N1 - Funding Information: Some ikaite pictures were provided by Rosalind Rickaby (University of Oxford), Zunli Lu (University of Syracuse), Mark Belchier (British Antarctic Survey) and Alexey A. Krylov (St. Petersburg State University). Special thanks to Tracy Franks (University of Connecticut), Jörn Thiede (Geomar) and Gerold Wefer (Marum) for further comments and advice. Special thanks to local college museum curator Henrik Madsen (Fossil and Moclay Museum, Dk.) for samples and museum conservator Frank Osbæck for preparation. This work was partly funded by Slots - og Kulturstyrelsen, Denmark , with Dkr. 85.000 ( MFO20.2017-0004 ) and Museum Salling . Funding Information: We wish to thank Madeleine Vickers and an anonymous reviewer for their helpful comments, which much improved the manuscript. This paper would not have been possible without the help and courtesy provided by many honourable colleges who all share a fascination for the ikaite-glendonite enigma. Much credit must go first to Bjørn Buchardt (University of Copenhagen), Henrik Friis (Aarhus University), Peter Tandy (formerly Natural History Museum, London), Jochen Schlüter (Mineralogisches Museum der Universität Hamburg), Prof. Ole Johnsen (Museum Nat. Hist. Copenhagen) and Barbara Teichert (University of Munster). Thanks to private collectors in USA and Canada, Dana Morong, Don Hattie, Leo Scarpelli, John Cornish, David Joyce and Paul Burger. Samples provided by Prof. Paul Carr (Wollongong University) Prof. Sam Boggs Jr. (University of Oregon), Dr. Dan Larson (University of Memphis). The section on ikaite was only made possible by invaluable help from Erwin Suess, Hediemarie Kassen, Robert Spiehagen, Jens Greinert (all at Geomar, Germany), Matthias Zabel, Gerhard Bohrmann and Martin Kölling (Marum, Germany).

N2 - This paper presents a historical perspective of the discovery of, and aspects of, glendonite and ikaite, through the legacy of British mineralogists Douglas Shearman and Alec K. Smith. Much of the knowledge, literature review and synthesis presented in the following paper raises from the original work and discussions that these two key figures in mineralogy shared with the geological community both in the form of their official communications but also as informal discussions with the first author. Through our extensive review, we show that, while the link between ikaite and glendonite is now undeniable, questions remain.
