The role of tephras in the NZ-INTIMATE project is a critical one because most high-
resolution palaeoclimatic records are linked and dated by one or more tephra layers. In this …

The term eutrophication broadly refers to the enrichment of aquatic systems by inorganic
plant nutrients (Mason, 1991; Wetzel, 2001). Lake eutrophication occurs when nutrient …

Following resolution of a long-standing debate over the timing of the initial settlement of New
Zealand from Polynesia (late 13th century), a prevailing paradigm has developed that …

The life-span of small volcanoes in terrestrial basaltic fields, commonly considered
'monogenetic', can be difficult to assess due to a paucity of datable materials capable of …

Diatom-based paleolimnological studies are being increasingly used to track anthropogenic
change in estuaries. Little is known, however, about the direction and nature of long-term …

Spectral analyses of quasi-annual organo-diatomaceous laminae couplets in an Auckland
maar lake indicate brief (sub-decadal scale) episodes with strong spectral power and long …

Lake sediment records offer insights into past climate and environmental changes. There
are, however, few continuous lake sediment records from the Southern Hemisphere mid …

Tephra layers are of importance for the construction of reliable age control in late Quaternary
paleoenvironmental and volcanic hazard studies, especially in volcanically-active settings …

A high-resolution record of lacustrine environments spanning ca. 30–9calkaBP was
obtained from Onepoto maar, northern North Island, New Zealand. The multi-proxy record of …

Abstract A continuous, 1,420-cm sediment record from Lake Pupuke, Auckland, New
Zealand (37° S) was analysed for diatom taxonomy, concentration and flux. A New Zealand …
