Multiproxy paleoenvironmental reconstruction in the Caribbean

My research focuses on reconstructing paleoenvironmental conditions in the Caribbean region from multiple proxy sources.  I am currently working with Dr. DeLong to produce coral based reconstructions of Caribbean sea surface temperatures, for comparison and complimentary use with previous reconstructions of paleoclimatic and paleoceanic conditions in the region. As a masters student at Western Kentucky University I used the oxygen isotope values recorded in calcite stalagmite samples from Barbados to reconstruct precipitation variability over the past 1,500 years. As an undergraduate at the Pennsylvania State University I studied glacial hydrology and climatology. I enjoy exploring caves and interesting places around the Caribbean, as well as exploring the fine chemical and mineralogical structure of samples in the lab.


Jacob Warner, Ph.D Student


Raised in Baton Rouge, LA, I obtained my B.A. in Anthropology from LSU in the fall of 2010. I attended Dr. Chicoine’s field school at Caylán the summer of that same year, which sparked my interest in obtaining a graduate degree in archaeology. Once accepted into the M.A. program in Anthropology at LSU, I began to research trash flow as a proxy for human behavioral patterns at Caylán. Specifically, I am studying how artifact density can be used to infer patterns of object movement, and thus human activity, in the archaeological record. I am particularly interested in how the incipient urban environment of Caylán shaped the flow of objects through space. My work also includes a GIS component comparing the densities of various artifact types across the site through the use of interpolation mapping. I plan on completing this research and graduating in the Fall of 2014. Through collaborative work with Dr. Kristine DeLong, I have also begun research into paleoclimate and climate change along the Peruvian coast, specifically through examining the chemical composition of mollusk shells as a proxy for climate data. I plan to continue my education at LSU and obtain a Ph.D. expanding upon my mollusk research.

My view of life quoted from Mavis Leyrer, Octogenarian, of Seattle

Life is NOT a journey to the grave with the intention of arriving safely in one pretty and well-preserved piece, but to skid across the line broadside, thoroughly used up, worn out, covered in sweat and dirt and blood, screaming “holy sh*t, what a ride!”


Sweet after bitter, it’s been a long journey since 2005. I arrived at the Louisiana State University for my Ph.D under the supervision of professor Dr.DeLong. As an undergraduate and master’s student at the KongJu National University (KNU) (Korea), I studied quaternary environment, land & coastal geomorphology, climatology, and geography education. As a research assistant, I worked on soil, and gravels analysis, carbon dating, and pollen analysis in the six different research areas including coastal, marsh, quaternary & Holocene-environment fields. I obtained a second masters degree at the University of Louisiana Monroe where I studied geospatial analysis, FAA COA flight site for the Unmanned Aerial System (UAS) Program and Mapping with GIS, and Ground Penetrating Radar (GPR) & its processing software called GPR-SLICE in Poverty Point and Black Bayou Lake National Wildlife Refuge. Currently as a Ph.D student I am studying bioclimatology, tree ring, sediment core, microfossils, palynology, Isotope analysis, and coastal-environment & geomorphology in the Gulf of Mexico. My dissertation research is focused on a 50,000 year old (or older) Bald Cypress forest found under ocean sediment, as well as comparing records from the site to other paleoclimate records, including ice cores, corals, marine & lake sediments, using statistical & time series analysis.

Assessing the Environmental Conditions Affecting Gulf of Mexico Maritime Forests I am a native of Baton Rouge, Louisiana and enjoy working with anything coastal here along the Gulf of Mexico coastline. I have a B.S. and a M.S. in Geography here at Louisiana State University. My master’s research identified the occurrence of hurricanes using the dendrochronology of pine trees in Grand Bay National Estuarine Research Reserve, Mississippi. Dendrochronology is the study of tree rings. Trees lay one growth band each year and these growth bands can be affected by a multitude of environmental factors, including precipitation, temperature, disease, etc. Analyzing these tree rings can tell us about the history of environment near this tree. Hurricanes are one of these environmental factors, which cause stress to trees in the form of defoliation from strong winds, and lack of fresh water availability from storm surge. Coastal trees must repair the damage done by hurricanes and thus grow less in the tree trunk the following year. For my Ph.D., I hope to analyze the combine effects of hurricanes, sea-level rise, and prescribed fires on the ability for these coastal species to adapt to climate change.

Geaux Tigers!
