High spatial‐resolution monitoring to investigate nitrate export and its drivers in a mesoscale river catchment along an anthropogenic land‐cover gradient
(Hydrological Processes, 2021-12-14)Nitrate monitoring is commonly conducted with low‐spatial resolution, only at the outlet or at a small number of selected locations. As a result, the information about spatial variations in nitrate export and its drivers ... -
Fuzzy map comparisons enable objective hydro‐morphodynamic model validation
(Earth Surface Processes and Landforms, 2021-11-18)Numerical modeling represents a state‐of‐the‐art technique to simulate hydro‐morphodynamic processes in river ecosystems. Numerical models are often validated based on observed topographic change in the form of pixel ... -
Holocene lake‐level evolution of Lake Tiefer See, NE Germany, caused by climate and land cover changes
(Boreas, 2021-11-17)Lake‐level reconstructions are a key tool in hydro‐climate reconstructions, based on the assumption that lake‐level changes primarily reflect climatic changes. Although it is known that land cover changes can affect ... -
Global vulnerability hotspots: differences and agreement between international indicator-based assessments
(Climatic Change, 2021-11-15)Climate change impacts and their consequences are determined not only by the intensity and frequency of different climatic hazards but also by the vulnerability of the system, society or community exposed. While general ... -
Climate change literacy and migration potential: micro-level evidence from Africa
(Climatic Change, 2021-11-06)While a growing literature studies the effects of climate change on international migration, still only relatively little is known about the individual mechanisms linking migration decisions to climate change. We argue ... -
Evolution of Sea Surface Hydrology Along the Western Australian Margin Over the Past 450 kyr
(Paleoceanography and Paleoclimatology, 2021-11-05)We collected a suite of core top samples during R/V Sonne Cruise SO257 in May 2017 along the southwestern front of the Indo‐Pacific Warm Pool (IPWP) to monitor the variability of Southern Hemisphere tropical and subtropical ... -
The Transpolar Drift Influence on the Arctic Ocean Silicon Cycle
(Journal of Geophysical Research: Oceans, 2021-11-03)During most of the year, diatom production in the ice‐covered Central Arctic Ocean (CAO) is limited by light availability and nutrient supply. Therefore, biological production is thought to be generally low, with higher ... -
Comprehensive analysis of chemical and biological problems associated with browning agents used in aquatic studies
(Limnology and Oceanography: Methods, 2021-10-28)Inland waters receive and process large amounts of colored organic matter from the terrestrial surroundings. These inputs dramatically affect the chemical, physical, and biological properties of water bodies, as well as ... -
Atmospheric Wind Biases: A Challenge for Simulating the Arctic Ocean in Coupled Models?
(Journal of Geophysical Research: Oceans, 2021-10-25)Many state‐of‐the‐art climate models do not simulate the Atlantic Water (AW) layer in the Arctic Ocean realistically enough to address the question of future Arctic Atlantification and its associated feedback. Biases ... -
Spatial and Temporal Variability in Concentration‐Discharge Relationships at the Event Scale
(Water Resources Research, 2021-10-13)The analysis of concentration‐discharge (C‐Q) relationships from low‐frequency observations is commonly used to assess solute sources, mobilization, and reactive transport processes at the catchment scale. High‐frequency ... -
Isotope hydrology and water sources in a heavily urbanized stream
(Hydrological Processes, 2021-10-06)Complex networks of both natural and engineered flow paths control the hydrology of streams in major cities through spatio‐temporal variations in connection and disconnection of diverse water sources. We used spatially ... -
Process‐Based Flood Risk Assessment for Germany
(Earth's Future, 2021-10-05)Large‐scale flood risk assessments are crucial for decision making, especially with respect to new flood defense schemes, adaptation planning and estimating insurance premiums. We apply the process‐based Regional Flood ... -
Submesoscale flows impact Agulhas leakage in ocean simulations
(Communications Earth & Environment, 2021-09-28)Agulhas leakage, the warm and salty inflow of Indian Ocean water into the Atlantic Ocean, is of importance for the climate-relevant Atlantic Meridional Overturning Circulation. South of Africa, the eastward turning Agulhas ... -
Sedimentological evidence for seiching in a swell-dominated headland-bay system: Table Bay, Western Cape, South Africa
(Geo-Marine Letters, 2021-09-18)Table Bay, South Africa, is a typical headland-bay system with a shoreline that can be described by a logarithmic spiral. A peculiarity and unique feature of Table Bay is the juxtaposition of Robben Island opposite its ... -
Volume Transport Time Series and Variability of the North Atlantic Eastern Boundary Current at Goban Spur
(Journal of Geophysical Research: Oceans, 2021-09-16)The Eastern Boundary Current is an essential part of the water mass exchange between the subtropical and subpolar North Atlantic. Here, we study the offshore branch of the European Shelf Current (ESC) over the Goban Spur ... -
Complex High‐ and Low‐Flow Networks Differ in Their Spatial Correlation Characteristics, Drivers, and Changes
(Water Resources Research, 2021-09-15)Hydrologic extremes such as floods and droughts are often spatially related, which increases management challenges and potential impacts. However, these spatial relationships in high and low flows are often overlooked in ... -
Is the soil moisture precipitation feedback enhanced by heterogeneity and dry soils? A comparative study
(Hydrological Processes, 2021-09-09)The interaction between the land surface and the atmosphere is a crucial driver of atmospheric processes. Soil moisture and precipitation are key components in this feedback. Both variables are intertwined in a cycle, that ... -
Hurricane Matthew in 2100: effects of extreme sea level rise scenarios on a highly valued coastal area (Palm Beach, FL, USA)
(Geo-Marine Letters, 2021-09-08)Sea-level rise represents a severe hazard for populations living within low-elevation coastal zones and is already largely affecting coastal communities worldwide. As sea level continues to rise following unabated greenhouse ... -
