late Quaternary paleoceanography of the Northeast Pacific and Atlantic Oceans based on diatom transfer functions

Creator:

Lopes, Cristina Isabel Coelho Dias

Abstract:

Modern upwelling conditions and corresponding oceanographic properties are investigated and reconstructed for the Late Quaternary. The oceanographic conditions considered influence diatom ecology and the record of fossil diatom frustules in the sediments. Diatoms from modern sediments are evaluated as paleoceanographic proxies and transfer functions (TFs) are calibrated using the Imbrie...
