<p>The marine boundary layer offers a unique opportunity to investigate the electrical properties of the atmosphere, as the effect of natural radioactivity in driving near surface ionization is significantly reduced over the ocean, and the concentration of aerosols is also typically lower than over land. This work addresses the temporal variability of the atmospheric electric field in the South Atlantic marine boundary layer based on measurements from the SAIL (Space-Atmosphere-Ocean Interactions in the marine boundary Layer) project. The SAIL monitoring campaign took place on board the Portuguese navy tall ship NRP Sagres during its circumnavigation expedition in 2020.  Two identical field mills (CS110, Campbell Scientific) were installed on the same mast but at different heights (about 5 and 22 meters), recording the atmospheric electric field every 1-second. Hourly averages of the atmospheric electric field are analyzed for the ship’s leg from 3<sup>rd</sup> to 25<sup>th</sup> March, between Buenos Aires (South America) and Cape Town (South Africa). The median daily curve of the electric field has a shape compatible with the Carnegie curve, but significant variability is found in the daily pattern of individual days, with only about 30% of the days exhibiting a diurnal pattern consistent with the Carnegie curve.</p>

The most widely-accepted views of the origins of the South Atlantic War contend that it arose either out of the Argentine junta's need to divert attention away from a worsening economy or from misperceptions in both London and Buenos Aires. This article argues that the ‘demobilisation’ of Argentine civil society removed the need for a diversionary war; and that the lengthy crisis bargaining that followed in the wake of the ‘grab’ of the Falklands/Malvinas Islands substantially mitigated the impact of any misperceptions. This article advances an alternative to existing theories that explains the outbreak of this war by reference to both structural and organisational factors. A fast decreasing gap in relative power between Argentina and Britain may have encouraged the junta more seriously to consider the possibility of initiating a war between the two. Thereafter, however, the organisational pathologies of the Argentine military led to a suboptimally timed preemptive invasion, intransigent diplomacy and a ‘hedged’ approach to deployments that severely undermined Argentina's military effectiveness, allowing Britain to undertake reconquest of the islands with a very reasonable chance of success.


The palaeomagnetism of Ordovician and Devonian and Carboniferous sedimentary rock formations exposed in Bolivia has been studied. It is deduced that the south palaeomagnetic pole was situated in the Guianas in the Middle Palaeozoic, and in the south Atlantic, about half way between the present positions of Buenos Aires and Cape Town in the Carboniferous.

Hold hard. Ten years on, the second wave is about to break. The ultimate Channel 4 documentary series is already in the can. It seems that the tributary of personal reminiscence from high and low (but chiefly high) has not run dry after all Recollected in tranquillity, it turns turbulent once more—as witness the fascinating collective testimony elicited by Michael Charlton in The Little Platoon (1989), at once pointer and landmark for the new wave. Already we have the Carrington memoirs, the Whitelaw memoirs, and even that most unlikely artefact, the Tebbit memoirs. From Washington come the Haig memoirs and the Weinberger memoirs, not to mention a shoal of smaller fry. Our man in Buenos Aires author of a prophetic complaint about the typical British approach to the Falklands, that is, ‘to have no strategy at all beyond a general Micawberism’ talked at length to Michael Charlton and to Peter Kosminsky (for the excellent Yorkshire TV documentary ‘Falklands—The Untold Story’). Our men in Washington and at the UN, both writers of distinction, have published revealing accounts of their stewardships. These British accounts can now be matched against the waspish reflections of Jeane Kirkpatrick, the dissentient US Representative at the UN, an exercise full of interpersonal and international interest. The generals and admirals of each side continue to be remarkably forthcoming, in one case from prison, in the other from retirement—such are the spoils of war.

The creation of the Zone of Peace and Cooperation of the South Atlantic (ZPCSA) in 1986 and the Gulf of Guinea Commission (GGC) in 2001 was about changes in the distribution of world power. This article argues that though they emerged at different times, their strategic orientation converges in a number of areas related to the significant interests in the South Atlantic as an area of stability in the region to be marked by strong political, economic and military ties. They also converge on the ideal for development, security and greater projection of power and influence in international affairs. The South Atlantic being a route of passage and trade, as a means of access and flow of energy products, the region became a site for new calculations of regional strategic powers about world affairs. The article also argues that ZPCSA and GGC are therefore crucial for the regional order and the development of higher capacities for cooperation on strategic issues. The actual point of convergence extends to ensuring the sovereignty through dialogue between the states in the region that are involved.

North and South Atlantic lateral volume exchange is a key component of the Atlantic Meridional Overturning Circulation (AMOC) embedded in Earth’s climate. Northward AMOC heat transport within this exchange mitigates the large heat loss to the atmosphere in the northern North Atlantic. Because of inadequate climate data, observational basin-scale studies of net interbasin exchange between the North and South Atlantic have been limited. Here ten independent climate datasets, five satellite-derived and five analyses, are synthesized to show that North and South Atlantic climatological net lateral volume exchange is partitioned into two seasonal regimes. From late-May to late-November, net lateral volume flux is from the North to the South Atlantic; whereas from late-November to late-May, net lateral volume flux is from the South to the North Atlantic. This climatological characterization offers a framework for assessing seasonal variations in these basins and provides a constraint for climate models that simulate AMOC dynamics.
