Imaggeo on Mondays: Indonesian mangroves and tsunamis

Pictured here is a solitary mangrove tree, rooted off the northern coast of the Indonesian island Flores. While this tree has the shallow sandy reef to itself, mangroves are often found clumped together in large forests covering tropical and subtropical coastlines. The propped-up roots of mangrove trees often tangle together, creating a dense natural barrier that can weaken the coastal impact of o ...[Read More]

Back for the first time: measuring change at Narrabeen–Collaroy Beach

Back for the first time: measuring change at Narrabeen–Collaroy Beach

Narrabeen–Collaroy Beach in New South Wales, Australia, just north of Sydney, is home to one of the longest-running shoreline-measurement programmes in the world. With colleagues at the University of New South Wales (UNSW) Sydney, Eli Lazarus, an associate professor in geomorphology at the University of Southampton, UK, has been analysing over 40 years of data from Narrabeen–Collaroy to better und ...[Read More]

Imaggeo on Mondays: Up close and personal with Svalbard glaciers

A University Centre in Svalbard (UNIS) Glaciology student examines the calving front of the Paulabreen glacier [in Spitsbergen, Svalbard], taking advantage of sea ice in the Rindersbukta fjord to safely approach the front. Paulabreen is a surge-type glacier, which means that it periodically switches between long periods of slow, stable flow to short-lived periods of very fast flow during which it ...[Read More]

Imaggeo on Mondays: Simulating a mission on Mars

Establishing a human presence on Mars is increasingly seen by space agencies and private organizations as the horizon frontier in human space exploration. These long-duration missions however, impose a high degree of technological, operational, physical and psychological challenges. Mars analog habitats, such as the Mars Desert Research Station (MDRS) in Utah (U.S.) are established to conduct fiel ...[Read More]
