description: New, accurately located and well‐preserved agnostid trilobite material has been collected from the type locality of the Drumian (middle Cambrian, Miaolingian) Manuels River Formation, Newfoundland, Canada. The well‐exposed grey to black shales containing the fauna were deposited on the former microcontinent Avalonia. Four interval zones for the succession are proposed, namely, the Tomagnostus fissus, Hypagnostus parvifrons, Ptychagnostus atavus and Ptychagnostus punctuosus zones. The Tomagnostus fissus and Ptychagnostus atavus zones are distinct from each other, which leads to a significantly shorter and stratigraphically higher Ptychagnostus atavus Zone compared with other sections (Scandinavia, South China, Utah and Nevada, Greenland). Specimens of Ptychagnostus atavus, however, occur abundantly, with 107 specimens identified in a short interval of the succession. The Ptychagnostus punctuosus Zone can be correlated globally. The faunal assemblage is comparable to that of Scandinavia, Greenland and England. Ptychagnostus affinis is recorded for the first time from Avalonia. The 1408 collected specimens were assigned to the suborders Agnostina and Eodiscina and to the families Peronopsidae and Ptychagnostidae, and Condylopygidae and Eodiscidae, respectively, with the following species: Peronopsis fallax (Linnarsson), Peronopsis scutalis (Hicks), Hypagnostus parvifrons (Linnarsson), Ptychagnostus punctuosus (Angelin), Ptychagnostus affinis (Brøgger), Ptychagnostus atavus (Tullberg), Tomagnostus fissus (Lundgren), Tomagnostus perrugatus (Grönwall), Pleuroctenium granulatum (Barrande) and Eodiscus punctatus (Salter).

description: Accounting for ecosystem service values in wildfire risk mitigation remains a challenge. In this study we utilize public participatory GIS methods to measure ecosystem service values and overlay those values with maps of wildfire hazard. Our first objective is to understand sociocultural demand for ecosystem services, and our second objective is to show how non-monetary ecosystem service valuation methods can be used to inform wildfire risk mitigation decisions. Regulating ecosystem services, such as water quality, biodiversity/habitat, and air quality, along with recreation and aesthetics, were the most highly valued ecosystem services in our study. These ecosystem service values were clustered around roads, towns, and water features and correlated with accessibility, education, and income. These values also had significant overlap with wildfire hazard, suggesting that this non-monetary mapping approach could provide a more participatory method of incorporating people’s preferences into decisions about where to target wildfire mitigation efforts.

description: A personal norms intervention strategy is an effective way to reduce food waste behavior. However, the mechanism controlling how personal norms affect food waste behavior needs to be further investigated. In addition, previous studies have reported that weight control is part of this mechanism, but few studies have focused on how internal (personal norms) and external beauty (weight control) act simultaneously on individuals. This study constructed an analytical framework with personal norms as the independent variable, emotions as the mediating variable, and weight control as the moderating variable from a cognitive perspective. A stratified regression approach was used to analyze 835 validated questionnaires on food waste at the consumption level (outside the home) that were collected from across China. The results showed that (1) Chinese consumer personal norms about eating at restaurants and outside the home exacerbated food waste behavior; (2) consumer emotions mediated the effect of personal norms on food waste behavior; and (3) weight control moderated both paths associated with the mediating effect of emotions, and its cubic term had a more significant moderating effect. Policy recommendations are proposed based on the conclusions of this study that will effectively reduce food waste behavior.

description: Zusammenfassung Alexander von Humboldt betätigte sich in unterschiedlichsten Wissensbereichen und vielen Disziplinen. Obwohl er natürlich kein Jurist war, hat er sich vielfach mit Problemen befasst, die zu seinen Lebzeiten und danach zu grundlegenden Fragen des in der Entstehung begriffenen Völkerrechts avancierten. So beschäftigte er sich mit dem Verbot der Sklaverei und der Abschaffung der Rassendiskriminierung, mit der Fixierung von territorialen Grenzen von Staaten, mit Seegrenzen, der Förderung des Welthandels und der Hoheitsgewalt im Luft- und im Weltraum. Viele dieser Fragen wurden später in internationalen Verträgen kodifiziert, weshalb man Humboldt als Vordenker des Völkerrechts bezeichnen kann. Diese von der internationalen Humboldt-Forschung bislang nicht als Forschungsfeld erkannte Dimension seines Wirkens wird nachfolgend erstmals vertiefend beleuchtet. Abstract Alexander von Humboldt was active in the most diverse fields of knowledge and many disciplines. Although of course he was not a lawyer, he has often dealt with problems that became fundamental questions of emerging international law during his lifetime and afterwards. His work dealt with the prohibition of slavery and the abolition of racial discrimination, the fixing of territorial borders of states, maritime borders, the promotion of world trade and sovereignty in air and space. Many of these questions were later incorporated into international treaties, which is why Humboldt can be called a mastermind of international law. This dimension of his work, which has not yet been recognized as a research field by international Humboldt research, will be examined in greater depth for the first time in the following. Résumé Alexandre von Humboldt a été actif dans les domaines de connaissance les plus divers et dans de nombreuses disciplines. Bien qu’il ne soit pas juriste, il a souvent traité des problématiques qui sont devenues à bien des égards, de son vivant et par la suite, des questions fondamentales du droit international émergent. Il traita ainsi des sujets comme l’interdiction de l’esclavage et l’abolition de la discrimination raciale, la démarcation des frontières territoriales des États, des frontières maritimes, la promotion du commerce mondial et la souveraineté dans l’air et l’espace. Beaucoup de ces questions ont ensuite été codifiées dans des traités internationaux, de sorte que l’on peut qualifier Humboldt de précurseur du droit international. Cette dimension de son action, qui n’a pas encore été reconnue comme un domaine de recherche par la recherche internationale au sujet de Humboldt, sera examinée ci-après pour la première fois de manière plus approfondie.

description: The changes of defect characteristics induced by accelerated lifetime tests on the heterostructure n-ZnO/i-ZnO/CdS/Cu(In, Ga)(S, Se)$_2$/Mo relevant for photovoltaic energy conversion are investigated. We subject heterojunction and Schottky devices to extended damp heat exposure at 85$^{\circ}$C ambient temperature and 85% relative humidity for various time periods. In order to understand the origin of the pronounced changes of the devices, we apply current--voltage and capacitance--voltage measurements, admittance spectroscopy, and deep-level transient spectroscopy. The fill factor and open-circuit voltage of test devices are reduced after prolonged damp heat treatment, leading to a reduced energy conversion efficiency. We observe the presence of defect states in the vicinity of the CdS/chalcopyrite interface. Their activation energy increases due to damp heat exposure, indicating a reduced band bending at the Cu(In, Ga)(S, Se)$_2$ surface. The Fermi-level pinning at the buffer/chalcopyrite interface, maintaining a high band bending in as-grown cells, is lifted due to the damp-heat exposure. We also observe changes in the bulk defect spectra due to the damp-heat treatment.

Contributions of dark matter annihilation to the global 21cm spectrum observed by the EDGES experiment

description: The EDGES experiment has observed an absorption feature in the global 21 cm spectrum with a surprisingly large amplitude. These results can be explained by decreasing the kinetic temperature of baryons, which could be achieved through the scattering between the baryons and cold dark matter particles. It seems that the most researched dark matter annihilation model is not able to explain such a large amplitude, since the interactions between the particles produced by the dark matter annihilation and the particles that have been present in the Universe could increase the baryonic temperature. Recently, C. Feng and G. Holder have suggested that the large amplitude in the global 21 cm spectrum could be produced by considering the possible excess of the early radio radiation. In this paper, we propose that the dark matter annihilation still works to explain the large amplitude observed by the EDGES experiment. Even including the dark matter annihilation, the large absorption amplitude in the global 21 cm spectrum can be produced by considering the possible excess of the early radio radiation.

description: We investigate the spatial distribution of magnetic polarities in the penumbra of a spot observed very close to disk center. High-spatial resolution, high-cadence magnetograms taken with the Narrowband Filter Imager aboard Hinode are used in this study. They provide continuous and stable measurements in the photospheric Fe I 630.25 line for long periods of time. We discover small-scale, elongated, bipolar magnetic structures that appear in the mid penumbra and move radially outward across the penumbra. They occur in between the more vertical fields of the penumbra, and can be associated with the horizontal fields that harbor the Evershed flow. Many of them cross the outer penumbral boundary, becoming moving magnetic features in the sunspot moat. We determine the properties of these structures, including their sizes, proper motions, footpoint separation, and lifetimes. The bipolar patches can be interpreted as being produced by sea-serpent field lines that originate in the mid-penumbra and eventually leave the spot in the form moving magnetic features. The existence of such field lines has been inferred from Stokes inversions of spectropolarimetric measurements at lower angular resolution, but this is the first time they are imaged directly. Our observations add another piece of evidence in favor of the uncombed structure of penumbral magnetic fields.

description: We have studied the iso-height lines on the $\mathrm{WO_3}$ surface as a physical candidate for conformally invariant curves. We have shown that these lines are conformally invariant with the same statistics of domain walls in the critical Ising model. They belong to the family of conformal invariant curves called Schramm-Loewner evolution (or $SLE_κ$), with diffusivity of $κ\sim 3$. This can be regarded as the first experimental observation of SLE curves. We have also argued that Ballistic Deposition (BD) can serve as a growth model giving rise to contours with similar statistics at large scales.

Geodynamic Modeling of Lithospheric Removal and Surface Deformation: Application to Intraplate Uplift in Central Mongolia

description: Intraplate surface deformation is enigmatic and the underlying mechanisms responsible are not fully understood. We use thermo‐mechanical numerical modeling to explore the conditions under which lithospheric removal processes can occur and investigate the timing and amplitude of consequent surface deformation. We allow lithospheric removal to develop dynamically and self‐consistently by applying a phase transition and density jump that is hypothesized to be a consequence of metamorphic eclogitization in a thickened crust, rather than simply imposing an initial dense block. By systematically varying parameters, we test their influence and control on lithospheric removal. We confirm that a weak and dense lower crust, a hot crust‐mantle boundary, and a convergent regime are critical requirements for delamination‐style removal. We apply these results to central Mongolia, which is an ideal natural laboratory for studying intraplate surface uplift because of its high topography and location in the continental interior. We determine that the physical parameters and structure inferred in this region match the conditions for delamination. Thus, model outputs are evaluated against the available observational evidence. We find that the removal of the lithosphere by delamination can explain: the dome‐shaped topographic pattern and elevated surface; the thin lithosphere and its structure; the elevated temperature at the crust‐mantle boundary. Additionally, it is hypothesized that delamination leads to magmatism due to mantle decompression melting, consistent with intraplate volcanism. Ultimately, the results suggest that lithospheric removal by delamination is a physically plausible mechanism and a potential explanation for intraplate uplift.

description: A mild correlation exists in active galaxies between the mean black hole accretion, as traced by the mean X-ray luminosity $\left$, and the host galaxy stellar mass M$_*$, characterised by a normalisation steadily decreasing with cosmic time and lower in more quiescent galaxies. We create comprehensive semi-empirical mock catalogues of active black holes to pin down which parameters control the shape and evolution of the $\left-{\rm M}_*$ relation of X-ray detected active galaxies. We find that the normalisation of the $\left-{\rm M}_*$ relation is largely independent of the fraction of active galaxies (the duty cycle), but strongly dependent on the mean Eddington ratio, when adopting a constant underlying M$_{\rm BH}-{\rm M}_*$ relation as suggested by observational studies. The data point to a decreasing mean Eddington ratio with cosmic time and with galaxy stellar mass at fixed redshift. Our data can be reproduced by black holes and galaxies evolving on similar M$_{\rm BH}-{\rm M}_*$ relations but progressively decreasing their average Eddington ratios, mean X-ray luminosities, and specific star formation rates, when moving from the starburst to the quiescent phase. Models consistent with the observed $\left-{\rm M}_*$ relation and independent measurements of the mean Eddington ratios, are characterised by M$_{\rm BH}-{\rm M}_*$ relations lower than those derived from dynamically measured local black holes. Our results point to the $\left-{\rm M}_*$ relation as a powerful diagnostic to: 1) probe black hole-galaxy scaling relations and the level of accretion onto black holes; 2) efficiently break the degeneracies between duty cycles and accretion rates in cosmological models of black holes.

description: In this paper we discuss Bose-Einstein spinor condensates for F=1 atoms in the context of 87Rb, as studied experimentally by the Stamper-Kurn group [Sadler et al. Nature (2006)]. The dynamical quantum fluctuations of a sample that starts as a condensate of N atoms in a pure F=1, m_F = 0 state are described in analogy to the `two-mode squeezing' of quantum optics in terms of an su(1,1) algebra. In this system the initial m_F=0 condensate acts as a source (`pump') for the creation pairs of m_F =+1,-1 atoms. We show that even though the system as a whole is described by a pure state with zero entropy, the reduced density matrix for the m_F = +1 degree of freedom, obtained by tracing out the m_F = -1,0 degrees of freedom, corresponds to a thermal state. Furthermore, these quantum fluctuations of the initial dynamics of the system provide the seeds for the formation of domains of ferromagnetically aligned spins.

description: Ecohydrological processes in tropical rainforests are insufficiently understood, and existing studies yield contradictory results. We investigated relative contributions of different soil depths to tree water uptake of 83 trees and possible species‐specific differences in a 50 × 50 m forest plot at four dates in a tropical montane forest in Kenya using stable water isotopes and the Bayesian mixing model framework MixSIAR. We found distinct individual tree differences (e.g. Drypetes gerrardii taking 75% of its water from <0.5 m, or a rather large shift in uptake patterns based on the climatic conditions, that is the fourth sampling date), but no consistent species‐specific or small‐scale spatiotemporal patterns in water uptake and depth contributions. Soil water δ18O showed a lateral variation of up to 6‰, which was accounted for by a spatial interpolation of soil water isotopes and enabled us to improve allocations of water uptake sources to individual trees. Our results show that ignoring the lateral variability of water isotope signatures in soils complicates the applicability of a mixing model in this context and might be a widespread constraint reducing the validity and comparability of mixing model results. Further research on underlying processes of water fluxes in forest ecosystems is urgently needed and we point out the need for considering large individual differences in water uptake patterns and small‐scale variability of soil water isotopic composition despite homogeneous soil characteristics.

description: Future observations of the large-scale structure have the potential to investigate cosmological models with a high degree of complexity, including the properties of gravity on large scales, the presence of a complicated dark energy component, and the addition of neutrinos changing structures on small scales. Here we study Horndeski theories of gravity, the most general minimally coupled scalar-tensor theories of second order. While the cosmological background evolution can be described by an effective equation of state, the perturbations are characterised by four free functions of time. We consider a specific parametrisation of these functions tracing the dark energy component. The likelihood of the full parameter set resulting from combining cosmic microwave background primary anisotropies including their gravitational lensing signal, tomographic angular galaxy clustering and weak cosmic shear, together with all possible non-vanishing cross-correlations is evaluated; both with the Fisher-formalism as well as without the assumption of a specific functional form of the posterior through Monte-Carlo Markov-chains (MCMCs). Our results show that even complex cosmological models can be constrained and could exclude variations of the effective Newtonian gravitational coupling larger than 10\% over the age of the Universe. In particular, we confirm strong correlations between parameter groups. Furthermore, we find that the expected contours from MCMC are significantly larger than those from the Fisher analysis even with the vast amount of signal provided by stage IV experiments, illustrating the importance of a proper treatment of non-Gaussian likelihoods and the high level of precision needed for unlocking the sensitivity on gravitational parameters.

description: Zusammenfassung Losgelöst vom eurozentrischen Systemdenken sowie den Vorurteilen der Philosophie und Wissenschaften bediente sich Alexander von Humboldt eines transnationalen Wissensreservoirs, das er in seinen Werken zu einem länder- und sprachübergreifenden Wissensnetzwerk verband. Die vorliegende quantitative Auswertung der intertextuellen Bezüge des Essai politique sur le royaume de la Nouvelle-Espagne zeigt zum einen deren Vielzahl und Komplexität auf, zum anderen, inwieweit Humboldt sich zwischen zwei sich diskursiv abgrenzenden Welten bewegt und sich unabhängig von der Abstammung oder Herkunft der Autoren mit deren Forschungsergebnissen auseinandersetzt. Der relativ große Anteil an amerikanischen Werken, auf die Humboldt in seinem Essai Bezug nimmt, verdeutlicht im Besonderen den hohen Stellenwert, den sie für seine eigenen Forschungen einnahmen und im Allgemeinen den Beginn der wachsenden Bedeutung der Wissenschaft in Amerika. Abstract Detached from Eurocentric systems thinking and the prejudices of philosophy and science, Alexander von Humboldt used a transnational knowledge reservoir, which he summarized in his work to form a cross-country and cross-language knowledge network. This quantitative evaluation of the intertextual references of the Essai politique sur le royaume de la Nouvelle-Espagne shows on the one hand their variety and complexity, on the other hand to what extent Humboldt moves between two discursively different worlds and deals with the research results of authors, regardless of their origin or lineage. The relatively high percentage of American works to which Humboldt refers in his essay reflects in particular their great importance for his own research work and, in general, the beginning of the increasing significance of science in America. Resumen Independientemente del pensamiento sistémico eurocéntrico y los prejuicios de la filosofía y las ciencias, Alexander von Humboldt hizo uso de una reserva de conocimiento transnacional, que combinó en sus trabajos para formar una red de ciencia que abarcó países e idiomas. La presente evaluación cuantitativa de las referencias intertextuales del Essai politique sur le royaume de la Nouvelle-Espagne muestra, por un lado, su variedad y complejidad, por otro, hasta qué punto Humboldt se mueve entre dos mundos discursivamente diferentes y cómo trata los resultados de investigación, independientemente del origen o perfil de los autores. La proporción relativamente grande de obras americanas a las que Humboldt se refiere en su Ensayo ilustra, en particular, la gran importancia que le dieron a su propia investigación y, en general, el comienzo del creciente valor de la ciencia en América.

Influence of Thermodynamic State Changes on Surface Cloud Radiative Forcing in the Arctic: A Comparison of Two Approaches Using Data From AFLUX and SHEBA
Creators: name: Stapf, Johannes

Publisher: name: FID GEO

description: The cloud radiative forcing (CRF) quantifies the warming or cooling effects of clouds. To derive the CRF, reference values of net (downward minus upward) irradiances in cloud‐free conditions are required. There are two groups of techniques to estimate these reference values; one is based on radiative transfer modeling, and a second group uses measurements in cloud‐free situations. To compare both approaches, we first look at a case study from the airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer (AFLUX) campaign, where a moving cloud field with a sharp edge separating a cloudy boundary layer from an adjacent evolving cloud‐free area was probed. These data enabled the quantification of the impact of changing atmospheric and surface properties relevant for the reference net irradiances in cloud‐free conditions. The systematically higher surface albedo below clouds compared to cloud‐free conditions, results in a 11 W·m−2 smaller shortwave cooling effect by clouds estimated from the radiative transfer approach compared to the measurement‐based one. Due to the transition of thermodynamic parameters between the cloudy and cloud‐free atmospheric states, a 20 W·m−2 stronger warming effect is estimated by the radiative transfer approach. In a second step, radiative transfer simulations based on radiosoundings from the Surface Heat Budget of the Arctic Ocean campaign are used to quantify the impact of the vertical profiles of thermodynamic properties on the CRF. The largest difference between the longwave CRF estimated by the two methods is found in autumn with up to 25 W·m−2.
description: Key Points: Different approaches to derive the surface cloud radiative forcing (CRF) are compared using data of a case study of the AFLUX campaign. Radiative transfer‐based approaches provide a systematically stronger warming effect of clouds than observed. For Surface Heat Budget of the Arctic Ocean, atmospheric thermodynamic state changes and profile properties are identified as decisive for the respective annual cycle of longwave CRF.

General Circulation Model Selection Technique for Downscaling: Exemplary Application to East Africa

Year: 2021

description: Downscaling is widely used in studies of local and/or regional climate as it yields a greater spatial resolution than general circulation models (GCMs) can provide. It utilizes GCM output or reanalysis data, which is transformed using mathematical relationships or used to force the lateral boundaries of a regional climate model. However, there is no set selection technique to determine which GCM realization(s) to employ. Here, a comprehensive yet easily applicable model selection technique for studies requiring GCM data as a constraint was developed. The technique evaluates, with respect to a reanalysis product and/or observational data, the ability of GCM realizations to reconstruct the mean state of the climate and the space‐time climatic anomalies for the atmospheric state variables at three distinct pressure levels. It was applied to the region of East Africa, where GISS‐E2‐H r6i1p3 was found to perform the strongest. The top ranked realizations were found to better capture processes when evaluated for the example of the Indian Ocean Dipole. Furthermore, the surface air temperature and precipitation from three 10‐year regional climate model simulations, one forced by the Modern‐Era Retrospective Analysis for Research and Applications version 2 reanalysis, one forced by the top ranked GCM, and one by the lowest ranked one, were compared to gridded observations. Results show that using a top ranked GCM for the boundary conditions leads to a better dynamical downscaling simulation than a low‐ranked GCM, suggesting the potential of the proposed technique for future downscaling techniques.

description: We believe that a wide range of physical processes conspire to shape the observed galaxy population but we remain unsure of their detailed interactions. The semi-analytic model (SAM) of galaxy formation uses multi-dimensional parameterizations of the physical processes of galaxy formation and provides a tool to constrain these underlying physical interactions. Because of the high dimensionality, the parametric problem of galaxy formation may be profitably tackled with a Bayesian-inference based approach, which allows one to constrain theory with data in a statistically rigorous way. In this paper, we develop a generalized SAM using the framework of Bayesian inference. We show that, with a parallel implementation of an advanced Markov-Chain Monte-Carlo algorithm, it is now possible to rigorously sample the posterior distribution of the high-dimensional parameter space of typical SAMs. As an example, we characterize galaxy formation in the current $\Lambda$CDM cosmology using stellar mass function of galaxies as observational constraints. We find that the posterior probability distribution is both topologically complex and degenerate in some important model parameters. It is common practice to reduce the SAM dimensionality by fixing various parameters. However, this can lead to biased inferences and to incorrect interpretations of data owing to this parameter covariance. This suggests that some conclusions obtained from early SAMs may not be reliable. Using synthetic data to mimic systematic errors in the stellar mass function, we demonstrate that an accurate observational error model is essential to meaningful inference.

description: The structure of spacetime, quantum field theory, and thermodynamics are all connected through the concepts of the Hawking and Unruh temperatures. The possible detection of the related radiation constitutes a fundamental test of such subtle connections. Here a scheme is presented for the detection of Unruh radiation based on currently available laser systems. By separating the classical radiation from the Unruh-response in frequency space, it is found that the detection of Unruh radiation is possible in terms of soft x-ray photons using current laser-electron beam technology. The experimental constraints are discussed and a proposal for an experimental design is given.

description: We present stellar evolution calculations for Population III stars for both single and binary star evolution. Our models include 10 Msun and 16.5 Msun single stars and a 10 Msun model star that undergoes an episode of accretion resulting in a final mass of 16.1 Msun. For comparison, we present the evolution of a solar heavy element abundance model. We use the structure from late stage evolution models to calculate simulated supernova light curves. Light curve comparisons are made between accretion and non-accretion progenitor models, and models for single star evolution of comparable masses. Where possible, we make comparisons to previous works. Similar investigations have been carried out, but primarily for solar or near solar heavy metal abundance stars and not including both the evolution and supernovae explosions in one work.

description: Abstract Though Humboldt’s travels to the Americas have been analyzed from a wide range of viewpoints, there are specific aspects that still await further investigation. Little is written about Humboldt in the field, specifically how he moved between different locations and simultaneously measured and mapped places and phenomena. The aim of this article is to discuss the triad movement-measure-ment-map that led to the development of specific practices of knowledge building on the move. Humboldt’s search for the connections between the watersheds of the Orinoco and the Amazon rivers and the resulting maps and drawings are used as an example to point out his cartographic impulse in his quest to understand and explain the physical world. Zusammenfassung Obwohl Humboldts Reisen nach Amerika unter ver-schiedenen Gesichtspunkten analysiert wurden, gibt es bestimmte Aspekte, die noch weiter untersucht werden müssen. Wenig ist jedoch über Humboldt im Feld geschrieben, insbesondere darüber, wie er sich zwischen verschiedenen Orten bewegte und gleichzeitig Lokalitäten und Phänomene maß und kartierte. Das Ziel dieses Artikels ist es, die Triade Bewegung-Messung-Landkarte zu diskutieren, die zur Entwicklung spezifischer Praktiken des „Wissenschaffens“ in Bewegung führte. Humboldts Suche nach den Verbindungen zwischen den Wassereinzugsgebieten des Orinoco und des Amazo-nasflusses sowie die daraus resultierenden Karten und Zeichnungen dienen als Beispiel, um seinen kartografischen Impuls bei seinem Bestreben, die physische Welt zu verstehen und zu erklären, hervorzuheben. Resumen Aunque los viajes de Humboldt a las Américas han sido analizados desde una amplia gama de puntos de vista, hay aspectos específicos que aún esperan una mayor investigación. Poco se escribe sobre Humboldt en el campo, específicamente cómo se movió entre diferentes lugares y simultáneamente midió y cartografió lugares y fenómenos. El objetivo de este artículo es discutir la tríada movimien-to-medición-mapa que condujo al desarrollo de prácticas específicas de construcción de conocimiento en movimiento. La investigación de Humboldt de las conexiones entre las cuencas hidrográficas del Orinoco y del Amazonas y los mapas y dibujos resultantes se utiliza como un ejemplo para señalar su impulso cartográfico en su búsqueda para comprender y explicar el mundo físico.
