On 3 April 2001, a 20 kg point source of fluorescein dye was released 30 m above the bottom of the active summit caldera of Vailulu’u submarine volcano, Samoa. Vailulu’u crater is 2000 m wide and at water depths of 600–1000 m, with the bottom 200 m completely enclosed; it...
Investigations of the behavior of the geomagnetic field on geological timescales rely on globally
distributed data sets from dated lava flows. We present the first suitable data from the Arctic region,
comprising 37 paleomagnetic directions from Jan Mayen (71°N, 0.2–461 ka) and Spitsbergen (79°N, 1–9.2 Ma) and five paleointensity results....

The summit crater of Vailulu’u Seamount, the youngest volcano in the Samoan chain, hosts an active
hydrothermal system with profound impact on the ocean water column inside and around its crater (2 km
wide and 407 m deep at a 593 m summit depth). The turbidity of the ocean water...
Vailulu'u Seamount is identified as an active volcano marking the current location of the Samoan hotspot. This seamount is located 45 km east of Ta'u Island, Samoa, at 169°03.5′W, 14°12.9′S. Vailulu'u defines the easternmost edge of the Samoan Swell, rising from the 5000‐m ocean floor to a summit depth of...
Many disciplines of geochemistry have no data reporting standards, and their use of metadata is inadequately developed. This presents problems to the quality of the published science, and it limits the utility of computers in data analysis and the exploitation of Information Technology (IT). We discuss problems of data and...
