Physical Disturbance by Bottom Trawling Suspends Particulate Matter and Alters Biogeochemical Processes on and Near the Seafloor

Frontiers in Marine Science, 2021
Bottom trawling is known to affect benthic faunal communities but its effects on sediment suspension and seabed biogeochemistry are less well described. In addition, few studies have been carried out in the Baltic Sea, despite decades of trawling in this

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 ...

Impacts of bottom trawling on benthic biogeochemistry in muddy sediments: Removal of surface sediment using an experimental field study.

Marine Environmental Research, 2021
Experimental benthic dredging was conducted in an unfished, muddy area in the Baltic Proper to mimic the impact of trawling by removing surface sediment, with a focus on benthic biogeochemical processes.

Trawling for Trolling: A Dataset

CoRR, 2020
The ability to accurately detect and filter offensive content automatically is important to ensure a rich and diverse digital discourse. Trolling is a type of hurtful or offensive content that is prevalent in social media, but is underrepresented in datasets for offensive content detection.

Comparing environmental metabarcoding and trawling survey of demersal fish communities in the Gulf of St. Lawrence, Canada

Environmental DNA, 2020
Biodiversity assessment is an important part of conservation management that ideally can be accomplished with noninvasive methods without influencing the structure and functioning of ecosystems.

Discards of Spanish trawler fleets operating in the Bay of Biscay in 2000

Scientia Marina, 2006
A stratified sampling programme by gear and port was carried out by observers on board vessels in 2000 to study the discard behaviour of trawler fleets operating off Spanish North Atlantic coasts. No relationship between discards in weight or numbers and

Small-Scale Patterns in the Distribution and Condition of Bamboo Coral, Keratoisis grayi, in Submarine Canyons on the Grand Banks, Newfoundland

Frontiers in Marine Science, 2019
Keratoisis grayi is one of the most abundant large gorgonian corals found off Newfoundland and Labrador, yet we know little regarding the factors influencing its distribution, abundance, and condition. We employed remotely operated vehicle (ROV) transect

Impact of bottom trawling on sediment biogeochemistry: a modelling approach

Biogeosciences, 2020
. 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 ...

Exploitation patterns of Octopus vulgaris in two Mediterranean areas

Scientia Marina, 2002
Exploitation patterns of the common octopus, Octopus vulgaris, in two Mediterranean areas were studied in three ports, two in the Thracian Sea (Greece, Eastern Mediterranean) and one in the Catalan Sea (Spain, Western Mediterranean).

Assessing the impact of trawling on benthic megafauna: comparative study of video surveys vs. scientific trawling

, 2021
Most studies about benthic community use small-scale sampling methods focused on the infauna such as grabs or box-corers. The benthic data collected by scientific trawl surveys in all European waters, in the frame of the Common Fishery Policy Data ...
