Tracking the impact of bottom trawling on benthic habitat status

open access: yesConservation Biology, EarlyView.
Abstract 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.

Interpolating Bathymetric Big Data for an Inland Mobile Navigation System

open access: yesInformation Technology And Control, 2018
Depth information is crucial in most navigational analysis and decision support implemented in existing inland navigation systems. Bathymetric data sets need to be preprocessed and converted into Digital Terrain Model by interpolation methods to provide different vector layers for Electronic Navigational Chart.

Integrating fossil data in ecological niche models to improve predictions of future habitat of Caribbean corals

open access: yesConservation Biology, EarlyView.
Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Smoothness priors modeling of seafloor bathymetric data

open access: yesGeophysical Research Letters, 1990
Multibeam bathymetric data is modeled from a Bayesian “smoothness priors” framework. Smoothness priors is a penalized likelihood‐nonparametric linear regression form of modeling and the bathymetry data are modeled one beam at‐a‐time. The method is applied to data previously analyzed in Goff and Jordan (1988) and Gilbert and Malinverno (1988).

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

open access: yesConservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

open access: yesConservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

High-Resolution Bathymetry by Deep-Learning Based Point Cloud Upsampling

open access: yesIEEE Access
Gridded bathymetric data are often used to understand seafloor topography; however, high-resolution data are rare. To obtain high-resolution gridded bathymetric data, the observations from which the data are derived must be densely measured.

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

open access: yesConservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...
