Abstract. Marine-terminating outlet glacier terminus traces, mapped from satellite and aerial imagery, have been used extensively in understanding how glaciers adjust to climate change variability over a range of timescales. Numerous studies digitized termini manually, but this process is labor intensive, no consistent approach exists. A lack coordination leads duplication efforts, particularly for Greenland, which major scientific research focus. At the same time, machine learning...
ABSTRACT The increasingly negative mass balance of the Greenland ice sheet (GrIS) over last ~25 years has been associated with enhanced surface melt and increased loss from marine-terminating outlet glaciers. Accelerated retreat during 2000–2010 was concentrated in southeast northwest sectors sheet; however, there considerable spatial temporal variability timing magnitude both within between these regions. This behaviour yet to be quantified compared for all glaciers Furthermore, it is...
Abstract Frontal ablation from tidewater glaciers is a major component of the total mass loss Greenland ice sheet. It remains unclear, however, how changes in atmospheric and oceanic temperatures translate into frontal ablation, part due to sparse observations at sufficiently high spatial temporal resolution. We present high-frequency time-lapse imagery (photos every 30 min) iceberg calving meltwater plumes Kangiata Nunaata Sermia (KNS), southwest Greenland, during June–October 2017,...
Abstract Helheim Glacier, one of the largest marine‐terminating outlet glaciers draining Greenland Ice Sheet, underwent significant retreat and acceleration in early 2000s, accounting for an appreciable proportion ice sheet's mass loss during that period. Using a range remotely sensed datasets, we show despite subsequent readvance, glacier has continued to lose thin, retreated inland retracted position occupied 2005. Critically, near‐terminus is up 100 m thinner than 2005, front 5 km within...
Knowledge about the hydraulic connections between submarine groundwater discharge (SGD) and its terrestrial coastal catchment is relevant with regard to management of marine waters in karst areas. This study applies different methods monitoring approaches trace SGD Burren Limestone Plateau Galway Bay western Ireland, via an excavated sinkhole shaft deep conduit. Areas potential were first delineated based on sea surface temperature anomalies using Landsat satellite images. Two fluorescent...

<p>Successful prediction of the response Greenland Ice Sheet to climate warming requires accurate estimation future ice loss from tidewater glaciers. Patterns glacier retreat and advance have acted as an important proxy for understanding processes associated with frontal ablation. It has not however been possible effectively constrain commonality in these observed patterns that can then be directly linked influence specific controls on loss. Here, we investigate planform...
