Atlantic Meridional Transect cruise AMT16 Coccolithophore composition - light microscopy (CTD bottles)

This dataset contains coccolithophore abundance data from CTD bottles collected during the AMT16 cruise in the Atlantic between Cape Town, South Africa and the United Kingdom in May-June 2005. Bottle samples were collected from 6 light depths from the pre-dawn (between approximately 03:00 - 04:30 local time) and noon CTD casts. Microscope enumeration of coccolithophores and coccoliths was performed by filtering a 100 - 500 millilitre water sample through a Millipore HA filter, which was then rinsed with borate buffer, and frozen in a petri dish until counted. The filter was placed on a glass microscope slide, and a 60 degrees Celsius Canada Balsam was placed on top of the filter, followed by a cover slip. The clarified filter was examined for birefringent and plated coccolithophore counts, with an Olympus BH2 microscope equipped with polarization optics. For statistical reasons, 200 coccoliths or cells were counted from each sample, when available. These data were collected for the Atlantic Meridional Transect (AMT) project by scientists from the Bigelow Laboratory for Ocean Sciences.
Continuous Plankton Recorder Dataset (NOAA) - Zooplankton

Continuous Zooplankton Recorder Survey by NOAA in the Northwest Atlantic, the Gulf of Maine and the Mid Atlantic Bight.

ARMS-MBON data on long-term monitoring of hard-bottom communities: 18S results from 2020-2022

ARMS-MBON is a network of more than 25 partners who deploy Autonomous Reef Monitoring Structures (ARMS) settlement units in the vicinity of marine stations and Long-term Ecological Research sites in European coastal waters and Ant/arctica. After a few months the units are brought up, and visual, photographic, and genetic assessments are made of the lifeforms that settled on them. The collected data are published (see the related datasets and GitHub links listed in this record) and the omics data analysed. In this record we include the outputs of our analysis of the 18S data from the 2020-2022 campaign. The analysis used the PEMA bioinformatics software, and the resulting taxonomics inventory has been turned into DwC format. In addition, all the PEMA inputs and outputs can be found on the ARMS-MBON GitHub site (see links in this record), and the subset of the sampling data to which these 18S results are linked can also be found on the ARMS-MBON GitHub site.
Seasearch Crawfish, Palinurus elephas, Surveys

This survey was carried out to gather information regarding the numbers and distribution of Crawfish throughout Britain and Ireland. The dataset consists of records of sightings of Palinurus elephas by scuba divers.
This dataset consists of records of sightings of Palinurus elephas or Crawfish by scuba divers. The welsh records from 1969 - 2009 were obtained from logbook entries made by divers. Data from 2009 onwards is from entries made by divers on the Seasearch online Crawfish observation site. It should be noted that other observations of crawfish made during wider Seasearch surveys are included in the Seasearch Marine Surveys database and are not duplicated here. Data has been provided by volunteer divers and does not attempt to provide a comprehensive picture of distribution of crawfish either spatially or temporarily. There can be high confidence in the accuracy of the records made as crawfish is an easily identified species, however, absence of records will in part be due to sporadic nature of recording. Further information available from the Seasearch Coordinator (Chris Wood).
Citizen Science based jellyfish observations along the Israeli Mediterranean coast in 2011-2024

Jellyfish observations (Citizen Science Data) are collected from the Israeli Mediterranean coast and sea since June 2011 via a webapp (www.meduzot.co.il). Observations are validated by experts in a two-tier process, once daily and again semi-annually. This data is used to alert the public to incoming swarms and helps us increase our knowledge of their behavior, ecology, phenology (e.g. Edelist et al. 2022; Levy et al. 2024), and taxonomy (Edelist et al. 2019). The project also educates and disseminates information about jellyfish sting prevention and treatment (Edelist et al. 2023). This data is also stored in the EU Iliad Project Ocean Information Model.
Norman and Florence Hammond records. Seawatch and coastal survey records

This dataset comprises a collection of records of marine organisms, collated by Norman and Florence Hammond before 2005.
To represent the marine flora and fauna of the Solway and the wider Irish Sea more completely, Norman and Florence Hammond collated a collection of records of marine organisms, based on sightings from organised surveys, media reports and casual observations.

The geographical coverage comprises the Northern Irish Sea and the Solway coastal areas, stretching from Stranraer to North Wales and around the Isle of Man. 

The dataset has been verified, as far as is practical, by local wildlife experts and organisations. The work was part of an active verification project, the report of which is available on request. However, a level of uncertainty around the dataset remains, and errors in geography almost certainly exist. Any queries should be directed in the first place to the Manager of the Cumbria Biodiversity Data Centre.
Atlantic Meridional Transect cruise AMT12 - Microzooplankton abundance and biomass (optical microscopy) (CTD bottles)

This dataset contains microzooplankton abundance and biomass data from CTD bottle samples collected during the AMT12 cruise in the Atlantic between Port Stanley, Falkland Islands, and Grimsby, United Kingdom, in May-June 2003. The data contribute to the AMT project and were collected by scientists from the Plymouth Marine Laboratory.
Yorkshire Naturalists Union Marine and Coastal Section Records

This dataset contains species records gathered during field meetings of the Yorkshire Naturalists Union Marine and Coastal Section since 2011, as well as records gathered during a marine life identification course in 2010.
To improve our understanding of the distribution of marine and coastal species in Yorkshire, species records were gathered during field meetings of the Yorkshire Naturalists Union Marine and Coastal Section since 2011, as well as during a marine life identification course in 2010. All intertidal surveys have been carried out by volunteers. The dataset includes records collected by members of the public during the Scarborough Bioblitz in June 2011, all of which were verified by experienced recorders. Records from the Scarborough Bioblitz include specimens collected by a fishing vessel and by divers. This dataset does not contain any mollusc records, as these have been provided to the Conchological Society. Since this dataset consists of records made by volunteer recorders during YNU field meetings and ad hoc records sent in by YNU members independently, it should not be regarded as having comprehensive geographic or taxonomic coverage. Where possible, records are determined in situ by experienced recorders within the YNU, and in some cases photographs and specimens have been sent to experts for verification.
SmartBuoy Marine Observational Network - UK Waters Phytoplankton Data 2001-2017

This dataset consists of analysed phytoplankton data from the years 2001-2017 inclusive collected in UK waters from the SmartBuoy moorings at Celtic Deep, Dowsing, Gabbard/West Gabbard/WestGabbard2, Warp and Liverpool Bay using WMS and EDU automated water samplers. SmartBuoys consist of a 4 meter tall stainless steel frame with a fibreglass toroid for buoyancy. Instruments are attached at a nominal 1 meter depth to the frame. The water samplers collect into pre-spiked bags containing acidified Lugols Iodine on a pre-determined cycle over the course of a deployment. Following recovery these samples were analysed for a full community of phytoplankton species using the Utermohl method on high-power inverted microscopes. Phytoplankton cell counts are abundance values reported in Cells per Litre.

Atlantic Meridional Transect cruise AMT15 Coccolithophore composition - light microscopy (surface underway)

This dataset contains coccolithophore abundance data from surface underway samples collected during the AMT15 cruise in the Atlantic between the United Kingdom and Cape Town, South Africa in September-October 2004. Surface samples were collected approximately every 3 to 6 hours from the non-toxic water supply. Microscope enumeration of coccolithophores and coccoliths was performed by filtering a 100 - 500 millilitre water sample through a Millipore HA filter, which was then rinsed with borate buffer, and frozen in a petri dish until counted. The filter was placed on a glass microscope slide, and a 60 degrees Celsius Canada Balsam was placed on top of the filter, followed by a cover slip. The clarified filter was examined for birefringent and plated coccolithophore counts, with an Olympus BH2 microscope equipped with polarisation optics. For statistical reasons, 200 coccoliths or cells were counted from each sample, when available. These data were collected for the Atlantic Meridional Transect (AMT) project by scientists from the Bigelow Laboratory for Ocean Sciences.
2015_DIJLE - Acoustic telemetry data for five fish species in the Dijle river (Belgium)

This is an acoustic telemetry dataset published by the Research Institute for Nature and Forest (INBO). It contains animal (fish) tracking data collected by the Permanent Belgian Acoustic Receiver Network  (https://lifewatch.be/en/fish-acoustic-receiver-network) for the project/study 2015_dijle, using VEMCO tags (V7, V13) and receivers (VR2AR, VR2W). In total 26 adult individuals of five local wild fish species (Anguilla anguilla, Cyprinus carpio, Platichthys flesus, Rutilus rutilus, Silurus glanis) were captured, tagged and released in 2015, to study the effect of a specific barrier on their upstream/downstream migration in the Dijle basin.
Fish migrating from the sea to the Dijle river (or vice versa) are obstructed by a weir in the city of Mechelen which is designed to prevent tides from entering further inland. To mitigate this problem, fish-friendly weir management was implemented, the effect of which was measured in this study with acoustic telemetry. In 2015, 26 individuals of five fish species - European eel (Anguilla anguilla), common carp (Cyprinus carpio), flounder (Platichthys flesus), roach (Rutilus rutilus) and wels catfish (Silurus glanis) - were captured, tagged and tracked in the areas up- and downstream of the weir. 3 wels catfish tagged for the 2014_demer study were also detected. Results of the evaluated weir passages by fish showed that 21 of 29 fish were able to pass the weir at specific hydrological conditions and weir management options. The number of passages differed between species, but happened always in the periods that higher passage could be expected following their lifestyle. The study indicates the importance and benefits of a fish-friendly weir management.

This dataset was collected using infrastructure provided by VLIZ and INBO funded by the Research Foundation - Flanders (FWO) as part of the Belgian contribution to LifeWatch. The study was commissioned by the Vlaamse Waterweg NV. Data were exported from the European Tracking Network data portal (http://www.lifewatch.be/etn) developed by VLIZ using the ETN R package (https://inbo.github.io/etn/) developed by INBO. Field definitions can be found at https://inbo.github.io/etn/articles/etn_fields.html.
RSMP Baseline Dataset

This dataset was compiled for the Regional Seabed Monitoring Plan (RSMP) baseline assessment reported in Cooper - Barry (2017).
The dataset comprises of 33,198 macrofaunal samples (83% with associated data on sediment particle size composition) covering large parts of the UK continental shelf. Whilst most samples come from existing datasets, also included are 2,500 new samples collected specifically for the purpose of this study. These new samples were collected during 2014-2016 from the main English aggregate dredging regions (Humber, Anglian, Thames, Eastern English Channel and South Coast) and at four individual, isolated extraction sites where the RSMP methodology is also being adopted (e.g. Area 457, North-West dredging region; Area 392, North-West dredging region; Area 376, Bristol Channel dredging region; Goodwin Sands, English Channel).
This work was funded by the aggregates industry, and carried out by contractors on their behalf. Samples were collected in accordance with a detailed protocols document which included control measures to ensure the quality of faunal and sediment sample processing. Additional samples were acquired to fill in gaps in spatial coverage and to provide a contemporary baseline for sediment composition.

Sources of existing data include both government and industry, with contributions from the marine aggregate dredging, offshore wind, oil and gas, nuclear and port and harbour sectors. Samples have been collected over a period of 48 years from 1969 to 2016, although the vast majority (96%) were acquired since 2000. Samples have been collected during every month of the year, although there is a clear peak during summer months when weather conditions are generally more favourable for fieldwork.
Cover of Intertidal Macroalgae along the N and NW Coast of the Iberian Peninsula in 2011

A standardized sampling methodology was carried out in 21 sites along the N and NW Iberian Peninsula. Field surveys were carried out during the low spring tides in April 2011. At each site, three transects perpendicular to the coast were selected. A stratified and systematic sampling procedure was carried out, dividing each transect into four areas: lower intertidal, middle intertidal, upper intertidal and supralittoral. The sampling stations were distributed at equal distances, three in the lower and middle intertidal and two in the upper intertidal and supralittoral. The sampling unit was standardized using a 50 x 50 cm grid.
Algae were identified to the species level in situ or assigned to higher taxonomic categories when species identification was not possible. The taxa cover was obtained by photographic analysis. For this purpose, at least one photo of the grid was taken at each station. Then, the photographs were georeferenced and adjusted to the actual size of the field of view in ARCGIS. Macroalgae taxa were identified and outlined to create polygons whose areas were measured and recorded.
BfG - Estuary Monitoring Programme Macrozoobenhos

This dataset contains macrozoobenthos data from the BfG - Estuary Monitoring Programme.
The programme was designed and installed by Stefan Nehring in 1995 with the aim to get more data about macrozoobenthos in German North Sea estuaries. It was installed as a long-term monitoring, however, without any statuatory regulation. Since 1995 the data are integrated in the national "Bund Länder Messprogramm (BLMP)".
Brachiopodacollectie van het Koninklijk Belgisch Instituut voor Natuurwetenschappen

Atlantic Meridional Transect cruise AMT13 Microzooplankton (nauplii and copepodites) and mesozooplankton taxonomy and abundance (Net Hauls)

This dataset contains microzooplankton (nauplii and copepodites) and mesozooplankton taxonomy and abundance, ingestion rates, and nauplii gut evacuation rates data from net haul samples collected during the AMT13 cruise in the Atlantic between the UK and the Falkland Islands, in September-October 2003. To estimate zooplankton abundance, vertical net samples were taken from 200 m to the surface with a WP-2 net, equipped with filtering cod-ends, during night stations (between 00:30 and 4:30 h local time). The pore mesh net was 53 µm and 30 µm for the filtering cod-ends. Tows were performed at low speed (0.5 m s -1). The net was not equipped with a flow-meter, so to calculate the volume filtered the diameter of the net (27 cm) was used to calculate the volume filtered (11.45 m 3 ) for each cast. Samples were screened through 1000, 500, 200 and 30 µm meshes, put in 250 ml bottles and fixed with 4% buffered formaldehyde. In the laboratory, abundance of main taxonomic groups of metazooplankton was determined under a stereomicroscope. Ingestion rates were calculated using the gut fluorescence method (Mackas and Bohrer, 1976). The data were collected by scientists from the University of Oviedo Department of Organism and Systems Biology.

The CPR Survey

The SAHFOS CPR survey is the longest and most geographically extensive marine biological survey in the world. The CPR survey has been in operation in the North Sea and North Atlantic since 1946 and has systematically sampled up to 500 planktonic taxa from the major regions of the North Atlantic at a monthly resolution. This dataset contains also CPR surveys in the Pacific and the South Atlantic.
The Continuous Plankton Recorder (CPR) survey has been operating in the North Atlantic and North Sea since 1946 and measures the abundance of approximately 450 phytoplankton and zooplankton taxa (Warner and Hays, 1994). The CPR is a high-speed plankton recorder that is towed behind ‘ships of opportunity’ through the surface layer of the ocean (~10 m depth). Water passes through the recorder, and plankton are filtered by a slow moving silk (mesh size 270 μm). A second layer of silk covers the first and both are reeled into a tank containing 4% formaldehyde. Upon returning to the laboratory, the silk on is unwound and cut into sections corresponding to 10 nautical miles and approximately 3 m3 of filtered sea water. The colour of each section of CPR silk is then evaluated and categorized according to four levels of ‘greenness’ (green, pale green, very pale green and no colour) using a standard colour chart; these numbers are given a numerical value as a measure of the ‘Phytoplankton Colour Index’. This is a semiquantitative measure of phytoplankton biomass; the silk gets its green colour from the chloroplasts of the filtered phytoplankton. Phytoplankton cells are then identified and recorded as either present or absent across 20 microscopic fields spanning each section of silk; CPR phytoplankton abundance is therefore a semiquantitative estimate (i.e. the species is recorded once per field independent of the number of cells in a field). However, the proportion of cells captured by the silk reflects the major changes in abundance, distribution, and community composition of the phytoplankton (Robinson, 1970), and is consistent and comparable over time. Zooplankton analysis then carried out in two stages with small (2 mm) zooplankton enumerated off-silk. The collection and analysis of CPR samples have been carried out using a consistent methodological approach since 1958, making the CPR survey the longest continuous dataset of its kind in the world (Edwards and Richardson, 2004).
Macrobenthos and Phytoplankton monitoring in the Belgian coastal zone in the context of the EU Water Framework Directive (WFD)

Phytoplankton biomonitoring of the Belgian continental zone performed in the light of the European Water Framework Directive (WFD). The aim of this project is to develop a standardized method for routine phytoplankton monitoring of the Belgian coastal zone, by comparing and developing the best available techniques concerning preservation, identification and enumeration of marine phytoplankton samples, with special attention to Phaeocystis.
