Trends in the land and ocean carbon uptake
Only about 45% of the total CO2 emitted from fossil fuel burning and land use change stayed in the atmosphere on average during the past few decades. The remaining CO2 […]

Breeding latitude drives individual schedules in a trans-hemispheric migrant bird
Read more of: Breeding latitude drives individual schedules in a trans-hemispheric migrant birdDespite clear benefits of optimal arrival time on breeding grounds, migration schedules may vary with an individual bird’s innate quality, non-breeding habitat or breeding destination. Here, we show that for […]

Impacts of the oceans on climate change
Read more of: Impacts of the oceans on climate changeThe oceans play a key role in climate regulation especially in part buffering (neutralising) the effects of increasing levels of greenhouse gases in the atmosphere and rising global temperatures. This […]

Thermal dependency of burrowing in three species within the bivalve genus Laternula: a latitudinal comparison
Read more of: Thermal dependency of burrowing in three species within the bivalve genus Laternula: a latitudinal comparisonThe upper thermal limits for burrowing and survival were compared with micro-habitat temperature for anomalodesmatan clams: Laternula elliptica (Antarctica, 67A degrees S); Laternula recta, (temperate Australia, 38A degrees S) and […]

Late Pliocene-Pleistocene Antarctic climate variability at orbital and suborbital scale: ice sheet ocean and atmospheric interactions
Read more of: Late Pliocene-Pleistocene Antarctic climate variability at orbital and suborbital scale: ice sheet ocean and atmospheric interactionsContinental margin drill core and seismic data indicate that between 3.0 and 2.5 Ma, high-latitude climate cooling drove both the West and East Antarctic Ice Sheets towards their present expanded […]

Antarctic winter tropospheric warming – the potential role of polar stratospheric clouds, a sensitivity study
Read more of: Antarctic winter tropospheric warming – the potential role of polar stratospheric clouds, a sensitivity studyOver the last 30 years, Antarctic mid-tropospheric temperatures in winter have increased by 0.5 K per decade, the largest regional tropospheric warming observed. Over this period, amounts of polar stratospheric […]

Middle Miocene to Pliocene history of Antarctica and the Southern Ocean
Read more of: Middle Miocene to Pliocene history of Antarctica and the Southern OceanThis chapter explores the Middle Miocene to Pliocene terrestrial and marine records of Antarctica and the Southern Ocean. The structure of the chapter makes a clear distinction between terrestrial and […]

Cenozoic climate history from seismic reflection and drilling studies on the Antarctic continental margin
Read more of: Cenozoic climate history from seismic reflection and drilling studies on the Antarctic continental marginSeismic stratigraphic studies and scientific drilling of the Antarctic continental margin have yielded clues to the evolution of Cenozoic climates, depositional paleoenvironments and paleoceanographic conditions. This paper draws on studies […]

Nitrogen fixation in the western equatorial Pacific: Rates, diazotrophic cyanobacterial size class distribution, and biogeochemical significance
Read more of: Nitrogen fixation in the western equatorial Pacific: Rates, diazotrophic cyanobacterial size class distribution, and biogeochemical significanceA combination of 15N2 labeling, Tyramide Signal Amplification–Fluorescent in Situ Hybridization (TSA-FISH) assay, and chemical analyses were performed along a trophic gradient (8000 km) in the equatorial Pacific. Nitrogen fixation […]
