EC1, Subsurface mooring time series from 2020 to 2023

EC1 is a subsurface mooring that has been deployed in the Ulleung Interplain Gap (UIG) since 1996. The UIG is the only deep channel connecting the northern Japan Basin and the southwestern Ulleung Basin in the East Sea (Japan Sea). The EC1 provides continuous time series data at depths ranging from 150 to 2,250 meters, enabling scientific research on circulation and water properties. It equips current-meter, conductivity, temperature, pressure, and dissolved oxygen sensors. The EC1 mooring was recovered 3 times (26 times total) and redeployed 3 times (26 times total) from November 2020 to April 2023 (since 1996), with a typical turnover time of 1 year. The equipment has been upgraded since 1996 to continuously measure temperature, pressure, conductivity, dissolved oxygen, and the speed and direction of three-dimensional current, as well as to collect more and better time series data. The sampling intervals of all sensors are equal to or less than 60 minutes. The temperature, pressure, conductivity, and dissolved oxygen data collected from November 2020 to April 2023 were quality-assured and quality-controlled with typical procedures such as global and local range tests, spike tests, and gradient tests. The magnetic declination of 9 degrees west was applied to the current data for compass calibration.

Winter distribution of zooplankton and ichthyoplankton assemblages in the North Sea and the English Channel

Although zooplankton was extensively studied in the North Sea, knowledge about winter zooplankton assemblages is still scarce, despite potential influence of zooplankton overwintering stocks on seasonal plankton succession and productivity. Furthermore, several economically and ecologically important fish species reproduce during winter contributing to the zooplankton community as passive members (eggs) or predators (larvae). To shed some light on winter zooplankton distribution, abundance and composition in the Southern North Sea and Eastern English Channel, we defined assemblages based on mesozoo- and ichthyoplankton data sampled between January and February 2008 using fuzzy-clustering and indicator species. Mesozoo- and ichthyoplankton (eggs+larvae) were integrated in a common analysis by using a spatial grid adapted to the datasets and defined by means of a geostatistical method developed in agronomics. Potential environmental drivers of assemblage distribution were evaluated by means of GLMM and comparison with data from 2022 facilitated insight about the inter-annual representativeness of the assemblages. Five zooplankton assemblages were found varying with regard to total zooplankton abundance, dominant and indicator taxa. Spatial variability of abiotic (dissolved nutrients, salinity, depth, temperature, organic matter in suspension, chlorophyll a), biotic variables (phyto- and microplankton composition), water masses and fish spawning grounds were revealed as potential drivers of assemblage distribution. Assemblages off the Rhine-Scheldt estuary and in the German Bight harbored the biggest zooplankton overwintering stocks that might influence the grazing pressure on phytoplankton spring production. Assemblages off the Rhine-Scheldt estuary and covering the English Channel and the Southern Bight were found to be of high importance for herring and plaice larvae. Although further analyses suggested inter-annual representativeness of the assemblages found (2008 vs 2022), the assessment of further years would be necessary to account for potential inter-annual variability. Future studies could profit from the assessment of microzooplankton facilitating insight in fish larvae feeding potential and zooplankton overwintering strategies.

MEPA Coastal Water Survey - Pollutants in sediment 2012

The survey was conducted at 17 stations in the coastal waters of the Maltese Islands in 2012. Sediment samples were collected using a Van Veen grab sampler. The collected sediment was collected in a container of adequate size, photographed and immediately sampled. At each station two samples were collected in order to execute and compare two chemical analyses. These were placed in a cool box and transported to the warehouse and stored in a refrigerator. Later, they were shipped by express courier to the laboratory  within 3 working days. The samples were analysed for the level of pollutants using International Organization for Standardization and US Environmental Protection Agency standard procedures. The pollutants tested for are important metals, hydrocarbons and PAHs and persistent organic compounds that can cause bioaccumulation. The measurements were made in connection with a monitoring survey of Maltese coastal waters. The resultant datasets generated provide the benchmark for long term monitoring programs and assessments that are required in order to implement EU Directives on water resources.
The 2014 Greenland-Portugal GEOVIDE bottle data (GO-SHIP A25 and GEOTRACES GA01)

The GEOVIDE cruise was carried out coast to coast between Portugal and Newfoundland via the south tip of Greenland, following the OVIDE line in the eastern part and crossing the Labrador Sea in the western part. The classical hydrographic rosette was cast 163 times at 78 different geographical positions called stations. While the CTD-O2 probe acquired continuous profiles of the “physical” variables (pressure, temperature, salinity and dissolved oxygen), 22 Niskin bottles were closed at different levels during the upcast to provide samples for biogeochemical analysis. After calibration, we find precisions for pressure, temperature, salinity and dissolved oxygen that fit the GO-SHIP international quality requirements. In parallel, but not simultaneously, a trace-metal rosette (TMR) was cast 53 times, also acquiring profiles of physical variables, and equipped with 24 Go-Flo bottles adapted for the sampling of trace metals. Depending on the number of operations, stations were identified as “Short” (one single CTD cast), “Large” (3 CTD casts), “XLarge” (up to 6) and “Super” (up to 11). All along the track of the ship, current magnitude and direction was measured by Ship Acoustic Doppler Current Profilers, down to 1000m depth.

This dataset reports for the classical rosette bottle data for the following Essential Ocean Variables: salinity, dissolved oxygen, total alkalinity, pH, nitrates and silicic acid. It also reports on the measurements of the CTD-O2 probe at the bottle levels: pressure, temperature, salinity and dissolved oxygen.

Deep moored current and hydrographic measurements in southwestern East Sea (Japan Sea)

Time-series data from subsurface moorings, U5 and UB2, and vertical profile data of conductivity-temperature-depth (CTD) were collected in the southwestern East Sea (Japan Sea). The moored current-meter data were collected using rotary-current meters (RCMs) at U5 at depths of 1000 and 2000 m from November 2002 to May 2006 and at UB2 at depths of 1000 and 1600 m from May 2006 to February 2010. Sampling intervals of the RCMs were 30 minutes or an hour. Six vertical profiles of temperature and salinity were collected using standard CTD instruments near U5 in August 1995, March 1997, June 1999, September 2005, August 2008, and October 2012. The data were quality controlled and quality assured before provision to the community via SEANOE.

A broad-scale long-term dataset of Sabellaria alveolata distribution and abundance curated through the REEHAB (REEf HABitat) Project

Numerous reef-forming species have declined dramatically in the last century, many of which have been insufficiently documented due to anecdotal or hard-to-access information. One of them, the honeycomb worm Sabellaria alveolata (L.) is a tube-building polychaete that can form large reefs, providing important ecosystem services such as coastal protection and habitat provision. It ranges from Scotland to Morocco, yet little is known about its distribution outside of the United Kingdom, where it is protected and where there is a strong heritage of natural history and sustained observations. As a result, online marine biodiversity information systems currently contain haphazardly distributed records of S. alveolata. One of the objectives of the REEHAB project (https://www.inaturalist.org/). 80% of these records were not previously referenced in any online information system. Additionally, historic field notebooks from Edouard Fischer-Piette and Gustave Gilson were scanned for S. alveolata information and manually entered.  Each of the 21512 S. alveolata records were checked for spatial and taxonomic accuracy, particularly in the English Channel and the North Sea where incorrectly identified observations of intertidal Sabellaria spinulosa were recorded. A further 54 observations are recorded as ‘Sabellaria spp.’ as the available information did not allow for an identification to species level. Many sources reported abundances based on the semi-quantitative SACFOR scale whilst others simply noted its presence, and others still verified both its absence and presence. The result is a curated and comprehensive dataset spanning over two centuries on the past and present global distribution and abundance of S. alveolata. Sabellaria alveolata records projected onto a 50km grid. When SACFOR scale abundance scores were given to occurrence records, the highest abundance value per grid cell was retained.

Sailing on the bloom in north-east atlantic in spring 2019 for collecting sea surface parameters

iodysséus ((https://www.iodysseus.org)-[https://www.iodysseus.org/]) is an offshore sailing ship equiped as an oceanographic platform. Data have been collected  during 3 legs (around 3500 nautical miles in total) during the spring 2019. The navigation zones are on biological phenomena, corresponding to the zones where the CO2 varies widely, thus measurements taken provide extra information to help restrict seasonal variability and the seasonal CO2 cycle (and help to calculate the rate of ocean acidification). (During the spring, the partial pressure of CO2 decreases during bloom phenomenon because planktonic microorganisms pump CO2 for their growth). The physico-chemical parameters of the surface water have been continuously measured thanks to an Ocean Pack : temperature, salinity, dissolved oxygen, chlorophyll-a concentration, and partial CO2 pressure (pCO2). (This device was developed and adapted for racing yachts. Both compact and light, it consumes very little energy. One of its many advantages is that it can still operate at speeds above 15 knots. It shows that modern oceanography is evolving towards more flexible models). leg 1: from 19-04-21 to 19-04-24 leg 2: from 19-05-13 to 19-05-21 leg 3: from 30-05 to mid june Three maps below: partiel pressure of CO2 (ppm) Image Reference: https://www.seanoe.org/data/00612/72407/illustrations/illustration-80.gif.

Oceanic carbonate chemistry measurements from discret samples collected at the SOLEMIO station (Bay of Marseille - North western Mediterannean Sea) between 2016 and 2019

This dataset  reports ocenanic CO2 parameters measured on discret samples collected at the SOLEMIO station (Bay of Marseille - North Western Mediterranean Sea - aprox. 65 m depth). The SOLEMIO station is part of the French national network of coastal observation SOMLIT (Service d’Observation en Milieu LITtoral – http://somlit.epoc.u-bordeaux1.fr/fr/). Measurements of carbonate chemistry parameters are not routinely measured within the framework of the SOMLIT network. This datased reports fortnightly measurements collected during three years (between june 2016 and june 2018) at three different depth in the water column (Surface, intermediate and bottom). This dataset is constituted of measurements of total alkalinity, total inorganic carbon and pH (on the total scale). Dissolved oxygen concentrations, inorganic nutrients, temperature and salinity (SOMLIT core parameters) are also reported.

AdriFOOS Depth/Temperature profiles dataset 2012-2020

From 2003 to 2013, the Ancona section of CNR-IRBIM (formerly part of CNR-Institute of Marine Science) runned the “Fishery Observing System” (FOS) program aimed at using Italian fishing vessels as Vessels Of Opportunity (VOOs) for the collection of scientifically useful datasets ((Lucchetti et al. 2018)-[http://doi.org/10.1016/j.marpol.2018.09.031]). In 2012, thanks to the participation to some national and international projects (e.g. SSD-Pesca, EU-FP7 JERICO etc.), CNR started the development of a new modular “Fishery & Oceanography Observing System” (FOOS; (Patti et al. 2016)-[http://dx.doi.org/10.1080/1755876X.2015.1120961]). CNR-IRBIM implemented the “AdriFOOS” observational system, by installing the FOOS on some commercial fishing boats operating in the Adriatic Sea. Since then the datacenter based in Ancona receives daily data sets of environmental parameters collected along the water column and close to the sea bottom (eg. temperature, salinity, etc.), together with GPS haul tracks, catch amounts per haul, target species sizes and weather information. Some temperature and salinity measurements acquired by the FOOS in the Adriatic Sea from January 2014 to March 2015 were published within the (NEXOS project)-[http://nexos.demo.52north.org/demo-client/#/profiles/selection]. The dataset here presented contains 14810 depth (pressure)/temperature profiles collected by 10 vessels of the AdriFOOS fleet in the period 2012-2020. All the profiles were subjected to quality control.Data are flagged according the (L20 (SEADATANET MEASURAND QUALIFIER FLAGS))-[http://seadatanet.maris2.nl/v_bodc_vocab_v2/search.asp?lib=L20].

Drifter deployment in the framework of the IMPACT (Port impacts on marine protected areas: transnational cooperative actions) project

The deployment was part of the IMPACT project ( http://interreg-maritime.eu/web/impact ) and performed in collaboration with the CMRE-NATO under the framework of a LOGMEC (Long-term glider missions for environmental characterization) experiment. 40 CARTHE-type drifters were deployed in the open sea, in front of the Gulf of La Spezia Gulf (Italy) on May 2, 2019. CARTHE-type drifters are biodegradable drifters, spanning the first 60cm of the water column (Novelli 2017, 2018, 2020). The deployment strategy consisted of releasing drifters on a regular grid (about 6km side and 1km step, with some 500m nesting) in a time window of about 2-3 hours. 5 drifters were released in line after passing by the Portovenere Channel, while exiting the Gulf of La Spezia. 5 drifters were collected nearby Toulon (France) on May 17, 2019 and 4 of them were redeployed in the same area on June 24, 2020 (logistical support by University of Toulon). Each file contains a drifter trajectory in the NetCDF format (ex: 001.nc, 002.nc, etc...). Trajectories of those drifters that were collected and re-deployed are splitted in different files (ex: 001_a.nc, 001_b.nc). Nominal drifter transmission rate: 5 minutes. Positions available until June 28, 2019. The dataset includes raw positions; outliers were removed.   References: • Novelli, G., C.M. Guigand, C. Cousin, E. Ryan, N. Laxague, H. Dai, B.

Spatial variability of organic matter and phosphorus cycling in Rhône River prodelta sediments (NW Mediterranean Sea, France): a data-model approach

The Mediterranean Sea (MS) is a large oligotrophic sea. Its productivity may be sensitive to riverine nutrient inputs. Understanding its productivity involves quantifying phosphorus (P) river supply which is crucial for calculating P mass balances in the anthropogenically disturbed sea. Yet the precise role of the deltaic filter is not known, especially concerning the  differential trapping/recycling of nutrients in deltaic sediments. A benthic dataset from the Rhône River prodelta was coupled to an early diagenetic model, including the benthic P cycle. The dataset comprised  porewater oxygen, nitrate, sulfate, dissolved inorganic carbon, ammonium, dissolved reduced and total iron, dissolved inorganic phosphorus (DIP) and solid data (organic carbon, Fe-bound P, Ca-bound P and organic P) for 9 stations from the Rhône River prodelta. The model results indicated that the intensity of biogeochemical processes occurring near the sediment–water interface decreased from the river mouth to the adjacent continental shelf. This decrease occurred according to OC fluxes to the seafloor, sedimentation rates and integrated rates of OC mineralization (from 160 mmol C m-2 d-1 near the mouth to 10 mmol m-2 d-1 on the shelf). The organic P mineralization was intense, especially near the river mouth (1196 µmol m-2 d-1), and its contribution to DIP release was large (> 90%). Fe-bound P had a key role in promoting Ca-bound P precipitation in anoxic sediments. These sediments played an important role as a source of regenerated DIP.A significant part of DIP was recycled to the overlying waters (72-94%), representing 25% of the riverine discharge input of DIP. While 6-28% of produced DIP was buried as Ca-bound P, which represented 3-6% of the riverine inputs.
