Transmission Electron Microscopy Images of Foraminifera from an Arctic Methane Seep

Transmission Electron Microscopy images of the foraminifera species Nonionellina labradorica used in a feeding experiment. The samples were collected from Gas Hydrate Pingo 3, approximately 50 km south of Svalbard in the Barents Sea. The dataset was created by Christiane Schmidt of the Centre National de la Recherche Scientifique for a publication.

Use Cases

• Analyze cellular ultrastructure of foraminifera based on TEM images.
• Study potential symbiosis or feeding interactions between foraminifera and methanotrophs based on the described experiment.
• Validate findings from the associated publication DOI: 10.5194/bg-2021-284 using the original image data.

Strengths

• Images are from a specific, geolocated Arctic methane seep site (76°6'23.7"N 15°58'1.7"E).
• Dataset is directly linked to a published scientific study with a DOI.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
