A RUpture‐Based detection method for the Active mesopeLagIc Zone (RUBALIZ): A crucial step toward rigorous carbon budget assessments

Limnology and Oceanography: Methods, Volume 21, Issue 1, Page 24-39, January 2023., 2023
Abstract Determining mesopelagic organic carbon budgets is essential to characterize the ocean's role as a carbon dioxide sink. This is because the biological processes observed in the mesopelagic zone are crucial for understanding the biological carbon pump. Yet, field assessments of carbon budgets are often unbalanced with the carbon demand exceeding

The Transformation and Export of Organic Carbon Across an Arctic River‐Delta‐Ocean Continuum

Journal of Geophysical Research: Biogeosciences, Volume 127, Issue 12, December 2022., 2022
Abstract The Arctic Ocean is surrounded by land that feeds highly seasonal rivers with water enriched in high concentrations of dissolved and particulate organic carbon (DOC and POC). Explicit estimates of the flux of organic carbon across the land‐ocean interface are difficult to quantify and many interdependent processes makes source attribution ...

Implementing subtype‐specific pre‐clinical models of breast cancer to study pre‐treatment aspirin effects

Cancer Medicine, Volume 11, Issue 20, Page 3820-3836, October 2022., 2022
The impact of aspirin as a chemo‐preventative has been under increasing scrutiny as time has passed. Here we present a study detailing the relatively minor impact of aspirin in breast cancer prevention and survival. While Aspirin has effects on the outgrowth of lymph vessels it does not improve overall survival in clinically relevant mouse models of ...

Revisiting the Ocean Color Algorithms for Particulate Organic Carbon and Chlorophyll‐a Concentrations in the Ross Sea

Journal of Geophysical Research: Oceans, Volume 126, Issue 8, August 2021., 2021
Abstract The Ross Sea is the most productive marginal sea in the Southern Ocean and plays an important role in carbon cycling. However, limited sampling of Chlorophyll‐a (Chl) and particulate organic carbon (POC) concentrations from research expeditions constrains our understanding of the biogeochemical processes there. Satellites provide a useful tool

Hydrology controls the carbon mass balance of a mountain lake in the eastern European Alps

Limnology and Oceanography, Volume 66, Issue 6, Page 2110-2125, June 2021., 2021
Abstract Lakes and streams in mountain regions are important contributors to carbon (C) fluxes. However, detailed carbon balances of the stream‐lake continuum are rare. Combining eddy covariance (EC) measurements of lake‐atmosphere net ecosystem CO2 exchange with measurements of fluvial C fluxes (dissolved organic C, DOC; particulate organic C, POC ...

Diel variations in cell division and biomass production of Emiliania huxleyi—Consequences for the calculation of physiological cell parameters

Limnology and Oceanography, Volume 65, Issue 8, Page 1781-1800, August 2020., 2020
Abstract Cell division of the coccolithophore Emiliania huxleyi and other phytoplankton typically becomes entrained to diel light/dark cycles under laboratory conditions, with division occurring primarily during dark phases and production occurring during light phases.
