Maker Buoy Variants for Water Level Monitoring and Tracking Drifting Objects in Remote Areas of Greenland

open access: yesSensors, 2020
Meltwater runoff from the Greenland Ice Sheet changes water levels in glacial lakes and can lead to glacial lake outburst flooding (GLOF) events that threaten lives and property.

Chemical species spatial distribution and relationship to elevation and snow accumulation rate over the Greenland Ice Sheet [PDF]

open access: yes, 1996
Major chemical species (Cl−, NO−3, SO2−4, Na+, K+, Mg2+, Ca2+) from 24 snowpits (sampled at a resolution of 3 cm, total 2995 samples) collected from northern, central, and southern Greenland were used for this investigation.

A 200-year 210Pb record from Greenland [PDF]

open access: yes, 1997
A continuous profile of 210Pb activity extending back to 1766 has been developed for a firn/ice core collected at Site D in central Greenland in 1984. Unexpectedly high activities of 210Pb were found at the base of this core (0.032 pCi kg−1 in samples ...

Reconstructions of the 1900–2015 Greenland ice sheet surface mass balance using the regional climate MAR model

open access: yes, 2016
. With the aim of studying the recent Greenland ice sheet (GrIS) surface mass balance (SMB) decrease relative to the last century, we have forced the regional climate MAR (Modele Atmospherique Regional; version 3.5.2) model with the ERA-Interim (ECMWF ...

A new era of sub-millimeter GRB afterglow follow-ups with the Greenland Telescope [PDF]

open access: yes, 2015
A planned rapid submillimeter (submm) Gamma Ray Burst (GRBs) follow-up observations conducted using the Greenland Telescope (GLT) is presented. The GLT is a 12-m submm telescope to be located at the top of the Greenland ice sheet, where the high-altitude and dry weather porvides excellent conditions for observations at submm wavelengths.

Global perspective of nitrate flux in ice cores [PDF]

open access: yes, 1995
The relationships between the concentration and the flux of chemical species (Cl-, NO3 - , SO42-, Na +, K + , NH4 + , Mg 2+ , Ca 2+) versus snow accumulation rate were examined at GISP2 and 20D in Greenland, Mount Logan from the St.

Restricted cirque glaciers in the Wicklow Mountains, Ireland, during the Nahanagan Stadial (Greenland Stadial‐1/Younger Dryas)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT 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 equivalent to the Younger Dryas Stadial and Greenland Stadial‐1 (GS‐1: ~12.9–11.7 ka).

Particulate and water-soluble carbon measured in recent snow at Summit, Greenland [PDF]

open access: yes, 2007
Water-soluble organic carbon (WSOC), waterinsoluble particulate organic carbon (WIOC), and particulate elemental carbon (EC) were measured simultaneously for the first time on the Greenland Ice Sheet in surface snow and in a 3-meter snow pit.

Repeated surging and rapid retreat of a tidewater glacier in Scotland (Younger Dryas/Greenland Stadial 1)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This paper presents evidence of glacier surging in the British landform record. We use new high‐resolution multibeam‐echosounder bathymetry data to map the submarine geomorphology of a former tidewater glacier that drained the Skye Icefield, NW Scotland, during the Younger Dryas Stadial (Greenland Stadial 1) ca. 12.9–11.7 ka.

Early taphonomy of benthic foraminifera in Storfjorden ‘sea‐ice factory’: the agglutinated/calcareous ratio as a proxy for brine persistence

open access: yesBoreas, Volume 52, Issue 1, Page 109-123, January 2023., 2023
The recurrent latent‐heat polynya characterizing Storfjorden (Svalbard, Norway) triggers seasonal formation of thin first‐year sea ice. This leads to the production of dense, salty, and corrosive brines that cascade towards the sea floor and mix with shelf waters. The bottom topography of the fjord is responsible for the retention of these dense waters
