Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

The impacts of hydraulic clamming in shallow water and the importance of incorporating anthropogenic disturbances into habitat assessments

Aquatic Living Resources, 2020
Hydraulic dredging for shellfish is known to create some of the highest levels of disturbance, affecting the benthic microfaunal community and the physical characteristics of the substrate.

Benthic Habitat Mapping from Seabed Images using Ensemble of Color, Texture, and Edge Features [PDF]

International Journal of Computational Intelligence Systems, 2013
In this paper we present a novel approach to produce benthic habitat maps from sea floor images in Derwent estuary. We have developed a step–by–step segmentation method to separate sea–grass, sand, and rock from the sea floor image. The

A predictive approach to benthic marine habitat mapping: Efficacy and management implications

Marine Pollution Bulletin, 2018
The availability of marine habitats maps remains limited due to difficulty and cost of working at sea. Reduced light penetration in the water hampers the use of optical imagery, and acoustic methods require extensive sea-truth activities. Predictive spatial modelling may offer an alternative to produce benthic habitat maps based on complete acoustic ...

A machine learning assisted method for rapidly annotating benthic megafauna in large volumes of marine imagery

Limnology and Oceanography: Methods, EarlyView.
Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...

Confirmation of hard-substrate predictions in the abyssal Vema Fracture Zone

Frontiers in Marine Science
Hydroacoustic mapping has recently challenged the long-held view of a uniform abyssal seafloor by predicting substantial habitat heterogeneity in this environment.

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Mapping the Marine Environment Through a Cross-Cultural Collaboration

Frontiers in Marine Science, 2020
There is a growing emphasis on formally recognizing the connection to the marine environment of Indigenous peoples and the traditional ecological knowledge (TEK) these strong connections cultivate.

Assessing the effectiveness of surrogates for conserving biodiversity in the Port Stephens-Great Lakes Marine Park [PDF]

, 2015
University of Technology Sydney. Faculty of Science.The effectiveness of marine protected areas (MPAs) in conserving biodiversity depends, in part, on which areas are chosen for protection and how these areas represent the true biodiversity of the ...
