Impact of bottom trawling on sediment biogeochemistry: a modelling approach [PDF]
Biogeosciences, 2021 Bottom trawling in shelf seas can occur more than 10 times per year for a given location. This affects the benthic metabolism, through a mortality of the macrofauna, resuspension of organic matter from the sediment, and alterations of the physical ...

Biogeochemical dynamics in a marine storm demonstrates differences between natural and anthropogenic impacts [PDF]
Scientific ReportsThis study explores the impact of a wind storm on sediment resuspension and marine biogeochemical dynamics. Additionally, the storm took place during an expedition researching bottom trawling, enabling the direct comparison of certain natural and ...

Effects of bottom trawling on fish foraging and feeding. [PDF]
Proc Biol Sci, 2015 The effects of bottom trawling on benthic invertebrates include reductions of biomass, diversity and body size. These changes may negatively affect prey availability for demersal fishes, potentially leading to reduced food intake, body condition and yield of fishes in chronically trawled areas.

Physical impact of bottom trawling on seafloor sediments in the German North Sea
Frontiers in Earth Science, 2023 Bottom trawling is a well-known global phenomenon and has significant physical impact on the seabed habitat, such as compression, displacement and mobilization of the sediment.

Bottom Trawling Threatens Future Climate Refugia of Rhodoliths Globally
Frontiers in Marine Science, 2021 Climate driven range shifts are driving the redistribution of marine species and threatening the functioning and stability of marine ecosystems. For species that are the structural basis of marine ecosystems, such effects can be magnified into drastic ...

Frontiers in Marine Science, 2022 It is estimated that within the UK exclusive economic zone (UK EEZ), 524 Mt of organic carbon (OC) is stored within seabed sediment. However, the stability and potential vulnerability of OC in these sediments under anthropogenic stressors, such as bottom

Turning the tide on bottom trawling [PDF]
Aquatic Conservation: Marine and Freshwater Ecosystems, 2015 Trawling is universally recognized as one of the most destructive fishing methods, causing irreversible damage through scraping large tracts of bottom habitats. These habitats then suffer from declines in ecosystem functions and services, and collapses in populations of trawled species. The plethora of studies on the unsustainable impacts of commercial

Frontiers in Marine Science, 2022 Submarine canyons are important conduits of sediment and organic matter to deep-sea environments, mainly during high-energy natural events such as storms, river floods, or dense shelf water cascading, but also due to human activities such as bottom ...

Limnology and Oceanography Letters, 2020 Bottom trawling and eutrophication are large stressors that are critically coupled. Here we show, using a before‐after control‐effect design, the significant reduction in denitrification as a result of experimental bottom trawling in a shallow coastal ...
