Atmospheric CO2 emissions and ocean acidification from bottom-trawling [PDF]
Frontiers in Marine ScienceTrawling the seafloor can disturb carbon that took millennia to accumulate, but the fate of that carbon and its impact on climate and ecosystems remains unknown.

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 ...

Bottom-trawling along submarine canyons impacts deep sedimentary regimes. [PDF]
Sci Rep, 2017 Many studies highlight that fish trawling activities cause seafloor erosion, but the assessment of the remobilization of surface sediments and its relocation is still not well documented.

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 ...

Effects of bottom trawling and hypoxia on benthic invertebrate communities [PDF]
, 2022 Marine benthic habitats in continental shelf regions are increasingly impacted by hypoxia caused by the combination of eutrophication and climate warming.

Tracking the impact of bottom trawling on benthic habitat status. [PDF]
Conserv BiolAbstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

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 ...

Organic biomarkers in deep-sea regions affected by bottom trawling: pigments, fatty acids, amino acids and carbohydrates in surface sediments from the La Fonera (Palamós) Canyon, NW Mediterranean Sea [PDF]
Biogeosciences, 2013 Deep-sea ecosystems are in general adapted to a limited variability of physical conditions, resulting in high vulnerability and slow recovery rates from anthropogenic perturbations such as bottom trawling.

Estimating sensitivity of seabed habitats to disturbance by bottom trawling based on the longevity of benthic fauna. [PDF]
Ecol Appl, 2018 Bottom fishing such as trawling and dredging may pose serious risks to the seabed and benthic habitats, calling for a quantitative assessment method to evaluate the impact and guide management to develop mitigation measures.
