Stratigraphy-Earth History

Beginning in 1990 and continuing to the present the Sequence Stratigraphy group has been studying the rise and fall of sea level and its effects on sedimentation patterns on the Atlantic Margin. During this time we have drilled and analyzed coreholes on the New Jersey, Delaware, and Virginia coastal plains (ODP Legs 150X, and 174AX; ICDP-USGS Eyreville, Va corehole). We have also drilled coreholes on the modern middle continental shelf (IODP Expedition 313) and the modern outer continental shelf and slope (ODP Legs 150 and 174A). Our studies encompass unique views of major climate transitions in Earth history, specifically the Cretaceous/Paleogene mass extinction (K/Pg), the Paleocene/Eocene Thermal Maximum (PETM), Eocene hyperthermals, the Eocene/Oligocene transition (EOT), the Miocene Climate Optimum (MCO), the Pliocene peak warmth, and Ocean Anoxic events.

Policy of Mutual Respect.

We expect all faculty, staff, graduate students, and undergraduates will treat each other with respect and consideration.  Every member of the lab is valued for their contributions, opinions, and voices independent of race, ethnicity, gender/sexual orientation, national origin, religion, social background, or physical abilities.  We will not tolerate disrespect, belittlement, inappropriate jokes, or any negative comments about racial, ethnic, religious, gender/sexual preferences, or national group.  We acknowledge and appreciate our different backgrounds and perspectives and encourage free and open scientific discourse among lab participants, with all opinions respected. 

  1. Each member of our lab group contributes to the overall success of the lab’s mission and every effort will be made to ensure that opportunity is not hindered.
  2. Our mission is best carried out in an atmosphere where members at all levels value each other and treat each other with respect even in urgent and high-pressure situations.
  3. Leadership should be role models in promoting this atmosphere of mutual respect, while continuing to hold all lab members accountable for effective performance.
  4. All employees should be able to discuss issues of concern without fear those discussions will cause retaliation from any other lab member.

We encourage individuals who believe they are not being treated in accordance with the terms of this policy to bring their concerns to our attention or to the attention of the Chair, GPD, Student services, or the Office of Employment equity


Lab Research Assistant

We are always looking for motivated, responsible, and curious students who would like to be involved in our lab. No experience is required, but you must have a minimum GPA of 3.0, and be interested in Earth history, stratigraphic, or paleoceanographic research and willing to commit a consistent number of hours each week for at least one academic semester. Research assistants can become involved in all phases of the research process, including study design, data collection, data entry, and interpretation of the results. Our regular lab meeting, usually held every Friday, gives research assistants the chance to interact with the PI and graduate students in the lab, learn more about empirical research and emerging findings in stratigraphy, paleoceanography and Earth history.
