Short summary
Short summary
This study shows a new method for mapping coralligenous bioconstructions using high-resolution acoustic data. The protocol integrates bathymetry, backscatter, and geomorphological indices, providing detailed information on the spatial and volumetric distribution of benthic habitats. This approach offers valuable insights for monitoring and conserving Mediterranean ecosystems, with potential applications in understanding habitat structure and guiding future conservation actions.

Who constructs the build-ups of the Mediterranean Sea? What is the role of skeletal and soft-bodied organisms in these bioconstructions? Do bacteria play a role in their formation? In this research, for the first time, the coralligenous of the Mediterranean shelf is studied from a geobiological point of view with an interdisciplinary biological and geological approach, highlighting important biotic relationships that can be used in interpreting the fossil build-up systems.

The coralline alga Lithothamnion corallioides is widely distributed in the Mediterranean Sea and NE Atlantic Ocean, where it constitutes rhodolith beds, which are diversity-rich ecosystems on the seabed. The boron incorporated in the calcified thallus of coralline algae (B/Ca) can be used to trace past changes in seawater carbonate and pH. This paper suggests a non-negligible effect of algal growth rate on B/Ca, recommending caution in adopting this proxy for paleoenvironmental reconstructions.

Ocean liming is a technique proposed to mitigate ocean acidification. Every action we take has an impact on the environment and the effects on the invisible world are often overlooked. With this study, we show that lime addition impacts the dynamics of dissolved organic matter, one of the largest reservoirs of carbon on Earth, representing the main source of energy for marine microbes. Further studies to assess the impacts on marine ecosystems are therefore crucial before taking any action.

This paper provides comprehensive guidelines for ocean alkalinity enhancement (OAE) researchers on archiving their metadata and data. It includes data standards for various OAE studies and a universal metadata template. Controlled vocabularies for terms like alkalinization methods are included. These guidelines also apply to ocean acidification data.

Mesocosm experiments represent a highly valuable tool in determining the safe operating space of ocean alkalinity enhancement (OAE) applications. By combining realism and biological complexity with controllability and replication, they provide an ideal OAE test bed and a critical stepping stone towards field applications. Mesocosm approaches can also be helpful in testing the efficacy, efficiency and permanence of OAE applications.

Planktonic gastropods (pteropods and heteropods) have been investigated in cores collected in the eastern Mediterranean along the Israeli coast in coral, pockmark, and channel areas. The sediment spans the last 5300 years. Our study reveals that neglecting the smaller fraction (> 63 µm) may result in a misinterpretation of the palaeoceanography. The presence of tropical and subtropical species reveals that the eastern Mediterranean acted as a refugium for these organisms.

Short summary
Ultrastructures of Lithothamnion corallioides, a crustose coralline alga collected from the Atlantic and Mediterranean Sea at different depths, show high-Mg-calcite cell walls formed by crystals with a specific shape and orientation that are unaffected by different environmental conditions of the living sites. This suggests that the biomineralization process is biologically controlled in coralline algae and can have interesting applications in paleontology.
