Linear trends in salinity for the World Ocean, 1955–1998 - Boyer - 2005 - Geophysical Research Letters - AGU Publications
A landmark 2005 study by Boyer, published in *Geophysical Research Letters*, revealed significant linear trends in global ocean salinity between 1955 and 1998. This peer-reviewed research, utilizing a substantial, calibrated dataset, identified widespread freshening across the North Atlantic and localized salinification in other regions. Understanding these longitudinal shifts is critical for refining climate models and assessing ocean circulation patterns.

MAELSTROM, a machine learning-based approach for stock assessment
Effective fisheries management demands a balance between resource utilization and ecological sustainability. Introducing Maelstrom, a novel, machine learning-based approach to stock assessment that addresses limitations of traditional models. This multispecies predictive model, built on neural networks, integrates fishery-dependent and -independent data to forecast stock abundance, even with shorter time series. Benchmarked against the established a4a framework, Maelstrom demonstrates comparable accuracy and highlights the value of considering ecological interactions.
Linear trends in salinity for the World Ocean, 1955–1998 - Boyer - 2005 - Geophysical Research Letters - AGU Publications
Analysis of historical ocean salinity data reveals significant trends. Boyer’s 2005 *Geophysical Research Letters* study, published by AGU, documents linear salinity decreases across the World Ocean between 1955 and 1998 – a critical climate indicator. This longitudinal assessment provides validated, empirical evidence of ocean freshening, potentially linked to increased precipitation and melting ice.
Disentangling the structure of an Antarctic plankton food web in bloom and non-bloom conditions
Understanding Antarctic marine ecosystems requires a clearer picture of plankton food web dynamics. This study, utilizing a network-based approach, disentangles these trophic relationships in Potter Cove under both phytoplankton bloom and non-bloom conditions, drawing on a 30-year longitudinal dataset. Findings reveal increased food availability for higher trophic levels during blooms, while microzooplankton play a crucial role in energy transfer during non-bloom periods.
