Questions related to North Sea
Recently we found this bivalve in our samples near port of Zeebrugge (Belgium) (see pictures).
The shell was damaged trying to open it.
This is probably the first finding of this bivalve in the Belgian part of the North Sea?
Any tips of species name are welcome
regards,
JW
Hello All,
This discussion is meant to be for researchers who are currently working on Equinor's latest data release (https://data-equinor-com.azurewebsites.net/). The purpose of the discussion is to provide a platform whereby researchers can discuss any difficulties they may be experiencing with the dataset.
"Volve is a decommissioned field in the central part of the North Sea and was discovered in 1993, the plan for development and operation (PDO) was approved in 2005 and was on stream in 2008. The field was shut down in 2016. Together with the license partners Equinor has now decided to release the most important subsurface data for Volve." (Equinor, 2018)
Looking forward to your contributions.
Sincerely,
Muhammad Said Abdallah
As I am working on a project of WWF NL (Sharks and Rays back into the North Sea), I would be really interested in learning more about this project.
We found this small, maybe parasitic, crustacean in the North Sea offshore. The posterior body part is missing, but it looks quite characteristic. There is double-hooked rostrum, 2 antennae (second pair broken off), 2 small eyes on each side of head, no coxal plates, and maybe a sucker-like structure near mouthparts.
Stained with Shirlastain A.
We don't have any clue to which higher group it belongs, and would be happy if anyone can give a hint.
I'm currently working on OM sources fueling fish communities in the North Sea. I have a dataset of C and N isotopic ratios for fish and I would like to include benthic, pelagic and riverine OM end-members in an isotopic mixing models. I have values for benthic and pelagic productions, but I can’t find papers presenting isotopic ratios for main rivers flowing into the North Sea. Is someone aware of such dataset?
Thanks in advance
This sediment dwelling cnidarian was found within a benthic sediment grab at 170m depth north east of the Shetland Islands in the North Sea. Can anyone suggest a particular species?
Any help would be very much appreciated,

Hey guys,
attached you find the picture of an algae from the North Sea/English channel, to be more precise rocky shore coast of Wimereux, Nord-pas-de-Calais, northern France.
Is anyone able to identify the species or at least family or genus?
Even my professors weren´t able to identify it.
Much appreciated!
During analysis of macrozoobenthic samples from North Sea waters off Scotland we were aware of several structures (see attached images) which were used by Paguridae as houses. Who can help to identify the "manufacturers" of these curious "organ pipes" made of sand corns.
Found this individual or a part of an unknown species in the Dutch North Sea, shallow waters, <20m depth. I have no idea, so I think it may just be a part of another animal (bivalve?). I made a section of the specimen showing the internal organs? Does somebody recognize this?

We found this flatworm in a sample from a sandy bottom in the North Sea. Length about 4 cm, 2 groups of tentacular eyespots, with <10 tiny eyespots scattered evenly in a small area around tentacular eyespots. Dark colour of intestinal branches disappeared after some hours in captivity.
I am currently modelling the potential distribution of the invasive Caprella mutica and native species of Caprellidae (for starters C. linearis) in the North Sea. From my own work I have obtained several offshore samples in the Dutch part of the North Sea. Furthermore I have received data from colleagues in other countries, but the total dataset is still very small. From literature I have obtained hundreds of presence-only observations (e.g. from Cook et al., 2007). But I found hardly any presence-absence data of Caprellidae.
Is there anyone that has this type of data from the North Sea and is interested in sharing this? Thank you for reading my question!
A pair of specimens were found underneath the carapax of an Upogebia deltaura juvenile of about 14mm in length. Underneath the left side a male was visible with a curious pair of blackish longitudinal lines. When I removed it from the gills, it was attached to the underside of a larger female, also with a pair of blackish longitudinal lines.
They were found on the Oystergrounds in The Dutch part of the North Sea on 21.iii.2015 at the a depth of 49m. ED50: 54°10’00” N 4°26’00” E
Could anybody give me a hint of the genus/species and/or a paper/reference on this taxon?
many thanks in advance
Found the same species in two other samples from the same area (Cleaverbank, North Sea), also from underneath the carapax of Upogebia deltaura. One Upogebia with one male and one female of about the same age/development and another Upogebia with only a female, but more developed. The latter female is shown in this picture. Still suggestions are welcome, and I hope i will ever find a mature one.
Yet we found another type of Brachiopod from the Cleaverbank in the Dutch North Sea. Previously we recorded Terebratulina retusa from the same area, but this is something completely different. One valve is flatter than the other and the surface of both valves have a dense but regular pattern of pores. If anybody could make a suggestion it would be most welcome. We have orderder a book on British Brachiopods, but we don't have this yet, but I'm very curious.
Sample from 30.vi.2015, depth 38.1m, UTM31N 505400/5981650
Hello ladies & gentlemen,
Does anyone know where I can source high resolution chlorophyll concentration data for the North Sea region from present day back to 2004 for free other than NASA Earth Observations (NEO)?
Any help would be greeted with the upmost appreciation.
Thank you,
Edward Lavallin

We did measurements of the formation of nanometer sized atmospheric particles in the North Sea atmosphere during March-July 2012 and wonder if periods with algae blooming can give emissions of different organic gaseous compounds from the water surface to the air and cause the formation of these particles?
Or if there is some other process in the water that can correlate or anticorrelate with the new particle formation? Also an explanation of how different processes/activities in the water can give varying emissions of gaseous organic compounds would be highly appreciated.
The Dutch part of the North Sea is predominantly sandy or muddy and its benthic life consists of animal species adapted to these sediments. Life on and around shipwrecks shows a strong contrast because it is made up of species preferring hard substratum. Consequently, wreck fauna adds significantly to the total biodiversity. Moreover, it contains several higher taxa such as sponges, hydroids, sea anemones, bryozoans and nudibranchs, which are hardly represented on sandy and muddy substrates. Also the fish community seems to be enriched as we encounter high numbers of fish like Gadoids swimming close to wrecks, a phenomenon well known to the sport-fishing community. Not surprisingly, wrecks have been compared to ‘oases in a desert’.
However, wrecks are considered artificial substrates and as such do not gain much protection in frameworks such as the European Habitat Directive, which often focus on more ‘natural’ communities. We may ask ourselves whether this is correct: next to the added value in terms of biodiversity, the biological communities of wrecks and other hard-substrate objects such as oil rigs resemble communities that have been present in the past such as oyster banks and exposed peat (‘moorlog’). These substrata have almost disappeared during the last century probably due to anthropogenic activities.
What is the ecological relevance of life on and around shipwrecks in your country?
