Invertebrates

This database contains information on the so far registered specimens in the invertebrate collection of the Swedish Museum of Natural History
The collections in the Department of Invertebrate Zoology comprise about 500.000 lots preserved in ethanol, dried or on microscope slides.

The oldest specimens were collected during the 18th century. A considerable part of the collections were acquired towards the end of the 19th century and in the early 1900s, when several expeditions, e.g. the Vega expedition and the Swedish South Polar expedition brought material to the museum.

At present, most new specimens are acquired as a result of on-going research projects at the department.

The type collection (specimens that were used for the description of new species and introduction of new scientific names) comprises about 7.000 lots.

Almost half of the collections in the Department of Invertebrate zoology are preserved in ethanol (70-80%) and kept in an underground storage. 

Animals with hard shells, tests or spicules etc., e.g. molluscs, corals and sponges, are also kept in the dry collection.

Many invertebrates are microscopic. Therefore a part of the collection is mounted on microscope slides, either as whole mounts or as serial sections.

The collections are being catalogued electronically since 1997 and since Aug 2004 the database is searchable via GBIF (Global Biodiversiy Information Facility).
Tunicates collection (IT) of the Muséum national d'Histoire naturelle (MNHN - Paris)

The database lists all the specimens or lots (9 000) of Tunicates housed in the Paris Museum. It is the largest or second largest tunicate collection in the World, based on the number of specimens and the number of types. All the specimens are identified to species. The collection is principally the result of the active research of two people (Claude Monniot - Francoise Monniot) over the course of forty years.

The median values ranges are derived from the following percentiles: 0-25%, 25-75%, 75-90%, >90%. Only "good data" are used, namely data with Quality Flag=1, 2, 6, Q (SeaDataNet Quality Flag schema). For water, only surface values are used (0-15 m), for sediment and biota data at all depths are used.
Phytoplankton data from the PHYCO cruise in the Strait of Dover in April 2017

The PHYCO cruise was devoted to the study of the phytoplankton spring bloom in the Eastern Channel-southern North Sea region, by combining in situ continuous recording at sub-surface waters and discrete sampling and profiling at fixed stations, collecting and analysing samples both in surface and at different depths.
The objective is to study the abundance, composition (functional groups, taxonomy) and physiological state of phytoplankton assemblages discriminated by in situ multi-spectral fluorometry, pulse shape-recording flow cytometry, image in flow analysis, Pulse Amplitude Fluorometry (PAM) and Fast Repetition Rate Fluorometry (FRRF). Besides, reference determination of phytoplankton species and pigmentary groups by microscopic observation and pigments analysis was carried out. This cruise is the first of a series of three cruises of the implementation of innovative semi-automated techniques for defining an automated observatory of phytoplankton and HABs, Joint Research Action Project #1 (JRAP#1) of the JERICO-NEXT project
Mackerel and horse mackerel eggs

The survey existed since 1968. It is carried out every 3 years in the north eastern Atlantic. The year after the Atlantic survey, a mackerel egg survey is conducted in the North Sea. The survey creates a basis for the stock assessment of Atlantic and North Sea mackerel and management plan for Atlantic horse mackerel. The historical MEGS data is expected to be uploaded in 2015-2016. The group responsible for the survey is WGMEGS.
The working group on mackerel and horse mackerel egg surveys (WGMEGS) coordinates the Mackerel and Horse Mackerel Egg Survey in the Northeast Atlantic and the Mackerel Egg Survey in the North Sea, both which are carried out triennially. Eggdata collected from both surveys provide an indices for the strength of the SSB of both the western and North Sea stocks of Atlantic mackerel (Scomber scombrus) and a relative abundance index of horse mackerel (Trachurus trachurus) spawning stocks in the Northeast Atlantic. The surveys are divided into 3 geogr aphical component areas, the western, southern and the North Sea. In the western area the mackerel egg survey has been running continuously on a triennial basis since 1977 and since 1992 has also sampled the southern spawning component. It typically takes place between February and July and aims to cover the entire spawning area from Cadiz in the south up as far as NW Scotland in the North and since 2010 up to the waters around the Faroe Islands and southeast of Iceland. The egg survey in the North Sea has been running since 1968. 

A comprehensive description of the survey protocols, analysis techniques together with the methods used for calculating the egg abundance estimates can be found in the WGMEGS survey manual which is contained within Annex 5 of the 2 012 WGMEGS
Use of EMODNET Biology Data for invasive species policies. What can we learn?

The use of ballast water is increasingly subjected to regulations because they are vectors for the spreading of invasive species. OSPAR and HELCOM have been working on a decision support tool and a harbour database to reduce unnecessary ballast water checks. In this analysis, we explore what EMODNET could offer to the efforts devoted to this decision support tool. This workflow demonstrates the use of the EMODnet Biology/EurOBIS database as a tool to check for false negatives in the harbour dataset. This is a workflow, rather than an end product. We hope that the workflow, documented at code level in this product, can be taken up and further extended by the authorities responsible for invasive species management.
Thermal affinities for European marine species

This data product shows how to derive, summarise and visualise thermal affinities for European marine species. The aim is to derive thermal affinities for all European marine species, by matching occurrence records from OBIS to gridded temperature products. These species-level thermal affinities are then used to produce assemblage-level averages on a 0.5º grid covering European seas, separately for major functional groups (e.g. benthos, zooplankton, fish). Finally these gridded assemblage-level averages are compared to current and projected future sea temperatures to identify areas of high climate vulnerability for each functional group.
This work is supported by EMODnet biology with additional support to TJW during development of these methods provided by the UK Marine Ecosystems Research Programme.
2010, GEMS, Zone 3 Dogger Bank Tranche A and Met Masts, Acoustic and Geophysical Survey

GEMS Survey Ltd. (GEMS) were contracted by Forewind Limited to undertake a bathymetric and geophysical survey of the Tranche A development area and two met mast locations (which were later revised) within the Dogger Bank Zone, in addition to a cable reconnaissance from Tranche A to the Yorkshire coastline.

This survey was carried out between 8 July 2010 and 26 December 2010.

The primary objectives of the survey were to produce sufficiently high resolution bathymetric and geophysical data and interpretations to allow regional interpretation for planning and modelling purposes; for met mast design to commence and to provide high quality data to inform further benthic and environmental surveys.

GEMS supplied interpreted datasets compatible with ESRI ArcGIS software.  The GIS data included bathymetry, sidescan sonar mosaics, seabed features,  sediments and obstructions.
Microplastic in sediment from Denmark 2012-2013

This study is a first attempt in Denmark
on assessing the presence of microplastics in our
open & coastal waters from Baltic to North Sea.
The occurrence and impact of microplastics have
in the Danish initial assessment for EU’s Marine
Strategy Framework Directive (MSFD)
been identified as a relevant indicator for
describing “Good Environmental Status” (GES)
for descriptor 10 on Marine Litter.
Microplastic particles in marine waters,
which consist of synthetic polymer materials,
origin mainly from secondary microplastics, i.e.
fragments of litter like solid waste, fishing gear, paint
flakes etc. from either sea- or land based sources.
Primary microplastics (engineered) are not expected to
be as common as secondary microplastics.
Microplastics can origin from both local sources and
from long-range transport with ocean or air currents.

Bathymetry_Constanta_2021

Bathymetry  surveys carried out in the frame of INTELMAR Nucleu Programme, funded by the Romanian National Authority for Scientific Research and Innovation (ANCSI), projects no. PN19260101 “Study the dynamics of natural processes and hydro-geo-morphological risk assessment and vulnerability of marine and coastal zone due to climate change and human pressures". Measurements were carried out in order to map the geo-morphological features and habitat mapping in shallow waters (up to 10/20 m depth, in the Constanta coastal area).
REMP project - Longhurst Provinces

The dataset represents the division of the world oceans into provinces as defined by Longhurst (1995; 1998; 2006). The division has been based on the prevailing role of physical forcing as a regulator of phytoplankton distribution. The dataset contains the initial static boundaries developed at the Bedford Institute of Oceanography, Canada. Note that the boundaries of these provinces are not fixed in time and space, but are dynamic and move under seasonal and interannual changes in physical forcing. At the first level of reduction, Longhurst recognised four principal biomes: the Polar biome, the Westerlies biome, the Trade winds biome, and the Coastal biome. These four biomes are recognised in every major ocean basin. At the next level of reduction, the ocean basins are divided into provinces, roughly ten for each basin. These regions provide a template for data analysis or for making parameter assignments on a global scale. 
This data set has been used as one of the data inputs in the Atlantic REMP project. This project, funded by the European Union, worked together with stakeholders to produce a draft Regional Environmental Management Plan (REMP) for the Area in the North Atlantic, with a focus on the polymetallic sulphide deposits of the Mid-Atlantic Ridge which are of interest for deep-sea mining. There was close collaboration with the International Seabed Authority (ISA) and a consortium of scientific organisations. Marine data from multiple data services underpinned the environmental management plan development. A selection of the data sets is included in EMODnet Ingestion for wider distribution.
EMODnet Biology

The EMODnet Biology products include a set of gridded map layers showing the average abundance of marine species for different time windows (seasonal, annual) using geospatial modelling. The spatial modelling tool used to calculate the gridded abundance maps is based on DIVA. DIVA (Data-Interpolating Variational Analysis) is a tool to create gridded data sets from discrete point measurements of the ocean. For the representation of time dynamics, it was decided to produce gridded maps for sliding time windows, e.g. combining one or more years  in one gridded map, so that relatively smooth animated GIF presentations can be produced that show the essential change over time. EMODnet Biology’s data products include the Operational Ocean Products and Services (OOPS), harvested by ICES.
EMODnet Bathymetry - Quality index version 2020

EMODnet bathymetry is composed of a multitude of datasets from a multitude of data providers. Users of the resulting grid and associated datasets need to be able to evaluate at the grid node level the quality of the bathymetric data and product they will be using. 
For this EMODnet Bathymetry has introduced a Quality index (QI).  The QI is available as a WFS service providing vector data and as WMS providing the QI as an image service. 
The aim of the quality index is to: 
•	help data users to evaluate quickly the dataset they are about to request, 
•	indicate to the EMODnet Basin coordinators what are the limitations of the dataset they are about to merge while building the EMODnet DTM and to 
•	be used as the basis of the evaluation of the quality of the EMODnet DTM.
