    Description: The Mediterranean region is expected to be highly impacted by global warming. To better understand and predict shifts in its current climate system, climate time series covering seasonal-to-century scale climate variability are needed. Here we provide a dataset containing a high-resolution reconstruction of autumn precipitation variability for the Central Pyrenees that spans the 1500-2002 CE period. This dataset is based on calcite sublayer width of varved sediments of lake Montcortès. Sediment cores MON12-3A-1G and MON12-2A-1G were retrieved from the deepest basin of the lake. Large-scale thin sections of sediment (120 mm X 35 mm) were extracted and calcite varve sublaminae counted and characterised. The age-depth model was built by combining varve counting and radiometric dating (210Pb, 137Cs and 14C). Long-term trend of the raw calcite width series was removed with a low pass filter by fitting a cubic smoothing spline of 67% of the series length. To find out how well the smoothed calcite series and instrumental regional precipitation match up with each other, correlation and cross correlation methods were applied. Highest correlation values were obtained with autumn precipitation anomalies for the entire calibration period (1900-2002) and for the two halve subperiods (1910–1956 and 1957–2002). The applied statistical tests yield highly significant results. The obtained regression model explained 15.5% (R2-value for the full calibration period) of the September to November precipitation variability. The obtained transfer function allowed inferring past autumn precipitation from calcium carbonate sublayer thickness at annual resolution. The reconstructed series (PPT-SON) provides the first estimations of regional autumn precipitation shifts in the Central Pyrenees since 1500 CE.

    Description: This study is the first integrated assessment of the main oceanographic features of the Beagle Channel, using data from several oceanographic cruises and a mooring. This dataset derives from an oceanographic mooring installed in the center of the Beagle Channel close to Yendegaia bay. This mooring included hourly temperature measurements at 50 m and 195 m between 21 July 2017 and 28 September 2019, while temperature at 100 m was recorded from 21 July 2017 to 19 July 2018 only. The study was funded by the IDEAL center (Research Center: Dynamics of High Latitude Marine Ecosystems, https://www.centroideal.cl/, award: FONDAP 15150003).

    Description: This study is the first integrated assessment of the main oceanographic features of the Beagle Channel, using data from several oceanographic cruises conducted between 19-25 October 2016, 19-26 July 2017 and 18-23 July 2018 by the IDEAL center (Research Center: Dynamics of High Latitude Marine Ecosystems). During 2016 transects were done between the NW entrance of the Beagle Channel up to Yendegaia bay (mid of the channel). In winter 2017, simultaneous to the IDEAL transect, a full oceanographic survey onboard M/O Bernardo Houssay (PNA, Argentina) by researchers of CADIC (Austral Center for Scientific Research in Ushuaia) was conducted from nearby Yendegaia bay to the eastern limit of the Beagle Channel (27-30 August 2017), thus closing for the first time a full, high resolution, hydrographic section along the entire Channel. During 18-23 July 2018 the NW branch and the SW branch of the Beagle Channel was surveyed. The study was funded by the IDEAL center (https://www.centroideal.cl/, award: FONDAP 15150003).
