We carried out a detailed rock magnetic and paleomagnetic study of deep-sea sediments from selected intervals of Site 1233 in order to assess whether they contain reproducible evidence for submillennial-scale environmental, climatic, and geomagnetic field variability. Three 1.5-m sediment intervals from oxygen isotope Stages 1, 2, and 3 were sampled...
Paleomagnetic analysis and radiocarbon dating of an expanded Holocene deep-sea sediment sequence
recovered by Integrated Ocean Drilling Program (IODP) Expedition 303 from Labrador Sea Site U1305
(Lat.: 57°28.5 N, Long.: 48°31.8 W, water depth 3459 m) provides insights into mechanisms that drive
both paleomagnetic secular variation (PSV) and magnetization acquisition...

Intramolecular cyclization of organometallic compounds represents
a promising tool for synthesis in general. The use of strategically-
placed heteroatoms in the cyclizing molecule can influence
the stereochemistry and/or efficiency of an organometallic cyclization
while providing for functionality in the cyclic product.
The work described herein first concerns cyclizations of organolithiums....
An on-line trace enrichment (TE) system, based on high pressure
liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has
been developed for trace metal analysis. The sample is pumped through
a column filled with a cation exchange resin which traps metal ions.
The ions are subsequently stripped from the column...
Understanding how the latitudinal distribution of methane sources changed between stadial and interstadial climate states during the last glacial period can provide important clues about how terrestrial hydroclimate and ecosystems evolved between these different states. The punctuation of the millennial-scale structure by Heinrich events is also of interest in this...
This research presents a u-channel based study of the natural remanent magnetization (NRM), the laboratory magnetization, Anhysteretic Remanent Magnetization (ARM), and magnetic susceptibility (k), from the upper 100 m of International Ocean Discovery Program (IODP) Expedition 383 Site U1543 in the eastern South Pacific sector of the Southern Ocean. Alternating...
Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of...
