In that case attention could be focused on three or four Atolls w!iichare now inhabited, o)”are nmber of likely to be in the near future, and tkreDY ‘reduce t~le samples required snd the subsequent analytical costs. However, even to outiine a reduced program focused at only 3 or 4 specific Atolls will require Fore information or time at each Atoll and available support during the survey.
