Description
One year of oceanographic data collected during five research cruises in the Northwest Atlantic from September 23, 1981 to September 27, 1982. The dataset includes conductivity, temperature, depth (CTD), nitrate, and cloud amount/frequency measurements from NOAA ships Delaware II and Albatross IV. Data was submitted by the National Marine Fisheries Service (NMFS) in Woods Hole, MA, and is processed in the NODC F022-CTD-Hi Resolution format.
Use Cases
Analyze nitrate concentration variations with depth (CTD profiles) to study nutrient availability for phytoplankton.
Correlate cloud amount/frequency data with sea surface temperature measurements from the CTD to investigate air-sea interactions.
Map the spatial and temporal distribution of conductivity and temperature data to track the movement of Warm Core Rings.
Use time-series data from five cruises to examine seasonal changes in oceanographic parameters in the Northwest Atlantic.
Strengths
Data spans a full year with five distinct sampling cruises, providing temporal coverage.
Includes multiple concurrent physical and chemical measurements (CTD, nitrate, cloud data).
Collected by authoritative NOAA research vessels and submitted by the National Marine Fisheries Service.
Limitations
Dataset is over 40 years old (1981-1982), limiting analysis of contemporary ocean conditions.
Geographic coverage is limited to the Northwest Atlantic, specifically west of 40°W.
Specific sample size, row count, and data resolution are unknown from the provided metadata.
