Reconstructing Depositional Rates and Their Effect on Paleoenvironmental Proxies: The Case of the Lau Carbon Isotope Excursion in Gotland, Sweden
; ; Grohganz, M.; ; Vandenbroucke, T. R. A.; Munnecke, A. (Paleoceanography and Paleoclimatology, 2020-12-19)
Variations in depositional rates affect the temporal depositional resolutions of proxies used for paleoenvironmental reconstructions; for example, condensation can make reconstructed environmental changes appear very abrupt. ... -

(Journal of Seismology, 2021-06-03)Archaeological structures built across active faults and ruptured by earthquakes have been used as markers to measure the amount of displacement caused by ground motion and thus to estimate the magnitude of ancient ... -
Reconstruction of oceanic currents and climate change in the Transkei Basin, South African gateway
(Univ. Bremen, 2007)Reflection seismics, sediment drifts, bottom currents. - The region south of South Africa has been a crucial gateway for large scale Thermohaline Circulations since late Eocene times. Here, three of the most important ... -
Reconstruction of the Basin‐Wide Sea‐Level Variability in the North Sea Using Coastal Data and Generative Adversarial Networks
Zhang, Zeguo;; (Journal of Geophysical Research: Oceans, 2020-12-03)
We present an application of generative adversarial networks (GANs) to reconstruct the sea level of the North Sea using a limited amount of data from tidal gauges (TGs). The application of this technique, which learns how ... -
Reconstruction of the Phanerozoic tectono-thermal history of central and southern Madagascar, based on fission track thermochronology
(Univ. Bremen, 2004)Madagascar, Gondwana, thermochronology. - Titanite and apatite fission track (FT) thermochronology on 127 basement and 18 sedimentary rock samples from central and southern Madagascar record a complex cooling and denudation ... -
Reconstruction of the primary energy spectrum from fluorescence telescope data of the Pierre Auger observatory
(Univ. Wuppertal, 2007)Mit dem Pierre Auger Experiment wird zur Zeit das größte Luftschauerexperiment betrieben. Es befindet sich noch im Aufbau und die finale Konzeption sieht zwei Detektionsstandorte in den USA und Argentinien vor, um somit ... -
Reconstruction of the sedimentary history offshore NW Africa - application of core-logging tools

Record summers in Europe: Variations in drought and heavy precipitation during 1901–2018
; ; ; (International Journal of Climatology, 2022-03-04)
During the last 20 years some very hot and dry summers affected Europe, resulting in regionally record‐breaking high temperature or low precipitation values. Long‐term changes of such extremely hot and dry summers are of ... -
Recordings of Fast Paleomagnetic Reversals in a 1.2 Ma Greigite-Rich Sediment Archive From Lake Ohrid, Balkans
; ; ; ; (Journal of Geophysical Research: Solid Earth, 2019)
State-of-the-art paleoclimate research strongly depends on the availability of time-equivalent markers as chronological control to disentangle interrelationships in the climate system from regional to global scale. Geomagnetic ... -
Recycling and Burial of Biogenic Silica in an Open Margin Oxygen Minimum Zone
; ; ; Scholz, F.; Schroller‐Lomnitz, U.; Wallmann, K.; ; ; Plass, A.; ; ; Sommer, S. (Global Biogeochemical Cycles, 2021-02-17)
An extensive data set of biogenic silica (BSi) fluxes is presented for the Peruvian oxygen minimum zone (OMZ) at 11°S and 12°S. Each transect extends from the shelf to the upper slope (∼1,000 m) and dissects the permanently ... -
