title: Amazon river plume Hydro-thermodynamic Dataset (ArpHD)

description: This dataset contains the results of the paper published in Tropical Oceanography titled "Influence of underwater hydrodynamics on oil and gas blowouts off Amazon River mouth" and the paper published in Dynamics of Atmospheres and Oceans with the title "Amazon River plume influence on Western Tropical Atlantic dynamic variability", in addition this dataset was also used in the paper titled" Amazon river plume influence on planktonic decapods in the tropical Atlantic" which is published in the Journal of Marine Systems. This dataset was obtained through a simulation using the ROMS model (Regional Ocean Model System) and was adjusted to reproduce the best possible hydro-thermodynamics in the area of the mouth of the Amazon and Para rivers, as well as in the area of the retroflexion of the North Brazil Current (NBC), showing how the low salinity waters of the Amazon and Para rivers are transported in the different months and weeks of the year. This dataset is located in an area belonging to Western Tropical North Atlantic (WTNA), geographically framed at 60.5°–24°W and 5°S–16°N. The simulation was performed with 0.25° horizontal resolution and 32 vertical levels. As the Amazon River has a well-branched delta that is defined by 4 channels, the total monthly mean discharge was divided among the 4 mouths according to their dimensions, that is, into 4 virtual rivers; The river Para does not have a delta, so it was considered as it is in reality. The temperature, salinity and marine currents distributions obtained numerically were compared with SODA (Simple Ocean Data Assimilation), with the in situ observations of the PIRATA project buoys (Prediction Research Moored Array in the Tropical Atlantic) located at (38°W, 8°N) and at (38°W, 12°N) and with the surface currents of SCUD model (Surface Currents from Diagnostic model), in all cases small differences were obtained between the numerical variables and those of the SODA, PIRATA and SCUD datasets, obtaining an optimal hydro-thermodynamic model of that area.

title: Indian Marine Fish Life Histories (INMARLH) database for determining resilience and vulnerability of tropical marine species

description: Taking advantage of published data on life-history traits and short-term information on fishery parameters from 3132 records for 644 fish stocks along the coast of India, we calculated resilience (R) and vulnerability (V). Further, we developed an Index of Resilience and Vulnerability (IRV) for 133 species of tropical finfishes, crustaceans, and molluscs. Using 7 resilience and 6 vulnerability attributes, two-dimensional scatter plots of the resilience and vulnerability scores were generated and the Euclidean distance and angle from the origin to each point were calculated to determine IRV and the effect of fishing on fish species. By ranking the species, the top 10 highly resilient, highly vulnerable, and high-risk species (low IRV) were identified. While small-sized species with fast growth rate and low trophic level were among the highly resilient species, large predatory species such as sharks and barracudas were among the highly vulnerable and high-risk species. More than 100 of the 133 species were resilient-yet-vulnerable, and most crustaceans showed high resilience. Differences in IRV scores among species within the same family were discernible, indicating the differences in the biological characteristics and response to fishing. Sensitivity analysis indicated that an abridged IRV with 6 attributes works similar to 13 attributes and can be used in data-deficient situations. Comparison of R and V of IRV with other assessments showed different results because of divergences in the objectives, number and types of attributes, and thresholds used. These assessments do not convey the same information and therefore great care must be taken for reproducing these frameworks to other fisheries. The results of IRV analysis can be useful for stock assessments and in developing effective management measures in combination with other complementary information.

title: TERIFIC Ocean Glider Deployments in the Labrador Sea

description: As part of the TERIFIC (Targeted Experiment to Reconcile Increased Freshwater with Increased Convection) project funded by the European Research Council, two Kongsberg Seagliders (sg602 and sg638) were deployed offshore of Qaqortoq, southwest of Greenland, in December 2019 from the 30-m research vessel Adolf Jensen. Both gliders were retrieved in Trinity Bay on the Labrador coast of Canada in May 2020 from a fishing boat. Glider sg602 had a standard fairing and a standard hardware; glider sg638 had an ogive fairing and was equipped with a science controller. Unpumped CTDs (Conductivity, Temperature, and Depth), referred to as CT sails and provided by Sea-Bird Electronics (Bellevue, WA) were mounted on both Seagliders with a sampling frequency of 0.1 Hz. An Aanderaa oxygen optode was also fixed on both gliders but only sg638 returned measurements of dissolved oxygen concentration. Both gliders were equipped with WETLabs (Western Environmental Technologies Laboratories) BBFL2 ECO Puck that measures chlorophyll, colored dissolved organic matter and optical backscatter (700 nm). Initial processing with the University of Washington’s basestation corrects for the thermal-inertia effect of the CT sail. Both gliders were processed with the GliderTools toolbox (Gregor et al., 2019) to determine adjusted temperature and salinity variables.

title: Simulated NPP considering changes in atmospheric CO2, of the physical climate, and of land-derived nutrient inputs in a global ocean biogeochemistry model

description: We performed a series of global ocean biogeochemistry model simulations over 1905 to 2010 taking into account 1. changes in atmospheric CO2, 2. changes in atmospheric CO2 and changes in the physical climate, and 3. hanges in atmospheric CO2,changes in the physical climate, as well as changes in land-derived inputs of P and N, including both riverine & atmospheric deposition perturbations. These simulations can be used to isolate for the individual effects on the marine carbon cycle arising from pertubations of atmospheric CO2, of the physical climate, and of land-derived nutrient inputs. The simulations were performed in the Max-Planck-Institute Ocean Model (MPI-OM) TP04 configuration, which resolves the global ocean at a resolution of around 0.4 degrees, coupled an enhanced version of the ocean biogeochemistry model HAMOCC for a better representation of processes taking place in the coastal ocean.

title: Biofloc technology: An environmental management approach in carp (Cyprinus carpio ver. communis) culture

description: Supplementation of biofloc in common carp (Cyprinus carpio ver. Communis (0.84±0.003g) culture was investigated in replacing commercial feed. Two studies were conducted for 120 days in outdoor experimental cisterns with reduction of feed from 50% to 100%, with two biofloc media; without (Experiment 1; E1) and with neem extract (Experiment 2; E2). The experimental groups were: biofloc with feeding at 6% body weight (T1E1 and T1E2), biofloc with feeding at 3% body weight (T2E1 and T2E2), biofloc without feeding (T3E1 and T3E2), feeding at 6% body weight (C1) and only biofloc (C2E1 and C2E2). %%%. Absolute weight gain in T2E1 was 8.97 times and in T2E2 was 4.63 times higher than C1. In spite of 18.54% and 7.26% higher growth respectively in T1E1 and T1E2 than C1, BFT could not compensate the total withdrawal of feed (T3E1 and T3E2) and resulted in 22.22% to 33.33% mortality in T3E2 and T3E1, respectively. Under identical feeding regime, FCR was improved by 52.57% to53.76 % in T2E1 and 48.71% to 51.23% in T2E2 compared to T1E1 and T1E2 respectively. Increased N: P ratio of water and soil in E2 favoured fish growth. Neem leave extract in biofloc media should be judicious as it may cause nitrification inhibition.

title: Microscopy of larval stages of the honeycomb worm Sabellaria alveolata from five European populations, under different temperature treatments

description: Phenotypic plasticity, the ability of a single genotype to produce multiple phenotypes, is important for survival when species are faced with novel conditions. Theory predicts that range-edge populations will have greater phenotypic plasticity than core populations, but empirical examples from the wild are rare. The honeycomb worm, Sabellaria alveolata (L.), constructs the largest biogenic reefs in Europe, which support high biodiversity and numerous ecological functions. In order to assess the presence, causes and consequences of intraspecific variation in developmental plasticity and thermal adaptation in the honeycomb worm, we carried out common-garden experiments using the larvae of individuals sampled from along a latitudinal gradient covering the entire range of the species. We exposed larvae to three temperature treatments and measured phenotypic traits throughout development. We found phenotypic plasticity in larval growth rate but local adaptation in terms of larval period. The northern and southern range-edge populations of S. alveolata showed phenotypic plasticity for growth rate: growth rate increased as temperature treatment increased. In contrast, the core range populations showed no evidence of phenotypic plasticity. We present a rare case of range-edge plasticity at both the northern and southern range limit of species, likely caused by evolution of phenotypic plasticity during range expansion and its maintenance in highly heterogeneous environments. This dataset presents the raw image data collected for larval stages of Sabellaria alveolata from 5 populations across Europe and Northern Africa, exposed to 15, 20 and 25 C. Included are also opercular crown measurements used to estimate de size classes of individuals present in each population. All measurements made with the images collected are presented in an Excel spreadsheet, also available here.

title: Force variations measurement on a tidal turbine model due to tower proximity

description: The main objective of these tests is to quantify the effects of the tower proximity on the force variations of a horizontal axis tidal turbine. The experimental tests have been carried out in the wave and current flume tank of Ifremer at Boulogne-sur-mer, France. Four distances between a dummy tower and the turbine rotor have been tested. For every position of the dummy tower, three flow velocities and eleven turbine rotation speeds have been selected. The turbine performance has been quantified without the dummy tower as well, to generate a reference set of plots for all flow velocities and turbine rotation speeds. The turbine performance is quantified through the rotor torque, thrust and blade root forces and moments. An inflow velocity measurement has been systematically recorded in synchronization with the turbine parameters, for every acquisition, using a 3 components Laser Doppler Velocimeter.

title: Controls on the distributions of dissolved Cd, Cu, Zn, and Cu-binding organic ligands in the East China Sea

description: The East China Sea (ECS) is a complex marginal sea with potential sources and sinks of trace metals. In this study, we investigated the distributions of dissolved Cd, Cu, Zn, and Cu-binding organic ligands in the ECS. Concentrations of Cd and macronutrients were below detection limit in the surface Kuroshio waters. Surface Zn concentrations increased along the Kuroshio Current, which may be attributed to atmospheric deposition. We detected two classes of Cu-binding organic ligands in those waters, classified as L1 (log K = 13.6-15.2) and L2 (log K = 11.2-13.1), respectively. L1 could be related to biological production while L2 distributions appeared to be controlled by water mass mixing. Particularly, the Kuroshio Surface Water had relatively low L2 concentrations. There were no significant sources of Cu-binding organic ligands in the intermediate waters. Cd, Cu, and Zn exhibited strong positive relationships with phosphate in the intermediate waters, suggesting that phytoplankton uptake and subsequent regeneration were the dominant controls of these elements at these depths. In deep waters, the distributions of Cd, Cu, and Zn were mainly controlled by water mass mixing. This was apparent from the unique trace metal to macronutrient ratios propagating from the South China Sea and West Philippine Sea to the ECS, according to water mass mixing patterns. Cd/phosphate, Zn/phosphate, Zn/silicate, and Cu/silicate ratios in the ECS were comparable with those in the North Pacific region. This implies the absence of additional supplies of Cd, Cu, Zn, and macronutrients from marginal sources in the ECS.

title: Biological traits of macroinvertebrates associated with subtidal sandy beforms

description: Subtidal sandy bedforms are under the particular protection of the NATURA 2000 directive because they constitute important habitats where 30% of the species are endemic. The ecosystems they support as well as their dynamic are however little investigated. Taking into account that bedforms areas are currently targeted for the commissioning of offshore wind farms and that a substantial need of knowledge will be required to implement environmental impact assessments, the present study aims to describe how the benthic ecosystem functioning vary in relation with (i) the type of bedform, (ii) the season as well as (iii) within bedforms (from the troughs to the crests). We present here the biological traits database used to address these issues. Macrobenthic organisms were collected on an 80 km2 area typified by various kind of bedforms and located offshore the Dunkirk harbor. Sampling were performed in the autumn of 2019 (October) and the spring of 2020 (May) at 23 stations distributed according to a stratified sampling design. A total of 9 traits were selected in order to reflect (i) the response of benthic organisms to the physical disturbance induced by sand dunes migrations and (ii) the dynamics of macrobenthic communities in sublittoral sediments. Traits were the mobility, fragility, position on substrata, average size, feeding mode, longevity, egg development, larval development and life stage. Traits were split in 31 modalities and a score was attributed to each species in order to reflect their affinity to each modality (fuzzy-coding principle; Chevene et al., 1994). A score of 0 means no affinity whereas a score of 3 stands for full affinity of a species to a given modality. Scores were attributed from data available on the online BIOTIC database (MarLIN, 2006) and completed thanks to published (Foveau et al., 2020) or unpublished databases (Garcia unpublished data; Sturbois et al., unpublished data; Rigolet et al., unpublished data). In case of missing data for certain species, scores of the higher taxonomic level (mostly genus level) were attributed. For the trait "life stage", the score corresponded to the ratio between the abundance of juvenile and the abundance of adult in the community. The present dataset includes 107 taxa.
