The largest deep-ocean silicic volcanic eruption of the past century.

The 2012 submarine eruption of Havre volcano in the Kermadec arc, New Zealand, is the largest deep-ocean eruption in history and one of very few recorded submarine eruptions involving rhyolite magma. It was recognized from a gigantic 400-km2 pumice raft seen in satellite imagery, but the complexity of this event was concealed beneath the sea surface. Mapping, observations, and sampling by submersibles have provided an exceptionally high fidelity record of the seafloor products, which included lava sourced from 14 vents at water depths of 900 to 1220 m, and fragmental deposits including giant pumice clasts up to 9 m in diameter. Most (>75%) of the total erupted volume was partitioned into the pumice raft and transported far from the volcano. The geological record on submarine volcanic edifices in volcanic arcs does not faithfully archive eruption size or magma production.

A database to record, track and report health student rural placements.

The Spencer Gulf Rural Health School (SGRHS), South Australia, is funded by the Australian Commonwealth Government to deliver health education in the rural setting. The SGRHS required a database to record, track and report on student rural placements to satisfy Commonwealth reporting requirements, and for internal academic and administration staff use. Staff in widely separate rural locations needed to be able to access the database. A web-based relational database was created using Microsoft Access. The student rural placement database has been successfully utilised as the primary tool to record and track student placements in the SGRHS for 2 years, and has generated data for eight Commonwealth reports in this time. Future database developments include student accessible sections. With few alterations the database could be utilised by other Australian Rural Clinical Schools and University Departments of Rural Health.

Interactive videoconferencing system for rural health education: a preliminary report.

OBJECT: To establish a videoconferencing network in a new Rural Clinical School. DESIGN: A report on choosing hardware and connecting multiple sites simultaneously. SETTING: Rural South Australia. SUBJECTS: Undergraduate medical, nursing and allied health students. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Establishment of an effective multisite, dual mode videoconferencing system. RESULTS: The choice of hardware was simple, but acquiring adequate broadband connection between sites proved difficult. CONCLUSIONS: Multi-site meetings for academic and administrative purposes are now routine. Evaluation of the effectiveness of medical education delivery will occur throughout 2004.
