ImageReconstruction of El Niño Southern Oscillation using Ship's logbook data.

Supervisors: Dr Julie Jones and Professor Grant Bigg
Start Date: September 2014
Funding: ICERS (Ice and Climate Research at Sheffield)

Current Research:

The aim of my PhD research is to reconstruct El Niño Southern Oscillation (ENSO) using data from ships’ logbooks, 1750-1854. This reconstruction will extend the ENSO record further back than the instrumental-based Southern Oscillation Index, which extends back to 1876. The data from ships’ logbooks is a valuable source of information for climatic research as it contains daily and sub-daily information on variables including wind speed and direction, temperature and pressure. This research uses data digitised through projects including Climatological Database of the World’s Oceans (CLIWOC) and from English Easy India Company (EEIC) archives. The historical association between ENSO and the onset of the Indian summer monsoon is also being investigated along with comparisons of this relationship simulated in global climate models.

Research interests:

  • Climate Variability
  • Tropical Climate
  • Historical Climatology
