Beyond EPICA: The Game

Tamara Annina Gerber, Nicolas Bienville, Olivier Alemany, Andrea Ceinini et autres

Ice cores are a cornerstone of climate research, offering invaluable data on past atmospheric conditions to help us understand current climate change. The Beyond EPICA project seeks to recover a stratigraphically intact ice core from East Antarctica, capturing a record of atmospheric …

A new Activity Monitor for Aquatic Zooplankter (AMAZE) allows the recording of swimming activity in wild-caught Antarctic krill (Euphausia superba)

Lukas Hüppe, Dominik Bahlburg, Michael Busack, Johannes Lemburg et autres

Antarctic krill (Euphausia superba, hereafter krill) is a pelagic living crustacean and a key species in the Southern Ocean ecosystem. Krill builds up a huge biomass and its synchronized behavioral patterns, such as diel vertical migration (DVM), substantially impact ecosystem structure and …

A conceptual basis for surveying fouling communities at exposed and protected sites at sea: Feasible designs with exchangeable test bodies for in-situ biofouling collection

Wolf Isbert, C. Lindemann, Johannes Lemburg, M. Littmann et autres

The enhanced inertia load caused by biofouling on device components, such as the foundations of wind turbines or other structures at sea, modifies the hydrodynamic properties, and increases the stress to structures, predominantly in upper water layers with high impact from wave …

A dual-tube sampling technique for snowpack studies

Rémi Dallmayr, Johannes Freitag, Maria Hörhold, Thomas Laepple et autres

The validity of any glaciological paleo proxy used to interpret climate records is based on the level of understanding of their transfer from the atmosphere into the ice sheet and their recording in the snowpack. Large spatial noise in snow properties is …

PlasPI marine cameras: Open-source, affordable camera systems for time series marine studies

Autun Purser, Ulrich Hoge, Johannes Lemburg, Yasemin Bodur et autres

Imaging underwater can be particularly problematic and expensive given the harsh environmental conditions posed by salinity and for some deployments, pressure. To counter these difficulties, expensive waterproof pressure resistant housings are often used, commonly built from expensive materials such as titanium, if …
