Fig. 8 in A low diversity shallow water lingulid brachiopod-gastropod association from the Upper Ordovician of Kyrgyz Range

Fig. 8. Palaeogeographic reconstruction for the Late Ordovician (early Caradocian) showing geographical destribution of shallow water (BA1) lingulid−mollusc associations on Kazakh terranes. The reversed position of the North China plate in low northern latitudes and position of Tarim plate at 36.5°S are mainly after Zhao et al. (1996). Relative positions of Gondwana, Armorica, Baltica, Avalonia, and Laurentia are mainly after Torsvik (1998). Kazakhstan in the Ordovician was not a single plate but an assemblage of island arcs and microplates (Apollonov 2000; Webby et al. 2000). Some Kazakh terranes (Chingiz−Tarbagatai) are remnants of several Early Palaeozoic intra−oceanic island arcs, in a part possibly representing the Cambrian eastern active margin of Baltica detached sometime within the Late Cambrian–Early Ordovician. Another group of Kazakh terranes (North Tien Shan, Chu−Ili, Balkhash−Dzhungaria, Ulutau−Karatau−Naryn) are microplates presumably of a peri−Gondwanan origin. Position of North Tien−Shan at low southern latitudes after Bazhenov et al. (2003).

manuscript (atmosphere-3145955) titled: The Black Sea Upwelling System: Analysis on the Western Shallow Waters Authored by: Maria Emanuela Mihailov was accepted in Atmosphere (ISSN 2073-4433) on 15 August 2024

Datasets represents the modelling results for: - Coastal Upwelling Transport Index (CUTI) of the National Oceanic and Administrative Administration’s Environmental Research Division (NOAA-ERD) was used to derive the time series of the coastal upwelling index in four locations on the north-western Black Sea coast. The coastal upwelling index time series was calculated using monthly average wind fields from the European Centre for Medium-Range Weather Forecasts (ECMWFs) reanalysis and MATLAB software to compute the CUTI   - The upwelling index (UI) is computed using the CUTI Formula (Bakun Index ), defined as CUTI (m3·s−1·100 m−1), representing the volume transport per distance unit of an alongshore section. The sign of Ekman transport is changed to define positive or negative values of UI as a response to upwelling or downwelling favourable winds. To compute the BEUTI, Copernicus Marine Service [1] data are used for dedicated locations. [1] Grégoire, M.; Vandenbulcke, L.; Capet, A.
