1 Scope

This standard determines the marine sediment gap biological investigation of the basic requirements established by the sediment, suspended solids, foraminifera, ostracods, put

Bursts, sedimentary diatoms, coccolithiasis, sedimentary pollen, benthic viruses, benthic microorganisms (including bacteria, archaea and fungi), benthic microalgae, primitive benthic movements

Objects, small benthic animals and other investigation of the general provisions and methods.

This standard applies to coastal areas, shallow seas and deep sea offshore and distant seas of different marine benthos survey.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Marine sediment

Weathering products of parent rocks (magmatic rocks, metamorphic rocks, pre-existing sedimentary rocks) under the influence of the surface crustal geology, biogenic materials, volcanoes

The original materials of matter, cosmic matter and so on have been loose, unconsolidated on the coast or the seafloor after being transported, settled or precipitated

Accumulation.

3.2 Sedimentary rock

It is one of the three major types of rocks that make up the lithosphere (the other two are magmatic rocks and metamorphic rocks). It consists of the parent rock (Or any pre-rock) weathering products, biogenic materials, volcanic materials, cosmic materials and other raw materials after the removal of the role of sedimentation

And sedimentary diagenesis and the formation of rocks.

3.3 Sediment interstitial biota

All benthic life forms that inhabit or deposit in the interstices between sediment particles.

Notes include marine microorganism, benthicvirus, microbenthos, miniature and small

Type benthic metazoan (micro-and meiobenthicmetazoa) and so on. From the individual size, marine sediment gap bio-covers a particle size of less than 0.2 µm (Femto-grade) of 0.2 µm to 2 µm, pico-order of 0.2 µm to 2 µm, nano-order of 2 µm to 20 µm and micro

Micro-level single-cell benthos and meio-level benthic metazoans.
