Mudwave activity and current-controlled sedimentation in Powell Basin, northern Weddell Sea, Antarctica
Read more of: Mudwave activity and current-controlled sedimentation in Powell Basin, northern Weddell Sea, AntarcticaAn area of mudwave development has been identified from the northwestern Powell Basin, northern Weddell Sea, Antarctica. The wave-field is located near the base of the continental slope in water […]

Climate anomaly wave-train patterns linking southern low and high latitudes during South Pacific warm and cold events
Read more of: Climate anomaly wave-train patterns linking southern low and high latitudes during South Pacific warm and cold eventsAtmospheric wave-trains of climate anomalies are investigated as a candidate for linking low and high latitude atmospheric signals during Pacific Ocean warm (ENSO) and cold (La Niña) events. Study results, […]

Potential waves for relativistic electron scattering and stochastic acceleration during magnetic storms
Read more of: Potential waves for relativistic electron scattering and stochastic acceleration during magnetic stormsThe possibility of electron stochastic energization to relativisitic energies (≥ 1 MeV) via resonant wave-particle interactions during a magnetic storm is explored. The minimum electron energy Emin for cyclotron resonant […]

Predictive systems ecology
Read more of: Predictive systems ecologyHuman societies, and their well-being, depend to a significant extent on the state of the ecosystems that surround them. These ecosystems are changing rapidly usually in response to anthropogenic changes […]

Influence of anisotropy on velocity and age distribution at Scharffenbergbotnen blue ice area
Read more of: Influence of anisotropy on velocity and age distribution at Scharffenbergbotnen blue ice areaWe use a full-Stokes thermo-mechanically coupled ice-flow model to study the dynamics of the glacier inside Scharffenbergbotnen valley, Dronning Maud Land, Antarctica. The domain encompasses a high accumulation rate region […]

A 950 yr temperature reconstruction from Duckhole Lake, southern Tasmania, Australia
Read more of: A 950 yr temperature reconstruction from Duckhole Lake, southern Tasmania, AustraliaA lack of quantitative high resolution paleoclimate data from the Southern Hemisphere limits the ability to examine current trends within the context of long-term natural climate variability. This study presents […]

Understanding controls on rapid ice-stream retreat during the last deglaciation of Marguerite Bay, Antarctica, using a numerical model
Read more of: Understanding controls on rapid ice-stream retreat during the last deglaciation of Marguerite Bay, Antarctica, using a numerical modelUsing a one-dimensional numerical model of ice-stream flow with robust grounding-line dynamics, we explore controls on paleo-ice-stream retreat in Marguerite Bay, Antarctica, during the last deglaciation. Landforms on the continental […]

The effect of basal channels on oceanic ice-shelf melting
Read more of: The effect of basal channels on oceanic ice-shelf meltingThe presence of ice shelf basal channels has been noted in a number of Antarctic and Greenland ice shelves, but their impact on basal melting is not fully understood. Here […]

Observations of nitric oxide in the Antarctic middle atmosphere during recurrent geomagnetic storms
Read more of: Observations of nitric oxide in the Antarctic middle atmosphere during recurrent geomagnetic stormsWe report ground-based measurements of the polar middle atmosphere made using a 230-250 GHz passive microwave radiometer deployed at Troll station (72°01’S 02°32’E, L-shell of L = 4.8), Antarctica. Our observations show enhanced […]
