Crowd solutions to challenges in Earth Sciences

Research rarely follows a straight path and it is normal for challenges to arise during a scientific career. These challenges may come from scientific issues, like inaccessible field sites or data or unavailable/insufficient methods, or from social or personal problems and so on. This year we are facing an additional problem in our inability to meet in person, travel and go to the field. As we all ...[Read More]

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 Zealand.   Description by Pontus Lurcock, af ...[Read More]
