The Impact of CO2 and Climate State on Whether Dansgaard–Oeschger Type Oscillations Occur in Climate Models
Read more of: The Impact of CO2 and Climate State on Whether Dansgaard–Oeschger Type Oscillations Occur in Climate ModelsGreenland ice core records feature Dansgaard–Oeschger (D-O) events, which are abrupt warming episodes followed by gradual cooling during ice age climate. The three climate models used in this study (CCSM4, […]

The deglacial history of 79N glacier and the Northeast Greenland Ice Stream
Read more of: The deglacial history of 79N glacier and the Northeast Greenland Ice StreamThe Northeast Greenland Ice Stream (NEGIS) is the main artery for ice discharge from the northeast sector of the Greenland Ice Sheet (GrIS) to the North Atlantic. Understanding the past, […]

Twenty‐thousand‐year gap between deglaciation and peat formation on sub‐Antarctic Marion Island attributed to climate and sea level change
Read more of: Twenty‐thousand‐year gap between deglaciation and peat formation on sub‐Antarctic Marion Island attributed to climate and sea level changeRadiocarbon dating of basal peats has been a key factor in determining minimum ages for deglaciation on sub-Antarctic islands. On Marion Island, peat bogs dominate the landscape below 300 m a.s.l., […]

Variability in Zoobenthic Blue Carbon storage across a Southern Polar Gradient
Read more of: Variability in Zoobenthic Blue Carbon storage across a Southern Polar GradientThe seabed of the Antarctic continental shelf hosts most of Antarctica’s known species, including taxa considered indicative of vulnerable marine ecosystems (VMEs). Nonetheless, the potential impact of climatic and environmental […]

Assessment of the southern polar and subpolar warming in the PMIP4 last interglacial simulations using paleoclimate data syntheses
Read more of: Assessment of the southern polar and subpolar warming in the PMIP4 last interglacial simulations using paleoclimate data synthesesGiven relatively abundant paleo-proxies, the study of the last interglacial (LIG, ∼ 129–116 000 years ago, ka) is valuable to understanding the responses and feedback of the Southern Ocean and Antarctica in […]

Population genetics of the deep-sea acorn barnacle Bathylasma hirsutum (Hoek, 1883) and the first report of its affiliation with a hydrothermal vent field
Read more of: Population genetics of the deep-sea acorn barnacle Bathylasma hirsutum (Hoek, 1883) and the first report of its affiliation with a hydrothermal vent fieldConfined by the Mid-Atlantic Ridge and the European continental shelf, the deep-sea acorn barnacle Bathylasma hirsutum (Hoek, 1883) lives in the northeast Atlantic deep sea where it has been frequently […]

Tipping point in ice-sheet grounding-zone melting due to ocean water intrusion
Read more of: Tipping point in ice-sheet grounding-zone melting due to ocean water intrusionMarine ice sheets are highly sensitive to submarine melting in their grounding zones, where they transition between grounded and floating ice. Recently published studies of the complex hydrography of grounding […]

South Georgia marine productivity over the past 15 ka and implications for glacial evolution
Read more of: South Georgia marine productivity over the past 15 ka and implications for glacial evolutionThe subantarctic islands of South Georgia are located in the Southern Ocean, and they may be sensitive to future climate warming. However, due to a lack of well-dated subantarctic palaeoclimate […]
