The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

River algal blooms can be estimated by remote sensing reflectance

open access: yesEnvironmental Research Letters
River eutrophication is difficult to diagnose and estimate quantitatively because of its complex degradation mechanism in large river systems. Conventional monitoring and modeling methods are limited to accurately revealing the evolution process and ...

Harmful algal blooms (HABs) status of South Korea in the past 20 years

open access: yes, 2018
Marine harmful algal blooms (HABs) are a growing environmental problem globally and have serious impacts on public health, aquatic organisms, and aquaculture industries.

Quantifying Viral Lysis in Microalgae Using Cell‐Free rRNA

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Cell‐free ribosomal RNA (rRNA) dissolved in seawater provides a quantitative proxy for viral lysis in microeukaryotic phytoplankton. Incubation experiments with two distinct host–virus systems revealed marked increases in cell‐free rRNA production per cell, a proxy for lytic mortality, reaching up to 46‐ and 302‐fold relative to noninfected controls ...

About harmful algal blooms [PDF]

open access: yes
Algae are vitally important to marine and fresh-water ecosystems, and most species of algae are not harmful. However, a harmful algal bloom (HAB) can occur when certain types of microscopic algae grow quickly in water, forming visible patches that may ...

Multitechnique Physicochemical Characterization of Horse Hoof Trimmings as Sustainable and Untapped Keratin Source

open access: yesChemistryOpen, Volume 15, Issue 10, October 2026.
Horse hoof trimmings, cruelty‐free and traceable keratin‐rich waste, were characterized for particle size, morphology, thermal stability, composition and metal contamination. Results show a high higher‐heating value and promising upcycling paths for energy and materials, but variable metal contamination (shoeing‐ and milling‐dependent) requires ...

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

open access: yesEnvironmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

Bacterial Contribution to Hydrogen Peroxide Decomposition in Lake Erie Cyanobacterial Harmful Algal Bloom Communities Is Dependent on Bloom Stage

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
A seasonal time series metatranscriptome dataset suggests that neutralising hydrogen peroxide in Microcystis blooms requires a complex division of labour that is further complicated by seasonality and bloom development. ABSTRACT Cyanobacterial harmful algal blooms (cHABs) are expanding globally and often involve toxin‐producing species such as ...

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 949-962, October 2026.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.
