The Dead Sea Deep Drilling Project allowed to retrieve a continuous sedimentary record spanning the two last glacial cycles. This unique archive, in such an extreme environment, has allowed for the development of new proxies and the refinement of already available paleoenvironmental studies. In particular, the interaction of the lake and sediment biosphere with elements and minerals that [...]

Laminated microbial mats and microbialites are documented from a variety of coastal marine environments. These features form through: a) the combination of trapping and binding of allochthonous grains, and b) microbially-mediated or controlled precipitation of a variety of minerals, including high-magnesium calcite and dolomite. Intertidal pools and associated microbial features have been [...]
