Ecological succession on 3D printed ceramic artificial reefs.

The global degradation of natural coral reefs requires innovative approaches to their conservation and restoration. This study investigates the efficacy of using parametric design tools in 3D software and 3D-printed terracotta structures in artificial reef (AR) design. Three ARs were deployed in the northern Gulf of Aqaba in 2019.

The daily resolved temperature dependence and structure of planktonic foraminifera blooms.

Planktonic foraminifera (PF) life cycles are highly sensitive to marine conditions, which are evolving rapidly due to anthropogenic climate change. Even though PF shells in the sedimentary record serve as prominent proxies of past ocean conditions, very little is still known about their life cycles, particularly in oligotrophic environments. Here, we present a full annual record of PF fluxes (> 63 µm) from the oligotrophic Gulf of Aqaba, northern Red Sea, sampled at daily timescales during 2015-2016 using an automated time-series sediment trap.
