The diversity of scales and modes in which ground, airborne and spaceborne LiDAR operate has increased opportunities for quantitatively assessing forest structure, biomass and species composition and obtaining more general ...

Ground-penetrating radar and luminescence dating studies of a large, complex, linear dune in the northern part of the Namib Sand Sea provide new information on the age and internal sedimentary structures of these dunes, ...

With the successful launch of Japan's Advanced Land Observing Satellite (ALOS) Phased Array L-band SAR (PALSAR) and the recent provision of a Japanese Earth Resources Satellite (JERS-1) Synthetic Aperture Radar (SAR) mosaic ...

Two modern coastal sands are studied through single-grain optical dating techniques. The first sample is estimated to be less than 10 y old by means of independent age control and is known to be well-bleached on the basis ...

The fading rates (g-values) of various luminescence signals were measured using four samples of basalt. It appeared that the fading rates measured by optically stimulated luminescence (OSL) detected in the UV, and ...

In quantifying the carbon budget of the Amazon region, temporal estimates of the extent and age of regenerating tropical forests are fundamental. However, retrieving such information from re mote-sensing data is difficult, ...

Prior to and since European settlement, humans have impacted on the vegetation of Queensland, Australia, primarily by changing fire regimes and clearing forests for agriculture but also by introducing flora and fauna. Such ...

The possibility of dating basalt using luminescence was tested on four samples with independent age control from Cima volcanic field, California, with the ultimate aim of assessing whether the technique could be used to ...

Optical dating is increasingly being applied to fluvial deposits to derive rates of geomorphological and sedimentary processes. Partial bleaching of the water-transported sediment grains is a common occurrence, however, ...

Human activities have doubled the pre-Industrial supply of reactive nitrogen on Earth, and future rates of increase are expected to accelerate. Yet, little is known about the capacity of the biosphere to buffer elevated ...
