The Way

Responding to the way the Southern parts of the Atlantic have historically been obscured in conceptions of the Atlantic world and through the critical oceanic studies concepts of fluidity, solvency, and drift, this chapter serves as a critical introduction to the South Atlantic. Beginning with a rereading of the Atlantic Charter, it poses the South Atlantic both as a material geographic region (something along the lines of a South Atlantic Rim) and as a set of largely unfulfilled visions—including those of anti-imperial solidarity and resistance generated through imaginative and political engagement from different parts of the Global South with the Atlantic world. It also reflects on the conditions under which something called the “Global South Atlantic” could come into being and the modes of historical, cultural, and literary comparison by which a multilingual and multinational region might be grasped.

After loading stores at Göteborg and Oslo, the expedition sailed from London on 23 November 1949 in the chartered Norwegian sealing vessel Norsel, G. Jakobsen, master. After calling at Cape Town, where P. G. Law of the Australian Department of External Affairs and J. A. King of the Union Weather Bureau of South Africa joined the vessel as observers, the Norsel headed south on 27 December to meet the Norwegian whaling factory Thorshovdi, which was carrying an advanced party of five men, with sixty dogs and some heavy equipment. An unexpectedly wide detour had to be made across the South Atlantic as the Thorshevdi was at that time in the Scotia Sea.

In a context of increasing South-South cooperation, the members of an important trilateral dialogue forum that represent the emergent powers – IBSA –, have been incorporated into another organization, BRICS. It resulted from an overlap of the Southern developing countries into the domain of the Euro-Asiatic great powers. Bearing in mind that both alliances are centered on the geostrategic space of the Indian Ocean and the South Atlantic, South Africa´s South Atlantic strategic potential in tandem with Brazil is of extreme importance. It is possible to differentiate two steams in the transatlantic ties: the Afro-Latin and the trans-Mediterranean.  It is also relevant to place the role of Angola in the African continent as a possible influence in South Atlantic´s dynamics, given due importance to the Lusophone ties which are represented by CPLP.

<p>The Atlantic Meridional Overturning Circulation (AMOC), a key component of the Earth's climate system, is sustained through the northward transport of Southern Ocean waters to high latitudes. This returning limb of the AMOC consists largely of relatively cold waters entering from the Pacific Ocean through the Drake Passage, what is commonly referred to as cold-water route. Here, we explore the pathways and transit times of these Antarctic waters that are incorporated to the South Atlantic, with special attention to their recirculation in the subtropical gyre and their escape northward through the North Brazil Current. For this purpose, we use daily values of the climatological GLORYS12v1 velocity field, as obtained using data for 2002-2018 and track the trajectories with the help of the OceanParcels software. We trace the particles transiting through four sections in the Southern and South Atlantic Oceans: 64°W and 27°E, crossing entire Antarctic Circumpolar Current (ACC) through the Drake Passage and off South Africa, respectively; 32°S, from the African coast out to 5°S, sampling the eastern boundary current system; and 21°S, from the American coast out to 30°W, sampling the North Brazil Current.</p><p>Particles are released daily in the Drake Passage down to 1800 m during one full year, its spatial distribution and number being proportional to the transport crossing each vertical portion of the section. This represents an annual-mean of 116.3 Sv entering the Atlantic sector through the Drake Passage, split into 13.3 Sv for surface (Subantarctic Surface Water, SASW, and Subantarctic Mode Water, SAMW), 40.2 Sv for intermediate (Antarctic Surface Water, AASW, and Antarctic Intermediate Water, AAIW) and 62.8 Sv for deep (Upper Circumpolar Deep Water, UCDW) water masses. The particles are then tracked forward, with a one-day resolution, during 20 years. The simulation shows that about 83% of the SASW/SAMW transport follow the ACC past South Africa while the remaining 17% are incorporated to the subtropical gyre. Among the latter, only 13% veer northward and cross the 21°S section. Regarding the intermediate waters, AASW/AAIW, 93% of transport follows the ACC, and 7% join the subtropical gyre. Finally, for the UCDW transport, which remains part of ACC, about 97% follow eastward as the ACC and only 3% drift cross the 32°S section, and only 4% of the latter reach through the 21°S section. The median times for the Drake Passage water particles to get to the 27°E, 32°S and 21°S sections are: 1.7, 2.1 and 5.7 yr for the SASW/SAMW; 2.3, 5.3 and 6.5 yr for the AASW/AAIW; and 3.3, 6.0 and 11.7 yr for the UCDW, respectively. Long tails in the age distributions reflect a high degree of recirculation, being remarkable the high presence of mesoscale eddies around 32°S over Cape Basin.</p>

ABSTRACTThe position of the Falkland Islands adjacent to the South American continental margin belies the close association of their geology with that of South Africa. A Mesoproterozoic basement is unconformably overlain by a Silurian to Devonian succession of fluvial to neritic and shallow marine, siliciclastic strata. This is disconformably succeeded by a largely Permian succession that, near its base, includes a glacigenic diamictite and, thence, passes upwards into a succession of deltaic and lacustrine strata. The lithological succession and the character of its deformation bear striking similarities to the Cape Fold Belt and Karoo retroarc foreland basin. Swarms of Early Jurassic dykes were coeval with the Karoo magmatism and the initial break-up of Gondwana; Early Cretaceous dykes were intruded during the opening of the South Atlantic Ocean. Offshore sedimentary basins surrounding the archipelago contain Late Jurassic to Palaeogene successions and are currently the focus of hydrocarbon exploration. Best known is the North Falkland Basin, a classic failed rift. To the SE, the passive margin, Falkland Plateau Basin may also be rift-controlled, whilst the South Falkland Basin is a foreland basin created at the boundary of the South American and Scotia plates. The role of the Falkland Islands during the breakup of Gondwana remains controversial. Compelling evidence from the onshore geology favours rotation of an independent microplate from an original position adjacent to the Eastern Cape, South Africa. Alternative interpretations, justified largely from offshore geology, favour extension of the Falkland Plateau as a fixed promontory from the South American margin.

Strategic Space

The South Atlantic is becoming a strategic space in terms of development. The sea usage on both shores of the Ocean allows the exploitation and the use, as well as the conservation and the management of the natural resources of the seabed and the subsoil. The guarantee of economic rights, with the counterpart of duties and responsibilities of political nature, environmental and of public security, reflects the possibility of control over and area rich in natural resources and that, at the same time, becomes vulnerable to international pressures of all kinds. The research objectives are: a) analyze the geo-economic importance of the Ocean due the increasing exploitation of this space; b) analyze the new geopolitical reality, because the South Atlantic was converted into a strategic route of passage and development pole; and, c) analyze its geostrategic relevance by establishing a connection with Asia via Indian Ocean, highlighting the role of South Africa and IBSA.
