“So what we can mainly see of these organisms is the bioturbation structures they produce.” As the organic material degrades and the oxygen decreases in the sediment, invertebrates take ...

Among the myriad creatures that populate our ocean, some stand out as having an outsized impact on the marine environment—shaping and maintaining habitats that themselves sustain countless other forms ...

Macrofauna’s mixing of sediment, or bioturbation, typically affects parameters like sediment permeability, grain size, and erodibility (Volkenborn et al., 2009; Kristensen et al., 2013; Harris et al., ...

X-ray scanning was used to examine the structure of the sediment and combined ... More information: Jussi Hovikoski et al, Bioturbation in the hadal zone, Nature Communications (2025).

Organisms in the deep sea rely on gravity flows to lay down sediment and then make burrows beneath the seafloor, according to a new study.

Meanwhile, Micro-CT scanning (SkyScan 1172 X-ray; State Key Laboratory of Biogeology and Environmental Geology) was employed to reconstruct the internal structures of stems ... not only results in ...
