Sentence examples for ambient sediments from inspiring English sources

It is deposited above an erosional unconformity, contains abundant shell fragments, and is generally poorly sorted and embedded within ambient sediments.

Recolonization proceeded via a gradual increase in the abundance of those taxa present in ambient sediments rather than via a distinct successional sequence.

No consistent quantitative or qualitative differences were detected among clusters of ambient sediment samples taken less than 0·5 m apart.

Sites for the experimental deposition of terrestrial sediment were located along a gradient in wave exposure, with only limited variation in immersion times (30 min) and ambient sediment particle sizes (predominantly fine sand).

As the macrofaunal assemblage in the ambient sediment and the control plots was dominated by the common cockle Cerastoderma edule, this species was used in an additional mesocosm experiment.

As such, macrofaunal colonisation of food-enriched patches generally results in initially higher abundances and lower diversity compared to the ambient sediment e.g. [9], [21] [23]).Nematodes may also recolonise and reach background densities within hours or days after disturbance [24] [26].

BTBPE has been detected in several environmental compartments including ambient air, sediments, and bird eggs, as well as in household dust collected in the U.S., Europe, and New Zealand.

Here, we use the quantitative polymerase chain reaction (q-PCR) to investigate temporal variation in the abundance of specific bacterial and archaeal genes representing key N-cycling functional guilds within sediment samples taken from the walls of U. deltaura burrows in comparison with their abundances within ambient surface sediment samples.
