Journal ArticleDOI
Sediment yield and impacts from river catchments to the Great Barrier Reef lagoon
TL;DR: In this article, it was shown that croplands cause the greatest increase of sediment yield and sediment concentration, whereas erosion of grazing land is the main contemporary source of sediments, primarily owing to the large spatial extent of this land use.
Journal ArticleDOI
Temporal variation of light availability in coastal benthic habitats: Effects of clouds, turbidity, and tides
TL;DR: This article analyzed the contributions of clouds, turbidity, and tides to variations in irradiance and predicted benthic primary productivity on a coastal coral reef over a period of 2 yr (2001-2002).
Journal ArticleDOI
From Oblique Subduction to Intra-Continental Transpression: Structures of the Southern Kermadec-Hikurangi Margin from Multibeam Bathymetry, Side-Scan Sonar and Seismic Reflection

TL;DR: In this paper, the authors provide evidence that faulting with a significant strike-slip component is widespread along the entire 1000 km margin of the southern Kermadec-Hikurangi convergent margin.
Journal ArticleDOI
Earthquakes drive large-scale submarine canyon development and sediment supply to deep-ocean basins.

TL;DR: It is demonstrated that earthquake-triggered canyon flushing is a primary driver of submarine canyon development and material transfer from active continental margins to the deep ocean.
Journal ArticleDOI
Natural turbidity variability and weather forecasts in risk management of anthropogenic sediment discharge near sensitive environments.
Alan R. Orpin,Peter V. Ridd,Severine Thomas,Severine Thomas,Kenneth R. N. Anthony,Paul Marshall,Jamie Oliver +6 more
TL;DR: This study characterises the spatial and temporal variability of turbidity near an inshore fringing coral reef in the central Great Barrier Reef, under a wide range of natural conditions and outlines a risk management scheme to minimise the impact of construction-related turbidity increases.
