Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?
Limnology and Oceanography: Methods, EarlyView.Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Contribution of ultrafine particles to alkalinity in a limestone‐treated waterbody
Limnology and Oceanography: Methods, EarlyView.Abstract While it is well recognized that suspended particles can bias titration‐based total alkalinity (TA), whether addition of minerals for alkalinity enhancement introduces systematic TA artifacts remains poorly quantified. To address this gap, we quantified the contribution of ultrafine particles (< 0.2 μm) to TA titration introduced by limestone (

Geophysical Research LettersThe ocean carbon reservoir controls atmospheric carbon dioxide (CO2) on millennial timescales. Radiocarbon (14C) anomalies in eastern North Pacific sediments suggest a significant release of geologic 14C‐free carbon at the end of the last ice age but ...

Quantifying coastal ocean anthropogenic carbon changes and their uncertainties
Limnology and Oceanography: Methods, EarlyView.Abstract Despite recent progress in quantifying anthropogenic carbon (Canth) in global oceans, coastal regions remain understudied due to methodological and observational challenges. Here, we develop and generalize a Regional rEgression–based Coastal Anthropogenic carbon estimation algorithm (RECA) designed specifically for coastal environments ...

Ocean Alkalinity Enhancement Data Management Protocol
The OAE Data Management Protocol outlines recommendations for producing consistent data and metadata for Ocean Alkalinity Enhancement (OAE) research projects. With broad adoption, this protocol will make it possible to compare and interpret field research and more quickly advance our understanding of the field.In collaboration with Submarine ...
