The Role of Ice‐Rafted Debris (IRD) on Icebergs' Deterioration

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract During the last ice age, icebergs transported Ice‐Rafted Debris (IRD) more than 3,000 km across the North Atlantic. However, their effect on the deterioration of icebergs and thus where the deposits form is poorly understood. Laboratory experiments and a predictive model (with no fitting parameters) investigating the effects of sediment on ...

Spatial, seasonal and interannual variability of supraglacial ponds in the Langtang Valley of Nepal, 1999–2013

Journal of Glaciology, 2017
Supraglacial ponds play a key role in absorbing atmospheric energy and directing it to the ice of debris-covered glaciers, but the spatial and temporal distribution of these features is not well documented.

Thickness estimation of supraglacial debris above ice cliff exposures using a high-resolution digital surface model derived from terrestrial photography

Journal of Glaciology, 2017
The thickness of supraglacial debris cover controls how it impacts the ablation rate of underlying glacier ice, yet this quantity remains challenging to measure, particularly at glacier scales.

Phosphatase activity and organic phosphorus turnover on a high Arctic glacier [PDF]

Biogeosciences, 2009
Arctic glacier surfaces harbour abundant microbial communities consisting mainly of heterotrophic and photoautotrophic bacteria. The microbes must cope with low concentrations of nutrients and with the fact that both the dissolved and debris-bound ...

In-situ and modelled debris thickness distribution on Panchi Nala Glacier (western Himalaya, India) and its impact on glacier state

Quaternary Science Advances
This study presents extensive in-situ debris thickness measurements over the Panchi Nala Glacier (western Himalaya, India) and models its spatial distribution using remote sensing and ERA-5 reanalysis data.

Ground-penetrating radar measurements of debris thickness on Lirung Glacier, Nepal

Journal of Glaciology, 2017
Supraglacial debris thickness is a key control on the surface energy balance of debris-covered glaciers, yet debris thickness measurements are sparse due to difficulties of data collection.

Debris covered glacier mapping using newly annotated multisource remote sensing data and geo-foundational model

Science of Remote Sensing
The automated mapping of debris covered glaciers remains challenging due to spectral similarity between supraglacial debris (on-glaciers) and periglacial debris (off-glaciers).

Multi‐Year Glaciological and Meteorological Observations on Debris‐Covered Kennicott Glacier, Alaska, 2016–2023

Geoscience Data Journal
Despite increasing availability of satellite‐derived products, in situ glacier observations are pivotal to accurately monitor glacier change and to calibrate and validate glacier models.
