NE Atlantic sediment trap data collected from a fixed platform at 34N 21W between April 1989 and April 1990. The dataset contains measurements of carbonate, biogenic opal, organic carbon, nitrogen, hydrogen, and phosphorous concentrations from traps deployed at depths of 1km, 2km, and 0.7km above the sea floor. Data were collected by Dr. S. Honjo of Woods Hole for the Joint Global Ocean Flux Study.
Use Cases
- Modeling biogenic sediment flux based on measured concentrations of carbonate and opal.
- Analyzing seasonal changes in organic carbon deposition based on the one-year collection period.
- Studying vertical particle flux gradients based on data from traps at three different depths.
- Investigating nutrient cycling based on measurements of nitrogen, hydrogen, and phosphorous.
Strengths
- Data covers a full annual cycle from April 1989 to April 1990.
- Measurements from three distinct depths (1km, 2km, and 0.7km above sea floor) provide vertical profile information.
- Includes analysis of six specific chemical components: carbonate, biogenic opal, organic carbon, nitrogen, hydrogen, and phosphorous.
Limitations
- Last updated 1990-04-09 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
