Mediterranean sapropels represent an exceptional example of productivity fluctuations reconstructed from Ba proxies. They have been cyclically deposited in the Mediterranean by the combination of climatically induced increases in primary productivity

Dust deposition can trigger phytoplankton growth in oligotrophic low nutrient low chlorophyl (LNLC) regions by providing essential nutrients to the surface ocean. As LNLC regions comprise 60% of the global ocean, dust fertilisation and potential subs

The mid/far infrared hosts a wealth of spectral information that allows direct determination of the physical state of matter in a large variety of astronomical objects, unhindered by foreground obscuration. Accessing this domain is essential for astr
