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]

Imaggeo on Mondays: Penguins – a biogeochemical link between sea and land

A couple of Chinstrap penguins (Pygoscelis antarctica) at their nesting site on Deception Island, maritime Antarctica. Sea birds contribute importantly to biogeochemical cycles in coastal ecosystems and on islands. Feeding on the marine food chain and nesting on land, they carry large amounts of marine nutrients into terrestrial ecosystems. This might be of particular importance for the nitrogen ( ...[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]
