IAS Regional Correspondents are IAS Members who have volunteered to act as a representative between sedimentologists in their host region and the IAS. Each region (country, country region) with more than 5 members or regions indicated by the IAS Bureau can have a Regional Correspondent, appointed by the IAS President after recommendation by the Bureau in consultation with the sedimentology society / association / group of the region concerned.
Regional Correspondent tasks include:
- They inform the General Secretary of sedimentological activities within their particular country
- They assist the IAS society in recruiting members within their particular country
The mandate of the Regional Correspondents terminates at each 4-Yearly General Assembly. Regional Correspondents are eligible for reappointment for only one additional term.
If you know of any sedimentology events going on in your region then please get in touch with your Regional Correspondent and let them know (active members only, through member profile). Similarly, if your region lacks a Regional Correspondent and you would like to propose an IAS Member (Full or Student), or yourself, for this position then please contact the IAS.
