National monitoring data for beach litter from two Baltic Sea beaches in Denmark, 2020-21

This dataset represents a part of the Danish national monitoring data for marine litter at reference beaches in Denmark 2020 and 2021. The purpose of the monitoring program is to provide systematical and comparable data for assessment of the state, impact and trends of marine litter and thereby comply with the European Marine Strategy Framework Directive (MSFD). National monitoring of marine litter at beaches was initiated in Denmark in 2015, and on request from the Danish Environmental Protection Agency (EPA), and the monitoring activities involving these two beaches in the Baltic Sea are performed by DCE – Danish Centre for Environment and Energy.
The results of the monitoring surveys performed at these two beaches show that plastic comprised the majority of all beach litter items. The amounts of beach litter were in all regions above the EU threshold value of 20 litter items per 100 m beach length. Among some of the most common type of litter items were plastic pieces 2.5-50 cm, polystyrene pieces 2.5-50 cm and String and cord (diameter less than 1cm).

The dataset includes continuous velocity, direction, and depth measurements in 9 fixed locations (3x3 grid) in the Gulf of Riga, Baltic Sea. It is a space-time-aligned dataset of continuous velocity, direction, and depth measurements near Skulte, the Gulf of Riga, Baltic Sea (Eelsalu et al. 2025, Proceedings of the Estonian Academy of Sciences). All sensors measured 0.4m from the bottom of the sea.

The measurements are done using a Hall effect sensor-based velocity profiler called Hydromast (Egerer et al. 2024, IEEE sensors). The minimum velocity provided in this dataset is 0.12m/s, validated with ADV. If the velocity is under this threshold, the velocity and direction read NaN. The depth and temperature measurements are valid at all times.
MedFever : An expanding network of citizen-run observatories monitoring shallow coastal underwater temperatures in Italy

MedFever – An expanding network of 12 small observatories was established in the Tyrrhenian Sea in 2021 by MedSharks and ENEA, building on the experience of an observation point established in 2016 in the Gulf of Naples.  Very high frequency measurements (15 minutes) at some standard depths (5-15-35m; occasionally at 10-20-25-30-50-60m) were obtained by voluntary diving centers using calibrated HOBO sensors (after calibration accuracy is about ±0.1 °C) in 12 stations evenly covering the Tyrrhenian sea. Due to various technical problems, some records are missing. The dataset proposed here will be upgraded annually.

Complex climate dynamics across Heinrich Stadial 1: a new macro-regional pollen record from the NE Atlantic Ocean

We discuss vegetation and climate changes across western Europe over the last deglaciation, especially zooming on the Heinrich Stadial 1 (HS1) interval in the northern Bay of Biscay. Our study focuses on the marine palynological investigation of core MD13-3438, with new pollen analyses, here compared to a set of paleohydrographical marine proxies (including dinoflagellate cysts / dinocysts) obtained on the same core. We show that the recorded pollen signature is, at that time, tightly related to the fluvial dynamics of the ‘Fleuve Manche’ paleoriver, the latter being coupled with European Ice Sheet fluctuations, as well as influenced by fluvial deliveries from closer French rivers of the Atlantic coast. The onset of HS1 (18.2–16.7 ka BP), marked by enhanced ‘Fleuve Manche’ paleoriver seasonal runoff, is characterized by: i) two episodes of substantial fluvio-glacial input, concomitant with warmer summers and marked by increases of temperate forest pollen grain percentages; ii) and three episodes of moderate runoff, concomitant with extended colder winters and corresponding to increases of boreal forest pollen grain percentages. We suggest an important role of the variability of the North Atlantic atmospheric circulation in explaining those multidecadal changes in pollen sources recorded in the marine realm. When westerlies are deflected southward (respectively northward), they would bring higher humidity to the southern-western and closer (respectively northern-eastern and more distal) distributaries/rivers of the ‘Fleuve Manche’ paleoriver system, associated to moderate (respectively intense) runoff. Then, extreme cold and dry climate conditions are recorded at the onset of Heinrich Event 1 (16.7–15.6 ka BP) with marked occurrences of steppic pollen grains, followed by more humid conditions at the end of HS1, with mixed signatures of open-vegetation and temperate forest taxa. The wettest conditions are recorded during the Bølling-Allerød, concomitantly with the sea level rise and the advection of warm and salty waters by the North Atlantic Current to the study site.

Western Pomo Pit Pressure / Temperature / Salinity / Oxygen profiles Autumn dataset 2015-2021

The Central Adriatic Sea is characterized by three depressions collectively known as Pomo (or Jabuka in Croatian) Pits, with a maximum depth of about 270 m ((Marini et al 2016)-[https://doi.org/10.1016/j.margeo.2015.08.015]). In addition to being characterized by a very peculiar bathymetry and oceanographic characteristics, this area hosts one of the main nursery for the European hake Merluccius merluccius within the Northern and Central Adriatic Sea ((GFCM 2021)-[https://www.fao.org/gfcm/statutory-meetings/detail/en/c/1457591/]).  In the framework of an agreement with the Italian Ministry of Agriculture and Forestry (MIPAAF), CNR-IRBIM carries out since 2015, on board R/V Dallaporta, an autumn trawl survey in the western side of the Pomo Pits area; the survey aims to evaluate the effects of the management measures enforced in the area on the most commercially and ecologically important species (ScamPo survey; Martinelli et al. 2021). Furthremore, to understand possible effects of environmental changes on the species abundance and distribution, before or after each trawl haul, CTD (Conductivity Temperature Depth) data are collected with a SeaBird Electronic SBE 911plus (years 2015-2019) and SeaBird Electronic SBE 19plusV2 (years 2020 and 2021). The multi-parameter probes are also equipped with a SBE43 dissolved oxygen (concentration and saturation) sensor. A SBE 5T pump ensures a constant flow over time inside the sensors. The dataset here presented contains 61 CTD and Oxygen averaged profiles (0.5 db pressure interval) collected in autumn (from 2015 to 2021) within the Pomo Pits and in the surrounding area by means of multi parametric probes.  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].

CTD data collected during the iMAR 2021/Eurofleets+ research cruise in Mid Atlantic Ridge (Azores EEZ)

This dataset was produced during the iMAR cruise “The Integrated assessment of the distribution of Vulnerable Marine Ecosystem along the Mid-Atlantic Ridge (MAR) in the Azores region”, that took place aboard the Research Vessel Pelagia of the Royal Netherlands Institute for Sea Research between May 18th  and June 2nd 2021. The iMAR cruise aimed to evaluate the role of the MAR in shaping latitudinal and trans-Atlantic patterns in deep-sea biogeography, connectivity and assemblages of deep-sea megafauna. This expedition was funded by the SEA OCEANS program of Eurofleets+ and the H2020 European project iAtlantic, and was led by the University of the Azores (Portugal) in collaboration with the Hydrographic Institute and University of Porto (Portugal), the University of Aarhus (Denmark), the National Oceanography Center (United Kingdom), GEOMAR (Germany), the University Museum of Bergen (Norway), the PP Shirshov Institute of Oceanology (Russia), and the University of Vale do Itajaí (Brazil).   Vertical CTD/Rosette profiles were conducted with the CTD Seabird SBE 32 at 19 stations to measure physical and chemical seawater properties that characterize the dominant water masses described for the North MAR region of the Azores (Table 1). The “.CNV” files of fully processed data contain data of twenty-two parameters interpolated at 1-meter bins, (Table 2), mainly in the North portion of the MAR in the Exclusive Economic Zone around the Azores.

Sedimentological and palynological records since 8.5 ka BP along a proximal-distal gradient on the northern Bay of Biscay (NW Europe)

New results acquired in south-Brittany (MD08-3204 CQ core: Bay of Quiberon and VK03-58bis core: south Glénan islands) allow depicting Holocene paleoenvironmental changes from 8.5 ka BP to present through a multi-proxy dataset including sedimentological and palynological data. First, grain-size analyses and AMS-14C dates highlight a common sedimentary history for both study cores. The relative sea level (RSL) slowdown was accompanied by a significant drop of the sedimentation rates between ca. 8.3 and 5.7 ka BP, after being relatively higher at the onset of the Holocene. This interval led to the establishment of a shell-condensed level, identified in core VK03-58bis by the “Turritella layer” and interpreted as a marker for the maximum flooding surface. Palynological data (pollen grains and dinoflagellate cyst assemblages) acquired in core MD08-3204 CQ argue for an amplification of the fluvial influence since 5.7 ka BP; the establishment of the highstand system tract (i.e., mixed marine and fluviatile influences on the platform) then accompanying the slowdown of the RSL rise-rates. On the shelf, the amplification of Anthropogenic Pollen Indicators (API) is then better detected since 4.2 ka BP, not only due to human impact increase but also due to a stronger fluvial influence on the shelf during the Late Holocene. Palynological data, recorded on the 8.5–8.3 ka BP interval along an inshore-offshore gradient, also demonstrate the complexity of the palynological signal such as i) the fluvial influence that promotes some pollinic taxa (i.e., Corylus, Alnus) from proximal areas and ii) the macro-regionalization of palynomorph sources in distal cores. In addition, the comparison of palynological tracers, including API, over the last 7 kyrs, with south-Brittany coastal and mid-shelf sites subjected to northern vs. southern Loire catchment areas, allowed discussing a major hydro-climatic effect on the reconstructed palynological signals. Strengthened subpolar gyre dynamics (SPG), combined with recurrent positive North Atlantic Oscillation (NAO) configurations, appear responsible for increased winter precipitations and fluvial discharges over northern Europe, such as in Brittany. Conversely, weakened SPG intervals, associated with negative NAO-like modes, are characterized by intensified winter fluvial discharges over southern Europe. Interestingly, we record, at an infra-orbital timescale, major peaks of API during periods of strengthened (/weakened) SPG dynamics in sites subjects to Brittany watersheds (/Loire watersheds) inputs.

Thermistor chain temperature data from the EMSO-Azores observatory, 2020-2021

This dataset contains temperature data acquired with a 70 m long thermistor chain (50 m equipped with sensors, 20 m of cable to the monitoring station), deployed on the EMSO-Azores observatory from September 2020 to May 2021. Each thermometer is separated by 50 cm for a total of 100 temperature points. Data consist in 70 963 measurements acquired every 15 minutes. The chain is connected to the SEAMON East environmental monitoring node and measures temperatures on different faunal assemblages and substratum on the active Tour Eiffel edifice at 1695 m depth. The raw file contains all data acquired by the sensors. The corrected file was processed to remove outliers that included values below background seawater temperature (4°C), values above 30°C that corresponded to simultaneous periods of high/homogeneous temperature values recorded on all sensors. Unique outliers were then removed after screening of the graph. If extreme values lasted at least three consecutive step, they were kept. Removed values were replaced by NAs. Location of the Eiffel Tower edifice : N 37°17.33 - W 32° 16.53

TEMPO (1989-1993) Tyrrhenian eddy multi-platform observations (Western Mediterranean): hydrological data set of the cruises TEMPO-3 (fall 1991), TEMPO-4 (spring 1992), TEMPO-5 (spring 1993)

The principal aim of the Tyrrhenian Eddy Multi-Platform Observations (TEMPO) experiment  (1989-1993) was to study the signature of a mesoscale oceanographic eddy in the north Tyrrhenian Sea, between Italy, Corsica and Sardinia, using space-borne and airborne remote sensing and ship-based measuring techniques, but an effort was made to extend the observations in the southern part of the Tyrrhenian sea and throughout the water column.  The data contained in this dataset concerns the cruises TEMPO-3 (from 25 October to 8 November 1991, 44 stations), TEMPO-4 (from 23 April to 4 May 1992, 41 stations), and TEMPO-5 (from 8 to 13 March 1993, 71 stations). CTD profiles were collected using a Neil-Brown MK III CTD probe with a sampling time of 33 ms and a CTD fall speed of about 1 m/s. The temperature, conductivity and pressure sensors were calibrated at the SACLANT Centre in La Spezia before the cruise and again checked after its conclusion. Water samples were collected for the on-board calibration of the probe values. The final accuracies for the temperature and salinity were0.005 °C and 0.005, respectively. Successively the data were interpolated over 1 dbar interval. The data set is provided per cruise as ODV Spreadsheet files in TXT format, containing: Cruise name Station number Type of acquisition (here C) Date in mon/day/yr and Time in hh:mm:ss Coordinates in Longitude [degrees_east] and Latitude [degrees_north] Bottom depth [m] Depth [m] Temperature_IPTS-68 [deg C] Conductivity [S/m] Temperature_ITS-90 [deg C] Salinity_PSS-78 (Practical Salinity) Dissolved Oxygen [ml/l]
