THE 6TH DEEP-SEA BIOLOGY SYMPOSIUM IN COPENHAGEN rlrst an apology, this is not a review of the proceedings, if that is whst you want then please borrou a copy of the programme from a friend. Rathey, this is a collection of thoughts on the meeting as a whole; perhaps- useful to those who will organise the nest meeting, or in starting a discussion on what we think our meetings should be like. Be certain that this meeting was an undoubted success both scientificalll- and socially. The organisers deserve a great vote of thanks for their ef- forts. Torben Wolff of course merits special mention for his leadership, at all times leading from the front he made sure ue missed nothing. Ke are also grateful to the three other organisers, Ole Tendal, Jorgen Kirkegaard and Reinhardt ?l. Kristensen, as well as to the very efficient secretaries and students for their assistance. The success of the meeting o~edniuch to its atmosphere. Informalit)- and openness are adrnirablequalities, but they .also bring with them other useful i xiits. Tinieliness is iniportant to a meeting of this type. By emphasising the iiovel the meeting beconles more accessible to the newcomer. The availabi l 'l tl- ( f the meeting to all, particularlq- students, \;as a question raised briefil- Copenhagen. It is perhaps mainly the responsibilitb- of ~uper\~isorsto ei1- ( Jre that students are recruited to these meetings [as larvae are-entrained in the uake of seaniounts, Mul.lineaux]. Judging by the size of some student parties at the meeting this is certainly being done.with some success. The general accessibility of the meet- ing can perhaps be gauged by the ratio of attending authors to total' participants: 75% [a rather higher rate than spawners in an orange roughy aggregation, Newton] . The majority had single authorships, though many c.30% had t~o,often on both talk and poster {a non-random pairing? cf some eclzinoids, Young] . It should come as 110 surprise that the prize for the niaxiniuni authorships, at seven a piece, goes to the now immortal pairing - of Gage & Tyler (available at all good bookshops). Posters were given some prominence at the meeting, about 1/3 of all contribu- tions. Presenting posters remains a pro- blem ; a1though on display throughout the meeting and given their own specific hour, the instinct of participants to feed during the available 'free-time' Kas strong [a need not lost on some deep-sea echinoids, Campos]. One other potential problem relates to video and/or slide dominated presentations. With a number of very- notable excep- tions, the science behind some of these presentations got a little lost in ' the welter of visual images and species names [even more names are to be expected through the use of genetics, France, Vrijenhoek]. The timetabling and forum for all of these visually-based presentations should not over-tax their potential audience [S tress, Hawkins] . The key to the success of the Copenhagen meeting, apart from the efforts of the organisers and participants, was its diversity. Biodiversity may be an increasing concern for the future [Paterson], maintaining or enhancing the diversity achieved in Copenhagen should certainly concern us. Participants from 18 countries attended the meeting. The democratic selection of the next venue hopefully indicates that it will be similarly accessible. Topic rich- ness was high, from taxonomy [Dahms] to technology [Bagley]. Size diversity -[the importance of large rare organisms, Gerlach] in the presentations so helped; introductory talks to larger projects [DEEPSEAS and DISCOL, Rice and Thiel] and the more novel techniques [molecular biology, Felbeck] i 'ed understanding and allo~edsubsequent speakers to proceed quickly to trieir results. ~erhapsonly one element was missing from the habitat mosaic [: 1- grove] of this meeting - the open patch - the chance for the opportunistic recru2.tment of minds and bodies. Brian Bett IOSDL The Symposium was attended by a total of 141 participants from altogether 18 countries: Germany 31; UK 26; USA 22; Denmark 20; France and Russia 10; Japan 3; Australia, Belgium, Canada, Greece, Israel, Norway, Spain, and Sweden 2 each; Austria, Iceland, and Ireland 1 each.
