This paper considers the use of passive greenhouse apparatus in field experiments investigating the biological consequences of climate change. The literature contains many accounts of such experiments claiming relevance of […]
The original version of this glossary was published almost 20 years ago in the landmark volume Glaciated Continental Margins: An Atlas of Acoustic Images (Bell et al. 1997). For the […]
Submarine landslide scars, including the huge Hinlopen–Yermak slide-scar north of Svalbard (Fig. 1) (Vanneste et al. 2006; Winkelmann et al. 2006), are relatively common geomorphological features on glaciated continental margins. […]
Large ice streams that drain the West Antarctic Ice Sheet (WAIS) into the Amundsen Sea Embayment (ASE) are currently thinning, accelerating and retreating rapidly (e.g. Rignot et al. 2014). These […]
Within Earth’s ice sheets, fast-flowing ice streams are the principal components through which ice and sediment are discharged, accounting for c. 90% of the ice lost from the Antarctic today […]
Subglacial and ice-marginal landforms produced during the Last Glacial Maximum and subsequent regional deglaciation become progressively more buried, especially when postglacial sedimentation rates are high. Sub-bottom profiling is usually used […]
Ploughing by deep keels of floating icebergs is a common feature of high-latitude continental margins. Icebergs that have calved from glaciers or ice sheets produce a range of seafloor signatures, […]
Meltwater channels that have formed beneath glaciers and ice sheets have been observed on glaciated terrain, both terrestrial and submarine. Around Antarctica, channels incised into bedrock on the inner continental […]
The on-going introduction of non-native species to Antarctica due to expanding human activity presents an increasing threat to biodiversity. Under the Protocol on Environmental Protection to the Antarctic Treaty, all […]
Generally, Antarctica is considered to be an untouched area of the planet; however, the region’s ecosystems have been subject to increased human pressure for at least the past half-century. This […]
Whistler mode chorus emission is important in the acceleration of electrons and filling of the radiation belts at Jupiter. In this work chorus magnetic intensity levels (frequency-integrated spectral density, PB) […]
