Management considerations for the Heard Island lava tube caves

Management Considerations for the Heard Island Lava Tube Caves

Heard Island contains a system of lava tube caves in a largely pristine condition which are the best developed bedrock caves known in Antarctic or Subantarctic latitudes. They require special management, because of significant and sometimes fragile attributes associated with cave geomorphology, geology, hydrology, atmospheres, soils, microbiology, flora, fauna, vertebrate palaeontology, archaeo...

Lava penetrating water: Submarine lava flows around the coasts of Pico Island, Azores

[1] Bathymetry data collected with a multibeam echo sounder around Pico Island, Azores (Portugal), reveal a remarkable series of lava flows on the island’s shelf with a variety of pristine structures that suggest how lava behaves on entering water. Many flows are dendritic in plan view, some with channels and tumuli. Dendritic geometries are interpreted to arise from flow fronts repeatedly arre...

The Biogeography of Shallow-water Macrofauna Heard Island

Collections of23 macroinvertebrate taxa associated with Durvillaea antarctica hold fasts and 58 invertebrate taxa associated with artificial substrata coliectots are described flOm shallow-water and intertidd habitats at Heard Island. The fauna strong biogeographic affinities with the Kerguelen Island fauna and, to a slightly lesser extent, the fauna recorded at Macquarie Island but negligible ...

Path Planning and Navigation Inside Off-World Lava Tubes and Caves

Detailed surface images of the Moon and Mars reveal hundreds of cave-like openings. These cave-like openings are theorized to be remnants of lava-tubes and their interior maybe in pristine conditions. These locations may have well preserved geological records of the Moon and Mars, including evidence of past water flow and habitability. Exploration of these caves using wheeled rovers remains a d...
