| 1. Scope |
|
1.1 This practice covers the procedures for obtaining qualitative bottom sample of macroinvertebrates inhabiting sandy, cobble, rubble stone, and similar substrates. 1.2 The sampler should not be used in critical quantitative work that is to be compared with results of other areas and is recommended as a reconnaisance sampler only. 1.3 This device is used primarily in marine waters and deep lakes. 1.4 For the advantages and limitations of selecting grab sampling devices, see Guide D4387. 1.5 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautions, see Section 5. |
