The abundance of both heterotrophic nanoflagellates (HNAN) and bacterioplankton in a large (9km2) ultraoligotrophic Antarctic lake (Crooked Lake) were investigated from December 1992 until November 1993. HNAN abundance peaked in […]
The first deep-tow boomer survey on the Antarctic continental margin has revealed relict subglacial deltas on the outer continental shelf off the Antarctic Peninsula. Progradation of subglacial deltas is thought […]
1. Passive greenhouse apparatus is commonly used to investigate the in situ biological response of terrestrial communities to global warming. 2. Although close conformity of greenhouse treatment effects to general […]
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 […]
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, […]
