Surface Water Lead Concentrations Near Station ALOHA from 1997 to 2013

Station ALOHA in the Pacific Ocean is the location for this dataset of total dissolvable lead concentrations in surface water. It contains samples collected from 1997 to 2013 using the MITESS moored sampler and shipboard ATE sampling during HOT, HOE-DYLAN, and HOE-PhoR cruises. The dataset was authored by Edward A. Boyle of the Massachusetts Institute of Technology.

Use Cases

• Analyzing long-term trends in oceanic lead pollution based on the 1997-2013 time series.
• Modeling trace metal biogeochemistry based on concentration measurements from the North Pacific subtropical gyre.
• Calibrating or validating oceanographic sampling equipment based on the described MITESS and ATE methodologies.
• Studying the impact of specific research cruises (e.g., HOE-DYLAN) on observed chemical distributions.

Strengths

• Data spans a 16-year time range from 1997 to 2013.
• Samples were collected using specialized, documented equipment (MITESS, ATE).
• Dataset is hosted by BCO-DMO, a recognized repository for oceanographic data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
