The Development of a Low Power GNSS System, as Part of a Drone Assisted Environmental Sensor Network for a Glacial Environment

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract We show the development of an innovative Internet of Things Real Time Kinematic Global Navigation Satellite System, to study the short‐term changes in surface velocity of two adjacent Icelandic glaciers, in order to understand the response of glaciers to climate change.

Tracking icebergs with time-lapse photography and sparse optical flow, LeConte Bay, Alaska, 2016–2017 [PDF]

, 2019
We present a workflow to track icebergs in proglacial fjords using oblique time-lapse photos and the Lucas-Kanade optical flow algorithm. We employ the workflow at LeConte Bay, Alaska, where we ran five time-lapse cameras between April 2016 and ...

A Boulder Beach Formed by Waves From a Calving Glacier Revisited: Multidecadal Tsunami–Controlled Coastal Changes in Front of Eqip Sermia, West Greenland

Permafrost and Periglacial Processes
The calving of glaciers regularly produces tsunami‐like waves that pose a serious threat to coastal environments. Those strong waves are not only able to move ice mélange and redistribute icebergs, growlers, or sea ice across a fjord but also flood and ...

Iron and Manganese Cycling in the Atlantifying Barents Sea: Concentrated Inputs and Emerging Limitations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Dissolved iron (dFe) and manganese (dMn) are essential micronutrients required in marine primary production; however, their low availability limits productivity and impacts the efficiency of the biological carbon pump. Therefore, it is crucial to elucidate their sources, sinks, and internal cycling.

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

Brief communication "The 2013 Erebus Glacier tongue calving event" [PDF]

The Cryosphere, 2013
Abstract. The Erebus Glacier Tongue, a~small floating glacier in southern McMurdo Sound, is one of the best-studied ice tongues in Antarctica. Despite this, its calving on the 27 February 2013 (UTC) was around 10 yr earlier than previously predicted. The calving was likely a result of ocean currents and the absence of fast ice.

Multi-method observation and analysis of a tsunami caused by glacier calving

, 2016
. Glacier calving can cause violent tsunami waves which, upon landfall, can cause severe destruction. Here we present data acquired during a calving event from Eqip Sermia, an ocean-terminating glacier in west Greenland.

Episodic Rifting of a Large Igneous Province Concentrated Along a Microcontinent Boundary

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Many large igneous provinces (LIPs) comprise once contiguous magmatic products that are now fragmented across multiple tectonic plates. Emplacement of these voluminous magmatic products is commonly coeval with, or shortly followed by, fragmentation into constituent domains.

Detection of glacier calving events from time-lapse images using computer vision and a neural network

Journal of Glaciology
Ground-based time-lapse cameras are often used to monitor glacier recession, which is primarily driven by the falling of ice from the glacier front, known as iceberg calving or, more commonly, calving events.

The northern sector of the last British ice sheet : maximum extent and demise [PDF]

, 2008
Strongly divided opinion has led to competing, apparently contradictory, views on the timing, extent, flow configuration and decay mechanism of the last British Ice Sheet.
