Description
Micropaleontological data from the Antarctic Peninsula region focuses on foraminifera, ostracodes, and calcareous nannofossils from the Mesozoic and Cenozoic eras. The dataset, from the SCIOPS organization, aims to establish a high-latitude biostratigraphic framework and infer paleoenvironmental parameters. Research was planned over a multi-year project targeting specific islands and geological ages.
Use Cases
Define biozones using assemblage, FO (First Occurrence), and LO (Last Occurrence) data from foraminifera and nannofossil records.
Infer paleo-salinity and temperature parameters by analyzing the distribution and migration patterns of phytoplankton and zooplankton fossils.
Correlate and refine sedimentary rock ages in the James Ross Basin by comparing micropaleontological results with ammonite and bivalve biostratigraphy.
Compare high-latitude fossil associations from King George Island with global standards from Ocean Drilling Program cores.
Strengths
Integrates multiple microfossil groups (foraminifera, ostracodes, calcareous nannofossils) for cross-verification.
Explicitly targets comparison with Ocean Drilling Program core data for global context.
Research design covers multiple islands (James Ross, Cockburn, King George) and geologic periods (Oligocene, Miocene, Pliocene).
Limitations
Sample size and row count are unknown, limiting statistical assessment.
Data from King George Island is described as scarce and fragmented across disciplines.
Temporal coverage and specific time range for the collected samples are not quantified.
Provenance
Source
SCIOPS via NASA EarthData (nasa_earthdata).
Collection Method
Micropaleontological analysis of sedimentary sequences from specific Antarctic islands.
Time Range
Mesozoic and Cenozoic eras, with specific focus on Oligocene, Miocene, and Pliocene epochs.
Geography
Northwest and southeastern Antarctic Peninsula, including James Ross Island, Cockburn Island, South Shetland Islands, and King George Island.
