and evaluation efforts in the post-impact studies be considered. Data from
a previous cruise should be fully available before the subsequent one.
The time calculations given in table 4 are restricted to sample
sorting and limited taxonomic analyses at genus level, but exclude all of the
following tasks:
?? The total pre-baseline study,
?? All work at sea,
?? Data analyses,
?? Consideration of the Foraminifera,
?? Sedimentological and geochemical studies,
?? Project co-ordination,
?? Training of technical staff, and
?? Reporting and publication.

Calculation of minimum time required for biological sample and image
processing.
The above calculation of work time is included in this paper because
most projects -- including the DISCOL/ATESEPP investigations – eventually
run short of time and funds, ultimately endangering some of the results
hoped for or anticipated.
The calculations presented in the preceding paragraphs are based
on the material and experience available from DISCOL/ATESEPP; thus, the
recommendations on sample numbers are suitable only for this specific
