Studies of Beaks and Parasites of Antarctic Cephalopods from 1991 Prydz Bay Survey

ASAC Project 11 data from the Australian Antarctic Division documents a 1991 survey of pelagic and benthic fauna in Prydz Bay, Antarctica. The dataset includes capture records for 341 cephalopod specimens, comprising 256 squids and 85 octopods, across eight squid and two octopod species. Sampling occurred from January to March 1991 using IYGPT hauls at three depths across 63 stations and bottom trawls at 21 sites.

Use Cases

• Modeling species distribution based on capture depth and location data mentioned in the description.
• Analyzing ontogenetic descent patterns based on evidence for Galiteuthis glacialis.
• Studying benthic versus pelagic habitat use based on sampling methods (IYGPT vs. bottom trawl).
• Investigating diel vertical movement patterns for which no distinctive pattern was found.

Strengths

• Includes 341 cephalopod specimens with counts for squids (256) and octopods (85).
• Sampling details are provided, including 63 pelagic stations and 21 benthic trawls.
• Covers eight identified squid species and two octopod genera.

Limitations

• Last updated 1991-03-31 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.
