Mapping the shallow marine benthic habitats of Rottnest Island, Western Australia
, 2007 The introduction of new, high resolution hyperspectral sensors has led to growing interest in the development of techniques to utilise data from these instruments for mapping the shallow marine environment.

Rapid Assessment of Intertidal Wetland Sediments
, 2012 Urbanization of coastal areas poses a severe threat to ecologically valuable intertidal wetlands. This paper presents a pragmatic approach called Rapid Assessment for Intertidal Wetland Sediments (RAITWS) for evaluating the sediment quality of intertidal

Deep blueprint: A literature review and guide to automated image classification for ecologists
Journal of Animal Ecology, EarlyView.A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Benthic nitrogen fixation in oxygen minimum zones
, 2016 The distribution and magnitude of benthic N2 fixation in OMZs, and its relevance for the community inhabiting these sediments was investigated. A possible coupling to sulfate reducers was determined by rate measurements of N2 fixation and sulfate reduction, as well as by molecular analysis in the respective environment. In sediments of the Peruvian OMZ,

300 Years of Degradation in Wales Estuaries and Coasts
Natural Resources Forum, EarlyView.ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Integrative Zoology, EarlyView.The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Cautionary Tales for Science‐Based Policy in Deep‐Sea Mining Governance
Global Policy, EarlyView.ABSTRACT This article examines how low‐certainty scientific claims permeate high‐stakes policy debates before rigorous validation. Using deep‐sea mining governance as a focal domain, the study traces high‐visibility narratives, including the “dark oxygen” hypothesis, radioactive risks of polymetallic nodules, projected impacts of sediment plume ...
