Northern sea ice variability during Dansgaard-Oeschger climate cycles

Changes in sea ice cover in the Nordic Seas likely played a crucial role in amplifying ocean circulation and climate changes of the Dansgaard-Oeschger (D-O) cycles during the last glacial. We investigate the role of sea ice for abrupt Greenland climate changes, using a high-resolution sea ice record from Norwegian Sea core MD99-2284 covering four D-O cycles at 32–40 ka. The sea ice reconstruction is based on abundances of the sea ice diatom biomarker IP25 and the open-water phytoplankton biomarker dinosterol, as well as on semi-quantitative phytoplankton-IP25 (PIP25) sea ice estimates. Our biomarker records indicate that the Norwegian Sea was characterized by a near-perennial sea ice cover during cold stadials and enhanced open-ocean conditions during warmer interstadials. Moreover, we find that initiation of sea ice retreat systematically preceded the onset of major deep-water formation in the Nordic Seas and probably the abrupt D-O warming in Greenland. We thus conclude that the glacial sea ice variability acted as precursor and feedback mechanism for abrupt ocean circulation and Greenland climate change during D-O cycles.

ice2ice PhD bootcamp
Jan 22 – Jan 26 all-day

The Ice2Ice PhD bootcamp 2018 is held in Rosendal, Norway, at the Folgefonn Centre from Monday January 22nd to Friday February 26th. We will stay at the Rosendal Tourist Hotel which is very close by to the centre. We defined four groups who will visit different target audiences on day one like school kids of different age (group 1 and 2), tour companies (group 3) and the local media (group 4). The bootcamp week gives each of the four groups the opportunity to find out what the different audiences would like to know about climate science and then test if we are able to communicate the outcome to the audiences. This test will take place at the Folgefonn Centre. Each audience and locals will be invited to listen to our talks and evaluate our communication skills we hopefully improved during the week with the help of Mathew Reeve and Ellen Viste who will be our mentors.

The group structure is as follows:

Group 1:
Sunniva and Karita

Group 2:
Ida, Anais and Eva

Group 3:
Silje and Jonathan

Group 4:
Lisa and Andreas

The program for the week can be found here (pdf). The program includes a tour through the Folgefonn Centre, the visit of the audiences, presentations by the mentors, group work, evening talks and discussions and a social activity on the Wednesday.

We will get to Rosendal on the Monday by ferry that departures from Bergen Torget at central station 08.50am. The boat ride takes approximately 1.5 hours. The trip back to Bergen on the Friday is also by boat and leaves Rosendal at 06.50am. Ferry tickets for the bootcamp participants have been bought by the organisers and will be handed out upon departure. Please show up at the ferry terminal in time as the next ferry to Rosendal leaves in the late afternoon. As the ferry leaves early Monday morning we ask the Copenhagen-based participants to arrive no later than the day before..

The hostel provides bed linen and towels, but please remember to bring warm clothes and hiking boots as the social activity is taking place outdoors.

We look forward to a productive bootcamp 2018!

Best wishes,
Silje, Ida and Lisa

Martin Miles, Uni Research, Bergen

Ida Margrethe Ringgaard, University of Copenhagen / Danish Meteorological Institute

Lecturers:

Martin Miles, Uni Research, Bergen

—————-

“Statistics is a fascinating subject – unfortunately, its teaching is often excruciatingly dull.”– Foreword in a classic statistics textbook.

The ice2ice statistics workshop aims – in contrast – to be an interesting, illustrative and interactive environment, in which we present and explore the use of statistics and other quantitative methods in climate, paleoclimate, paleoceanography and other geosciences.

We will have a few formal lectures, complemented by lots of informal learning and interactive exchanges between lecturers and participants, and between participants. We will work hands-on in small groups and individually on some example data and our own data sets (paleo proxy, observations and/or model data), trying out different methods on the data sets. We will use “R”, a free and comprehensive software environment for statistical computing and graphics: https://www.r-project.org/

Lectures will cover introductory to advanced concepts and methods, adapted to the interests of the participants. Preliminary topics include:

  • Inferential statistics I and II: Theory and methods of univariate and multivariate statistics, including significance and resampling statistics, e.g., bootstrapping and Monte Carlo simulation methods
  • Time series analysis: time-, frequency- and time-frequency domain (e.g., wavelets)
  • Spatial analysis: geostatistics and more, including spatial autocorrelation and its impacts

The workshop is intended primarily for ice2ice PhD students, and will span 3 or 4 days during week 8 (19-23 February), including a social evening of course. Participation by others from ice2ice is also welcome: Remember you can always learn more statistics!

Please send an email to express your interest: martin.miles@uni.no or iri@dmi.dk. Please include any relevant comments (personal goals for the workshop, special topics of interest, partial attendance, etc.).

Arctic glacier field course, Disko Island
Mar 16 – Mar 26 all-day

The course on Disko Island, western Greenland will offer hands-on research based teaching in the field of ice core science. Introducing participants to key scientific methods critical for understanding past and present climate changes in the Arctic. The field course is interdisciplinary, and will provide training in extracting and analysing ice cores as well as in understanding Arctic climate changes on multiple timescales based on ice cores and ice core proxies. In addition to the empirically based studies, the course will provide an opportunity to study the impact of changes in Arctic climate on glaciers and marginal ice caps on Greenland using a ssimple dynamical glacier model. Through the course, PhDs will learn the theory behind and gain experience with a set of highly relevant field based techniques for extracting climate archives from ice cores. This is currently not covered by traditional graduate programs in Norway.

Partners in the field course include University of Bergen (ice dynamics and paleoclimate), University of Copenhagen (ice core techniques), University of Zurich (dynamical ice modelling), and Scripps Institution of Oceanography (ice-ocean interactions).

Description of activity: During the field course, the participants will be working in groups alternating between learning the theory behind ice coring techniques (snow sampling, snow pits, shallow drilling, deep drilling), ice core proxies (water isotopes, chemical impurities, dating techniques, uncertainties), dynamical modelling of small ice caps (numerical ice flow modelling, SIA, mass balance), dynamics of marine terminating glaciers (ice-ocean interactions, fjord circulation, subglacial discharge, calving laws), as well as hands-on training in the field (including safety when traveling on a glacier). The icecoring will take place on a local ice cap lead by Dorthe Dahl Jensen (NBI), and the lectures and ice modelling activities will take place in Arctic station lead by Kerim H. Nisancioglu (UiB), Andreas Vieli (Zurich) and Fiamma Straneo (Scripps).

Preliminary analysis of the ice core data as well as snow samples obtained (including use of a Piccaro) will be carried out at Arctic station, which is fully equipped with lab spaces and lecture facilities. We will also take advantage of the unique records of climate, fjord hydrography and sea ice conditions from west Greenland available at the station, which is the oldest Arctic research station in the world.

Objectives: Introduce students to field and lab based methods necessary to retrieve key climate data documenting variability of temperature and mass balance of typical Arctic glaciers, as well as to simple dynamical models for understanding the transient response of glaciers and small ice caps to climate changes.

Outcome: Following the course the students will have in-depth insight into ice coring techniques, ice core proxy analysis, a basic understanding of ice dynamics, and hands-on experience with numerical ice flow modelling. The course will also foster a strong international network of PhDs and lecturers in polar climate science.

Responsible: Kerim Hestnes Nisancioglu (GEO/UiB & CEED/UiO) and Dorthe Dahl Jensen (NBI/KU).

Invited lecturers: Andreas Vieli (University of Zurich) and Fiamma Straneo (Scripps/UCSD).

When: 10 days, 16th to 26th of March 2018 (excluding travel to/from Arctic Station).

Where: Arctic Station, Qeqertarsuaq, Disko Island, Greenland

Participants: max 18 PhD students (from Norway, KU and Scripps) merit based.

Costs: 8000NOK/participant to cover accommodation and food at Arctic Station. Travel to
Qeqertarsuaq must be covered by eacth participant (make sure to include travel days)

Credit points: 4 ECTS (lectures, field work, group work, and presentation of results)
