High resolution mapping of sediment organic matter from acoustic reflectance data [PDF]

, 2011
Spatial mapping of the marine environment is challenging when the properties concerned are difficult to measure except by shore-based analysis of discrete samples of material, usually from sparsely distributed sites.

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Enhancing seabed sediment classification with multibeam echo-sounding and self-training: a case study from the East Sea of South Korea

Frontiers in Earth Science
IntroductionAccurate classification of seabed sediments is essential for marine spatial planning, resource management, and scientific research. While direct sampling yields precise sediment information, it is costly and spatially limited.

Ferromanganese nodules and micro-hardgrounds associated with the Cadiz Contourite Channel (NE Atlantic): Palaeoenvironmental records of fluid venting and bottom currents [PDF]

, 2012
Ferromanganese nodule fields and hardgrounds have recently been discovered in the Cadiz Contourite Channel in the Gulf of Cadiz (850–1000 m). This channel is part of a large contourite depositional system generated by the Mediterranean Outflow Water ...

Opportunities for targeted, small‐scale law reform in marine and coastal restoration

Restoration Ecology, EarlyView.
Across the globe, law reform is being considered as a mechanism to support, guide, and encourage the upscaling of ecological restoration. While high‐profile examples like the European Nature Restoration Law show the value of large‐scale law reform, this scale of law reform will not be feasible or politically tractable everywhere.

The source‐to‐sea nexus between water and ocean law: An international and EU perspective

Review of European, Comparative &International Environmental Law, EarlyView.
Abstract The source‐to‐sea (S2S) approach provides a systemic framework for analysing the governance of naturally interconnected freshwater and marine ecosystems. This paper examines the extent to which the S2S approach is reflected in key international and EU water and ocean law instruments, as well as the legal and governance implications of said ...

Benthic habitat mapping in the Olympic Coast National Marine Sanctuary: Classification of side scan sonar data from survey HMPR-108-2002-01: Version I [PDF]

, 2006
In September 2002, side scan sonar was used to image a portion of the sea floor in the northern OCNMS and was mosaiced at 1-meter pixel resolution using 100 kHz data collected at 300-meter range scale.
