Deep-sea hydrothermal vents in the western Pacific are increasingly being assessed for their potential mineral wealth. To anticipate the potential impacts on biodiversity and connectivity among populations at these vents, environmental baselines need to be established. Bathymodiolus manusensis is a deep-sea mussel found in close association with hydrothermal vents in Manus Basin, Papua New Guinea. Using multiple genetic markers (cytochrome C-oxidase subunit-1 sequencing and eight microsatellite markers), we examined population structure at two sites in Manus Basin separated by 40 km and near a potential mining prospect, where the species has not been observed. No population structure was detected in mussels sampled from these two sites. We also compared a subset of samples with B. manusensis from previous studies to infer broader population trends. The genetic diversity observed can be used as a baseline against which changes in genetic diversity within the population may be assessed following the proposed mining event.

Trachinocephalus gauguini Polanco, Acero & Betancur, 2016 was described based on eighteen specimens collected from off the Marquesas Islands, the only location where this species has been recorded until now. Through morphological and molecular examination of Trachinocephalus specimens collected from an exploratory cruise conducted in June 2014 under the Tropical Deep-Sea Benthos program along the northern coast of the New Ireland Province, Papua New Guinea, we demonstrate the presence of this species in Papua New Guinea waters. This new record suggests a wide distribution for this rarely collected species in the western Pacific Ocean.

AbstractScripted as a sustainable alternative to terrestrial mining, the licence for the world’s first commercial deep-sea mining (DSM) site was issued in Papua New Guinea in 2011 to extract copper and gold from a deposit situated 1600 m below the surface of the Bismarck Sea. Whilst DSM’s proponents locate it as emergent part of a blue economy narrative, its critics point to the ecological and economic uncertainty that characterises the proposed practice. Yet, due its extreme geography, DSM is also profoundly elusive to direct human experience and thus presents a challenge to forms of resistance against an industry extolled as having ‘no human impact’. Against this background, this paper analyses the ways in which ‘blue degrowth’—as a distinct form of counter-narrative—might be ‘performed’, and which imagined (and alternative) geographies are invoked accordingly. To do this it critically reflects upon 2 years of participatory research in the Duke of York Islands focusing on three, community-developed methods of resisting DSM. Practices of counter mapping, sculpture and participatory drama all sought to ‘perform’ the deep-ocean environment imagined as relational whilst simultaneously questioning the very notion of ‘economy’ central to the discourse of ‘blue growth’.
