4Dlandscapes is a blog about glacial, periglacial, coastal, volcanic, aeolian and planetary geomorphology and its place in time by Timothy Barrows, Professor of Environmental Change at the University of Portsmouth and Principal Fellow at the University of Wollongong.

Tim is a scientist specialising in understanding landscapes through the use of geomorphology and geochronology. He uses extremely rare radioactive elements known as cosmogenic nuclides to determine the age of landforms and the rates of processes shaping the landscape. 3D modelling provides a means to visualise dated landforms, model their formation and to understand their processes of development. He also develops techniques to quantify climate change over geological timescales from glaciers, oceans and lakes. Tim has conducted field work in Australia, New Zealand, Papua New Guinea, Lesotho, South Africa, Ethiopia, Sudan, Spain, USA, UK, Svalbard, Greenland, Nepal and is a regular in Iceland.
