Siphonophore (hydrozoaire) Rhizophysa filiformis
Salpe (tunicier pélagique) Doliolum denticulatum
Après Roscoff, une nouvelle mission #DIVE-Sea par @mnhn.fr avec #MIO @univ-amu.fr cible cette fois les espèces gélatineuses pélagiques, étranges et mal connues !
Ex: le siphonophore (hydrozoaire) Rhizophysa filiformis ou la salpe (tunicier pélagique) Doliolum denticulatum
@atlasea.bsky.social
Species sequenced by Project Psyche also contribute to the aims of other projects including ERGA and EBP www.cell.com/trends/ecolo...

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.
Ie: it's not us (Samtools team)! Be warned
🌊 Exploring the Ocean’s Genetic Secrets! Guided by @jm-aury.bsky.social and France Denoeud, @lafucarmen.bsky.social Doctoral Candidate at Genoscope - Centre National de Séquençage, shares how she's using long-reads on marine samples from the Tara Oceans expedition to explore genetic novelty.
ATLASea Mission – Day 6
In the dissection room, the final sampling steps are underway
🔬 Tissue fragments are collected, labeled, weighed, and logged into a data sheet for full traceability
❄️ Samples are flash-frozen in liquid nitrogen at -196°C to preserve DNA quality for sequencing at Genoscope
📸 ATLASea Mission – Day 4 - photography
Each selected specimen is individually photographed in the photo room by 3 dedicated teams.
🗂️ Images are paired with species sheets + unique ATLASea & MNHN labels to ensure full data traceability.
Next stop: the dissection room!
#MarineGenomics #Biodiversity
ATLASea has just launched a new sampling campaign in one of the most iconic sites of marine biodiversity.
For the next 10 days, our team of researchers will be working around the #Endoume_Marine_Station in Marseille to collect samples of marine species from the surrounding area.
🔍 ATLASea Mission – Day 3
Taxonomic experts examine each specimen, compare it to reference catalogs, and confirm ID - sometimes with help from global colleagues!
If the species is new to sequencing efforts, it’s selected (GO)
If not, it’s returned to the sea (NO GO)
#MarineBiodiversity #Fieldwork
@atlasea.bsky.social Sampling Day 2
Samples from the sea head straight to the wet lab for taxonomic grouping.
Dragged sediments are sieved and size-fractioned - revealing hidden benthic diversity.
Uncertain samples go into aquaria, then safely back to the sea if not selected.

🐚 𝑳𝒊𝒎𝒂𝒓𝒊𝒂 Leads the Way — ATLASea Hits 1500 with a Mollusc That Claps! 🎉🎉
The #DIVE-Sea team has sampled the 1500th species for #ATLASea this week in Marseille!
𝑳𝒊𝒎𝒂𝒓𝒊𝒂 𝒕𝒖𝒃𝒆𝒓𝒄𝒖𝒍𝒂𝒕𝒂, a gorgeous bivalve mollusc of the family 𝐿𝑖𝑚𝑖𝑑𝑎𝑒, first described in 1792 by Giuseppe Olivi.

1/ We made a tool called Vizitig to explore sequencing datasets visually, interactively, and with metadata.
It uses a colored de Bruijn graph under the hood.
This week, ATLASea is in the Endoume marine station from @univ-amu.fr for a new sampling expedition focused on fish and some additional species! The team has already collected 30 new species.
In the lab, our colleagues Caroline, Janaina and Morgane sampling tissues from a coral.
