Heard Island Zooplankton and CTD Data from 1990 and 1992 Voyages

Zooplankton composition, krill, and CTD data collected during two marine science voyages to the Heard Island area. The HIMS voyage occurred in May-June 1990, and the FISHOG voyage from January to March 1992. Data were compiled by Angela McGaffin for ASAC Project 473.

Use Cases

• Analyze zooplankton community structure based on species composition data.
• Study krill distribution and abundance in the Heard Island region.
• Correlate biological observations with oceanographic conditions based on CTD data.
• Investigate seasonal or inter-annual changes in the marine ecosystem between the 1990 and 1992 voyages.

Strengths

• Data originates from two dedicated marine science voyages with known timeframes.
• Includes multiple complementary data types: CTD, krill, and zooplankton data.
• Original and processed data versions are available for comparison.

Limitations

• Last updated 1992-03-31 23:59:59.999000; 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.
