Description
Particle flux and net primary production data were collected from a single deep-ocean station in the Eastern Tropical Pacific over a ten-year period. The dataset, managed by the Korea Institute of Ocean Science and Technology (KIOST) and archived by NOAA, examines the composition and sinking flux of particles, including organic and inorganic carbon, to a depth of 4,950 meters. It captures a shift in the Pacific Decadal Oscillation around 2008, correlating with changes in carbon flux.
Use Cases
Analyzing the relationship between Pacific Decadal Oscillation phase shifts and deep-sea particulate carbon flux.
Quantifying long-term trends in calcium carbonate, coccolith, and foram flux in the deep ocean.
Correlating net primary production estimates with measured particle flux at a fixed station.
Studying the export of lithogenic material to the abyssal Eastern Tropical Pacific.
Strengths
Provides a continuous ten-year time series from 2003 to 2013 at a single location.
Includes specific measurements of particulate organic and inorganic carbon flux to a depth of 4,950 meters.
Captures a key climate transition event (PDO shift) within its observational period.
Limitations
Column names and exact row count are not provided by any source, limiting detailed analysis.
Data is confined to a single station, reducing spatial representativeness.
Conflicting last update dates exist between platforms (2013-07-31 on NASA Earthdata vs. 2026-03 05 on Data.gov).
Provenance
