; ; ; (Grundwasser, 2020-06-19)
Aufgrund deutlich erhöhter Wärmebedarfsdichten urbaner Räume besteht in besonderem Maße hier die Möglichkeit und Erfordernis, durch eine nachhaltige Wärmeversorgung und saisonale Wärmespeicherung im geologischen Untergrund ... -
Nutrient and Silicon Isotope Dynamics in the Laptev Sea and Implications for Nutrient Availability in the Transpolar Drift
; ; ; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-09-23)
Realistic prediction of the near‐future response of Arctic Ocean primary productivity to ongoing warming and sea ice loss requires a mechanistic understanding of the processes controlling nutrient bioavailability. To ... -
Nutrient co‐limitation in the subtropical Northwest Pacific
; ; ; ; ; ; ; ; ; ; ; ; ; (Limnology and Oceanography Letters, 2021-08-17)
Nutrients limiting phytoplankton growth in the ocean are a critical control on ocean productivity and can underpin predicted responses to climate change. The extensive western subtropical North Pacific is assumed to be ... -
Nutrient regulation of late spring phytoplankton blooms in the midlatitude North Atlantic
; ; ; ; ; (Limnology and Oceanography, 2019)
The duration and magnitude of the North Atlantic spring bloom impacts both higher trophic levels and oceanic carbon sequestration. Nutrient exhaustion offers a general explanation for bloom termination, but detail on which ... -
Nutzungsgeschichte, Zustand und Revitalisierung der Moore im Erzgebirge
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 32; 2002)Abstract: According to historical geological maps, the bogs on the German side of the Erzgebirge occupied approx. 6000 hectares at the end of the 19th century. Firstly, for the initial steps of a much needed, up-to-date ... -
Oberbodenabtrag: eine Methode zur großflächigen funktionellen Wiederherstellung von Niedermoorlebensräumen? – Ergebnisse einer Machbarkeitsstudie
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 45; 2015)Abstract: A pilot study was realized in 2013/2014 to investigate the restoration of degraded percolation mires by a large-scale top soil removal. Objectives and results of the study are presented. The project area is ... -
Oberer Rupelton, Schleichsand (Rupel) und Cyrenenmergel (tiefes Chatt) im Mainzer Becken - Können sie mikropaläontologisch definiert werden?
(Mainzer geowissenschaftliche Mitteilungen; 17. 1988)Die mikropaläontologische Bearbeitung einiger Bohrprofile im Mainzer Becken hat gezeigt, daß die Abfolge Oberer Rupelton-Schleichsand-Cyrenenmergel auf der Grundlage der bisherigen Annahmen nicht überall gliederbar ist. ... -
Oberflächenstruktur von Torf und Wasserbewegung auf der Oberfläche
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 48; 2018)Moorflächen sind auf den Kontinenten überall vorhanden. Aus Mooren lässt sich durch Entwässerung und Trocknung leicht der hochporöse Torfgewinnen. Torf ist ein natürliches und ungiftiges Rohmaterial, das wegen seiner ... -

Oblique Gravity Wave Propagation During Sudden Stratospheric Warmings
;; ; (Journal of Geophysical Research: Atmospheres, 2020)
Gravity waves (GWs) are important for coupling the mesosphere to the lower atmosphere during sudden stratospheric warmings (SSWs). Here, a minor SSW is internally generated in a simulation with the upper-atmosphere ... -
Oblique Propagation and Refraction of Gravity Waves Over the Andes Observed by GLORIA and ALIMA During the SouthTRAC Campaign
; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2023-05-22)
Abstract Gravity waves (GW) carry energy and momentum from the troposphere to the middle atmosphere ...

Observational Evidence for Multivariate Drought Hazard Amplifications Across Disparate Climate Regimes
; ; (Earth's Future, 2022-09-16)
Drought poses significant challenges to global water security in a warming world. A global‐scale synthesis of the multivariate drought risk considering interdependencies between drought attributes across disparate climate ... -
Observations and high-resolution simulations of convective precipitation organization over the tropical Atlantic
; ; (Quarterly Journal of the Royal Meteorological Society, 2020)
High-resolution simulations (grid spacing 2.5 km) are performed with ICON-LEM to characterize convective organization in the Tropics during August 2016 over a large domain ranging from northeastern South America, along the ... -
Observations of Gravity Wave Refraction and Its Causes and Consequences
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2023-02-06)
Horizontal gravity wave (GW) refraction was observed around the Andes and Drake Passage during the SouthTRAC campaign. GWs interact with the background wind through refraction and dissipation. This interaction helps to ... -
Observations of Laboratory and Natural Slow Slip Events: Hikurangi Subduction Zone, New Zealand
; ; ; ; ; Kopf, Achim J. (Geochemistry, Geophysics, Geosystems, 2020)
Slow slip events (SSEs) are recognized as an important component of plate boundary fault slip, and there is a need for laboratory friction data on natural samples to guide comparisons with natural SSEs. Here, we compile a ... -
Observations on Astraeospongium meniscum (Roemer, 1948) from the Silurian of western Tennessee; constructional morphology and palaeobiology of the Astraeospongiidae (Calcarea, Heteractinellidae)
Mehl, Dorte; (Berliner geowissenschaftliche Abhandlungen : Reihe E, 1996)
Astraeospongium is found to form secondary calcareous basal skeletons and thus may be attributed to the morphological grouping "coralline sponges". In A. meniscum, a bowl-shaped sponge with a massive skeleton of octactins, ... -
Observed and Simulated Variability of Droplet Spectral Dispersion in Convective Clouds Over the Amazon
; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-10-15)
In this study, the variability of the spectral dispersion of droplet size distributions (DSDs) in convective clouds is investigated. Analyses are based on aircraft measurements of growing cumuli near the Amazon basin, and ... -
