title: Systematic conservation planning for the North-Atlantic deep sea

description: This dataset was built to feed a basin-wide spatial conservation planning exercise, targeting the deep sea of the North Atlantic, in the framework of the ATLAS H2020 project. This approach aimed to inform Marine Spatial Planning and conservation initiatives for the deep sea of the North Atlantic, by identifying conservation priority areas for the Vulnerable Marine Ecosystems (VMEs) and deep fish species and discussing the efficiency of the current spatial management context relatively to conservation stakes. This publication provides (1) the links to spatial datasets used as an input, (2) the R scripts used to run the final conservation scenarios together with associated table of targets and connectivity matrix, that can be run on the input data, and (3) the outputs of the final scenarios constructed and computed for ATLAS. Produced by IFREMER.

title: JERICO-NEXT TNA: Intercomparison of instruments for carbonate system measurements (INTERCARBO)

description: Continental margins are among the most biologically active areas on Earth. Although they cover only a small portion of the oceans, they contribute up to 15% of ocean primary production, are responsible for over 40% of the total oceanic carbon sequestration and for the vast majority of commercial fisheries. Carbon fluxes in coastal seas are more complex than those in the open ocean, in part due to high spatiotemporal variability in biological activity and physical processes. In the European coastal areas, complications also rise from the highly variable hydrography: sea surface temperature may vary from below zero degrees on the coast of Spitsbergen up to 30°C in the Mediterranean Sea, while salinity varies from 0 ‰ at the Bothnian Bay, the Baltic Sea, up to more than 38 ‰ in the Mediterranean Sea. This large variability creates challenges related to instrument accuracy, reliability and maintenance. As there are only a limited number of instruments available for such a highly variable range of environmental conditions, different research groups have often built their own instruments or modified the commercial instruments suitable for their own needs. This has led to a situation which sometimes makes assimilation of the data observed in different areas challenging. The aim of the INTERCARBO experiment, partly funded by TransNational Access (TNA) of H2020 infrastructure project Joint European Research Infrastructure network for Coastal Observatory – Novel European eXpertise for coastal observaTories (JERICO-NEXT) was to bring together a large number of carbon dioxide partial pressure (pCO2), pH and total alkalinity sensors used on European coastal seas and to compare measurements using different sensors on the same seawater samples. During the activity, 17 experiments were carried out in three 1 m3 tanks that were filled with seawater that was obtained from Oslofjord. The seawater was manipulated in order to meet predetermined physical and chemical properties. Three salinity conditions (5, 20, and 35 PSU) were generated by introducing fresh water from a local well. Three carbon dioxide target values of approximately 200, 400, and 800 parts per million (ppm) were targeted by equilibrating the water with the corresponding CO2 gases (due to high alkalinity and limited duration of the experiment, these target values were not always reached). The measurements were made on seawater at 10 °C and 20 °C. This data set presented here contains currently available pCO2 and pH data from the experiment, together with sensor meta data describing the instruments.

title: JERICO-NEXT TNA: MicroPlastox - sampling of microplastics and toxicity assessment

description: Defined as plastic particles &lt;5mm [1], microplastics (MP) are present in many household items and are also formed due to the cracking and embrittlement of larger plastic particles. Owing to their inherent physical and chemical characteristics, MPs are persistent and ubiquitous aquatic contaminants that can be potentially ingested by benthic and planktonic organisms, thus entering food webs [1]. Additionally, studies have shown that the microbial communities that colonize these materials differ enormously from the indigenous free-living marine communities [2]. This could pose a significant threat not only to biodiversity, as microbial “hitchhikers” may constitute invasive species, but also to humans, due to increased exposure in bathing waters and beaches [3]. All these threats are further exacerbated by these materials’ characteristic high surface area-to-volume ratios. Other contaminants, namely, persistent organic pollutants, can be adsorbed by these particulates and result in bioaccumulation and bioamplification phenomena [4]. Therefore, a detailed quantitative and qualitative monitoring of microplastics and their effects in the marine environment is highly recommended by the Marine Strategy Framework Directive (MSFD) [5]. Considering that the physicochemical properties of microplastics affect their transport and bioavailability in the environment [6], an evaluation of their ecotoxicological effects becomes of paramount importance. Hence, the assessment of potential ecotoxicological effects is also proposed, resorting to standardized methodologies which will be adapted towards the evaluation of MP toxicity. Hence, the goals of this project are: 1) Collection, cataloguing and storage of microplastics from aquatic systems; 2) Understanding their degradation behaviour, including lifetimes and fate; 3) Filling the knowledge gap pertaining to the ecotoxicological effects of MP in the environment; 4) Contribute with key information to the development of water policies and management strategies. The MSFD acknowledges a limitation in the “knowledge of the accumulation, sources, sinks (…) environmental impacts (…) and potential physical and chemical impacts” of microplastics. As such, the prospective results will contribute to the understanding of the presence and impacts of microplastic pollution and provide insights into potential routes across the Euro-region, greatly benefiting the environment, coastal populations’ health and activities, including recreation, tourism and fisheries.

title: "Characterization of sound scattering layers in the Bay of Biscay using broadband acoustics, nets and video" acoustics and biological Data

description: Sound scattering layers (SSLs) are observed over a broad range of spatio-temporal scales and geographical areas. SSLs represent a large biomass, likely involved in the biological carbon pump and the structure of marine trophic webs. Yet, the taxonomic composition remains largely unknown for many SSLs. To investigate the challenges of SSL sampling, we performed a survey in a small study area in the Northern Bay of Biscay (France) by combining broadband and narrowband acoustics, net sampling, imagery and video recordings. In order to identify organisms contributing to the observed SSLs, we compared measured frequency spectra to forward predicted spectra derived from biological data. This dataset comprises the echo-integrated broadband acoustic data (in Sv(f)), the nets position and depth, and the abundance and the size of the catched organisms acquired during a specific operation of SSLs sampling during PELGAS 2016. The acoustic data have been echo-integrated by cells of 5 ping in horizontal and 1.5 meter in vertical. The biological data comes from video counting, direct measurement, ZooCAM or ZooScan plankton imagerie tools; they were generally identify at a low taxonomic level, but sufficient for the modelisation of their acoustics backscattering. More detail of the biological/acoustical data acquisition and processing can be find in Blanluet et al., (under review). This dataset was used in Blanluet et al..

title: Data from: Connectivities with shellfish farms and channel rivers are associated with mortality risk in oysters

description: Two age-classes of Pacific oysters (Crassostrea gigas), i.e. young and adult, were used as sentinels to monitor mortality in the Baie des Veys (Normandy, France) from mid-April to October 2014. Oysters were deployed at 39 sites spread over a 37 km2 surface area inside and outside of the shellfish farms. Each site was visited 9 times (12-15 May, 13-16 June, 26-30 June, 12-18 July, 27-29 July, 11-14 August, 25-27 August, 9-12 September, 16 October 2014) during spring tides. For young oysters, cumulative mortality obtained in September is provided. For adult oysters, cumulative mortality is provided for 2 periods: from mid-April to mid-July (Period 1) and from mid-July to October (Period 2). A validated 3-D hydrodynamic Model for Applications at Regional Scale (MARS-3D) coupled with a biogeochemical model (ECOMARS-3D) was used to generate high frequency data of seawater temperature, salinity, chlorophyll a concentration (derived from phytoplankton) and hydrodynamic connectivity to oyster farms and to the mouths of the channel rivers at the 39 sites. For seawater temperature, salinity and chlorophyll a, the minimum, maximum and mean values of hourly data are provided for the whole study period as well as the mean of daily mean or median of daily median for Periods 1, 2 (used for adult oysters) and the period from mid-April to September (used for young oysters). Hydrodynamic connectivities to river channels (Carentan and Isigny) and shellfish areas (Grandcamp and Utah Beach) were estimated in February, May and August 2014. This database is part of the ANR GIGASSAT project No. ANR-12-AGRO-0001.

title: Fortune Bay (NL, Canada) oceanographic observations May 2015 - May 2017

description: A comprehensive set of oceanographic data were collected in Fortune Bay, a broad, mid-latitude fjord located on the south coast of Newfoundland (Canada). The dataset was gathered in partnership with IFREMER who collected data around the adjacent French archipelago of Saint-Pierre and Miquelon. The dataset consists of data from taut-line moorings, land-based stations (a tide gauge and a couple of weather stations) and CTD profiles performed during mooring maintenances (~every 6 months). Parameters covered by the moorings include water column temperature (thermistor chain), salinity (2 points/depths per mooring), dissolved oxygen (on a limited number of moorings, within the surface layer) as well as current profiles (ADCP). Land-based stations monitored water level and temperature (tide gauge) and wind speed and direction, atmospheric pressure, air temperature and solar radiation (weather station). CTD profiles include dissolved oxygen for the most part. The program lasted two full years from May 2015 to May 2017 and sampling interval varied from 1-60 min depending on the instrument.

title: Real time monitoring bivalve behavior

description: ReMoBiB (remote monitoring of bivalve behavior). The project aimed at deploying a so called valve gape monitor and connect it to a underwater node to generate an continuous online accesible data stream of valve gape measurement. The project aimed to demonstrate the possibility to use shell valve gape as a bio-monitor in addition to monitoring of more traditional environmental monitoring techniques. At the same time we wanted to test the possibility to connect this equipment to the COSYNA underwater node at Helgoland. For this, the existing stand alone equipment developed by NIOZ had to be adapted to enable connection and data tranfer. The scientific aim of the project was to establish the relationship between shell gape (filtration activity) of Arctica islandica and environmental factors (Salinity, Temperature, Chlorophyll, light) at the southern limit of its distribution. This is done by collecting a continuous observational time series on shell gaping behaviour covering at least an entire year, while at the same time high resolution environmental data are being collected from the underwater node to which the gape recorder is connected. Within the project it is aimed to develop an online visualisation of real time valve gape activity on the NIOZ and AWI website as means to raise awareness about sea life among the broader public and show that the shells are living creatures reacting to their environment.On the longer term the online monitoring of the gaping behaviour of bivalves adds an extra dimension to environmental monitoring especially for ecological studies. Results are likely to illustrate the role of (extreme) environmental conditions on the feeding behaviour of individuals and the variation therein. It is anticipated that this project will lead to intensified cooperation and joint benthic ecological studies between NIOZ and AWI. Valve gape has been determined by measuring the electromagnetical field between two electronic coils glued on to the shell at the siphon side of the shell. The strength of the electromagnetic field between the coils is a measure for the distance that the coils are separated and thus how far the both valves are apart from each other. Valve gape is expressed as fraction open, i.e. for comparison of different animals the signals are rescaled to vary between 0 and 1. Valve gape opening has been measured with a ~1 second frequency. These ultra high resolution data have been saved and collected in data files representing 1 hour periods. For data analyses the "seconds" data have been aggregated to minute data by calculating the average valve gape in that minute.

title: Experimental database of the flow past a wall-mounted square cube

description: In high flow velocity areas like those suitable for tidal applications, turbulence intensity is high and flow variations may have a major impact on tidal turbines behaviour. Large turbulent structures are present in the water column and may interact with the tidal turbine. The Reynolds number, based on the rugosity height and mean flow velocity, is rather high in this context: Re=2.5x107. For that purpose, experiments are carried out in a flume tank with Re as high as achievable in Froude similitude (in the tank: Re=2.5x105 and Fr=0.23) in order to study the wake past seabed obstacles. The obstacle is here a canonical square wall-mounted cube chosen to be representative of specific in-situ bathymetric variations. To represent the variability of turbulent in-situ conditions, different upstream turbulence rate are achieved. Using PIV and LDV measurements, the flow past the cube is investigated. The experimental database is presented in this report.

title: Pinfish Database: The Florida Fisheries-Independent Monitoring (FIM) programs Pinfish data from Eastern Gulf of Mexico estuaries

description: Sound management is necessary to preserve the health of Florida's marine environments for our present and future enjoyment. Florida's Fisheries-Independent Monitoring program (FIM) informs mangers on abundance trends of fisheries resources in Florida waters. Stratified-random sampling in estuarine habitats has been conducted since 1989 with the goals of estimating nekton abundance and describing population trends in estuarine regions throughout Florida. Three gear types are deployed: 183-m haul seine with 37.5-mm stretch mesh, 21.3-m center-bag seine with 3.1-mm delta mesh, and 6.1-m otter trawl with 37.5-mm stretch mesh and a 3.1-mm delta mesh liner in the bag. All species of nekton (crabs, shrimp, and fish) collected are identified to the lowest practical taxonomic level, enumerated, and a representative subsample of lengths are measured. Location (latitude, longitude, depth), weather (wind direction/speed, tide), date/time, habitat characterizations (bottom substrate, submerged aquatic vegetation, shore type) and water quality parameters (temperature, conductivity, salinity, pH, dissolved oxygen) are recorded at each sampling site. Sampling is conducted with a monthly periodicity during daylight hours (one hour after sunrise to one hour before sunset). Database Contents: This is a subset of the Florida FIM program data (1998 - 2016) used to assess population trends, estimate growth, and describe habitat use of Lagodon rhomboides (Pinfish) in four Gulf of Mexico estuaries (Apalachicola Bay, Cedar Key, Tampa Bay, and Charlotte Harbor. Data include abundance (animals/100m2), biomass (grams/100m2), and Standard-Length measurements (millimeters) of Pinfish with associated habitat (Bottom Vegetation Percent Cover, Salinity), water quality (Temperature, Salinity, Depth) and temporal (Year, Month) variables. Methods: Pinfish were collected each month between 1998 and 2016 using a 21.3-m center bag seine with 3.2-mm mesh in Apalachicola Bay, Cedar Key, Tampa Bay, and Charlotte Harbor. A stratified-random sampling design was used to select sites to be sampled each month. Water quality measurements (temperature, salinity, conductivity, pH, and dissolved oxygen) were recorded with either a Hydrolab© or YSI© water quality sonde at each sampling site. Habitat characterizations were also recorded for each site. The seine was deployed in a consistent manner, with an estimated 140m2 of bottom area sampled by each net haul. All Pinfish were identified, counted, and a representative subsample were measured for Standard Length (mm).
