Imaggeo On Monday: The tree that gave birth to a forest
This 10 centimetre giant is a pioneer of marine conquest. All summer, glassworts (Salicornia europaea) will be rhythmically swept by the tide, gradually trapping seaborne sediment on the shores of Aberlady Bay in Scotland. The resulting elevation of the mudflat marks the start of a race of growth against waves, currents and sea level rise, …[Read More]
Imaggeo On Monday: A drift of sea-snail shells
A collection of washed-up shells on a beach on the south island of New Zealand. Shore transport processes have produced a well-sorted drift of similarly sized (approx. 1-2 cm) shells and shell fragments. The main species represented are the common turret shell (Maoricolpus roseus) and wheel shell (Zethalia zelandica), both sea snails endemic to New …[Read More]
Pride on board: working on an ocean-going research vessel as an LGBTQI+ person

Pride month is another great opportunity for reflection and to consider how things have changed for us …[Read More]
Imaggeo On Monday: Giant Australian Cuttlefish in the Spencer Gulf, South Australia
In the shadow of the Santos oil and gas processing plant and export terminal lies the only place in the world where cuttlefish come together by the tens of thousands to mate every winter. The unique geology of the area, with a seafloor composed of bedrock and tabular quartzite blocks, makes for an ideal egg-laying …[Read More]
Imaggeo On Monday: Studying shell morphodynamics to improve climate models
Profile of a specimen of Arctica islandica, one of the longest lived marine bivalves known, undergoing a 3D scan. Their longevity is exploited for reconstruction of climate patterns in the North Atlantic. However, mathematical models of their morphodynamics are necessary to account for bias induced by their asymmetric growth (“morphodynamics” is the study of how …[Read More]

Imaggeo On Monday: The kidneys of the Planet
In the past, humans considered wetlands as morbid environments where it was difficult, if not impossible, to live. Wetlands, instead, are vital to the health of wildlife and humans, as the Ramsar convention stated in 1971. Wetlands regulate the water flow, buffering droughts as well as floods, and also contribute to the provision of clean …[Read More]
Don’t leaf it to the trees: Amazonian soils also work to store carbon.
The Amazon rainforest covers an area of 5.5 million km² and is well known for being an invaluable global resource for carbon storage. But it’s not just the trees and vegetation of the Amazonian rainforest that lock in and store carbon – the very soil in these forests can do the same thing, according to …[Read More]
Imaggeo On Monday: The veins of the living planet
Today’s imaggeo on Monday provides us with a space to reflect on the interconnected nature of our planet’s systems. The photographer, Antonello Provenzale, wrote of this image: Earth is a living planet, where the water cycle plays an essential role. A waterfall in the mountains of Valle Pesio, Italy, in a landscape of vegetation and …[Read More]
