Our study provides guidelines improving the reuse of marine microfossil assemblage data, which are valuable for understanding past ecosystems and environmental change. Based on a survey of 113 researchers, we identified key data attributes required for effective reuse. Analysis of a selection of datasets available online reveals a gap between the attributes scientists consider essential and the data currently available, highlighting the need for clearer data documentation and sharing practices.

Short summary
A sediment core was analysed, focusing over the 2000 years, in Edisto Inlet. Benthic and planktic foraminifera were picked and used to determine changes in the faunal composition. Using other nearby cores, by comparing different proxies, we were able to identify a succession of three different environmental phases over the studied period: a seasonal-cycle phase (from 2000 to around 1500 years BP), a transitional phase (from 1500 to 700 years BP) and a cold phase (from 700 years to present).

Short summary
This work presents the dataset of continuous monitoring in the southern Adriatic Margin, providing a unique observatory of deep-water dynamics. The study area is influenced by episodic dense-water cascading, which is a fundamental process for water renewal and deep-water dynamics. Information about the frequency and intensity variations of these events is observed along a time series. The monitoring activities are still ongoing and the moorings are part of the EMSO-ERIC network.

Short summary
In the Edisto Inlet, Ross Sea, over the last 3.6 kyr, a marked transition at 2.7–2.5 kyr BP occurred. Geochemical proxies and changes in the foraminiferal community suggest a change from multi-year to seasonal sea ice, likely linked to mCDW (modified Circumpolar Deep Water) intrusion. The study integrates ecological information and geochemical data to unveil connections between mCDW, sea-ice conditions and the SAM (Southern Annular Mode) in Edisto, highlighting it as a key site for regional paleoclimate reconstruction over the Ross Sea.
