Proxy-based reconstructions and climate model simulations of Holocene global annual mean temperatures exhibit divergent trends, leading to the well-known “Holocene temperature conundrum (HTC)”. This discrepancy is most pronounced in the […]
Blue Carbon (BC) refers to Nature-Based Solutions in marine environments that aim to reduce greenhouse gases through carbon sequestration using natural processes. Much of the BC focus to date has […]
A major natural route of dispersal to Antarctica is often assumed to be atmospheric transport, although few studies have documented this in detail. Aerial dispersal to Antarctica is very challenging […]
Hypoxic (O2 < 60 μmol kg−1) waters are found below 27% of the ocean surface and are predicted to expand in the near future; however, the organic carbon cycle in […]
Sudden Stratospheric Warmings (SSW) and Elevated Stratopause (ES) events are mid-to-high latitudinal, atmospheric wave-driven phenomena leading to significant changes in wind, temperatures, and vertical mass transport, especially at stratospheric and […]
The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat […]
For years, a main focus of ecological research has been to better understand the complex dynamical interactions between species which comprise food webs. Using the connectance properties of a widely […]
Background and Methods: We assessed the prokaryotic and eukaryotic diversity present in non-vegetated and vegetated soils on King George Island, Maritime Antarctic, in combination with measurements of carbon dioxide fluxes. […]
We present Bedmap3, the latest suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60 °S. Bedmap3 incorporates and […]
Phytoplankton play a pivotal role as the primary producers in polar marine ecosystems. Despite evidence suggesting that production rates and loss factors vary from year to year, and thus drive […]
The retreat of the Antarctic Ice Sheet is conventionally attributed to increased ocean melting of ice shelves, potentially enhanced by internal instability from grounding lines near retrograde bed slopes. Ocean […]
Sea-ice floating in the Arctic ocean is a constantly moving, growing and melting layer. The seasonal cycle of sea-ice volume has an average amplitude of or 9 trillion tonnes of […]
