Modeled distribution map of Kophobelemnon stelliferum assemblage in the North East Atlantic in 2021

Modelled density of the seapen Kophobelemnon stelliferum in the North East Atlantic. The Random Forest density model trained on data collected by an ROV was constrained by an ensemble of Maxent and Random Forest presence-absence model trained on a larger dataset also collected by an ROV. This species provides structural complexity in an environment where it is lacking and, thus, promotes higher biodiversity where they settle. They are vulnerable to mechanical disturbance of the sediment by fishing gear and a better understanding of their distribution will lead to better management of their population. This work was performed at the University of Plymouth in 2021.
5921_CNR_West Sardinia_64

Bathymetric grid generated from dataset collected along the western and northern margin of the Sardinia Island (western Mediterranean Sea) during several oceanographic cruises, aimed at mapping geohazard-related features of the Italian seafloor (https://www.protezionecivile.gov.it/en/approfondimento/progetto-magic-marine-geohazards-along-italian-coasts-0/). 
Data were collected by means of the MBES system Kongsberg EM 3002D (293-307 kHz) for shallow areas, and Kongsberg EM 710 (200 kHz) and SeaBatReson 7111 (100 kHz) for deeper areas, and were processed using the software Caris Hips and Sips and Teledyne PDS.
Modeled density map of Syringammina fragillissima at a fine scale from the Rockall Bank in North East Atlantic between 1981-2010

Fine scale density map of the xenophyophores Syringammina fragillissima (ind. m-2) at a 1200m deep station off Rockall Bank (North East Atlantic) by The University of Plymouth for the Deeplinks project. The drivers of the distribution of this species are poorly known despise its Vulnerable Marine Ecosystems (VME) status and more knowledge on its biology is needed to efficiently manage its conservation. A Convolutional Neural Network was used to measure its density in 58,147 images collected by the AUV autosub6000 during the JC136 cruise in May 2016. Several environmental data layers (topographic and oceanographic) at 2.5 x 2.5 m resolution were collected by the AUV during the same cruise and used in the modelling. Random Forest regression was used to predict the density of the target species in the extent of the environmental layer representing around 3 km2.
Historical records of the past distribution, extent and form of European native oyster (Ostrea edulis) reef ecosystem

This dataset assembles historical information existing in public and private documentary archives. Taken together, these data contribute to the building of a knowledge base of the historical presence, extent and biogenic formations of European flat oyster ecosystems prior to and during the intensification of bottom fishing activities. To identify and recover such information requires significant resources and expertise. The establishment of a Historical Ecology Working Group under the umbrella of the Native Oyster Restoration Alliance in early 2020 presented a unique opportunity to coalesce interdisciplinary expertise and resources from multiple European countries to collate and interrogate historical data sources. To date, this is the only known dataset that evidences the past distribution, extent and characteristics of this seabed ecosystem across its full biogeographic range. 
The described datasets present qualitative and quantitative extracts from written records published between 1524-2022, which show: (1) estimated locations of past oyster fisheries and/or reef habitat across its full biogeographical range, with associated levels of confidence; (2) recorded extent of past reef habitats, and; (3) species associated with these habitats. 
This comprehensive historical analysis demonstrates that oyster reefs were once a dominant three-dimensional feature along much of the European coastline and some shallow shelf seas.

Microplastic measurement campaign during The Ocean Race Europe 2021 from the racing yachts AmberSail2 and AkzoNobel by GEOMAR Kiel.

The provided microplastic dataset was generated during The Ocean Race Europe in May-June 2021. The samples were collected onboard two 65’ one-design yachts known as VolvoOcean65, called AmberSail2 and AkzoNobel Ocean Racing in the Baltic Sea, North Atlantic Ocean and Mediterranean Sea. 
The instruments used for underway measurements  were the same as used in Tanuha et al., 2020. The system consists of a specially built OceanPack RACE manufactured by SubCtech GmbH in Kiel, which was connected to a microplastic filtration unit built by bbe Moldaenke GmbH. (Data submission https://www.emodnet-ingestion.eu/submissions/submissions_details.php?menu=39&tpd=232&step=0103_001volvo%20ocean%20race). 
The mixed-layer surface water (~1.5 m depending on the heel of the yachts) was sampled in the Baltic Sea, North Atlantic Ocean and Mediterranean Sea. The laboratory analysis of collected samples was undertaken by GEOMAR (Kiel), under the supervision of  Aaron Beck and Toste Tanuha.  
The data variables includes GPS positions, time, temperature, salinity,  flow rates and durations, sample ID, measured microplastic fiber, fragments and total concentration in [particles/m³]. Respetive concentrations of fiber and fragments are also provided for different colors: blue,red, orange, pink, yellow, green, black, clear, purple, grey, brown.

High-frequency logger data

In this study, we utilized high-frequency open-water measurements of oxygen, temperature, salinity and wind speed to investigate temporal and spatial variability in estuarine metabolism at sites with different benthic habitats and at different water depth. This enabled us to characterize the seasonality in GPP, R and NEP and investigate the regulating importance of different external conditions over different time scales. A series of benthic and pelagic oxygen in situ incubation studies furthermore allowed assessing the benthic and pelagic contributions to the ecosystem-integrated rates. Multiple measurements along a depth gradient made it possible to test expectations of larger magnitude and variability of ecosystem metabolism in shallow eelgrass-dominated areas compared to deeper muddy parts of the estuary. These measurements along a depth gradient ultimately enabled us to evaluate the influence of meteorological forcing events for short-term oxygen dynamics. The study was conducted in the southern, inner part of Roskilde Fjord, from April to December in 2015.
Two of the sites were located at 2-3 m depth, one representing an eelgrass meadow and another, approximately 100 m to the south, representing a neighboring non-eelgrass habitat. The latter is referred to as the “Bare” site, although the habitat had scattered small stones (5 – 10 cm in diameter) covered by filamentous algae. The third site (“Muddy”) represented the deeper (5 m) habitat characterized by fluffy organic-rich sediment and no benthic vegetation. In addition, for quantifying short-term effects of physical forcing, we conducted a gradient study along a transect perpendicular to the shoreline (from ~100 to 500 m off the shore) starting at 1.8 m and reaching ~5 m depth.
Continuous measurements (every 10 min) of dissolved oxygen (DO) and water temperature were made with miniDOT oxygen optode loggers (Precision Measurement Engineering, Vista, CA, USA, in the following termed “oxygen logger”) at the three main sites.
The chamber incubations were done in triplicates and at the three types of habitat in April, June and August, corresponding to mean temperatures of 9, 16 and 21°C, respectively. Chambers consisted of gas impermeable transparent plastic bags (19 x 42 cm; diameter x height = 12 L) attached to a hard PVC collar, which was secured firmly into the sediment with metal plugs. Incubations were made over a period of approximately 24 hours with logging of oxygen, temperature and light every 10 minutes by a oxygen logger and a light logger placed at a depth of about 30 cm above the seafloor inside each chamber fixed to a metal stick placed into the sediment.

The Green Edge cruise: following the evolution of the Arctic phytoplankton spring bloom, from ice-covered to open waters

The Green Edge project was designed to investigate the onset, life and fate of a phytoplankton spring bloom (PSB) in the Arctic Ocean. The lengthening of the ice-free period and the warming of seawater, amongst other factors, have induced major changes in arctic ocean biology over the last decades. Because the PSB is at the base of the Arctic Ocean food chain, it is crucial to understand how changes in the arctic environment will affect it. Green Edge was a large multidisciplinary collaborative project bringing researchers and technicians from 28 different institutions in seven countries, together aiming at understanding these changes and their impacts on the future. The fieldwork for the Green Edge project took place over two years (2015 and 2016) and was carried out from both an ice camp and a research vessel in the Baffin Bay, Canadian arctic. Here, we describe the data set obtained during the research cruise, which took place aboard the Canadian Coast Guard Ship (CCGS) Amundsen in spring 2016.

Array of Ocean Bottom Tilt Current Meters: data from the EMSO-Azores observatory, 2021-2022

This dataset contains current data acquired between june 2021 and June 2022 using 5 TCM-3 Ocean Bottom Tilt Current Meters installed next to the Tour Eiffel, Montségur and Crystal hydrothermal vent sites. The TCM-3 Ocean Bottom Tilt Current Meter from Lowell Instruments LLC (North Falmouth, MA, USA) measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Drag from moving water tilts the logger in the direction of flow. The logger’s accelerometer and magnetometer channels are used to record the amount of tilt and direction of tilt (compass bearing). The array comprises 6 TCM-3  currentmeters, deployed near the Tour Eiffel, Montségur and Crystal hydrothermal vent sites. It is not connected to an energy node. The currentmeter's internal clocks are set to UTC time before deployment. Clock drift after recovery is not implemented in data but added as metadata in the (metadata file)-[https://www.seanoe.org/data/00800/91238/data/97068.pdf]. Data are provided for each deployed instrument as two text files: current data temperature data

HIPPO environmental monitoring: Impact of phytoplankton dynamics on water column chemistry and the sclerochronology of the king scallop (Pecten maximus) as a biogenic archive for past primary production reconstructions

Given the importance of phytoplankton for marine ecosystems (oxygen production, carbon sequestration, base of food webs, etc.), many studies focus on the reconstruction of its past temporal dynamics. Over the last decades, important changes of these dynamics have been observed, both in the phenology of the blooms and in the composition of microalgal communities. However, currently available data do not allow to go back far enough in time to quantify the actual impact of anthropogenic activities on these changes. However, the structural and/or chemical studies of the shell of the king scallop, Pecten maximus, hold the potential to cover this lack of data and provide informations about the environment they experienced. In order to better understand the processes which drive the incorporation of chemical elements into scallop shells and their links with phytoplankton dynamics, an environmental monitoring was conducted at Lanvéoc (Bay of Brest; France; 48°17'39"N - 04°27'12"W) between March and October 2021. During this survey, water samples from surface and bottom layers were collected in a bi-weekly or a weekly basis in order to analyse various environmental parameters (nutrients, phytoplankton dynamics, trace element concentration in the particulate and dissolved fraction, particulate organic carbone and nitrogen, chlorophyll, pheophytin, biogenic silicon, etc.). A sediment trap has also been used to better understand the chemical dynamics of the sedimenting matter. Simultaneously, several instruments, such as an Underwater Vision Profiler (UVP6) and sambat probes, were deployed at Lanvéoc throughout the year and continuously recorded additional parameters (particle concentration, temperature, salinity, pH, dissolved oxygen, etc.). Furthermore, scallops which experienced one winter season (age-class I) were deposited at the beginning of the survey both in direct contact with the substract and in a cage, located 1 m above it. At the end of the monitoring, these scallops were recovered and their growth rates as well as the chemical composition of their calcitic stuctures were measured in a daily basis. In addition to the objectives of the HIPPO project, the dataset that is available here can potentially be very useful for other scientists performing sclerochronological investigations, studying biogeochemical cycles or conducting various ecological research projects.

Hydrographic dataset from the Eurofleets+ SINES 2022 research cruise in the Iberian Upwelling System

This dataset contains the hydrographic data for all the stations conducted during the EUROFLEETS+ SINES cruise that took place aboard the R/V Sarmiento de Gamboa between 11-20th of September 2022.  The project "Climate change impact on ocean fronts ecosystems: The case of the Iberian Upwelling System (SINES)" was planned to be a proof of concept cruise of multidisciplinary research: integrating satellite data to past sediment records within classical methods in oceanography research and automated underwater vehicles to tackle the characterization of the Iberian Margin Upwelling System. The overall objective of this study is to identify the changes and risks for marine ecosystem services deriving from the potential impact of climate change on upwelling fronts. This research cruise was funded by the Eurofleets+ SEA Programme Call “REGIONAL” in 2019/2020 and was led by the Centre of Marine Sciences of Algarve (CCMAR, Portugal). The proposed multidisciplinary expedition was carried out between 11-19th September 2022. Full depth water column CTD profiles were collected at all the stations (15 stations, 19 CTD casts, i.e, four stations with double cast -shallow and deep-). In 12 stations, a vertical multinet haul was also collected. The depth of the multinet samples (100 µm mesh) range between 700 m and surface. A deployment of a Light Autonomous Underwater Vehicle (LAUV Explore-4) was done on 17-18th of September. The AUV conducted more than 100 high-resolution immersion profiles between the surface and 10/50/100 m depth following the track of the research vessel between the coast and the position 37.35ºN 9.4ºW. Complete list of stations, events and positions of EUROFLEETS+ SINES also available in the dataset.
