title: Tropicalization of the barrier islands of the northern Gulf of Mexico: A comparison of herbivory and decomposition rates between smooth cordgrass (Spartina alterniflora) and black mangrove (Avicennia germinans)

description: The expansion of black mangrove Avicennia germinans into historically smooth cordgrass Spartina alterniflora-dominated marshes with warming temperatures heralds the migration of the marsh-mangrove ecotone northward in the northern Gulf of Mexico. With this shift, Avicennia is expected to outcompete Spartina where it is able to establish, offering another prevalent food source to first order consumers. In this study, we find Avicennia leaves to be more preferable to chewing herbivores, but simultaneously, chewing herbivores cause more damage to Spartina leaves. Despite higher nitrogen content, Avicennia leaves decomposed slower than Spartina leaves, perhaps due to other leaf constituents or a different microbial community, for other studies have found the opposite in decomposition rates of the two species’ leaf tissue. This study provides insights into basic trophic process, herbivory and decomposition, at the initial stages of black mangrove colonization into Spartina salt marsh.

title: Data related to biogenic dissolution rates quantified in various carbonate substrates exposed to ocean acidification at Ischia (Italy) and Faial (Azores)

description: Recent studies carried out in coral reef settings or under controlled conditions showed that rising aqueous pCO2 (pH ≥ 7.8 – 7.9, and a saturation state of carbonate minerals &gt; 1) stimulates the growth of reef microboring or euendolithic phototrophs, especially microalgae, and therefore, enhance rates of biogenic dissolution of carbonates. Those micro-organisms play a major role in reef bioerosion and coral reef functioning. In temperate-cold carbonate ecosystems, carbonate dissolution by euendolithic microflora has never been investigated under natural ocean acidification conditions. We thus realized two experiments to investigate the effects of low pH (and saturation states) on early natural microboring communities colonizing various carbonates and their associated rates of biogenic dissolution. One was carried out at Ischia (Italy) with mollusk shells exposed at two CO2 vents (pH &lt; 7.5) vs an ambient site (pH ~ 8) during six months. The other one was realized at Faial (Azores) with various carbonate substrates (both aragonite and calcite) at one CO2 vent (pH ~ 7.4) vs an ambient site (pH ~ 8) over 45 days. Here we provide the data which allowed calculating rates of carbonate biogenic dissolution at all studied sites; i.e. the depth of penetration of euendolithic filaments into carbonates and the % of surface area of substrate colonized by microborers (bioeroded surface area). Rates of biogenic dissolution per site and per location are also provided, as well as environmental data collected at Faial (those collected at Ischia are published elsewhere). A total of 5 excel files is thus provided.

title: ADCP mooring data in 2007-2008 north of Svalbard over the Yermak Plateau in the Yermak Pass

description: The mooring was deployed on 25 July 2007 from the R/V Haakon Mosby at 80.601°N, 7.119°E (depth of 745 m) in the Yermak Pass over the Yermak Plateau north of Svalbard. It comprised an upward-looking RDI 75kHz Long Ranger Acoustic Doppler Current Profiler (ADCP) at 585 m with 16 m vertical resolution and a 1hour sampling time, and an ocean profiler on a taut cable between 130 and 530 m. The mooring was recovered on 23 September 2008 by the K/V Svalbard. The dataset is composed of the raw data from the ADCP, after declination correction. A white shaded zone is visible in the data between 380 and 500 m depth throughout the time series. It corresponds to the reflection of the acoustic bins on the profiler stuck on the cable.

title: Collocations of ICOADS and Ocean Heat Flux (centered five-day) daily sensible and latent heat flux estimates

description: Ocean latent (LHF) and sensible (SHF) heat flux products developed by several scientific groups have been examined in the European Space Agency (ESA) Ocean Heat Flux (OHF) project. This dataset is the collocations of nine OHF products with in situ surface marine observations of the International Comprehensive Ocean–Atmosphere Data Set (ICOADS Version 3). Required for inclusion are that a) valid collocations exist with all OHF products and their ensemble and b) all ICOADS variables required to calculate a COARE flux estimate are within 2.8 estimated standard deviations of their respective smoothed monthly climatology. All values (including ICOADS flux estimates by the COARE 3.0 algorithm) are considered at the daily, 0.25-degree resolution of the project’s reference grid. The nine product collocations include additional samples at daily intervals from two days before to two days after ICOADS collocation. Further information about the nine standardized products can be found in Bentamy et al. (2018).

title: Collocations of surface drifter and GlobCurrent (centered five-day) 15-m zonal and meridional velocity estimates

description: GlobCurrent is an analysis that linearly combines the geostrophic and Ekman components. Drifters respond locally to a combination of geostrophic, Ekman, tidal, inertial, Stokes, and wind drift processes, including processes on scales smaller and faster than the GlobCurrent grid can resolve. Collocations of drifters (whose drogues move roughly with the 15-m current) and GlobCurrent (also at 15 m, with additional samples at daily intervals from two days before to two days after collocation) are included in this dataset. Six-hourly drifter velocity has been estimated following Hansen and Poulain (1996). We restrict attention to drifters whose continuous drogue presence was confirmed by objective or subjective means (Rio et al. 2012, Lumpkin et al. 2013). The resulting geographic distribution for 1993-2015 (Fig. 1) yields more than eleven million drifter and GlobCurrent zonal and meridional velocity estimates. (A comparable number of drifters lost their drogues and, being more responsive to surface wind forcing, are omitted.)

title: REMOULA temperature dataset survey 2000 - 2012. Blue mussel growth in the Pertuis Charentais sounds (Bay of Biscay)

description: Concomitantly to the monitoring network of the Blue mussel growth in the Pertuis Charentais sounds, (available soon from SEANOE) high frequency temperature measurements were carried out on a regular basis and on all REMOULA monitoring stations. Temperature were recorded every 15’ on 7 experimental sites from 2010 to 2012. Two environemental conditions were tested, i.e. off shore and intertidal areas. The off-shore sites are located along the long lines mussel growout facilities (Filières Pertuis Breton, Saumonards Filières). Intertidally, temperature sensors were deployed on bouchot type mussel culture (wooden piles) (Roulières, Aiguillon, Marsilly, Boyard-bouchot, Yves). Due to the tidal cycle, the later are emersed on a regular basis – during this period of time, air temperature is recorded. The data set are presented in two ways: raw data (immersion-emersion values) and daily average (only immersed data). The daily average aims to represent the lasting period of mussel activity for further comparison with off shore conditions. For off-shore sites, daily averaged data are presented. For intertidal areas (bouchot type), the average is based upon the two daily high tides. Daily data are recorded in betwwen 2 hours before and after the high tide peak. Figures are presented per campaign and per site. Data temperature are recorded using Tidbit V2 logger (-39°C+75°C) and Sensor EN Optic STOWAWAY TEMP (-39+75°C) ONSET COMPUTER from 2000 to 2009 and NKE STPS30 probes (with and without chlorine system) and YSI 6600 from 2010 to 2012. Data storage is organized using the Quadrige data bank system. Coastal monitoring information are saved in the Coastal monitoring Quadrige information system.

title: Regional monitoring network of the Blue mussel (Mytilus edulis) rearing performances in the Pertuis Charentais sounds (Bay of Biscay). REMOULA network 2000 - 2012

description: On a yearly basis, mussel farming produces around 13 000 metric tons of mussel in the Pertuis Charentais sounds (Pertuis Breton et Pertuis d’Antioche). This represents 23% of the Blue mussel (Mytilus edulis) production along the French Atlantic coastline. Production is characterized in this area by to types of growout systems: the ‘bouchot’ type culture using wooden poles(p) and off-shore longlines(l). Environmental conditions are mainly estuarine. Taking into account those cultural practices, the REMOULA monitoring network has been deployed since 2000 to provide baseline information to better understand the Blue mussel (Aiguillon(p) and Filières Pertuis Breton(l)) or trimester (Roulières(p), Marsilly(p), Yves(p), Boyard-bouchot(p) – completed by the stations Saumonards Filières(l) and Filières Chatellaillon 2(l) (2008 to 2012). Between 2000 and 2005 the mussel batches monitoring lasted 12 months whereas it lasted 15 months from 2006 to 2012. The initial batch of mussel is originating from the spat settlement the previous year and calibrated. On the 8 monitoring stations, calibrated mussel batches were deployed into bags (120 mussels/bag). Biometric data are measured during each monthly survey (30 individuals) and a mortality rate estimated. Additional information is obtained through biochemical analysis (proteins, lipids, carbohydrates) on 3 mussel pools of 10 individuals in 2000, 2001, 2002, 2003 and 2004. Moreover gametogenic data are collected on 15 mussels (2003 and 2004). The data storage is organized using the Quadrige2 system and characterized by individual field campaign. Coastal monitoring data Available parameters : Individual measurement : length, shell weight, dry meat weight. Width and height at the beginning and the campaign end. Average measurement : individual weight (3x10 individuals), Calculated data: Lawrence & Scott indicator, Walne and Mann indicator, meat indicator, mortality rate % Observations : Pinnotheres and Polydora infestations, parasites.

title: A global database of vertical profiles derived from Biogeochemical Argo float measurements for biogeochemical and bio-optical applications

description: The presented database includes 0-1000 m vertical profiles of bio-optical and biogeochemical variables acquired by autonomous profiling Biogeochemical-Argo (BGC-Argo) floats. Data have been collected between October 2012 and January 2016, around local noon, in several oceanic areas encompassing the diversity of ocean’s trophic environments. The database includes profiles of downward irradiance at 3 wavelengths (380, 412 and 490 nm), photosynthetically available radiation, chlorophyll a concentration, fluorescent dissolved organic matter, and particle light backscattering at 700 nm. All variables have been quality controlled following specifically-developed procedures, that aimed to support biogeochemical and bio-optical applications at the global scale. Data corruption by biofouling and any instrumental drift has also been verified. Moreover, to allow users for different biogeochemical applications, vertical profiles of chlorophyll a and particle light backscattering at 700 nm have been presented before and after advanced processing (e.g., non-photochemical quenching correction, identification of spikes). Vertical profiles of temperature and salinity associated to these bio-optical data are also provided although they have been only quality-controlled for sensor issues related to bio-fouling and instrumental drift.

title: Draft genomes of the algae Tisochrysis lutea strains

description: In a context of human population increase and depletion of terrestrial resources, exploitation of microalgae is an ecofriendly alternative path for the future. Currently, microalgae are used in many areas domain like food, feed, bio-remediation, health industry and third generation biofuels. Yet, until now, all cultivated microalgae strains are derived directly from their natural environment. One way of improving productivity is the acquisition of selected algae strains with improved capabilities. In this study, we show that the intra-strain diversity in microalgae can be exploited to produce improved strains. An improved strain with high neutral lipid productivity was obtained, which could be used, for example, for feed or bio-fuels applications. This study also shows the necessity to study and exploit biodiversity within microalgae specie. In addition, we obtained drafts genomes and phenotypic comparisons between the wild-type and the improved clonal strains. These results reflect the origin of intra-strain diversity and microalgae adaptive capacity. The clonal strain selected accumulates more lipids, at the expense of carbohydrates. The numerous patterns of transposable element activity suggest that it is the main driver of this adaptation.

title: A global bio-optical database derived from Biogeochemical Argo float measurements within the layer of interest for field and remote ocean color applications

description: The database here presented includes quality-controlled bio-optical and biogeochemical variables derived from autonomous profiling Biogeochemical Argo float measurements, and supports field and remote ocean color applications. Data represent the first optical depth (i.e., the layer of interest for satellite remote sensing) and have been collected between October 2012 and January 2016, around local noon, in several oceanic areas encompassing the diversity of ocean’s trophic environments. In addition to the first optical depth (as derived from the in situ measured depth of the euphotic layer), the presented database is compiled with data of diffuse light attenuation coefficients of photosynthetically available radiation and downward irradiance at 3 wavelengths (380, 412 and 490 nm), chlorophyll a concentration, fluorescent dissolved organic matter, and particle light backscattering at 700 nm. Associated errors to each variable are also reported.

title: Heritability of Boldness and Hypoxia Avoidance in European Seabass, Dicentrarchus labrax

description: To understand the genetic basis of coping style in European seabass, fish from a full factorial mating (10 females x 50 males) were reared in common garden and individually tagged. Individuals coping style was characterized through behavior tests at four different ages, categorizing fish into proactive or reactive: a hypoxia avoidance test (at 255 days post hatching, dph) and 3 risk-taking tests (at 276, 286 and 304 dph). We observed significant heritability of the coping style, higher for the average of risk-taking scores (h² = 0.45 ± 0.14) than for the hypoxia avoidance test (h² = 0.19 ± 0.10). The genetic correlations between the three risk-taking scores were very high (rA = 0.96 – 0.99) showing that although their repeatability was moderately high (rP = 0.64 – 0.72), successive risk-taking tests evaluated the same genetic variation. A mild genetic correlation between the results of the hypoxia avoidance test and the average of risk-taking scores (0.45 ± 0.27) suggested that hypoxia avoidance and risk-taking tests do not address exactly the same behavioral and physiological responses. Genetic correlations between weight and risk taking traits showed negative values whatever the test used in our population i.e. reactive individual weights were larger. The results of this quantitative genetic analysis suggest a potential for the development of selection programs based on coping styles that could increase seabass welfare without altering growth performances. Overall, it also contributes to a better understanding of the origin and the significance of individual behavioral differences.

title: Budget and staff for management and protection of coastal environment; wastewater management; response to green algae blooms

description: The data presented herein are focused on marine and coastal environment management and protection costs as measuring the state's effort in terms of budget and staff in this domain. There is a considerable diversity of actions for marine and coastal envrionment both at the level of the state and of local authorities. So the picture given by the data remains partial. Budget data as sourced from yearly budgets indicate the main actions and there cost in terms of state expenditure. In addition the Environment Satellite Accounts provide data on waste water management (with obvious impacts of the state of sea waters). An example of local problem is analysed in terms of cost: green algae blooms are managed at local level, and collection requires a sizeable budget as shown using data from CEVA Center for Seaweed Study and Processing.
