Global Observational Estimates of Mesoscale Eddy‐Driven Quasi‐Stokes Velocity and Buoyancy Diffusivity

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Mesoscale eddies are a dominant reservoir of kinetic energy in the ocean and play an important role in the transport and stirring of tracers such as heat and carbon. These effects need to be parameterized in most ocean models. A number of studies have observationally quantified eddy effects, but most of these have focused on the diffusivity of

Unseen Experts of the Sea: Fishers' Local Ecological Knowledge Reveals Elasmobranch Hotspot Decline Around Curaçao, Dutch Caribbean

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 6, June 2025.
ABSTRACT Fishing pressure is the primary threat to coastal elasmobranch populations, and understanding its impact requires long‐term regional data—often lacking in complex, small‐scale fishery settings. This is the case for Curaçao, a southern Dutch Caribbean island with an unmonitored artisanal fishery where, according to anecdotes, elasmobranchs have

Population Dynamics of Ervilia castanea (Montagu, 1803) Hints at Evolutionary Processes Shaping North‐East Atlantic Insular Sandy Habitats

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Shallow‐water sandy habitats of volcanic oceanic islands are among the most geologically and ecologically dynamic marine habitats on Earth. We investigate the population genetic patterns of Ervilia castanea, an infaunal marine bivalve with a planktotrophic larvae inhabiting Macaronesian shallow‐water sandy habitats.

Differences between potassium and sodium incorporation in foraminiferal shell carbonate

open access: yesFrontiers in Marine Science
The isotopic and elemental composition of the fossil shells of foraminifera are often used for reconstructing past environments and climates. These so-called proxy relations are based on the effect of environmental conditions (e.g.

Alkenone Distributions and Hydrogen Isotope Ratios Show Changes in Haptophyte Species and Source Water in the Holocene Baltic Sea

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The Baltic Sea, a dynamic, marginal marine basin, experienced a number of large changes in salinity during the Holocene as a result of fluctuations in global and local sea level related to melting of glacial ice sheets and subsequent isostatic rebound ...
