Records of kelp rafts observed within 50 meters of a research vessel over one-hour periods in subantarctic latitudes. The data includes raft size, species, holdfast presence, latitude, longitude, and ship speed. Metadata originates from ASAC Project 2163 and was last updated by the Australian Antarctic Data Centre in December 2000.
Use Cases
- Modeling invertebrate dispersal pathways based on latitude and longitude coordinates.
- Analyzing species association with kelp rafting based on recorded species and holdfast presence.
- Studying raft size distribution and frequency in subantarctic waters.
- Correlating dispersal observations with environmental conditions inferred from location and time.
Strengths
- Observational protocol is specified: records from within 50 meters over replicated one-hour periods.
- Geographic scope is clearly defined: data collected over subantarctic latitudes only.
- Key variables are listed: size, species, holdfast presence, latitude, longitude, and ship speed.
Limitations
- Last updated 2000-12-23 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
