    Description: A Singular Value Decomposition (SVD) analysis was applied to the 1685-2014 winter series of the four DIs (Mellado-Cano et al. 2019) retaining the two first singular vectors (NAODIs and EADIs), which explain 44% and 35% of the total variance, respectively.

    Reconciling North Atlantic climate modes: Revised monthly indices for the East Atlantic and the Scandinavian patterns beyond the 20th century (2018)
    PANGAEA
    In:  Supplement to: Comas-Bru, Laia; Hernández, Armand (2018): Reconciling North Atlantic climate modes: Revised monthly indices for the East Atlantic and the Scandinavian patterns beyond the 20th century. Earth System Science Data, 10, 2329-2344, https://doi.org/10.5194/essd-10-2329-2018
    Details
    Publication Date: 2023-01-17
    Description: Climate variability in the North Atlantic sector is commonly ascribed to the North Atlantic Oscillation. However, recent studies have shown that taking into account the second and third mode of variability (namely the East Atlantic – EA – and the Scandinavian – SCA – patterns) greatly improves our understanding of their controlling mechanisms, as well as their impact on climate. The most commonly used EA and SCA indices span the period from 1950 to present which is too short, for example, to calibrate palaeoclimate records or assess their variability over multi-decadal scales. To tackle this, here, we make available seasonal (3-months) EOF-based indices of NAO, EA and SCA indices covering the period from 1851 to present (Dataset 2); and compare them with their equivalent instrumental indices calculated as standarised sea-level pressure anomalies from Valentia Observatory, Ireland and Bergen Florida, Norway (Dataset 1)

    Multi-proxy analysis of sediment cores from Lake Azul (Azores archipelago, Portugal) (2021)
    PANGAEA
    Details
    Publication Date: 2023-11-30
    Description: The Azores archipelago is a group of nine oceanic volcanic islands located in the mid-North Atlantic, roughly 1500 km from Europe and 1900 km from America. Lake Azul located in São Miguel island has a surface area of 4.35 km, 28m of maximum depth and is located at 259m above sea level. A coring campaign was conducted in September 2011 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a Core AZ11_02 (1.70 m long) located in the deep basin of the lake (27m depth). The core was dated using ¹⁴C and produced a multi-proxy dataset of geochemical and biological analyses that we used to uncover paleoenvironmental changes on Lake Azul in the last 660 years.

    Publication Date: 2024-01-27
    Description: The Azores archipelago is a group of nine oceanic volcanic islands located in the mid-North Atlantic, roughly 1500 km from Europe and 1900 km from America. Lake Caldeirão is situated in the central caldeira of Corvo Island at 399 m altitude. A coring campaign was conducted in June 2017 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a core (4.60 m long) located in the deepest part of the lake. The core was dated using ¹⁴C and produced a multi-proxy dataset of geochemical and biological analyses that we used to uncover paleoenvironmental changes on Lake Caldeirão in the last 1500 years

    Publication Date: 2024-01-27
    Description: The Azores archipelago is a group of nine oceanic volcanic islands located in the mid-North Atlantic, roughly 1500 km from Europe and 1900 km from America. Lake Funda is situated in the southern sector of the central plateau of Flores Island at 351 m altitude and occupies the bottom of a small maar-explosion crater with 875 m in length and 625 m width, with a total area of 0.37 km2 where several water lines converge. A coring campaign was conducted in June 2017 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a core (9.97 m long) located in the deepest part of the lake. The core was dated using ¹⁴C and produced a multi-proxy dataset of geochemical and biological analyses that we used to uncover paleoenvironmental changes on Lake Azul in the last 1300 years.,
