Diurnal Variability of Submesoscale Chlorophyll‐a Fronts Revealed by Hourly Geostationary Satellite Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The detection of submesoscale fronts is critical for understanding physical‐biological interactions and ecosystem variability. This study characterizes the diurnal variability of chlorophyll‐a (Chl‐a) fronts using hourly data from the geostationary satellite GK‐2B/GOCI‐II in the East/Japan Sea.

Automatic area estimation of algal blooms in water bodies from UAV images using texture analysis

open access: yesWater Science and Engineering
Algal blooms, the spread of algae on the surface of water bodies, have adverse effects not only on aquatic ecosystems but also on human life. The adverse effects of harmful algal blooms (HABs) necessitate a convenient solution for detection and ...

Long‐term perceptions of freshwater anglers about abandoned, lost or discarded fishing gear during their fishing careers

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Recreational freshwater anglers in Hungary were surveyed to assess the scale, causes, and impacts of abandoned, lost or discarded fishing gear (ALDFG). Based on 416 responses, we estimate that 7–11 million items of fishing gear are lost annually, amounting to over 40,000 tons by 2050 if current trends continue.

Misplaced fears? What the evidence reveals of the ecological effects of tidal power generation

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Marine energy (tidal range and stream/flow) is a dependable and clean power source that stands out as a compelling alternative to fossil fuels. Despite widespread concerns surrounding the ecological effects of tidal energy infrastructure, we find few of these are substantiated by evidence or long‐term monitoring of existing tidal power projects.

Measures to Control Harmful Algal Blooms

open access: yes, 2009
Harmful algal blooms (HABs) occur globally and are caused by different species of microalgae. They can be harmful by producing toxins or by the rapid increase in biomass often leading to discoloration and hypoxic conditions. Toxins accumulating in shellfish and fish can cause shellfish poisoning in humans, major economical losses, especially damage to ...
