Dual Naming of Sea Areas in Modern Atlases and Implications for the East Sea/Sea of Japan Case
Dual naming of sea areas in modern atlases and implications for the East Sea/Sea of Japan case Rainer DORMELS* Dual naming is, to varying extents, present in nearly all atlases. The empirical research in this paper deals with the dual naming of sea areas in about 20 atlases from different nations in the years from 2006 to 2017. Objective, quality, and size of the atlases and the country where the atlases originated from play a key role. All these characteristics of the atlases will be taken into account in the paper. In the cases of dual naming of sea areas, we can, in general, differentiate between: cases where both names are exonyms, cases where both names are endonyms, and cases where one name is an endonym, while the other is an exonym. The goal of this paper is to suggest a typology of dual names of sea areas in different atlases. As it turns out, dual names of sea areas in atlases have different functions, and in many atlases, dual naming is not a singular exception. Dual naming may help the users of atlases to orientate themselves better. Additionally, dual naming allows for providing valuable information to the users. Regarding the naming of the sea between Korea and Japan present study has achieved the following results: the East Sea/Sea of Japan is the sea area, which by far showed the most use of dual naming in the atlases examined, in all cases of dual naming two exonyms were used, even in atlases, which allow dual naming just in very few cases, the East Sea/Sea of Japan is presented with dual naming. -

Biodiversity Data Journal 8: e47183. https://doi.org/10.3897/BDJ.8.e47183 Abstract Background The checklist of Stomatopoda of Greece was developed in the framework of the LifeWatchGreece Research Infrastructure (ESFRI) project, coordinated by the Institute of Marine Biology, Biotechnology and Aquaculture (IMBBC) of the Hellenic Centre for Marine Research (HCMR). The application of the Greek Taxon Information System (GTIS) of this project has been used in order to develop a complete checklist of species recorded from the Greek Seas. The objectives of the present study were to update and cross-check all the stomatopod species that are known to occur in the Greek Seas. Inaccuracies and omissions were also investigated, according to literature and current taxonomic status. New information The up-to-date checklist of Stomatopoda of Greece comprises nine species, classified to eight genera and three families.

Abstract Most hotspots, kimberlites, and large igneous provinces (LIPs) are sourced by plumes that rise from the margins of two large low shear-wave velocity provinces in the lowermost mantle. These thermochemical provinces have likely been quasi-stable for hundreds of millions, perhaps billions of years, and plume heads rise through the mantle in about 30 Myr or less. LIPs provide a direct link between the deep Earth and the atmosphere but environmental consequences depend on both their volumes and the composition of the crustal rocks they are emplaced through. LIP activity can alter the plate tectonic setting by creating and modifying plate boundaries and hence changing the paleogeography and its long-term forcing on climate. Extensive blankets of LIP-lava on the Earth’s surface can also enhance silicate weathering and potentially lead to CO2 drawdown (cooling), but we find no clear relationship between LIPs and post-emplacement variation in atmospheric CO2 proxies on very long (>10 Myrs) time- scales. -

(December 2005) Gabriel Orlando Grimaldi Castro, B.S., Universidad Nacional de Córdoba, Argentina; M.S., Texas A&M University Chair of Advisory Committee: Dr. Steven L. Dorobek Mesozoic tectonic inversion in the Neuquén Basin of west-central Argentina produced two main fault systems: (1) deep faults that affected basement and syn-rift strata where preexisting faults were selectively reactivated during inversion based on their length and (2) shallow faults that affected post-rift and syn-inversion strata. Normal faults formed at high angle to the reactivated half-graben bounding fault as a result of hangingwall expansion and internal deformation as it accommodated to the shape of the curved footwall during oblique inversion. Contraction during inversion was initially accommodated by folding and internal deformation of syn-rift sedimentary wedges, followed by displacement along half-graben bounding faults. -

JOIDES Resolution Expedition 361 (Southern African Climates) Site
IODP Expedition 361: Southern African Climates Site U1475 Summary Background and Objectives Site U1475 is located on the southwestern flank of Agulhas Plateau (41°25.61′S, 25°15.64′E), ~450 nmi south of Port Elizabeth, South Africa, in a water depth of 2669 mbsl. The Agulhas Plateau, which was formed during the early stages of the opening of the South Atlantic about 90 Ma (Parsiegla et al., 2008), is a major bathymetric high that is variably coated with sediments (Uenzelmann Neben, 2001). The 230,000 km2 plateau, which ascends up to ~2500 m above the adjacent seafloor, is bounded on the north by the 4700 m deep Agulhas Passage and is flanked by the Agulhas Basin in the west and the Transkei Basin in the northeast. The northern part of the plateau is characterized by rugged topography, while the central and southern part of the plateau exhibits a relatively smooth topography (Allen and Tucholke, 1981) and has greater sediment thickness (Uenzelmann Neben, 2001). A strong water mass transport flows across the Agulhas Plateau region (Macdonald, 1993), which involves the water column from the surface down to Upper Circumpolar Deep Water. The hydrography of the upper ocean is dominated by the Agulhas Return Current, which comprises the component of the Agulhas Current that is not leaked to the South Atlantic Ocean but rather flows eastwards from the retroflection (Lutjeharms and Ansorge, 2001). Antarctic Intermediate Water, below the Agulhas Return Current, also follows the same flow path near South Africa as the Agulhas Current showing a similar retroflection (Lutjeharms, 1996). -
