Collection database of the Natural History Museum Rotterdam (marine part)

The collection of the Natural History Museum Rotterdam is, compared to other Dutch Natural History Museums, of medium size and holds many hundreds of thousands of specimens. A selection of the marine specimens has been made to be incorporated into EurOBIS.
The collection of the Natural History Museum Rotterdam is, compared to other Dutch Natural History Museums, of medium size and holds many hundreds of thousands of specimens. An exact count is hardly possible. The figures below relate to lots (individual specimens in most groups to samples including many individuals in others such as molluscs and foraminifers). 

A sample of molluscs f.i. may hold a large number of specimens collected on the same day at the same location. The size of particular parts of the collection also varies strongly: several thousands of Foraminifers are stored in a small cabinet, as the skeleton of a sperm whale fills an entire hall. Only a minor part of the collection (< 5%) is on exhibit in the permanent expositions 'wereldNatuur' and 'Het van Deinse Kabinet' or can be found in the public galleries of the Museum. 

The majority of the material contains data on specific name, finder, location and collecting date. These are important criteria when samples are stored in a scientific collection. It enables specialists to use the collection for further research regarding taxonomy, anatomy or biogeography.
Collection Aves (bird skeletons) SMF

The Aves (bird skeletons) collection is part of the SeSAM collections of Senckenberg which combines all collections held at the Senckenberg Natutal History Museum of Frankfurt. This collection contains bird skeletons from all over the world.
The ornithological collections at Senckenberg include about 90000 bird skins, 994 mounted specimens in the exhibition, about 11500 skeletons, 4000 spirit specimens, and 5050 egg clutches.  About 75% of the known bird species are represented. The geographic focus is on Central Europe, Northern Africa, and South America.  Concerning the number of specimens, it is the second largest ornithological collection in Germany.

The major part of the collection is not directly accessible for the public, but is used by scientists from all over the world, especially those studying the present and past geographic distribution of avian species. The hummingbird collection is of outstanding size and taxonomic completeness. The collection of bird skeletons is among the largest and most complete in Europe.

Whereas most birds have been killed for collection purposes in earlier centuries, new entries of the collection stem almost exclusively from accidental finds of dead specimens, from bird parks and zoological gardens, as well as from exchange with other institutes.
Red-necked Phalarope annual monitoring 1972-2010

This dataset was compiled to monitor the population and productivity of red-necked phalaropes in the UK.
Red-necked Phalaropes are diminutive waders with a small and fluctuating UK population. Monitoring has taken place on an ad-hoc basis since 1972 with an increase in coverage of the western isles in recent years. This dataset contains all records from this monitoring along with productivity data.Breeding data were collected in most years through the RBBP and local staff of both SNH (formerly NCC) and the RSPB. From 1992 onwards visits to find nest sites on Shetland were more frequent and included colour-ringing of young.The likelihood that phalaropes were breeding is grouped into three categories:Confirmed - by presence of a nest, sighting of pre-fledged chicks or males displaying/acting as if with youngProbable - if males present on a known/likely breeding site for 7 or more days and were associated with a female for all or part of that timePossible - if a pair or male were reported at a known/likely breeding site for 7 days or lessRecords are given here at 100m resolution, which represents the centroid of the site. Where the exact site is unknown, 1km or 10km resolution grid references are used.These data have been gathered by trained field-workers and the data are of a high quality. These data have been mapped and checked for sensitivities and typographical/geographical errors.
Temporal patterns in density and feeding ecology of Asterropteryx semipunctatus and Gnatholepis sp.1 in Gazy Bay (Kenya) in 1995

Temporal abundance data and stomach analysis for two gobies, Asterropteryx semipunctatus and Gnatholepis sp.1, caught in Gazi Bay between July and October 1995. The data were digitized by VLIZ from the original report: Ndede, R.O. (1998). Temporal patterns in the density and feeding ecology of gobies, Asterropteryx semipunctatus and Gnatholepis sp.1 in East African mangrove ecosystem (Gazi Bay, Kenya). MSc Thesis. KUL: Brussel. VIII, 97 pp.
To understand the 24 hrs (temporal) pattern in the density distribution and the consumption of prey items (food) for Asterropteryx semipunctatus and Gnatholepis sp.1, an investigation was carried out in the sub-tidal Western creek of Gazi Bay (Kenya) between July and October 1995. In order to investigate a semi-lunar pattern, ten twenty four hour cycles were sampled at consecutive spring and neap tides. A total of 480 (10 sampling x 12 sampling times x 4 locations) cases were collected. Two hours samplings consisted of 4 hauls with duration of 10 minutes and mean distance of 300m.
Early naturalists’ accounts (1818-1936) on the Adriatic Sea (Mediterranean Sea) fish fauna

Early naturalists’ accounts are an important source of past information on marine species and communities. These documents, particularly abundant in the 19th century because of the ascendancy of the Linnaean system, provide the earlier available systematic description of species that can be used to set a historical baseline of marine biodiversity in the Adriatic Sea. The dataset includes information on fish species reported in 29 books written by 24 naturalists published between 1818 and 1936.
Books were written in Italian, German or English, and translated into English. Information on invertebrates and mammals was not available in most books and thus it was not included in the dataset. Naturalists’ knowledge of fish fauna was primarily based on direct observations at fish markets and at ports, on interviews with fishermen, on literature and on the analysis of natural history museum collections. 255 fish species are described in terms of presence/absence, perceived-abundance, habitat, distribution, seasonality, reproduction, fishery, maximum length and maximum weight (4,027 records). In some documents, maximum length was expressed in Roman uncia (inch) or pes (foot), while maximum weight in Roman pound libra or ounce. The lengths were transformed in cm and approximated to the half millimetre according to the following: 1 Roman inch = 2.47 cm, 1 Roman foot = 29.65 cm. Weight was transformed in kg according to the following: 1 pound = 0.33 kg and 1 ounce = 0.027 kg. In the original documents, species were cited with their old scientific names (reported in the dataset under the field “SYNONYM”) that were updated according to the modern nomenclature referring to the World Register of Marine Species (WoRMS). The local vernacular name of each species is also reported in the dataset (under the field “VERNACULAR_ITALIAN_NAME”) as mentioned by the authors. For each book, the place where the author based his work is cited, when available (under the field “PLACE”).
Marine benthic dataset (version 1) commissioned by UKOOA

A comprehensive review of seabed environmental surveys has been commissioned by UKOOA to document and analyse data collected from offshore environmental surveys carried out on the behalf of UK North Sea offshore oil operators.
The purpose of these environmental surveys is to monitor the seabed in the vicinity of offshore operations with the aim of detecting environmental impact. It is estimated that some 520 seabed surveys were carried out between 1975 and 1998, covering work carried out by approximately 29 environmental monitoring contractors, government agencies and universities. 472 reports have been located, examined and listed in the database. The UKOOA seabed environmental review was carried out in three phases. Phase 1 consisted of the compilation of an inventory of surveys carried out in the UK sector. Phase 2 involved the production of database files containing detailed biological, chemical and locational data. Phase 3 examines the extent of contamination from offshore E and P activities and impacts on the biota, and will attempt to determine any large-scale trends over wider geographical areas. The database files were exported to the NBN gateway in October 2004 - note that a new version of the database is now available. This involved a fair amount of data cleaning due to the range of quality of the data that had been compiled. There were 203.945 records exported to the NBN gateway.

This copy of an original held by UKOOA (see link below). Some cleaning of the data was carried out and 37.247 records were not exported to the Gateway due to validation or data quality issues (Unknown species 9.860, Positional accuracy very vague 4.420, No Position 22.550, No site or date 417). It is possible that with additional work from a taxonomic specialist some of the unknown species may be able to be added, but many of these were actually records of debris, tomato pips etc.

Data on cetacean occurrence collected during the project “Identification and initial assessment of cetacean groupings in coastal waters of the north-western Black Sea, Ukrainian sector” funded by ACCOBAMS 2016-2017

The data contain information collected during the implementation of the ACCOBAMS Project “Identification and initial assessment of cetacean groupings in coastal waters of the north-western Black Sea, Ukrainian sector” 2016-2017 on the occurrence of the cetaceans in the north-western part of the Black Sea including photo identification surveys and linear-transect surveys of density and abundance.
ILVO epifauna en demersale visdata: epifauna en demersale vismonitoring op het Belgisch deel van de Noordzee sinds 1979

Densiteit, soortenrijkdom en diversiteit van epifauna en demersale vis wordt  op het Belgisch deel van de Noordzee opgevolgd sinds 1979.
Het epibenthos en de demersale vis worden bemonsterd op een aantal stations verspreid over het Belgisch Continentaal Plat.

Staalnames gebeuren met een 8m boomkor en een fijnmazig garnalennet (22mm in de kuil en een bollenpees), gedurende een half uur durende vissleep,
gevaren aan 3.5 knopen. Een dergelijk net heeft het voordeel dat het minder schadelijk is voor
het bodemecosysteem dan wanneer met kettingmatten zou gewerkt worden. Toch is het efficiënt
voor het bemonsteren van epibenthische organismen en de meeste demersale vissoorten. Enkel
organismen die zich 'vasthechten' aan de bodem zoals tong, semipelagische soorten zoals
haring en dunne vissoorten zoals zandspiering worden iets minder efficiënt gevangen.

Het materiaal wordt direct gesorteerd, al dan niet m.b.v. een spoel- en sorteermachine, aan boord
en/of in het labo gedetermineerd, gemeten en geteld. De gebruikte parameters zijn densiteit,
soortenrijkdom en diversiteit.
LifeWatch observatory data: phytoplankton observations by FlowCam imaging in the Belgian Part of the North Sea

In the framework of the Lifewatch marine observatory a number of fixed stations in the Belgian Part of the North Sea (BPNS) are visited on a monthly or seasonal basis using RV Simon Stevin. A grid of nine stations covers the coastal zone and are sampled monthly. Eight additional stations, located further at sea, are sampled on a seasonal basis. Samples are taken using a 55µm mesh size Apstein net and fixed in Lugol's iodine solution. In the lab, the samples are processed using a VS-4 FlowCAM model at 4X magnification, size range imaged is 55-300µm. The identification of the image data is done with the use of a classifier and followed by a manual validation step.  Since May 2017, this dataset provides micro- and phytoplankton observations, mainly covering diatoms, dinoflagellates and cilliates, for the Belgian Part of the North Sea (BPNS).
Taxonomic disclaimer: The blooms of Rhizosolenia and Bellerochea were flagged due to their extreme nature, which can lead to biased density estimates during these bloom periods. These taxa, when blooming outside their typical seasons, can skew results, although abundances remain unaffected. Additionally, the sampling methods, such as net sampling and prefilters, inherently under-sample taxa near the 300µm threshold, further contributing to the need for flagging these extreme events. It especially relates to samples 2021 07 120 (Rhizosolenia, Long (chained) diatom) and 2022 08 130 (Bellerochea en Rhizosolenia)
Temporal evolution of zooplankton from 1898-1917 and 1966 onwards in the Northwestern Mediterranean Sea

The Observatoire of Villefranche sur Mer supports the daily sampling of zooplankton from 1898-1917 and 1966 onwards at a time series station located at the entrancy of the Bay of Villefranche sur Mer. Samples were collected by a vertical tow from bottom to surface (75-0 m), using a Juday-Bogorov net and Regent net. The sampling site is located at the mouth of the Bay over a bathymetry of 80m and is thus open to the Ligurian Sea. Zooplankton abundance was counted by specialist at OOV under microscopes.
The different equipment which was used is the following: Regent net: 680µm of mesh, opening: 1m, length: 4m, opening: 0.785m²; Regent net: 700µm of mesh, opening 1m, length: 4m; Juday-Bogorov net: 380 µm of mesh, opening: 0.50, length: 1.80m; WP2: 220µm of mesh, opening: 0.25m².
Method step description: For the siphonophores, since 1993, all data are transformed from a Regent Net to a Juday-Bogorov net with a coefficient *6 as described in original publication.
