Coiling Direction Counts for Neogloboquadrina atlantica from IODP Expeditions 395C and 395

Counts of left and right-coiling specimens of the planktonic foraminifer Neogloboquadrina atlantica from sub-seafloor core samples. The data were collected by the International Ocean Discovery Program during Expeditions 395C (5 June - 6 August 2021) and 395 (12 June - 12 August 2023) in the North Atlantic. The dataset is provided by the British Geological Survey under NERC Grant NE/Y001745/1.

Use Cases

• Reconstructing past oceanographic conditions based on coiling ratio changes.
• Analyzing paleoclimate signals in the North Atlantic based on foraminifera data.
• Calibrating foraminifera-based climate proxies based on coiling direction counts.
• Studying population dynamics of Neogloboquadrina atlantica based on specimen counts.

Strengths

• Data originates from the International Ocean Discovery Program, a major scientific ocean drilling effort.
• Samples are temporally anchored to specific IODP expeditions in 2021 and 2023.
• Geographic focus is explicitly the North Atlantic.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal/source bias inherent to the specific IODP expeditions.
