Collections from 2002-2003 at harbor and reef sites on four Hawaiian islands recorded 1039 marine taxa. The survey identified 112 introduced or cryptogenic species, representing 10.9% of total taxa. Data was collected by researchers and archived by NOAA's National Centers for Environmental Information.
Use Cases
- Analyze the relationship between site type (harbor vs. reef) and the proportion of nonindigenous species (NIS) using the recorded 10.9% overall NIS component and harbor-specific rates up to 36%.
- Model the distribution of NIS abundance based on environmental factors like oceanic circulation exposure, using the documented gradient from isolated commercial harbors to exposed reef sites.
- Compare species richness (total identified taxa) between harbor and reef stations to understand habitat-specific biodiversity patterns.
- Identify the 11 species reported as new to Hawaii for further taxonomic or genetic study.
Strengths
- Records 1039 distinct taxa of marine algae, invertebrates, and fishes.
- 872 taxa (84% of total) are identified to the species level, enabling precise analysis.
- Provides a clear temporal snapshot from a focused 2002-2003 survey period.
Limitations
- Data is from a single, short time period (2002-2003) and may not reflect current conditions.
- Geographic scope is limited to eight specific harbor and reef sites on four Hawaiian islands.
- Sample data and column structure are unknown, which complicates initial data exploration.
