Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Antarctic krill, Euphausia superba, is an important species in the Southern Ocean and is vulnerable to climate change. We studied the carbon sources for krill—specifically pelagic and ice‐associated (sympagic) particulate organic matter (POM), representing phytoplankton and sea‐ice algae, respectively—during March 2019 across three distinct ...

Ontogenetic changes in the feeding strategy of Lepidonotothen nudifrons (Pisces, Nototheniidae) off the South Shetland Islands and the Antarctic Peninsula

Polar Research, 2017
The diet and feeding strategy of Lepidonotothen nudifrons off the South Shetland Islands and the Antarctic Peninsula, as well as their variation in relation to ontogenetic stage (juvenile–adult) and sampling area, were determined by stomach contents ...

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 535-550, July/September 2026.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Antarctic Snowfall Patterns and Trends: A Regional Analysis Across Multiple Data Sets

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Snowfall is the dominant positive component of the Antarctic surface mass balance (SMB) and a key factor regulating global sea level. However, substantial uncertainty remains in its spatial distribution and long‐term variability due to sparse in situ observations and retrieval challenges over polar ice sheets.

Warm Surface Waters Dominate Melting of the Denman‐Shackleton Ice Shelf System

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The ocean dynamics controlling the melting of the Denman‐Shackleton ice shelf system are investigated using a high‐resolution regional ocean‐sea ice‐ice shelf model. Our results show that basal meltwater production exhibits strong seasonal variability, driven by the ocean heat supply toward the ice shelf system, and occurs through two distinct

Weakening Tropical West Pacific Ascent Strength Reduces East Pacific Low Clouds via Lower Free‐Tropospheric Moisture Convergence

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Low clouds (LC) are the largest source of uncertainty in the climate response to increased CO2 ${\text{CO}}_{2}$ in global climate models. This is due to the multitude of factors that affect their behavior and how these are characterized across models.

Dynamic Deglacial Evolution of Interior Seaways and Ice Streams in the Weddell Sea Embayment

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Improving our understanding of Antarctic glacial dynamics is essential for accurately predicting ice sheet behavior and its contribution to global sea level rise under future climate scenarios. The Weddell Sea Embayment, which channels ice from East Antarctica, West Antarctica, and the Antarctic Peninsula into the Filchner‐Ronne Ice Shelf, is ...

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

South American fire activity in spring is linked to Antarctic sea ice variability

Communications Earth & Environment
Fires in South America exert substantial social, economic, and environmental impacts, and are becoming more severe. While tropical oceanic variability is widely recognized as a key driver of fire-conducive conditions, potential influences from mid- and ...
