ice2ice

The Ice2Ice PhD bootcamp 2018 is held in Rosendal, Norway, at the Folgefonn Centre from Monday January 22nd to Friday February 26^th. 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

—————-

“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.).

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).

1. Contributions from both proxy and modeling experts are crucial for a successful workshop.

We hope to see many of you in Copenhagen soon!

Description:

One of the key themes in ice2ice is to what extent past abrupt changes have relevance for future climate change. Inspired by potentially similar warming trends in past (stadial-interstadial and glacial-interglacial) climates and future scenarios, we will discuss the applicability of paleoclimate states as analogues for future warming.

This workshop aims to intercompare proxy data reconstructions, paleoclimate modelling efforts, and future model projections with a particular focus on sea ice related warming in the Arctic (especially Greenland and the Nordic Seas region).

Specific topics during the workshop will be:

• Rate of warming and sea ice loss

Are the rates of warming and sea ice loss in the past, eg. MIS3 stadial-interstadials or the deglaciation (proxy + model), and future scenarios (model) comparable? When we talk of past and current/future change in the Arctic, how good is the analogue in terms of abruptness?

• Nordic Seas vs central Arctic Ocean

Comparison of past sea ice changes in the Nordic Seas (proxy + model) to future changes in the Arctic Ocean (model). If changes in the Nordic Seas during MIS3 should be used as a parallel for potential changes in the Arctic Ocean in a warmer climate (interglacial or future), two questions arise: how do the two oceans compare (e.g. vertical structure) and how would SST/sea ice changes in the two regions affect the atmosphere/Greenland. Specifically, can we use our collective model and proxy data to answer: (1) Is the impact of sea ice loss/SST increase similar for Nordic Seas (MIS3) and Arctic Ocean (interglacial or future), and (2) could the same mechanism lead to abrupt changes?

• Different drivers

When comparing current-to-future climate change with preindustrial-to-last-interglacial changes, or when comparing current-to-future with stadial-to-interstadial changes, we need to consider the different driving mechanisms. Compared to the “apparently unforced” stadial-to-interstadial changes, the two former changes are forced by variations in GHG concentrations and insolation, respectively. To what extent can the different signatures of insolation and GHG changes be disregarded? There are indications that the resulting SST state is dominant for many atmospheric impacts, such that the driver is of less importance, but this needs to be addressed carefully when making past vs future analogues.

Contributions to the above from both the proxy and modeling sides is crucial to a successful outcome of the workshop.
