ISO 16665:2014为海水中潮下软底大型动物样本的定量收集和处理提供了指南。
ISO 16665:2014涵盖:a)抽样程序的开发;b)取样设备的要求;c)现场取样和样品处理;d)分类和物种鉴定;e)收集和处理的材料的储存。
ISO 16665:2014没有具体解决以下问题,尽管一些要素可能是适用的:生物测定子采样;深水(>750米)或近海取样;原位动物研究,例如再定殖测定;在取样装置中捕获的非底栖生物;河口采样;潮间带采样;小型动物取样和分析;通过挖泥船和雪橇取样;自给式水下呼吸器(水肺)采样;统计设计。
定位的准确性由地理区域、使用的设备和测量目标决定。
ISO 16665:2014 provides guidelines on the quantitative collection and processing of subtidal soft-bottom macrofaunal samples in marine waters.
ISO 16665:2014 encompasses: a) development of the sampling programme; b) requirements for sampling equipment; c) sampling and sample treatment in the field; d) sorting and species identification; e) storage of collected and processed material.
ISO 16665:2014 does not specifically address the following, although some elements may be applicable: bioassay sub-sampling; deep water (>750 m) or offshore sampling; in situ faunal studies, e.g. recolonization assays; non-benthic organisms caught in the sampling device; estuarine sampling; intertidal sampling; meiofaunal sampling and analysis; sampling by dredge and sledge; self-contained underwater breathing apparatus (SCUBA) sampling; statistical design.
Accuracy of position fixing is determined by the geographical area, equipment used and survey objective.
