Surface and Profile Concentrations of Trace Metals and Radionuclides near Station ALOHA

Trace element water samples from the North Pacific Ocean near Station ALOHA were collected during cruise KM1513 using specialized MIT Automated Trace Element samplers. The dataset includes surface and depth profiles, with samples filtered and acidified at sea following established protocols for direct comparison with prior work. It was created by C. Hayes of the Massachusetts Institute of Technology and is hosted by the Biological and Chemical Oceanography Data Management Office.

Use Cases

• Modeling oceanic trace metal distributions based on surface and depth profile concentrations.
• Studying radionuclide transport and cycling in the water column near a long-term oceanographic station.
• Assessing contamination prevention efficacy based on the described specialized sampling methodology.
• Comparing trace element concentrations with historical data from Station ALOHA.

Strengths

• Samples were collected using specialized MIT Automated Trace Element samplers designed to prevent contamination.
• Processing followed published protocols for direct comparison with prior work at Station ALOHA.
• The dataset is hosted by the Biological and Chemical Oceanography Data Management Office (BCO-DMO), a recognized repository.

Limitations

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