Comparative Study of FDA and Time Series Approaches for Seabed Classification from Acoustic Curves
(Springer Heidelberg, 2019-04)
Seabed classification in coastal environments is usually accomplished using multivariate methods applied to acoustic features from corrected or uncorrected echoes. This paper presents a comparative study of alternative ...
Trawl exposure and protection of seabed fauna at large spatial scales
(Wiley Blackwell Publishing, Inc, 2017-11)
Aim: Trawling is the most widespread direct human disturbance on the seabed. Knowledge of the extent and consequences of this disturbance is limited because large-scale distributions of seabed fauna are not well known. We ...
A sea bottom classification of the Robredo area in the Northern San Jorge Gulf (Argentina)
(Springer, 2021-02)
Benthic habitats are primarily determined by the nature of the substrate (i.e., the type of sediment or rock) and by the bathymetry (e.g., light availability, current, or waves exposition) both determining the viability ...
What can a low-cost fish-finder tell us about the seabed?
(Academic Press Ltd - Elsevier Science Ltd, 2018-12)
Low-cost non-scientific echosounders are commonly used for safety and other non-scientific purposes. These echosounders routinely record data which are rarely processed for later use, but which could provide interesting ...
Choosing best practices for managing impacts of trawl fishing on seabed habitats and biota
(Wiley Blackwell Publishing, Inc, 2020-03)
Bottom trawling accounts for almost one quarter of global fish landings but may also have significant and unwanted impacts on seabed habitats and biota. Management measures and voluntary industry actions can reduce these ...
Assessing bottom trawling impacts based on the longevity of benthic invertebrates
(Wiley Blackwell Publishing, Inc, 2019-05)
Bottom trawling is the most widespread human activity directly affecting seabed habitats. Assessment and effective management of the effects of bottom trawling at the scale of fisheries requires an understanding of differences ...
Estimating the sustainability of towed fishing-gear impacts on seabed habitats: a simple quantitative risk assessment method applicable to data-limited fisheries
(British Ecological Society, 2016-11)
Impacts of bottom fishing, particularly trawling and dredging, on seabed (benthic) habitats are commonly per-ceived to pose serious environmental risks. Quantitative ecological risk assessment can be used to evaluate ...
Trawl fishing impacts on the status of seabed fauna in diverse regions of the globe
(John Wiley & Sons Inc, 2020-08)
Bottom trawl fishing is a controversial activity. It yields about a quarter of the world´s wild seafood, but also has impacts on the marine environment. Recent advances have quantified and improved understanding of large-scale ...
Selection of indicators for assessing and managing the impacts of bottom trawling on seabed habitats
(Wiley Blackwell Publishing, Inc, 2020-04)
Bottom trawl fisheries are the most widespread source of anthropogenic physical disturbance to seabed habitats. Development of fisheries-, conservation- and ecosystem-based management strategies requires the selection of ...
Assessment of the impacts of shallow gas on taxonomic structure of benthic communities in Bahía Blanca estuary (Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2020-10-05)
Shallow biogenic gas deposits located in the surface of the seabed may affect abundance, diversity, biomass and structure of benthic communities. Nevertheless, the magnitude and responsible variables of this effect still ...
