Nutrient concentration targets to achieve periphyton biomass objectives incorporating uncertainties

Ton Snelder
Nutrient concentration targets are an important component of efforts to manage the eutrophication of gravel-bed streams and rivers worldwide. In New Zealand, the periphyton attribute of the National Objectives Framework (NOF) National Policy Statement for Freshwater Management (NPS-FM) requires that nutrient concentration targets are set to achieve periphyton biomass objectives. Although guidance exists for setting nutrient concentration targets, there remains considerable uncertainty about what the appropriate nutrient concentration targets should be for any location. In...

Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS V)

Daniel H. N. Barker, Laura M. Wallace, K. Woods, M. Savage &
HOBITSS V was a 12-day (6–18 October 2018) Wellington to Wellington R/V Tangaroa voyage (TAN1809). Objectives of TAN1809 were to undertake seafloor geodetic and seismic instrument deployments, recoveries, and surveys offshore the Gisborne, Mahia, and Wairarapa coasts. The seafloor geodetic aims involve using Bottom Pressure Recorders (BPRs) to determine the cm-level vertical movement (upward or downward) of the seafloor during slow slip events and to deploy two new precision transponder arrays to monitor cmlevel horizontal...

Art meets science: the centre of New Zealand's Continental Shelf

Jenny Black & Cornel E.J. de Ronde
The centre of New Zealand’s Extended Continental Shelf was calculated using a Lambert Conformal Conic projection with the projection parameters progressively improved in an iterative manner to find a precise solution. It lies on land near the Mt Reeves Track in the Tararua Ranges at 175.36229°E, 41.01821°S. Artist Billy Apple designed an artwork that was installed on the 29th March 2019 by GNS Science and the Department of Conservation to mark the location. (auth)

Resource management decisions and data requirements to support the Smart models for aquifer management research programme

Abigail P. Lovett, M Gyopari, Magali F. Moreau, Catherine R. Moore & Paul A. White
To help meet objectives set under the New Zealand Government’s National Policy Statement for Freshwater Management appropriate modelling tools are required to assist land and water management decision-making. The principal objective of the smart models for aquifer management research project (SAM) is to develop a decision-specific ‘smart’ modelling framework that takes into consideration modelling objectives and scenarios, available data and resources. Importantly, ‘smart’ models also consider the computational burden of large groundwater flow and transport...

Auckland, New Zealand, home to a third of New Zealanders, is built on top of the Auckland Volcanic Field (AVF): a mostly monogenetic field of 53 known volcanic vents. The personal, societal, and economic cost of a future AVF eruption are likely substantial, depending on location and crisis response and recovery actions. Estimates of the duration of detectable unrest in the leadup to an AVF eruption range from hours to weeks or longer. Volcano monitoring...

Short-term preparation for and response to an impending lava flow: lessons from the June 27th lava flow (2014-2015), Hawaii, USA

S. W. R. Tsang, Jan M. Lindsay & Natalia I. Deligne
On 27 June 2014, a lava flow began erupting from Kīlauea Volcano that eventually threatened the town of Pāhoa, Hawaii, USA. As the lava flow approached town limits, Hawai‘i County Civil Defense led local scientists, government agencies, non-governmental organisations and local businesses in efforts to prepare the town for potential impacts. Key measures included holding at least daily press conferences and weekly community meetings, building three evacuation routes, creating power pole protection structures and building...

Translating natural hazard science into policy and practice: 'It's Our Fault' course summary and recommendations report

Sarah N. Gunnell
Effective natural hazard planning policy and practice for managing the risk faced by our communities needs to be informed by science. While scientific information on the natural hazards New Zealand is exposed to continues to increase, this information often struggles to be translated into planning policy and practice. In particular, the ‘It’s Our Fault’ (IOF) research programme that began in 2006 has generated a significant amount of scientific information on the likelihood and consequences of...

The geometry and evolution of the boiling zone that produced the Favona ore bodies in the Hauraki Goldfield, and the implications for exploration

Stuart F. Simmons
The Favona-Moonlight vein extends for ~1000 m, covers a vertical interval of at least 400 m, and is up to 25 m in width. The structure forms a dense network of sub-parallel veins that anastomose and branch upward and pinch out at 50–100 m below the current surface. The structure hosts three discrete ore zones, which are approximately 150 m high and about 200 m in length, and which occur in the widest segments of...
