Identifying conditions associated with outliers produced by three different chlorophyll fluorometers: A comparison of instrumentation and development of correction formulae

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Measurements of chlorophyll concentration reported by fluorometers (fChl) are used in environmental research and monitoring, as inputs to models, and in the interpretation of remote sensing data. Researchers and managers benefit from understanding how to interpret and ensure the accuracy of fChl data collected by in situ fluorometers. Although

Culturing the solitary ascidian Phallusia nigra in closed and open water systems for tropical environmental research

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Marine and coastal ecosystems have been undergoing dramatic shifts due to global environmental changes. The rise in seawater temperature, ocean acidification, hypoxia, eutrophication, and anthropogenic pollution severely affects marine organisms.

At‐sea intercomparison of a membrane‐based pCO2 sensor and a traditional showerhead equilibrator system on a Ship‐of‐Opportunity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The seawater partial pressure of carbon dioxide (pCO2) is an essential ocean variable needed to calculate air‐sea gas exchange and to identify marine carbon sinks and sources. Recent technological developments support autonomous pCO2 measurements with sensors that are smaller and cheaper. In July 2021, these differences were highlighted during
