title: Wapok Key Landscape for Conservation Land Cover and Validation Datasets (2000-2017)

description: The Wapok land cover and change dataset covers an area of 57 776km^2^ and mapped with dichotomous (8 land cover classes) and modular (up to 32 land cover classes) levels based on FAO's Land Cover Classification System (LCCS). High-resolution optical satellite imagery were used to generate dense time-series data from which the thematic land cover and change maps were derived (LC: 2017, LCC: 2000). The maps were fully verified and validated by an independent team to achieve the Copernicus Global Land Monitoring Programme's strict data quality requirements. An independent validation dataset was also collected and it is shared here. The validation dataset contains 3522 verified land cover points based on the [up to] 32 modular level land cover classes. Furthermore, two predefined symbology (QGIS legend files) for the land cover and validation datasets based on FAO's LCCS is also shared here to ease the visualization of them (Dichotomous and Modular levels). Further details regarding the sites selection, mapping and validation procedures are described in the corresponding publication: Szantoi, Zoltan; Brink, Andreas; Lupi, Andrea (2021): An update and beyond: key landscapes for conservation land cover and change monitoring, thematic and validation datasets for the African, Caribbean and Pacific region (in review, [Earth System Science Data|https://www.earth-system-science-data.net/]).

title: Peak metamorphic temperatures acquired through Raman Spectroscopy on Carbonaceous Material (RSCM) from the Northern Range, Trinidad

description: The Northern Range of Trinidad is a mountain range located along the northern Trinidadian coast formed through the oblique collision between the Caribbean and South American plates in the Oligocene and Miocene. Previous geothermometric attempts at characterizing the peak metamorphic temperatures across the Northern Range yielded results with large associated errors due to the low metamorphic grade and a lack of suitable index minerals. In order to better constrain the peak metamorphic temperatures across the Northern Range, as well as to investigate the presence and continuity of a previously described thermal gradient, we employ Raman spectroscopy on carbonaceous materials (RSCM), utilizing multiple calibrations to cover the range of peak temperatures in the area. Data were collected in 2019 using Raman spectrometers at the University of Torino (UNITO) in Italy and the Royal Ontario Museum (ROM) in Canada on 26 samples made from a variety of lithologies from across the Northern Range. Spectra were acquired from standard petrographic thin sections using a 532 nm laser at low power to avoid within-sample heating, with the analyzed carbonaceous material (CM) being hosted beneath transparent minerals to avoid the effects of sample preparation on the CM crystal structure. 3-4 accumulations of 15 seconds were collected for each CM grain in the range of 700-2000 cm^-1, with at least 15 spectra being collected for each of the 26 samples. Raman spectra were fit using the PeakFit software in accordance with the calibrations used (Beyssac et al., 2003; Aoya et al., 2010; Lahfid et al., 2010; Kouketsu et al., 2014 ); temperatures were then calculated using the relevant band parameters and are reported in this dataset along with the relevant calibration. This dataset provides information on the location, wellness of fit, spectrometer used, fitted band parameters, RSCM calibration, and calculated RSCM temperature for each sample analyzed from the Northern Range.

title: Three component shallow seismic mini-vibrator data of polar firn of Kohnen Station, East Antarctica

description: In 2012 we performed an active seismic experiment at Kohnen Station, (S 75.0041, E 0.0637), Antarctica. We recorded two perpendicular seismic profiles. The source was a minivibrator (ELVIS, wheelbarrow sized) producing a 30-240 Hz, 10 s linear sweep. The receivers were 24 3-component spiked geophones place at 10 m (parallel line 20120553) or 5 m separation (perpendicular line 20120554). The first arrivals from the diving wave of the correlated sweep records were used to derive elastic modeli from the firn. We present the raw uncorrelated sweeps, the correlated sweeps and stacks used in the publication Schlegel, R. et al. (2019).

title: Rock and palaeomagnetic evidence for the Plio-Pleistocene palaeoclimatic change recorded in Upper Rhine Graben sediments (Core Ludwigshafen-Parkinsel)

description: In the area of Ludwigshafen (Germany; Upper Rhine Graben (URG); Fig. 1) we sampled a core (P34) which was recovered during the exploration for groundwater resources. The core comprises 300 m of Quaternary and Tertiary sediments (Fig. 2). Rockmagnetic parameters measured are: NRM (natural remanent magnetization); characteristic remanent magnetization (ChRM, could be isolated using demagnetization experiments (alternating field and thermal) Fig. 3); magnetic susceptibility measured on core and discrete samples compared with interpretation of polarity (Fig. 5); as demonstrated in figure 6, a clear correlation of heavy mineral data (Hagedorn & Boenigk, 2008; doi:10.1016/j.quascirev.2005.01.018) and susceptibility data is apparent; the so-called S-ratio (Fig. 7a) gives us information about the relative amounts of high-coercivity ('hard') to low-coercivity ('soft') remanence and therefore a fair estimate of the importance of antiferromagnetics (goethite, hematite) versus ferrimagnetics (soft magnetite, iron-sulphides); "saturation"IRM curves (Fig. 7b, c) also show a clear subdivision in soft (above 177 m) and hard (below 177 m) remanence carriers; thermal demagnetization of "S"IRM identifies greigite or (Ti) -magnetite (Fig. 8a) for the upper (alpine influenced) part of the drill whereas the lower Pliocene part is dominated by greigite (Fig. 8b); alternating field (AF) demagnetization of samples from the upper part often show acquisition of significant gyroremanent magnetization (Fig. 10a), a typical property of greigite (Snowball, 1997; doi:10.1111/j.1365-246X.1997.tb04498.x); we used a technique after Van Velzen and Zijderfeld (1992; doi:10.1111/j.1365-246X.1992.tb00715.x) detecting greigite instead of pyrrhotite (Fig. 10b); Combination of different parameters in biplots can help to separate various magnetic components (Fig. 11 a+b). We applied this method by combining anhysteretic remanent magnetization (ARM) and IRM measurements in different ways. ARM against IRM (Fig. 11a) demonstrates high concentration differences for samples from the upper part (above 177 m) of the profile and narrow plotting (low concentration variations) for samples of the lower part (below 177 m); A similar plot, the relation of ARM normalized by IRM and ARM, emphasizes this result (Fig. 11b). Again, two different clusters (high coercivity mineral (goethite) in the lower and low coercivity mineral (greigite) in the upper part of the profile) are obvious (with the exception of some samples in a mixed zone).

title: Autonomous phase-sensitive radar (ApRES) measurements at a basal melt channel of the southern Filchner Ice Shelf, Antarctica between 2016/17 and 2017/18

description: The dataset consists of raw data from six autonomous phase-sensitive radar (ApRES) measurements. The ApRES with two bow-tie antennas were operated at a basal melt channel of the southern Filchner Ice Shelf, Antarctica near the Support Force Glacier. Five short-period ApRES were located at a cross-section of the channel, located east outside the channel (ApRES_oe), at the eastern steepest flank of the surface depression (ApRES_se), within the channel at the lowest surface depression (ApRES_low), at the western steepest flank (ApRES_sw) and west outside the channel (ApRES_we). All four ApRES operated for 9 to 13 days with a measuring interval of 15 minutes. The long-period ApRES (ApRES_oe_long) operated east outside the channel for 361 days with a measuring interval of 2 hours. The short-period ApRES were operated parallel to GPS stations (see doi:10.1594/PANGAEA.932441). These Lagrangian measurements allow the estimation of basal melt rates based on estimated vertical displacements of englacial and basal reflections. The ApRES is an autonomous operating frequency-modulated continuous wave (FMCW) radar that transmits a tone sweep – called chirp – ranging from 200 to 400 MHz over a period of one second. In order to improve the signal-to-noise ratio, 100 chirps were transmitted within a single measurement. These measurements were repeated every 24 hours. Background of the ApRES-system is published by Brennan et al. (2014) and Nicholls et al. (2015). The processing of the data is described in Stewart (2018), Stewart et al. (2019) and Vankova et al. (2020).

title: King penguin ornamentation and acoustics

description: King penguins are sexually monomorphically ornamented seabirds that perform a complex visual and acoustic courtship display. Coloured beak spots and ear patches contain information about the condition and physiological status of adult males and females, but their role as a signal of age has previously only been studied in young birds. Vocalizations have mainly been studied as signals of individuality and not in the context of courtship. We investigate two multicomponent signals in the context of mate choice by analysing beak spot, ear patch, and call parameters of wild king penguins. We explore the relation between those signals and age as well as age-classes (chicks, juveniles, adults). Ornament parameters were weakly correlated to continuous age in males, but not in females, while acoustic parameters were highly correlated to continuous age in both sexes. The calls' fundamental frequency and energy parameters, and all the beak spot parameters reliably classified individuals into their age-class. Since age-class was redundantly encoded in both acoustic and colour parameters, we hypothesize that calls and ornaments function as back-up signals that increase the chance of accurately conveying the age-class of the sender to receivers. King penguins might sequentially analyse age-class signals during courtship, where acoustic signals serve as long-range communication when sender and receiver are out of sight, and ornamentation signals become important at close range. We show the importance of considering bimodal, multicomponent signals when studying complex behaviour and discuss how signalling environment, the species' life-history and mating system influence the evolution of communication signals.
