The Agulhas Current Time-Series Experiment (ACT)
The ACT project was a series of three expeditions to South Africa led by Prof. Lisa Beal. I joined the project after the field work, and focused on the analyses of the moored observation data generated by the project. I have contributed so far to three publications:
- Leber, G. M., L. M. Beal and S. Elipot (2016), Classification of Upwelling Events inshore of the Agulhas Current at 34ºS, in revision for J. Phys. Oceanogr., Sept. 2016

Monitoring and studying the lower limb of the North Atlantic Meridional Overturning Circulation from in-situ data
I worked at the UK National Oceanography Centre in Liverpool, UK, on mooring observations at several latitudes of the return and deep flow of the North Atlantic Meridional Overturning Circulation (AMOC). The general topic of my research was to understand the variability of the MOC on intra-annual to inter annual time scales. The name of this program funded by the UK NERC is RAPID WAVE from the Rapid Climate Change programme. I have contributed to four peer-reviewed publications for this project:
- Elipot, S. et al. (2016), Observed basin-scale response of the North Atlantic Meridional Overturning Circulation to wind stress forcing, submitted to J. Clim., Sept. 2016
- Elipot, S., E. Frajka-Williams, C. Hughes and J. Willis (2014), The Observed North Atlantic Meridional Overturning Circulation, its Meridional Coherence and Ocean Bottom Pressure, J. Phys. Oceanogr., 44, 517-537, doi:10.1175/JPO-D-13-026.1

What is the polarization of ocean currents?
This question was the central theme of my postdoctoral research project which was first funded by a postdoctoral fellowship from the National Research Council of the US National Academies. I conducted this research at AOML under the advising of Dr. Rick Lumpkin. The second year of this project was funded by the Cooperative Institute for Marine and Atmospheric Studies of the University of Miami, Miami, Florida, USA. This project led to three publications:
- Elipot, S. and R. Lumpkin (2008), Spectral description of oceanic near-surface variability, Geophys. Res. Lett., 35, L05606, doi:10.1029/2007GL032589.

The Southern Ocean response to wind forcing
This general theme was the underlying motivation of the PhD project at Scripps Institution of Oceanography at the University of California, San Diego. I was advised by Prof. Sarah Gille. This project led to two peer-reviewed publications in addition to my PhD thesis:
- Elipot, S. and S. T. Gille (2009), Estimates of wind energy input to the Ekman layer in the Southern Ocean from surface drifter data, J. Geophys. Res., 114, C06003, doi:10.1029/2008JC-005170.
