Marine heatwaves are shaping the vertical structure of phytoplankton in the global ocean

Communications Earth & Environment
Marine heatwaves, characterized by extremely high ocean temperatures, significantly impact marine ecosystems. To date, the vertical structure of phytoplankton responses to marine heatwaves remains poorly understood.

Irreversible phytoplankton community shifts over Subpolar North Atlantic in response to CO₂ forcing [PDF]

Earth System Dynamics
Marine phytoplankton play a crucial role in the ocean's food web, marine ecosystems, and the carbon cycle. Their responses to external forcing vary across phytoplankton species, and phytoplankton community shifts can have important implications for their

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Mesoscale Oceanographic Processes Drive the Seasonal Abundance of the Seabob Shrimp Xiphopenaeus spp. on the Eastern Brazilian Shelf

Fisheries Oceanography, EarlyView.
ABSTRACT The seabob shrimp (Xiphopenaeus spp.) is a primary fishery resource in Brazil, with considerable economic and social importance along the coast. While environmental drivers of its life cycle are well‐documented for southeastern and southern populations, the factors modulating populations in the Eastern Brazilian Shelf remain poorly understood,

Marine Phytoplankton Extremes and Compound Extreme Events Have the Potential to Be Predicted Multiple Months in Advance

Geophysical Research Letters
Global marine primary producers, phytoplankton, are the base of the marine food web and vary on short timescales, characterized by seasonal blooms. There is growing concern about the occurrence of short‐term extreme events in phytoplankton abundance ...

Dynamics of phytoplankton communities in the Baltic Sea: insights from a multidimensional analysis of pigment and spectral data: part II, spectral dataset

Frontiers in Marine Science
The use of hyperspectral satellite missions opens new opportunities for integrated approaches to the study of phytoplankton communities. The Baltic Sea, with its distinct mixture of marine and freshwater characteristics, is a natural laboratory for ...

Phytoplankton adaptation to steady or changing environments affects marine ecosystem functioning [PDF]

Biogeosciences
Global warming poses a major threat to marine ecosystems, which fulfill important functions for humans and the climate. Ecosystem models are therefore increasingly used to estimate future changes in the functioning of marine ecosystems.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

Fisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...
