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.

We present a unique dataset of underwater measurements collected by an autonomous glider in the western Mediterranean Sea. It reveals how ocean layers mix over seasons and years. Using sensors to detect small scale water movements, we estimated how energy and heat are transferred in the ocean. These data help scientists better understand ocean circulation and climate effects. All files and methods are openly shared to support future research.

Having consistent dissolved Oxygen (O2) data is crucial for understanding the health of our oceans. By monitoring O2 levels, we can spot changes in water quality. Reliable data helps scientist and policymakers make informed decisions to protect marine environments, ensuring practices that benefit both wildlife and people. The Mediterranean Sea is particularly sensitive to climate change. O2WMED dataset- a compilation of data that provides a clear picture of O2 changes over the past 20 years. 

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).

This paper presents the results of the first 2 years of the Levante Canyon Mooring, a mooring line placed since 2020 in the eastern Ligurian Sea, to study a canyon area at about 600 m depth characterized by the presence of cold-water living corals. It provides hydrodynamic and thermohaline measurements along the water column, describing a water-mass distribution coherent with previous evidence in the Ligurian Sea. The data also show a Northern Current episodic and local reversal during summer.
