Ichthyoplankton Survey from Gulf of Mexico R/V Longhorn 1977

One year of ichthyoplankton data was collected during 1977 aboard the R/V Longhorn for the BLM/OCS South Texas Program. Dr. John H. Finucane of the National Marine Fisheries Service submitted the data, which was originally intended for NCEI Accession 7800506. These records were later consolidated under a different accession number.

Use Cases

• Analyzing ichthyoplankton species composition and abundance over the 1977 survey period.
• Mapping larval fish distribution using associated geospatial coordinates from the R/V Longhorn cruise.
• Correlating ichthyoplankton presence with environmental variables like sampling date and location.
• Establishing a 1977 baseline for Gulf of Mexico fish populations for comparative studies.

Strengths

• Data collected over a full annual cycle from January to December 1977.
• Originates from a defined research program (BLM/OCS South Texas) and a named scientific vessel.

Limitations

• Exact row count, column names, and sample size are unknown.
• Data is historically stale, representing a single year nearly 50 years ago.
• Consolidation under a new accession number (9000183) may complicate original data traceability.
