Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.

Herbivore Diversity Helps Maintain Arctic Tundra Diversity
A long-term experiment in southwestern Greenland reveals that the presence of musk oxen and caribou helps stave off declines in Arctic tundra diversity brought on by climate change.
Understanding an Extreme Weather Event with Science and Local Knowledge
Researchers in Mexico integrate science and community knowledge to assess the ecological and social impact of an extreme frost.
An Open and Inexpensive ‘Fluxbot’ for Measuring Soil Respiration
An inexpensive system of automated gas sensors and open-source software, tested in a Kenyan savanna, will help democratize and expand science research on soil respiration.
Mosses Play Key Roles in Ecosystems from Tropics to Tundra
A global survey of mosses growing on soil found that the somewhat underappreciated plants cover a vast area and perform tasks such as sequestering carbon.
مراقبة تراكم الملوثات من المعادن الثقيلة في دلتا النيل
تُظهر نتائج تحاليل العينات أن إعادة استخدام مياه الصرف بدون معالجة والتوسع في إنشاء السدود يسبب زيادة تركيز المعادن الثقيلة الملوثة في دلتا النيل مما يهدد بشدة سلامة النظام البيئي والصحي والإنتاج الزراعي في مصر.
Tracking Heavy Metal Accumulation in the Nile Delta
Sediment measurements show that flow alterations and discharges are driving increasing concentrations of multiple heavy metals in the Nile Delta, threatening ecosystems, agriculture, and human health.
Suivie de l’accumulation des métaux lourds dans le Delta du Nil
Les analyses de sédiments montrent que la réutilisation de l’eau non traitée et la construction de barrages entraînent l’augmentation des concentrations de métaux lourds dans le Delta du Nil, menaçant gravement les écosystèmes, l’agriculture et la santé humaine.
Why Tropical Forests Are Important for Our Well-Being
Tropical forests play a critical role in supporting human well-being, food security, and the maintenance of biodiversity.
Glacial Ice Offers Polar Bears a Precarious Climate Refuge
An isolated polar bear population in southeastern Greenland survives in fjords, despite spotty sea ice. But this pocket of bears is not a sign of how the species could be saved.
