Quantifying the influence of snow over sea ice morphology on L-band passive microwave satellite observations in the Southern Ocean

Autor: L. Zhou, J. Stroeve, V. Nandan, R. Willatt, S. Xu, W. Zhu, S. Kacimi, S. Arndt, Z. Yang

Publikováno v: The Cryosphere, Vol 18, Pp 4399-4434 (2024)

Antarctic snow on sea ice can contain slush, snow ice, and stratified layers, complicating satellite retrieval processes for snow depth, ice thickness, and sea ice concentration. The presence of moist and brine-wetted snow alters microwave snow emiss

Are tinnitus burden and tinnitus exacerbation after cochlear implantation influenced by insertion technique, array dislocation, and intracochlear trauma?

Autor: F. Everad, R. L. Beck, A. Aschendorff, A. K. Rauch, Leonie Fries, S. Arndt, M. C. Ketterer

Publikováno v: Frontiers in Neurology, Vol 15 (2024)

IntroductionAlthough numerous studies suggest that cochlear implantation (CI) generally alleviates the overall burden of tinnitus, certain patients experience tinnitus exacerbation following CI. The exact cause of this exacerbation is still uncertain

Optimized fertilization using online soil nitrate data

Autor: Y. Yekutiel, Y. Rotem, S. Arnon, O. Dahan

Publikováno v: SOIL, Vol 10, Pp 335-347 (2024)

A new soil nitrate monitoring system that was installed in a cultivated field enabled us, for the first time, to control the nitrate concentration across the soil profile. The monitoring system was installed in a full-scale agricultural greenhouse se

From snow accumulation to snow depth distributions by quantifying meteoric ice fractions in the Weddell Sea

Autor: S. Arndt, N. Maaß, L. Rossmann, M. Nicolaus

Publikováno v: The Cryosphere, Vol 18, Pp 2001-2015 (2024)

Year-round snow cover is a characteristic of the entire Antarctic sea ice cover, which has significant implications for the energy and mass budgets of sea ice, e.g., by preventing surface melt in summer and enhancing sea ice growth through extensive

Evaluating modelled tropospheric columns of CH4, CO, and O3 in the Arctic using ground-based Fourier transform infrared (FTIR) measurements

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 1079-1118 (2024)

This study evaluates tropospheric columns of methane, carbon monoxide, and ozone in the Arctic simulated by 11 models. The Arctic is warming at nearly 4 times the global average rate, and with changing emissions in and near the region, it is importan

Assessing global-scale organic matter reactivity patterns in marine sediments using a lognormal reactive continuum model

Autor: S. Xu, B. Liu, S. Arndt, S. Kasten, Z. Wu

Publikováno v: Biogeosciences, Vol 20, Pp 2251-2263 (2023)

Organic matter (OM) degradation in marine sediments is largely controlled by its reactivity and profoundly affects the global carbon cycle. Yet, there is currently no general framework that can constrain OM reactivity on a global scale. In this study

Subsea permafrost organic carbon stocks are large and of dominantly low reactivity

Autor: F. Miesner, P. P. Overduin, G. Grosse, J. Strauss, M. Langer, S. Westermann, T. Schneider von Deimling, V. Brovkin, S. Arndt

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-12 (2023)

Abstract Subsea permafrost carbon pools below the Arctic shelf seas are a major unknown in the global carbon cycle. We combine a numerical model of sedimentation and permafrost evolution with simplified carbon turnover to estimate accumulation and mi

A VEGF-A splice variant defective for heparan sulfate and neuropilin-1 binding shows attenuated signaling through VEGFR-2

Autor: S. Cébe Suarez, S. Arn, U. Hoffmann, J. Wood, C. Manlius, A. Bogucki, Michel Pieren, Kurt Ballmer-Hofer, L. Cariolato

The development of functional blood and lymphatic vessels requires spatio-temporal coordination of the production and release of growth factors such as vascular endothelial growth factors (VEGFs). VEGF family proteins are produced in multiple isoform
