A Modified Gear Removal Index (GRI) Method to Support the Management of Abandoned Fishing Gear on Coralligenous Reefs

Fisheries Management and Ecology, EarlyView.
ABSTRACT Abandoned, Lost or otherwise Discarded Fishing Gears (ALDFG) have significant negative effects on marine ecosystems. In the Mediterranean Sea, the impact of ALDFG is particularly relevant on coralligenous reefs. The management of ALDFG focuses primarily on their removal, however this type of intervention may potentially damage the habitat, so ...

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

Journal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

Geomorphological Classification of the Benthic Structures on a Tropical Continental Shelf

Frontiers in Marine Science, 2019
Geomorphological research offers a valuable first step to understand the complexity of seafloor patterns that are likely to support particular fauna, thereby providing value for future targeted studies on benthic communities and habitats.

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

Journal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Exploiting Evolution for an Adaptive Drift-Robust Classifier in Chemical Sensing [PDF]

, 2010
Gas chemical sensors are strongly affected by drift, i.e., changes in sensors' response with time, that may turn statistical models commonly used for classification completely useless after a period of time.

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

The Hyper-Angular Cube Concept for Improving the Spatial and Acoustic Resolution of MBES Backscatter Angular Response Analysis

Geosciences, 2018
This study presents a novel approach, based on high-dimensionality hydro-acoustic data, for improving the performance of angular response analysis (ARA) on multibeam backscatter data in terms of acoustic class separation and spatial resolution.
