Vulnerable Marine Ecosystems

The dataset is comprised of; 1) 'VME habitats' which are records for which there is unequivocal evidence for a VME, e.g. ROV observations of a coral reef, 2) VME indicators which are records that suggest the presence of a VME with varying degrees of uncertainty. For VME indicators a weighting system of vulnerability and uncertainty is provided as part of the database to aid interpretation.
ICES VME Database - A central portal (http://vme.ices.dk) for data on the distribution and abundance of Vulnerable Marine Ecosystems (VMEs), (and organisms considered to be indicators of VMEs) across the North Atlantic has been set up by the Joint ICES/NAFO Working Group on Deep-water Ecology (WGDEC). Criteria used to select habitats and indicators for inclusion in the database were those described in the FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas (FAO, 2009). The VME database may be used for many purposes; ICES will use it when providing scientifically -robust advice on the distribution of VMEs and recommending possible management solutions such as bottom fishing closures within NEAFC (North East Atlantic Fisheries Commission) waters to protect VMEs.
Phytoplankton in the South Adriatic Sea (ADREX Experiment) 2014

Phytoplankton collected in the South Adriatic Sea during ADREX Experiment in February 2014. The ADREX experiment, as part of EU Project PERSEUS (http://www.perseus-net.eu), focuses on the investigation of the role of the Adriatic-Ionian system in transmitting the human-made pressures in the eastern Mediterranean through the Adriatic Dense Water (AdDW) formation and spreading.
Sampling along the water column was performed with Niskin bottles associated to a CTD profiler. At each station, several discrete depths were sampled, according to station depth and hydrological vertical profiles.


Samples were fixed with Ca(HCO3)2-buffered formaldehyde (0.8% final concentration) and cell abundance and species composition of phytoplankton were estimated according to Utermöhl’s method (1958), using an inverted microscope equipped with phase contrast, at 200-320-400x final magnifications.
Gelatinous macrozooplankton abundance and biomass in inshore and deep waters of the Northwestern Black Sea

The dataset contains abundance and biomass data of four species of gelatinous zooplankton (Mnemiopsis leidyi, Beroe ovata, Aurelia aurita, Pleurobrachia pileus) obtained in October 2005 and October - November 2010 (32 stations in October 2005 and 98 stations in October - November 2010) in the Northwestern Black Sea.
Harant H. 1939. The fishery grounds near Alexandria. Ascidiacea (Cartes 1-5). Notes et Memoirs No 28

This is a historical dataset that was published in 1939 by H. Harant and concerns of the faunistic report on the Ascidiacea collected during the floristical and faunistical survey of Adolf Steuer on the coasts near Alexandria mainly with the vessel "El Hoot".
This dataset contains occurrence data of Ascidiacea in the coasts of Alexandria, Egypt. Temporal coverage for this dataset is not described in the historical paper but only in the preliminary report of the expedition. Thus, it is assumed that the sample collection was done in the autumn of 1933 (beggining from the end of August to end of November).The digitization of this dataset was done by LifewatchGreece team.

Ascidiacea were found in about 30 sampling stations near Alexandria, Egypt, eastern Mediterranean.

This dataset is only a part of a large faunistical expedition (http://ipt.medobis.eu/resource?r=egyptexpeditionpreliminaryrepor) that took place in the coasts near Alexandria. The samples were collected by A. Steuer. For bottom samples almost exclusively a dredge with 20x70 cm opening was used. A single catch was made in a depth of 20 m with a large otter trawl in the eastern part of the Bay of Abukir. In general, the motor-launch of the Marine Laboratory "El Hoot" was used for dredging and a rowing boat in shallow water. All excursions were one-day trips. After the expedition, taxonomic identification of the samples was done by specialists. The results of this expedition were published in separate for each taxonomic group volumes. Thus, sampling methods were described in a preliminary report by A. Steuer. Ascidian species were identified by H. Harant.
Gelatinous macrozooplankton abundance and biomass in Sevastopol Bay and inshore waters off the Crimean Coasts of the Black Sea

Incidental sightings of marine mammals

Data on incidental sightings of cetaceans reported to the Institute of Marine Research by letter or telephone, as well as information from newspapers, have been collected since 1967. From the late 1970s, data have also been obtained from research vessels, coast guard vessels, some fishing vessels and inspectors. These reports contain basic information on date, position and species, but also additional information such as group sizes. These sightings are not useful for assessing abundance, but might reveal distributional aspects. Most of the reports come from the northern areas (Barents Sea); this is clearly related to the distribution of the activities which form the basis for this kind of reporting.
Report on the Danish Oceanographical Expeditions 1908-1910 to the Mediterranean and adjacent seas- Engraulidae-Clupeidae

Larvae of fish from families Engraulidae and Clupeidae were sampled.
Sampling was mainly pelagig, thus mainly by Petersen's young fish trawl. Data proceed from the Thor expeditions 1908-1910 but data from other expeditions (Thor 1905 and 1906) and other vessels (Nordboen and Pangan) are incorporated in the report, encompassing years 1904-1911.
Microzooplankton monitoring in the Mar Piccolo of Taranto. 2013-2014

Microzooplankton monitoring in the Mar Piccolo of Taranto, 2013-2014 in the framework of the Italian flagship project RITMARE.
In June 2013 and April 2014, sampling was carried out at four sites selected as representatives of different environmental issues and anthropogenic impacts 

Samples (5 L) were concentrated with a 10-μm mesh, reduced to 250 mL and immediately fixed with buffered formalin (4 % final concentration). Subsamples (10–25 cm3) were examined in a settling chamber using a Leica DMI 3000B inverted microscope equipped with phase contrast and bright-field illumination at ×200 magnification, according to the method of Utermöhl (1958). The entire surface of the chamber was examined. Among the microzooplankton communities, five main groups were considered and distinguished as ciliates (naked and tintinnids), heterotrophic dinoflagellates, other protozoa and micrometazoans. The phototrophic ciliate Mesodinium rubrum was treated together with the aloricate heterotrophic ciliates. Empty loricae of tintinnids were not differentiated from filled ones because tintinnid protoplasts are attached to the lorica by a fragile strand, which detaches with ease during collection and fixation of the samples. For each taxon, biovolumes were estimated by measuring the linear dimension of each organism with eyepiece scale and equating shapes to standard geometric figures. The obtained biovolumes were converted to carbon content by applying the following conversion factors and formulae according to Verity and Langdon (1984) for tintinnids, Putt and Stoecker (1989) for naked ciliates, Edler (1979) for athecate and thecate dinoflagellates and Beers and Stewart (1970) for other protozoa.
Northern shrimp (Pandalus borealis) in the Norwegian Deep and Skagerrak, 1984-2017

The survey data consist of: 1) one time series from 1984-2002 (October/November) using R/V Michael Sars and the Campelen-trawl; 2) a point estimate for 2003 (October) as R/V Michael Sars was taken out of service and substituted with R/V Håkon Mosby, whose winches at that time were not powerful enough for the Campelen-trawl, resulting in the survey being conducted with the Shrimp trawl 1420; 3) a start of a potential new time series as the survey in both 2004 and 2005 was conducted in May/June with R/V Håkon Mosby using the standard Campelen trawl; and 4) one time series from 2006 until present (January/February), using R/V Håkon Mosby and the Campelen trawl. From 2017 R/V Håkon Mosby has been substituted with R/V Kristine Bonnevie. In 2016, there were technical problems with the survey trawl (unequal wire lengths of the trawl gear) and this year’s data are considered to be non-representative of the stock status.
Senckenbergisches Sammlungsverwaltungssystem

Sesam is the Collection Management System of the Senckenberg Museum. SeSam was developed together with com2 (Bad Homburg). All collections (both zoological and botanical) of the Senckenberg Research Institute are going to use this efficient tool.
SeSam provides the following opportunities: 

Objects can have an aquatic, terrestrial, recent or fossil origin.

All collections are stores in a central database and use a joint data-pool for systematics, geographical data, persons and literature. This enables homogenous capturing of data. Collection spanning searches are possible.

Input of new collections is quick and easy. To add collection-specific fields and modulate the general templates is possible without programming knowledge.

SeSam is web-based.
Microphytobenthos in Panarea Island. ECO2 Project

Microphytobenthos collected in Panarea Island in the framework of ECO2 Project.
At all sampling stations and during all campaigns, sediment samples were collected by scuba divers with cut-off plastic syringes (2.6 cm i.d.). At each station and each sampling period, four sediment cores were sampled from which one was dedicated to the grain-size analysis and the remaining three to the microphytobenthic abundance (ABU) and community composition. 

Samplings were carried out during four sampling campaigns in the following periods: June and October 2012, May 2013 and May 2014. A total of five stations were sampled: three near Basiluzzo Island, characterised by different sediment colour and gas emission, and two NE of Panarea Island on a sampling site referred as “Hot-Cold” where the sediments are subjected to very different temperatures at a distance of approximately 1 m one from another. 


    For the quantitative determination of microphytobenthos (MPB), the uppermost sediment layer obtained from three distinct sediment cores was fixed with 10 mL of 4% formaldehyde buffered solution (CaMg(CO3)2) in pre-filtered seawater (0.2 μm filter) and stored at 4 °C until processing. For each sampling, three replicates were counted for the Basiluzzo samples and two for the Hot-Cold stations as for the latter the standard deviation did not exceed 15%. After manual stirring, 125 μL aliquots of the sediment suspension were drawn off and placed in a counting chamber. To obtain an estimate of the total viable cells, only cells containing pigments and not empty frustules were counted under a Leitz inverted light microscope (Leica Microsystems AG) using a 32× objective (320× final magnification) (Utermöhl, 1958).
    Microphytobenthos community was divided into major taxonomic groups and within the group of diatoms more precise species identification was attempted. Diatoms frustule cleaning was performed by oxidizing subsamples with two time volume of hydrogen peroxide (35%) and ≈1 mL of sulphuric acid (95–97%) (CEN, 2003). Between single treatments, the subsamples were heated over a Bunsen burner until boiling and left under the hood for 24 h. After that, they were washed with Milli-Q water and left to settle for at least 24 h between single washings, until reaching a pH close to 7. All samples were then mounted on permanent slides in Naphrax™ (Northern Biological Supplies Ltd. Ipswich, UK) and observed under 1000× final magnification using a light microscope (LM) (Leica DM2500, Germany) equipped with a digital camera (Leica DFC490, Germany).

European Seabirds At Sea (ESAS)

European Seabirds At Sea (ESAS) assembles offshore monitoring data on seabirds and marine mammals. This international database mostly includes data from the North Sea, yet large parts of the northeastern Atlantic Ocean are covered as well. It finds its origin in the 'Seabirds at Sea' project, which was initiated in 1979 following the discovery of major oil potential in the North Sea and an urgent need to gain more knowledge on the occurrence and distribution of seabirds in their offshore habitat. This led to the execution of large-scale ship-based surveys across the North Sea using a standardized data collection method and a first European-wide data assembly in 1991.
ESAS data are collected by various partners during aerial or ship-based surveys at sea and according to a methodology that allows to calculate georeferenced seabird densities. Standard practice further implies collecting as much information as possible on animal age, plumage and behaviour as well as observation conditions and distance to the observed individuals.

As part of the WOZEP research project, ESAS data were migrated in 2022 from its former host JNCC (UK) to ICES. The ICES infrastructure allows partners to submit new data and users to download or request data.
Spatial and seasonal variability of the molluscan macrofauna at the marine-lagoonal environmental gradient at Kalloni saltworks (Lesvos Island, NE Aegean Sea, Greece)

A study that focuses on the seasonal community structure of the macrobenthic molluscs at the marine-lagoonal environmental gradient that takes place at Kalloni solar saltworks (Lesvos Island, NE Aegean Sea, Greece).
The molluscan community was studied by means of four seasonal samplings carried out in 2004 at four sites located along the marine-lagoonal environmental gradient in the study area.

Four sampling sites, spread over a total distance of approximately 1 km, were chosen along the course of seawater flow from Kalloni Gulf into the saltworks and termed "gulf", "channel", "pond1" and "pond2", respectively. Sampling was repeated as four seasonal samplings in 2004 (in February – "Winter", May – "Spring", September – "Summer" and November – "Autumn"). Samples for the macrobenthic molluscs analyses (three replicates, 0.1 m2 each, tens of m apart) were collected with a Hydrobios Van Veen grab sampler and were subsequently sieved through a 0.5mm mesh size net. The samples were fixed with 4% formaldehyde and stained with Rose Bengal.

Microphytobenthos monitoring in the Mar Piccolo of Taranto. 2013-2014

Microphytobenthos monitoring in the Mar Piccolo of Taranto, 2013-2014 in the framework of the Italian flagship project RITMARE
In June 2013 and April 2014, sampling was carried out at four sites selected as representatives of different environmental issues and anthropogenic impacts 
At each station, scuba divers collected five virtually undisturbed sediment cores using polycarbonate sample tubes (12.7 cm I.D. with a sample area of 127 cm^2). The three remaining cores were brought to the laboratory, partially extruded, and the oxic sediment layer (0–0.5 cm ca) of each core was collected, homogenised and used for the grain size analysis as well as the quantitative and qualitative determination of microphytobenthos.

Phytoplankton data collected during Second Ukrainian Antarctic Expedition (March-April 1998) on board of R/V Krenkel

Dataset includes phytoplankton data collected during Second Ukrainian Antarctic Expedition (March-April 1998) on board of R/V Krenkel in the regions of South Orkney Islands, Drake Passage, Elephant Island and region of Ukrainian Antarctic Station.
Expedition was organized by Ukrainian Antarctic Research Center. Samples were taken by 7 L Niskin bathometer at standard depths: 0, 20, 25, 50, 75, 100 and 150m. Samples were concentrated by reverse filtration through nucleoporous (nuclear) filters with 1 µm size pores. Fixation - 40%  Formalgedid or Glutar. Cell counts were done with a light microscope (magnification 100, 200, 400 x). In addition samples were taken by 7 L Niskin bathometer from depths where irradiance level = 100, 46, 25, 10 and 1% and were processed without concentration in drop 0.1-0.5 ml (1-3 replications). Individual biovolumes and biomass (wet weight) were calculated via geometric approximations. 

At IBSS, the data were digitized from paper processing books, quality-controlled and transformed to comply with the Darwin Core/OBIS Schema. Funds for data operations were kindly provided by the Census of Marine Life International Cosmos Prize Fund, through a grant to Rutgers University.
