CAMBIOS Tomography data: classification of arrival sequences

[Lien vers la fiche source] This dataset is a product that results from the classification of arrival sequences of tomography data collected in the Canary basin. An ensemble of predictions of arrival sequences corresponding to different ocean states is generated and classes with similar characteristics are defined. The observed sequences are then related to a particular class using a simple Euclidian distance. Finally the time evolution of the vertical sound speed and salinity profiles averaged along the tomography pair is produced.

See the map attached to the dataset for more details.
Population-specific variations of the genetic architecture of sex determination in wild European sea bass Dicentrarchus labrax L.

[Lien vers la fiche source] Among the different sex determination modalities exhibited by fish species, polygenic sex determination (PSD) is supposedly unstable, with genetic and environmental components that may vary between populations exposed/adapted to different environments. European sea bass (Dicentrarchus labrax) is an interesting model, combining both a PSD system and a genetic subdivision into an Atlantic and a Mediterranean lineage, with genetic substructures within the Mediterranean Sea. We produced experimental progeny crosses (N = 927) from broodstock sampled in four wild populations (North Atlantic, NAT; Western Mediterranean, WEM; North-Eastern Mediterranean, NEM; South-Eastern Mediterranean, SEM). There were less females than males in the progeny, both in the global dataset (32.5%) and within each group of parental origin (from 25.1% for NEM to 39.0% for WEM), with significant variation among populations dams and sires. Sex, body weight (BW) and body length (BL) showed moderate heritability (0.52 ± 0.17, 0.46 ± 0.17, 0.34 ± 0.15, respectively). Sex was genetically correlated with BW and BL (rAsex/BW = 0.69 ± 0.12, rAsex/BL = 0.66 ± 0.13). The weighted genome-wide association study (wGWAS) performed both on the global dataset and within each parental origin, revealed a different genetic architecture of sex determination between Atlantic and Mediterranean populations, with a gradient of similarities from Western to Eastern Mediterranean populations, consistent with the hypothesis of a population-specific evolution of polygenic sex determination systems in different environments.

Biological Data for the brilliant pomfret (Eumegistus illustris) off the coast of Reunion Island (SW Indian Ocean) between March 2014 and March 2015

[Lien vers la fiche source] The data come from the European project “ANCRE-DMX2” (Indicateurs biologiques et écologiques pour une gestion durable des stocks de poissons DéMersauX profonds d’intérêt halieutique à La Réunion). The brilliant pomfret (Eumegistus illustris) occurs in the western part of the Indian Ocean and the western and central Pacific Ocean. A total of 148 E. illustris were sampled in the landings of the French local artisanal fisheries (deep-water handline on electric reel), in the eastern part of Reunion Island (21°.10 S latitude; 55°.30 E longitude). Monthly samples were collected between March 2014 and March 2015. All fresh specimens were examined in the laboratory for Total Length (TL, mm), Standard Length (SL, mm), Fork length (FL, mm) Total wet weight (W, g) and sex. Since growth of E. illustris has not been investigated before, calibration of the method for age and growth structure determination was needed. Different calcified structures (otolith, scale, opercular bone, vertebra…) can be used for the age determination of fishes. For each fish, the sagittal otoliths, a few scales and opercular bones were used in order to estimate and compare the age of fish between three calcified structures. Morphological parameters of otoliths (length, width, area and weight) were extracted by the TNPC software (http://www.tnpc.fr/fr/tnpc.html). Different parts of opercular (opercular and sub_opercular bones) were sampled from left and right head sides. Depending of fish size, opercular were boiled during 5 to 15 minutes to clean any excess of flesh. The age data were estimated from only opercular bones.
Biometric data for large pelagic fish in the Indian Ocean

[Lien vers la fiche source] Biometric relationships are critical to convert measurement performed at landings (fish with head, tail cut or gutted and gilled) to standardized measurements which can be used in stock assessment and scientific purposes. In the Indian Ocean, while tuna species are relatively well described, there is a critical lack of information for billfish and the interannual and seasonal variations of these relationships are rarely investigated. To cope with this issue, the relationships used at IOTC are coming from other oceans or close species which is not scientifically satisfactory. In this document, we present the biometric relationships for 6 large pelagic species over 267 individuals in 2017 and 2018 from catches of Reunionese longliners. The classical length and weights are established for this species. While the relationships are very neat, further collections are needed to provide robust relationship. This document question our ability to share and build a global biological database at IOTC which can be regularly updated and provided the best scientific knowledge for these relationship. These data could be also used for other scientific needs and could be easily freely accessible as they are not sensitive.
Early diagenesis in the hypoxic zone of the Northern Gulf of Mexico : a disconnection between water column and sediment organic matter reactivity ?

[Lien vers la fiche source] Hypoxia and associated acidification is a growing concern for ecosystems and biogeochemical cycles in the coastal zone. The northern Gulf of Mexico (nGoM) has been experiencing large seasonal hypoxia for decades linked to the eutrophication of the continental shelf by the Mississippi River nutrient discharge. Sediments play a key role in maintaining hypoxic and acidified bottom waters, but the precise understanding of their role is still progressing. During the summer 2017 which hit a record in hypoxic surface area in the nGoM, we investigated 4 sediment stations located on the continental shelf under the influence of the Mississippi-Atchafalaya River System which are differentially influenced by the river input and seasonal hypoxia. Using a coupling between amperometric, potentiometric and voltammetric microprofiling with high-resolution Diffusion Equilibration in Thin-films (DET) profiles, and porewater analysis, we investigated the diagenetic processes in sediments under normoxic, hypoxic and nearly anoxic bottom waters. In addition, we used a time-series of bottom-water dissolved oxygen from May to November 2017 which indicated intense O2 consumption in bottom waters related to organic carbon recycling. At the sediment-water interface, we found that oxygen consumption linked to organic matter recycling was large with diffusive oxygen uptake (DOU) of 8 and 14 mmol m-2 y-1, except when oxygen concentration is near anoxia (5 mmol m-2 y-1). Deeper in the sediment, except at the station located near the river outlet, downcore sulfate decrease in pore waters was limited, with little increase of alkalinity, dissolved inorganic carbon (DIC), ammonium and phosphate suggesting that low oxygen conditions did not favor anoxic diagenesis as could be anticipated. We attributed the low intensity of anoxic diagenesis to a limitation in organic substrate supply possibly linked to the reduction of bioturbation during the hypoxic springs and summer.

P-wave velocity modelling on the West Sardinia margin

[Lien vers la fiche source] During the SARDINIA experiment, CHIRP profiles, bathymetry data, three coincident MCS reflection and wide-angle seismic profiles, and one single MCS reflection profile were collected on the West Sardinia margin. The MCS reflection data was acquired using a 4.5 km 360-trace digital streamer and a tuned airgun array of 8260 cubic inches, which was towed at a depth of 18-28 m. A total of 48 ocean bottom seismometers/hydrophones (OBS/OBH) from Ifremer, University of Brest, and Geomar Kiel were deployed on the West Sardinia margin, spaced every 7 nmi (~13 km). In five locations, three OBS were deployed at the same place to ensure the collection of data. The airgun array consists of 16 airguns ranging from 100 cubic inch G-guns to 16 L Bolt airguns, with main frequencies centered around 10-15 Hz. The airguns were tuned to the first bubble, to enhance low frequencies and ensure deep penetration. The shot interval was 60 s at an average speed of 5 knots, which translates to a trace spacing of about 140-150 m. The sample rate was 8 ms for the micrOBS, 5 ms for the Geomar, and 4 ms for the OldOBS. A total of 3573 shots (profile GH: 1130, profile G2H2: 1214) were fired by the air gun array. Profiles GH and G2H2, which are 160 and 200 km long transects, respectively cross the West Sardinia margin from the continental shelf to the “atypical” oceanic crust. Twenty-one ocean bottom seismometers (OBS) were deployed on the G2H2 profile, whereas sixteen were deployed on the GH profile. Additionally, the shots on this profile were recorded by eight land seismic stations (OSIRIS stations from the University of Brest and Geosciences Azur) that extended the marine profile ~150 km onshore. For the two profiles only 33 instruments were used in the wide-angle modeling, since four instruments (OBSS06, 18a, 30a, and 30c) did not record properly. We propose here the velocity models (v.in files) of the 2 main profiles located on the West sardinian margin, Profile K7L2, located on the shelf and parallel to the margin, is not presented since most of the deep arrivals are masked by the presence of sea-bottom multiples, preventing an accurate wide-angle model.

Eléments topographiques liés aux axes de ruissellement (cuvettes et remblais) sur Rennes Métropole

Cette couche vient en complément à la couche des axes de ruissellement sur Rennes Métropole (UUID = e0fa5c09-ee44-46ff-a068-b6dada575c9f) par analyse topographique. Dans le cadre de l'étude de ruissellement actuellement menée par Rennes Métropole (2023-2025) une première analyse du fonctionnement hydraulique du territoire a été réalisée à l’échelle globale de son territoire. Sur la base des formes du terrain naturel, l'analyse a permis d'identifier les éléments topographiques liés aux axes de ruissellement suivants : => Les zones de cuvettes en point bas/sans exutoires où les eaux auront tendance à s’accumuler naturellement ; Seules les cuvettes (ou dépressions topographiques) d’une profondeur inférieure à 10 m, d’une surface supérieure à 250 m², d’une profondeur supérieure à 20 cm sont affichées. Ces seuils d’affichage reposent sur des critères physiques : ils correspondent à la surface moyenne d’une parcelle en secteur urbanisé et à la hauteur d’une marche ou d’un trottoir. Les cuvettes affichées sont uniquement des cuvettes qui croisent un axe de ruissellement, elles ont donc un fonctionnement dynamique avec potentiellement des vitesses d’écoulement importantes. => Les remblais structurels, notamment d’infrastructures routières et voies ferrés, qui constituent des obstacles à l’écoulement naturel des eaux et qui peuvent donc générer des zones d’accumulation artificielles. Limites de l'utilisation de la donnée : Les éléments topographiques (cuvettes et remblais) cartographiés sont uniquement ceux qui croisent (dans un certain rayon) un axe de ruissellement. La totalité du volume d’une cuvette n’est pas nécessairement mobilisé en l'état actuel d'aménagement, mais il s’agit de zones qui pourraient être inondées en priorité en cas d'artificialisation des sols à proximité. Ainsi, il est dans tous les cas indispensables de confronter ces analyses à la réalité du territoire et notamment aux observations historiques recensées. Cela constitue plutôt une invitation à approfondir la connaissance des risques sur les secteurs à enjeux.
