This event has a limited number of places, and therefore we will require an application prior to registration. All applications will be reviewed after the application deadline. We will select the applicants based on the strength of their submission, including their desire to attend the event and the relevance of their research to speleothem science.


S4 2023 will consist of three days of lectures and workshops from experts in the field of speleothem science at the Institute of Geosciences at the University of Sao Paulo, Brasil. Participants will also get the chance to present their own research to fellow participants and the experts during poster sessions.​ This will be followed by a 3-day field trip to PETAR (Parque Estadual Turistico do Alto Riberia), a beautiful region renowned for its caves.

Preliminary lecture topics (subject to change)

  • Stable isotopes (oxygen and carbon)

  • Trace elements

  • Speleothem formation (in the field)

  • Cave monitoring + speleothem sampling (in the field)

  • Dating (U and Pb)

  • Speleothems and climate models

  • Paleotemperature

  • Karst geomorphology and hydrology (in the field)

Preliminary workshops (subject to change)

  • Speleothem petrography

  • Age-depth modeling

  • Time series analysis

  • Professional development panel

  • Cave photography (in the field)



If admitted, applicants will be asked to pay a registration fee. The registration fee will include lodging, some meals and snacks, as well as the field trip. Participants will need to secure funding for travel to and from Brasil and some of their meals during the event.


We do not currently have an estimate for the registration fee. As a very rough estimate, the fee for the last S4 in Romania was ~$550 USD. We are trying to keep the registration fee as low as we can.

Financial Support

The S4 committee is pleased to announce that we have secured funds to provide financial support to our attendees. Financial aid applications are not yet open, but applicants can indicate their intention to apply for aid on the general application form. More details coming soon.
