Deep Sea Precious Corals 2004 Expedition Video Archive

Hawaiian Archipelago deep-sea video footage was collected from October 2 to 18, 2004, during the Deep Sea Precious Corals Expedition. The dataset contains video products from the R/V Ka'imikai-o-Kanaloa, the Human Occupied Vehicle Pisces V, and the Remotely Operated Vehicle RCV-150. It documents coral-associated invertebrate fauna at three large precious coral beds, including Cross Seamount, Keahole Point, and Makapuu.

Use Cases

• Cataloging coral-associated invertebrate species based on video observations.
• Mapping the distribution of precious coral beds at specific seamounts and points.
• Studying deep-sea benthic habitats and biodiversity from submersible footage.
• Comparing faunal communities across three distinct coral bed locations.
• Providing visual reference material for deep-sea expedition research and education.

Strengths

• Contains video from multiple platforms (ship, HOV, ROV) for multi-perspective observation.
• Documents a focused, multi-week expedition to three specific precious coral beds.
• Geospatial tags indicate specific locations like Cross Seamount, Keahole Point, and Makapuu.

Limitations

• Column names and data structure are unknown, limiting detailed analysis.
• Conflicting 'last updated' dates (2004 vs. 2026) create uncertainty about metadata maintenance.
• No information on video count, resolution, duration, or access formats is provided.
