Surging glaciers in Svalbard: Observing their distribution, characteristics and evolution Open
Glacier surges are episodes of significantly increased ice flow due to ice-dynamical feedbacks, and are often repeated in a quasi-periodical manner. Ice mass is redistributed during a surge, which leads to surface lowering at high elevatio…

Mismatch between coccolithophore-based estimates of particulate inorganic carbon (PIC) concentration and satellite-derived PIC concentration in the Pacific Southern Ocean Open
Coccolithophores are the main type of calcifying phytoplankton in the Southern Ocean (SO) and are key organisms in the production of particulate inorganic carbon (PIC). However, in situ studies of coccolithophores and in particular of thei…

Landsystem models from remote and field based geomorphological mapping reveal diverse glacier dynamics on Svalbard Open
Glacial landsystems are geomorphological records produced by glaciers that provide important insights into past and present glacier dynamics. Here, we present a snapshot of the diversity in glacier landsystems in Svalbard. We present remot…

Restricted cirque glaciers in the Wicklow Mountains, Ireland, during the Nahanagan Stadial (Greenland Stadial‐1/Younger Dryas) Open
In Ireland, the Nahanagan Stadial (NS) was characterised by cirque glacier, plateau icefield and mountain ice cap expansion and is named after the cirque glacier type‐site of Lough Nahanagan in the Wicklow Mountains. This period is broadly…

Dynamic LIA advances hastened the demise of small valley glaciers in central Svalbard Open
Most small land-terminating glaciers in Svalbard have experienced large recession since the Little Ice Age (LIA) and today are thin, cold, and largely inactive. This likely contrasts to their LIA conditions, but the observational record fr…

Multiple phases of ice-dammed lake formation and drainage associated with a surge of Shisper Glacier, western Karakoram Open
Glacier surges can create ice-dammed lakes when the advancing terminus blocks drainage. Such lakes are inherently unstable and can drain abruptly as glacial lake outburst floods (GLOFs), presenting a hazard to downstream populations and in…

Investigating the signature of a tidewater glacier surge behaviour using geomorphological, sedimentological and geotechnical data: Borebreen, Svalbard.  Open
The sedimentary processes taking place beneath contemporary surging glaciers are difficult to observe directly, yet they are crucial for building a holistic understanding of glacier surge processes and mechanisms. Settings where the sedime…

The role of topography in landform development at an active temperate glacier in Arctic Norway Open
Topography exerts a strong control on how glaciers respond to changes in climate. Increased understanding of this role is important for both refining model predictions of future rates of glacier recession and for reconstructing climatic ch…
