High-resolution oxygen isotope data from planktic foraminifera in sediment cores collected offshore Montserrat during IODP Expedition 340. The dataset provides an age framework for the upper ~300,000-year sections of three cores, with sampling resolution estimated at every 2000 years. This work was funded by NERC grant NE/K002724/1 and involves collaboration with scientists from the University of Massachusetts and Florida State University.
Use Cases
- Reconstructing the volcanic eruption history of Montserrat based on high-resolution sediment core stratigraphy.
- Analyzing global climate and ice volume changes over the last ~300,000 years using oxygen isotope ratios.
- Correlating marine sediment records to a global paleoclimate framework for detailed age modeling.
- Investigating landslide events in the Lesser Antilles volcanic arc as recorded in interrupted sediment sequences.
Strengths
- Provides a high-resolution age framework with sampling estimated every 2000 years.
- Extends the volcanic activity record of Montserrat back to an estimated 4.5 million years in Hole U1396C.
- Core U1396C is 139.4 meters long, offering a long continuous sediment record.
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 bias inherent to the specific IODP expedition sites.
