Submarine Volcanoes and Bathymetric Surveys in the Solomon Islands Forearc

Submarine volcanoes in the New Georgia Group forearc are reported anomalously close to the subduction line of the Woodlark Basin. The dataset includes descriptions of specific volcanoes like Kavachi, which rises nearly 1000 m and is frequently active, and Kana Keoki, which rises to within 700 m of sea level. It originates from the Australian Ocean Data Network and was last updated on 2026-04-16.

Use Cases

• Mapping submarine volcano locations based on reported coordinates and bathymetric survey data.
• Analyzing volcanic composition and activity based on described rock types (basalt-andesite, andesite-rhyolite).
• Assessing bathymetric survey gaps in the poorly surveyed New Georgia Group forearc region.
• Investigating hydrothermal vent activity versus volcanic eruptions based on historical event reports.

Strengths

• Includes specific depth measurements, such as Kavachi rising nearly 1000 m and Kana Keoki rising from 2500 m to 700 m below sea level.
• References specific historical surveys and events, such as bathymetric surveys in 1979 and 1981 and reported activity in 1963-4.
• Provides geographic context with distances between features, like a seamount 9 km northeast of Kavachi.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description states the region is 'very poorly surveyed bathymetrically', indicating incomplete spatial coverage.
