Seasonal Differences in the Attenuation of Polar Trace Organics in the Hyporheic Zone of an Urban Stream
; ; ; ; (Water Resources Research, 2022-01-20)
Attenuation of trace organic compounds (TrOCs) in a river occurs to a large extent in its hyporheic zone. A major part of the attenuation of polar TrOCs is of microbial origin. As microbial activity depends on temperature ... -
Seasonal dynamics and characterization of coccolithophore export production in two major upwelling regions - Cape Blanc (NW-Africa) & Chile (30 °S)
(Univ. Bremen, 2008)Coccolithophores, a major group of the nanophytoplankton, belong to the class Prymnesiophyceae.The cells of coccolithophores are typically surrounded by layer(s) of calcium carbonate plates, the coccoliths. Certain ... -
Seasonal Evolution of Light Transmission Distributions Through Arctic Sea Ice
; ; ; ; (Journal of Geophysical Research: Oceans, 2019)
Light transmission through sea ice is a critical process for energy partitioning at the polar atmosphere-ice-ocean boundary. Transmission of sunlight strongly impacts sea ice melting by absorption, as well as heat deposition, ... -
Seasonal Landslide Activity Lags Annual Precipitation Pattern in the Pacific Northwest
; (Geophysical Research Letters, 2022-09-26)
Seasonal variations in landslide activity remain understudied compared to recent advances in landslide early warning at hourly to daily timescales. Here, we learn the seasonal pattern of monthly landslide activity in the ... -

Seasonality of Organic Matter Degradation Regulates Nutrient and Metal Net Fluxes in a High Energy Sandy Beach
; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2020)
During seawater circulation in permeable intertidal sands, organic matter degradation alters the composition of percolating fluids and remineralization products discharge into surficial waters. Concurrently, coastal seawater ... -
Seaweed farming pressure affects seagrass and benthic macroalgae dynamics in Chwaka Bay (Zanzibar, Tanzania)
; ; ; ; (Regional Environmental Change, 2021-01-14)
Farming of Eucheuma denticulatum is a major activity in Zanzibar affecting seagrass ecosystems primarily through shading and trampling. The aim of this study was to test the impacts of shading and trampling during seaweed ... -
Sea‐Ice Forecasts With an Upgraded AWI Coupled Prediction System
; ; ; ; ; ; ; (Journal of Advances in Modeling Earth Systems, 2022-12-22)
A new version of the AWI Coupled Prediction System is developed based on the Alfred Wegener Institute Climate Model v3.0. Both the ocean and the atmosphere models are upgraded or replaced, reducing the computation time by ... -
Secondary Minerals Drive Extreme Lithium Isotope Fractionation During Tropical Weathering
; ; ; ; (Journal of Geophysical Research: Earth Surface, 2022-02-15)
Lithium isotopes are used to trace weathering intensity, but little is known about the processes that fractionate them in highly weathered settings, where secondary minerals play a dominant role in weathering reactions. ... -
Sectioning effects of porphyritic chondrules: Implications for the PP/POP/PO classification and correcting modal abundances of mineralogically zoned chondrules
; ; Sawatzki, Lena; Halbauer, Lucia; (Meteoritics & Planetary Science, 2020)
Mineralogically zoned chondrules are a common chondrule type in chondrites. They consist of olivine cores, surrounded by low-Ca pyroxene rims. By serial sectioning porphyritic chondrules from carbonaceous, ordinary, and ... -
