Fresh Phytoplankton Bloom Growth in the Fall and Its Control on Ocean Heating in the Pacific Arctic Region

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Delayed sea ice freeze‐up and decreased sea ice extent in the Pacific Arctic region have altered light availability in marine waters, extending the ice‐free season and increasing opportunities for photosynthetic activity and energy exchanges. This study investigates phytoplankton bloom progression during the fall using chlorophyll pigments and

Relative Sea‐Level Change, Tidal Evolution and Energy Dissipation Across the Patagonian Shelf Since the Last Glacial Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Tides play a key role in regulating shelf‐sea environments, influencing sediment dynamics, habitat distribution, long‐term carbon burial, coastal hazards, and water quality, with important socio‐economic consequences. Yet the long‐term evolution of shelf sea tides in response to sea‐level change remains poorly understood. We have developed the

Extreme Value Analysis of Solar Green‐Line Corona During the Time Interval 1939–2025

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Predicting the probability of extreme solar events is critical to understanding how to mitigate risks associated with space weather disasters, as their occurrence can pose a threat to life and infrastructure on Earth or in near‐Earth orbit. In the present study, extreme value theory is applied to the daily modified coronal index (MCI) for the ...

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1656-1676, April 2026.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Climatic Stress Versus Anthropogenic Degradation: An Ecohydrological Perspective on the Drivers of Net Primary Productivity in a Seasonally Dry Tropical Forest

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Water‐limited ecosystems play a fundamental role in the global carbon cycle, yet they have been increasingly affected by pressures from aridification and land‐use and land‐cover change. The Caatinga, the largest seasonally dry tropical forest in South America, exhibits strong ecohydrological coupling resulting from centuries of adaptation, in ...

Structural Quality of an Ultisol Under Long‐Term Different Tillage Systems and Cover Crops With Corn in Northeast Brazil

Soil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Dual‐purpose corn cropping is a widespread and economically important agricultural activity in Brazilian rural areas. The objective of this work was to study the structural quality of a dystrophic Red‐Yellow Ultisol under different tillage systems, previous crops and inoculant treatments, and its relationship with corn yield.

Espectro solar: refração da luz

, 2018
A Astronomia é uma Ciência com identidade própria e que reúne quase todas as áreas do conhecimento, sendo assim, pode ser trabalhada de modo interdisciplinar na escola e deve se fazer presente no Ensino Fundamental, uma vez que é na escola onde se tem o acesso mais fácil ao conhecimento para a maioria dos brasileiros. Desse modo, vimos a necessidade de
