Abstract: Pumice rafts are floating mobile accumulations of low-density pumice clasts generated by silicic volcanic eruptions. Pumice in rafts can drift for years, become waterlogged and sink, or become stranded on shorelines. Here we show that the pumice raft formed by the impressive, deep submarine eruption of the Havre caldera volcano (Southwest Pacific) in July 2012 can be mapped by satellite imagery augmented by sailing crew observations. Far from coastal interference, the eruption produced a single km 2 raft in 1 day, thus initiating a gigantic, high-precision, natural experiment relevant to both modern and prehistoric oceanic surface dispersal dynamics. Observed raft dispersal can be accurately reproduced by simulating drift and dispersal patterns using currents from an eddy-resolving ocean model hindcast. For future eruptions that produce potentially hazardous pumice rafts, our technique allows real-time forecasts of dispersal routes, in addition to inference of ash umice deposit distribution in the deep ocean.

Abstract: Abstract. An International Ocean Discovery Program (IODP) workshop was held at Sydney University, Australia, from 13 to 16 June 2017 and was attended by 97 scientists from 12 countries. The aim of the workshop was to investigate future drilling opportunities in the eastern Indian Ocean, southwestern Pacific Ocean, and the Indian and Pacific sectors of the Southern Ocean. The overlying regional sedimentary strata are underexplored relative to their Northern Hemisphere counterparts, and thus the role of the Southern Hemisphere in past global environmental change is poorly constrained. A total of 23 proposal ideas were discussed, with ∼ 12 of these deemed mature enough for active proposal development or awaiting scheduled site survey cruises. Of the remaining 11 proposals, key regions were identified where fundamental hypotheses are testable by drilling, but either site surveys are required or hypotheses need further development. Refinements are anticipated based upon regional IODP drilling in 2017/2018, analysis of recently collected site survey data, and the development of site survey proposals. We hope and expect that this workshop will lead to a new phase of scientific ocean drilling in the Australasian region in the early 2020s.

Abstract: An important stage in global ocean overturning circulation is the upwelling of the Antarctic Bottom Water into the Pacific Deep Water (PDW). The long‐term evolution of PDW circulation, however, is scarcely addressed. We use seismic reflection data and cores from the International Ocean Discovery Program (and its predecessors) in contourites to reconstruct regional deep ocean circulation patterns. Here, we demonstrate that PDW circulation was progressively enhanced at about 4.35, 3.84, 2.16, and 0.97 Ma since the early Pliocene. Coeval growth of volcanic arcs and tectonic uplifts gradually isolated marginal seas from the PDW and, in conjunction with climate cooling, effectively increasing deep‐water flux within a shrinking Pacific basin. Regional stratigraphic discontinuities in contourites indicate thresholds in the intensification of ocean circulation.
