Antarctic Peninsula Marine Geology Cruise Data from 2001

Cruise NBP01-07 collected eight types of marine geologic and oceanographic data around the northern Antarctic Peninsula. The project was a collaboration between Hamilton College and the Desert Research Institute, supported by NSF Award OPP-0003060. Data collection occurred in 2001, with the dataset archived in January 2002.

Use Cases

• Map seafloor topography using swath bathymetry data to identify submarine features.
• Analyze sediment core records up to 20 meters long for paleoclimate reconstruction.
• Correlate water column properties like temperature and salinity from CTDT measurements with sediment data.
• Study surface ocean conditions using underway measurements of pCO2, temperature, and Chlorophyll-a.
• Interpret sub-bottom stratigraphy from single-channel 3.5 kHz Chirp data.

Strengths

• Includes eight distinct, complementary data types for a multi-faceted study.
• Sediment cores provide long records, with some reaching 20 meters in length.
• 3.5 kHz Chirp data is noted as being of excellent quality.

Limitations

• Exact row counts, file sizes, and specific column schemas are unknown.
• Water column CTDT data is noted as being archived only at Hamilton College, potentially limiting access.
• Data is from a single cruise in 2001, offering a snapshot rather than a time series.
