Changes in water mass composition and circulation in the central Arctic Ocean between 2011 and 2021 inferred from tracer observations [PDF]
The Arctic Ocean is changing rapidly and Atlantic Water circulation plays a key role in the warming, sea-ice decline, and ecosystem changes observed in the Arctic.

Global variation of seismic energy release with oceanic lithosphere age
Variations in Mid Ocean Ridge seismicity with age provide a new tool to understand the thermal evolution of the oceanic lithosphere. The sum of seismic energy released by earthquakes during a time, and for an area, is proportional to its lithospheric age.

Magma genesis by rifting of oceanic lithosphere above anomalous mantle: Terceira Rift, Azores [PDF]
[1] The Terceira Rift formed relatively recently (∼1 Ma ago) by rifting of the old oceanic lithosphere of the Azores Plateau and is currently spreading at a rate of 2–4mm/a.

Patterns of Life on the Southern Mid-Atlantic Ridge: Compiling What is Known and Addressing Future Research [PDF]
The South Atlantic is one of the youngest of all the major oceans. It has prominent topographic features, in particular, the Mid-Atlantic Ridge. This feature largely determines deepwater circulation patterns that connect this ocean to the North Atlantic,

On some rare Oplophoridae (Caridea, Decapoda) from the South Mid-Atlantic Ridge
The Mid-Atlantic Ridge (MAR) divides the Atlantic Ocean longitudinally into two halves, each with a series of major basins delimited by secondary, more or less transverse ridges.

Bottom water renewal on the western flank of the mid-Atlantic Ridge is driven by rapid intrusion of cold, dense water enabled by gradual warming due to geothermal heat flux and diapycnal mixing, as revealed by six-year observational records.

Nonchondritic 142Nd in suboceanic mantle peridotites [PDF]
The discovery that several solid Earth reservoirs have a superchondritic 142Nd/144Nd ratio led to the hypothesis that either the bulk silicate Earth is not chondritic or that a subchondritic reservoir lies hidden somewhere within the Earth's interior ...

New records of two teleost species from two insular areas of the western equatorial Atlantic [PDF]
We report the first record of two teleost species from two archipelagos in the western equatorial Atlantic. We recorded the occurrence of Cantherhines pullus (Ranzani, 1842) (Monacanthidae, Tetraodontiformes) from the Fernando de Noronha Archipelago, a ...

Endemic Hydrothermal Species Anisopes heteroscella (Ammotheidae, Pycnogonida) in the Northern Part of the Atlantic Ocean [PDF]
Expeditions of R/V «Akademik Mstislav Keldysh» and R/V «Pourquoi Pas» were collected 61 specimens of endemic hydrothermal species Anisopes heteroscella (Child, Segonzac, 1996). The specimens were collected at the six hydrothermal vents.

Oceanographic and underwater acoustics research conducted during the period 1 May 1961-31 October 1961 [PDF]
Research during this six month period was performed during cruises of the CHAIN to the Romanche Trench, to the Puerto Rico Trench, and to the Mediterranean Sea, and during a cruise of the BEAR to the Gulf of Maine.
