section. The Group also welcomes non-diving members who wish to be associated with its activities; they receive all publications, may attend all meetings but pay a reduced subscription. Of great importance is the Group's role in publishing information about exploration by members (and others) and developments in cave diving techniques. The Group produces a quarterly newsletter and a training manual. Sump Indices are available for each cave diving region (Somerset, Wales, Derbyshire & Northern) of Great Britain which summarise diving activities from Group members and non-members over many years. The newsletter is free to members and on sale to the public as are all the other publications. Members of the CDG are sometimes called upon to assist in cave rescue, particularly of cavers trapped by flood waters, such as the Alpazat cave rescue in Mexico in 2004 and the Tham Luang cave rescue in Thailand in 2019. Awards Mike ‘Fish’ Jeanmaire was Chairman of the CDG for thirty years. Following his death in November 2010 the ‘Fish Award’ was created. This is awarded annually to a member who has made a significant contribution to the CDG. Whilst the nature of the contribution is not precisely defined, the guiding principle is that the individual should have served the CDG rather than any other organisation or themselves. 2012 Fish Award: John Buxton 2013 Fish Award: John Cordingley 2014 Fish Award: Clive Westlake 2015 Fish Award: Andrew Ward 2016 Fish Award: Duncan Price 2017 Fish Award: David Ryall 2018 Fish Award: David Brock 2019 Fish Award: Rob Murgatroyd 2020 Fish Award: Helen Farr See also References External links CDG website Underwater diving training organizations Caving organisations in the United Kingdom Cave diving Diver organizations Underwater diving in the United Kingdom
