PALSEA2 Meeting in Scotland

Suilven

Tucked away at the Glencanisp Lodge (Lochinver, Scotland) at the base of the Suilven mountain, the recent PALSEA2 meeting focused on databases of sea-level indicators. The meeting brought together experts from the ‘data’ and ‘modelling’ communities. iGlass was well represented (the meeting was organised by iGlass members Natasha Barlow and Anthony Long) with presentations from André Dϋsterhus, Peter Clark, Roland Gehrels, Fiona Hibbert, Glenn Milne, Matt Whipple and Felicity Williams.

Two field days introduced us to the geology and glacial history of the area, as well as examples of salt marsh and isolation basin records of past sea level change. Two days of presentations brought together the latest work on sea-level change and ice sheet interactions with a focus on sea level database creation and their application. Discussions enabled participants to gain insights into the work of others: for some it was their first close encounter with glacial till or salt marsh records in the field, for others it provided useful primer on U-series and cosmogenic dating, as well as insights into data-model integration/comparison.

The relaxed setting allowed senior and junior scientists to interact within a friendly environment and enjoy the stunning Scottish scenery (posters outside, in Scotland, in September!).

iGlass at the EGU 2014

The iGlass consortium was well represented at this years EGU conference in Vienna. Highlights included the co-organised session (CL5.11) “Sea level in interglacials and the last deglaciation” which included the “Milutin Milankovic Medal Lecture” given by Maureen Raymo. It thematised her career with a special focus on her work on the climate variability over the past four million years.

iGlass members gave talks on their current work: Roland Gehrels spoke on the variability of sea-level in the north atlantic during the last millennium; André Düsterhus on the uncertainties of sea-level during the last interglacial and; Fiona Hibbert on a global repository of coral and speleotherm records for past sea level change.

iGlass was also well represented at the poster sessions: Emelie Capron presented a high latitude temperature evaluation across the last interglacial (see current blog), Katy Pol summarised climate in older interglacials (MIS 7,9 and 11); Joy Singarayer presented insights into the modelling of the thermometric contribution to global and regional sea-level rise during the last interglacial; Margot Saher looked at the modes of interglacial sea-level change; Karine Wainer showcased new constraints for MIS 5 and 7 for the Bermuda sea level and; Felicity Williams presented two posters on the use of isostatic scenarios to access coherence between continuous and instantaneous sea level indicators during the last interglacial.

Furthermore, many more contributions of iGlass members were presented in other sessions during the conference week. All in all the conference was seen as a good showcase for our work, which showed the broad range and depth of this project to a wider scientific community!

CL5.11: Sea level in interglacials as a constraint on future changes

iGlass will be running a session at EGU2014. We would like to strongly encourage you to submit an abstract to our session (deadline for abstract submission: 16th January 2014)

Session details: Sea level appears to have been at a higher level than today in at least some of the recent interglacial periods. In this session, we aim to understand how the respective climate histories led to those higher sea levels, and assess how this information can help us constrain projections for future sea level over a range of timescales. Contributions will be welcome that:

  • derive sea level in any of the Quaternary interglacials, either at a single site or across the globe
  • describe or model the (polar) climates that led to higher sea levels
  • model interglacial ice sheet histories, or the respective sea levels
  • link past sea levels with future projections

The session will include work from the UK project iGLASS, but other contributions addressing the above questions will be equally welcome.

Convenors: Eric Wolff, Fiona Hibbert and Dan Lunt

PSMSL 80th Anniversary Workshop

The Permanent Service for Mean Sea Level’s (PSMSL), an important facility responsible for the collection, publication, analysis and interpretation of sea level data from the global network of tide gauges, are holding a workshop on the 28th to 29th Oct 2013 to celebrate their 80th anniversary. Several members of the iGlass team will be attending and presenting at that workshop.

See the following link for details – http://www.psmsl.org/about_us/news/2013/workshop_2013/
