Dear members and friends of RAGMAC,

The IACS Working Group on Regional Assessments of Glacier Mass Change
(RAGMAC, [1]) is launching a "glacier volume change intercomparison
experiment" and invites you to participate in this community effort.

We provide digital elevation models from space-borne sensors (ASTER,
TDX) and ask participants to assess glacier volume changes in different
regions and two types of experiments.

In experiment 1, the task is to estimate glacier volume changes for a
given time period for comparison to air-borne validation data.
Therefore, the focus is on the time problem – try to match the
validation period as best as possible, including seasonal corrections if
necessary.

In experiment 2, the focus of the experiment is on the processing
problem, which means evaluating how the different processing steps (e.g.
co-registration) and corrections (e.g. radar penetration correction)
affect the overall volume change estimates.

We invite you to have a look at the general description of the
experiments in the GoogleDocs [2] as well as at the corresponding tasks
& data webpage [3].

If you are interested in participation, please register for the virtual
kick-off meeting, which will take place end of October:
https://docs.google.com/forms/d/1aa3A5pppy7Di7ibGkl5nhZa7yzzHsTCYKFcmNPf6eM4

We are looking forward to start this community effort with you!

[CRYOLIST] Call for Abstracts: "Arctic Ocean changes and processes" at OSM22 -- Deadline Wed !

Last chance to submit, deadline on Wed !


Dear colleagues,
please consider submitted an Abstract to the OSM22 sessions on Arctic ocean
gateways (HL07) or the one on Arctic Ocean changes and processes (HL10).
Both sessions are planned as hybrid sessions, so both in-person and remote
presentations are welcome.

The Abstract deadline is Sept 29th 2021.
 https://www.aslo.org/osm2022/scientific-sessions/.

HL10 Arctic Ocean changes and processes
The central Arctic Ocean is a deep basin divided by various subsurface
ridges, and bordering on extensive shallow shelf regions and passages
connecting to adjacent seas. Amid large-scale changes in the Arctic sea ice
cover, advective pathways, and regional Pacification and Atlantification,
recent observational campaigns and numerical simulations have highlighted
the importance of the emerging local and regional processes on the changes
in the ocean and sea ice. This includes turbulence and eddies. In recent
years, measurements undertaken by multidisciplinary programs have
increasingly focused on the annual cycle in the Arctic Ocean, by providing a
context for historical in-situ measurements collected mostly in spring and
summer. Further, modelling efforts governed by output from the global
Coupled Modelling Intercomparison Project (CMIP5/6) and from high-resolution
sea ice-ocean regional simulations have led to a more comprehensive
understanding the Arctic oceanic variability on a wide range of temporal and
spatial scales. In this session, we welcome contributions based on recent
campaigns, such as the Multidisciplinary drifting Observatory for the Study
of Arctic Climate (MOSAiC) or those under the umbrella of the Synoptic
Arctic Survey (SAS), as well as on the analysis of the long-term datasets of
key environmental quantities, such as sea ice concentration, sea ice
thickness, freshwater content, macronutrients, carbon and ocean
acidification. Modeling studies using CMIP class models and regional
high-resolution ice-ocean simulations are welcome, as well as studies
combining observations and modeling. We explicitly invite studies of
connections in the Arctic Ocean itself, hemispheric linkages to lower
latitudes, coupled feedback involving sea-ice, snow and the atmosphere, and
interdisciplinary studies addressing biogeochemical processes. We also
welcome outreach efforts from school teachers and students who are
interested in the present and future of the Arctic.

HL07 Arctic ocean gateways - changes, processes, and impacts
The Arctic Ocean connects to the North Atlantic through gateways to the east
(Fram Strait and Barents Sea opening) and west (Barrow, Nares and Davis
Straits) of Greenland, and to the North Pacific through Bering Strait.
Gateway exchanges of heat, freshwater, nutrients and other properties
between the Arctic Ocean and the subpolar seas are expected to respond to
changing climate, with potentially important implications for Arctic Ocean
circulation, sea ice evolution, deep water formation, ocean-ice sheet
interactions and ecosystems. Paleo data also shows that gateway fluxes have
changed in the past, with important climate impacts. Ongoing observational
efforts have focused on quantifying and understanding gateway exchanges.
Model simulations provide further data to assess the gateway fluxes and
their impacts both in the Arctic Ocean and in the North Atlantic. This
session aims to advance understanding of Arctic gateway exchanges, including
their drivers and impacts, by bringing together analysis of past, present,
and future changes. We invite studies that use observations, proxies, and/or
models to analyze the various fluxes through the Arctic gateways and their
downstream impacts. This includes, but is not limited to, studies of heat
and freshwater fluxes, water masses, biogeochemical fluxes, sea ice fluxes,
impacts of gateway fluxes on ocean circulation and biogeochemistry,
presentations of new datasets from the Arctic gateways, and future
observational strategies for the gateways.

Cheers,
Ben, on behalf of the session organizing teams (Alex Jahn, Paul Myers,Craig
Lee, Michael Karcher, Ying-Chih Fang, Yevgeny Aksenov)

[CRYOLIST] OSM22: Session OD15 Analyzing Sea Ice with Machine Learning Techniques (Deadline Sept29)

Dear colleagues,

Apologies for cross posting. We invite you to submit your abstracts to the session OD15 Analyzing Sea Ice with Machine Learning Techniques, at the Ocean Sciences Meeting 2021. A description of the session is below.

Link to abstract submission: https://osm2022.secure-platform.com/a

Description: As climate change accelerates rapidly throughout the world, research has shown that the regions that are the most severely affected are the Arctic and the Antarctic. Therefore, it is especially important to monitor geophysical parameters at the polar regions to assess the impacts of climate change. One such parameter is sea ice drift, which yields insights into the rates of global warming as well as key impacts on oceans and their ecological systems. Furthermore, analyzing the rate of melting sea ice aids in the understanding of climate change; sea ice is also important in reflecting solar energy. Changes in sea ice can disrupt normal ocean circulation. More generally, because sea ice is present in highly dynamic environments that involve winds and ocean currents, it can yield insights about how society can work to implement policies to both mitigate and adapt to climate change. Recently, machine learning methods have emerged as a key asset in assessing sea ice and deriving the insights that come with it. In terms of techniques, these range from simple linear regression to random forest ensemble models (RFs), and from support vector machines (SVMs) to artificial neural networks (ANNs). For example, harnessing convolutional neural networks (CNNs) on multitemporal satellite imagery data can yield results on the rate and severity of ice melt. Parameters to consider include concentration, thickness, drift velocity, and more, with machine learning-ready data collected from buoys, satellites, drones, in addition to feet on the ground. The goal of this session is to foster the interdisciplinary collaborations that are necessary at this exciting intersection. While artificial intelligence is crucial for the future of this area of study, we recognize the unique importance of domain-specific knowledge. Therefore, we seek contributions from both the computer science and cryospheric sciences communities.

The deadline for abstract submission is September 29, 2021.

Very much looking forward to your participation!

Abstract: Climate warming is rapidly transforming Arctic ecosystems and melting the Greenland Ice Sheet (GrIS). Terrestrial records of a GrIS smaller than today and the ecosystems that emerged in formerly ice-free areas are crucial for understanding ice sheet and ecosystem sensitivity to warming, but rare due to present ice cover. Basal materials from ice cores can be a critical archive of past ice-free periods. The Camp Century ice core, collected in 1966 from northwestern Greenland, was the first ice core drilled to the bed of an ice sheet and retrieved 3.5 m of subglacial sediment. However, the subglacial sediment was incompletely studied and then misplaced for decades – until it was rediscovered in 2017. Now, we can apply modern analytical techniques to the sediment that were unimaginable at the time of its collection nearly 60 years ago.

The upper- and lower-most sub-glacial sediment from the Camp Century ice core contains a multi-million-year record of vegetation and glacial history in northwestern Greenland. The sediment preserves lipid biomarkers and frozen plant macrofossils, including arctic willow, twigs, moss leaves and stems, and fungal spores, that resemble tundra vegetation from modern ice-free areas of Greenland. Enriched water stable isotope values from sediment pore ice require precipitation at lower elevations and warmer temperatures that imply ice-sheet absence. Pore ice ion concentrations, scanning electron microscope analyses of grain coatings, and automated quantitative mineralogy analyses indicate the upper and lower sediment have different weathering histories. However, multiple geochronometric techniques (apatite U-Th/He, hornblende 40Ar/39Ar, and zircon, apatite, rutile U-Pb) indicate indistinguishable provenance between both samples, suggesting that the upper-most sediment was reworked from older local surface materials and further weathered. Cosmogenic 26Al/10Be in quartz and infrared stimulated luminescence (IRSL) ages of feldspar constrain the burial of the lower-most sediment between <3.2 ± 0.4 Ma and >0.7 (likely >1.4 Ma). In the upper-most sediment, replicate fading-corrected IRSL measurements of different grain sizes from the same sub-sample indicate that the last exposure to sunlight was 391 ± 28 ka. The IRSL data are consistent with the cosmogenic 26Al/10Be burial age of <1.0 ± 0.1 Ma of the upper sediment, which together mandate <14 kyr of exposure during the last ice-free event.

The subglacial sedimentary record from the Camp Century ice core documents at least two episodes of ice-free, vegetated conditions, each followed by glaciation. The lower sediment derives from an Early Pleistocene GrIS advance and contains the oldest record of Greenland vegetation recovered from beneath the ice sheet. The upper sediment provides direct terrestrial evidence for an ice-free northwestern Greenland within the last 400 kyr, possibly during the Marine Isotope Stage (MIS) 11 interglacial. Ice sheet models that maintain ice-free conditions at Camp Century require a minimum sea-level contribution of 1.6 m, and possibly more, from Greenland. While the GrIS survived most Pleistocene interglacials, much of it melted at least once in the last million years. The loss of the northwestern GrIS and the emergence of a tundra ecosystem during MIS 11 underscores ice-sheet sensitivity to prolonged interglacial warmth.

[CRYOLIST] Two post-docs in arctic microbial ecology in Sweden

Two post-doc in arctic microbial ecology at SLU in Sweden


-------- Forwarded Message --------

Two post-doc positions in Microbial Ecology are available at the Department of forest mycology and plant pathology, Swedish University of Agricultural Sciences in Uppsala, Sweden. The positions are part of a large interdisciplinary project running 2021-2026 (https://kaw.wallenberg.org/en/research/winter-studies-arctic-yield-new-insights-greenhouse-gas-emissions). The project aims to understand and quantify how processes during the arctic winter may be decisive for overall feedbacks from arctic tundra to the global climate. Plant and microbial ecologists work together with specialists in up-scaling based on drone technology and satellite imaging. The project will benefit from ongoing collaborations between plant ecologists (University of Umeå) and fungal and microbial ecologists (SLU, Uppsala). 

 

We are recruiting two postdoctoral colleagues for the microbial ecology aspects of the project. The holder of position 1 will focus on bacterial and archaeal ecology during the winter, more specifically the temporal dynamics of their functional roles, including the functional communities involved in nitrogen cycling. The holder of position 2 will focus on fungal ecology, particularly how different mycorrhizal communities may play contrasting roles during the winter and across vegetation mosaics.
