Multibeam bathymetry from an Autonomous Underwater Vehicule (AUV) - Pointe-des-Monts (2019-2020)

Patrick Lajeunesse & Alexandre Normandeau
Using an autonomous underwater vehicle (HUGIN) equipped with an EM2040 multibeam echosounder, submarine canyons and channels offshore Pointe-des-Monts were surveyed in 2019 and 2020. This survey aimed at identifying the fine-scale morphological variability of turbidity current bedforms on the modern seafloor. This project was funded by Réseau Québec-Maritime.

Data from: Shale-hosted biota from the Dismal Lakes Group in Arctic Canada supports an early Mesoproterozoic diversification of eukaryotes

Corentin C. Loron, Galen P. Halverson, Robert H. Rainbird, Tom Skulski, Elizabeth C. Turner & Emmanuelle J. Javaux
The Mesoproterozoic is an important era for the development of eukaryotic organisms in oceans. The earliest unambiguous eukaryotic microfossils are reported in late Paleoproterozoic shales from China and Australia. During the Mesoproterozoic, eukaryotes diversified in taxonomy, metabolism and ecology, with the advent of eukaryotic photosynthesis, osmotrophy, multicellularity, and predation. Despite these biological innovations, their fossil record is scarce before the late Mesoproterozoic. Here, we document an assemblage of organic-walled microfossils from the 1590-1270 Ma Dismal...

Bathymétrie multifaisceaux des pentes deltaïques dans l'estuaire du Saint-Laurent (2020)

Alexandre Normandeau, Jean-Carlos Montero-Serrano & Audrey Limoges
Le projet est issue d’un financement du Réseau Québec Maritime (RQM) et MEOPAR (https://meopar.ca/meopar-and-rqms-first-joint-projects-explore-risk-assessment-and-response-in-the-st-lawrence-system/) et porte sur les risques naturels associés à la remobilisation des sédiments sur la Côte-Nord du Saint-Laurent. Le projet vise principalement à évaluer la distribution des risques naturels sous-marins sur les deltas marins de la Côte-Nord. Il s’agit d’une collaboration entre l’Université du Québec à Rimouski, l’Université du Nouveau-Brunswick, la Commission géologique du Canada, l’Université Laval et l'Université Dalhousie.

Data from: A review of the evolution, biostratigraphy, provincialism and diversity of Middle and early Late Triassic conodonts

Yanlong Chen, Leopold Krystyn, Michael J. Orchard, Xu-Long Lai & Sylvain Richoz
The taxonomy, diversity, evolutionary lineages, and stratigraphical distributions of Middle and early Late Triassic conodonts are reviewed and re-evaluated. Twenty-five genera are recognized in the Middle and early Late Triassic, including a new genus cited in open nomenclature. Of these, 24 genera are assigned to two families and seven subfamilies. The family Gondolellidae consists of the subfamilies Cornudininae, Epigondolellinae, Neogondolellinae, Novispathodinae, Paragondolellinae and Pseudofurnishiinae. The family Gladigondolellidae is monotypic, consisting of the subfamily Gladigondolellinae. The...

Data from: Microbial consortia controlling biogenic gas formation in the Qaidam Basin of western China

Yanhua Shuai, Shuichang Zhang, Stephen E. Grasby, Weiguo Hou, Zhuoheng Chen, Ling Huang, Mingqing Kui, Yirui Xu & Yang Wang
Knowledge of what controls the activity of subsurface microbial communities is critical for assessing and managing biogenic methane resources. In this study, 19 formation waters and five gas samples were collected at depths of 800 to 1900 m from Quaternary biogenic gas fields of the Qaidam Basin, China. The formation waters were brines with chloride (Cl) concentrations from 1200 to 2700 mM. Bacterial 16S rRNA gene copies ranged from 3.75 × 104 to 2.23 ×...

Data from: Resilience of peatland ecosystem services over millennial timescales: evidence from a degraded British bog

Graeme T. Swindles, Paul J. Morris, Jane Wheeler, Mark Smith, Karen L. Bacon, T. Edward Turner, Alistair Headley, Jennifer M. Galloway & Mark W. Smith
1. Many peatland ecosystems in Europe have become degraded in the last century owing to the effects of drainage, burning, pollution, and climate change. There is a need to understand the drivers of peatland degradation because management and restoration interventions can affect the natural ecohydrological dynamics of such sensitive environments, and are expensive. However, if given enough time peatlands may have the ability to recover spontaneously without deliberate action. 2. We use a detailed multiproxy...
