Effects of Trawling on Seamounts [PDF]
Oceanography, 2010 Trawling involves the towing of nets through the water or along the seafloor to sieve out fish and marine invertebrates. It is the most widely used method to catch fish throughout the world, and there are many variations in gear design and towing methods.

Getting to the Bottom of Trawling’s Carbon Emissions
Eos, 2021 A new model shows that bottom trawling, which stirs up marine sediments as weighted nets scrape the ocean floor, may be releasing more than a billion metric tons of carbon every year.

Angewandte Chemie, EarlyView.Mechanistic studies on model Cu─M/SiO2 catalysts (M = Zn, Ga, and In) reveal that promoters enable a formate spillover pathway from Cu to Mn+ (n = 2 or 3) sites. The promoter's electronic effect on formate bond strengths serves as a quantitative descriptor for activity and selectivity, balancing spillover dynamics with intermediate stabilization to ...

Catalytically Enhanced Near Room‐Temperature Hydrogen Sensing Using Pd‐ZnO Colloidal Crystals
Advanced Functional Materials, EarlyView.Pd‐decorated ZnO colloidal crystal monolayers demonstrate excellent performance across a wide hydrogen concentration range at 33°C, with high selectivity and reproducible device fabrication. The sensors show strong responses even at low‐ppm H2 concentrations and an ultra‐low detection limit of 82 ppb, indicating their suitability for diverse hydrogen ...

The value of bottom trawling in Europe
Ocean & Coastal ManagementAbstract Commercial bottom trawl and dredge fisheries are active across much of Europe, and their geographic footprint is extensive. More than half of seabed area is trawled every year in some parts of Europe. But these fisheries remain contentious; significant ecological and economic damages have been well documented. Yet, they remain a source

Advanced Materials, EarlyView.A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Novel Insights Into Gas Embolism in Sea Turtles: First Description in Three New Species
Frontiers in Marine Science, 2020 The recent finding of gas embolism (GE) and decompression sickness (DCS) in loggerhead sea turtles (Caretta caretta) in the Mediterranean Sea challenged the conventional understanding of marine vertebrate diving physiology.

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.

Density Dependent Catchability In Bottom Trawl Surveys
, 1997 No abstracts are to be cited without prior reference to the author.Fish form schools, layer or patches in which the individual fish's behaviour is not independent ofits neighbours movements. On the other hand, at low densities fish may have the freedom to actas single individuals independently of what other fish are doing.
