First ice core records of NO3− stable isotopes from Lomonosovfonna, Svalbard [PDF]

, 2014
Samples from two ice cores drilled at Lomonosovfonna, Svalbard, covering the period 1957–2009, and 1650–1995, respectively, were analyzed for NO3− concentrations, and NO3− stable isotopes (δ15N and δ18O).

Holocene Glacial–Paraglacial–Periglacial Transitions of a Sub‐Arctic Glacial Cirque, Fremri‐Grasárdalur, Northern Iceland

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The aim of this work is to study a variety of glacial, periglacial and paraglacial features found in a small cirque, Fremri‐Grasárdalur, in Tröllaskagi (Northern Iceland). We implement a multidisciplinary approach combining high‐resolution geomorphological mapping, horizontal/vertical boulder displacement (from 1994 to 2019) and surface ...

Seasonal variability of the warm Atlantic Water layer in the vicinity of the Greenland shelf break [PDF]

, 2014
The warmest water reaching the east and west coast of Greenland is found between 200?m and 600?m. Whilst important for melting Greenland's outlet glaciers, limited winter observations of this layer prohibit determination of its seasonality.

Volcanic influence on centennial to millennial Holocene Greenland temperature change

Scientific Reports, 2017
Solar variability has been hypothesized to be a major driver of North Atlantic millennial-scale climate variations through the Holocene along with orbitally induced insolation change.

Harmonising digitised herbarium data to enhance biodiversity knowledge: Major steps towards an updated checklist for the flora of Greenland

PLANTS, PEOPLE, PLANET, EarlyView.
Herbaria worldwide hold centuries of plant data that are key to understanding and protecting biodiversity; however, even with increased digital access, differences in plant naming systems make it difficult to compare records. We developed a semi‐automated workflow that standardises species names and organises herbaria records from multiple institutions

Potential climatic transitions with profound impact on Europe [PDF]

, 2011
We discuss potential transitions of six climatic subsystems with large-scale impact on Europe, sometimes denoted as tipping elements. These are the ice sheets on Greenland and West Antarctica, the Atlantic thermohaline circulation, Arctic sea ice, Alpine

Digitization connects scattered specimens and enables new historical research: Plants from the Lady Franklin Bay Expedition (1881–1884)

PLANTS, PEOPLE, PLANET, EarlyView.
Widespread museum digitization initiatives have made the world's herbaria more accessible than ever, launching a renaissance of specimen use. We highlight the value of digitization to bolster both scientific and historical research using the specimens from the Lady Franklin Bay Expedition (1881–1884) to the Canadian arctic, remembered for its tragedy ...

Pickering Brook Salt Marsh Restoration - Phase II [PDF]

, 2005
In the early 1900’s, the majority of coastal salt marshes in New England were ditched as part of an aggressive mosquito control program. In an attempt to eradicate mosquito-breeding habitat, open water areas were drained by a series of ditches excavated ...

Linking to images and AI‐based identification tools—The only way for Flora projects to survive

PLANTS, PEOPLE, PLANET, EarlyView.
Floras are comprehensive and authoritative catalogues of plants growing in an area of interest. They help people find and name plants, which is achieved by a combination of images, drawings, and text, rarely also maps. Like other catalogues (lexica, dictionaries, telephone books), Floras will not survive unless they move online and become portable ...
