title: Mineral composition of samples from sediment cores from cruise HU90023

description: Samples from six piston cores from cruise HU90023-030, -031, -034, -045, 099 and 101 (MacLean, 1991) were processed to provide information of the source(s) of Hudson Strait Heinrich sediments in the Labrador Sea. The cores are located in terms of latitude, longitude, water depth, and the regional name for each site (MacLean, 2001a). Radiocarbon dates on the cores are listed in MacLean (ed) (2001) and in (Manley and Jennings, 1996).

title: Till and glaciomarine surface sediments of Hudson Strait

description: Till and glaciomarine sediments: Samples of till and glaciomarine sediments collected above present sea level were analyzed from three areas of Hudson Strait. The latitude and longitude for the sites are included, if known. Samples from the outer NE coast of Hudson Strait (coast of SE Baffin Island) were collected by Miller (Miller, 1980; Miller et al., 1988). Till and glaciomarine samples from the central northern Hudson Strait coast (Big Island) were collected by Manley (Manley, 1995; Manley, 1996). Finally, till samples from Akpatok Island and the Labrador Trough were provided by Dr J.T. Gray (Gray, 2001; Gray and Lauriol, 1985). Where possible the sites are identified by their latitude and longitude but for several this information was lost during building moves.

title: Reconstructed upper ocean temperature (UK'37 and TEXH86) of sediment core GL-1180, western tropical Atlantic

description: During glacial terminations, the role of cross-equatorial currents in the northward spreading of warm and salty waters is essential to the reach of the following interglacial state. In the western tropical Atlantic, where the interhemispheric North Brazil current develops, most of the existing temperature records focused on the last deglaciation. Here, using a marine sediment core covering the last 305 kyr before present (BP), we present two records of the surface (mixed layer) and the subsurface (upper thermocline) temperatures based on organic proxies UK'37 and TEXH86 respectively. During the last three glacial terminations, these records exhibit large temperature increases especially in the subsurface layer. We suggest the combined influence of the thermal bipolar seesaw and the Agulhas Leakage, acting together to warm the interior South Atlantic, to explain the strong warming of the tropical western Atlantic thermocline (+ 5°C) during these periods of reduced AMOC. In addition, we propose an enhanced cross-equatorial gyre to elucidate the synchronous deglacial warming of the western and eastern sides of the tropical Atlantic. The resumption of the AMOC at the onset of the following interglacial leads to the release of heat stored in thermocline waters mainly in the whole South Atlantic, as highlighted by the sharp upper ocean cooling recorded at the end of the deglacial interval. The combination of this temperature record and previously published ones in the western tropical Atlantic confirms the strong sensitivity of the upper ocean to AMOC changes in this region.

title: Raw values of boundary layer O3 measurements at Neumayer III station, Antarctica from January 2016 to August 2018

description: From January 2016 until August 2018, an automated Long-Path Differential Optical Absorption Spectroscopy (LP-DOAS) instrument was operated at the German research station Neumayer III (NMIII) in coastal Antarctica to measure trace gas mixing ratios in the boundary layer close to the ground (average altitude above the snow surface: 4m). An atmospheric light path with a total length of 3100 m was used.The DOAS evaluation of O3 was performed between 286.5 and 329.5 nm. Fits with residual optical density RMS (root mean square) values larger than 4.0e-4 were discarded. The resulting mean residual RMS is 1.9e-4. The mean detection limit is 0.8 nmol/mol.The data sets include the observations below the respective detection limit scattered around 0, which due to the spectral analysis with the DOAS approach can include negative values. Significant data points can be selected using the separately provided detection limits (3-sigma criterion - recommended). Alternatively, the total errors can be used.The mixing ratios provided here were calculated using meteorological data from Neumayer III station already published on PANGAEA. A list of data sets is included in the "Related to" section of the bibliography this data set is part of.The spectral raw data of the measurements is stored on the measurement data server of the Institute of Environmental Physics, University of Heidelberg.

title: Homogeneous daily solar (GLOBAL) radiation data for station Piła (Poland) for the period 1991-2015

description: Ground-based measurements of global solar radiation are often subject to various errors which are very difficult to detect. This is why quality control procedures and homogenisation of data are essential and should be performed prior to further analyses. We present homogeneous global solar radiation data set, without any gaps, for 16 ground-based stations located in Poland for the period 1991-2015. The data set was prepared with a modification of bias-based quality control (BQC) method (developed by Urraca, and presented in 2017), tailored specially for detecting single erroneous daily values (mostly caused by a failure of the measuring equipment), and very long periods of small errors (mostly caused by a miscalibration of the measuring equipment). The values on the days considered as erroneous were replaced with debiased SIS SARAH-2 values. In many situations the data were visually checked to make sure that the prepared set constitutes the best possible climatology of actinometric data in Poland.

title: Annual Time Series of Air Temperature, Precipitation, and Urban Area Extent in Modena, Italy - Table

description: An uninterrupted data set of 139 annual values of local mean air temperature T, cumulative precipitation depth P, urban area extent A, global mean surface air temperature G, and global CO2 concentration C for the 1881-2019 period of time is shared with the scientific community. The annual time series of T and P are obtained from daily observations collected at the Geophysical Observatory of the University of Modena and Reggio Emilia (latitude 44.6474°N, longitude 10.9293°E, elevation 76.50 m asl), Modena, Italy. Observations of A for the town of Modena are available for years 1881, 1940, 1961, 1971, 1981, 1998, 2000, and 2002–2019. Cubic spline interpolation is applied to obtain reconstructed values of A for the other years in the 1881-2019 period of time. The annual time series of G is obtained by adding the NASA GISTEMP temperature change to the average temperature observed in Modena in the 1951–1980 base period so that it can be meaningfully compared to the observed local temperature T (https://data.giss.nasa.gov/gistemp/). Global CO2 concentration C estimated from ice cores, from 1881 to 1958 (https://cdiac.ess-dive.lbl.gov/trends/co2/lawdome-data.html), and observed in the Mauna Loa Observatory (latitude 19.5362°N, longitude 155.5763°W, elevation 3397.00 m asl), Hawaii, from 1959 to 2019 (https://gml.noaa.gov/ccgg/trends/data.html), are combined to provide the annual time series of C for the 1881-2019 period of time.
description: This dataset has been created from ASCII file "ts.dat" of dataset doi:10.1594/PANGAEA.938737.The first column contains the year.The second column contains the local mean air temperature T in Celsius degrees observed in Modena.The third column contains the cumulative precipitation depth P in millimeters in Modena.The fourth column contains the urban area extent A in square kilometers of Modena.The fifth column contains the global mean surface air temperature G in Celsius degrees obtained by adding the GISTEMP temperature change to the average temperature observed in Modena in the 1951–1980 base period (https://data.giss.nasa.gov/gistemp/).The sixth column contains the global CO2 concentration C in parts per million estimated from ice cores, from 1881 to 1958 (https://cdiac.ess-dive.lbl.gov/trends/co2/lawdome-data.html), and observed in the Mauna Loa Observatory (latitude 19.5362°N, longitude 155.5763°W, elevation 3397.00 m asl), Hawaii, from 1959 to 2019 (https://gml.noaa.gov/ccgg/trends/data.html).

title: Planktonic foraminifera shell counts and weights from Labrador Sea in the upper part of sediment cores HU2008-029-004TWC, HU91-045-93BX and MD99-2227

description: Counts of planktonic foraminifera shells in the upper samples of three sediment cores from the Labrador Sea: HU2008-029-004TWC, HU91-045-93BX and MD99-2227. Foraminifera shells were counted in a varying split of each sample, as indicated. Moreover, average species-specific weights were determined in some of the sample, as well as average shell weights of all species in each sample. Shell weight measurements were conducted with a Sartorius XM1000P micro balance (nominal resolution of 1 µg). The indicated ages of the depth intervals are mostly from published data. The two d14C dates of sediment core HU91-045-93BX were measured with the Mini Carbon Dating System (MICADAS) at the Alfred-Wegener-Institute Helmholtz Center for Polar and Marine Research. Shell counts and weight measurements were conducted to calculate the (mass) accumulation rates of planktonic foraminifera in the recent sediment samples.

description: Individual measurements of shell size and shell weight of distinct species of planktonic foraminifera from the sediment cores HU2008-029-004TWC, HU91-045-93BX and MD99-2227 from the Labrador Sea. Different shell size parameter (area, perimeter, minimum and maximum diameter, diagonal width and circle equivalent diameter) were measured using a KEYENCE VHX-6000 digital microscope. Individual shell weights were measured using a Sartorius Cubis®II ultra-micro lab balance (nominal resolution of 0.1 µg). Before weighing, the shells were left in the room for at least 24 hours to acclimate with the room, and for the water that was used to place them in the weighing boats to evaporate. The measurements were conducted to analyse the relationship of foraminifera shell size and weight, and to compare individual species-specific shell weight with bulk weighs conducted on samples from the same sediment core.
description: The analysed material was made available by the Université du Québéc à Montréal (UQAM) in the GEOTOP research center, which is supported by the Fonds de recherche du Québec – Nature et Technologies (FRQNT).
