Volunteer stream monitoring: Do the data quality and monitoring experience support increased community involvement in freshwater decision making?

open access: yesEcology and Society, 2016
Recent freshwater policy reforms in New Zealand promote increased community involvement in freshwater decision making and management. Involving community members in scientific monitoring increases both their knowledge and their ability to discuss this ...

Deep-sea benthic megafauna hotspot shows indication of resilience to impact from massive turbidity flow

open access: yesFrontiers in Marine Science, 2023
Sediment density flows are large scale disturbances that can have dramatic impacts on seafloor animal communities in the deep sea. Seafloor imagery collected in Kaikōura Canyon (New Zealand), before and after a sediment density flow event that included ...

Evaluation of a new method for assessing resilience in urban aquatic social-ecological systems

open access: yesEcology and Society, 2017
Urban aquatic social-ecological systems (SESs) comprise socio-technical elements, the built environment and its management, and natural elements (water bodies) that provide ecosystem services.

Integration of InSAR time series analysis and water vapour correction for mapping postseismic deformation after the 2003 Bam (Iran) Earthquake [PDF]

open access: yes, 2009
Atmospheric water-vapor effects represent a major limitation of interferometric synthetic aperture radar (InSAR) techniques, including InSAR time-series (TS) approaches (e.g., persistent or permanent scatterers and small-baseline subset).

Local Grid Refinement in New Zealand's Earth System Model: Tasman Sea Ocean Circulation Improvements and Super‐Gyre Circulation Implications

open access: yesJournal of Advances in Modeling Earth Systems, 2020
This paper describes the development of New Zealand's Earth System Model (NZESM) and evaluates its performance against its parent model (United Kingdom Earth System Model, UKESM) and observations.

Evolution of observed ozone, trace gases, and meteorological variables over Arrival Heights, Antarctica (77.8°S, 166.7°E) during the 2019 Antarctic stratospheric sudden warming

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2021
We use ground-based spectroscopic remote sensing measurements of the stratospheric trace gases O3, HCl, ClO, BrO, HNO3, NO2, OClO, ClONO2, N2O and HF, along with radiosonde profiles of temperature to track the springtime development of the 2019 ozone ...

Volcaniclastic density currents explain widespread and diverse seafloor impacts of the 2022 Hunga Volcano eruption

open access: yesNature Communications, 2023
The impacts of large terrestrial volcanic eruptions are apparent from satellite monitoring and direct observations. However, more than three quarters of all volcanic outputs worldwide lie submerged beneath the ocean, and the risks they pose to people ...

A consistent molecular hydrogen isotope chemistry scheme based on an independent bond approximation [PDF]

open access: yes, 2009
The isotopic composition of molecular hydrogen (H<sub>2</sub>) produced by photochemical oxidation of methane (CH<sub>4</sub>) and Volatile Organic Compounds (VOCs) is a key quantity in the global isotope budget of (H<sub>2 ...

Assessing Habitat Suitability Models for the Deep Sea: Is Our Ability to Predict the Distributions of Seafloor Fauna Improving?

open access: yesFrontiers in Marine Science, 2021
Methods that predict the distributions of species and habitats by developing statistical relationships between observed occurrences and environmental gradients have become common tools in environmental research, resource management, and conservation. The
