ABSTRACT Aim We assess the role of spatial distance and depth difference in shaping beta diversity patterns across abyssal seascape regions. measured decrease faunistic similarity northeast Pacific seafloor, to test whether species turnover rates differ between deep shallow‐abyssal biogeographical provinces these vary functionally or taxonomically different biotic groups. Location Abyssal NE Ocean. Time Period Present. Major Taxa Studied Benthic Invertebrates (13 Phyla). Methods examined...
Abstract We set out to characterize the fine‐scale processes acting on interannual dynamics of deep‐sea vent fauna by using a novel approach involving 5‐yr time series 3D photogrammetry models acquired at Eiffel Tower sulfide edifice (Lucky Strike field, Mid‐Atlantic Ridge). Consistently, with overall stability edifice, total mussel cover did not undergo drastic changes, suggesting that they have been climax stage for least 25 yr based previous data. Successional patterns showed consistency...
Visual localization plays an important role in the positioning and navigation of robotics systems within previously visited environments. When visits occur over long periods time, changes environment related to seasons or day-night cycles present a major challenge. Under water, sources variability are due other factors such as water conditions growth marine organisms. Yet, it remains obstacle much less studied one, partly lack data. This paper presents new deep-sea dataset benchmark...
Food webs and trophic interactions provide a measure of ecosystem function have been highlighted as an important element for environmental baselines impact assessments. Stable isotopes long used in the deep sea means to explore summarize food webs, especially chemosynthetic ecosystems, where there may be multiple sources primary production with distinctive isotopic compositions. Hydrothermal vents Manus Basin targeted mining and, if proceeds, vent will altered. Here we describe pre-mining...
Methane seeps provide a variety of ecosystem services, including the provision complex habitat structures and high levels primary production, which can act as trophic support to non-seep-endemic species in an otherwise food-limited environment. The discovery hundreds on US Atlantic margin, ranging depth from ~50 1700m, provides opportunity assess depth-related differences seep-associated communities. Here, we use photo transects characterize megafaunal communities at six along comparing...
The increasing availability of seabed images has created new opportunities and challenges for monitoring better understanding the spatial distribution fauna substrata. To date, however, deep-sea substratum classification relies mostly on visual interpretation, which is costly, time-consuming, prone to human bias or error. Motivated by success convolutional neural networks in learning semantically rich representations directly from images, this work investigates application state-of-the-art...
Imaging is increasingly used to capture information on the marine environment thanks improvements in imaging equipment, devices for carrying cameras and data storage recent years. In that context, biologists, geologists, computer specialists end-users must gather discuss methods procedures optimising quality quantity of collected from images. The 4 th Marine Workshop was organised 3-6 October 2022 Brest (France) a hybrid mode. More than hundred participants were welcomed person about 80...
Alvinocaridid shrimp occurring in dense assemblages close to vigorously venting orifices are characteristic of many vent fields on the Mid-Atlantic Ridge, Central Indian and Mid-Cayman Rise. Episymbiotic bacteria these exposed fluids enriched inorganic nutrients (carbon dioxide, sulfide) that, together with dissolved oxygen surrounding seawater, sustain autotrophic growth supply nourishment shrimp. Enigmatically, conspecific may also be found sparsely distributed periphery a field, where...
Recent advances in deep-sea exploration with underwater vehicles have led to the discovery of vertical environments inhabited by a diverse sessile fauna. However, despite their ecological importance, habitats remain poorly characterized conventional downward-looking survey techniques. Here we present high-resolution 3-dimensional habitat map cliff hosting suspension-feeding community at flank an glacial trough Greenland waters Labrador Sea. Using forward-looking set-up on Remotely Operated...
Leading deep-sea research expeditions requires a breadth of training and experience, the opportunities for Early Career Researchers (ECRs) to obtain focused mentorship on expedition leadership are scarce. To address need in expeditionary science, Crustal Ocean Biosphere Research Accelerator (COBRA) launched 14-week virtual Master Class with both synchronous asynchronous components empower students skills tools successfully design, propose, execute oceanographic field research. The offered...
Artificial fish passes are often the most effective solution to restore ecological continuity of a dammed river. Such pass can be built for specifically targeted species, based on existing knowledge its swimming capacity and behaviour. Usually, wider range possible species present in river may use pass. In study, vertical slot has been designed salmonid (namely Atlantic salmon Salmo Salar). This layout was initially tested using scale model where juvenile were introduced. The study now...
Imagery has become one of the main data sources for investigating seascape spatial patterns. This is particularly true in deep-sea environments, which are only accessible with underwater vehicles. On hand, using collaborative web-based tools and machine learning algorithms, biological geological features can now be massively annotated on 2D images support experts. other geomorphometrics such as slope or rugosity derived from 3D models built structure motion (sfm) methodology then used to...
For the past decades, photogrammetry has been increasingly used for monitoring spatial arrangement or temporal dynamics of submerged man-made structures and natural systems. As remains a nascent technique data collection in underwater environment, acquisition workflows have evolved constrained by specific methodological practicalities (e.g. euphotic environments vs. deep-sea waters). The annual GeoHab conference gathers world-wide range scientists interested mapping is, therefore, an...
