title: Willingness to pay to conserve Mediterranean marine fauna (Actinopterygii, Chondrichthyes, Mammalia, Reptilia) in France

description: The willingness to pay (WTP) of people to protect animal populations can be used as a tool for these populations’ conservation. The WTP reflects the non-use value of animals, which can be significant for charismatic species. This value can be used as an economic criterion for decision-makers in order to recommend protective measures. The definition of the WTP to protect a species is challenging, as valuation methods are time-consuming and expensive. To overcome these limitations, we built a benefit transfer function based on 112 valuation studies and apply it to 440 Mediterranean marine species. We extracted these species from the IUCN database and retrieved some required parameters from, amongst others, the FishBase database. Marine mammals appear to have the highest WTP value followed in order by sea turtles, sharks and rays, and ray-finned fishes. Commercial fish species appear to have the highest values amongst the fish class.

title: Tsunamis generated by subaerial landslides: From laboratory experiments to geophysical events

description: Modeling of tsunami waves generated by subaerial landslides is important to provide accurate hazard and risk assessments in coastal areas. We perform small-scale laboratory experiments where a tsunami-like wave is generated by the collapse of a subaerial granular column into water. The maximal amplitude of the leading wave is shown to scale linearly with the instantaneous immersed volume of grains and sublinearly with the final immersed deposit. From available measurements of the immersed deposits of past geophysical events, the maximal amplitude of the generated wave predicted by our empirical law is in good agreement with previous numerical or experimental modelings based on the inland geometry of the slide. Our results suggest that o shore deposits of past landslides can be used to constrain the amplitude of paleo-tsunamis.

title: Antarctic bivalve Limatula hodgsoni as a proxy for ambient oceanographic conditions at McMurdo Sound

description: Bivalves have been used as proxies to reconstruct ancient oceanographic conditions based on the assumption that their shell calcite is precipitated in near isotopic equilibrium with ambient seawater. Few studies, however, have tested the presumption of equilibrium precipitation for specimens from polar environments. Furthermore, reported isotopic values for polar specimens are largely indicative of disequilibrium precipitation, leading to the conclusion that bivalves living in extreme environments may be poor recorders of ambient oceanography. An analysis of shell chemistry of the Antarctic bivalve Limatula hodgsoni is compared to the local oceanographic data at Cape Armitage, McMurdo Sound, to assess the suitability of extreme environment bivalves as environmental proxies. Results reveal that significant kinetic fractionation occurs during primary-layer shell secretion, resulting in whole-shell isotopic compositions that do not reflect equilibrium with ambient seawater. Secondary-layer shell calcite, however, is less affected by biological fractionation and exhibits isotopic compositions that fall within the range of predicted equilibrium values. Additionally, whole-shell concentrations of elements including Ba, Cd, Cr, Fe, Mn, Na, Sr, and Zn exhibit trends that are interpreted to reflect their relative concentrations in ambient seawater. Concentrations of Mg and B, however, are found to be largely controlled by physiological processes related to bivalve growth rate. While this study concludes that the shell chemistry of L. hodgsoni does reflect the local oceanographic conditions, the reliability of extreme-environment bivalves should be assessed on a species basis as differences in bivalve physiology and microstructure can significantly influence the degree of equilibrium reflected in shell calcite.

title: CTD profile and MMS data from P-MoVE cruise

description: Aimed at understanding the mesoscale eddy’s effect on the subduction and dissipation of the North Pacific Subtropical Mode Water, a field experiment namely the Pacific Mode Water Ventilation Experiment (P-MoVE) was carried out in the northwestern Pacific Ocean (Xie et al., 2013; Xu et al., 2016). During 27 March to 5 April 2014, we conducted 54 station surveys in an anticyclonic eddy (AE) and a nearby weak cyclonic eddy (CE) with a spacing of 0.25° (Figure 1). The conductivity-temperature-depth system (CTD 911plus, Sea-Bird Electronics) and microstructure probe (MSS-90, Sea & Sun Technology) were deployed to obtain temperature-salinity profiles and microscale velocity shear at these stations.

title: Complementarity and discriminatory power of genotype and otolith shape in describing the fine-scale population structure of an exploited fish, the common sole of the Eastern English Channel

description: Marine organisms show population structure at a relatively fine spatial scale, even in open habitats. The tools commonly used to assess subtle patterns of connectivity have diverse levels of resolution. We have assessed the discriminatory power of genetic markers and otolith shape to reveal the population structure of the common sole (Solea solea), living in the Eastern English Channel stock off France and the UK. The aims were to (i) inform the short and long-term population structure by comparing genetic and otolith shape approaches, and (ii) combine the tracers in a single analysis to assess the interest of a combined approach. First, we applied Single Nucleotide Polymorphisms to assess population structure at an evolutionary scale. Then, we tested for spatial segregation of the subpopulations using otolith shape as an integrative tracer of life history. Finally, we combined the genotypes and otolith phenotypes in a supervised machine learning framework to probabilistically assign adults to subpopulations. Genetic assignments and otolith shape analyses provided congruent results suggestive of a metapopulation structure for the common sole of the Eastern English Channel. Despite congruent results from genetics and otolith shape, the combined analysis did not provide realistic reallocation probabilities. Our findings support the idea that independent analyses of tracers provide fruitful insights and that a combined approach should be preferred when a large and balanced number of fish is available for each tracer analyzed.

title: Species richness, abundance and biomass data for assessing fish spillover from Mediterranean Marine Protected Areas

description: This dataset gathers total species richness, total abundance and total biomass of fishes recorded in six Mediterranean Marine Protected Areas in summer by underwater visual censuses performed on rocky areas at varying distances from the core of the MPA. Belt transects (25 x 5 m) were run parallel to the coast between 6 and 12 m depth, except in Tabarca Posidonia beds (50 x 5 m). Additionally, reduced fish species richness, abundance and biomass excluding zooplanktivorous fish species (Atherinidae, Clupeidae, Centracanthidae, Engraulidae, Pomacentridae, and the Sparidae Boops boops) were given as their fluctuating abundance and aggregative behavior may mask the effect of protection.

title: 30–50 h band-pass filtered mooring data near the Shelf Break of the Chukchi Sea

description: Topographic Rossby waves (TRWs) were observed with a period of approximately 35 h using a mooring observation on the shelf break of the Chukchi Sea in the Arctic Ocean. One mooring (CP14) was deployed at 74.80°N and 167.89°W during the Araon Cruise (ARA05B) by Korea Polar Research Institute (KOPRI). The mooring was equipped with an upward looking acoustic Doppler current profiler (ADCP, Workhorse sentinel [WHS] 600 kHz) at approximately 58 m, a downward looking ADCP (WHS 300 kHz) at approximately 63 m, 29 temperature sensors (Sea Bird Electronics [SBE] 56 and SBE 37-SM), and four salinity sensors (SBE 37-SM). Data were collected for approximately one year from 21 August 2014 to 5 August 2015. Observed TRW events coincided with local sea ice concentration (MASAM2: Daily 4-km Arctic Sea Ice Concentration) and wind-stress (ERA-Interim daily reanalysis dataset) events.

title: Early diagenesis in the hypoxic zone of the Northern Gulf of Mexico : a disconnection between water column and sediment organic matter reactivity ?

description: 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.

title: The diversity of shallow habitats in New Caledonia reefs and lagoons

description: This document forms an appendix to the paper "A regionally scalable habitat typology for assessing benthic habitats and fish communities: application to New Caledonia reefs and lagoons" published in 2020 in the journal Ecology and Evolution by Dominique Pelletier, Nazha Selmaoui-Folcher, Thomas Bockel and Thomas Schohn. The paper describes a new methodology for i) determining habitat types consistent across scales within large management units, ii) characterizing heterogeneities within each habitat, and iii) predicting habitat from new survey data. It relies on clustering techniques and supervised classification rules and was applied to a set of 3145 underwater video observations of fish and benthic habitats collected in all reef and lagoon habitats around New Caledonia. A baseline habitat typology was established with five habitat types clearly characterized by abiotic and biotic attributes. In a complex mosaic of habitats, habitat type is an indispensable covariate for explaining spatial variations in fish communities. Habitat types were further described by 26 rules capturing the range of habitat features encountered. Rules provided intuitive habitat descriptions and predicted habitat type for new monitoring observations, both straightforwardly and with known confidence. Images are convenient for interacting with managers and stakeholders. This documents contains sample images illustrating each of the rules obtained and depicts the diversity of shallow seascapes encountered in the Coral Sea Marine Park and in the coastal areas of New Caledonia.

title: CTD Castaway shallow water cast Mexican North Caribbean/ CAISTER VERANO 2019

description: This work consisted of making CTD measurements on the coasts of Isla Mujeres, as well as in the lagoons called "las salinas". The main objective was to have records of temperature and salinity of the Isla Mujeres water bodies . So measurements were made with a Castaway Sontek CTD with a total of 68 measurements. The names of these lagoons "Las salinas" are; Laguna Makax and Salina Chica. The information was analyzed statistically and maps were made in geographic information systems QGIS. The results were that “Las salinas” found salinity levels between 4.6 PSU and 12 PSU. The Makax lagoon is the body of water that registered higher salinity values ​​(38.23 PSU on average) due to its proximity to the sea. The salinity of the sea that surrounds Isla Mujeres is 35.48 PSU on average.

title: Tunabio: biological traits of tropical tuna and bycatch species caught by purse seine fisheries in the Western Indian and Eastern Central Atlantic Oceans

description: Along with the development of the tropical tuna purse seine fishery from the 1960s in the Atlantic Ocean and from the 1980s in the Indian Ocean, many projects and studies have been conducted to improve knowledge about the biology, migrations, and dynamics of the stocks of target and non-target (i.e., bycatch) species taken in these fisheries. Since the 2000s, the European Union (EU) has been supporting Member States in the collection of biological data on species caught by their purse seine and pole and line fisheries, thus making it possible to have long-time series of data. These data are essential to monitor the status of the fisheries and fuel the assessment models used by the tuna Regional Fisheries Management Organisations (tRFMOs) for the sustainable management and conservation of the fish stocks under their mandate. We combined historical (1974-1999) and current (2003-2020) data sets on the biology of tropical tunas and bycatch fish caught by large-scale purse seiners in the Eastern Atlantic Ocean (EAO) and Western Indian Ocean (WIO). The resulting Tunabio database contains all available morphometric and biological data collected on more than 80,000 fish individuals.

title: Measurements in the wake of an undulating membrane tidal energy converter

description: The tidal energy converter studied here is based on the fluid-structure interactions that occur between a flexible membrane and an axial flow, resulting in an undulating motion that can be used to harvest energy. Its wake is experimentally characterized from two-dimensional Particle Image Velocimetry (PIV) measurements. PIV is synchronized with a motion tracking system that gives information on trajectory and power conversion. Wake measurement gives access to velocity deficit, turbulence intensity and vorticity. Three configurations are tested in order to identify the influence of the main adjustment parameters.

title: Haliotis tuberculata , a generalist marine herbivore that prefers a mixed diet, but with consistent individual foraging activity

description: While population foraging behaviour of herbivores has been extensively studied, individual choice is still poorly understood. Because marine ectotherms are strongly influenced by their environment and because a mixed diet is appropriate for herbivores, we hypothesized that Haliotis tuberculata, a large marine gastropod, would not exhibit significant individual consistency in foraging activity and would display generalist food choices. To test these hypotheses, the behaviour of 120 abalone was studied using a choice test of eight macroalgal species (Asparagopsis armata, Palmaria palmata, Enteromorpha intestinalis, Ulva lactuca, Saccharina latissima, Saccorhyza polyschides, Laminaria digitata and stipes of Laminaria hyperborea). Adult Haliotis tuberculata, reared during 4 years in sea-cage structure were transported to a land-based laboratory. Once in the laboratory, eight abalone were randomly assigned to each experimental tank (n= 15 tanks in total). A reflective tag was glued to each individual to allow us to recognize each individual abalone. Foraging activity and food choice was determined for each individual over 3-weeks, with video recording 24 hours a day.
