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,

When tiny convective spread affects a midlatitude jet: Spread sequence
We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

The Prediction, Verification, and Significance of Flank Jets at Mid-Ocean Ridges [PDF]
One aspect of ocean flow over mid-ocean ridges that has escaped much attention is the capacity of a ridge to convert oscillatory flows into unidirectional flows.

October 2019 was characterized by three main multiday wet spells in Bafoussam and Dschang. Our results indicated that wet spells were influenced by a vortex pair near the Gulf of Guinea, a strong Sahara Heat Low located anomalously far east and north, a northward shift of the intertropical discontinuity, an enhancement of the inland penetration of the ...

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.

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach
This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

Lava Geochemistry as a Probe into Crustal Formation at the East Pacific Rise [PDF]
Basalt lavas comprise the greatest volume of volcanic rocks on Earth, and most of them erupt along the world's mid-ocean ridges (MORs). These MOR basalts (MORBs) are generally thought to be relatively homogeneous in composition over large segments of the

Near-seafloor magnetic mapping of off-axis lava flows near the Kairei and Yokoniwa hydrothermal vent fields in the Central Indian Ridge [PDF]
The Kairei (KHF) and Yokoniwa hydrothermal fields (YHF) are hosted in mafic as well as ultramafic rocks distributed at an off-axis volcanic knoll of the Central Indian Ridge.

We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

Ocean bottom seismic model in the Knipovich Ridge area [PDF]
The structure of the oceanic crust generated by the ultraslow-spreading mid-ocean Knipovich Ridge still remains relatively uninvestigated compared to the other North Atlantic spreading ridges further south. The complexity of the Knipovich Ridge, with its
