description:
Geological mapping represents an important qualification within the framework of geoscientific programmes of study. The GeoMoDiM project, funded by Bonn University, aims to firmly integrate digitally supported geological mapping into the curriculum. In particular, the tablet- and cloud-based data collection in the field is to be prepared, carried out and evaluated with GIS support. This approach saves numerous work steps and avoids sources of error, allowing live communication and data exchange in the field.

This new procedure is already in practice, involving the students in the optimizing and streamlining process. Here we show that using tablets with QField the process of mapping can be improved through the ability of gathering all the data in one application compatible with the current workflow of QGIS, saving time and simplifying use. On top we integrate photogrammetry in the didactics, incorporating 3D models of outcrops into the subsequent analysis.

A second aim of this digital approach is to integrate students, who cannot participate in the fieldwork, into the process through video communication and live data exchange with partners in the field. Controlling of the fieldwork can be done online from a base station, evaluating, exchanging datasets and interpretative approaches with the participants in the field. Additionally, we focus on participants with disabilities, who are unable to join the field experience, they will benefit from this new didactic approach. The next step of this project is to open this new perspective to other research areas as botany and soil sciences.

description: We present our analysis of Kepler observations of 29 RR Lyrae stars, based on 138-d of observation. We report precise pulsation periods for all stars. Nine of these stars had incorrect or unknown periods in the literature. Fourteen of the stars exhibit both amplitude and phase Blazhko modulations, with Blazhko periods ranging from 27.7 to more than 200 days. For V445 Lyr, a longer secondary variation is also observed in addition to its 53.2-d Blazhko period. The unprecedented precision of the Kepler photometry has led to the discovery of the the smallest modulations detected so far. Moreover, additional frequencies beyond the well-known harmonics and Blazhko multiplets have been found. These frequencies are located around the half-integer multiples of the main pulsation frequency for at least three stars. In four stars, these frequencies are close to the first and/or second overtone modes. The amplitudes of these periodicities seem to vary over the Blazhko cycle. V350 Lyr, a non-Blazhko star in our sample, is the first example of a double mode RR Lyrae star that pulsates in its fundamental and second overtone modes.

Constrained dynamics with frictional contact on smooth surfaces
Creators: name: Larionov, Egor
Publisher: name: University of British Columbia
Year: 2023

description: Friction and contact pose a great challenge to efficient and accurate simulation of deformable objects for computer graphics and engineering applications. In contrast to many engineering applications, simulation software for graphics often permits larger approximation errors in favour of better predictability, controllability and efficiency. This dissertation explores modern methods for frictional contact resolution in computer graphics. In particular, the focus is on offline simulation of smooth elastic objects subject to contact with other elastic solids and cloth. We explore traditional non-smooth friction formulations as well as smoothed frictional contact, which lends itself well to differentiable simulation and analysis. We then explore a particular application of differentiable simulation to motivate the direction of research. In graphics, even smooth objects are typically approximated using piecewise linear polyhedra, which exhibit sliding artifacts that can be interpreted as artificial friction making simulations less predictable. We develop a technique for improving fidelity of sliding contact between smooth objects. Frictional contacts are traditionally resolved using non-smooth models, which are complex to analyse and difficult to compute to a desirable error estimate. We propose a unified description of the equations of motion subject to frictional contacts using a smooth model that converges to an accurate friction response. We further analyse the implications of this formulation and compare our results to state-of-the-art methods. The smooth model uniquely resolves frictional contacts, while also being fully differentiable. This allows inverse problems using our formulation to be solved by gradient-based methods. We begin our exploration of differentiable simulation applications with a parameter estimation task. Elastic parameters are estimated for a three distinct cloth materials using a novel capture, registration and estimation pipeline. Static equilibrium cloth configurations are efficiently estimated using a popular compliant constraint dynamics. In this work we address a common issue of bifurcation in cloth, which causes final configuration mismatches during estimation. Finally, we postulate an extension to compliant constraint dynamics using our friction model, to show how our previous work can be used in parameter estimation tasks involving contact and friction.

description:
Tridacna are important archives for (sub)tropical marine palaeoenvironmental conditions. Their longevity (up to 100 years), large aragonitic shells (up to 1m) and rapid shell accretion (mm-cm/year) make them ideal to give insights into region specific climate and environmental variability. Highly spatially-resolved analytical techniques such as LA-ICPMS mean that geochemical data can be retrieved at a high temporal resolution (subdaily). Tridacna, with their daily banding and growth rates of tens of µm/day, are ideal candidates for applying this methodology evaluating seasonality and extreme weather events in (sub-)tropical reefs since their appearance in the early Miocene. Studies of seasonal records and information on extreme weather events from past climate settings can help inform model assessment exercises regarding how seasonality might change in future climate scenarios. In this study we present a multiproxy record from a 250 mm large late Miocene Tridacna from East Borneo spanning several decades, with subseasonally resolved stable δ18O and δ13C data and sub-daily resolved elemental ratio data (B, Na, Mg, Sr, Ba to Ca). By applying Daydacna, a recently developed python script that enables daily cycle based internal age modelling, we can create an age model of the shell, which forms the basis for the temporal reassignment of the geochemical data. Displaying geochemical data against time rather than shell distance improves multi-annual as well as inter-organism comparisons for palaeoseasonality reconstructions. We reconstruct seasonal growth rate variability and compare it to the corresponding elemental and isotopic ratios to evaluate the relationships between geochemical signals, shell growth and environmental parameters.

description: We present a comprehensive study of the optical properties of InAs/InP self-assembled quantum dots (QDs) using an empirical pseudopotential method and configuration interaction treatment of the many-particle effects. The results are compared to those of InAs/GaAs QDs. The main results are: (i) The alignment of emission lines of neutral exciton, charged exciton and biexciton in InAs/InP QDs is quite different from that in InAs/GaAs QDs. (ii) The hidden correlation in InAs/InP QDs is 0.7 - 0.9 meV, smaller than that in InAs/GaAs QDs. (iii) The radiative lifetimes of neutral exciton, charged exciton and biexciton in InAs/InP QDs are about twice longer than those in InAs/GaAs QDs. (v) The phase diagrams of few electrons and holes in InAs/InP QDs differ greatly from those in InAs/GaAs QDs. The filling orders of electrons and holes are shown to obey the Hund's rule and Aufbau principle, and therefore the photoluminescence spectra of highly charged excitons are very different from those of InAs/GaAs QDs.

description: The essential branched-chain amino acids leucine, isoleucine and valine are considered anabolic and stimulate protein synthesis in the muscles as well in the liver. They also promote muscle recovery and contribute to glucose homeostasis. Recent studies in critically ill patients have demonstrated that depletion of plasma leucine is associated with increased mortality, but data in the non-critical care setting is lacking. This secondary analysis of the randomized controlled Effect of early nutritional support on Frailty, Functional Outcomes, and Recovery of malnourished medical inpatients Trial (EFFORT), investigated the impact of leucine, isoleucine, and valine metabolism on clinical outcomes. The primary endpoint was 180-day all-cause mortality. Among 238 polymorbid patients with available metabolite measurements, low serum leucin levels were associated with a doubled risk of 180-day all-cause mortality in a fully adjusted regression model (adjusted HR 2.20 [95% CI 1.46-3.30], p < 0.001). There was also an association with mortality for isoleucine (1.56 [95% CI 1.03-2.35], p = 0.035) and valine (1.69 [95% CI 1.13-2.53], p = 0.011). When comparing effects of nutritional support on mortality in patients with high and low levels of leucine, there was no evidence of significant differences in effectiveness of the intervention. The same was true for isoleucine and valine. Our data suggest that depletion of leucine, isoleucine, and valine among malnourished polymorbid patients is associated with increases in long-term mortality. However, patients with low metabolite levels did not show a pronounced benefit from nutritional support. Further research should focus on the clinical effects of nutritional support in patients with depleted stores of essential branched-chain amino acids. clinicaltrials.gov as NCT02517476 (registered 7 August 2015).

description: Thermoelectric properties of the chemically-doped intermetallic narrow-band semiconductor FeGa3 are reported. The parent compound shows semiconductor-like behavior with a small band gap (Eg = 0.2 eV), a carrier density of ~ 10(18) cm-3 and, a large n-type Seebeck coefficient (S ~ -400 μV/K) at room temperature. Hall effect measurements indicate that chemical doping significantly increases the carrier density, resulting in a metallic state, while the Seebeck coefficient still remains fairly large (~ -150 μV/K). The largest power factor (S2/ρ = 62 μW/m K2) and corresponding figure of merit (ZT = 0.013) at 390 K were observed for Fe0.99Co0.01(Ga0.997Ge0.003)3.

description:
Tridacna shells feature macroscopically visible bands (at mm scale) as well as microscopically visible daily banding (at µm scale). To evaluate the lifespan of an individual, the presumably seasonal macroscopically visible bands can be counted, or stable oxygen isotope analysis can be used to identify seasonal cycles. However, these approaches may not always be conclusive, especially for Tridacna which at times display irregular seasonal growth patterns and often grow in equatorial areas with low seasonal SST variability and heavy seasonal precipitation, influencing δ18O seawater values. Counting the daily bands (manually or with software-based image analysis) gives a more accurate internal age model with high temporal resolution, but daily banding is not always visually retrievable in fossil specimens, hampering the production of a precise age estimate. We show that daily geochemical cycles can be measured with highly-spatially resolved laser-ablation inductively coupled plasma mass spectrometry (LA-ICPMS; 3 x 33 µm laser slit) in our Miocene (~10 Ma) specimen, even in areas where daily banding is not visible. We present a python script Daydacna, in which we use wavelet transformation on the measured daily geochemical cycles to quantify varying daily growth rates throughout the shell. This provides a robust alternative to visual band counting.  The resulting age model can be used to quantify seasonal growth rate variability over several decades and provide a basis for time resolved sub-seasonal paleoenvironmental proxy evaluation.

title: Subduction and collisional orogenesis: comparison of model predictions and observations with application to the Alpine orogeny and Tibetan plateau
Creators: name: Schmalholz, Stefan Markus
Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2023

description:
The Alps are one of the best studied orogens, but arguably also one of the most disputed ones. Several major geodynamic processes remain unclear, such as the mechanism of (U)HP rock exhumation, for example exhumation during plate divergence or syn-convergent exhumation, or the mechanism of subduction initiation, for example vertically forced initiation by gravitational sinking or horizontally forced initiation due to plate convergence. The Tibetan plateau is currently the highest continental plateau and its first-order geometry is well constrained. Spatial variations in topography and crustal thickness can be used to estimate horizontal forces per unit length from spatial variations in gravitational potential energy per unit area. Knowledge of forces and stresses is essential to understand geodynamic processes. However, maximal magnitudes of differential stresses occuring locally within the crust remain disputed and range from ca. 10 MPa to several hundreds of MPa. Deterministic mathematical modelling based on the fundamental laws of physics is one method to test different geodynamic hypotheses and quantify potential stress magnitudes. Here, we employ 2D petrological-thermo-mechanical numerical simulations to the Alpine orogeny to test the two hypotheses of horizontally forced subduction initiation and syn-convergent exhumation with a single simulation and with petrological and geochronological data. We use 3D mechanical numerical calculations for the Tibetan plateau, to quantify the impact of (i) a realistic double curvature of the Earth’s crust, (ii) the effective viscosity of the crust, (iii) the stress exponent of a power-law flow law and (iv) the plateau’s corner regions on the 3D crustal stress field.

description: The determination of the Ba abundance in globular cluster (GC) stars is a very powerful test to address several issues in the framework of multiple population scenarios. We measured the Ba content for a sample of more than 1200 stars in 15 Galactic GCs, using high-resolution FLAMES/Giraffe spectra. We found no variation in [Ba/Fe] ratios for different stellar populations within each cluster; this means that low-mass asymptotic giant branch stars do not significantly contribute to the intra-cluster pollution. Very interestingly, we obtained that the fraction of Ba-stars in first generation (FG) stars is close to the values derived for field stars ($\sim$2\%); on the other hand, second generation (SG) stars present a significant lower fraction. An independent and successful test, based on radial velocity variations among giant stars in NGC~6121, confirms our finding: the binary fraction among FG stars is about $\sim$12\% to be compared with $\sim$1\% of SG stars. This is an evidence that SG stars formed in a denser environment, where infant mortality of binary systems was particularly efficient.

description:
The strata of the Danubian Cretaceous Group reflect dynamic depositional conditions in a peri-continental setting at the northern margin of the Alpine Tethys. From the Middle Turonian onwards, tectonic inversion along the Franconian Lineament started, reflected by the deposition of coarse-grained and extremely immature siliciclastics of the continental, more than 466 m thick Hessenreuth Formation, comprising the mid-Middle Turonian–Middle Coniacian depositional sequences DS Tu 3–Co 2. The composite section studied consists of successions cored by the deep Friedersreuth 10/1990 borehole as well as several shallow boreholes and outcrops. The >63 m thick Glashütte Member below 312 m ASL is characterized by beige-pink, conglomeratic sandstones alternating with thin brick-red, argillaceous-silty soil horizons. The Parkstein Member (312–390 m ASL) is dominated by several-meters-thick, partly inversely graded sandstone packages, interbedded by a few thin carbonaceous silt and clay beds with plant debris. The tripartite Friedersreuth Member (390–562 m ASL) starts with a cyclic conglomeratic-brecciform debris-flow unit, followed by a chaotic mud-flow unit, and is capped by predominantly fine-grained, plant-rich siliciclastics. The uppermost ca. 153 m constitutes the Hesserberg Member, i.e., mica-rich, coarse conglomerates that include meter-scale boulders. These alluvial subunits can be correlated to the mixed marginal marine / continental succession of the Bodenwöhrer Senke, ca. 60 km in the south, and the neritic deposits around Regensburg–Kelheim. Palynoassemblages are dominated by angiosperm pollen of the Normapolles group. Below 515 m ASL, the Turonian marker Complexiopollis christae occurs, while above 555 m ASL, Minorpollis minimus characterizes the Coniacian.

description: (abridged) The ICM has been suggested to be buoyantly unstable in the presence of magnetic field and anisotropic thermal conduction. We perform first cosmological simulations of galaxy cluster formation that simultaneously include magnetic fields, radiative cooling and anisotropic thermal conduction. In isolated and idealized cluster models, the magnetothermal instability (MTI) tends to reorient the magnetic fields radially. Using cosmological simulations of the Santa Barbara cluster we detect radial bias in the velocity and magnetic fields. Such radial bias is consistent with either the inhomogeneous radial gas flows due to substructures or residual MTI-driven field rearangements that are expected even in the presence of turbulence. Although disentangling the two scenarios is challenging, we do not detect excess bias in the runs that include anisotropic thermal conduction. The anisotropy effect is potentially detectable via radio polarization measurements with LOFAR and SKA and future X-ray spectroscopic studies with the IXO. We demonstrate that radiative cooling boosts the amplification of the magnetic field by about two orders of magnitude beyond what is expected in the non-radiative cases. At z=0 the field is amplified by a factor of about 10^6 compared to the uniform magnetic field evolved due to the universal expansion alone. Interestingly, the runs that include both radiative cooling and anisotropic thermal conduction exhibit stronger magnetic field amplification than purely radiative runs at the off-center locations. In these runs, shallow temperature gradients away from the cluster center make the ICM neutrally buoyant. The ICM is more easily mixed in these regions and the winding up of the frozen-in magnetic field is more efficient resulting in stronger magnetic field amplification.

description:
Volcanoes are the most dynamic landforms, capable of changing their shape and environment in a matter of minutes, posing a significant threat to the environment and populations. While modern monitoring approaches can detect short-term changes, the long-term evolution is not well understood. Through the collection and photogrammetric processing of optical data, we can now reconstruct the precise topographies of volcanic edifices during the last decades to study different stages of volcanic development. By comparing the obtained topographies, we calculate volume flows, including eruptive and eroded materials, and evaluate the resulting geomorphic changes. Recent advances in technology and algorithms have opened unique opportunities for the collection and processing of photogrammetric data, allowing quantitative analysis of aerial photographs from the mid-last century to modern satellite and drone data. Here, we present ultra-high-resolution point clouds and digital elevation models to study long-term morphological and structural changes at volcanoes. In particular, the availability of archive ground and aerial stereo imagery from the last century allows us to look into the past and reconstruct volcanic activity in glaciated regions, and explore the complex interactions and geomorphic changes these regions undergo. We illustrate volcano-cryosphere interactions in Kamchatka and Iceland, highlighting the use of the method by pioneers since the beginning of the last century. We describe the main features of the use of photogrammetry in volcanological research and discuss possible further developments in terms of improved visualization and virtual reality application for educational purposes.

description: The forward-backward asymmetry (FBA) in top-pair production that was observed in 2008 gets a boost in a recent CDF publication. Not only has the FBA further been confirmed, but also distributional preferences are shown. Strikingly, the FBA is the most sizable in the large $M_{t\bar t}$ invariant mass region and in the large rapidity difference $|Δy|$ region. Here we used our previously proposed $t$-channel exchanged $W'$ boson to explain the new observations. We show that a new particle exchanged in the $t$-channel generically gives rise to such observations. Furthermore, we show that the proposed $W'$ can be directly produced in association with a top quark at the Tevatron and the LHC. We perform a signal-background analysis and show that such a $W'$ is readily observed at the Tevatron with a 10 fb$^{-1}$ luminosity and at the LHC-7 with just a 100 pb$^{-1}$ luminosity.

description:
Seismic activity and consistently high CO2 fluxes make the Eger Rift in Western Bohemia (CZ) a rare subsurface ecosystem and scientifically relevant location to study microbial behavior and assess how geologically derived compound are used in the deep subsurface. Studying microbial life in this ecosystem provides the opportunity to investigate how high CO2 levels and mineralogy influence microbial community composition and metabolic activity. Seismic activity in this region can also release H2, a process which may provide the basis for primary production through methanogenic archaea and should be explored.

To assess microbial processes associated with the Eger Rift subsurface we investigated diversity, community structure and metabolic attributes of bacterial and archaeal communities in drill core sediments and groundwater samples. We also analyzed the geochemical conditions in this subsurface system and studied the physiological responses of native Eger microbial communities to high CO2 via enrichments

Genomic analysis of sediment and water samples, covering depths between 17m and 230m, provided novel insights into a CO2 adapted microbial community. We detected strong Cyanobacteria and Proteobacteria signatures as well as unexpected archaeal diversity in sediments, and high abundances of acidophiles and sulfate reducers in water samples. Enrichment cultures from the recovered sediments suggested subsurface populations can actively utilize CO2 and H2, while reconstruction and annotation of MAGs provided insights into microbial processes driven by CO2.

Going forward our data will be used to further investigate cellular processes under high CO2 conditions and identify pathways and biomolecules which may be of industrial and biotechnological relevance.

It is used to show that theoretical predictions for two-dimensional flows with small diffusivity carry over to three dimensions even though the stretching properties differ significantly. The variance decay rate, scalar field structure, and time evolution of statistical moments confirm that there are two distinct regimes of scalar decay: a locally controlled regime, which applies when the domain size is comparable to the characteristic lengthscale of the velocity field, and a globally controlled regime, which when applies when the domain is larger. Asymptotic predictions for the variance decay rate in both regimes show excellent agreement with the numerical results. Consideration of both the forward flow and its time reverse makes it possible to compare the scalar evolution in flows with one or two expanding directions; simulations confirm the theoretical prediction that the decay rate of the scalar is the same in both flows, despite the very different scalar field structures.

description: One of the key predictions of the merger hypothesis for the origin of early-type (elliptical and lenticular) galaxies is that tidally-induced asymmetric structure should correlate with signatures of a relatively young stellar population. Such a signature was found by Schweizer and Seitzer (1992; AJ, 104, 1039) at roughly 4sigma confidence. In this paper, we revisit this issue with a nearly ten-fold larger sample of 0.01

description:
Hydrothermal systems offer significant potential for green energy and heat production. The Buntsandstein Formations provide aquifers that are applicable for hydrothermal heat (or power) production. The Geological Survey of Brandenburg (LBGR) will improve its data base on Middle Buntsandstein aquifers using machine learning algorithms on archived exploration data.

Data stored in the archive of the LBGR contains drilling information for some 200 boreholes penetrating the Buntsandstein Subgroup. The LBGR has access to some thousand 2D seismic profiles from exploration surveys, typically reaching the Zechstein Group or the deeper-lying sandstone aquifers in the Upper Rotliegend Subgroups.

Drilling logs such as gamma ray or density logs provide valuable information for stratification and petrophysical rock property analysis. Available drilling logs will be digitized, and machine learning algorithms will be trained on exemplary data sets such as drilling E Hr 1/68. Machine learning algorithms will help to stratify the Buntsandstein sections of the available drillings. The stratification based on machine learning is further validated on newly interpreted seismic and drilling results, such as the cores stored at the drilling core and sample archive of the LBGR. The base will be in consideration of depositional gaps and tectonics. Also, a well-to-seismic-tie is performed at selected locations, and synthetic seismic profiles are generated.

If possible, seismic lines are (semi-)automatically evaluated to identify Hardegsen, Detfurth, and Volpriehausen Formations. Interpretation results are integrated in a 3D-geological model to build a regional-scaled Buntsandstein model of Brandenburg, allowing parameterization and calculation of reservoir temperature or heat in place.

description: Abstract:
The purpose of the study was to evaluate the effectiveness of using a video model, graduated exposure (i.e., touch, smell, try, eat), and positive reinforcement to first increase food exploration, and then increase consumption of non-preferred foods in young children that exhibit food selectivity in a school setting. A multiple probe design across behaviors replicated across participants was used to evaluate the effectiveness of a treatment package. The treatment package consisted of a video model of each target behavior (touch, smell, try, eat) and positive reinforcement which included preferred foods and materials. The results indicated that the treatment package was effective in increasing the food exploration and consumption of non-preferred foods for one participant, and was inconclusive for the second participant.

description: Background: A protein intake above the recommended dietary allowance (RDA) (i.e., 0.8 g∙kgˉ¹∙dayˉ¹) might benefit muscle strength (MS) and skeletal muscle mass (SMM). However, whether a higher protein intake would benefit MS and SMM (depending on sex, age group, and physical activity level) at younger ages is still to be determined. Objective: To examine whether a protein intake above the RDA is associated with a higher MS and SMM depending on sex, age group, and physical activity level in young and middle-aged adults. Methods: A secondary data analysis from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 was conducted. We analyzed data from participants aged 20 to 59, with dietary intake (24 h dietary recall), combined handgrip strength (HGS), dual-energy x-ray absorptiometry-derived appendicular lean soft tissue (ALST), accelerometer-assessed physical activity, among other variables (n = 3406). The protein intake was categorized as <0.8, 0.8 to 1.0, 1.0 to 1.6, and ≥1.6 g∙kgˉ¹∙dayˉ¹. HGS and ALST were adjusted for BMI (HGS-BMI, and ALST-BMI, respectively). Physical activity was categorized as low, moderate, and high. The HGS-BMI and ALST-BMI were compared among the protein intake groups, setting the 0.8 to 1.0 g∙kgˉ¹∙dayˉ¹ group as the reference. This analysis was carried out for the whole sample, by sex (males, females), age group (young, middle-aged), physical activity level (low, moderate, high), and their corresponding 12 subgroups in one model adjusted for confounding variables per outcome variable. Results: Protein intake per day was positively associated with MS in almost all the subgroups (11 out of 12, p < 0.05), whereas it was associated with SMM in half of the subgroups (7 out of 12), mainly in males (5 out of 6). Overall, the proportional benefit observed with a higher protein intake was greater in MS (≈30% vs the reference group), and it began to be observed at lower doses (starting at 1.0 g∙kgˉ¹∙dayˉ¹) than in SMM (≈10% vs the reference group), which was evident above 1.6 g∙kgˉ¹∙dayˉ¹. Conclusions: A slightly high protein intake (>1.0 g∙kgˉ¹∙dayˉ¹) was associated with a higher MS, while higher protein amounts (≥1.6 g∙kgˉ¹∙dayˉ¹) would be necessary to observe a higher SMM.

description: The goal of this article is to study the discrepancy of the distribution of arithmetic sequences in arithmetic progressions. We will fix a sequence $\A=\{\a(n)\}_{n\geq 1}$ of non-negative real numbers in a certain class of arithmetic sequences. For a fixed integer $a\neq 0$, we will be interested in the behaviour of $\A$ over the arithmetic progressions $a \bmod q$, on average over $q$. Our main result is that for certain sequences of arithmetic interest, the value of $a$ has a significant influence on this distribution, even after removing the first term of the progressions.

title: Decoupled radiogenic Nd and Hf isotopes of clays reveal South Asian Monsoon control of silicate weathering intensity

description:
The weathering of silicate rocks removes CO2 from the atmosphere-ocean system on geological timescales but the time required for weathering intensity to respond to changes in climate is poorly constrained. The radiogenic isotopes of hafnium and neodymium are decoupled during silicate weathering with the isotopic composition of river clays being offset from bulk rocks. Here we examine the decoupled Nd-Hf isotopes of clays deposited in marine sediments from the northern Bay of Bengal near the mouth of the Ganga-Brahmaputra rivers. The sediment core (SO188 17286-1) covers the last 130 kyrs and has been used to study the past intensity of the South Asian Monsoon (SAM). The deviation of the Hf isotope compositions from the array defined by global river clays (ΔεHf clay), has a pattern of variability similar to the record of SAM intensity inferred from the reconstructed δ18O of seawater and δD of leaf waxes. These variations in silicate weathering intensity occur on timescales near 20 kyrs and appear to be paced by orbital precession. This suggests a strong, and rapid (on geological timescales), link between SAM hydroclimate and silicate weathering in this region. In contrast, changes in the source provenance of the clays as recorded by their Nd isotope signatures follow a glacial-interglacial pattern indicating either a sea level or global climate influence on changes in sediment transport to the shelf. This contrast demonstrates the great utility of ΔεHf clay to record changes in weathering intensity while directly accounting for shifts in sediment source provenance.
