PAST GATEWAYS - Third International Conference and Workshop

May 18 – 22 2015, Potsdam, Germany

PAST Gateways (Past Spatial and Temporal Gateways) is a network with the overall goal to understand and reconstruct Arctic environmental changes, focusing on the period preceding instrumental records and from decadal to millennial timescales. It is six-­‐year program aiming to understand the nature and significance of Arctic spatial and temporal gateways, with special interest on the transitions between major Late Cenozoic climate events such as interglacial to full glacial and full glacial to deglacial states, as well as more recent Holocene fluctuations. Scientists from Europe, Russia, Canada and the USA are involved in this program and they meet every year in a multidisciplinary International Meeting to discuss new research results and improvements in the understanding of Arctic environmental change. I attended the third meeting of the Past Gateways program, its main topics were a) Growth and decay of Arctic Ice Sheets, b) Arctic sea-­‐ice and ocean changes, c) non-­‐glaciated Arctic environments including permafrost change and d) Holocene Arctic environmental changes. I presented a poster with the title ‘Mid to Late Holocene evolution of sea-­‐ice distribution and primary production on the East Greenland Shelf and the NE Fram Strait’ showing preliminary results of my PhD project. It was included in the ‘Poster Session 1’. During this poster session as well as over the whole period of the conference many scientists were interested in my poster and the results shown there.
By those discussions and talks at my poster I gained new perspectives and ideas for further interpretations and work. Especially the Keynote Lecture of Marit-­‐Solveig Seidenkrantz ‘Variability of late Holocene ocean and atmosphere circulation in the Labrador Sea and North Atlantic region – or why that which does not fit, fits extra well” and the talk of Martin Miles ‘Modulations in sea ice in the East Greenland Current during the past two millennia’ gave me new perspectives on the time period and the area I am working on. Overall the conference gave me new insights in methods in polar research, e.g. ice-­‐wedges as climate records, and a better understanding for the processes influencing the Arctic Ocean. Attending the Past Gateways conference was a big benefit for my PhD, I got new ideas and motivation for my work and met scientists working in the same field as I do. The biggest advantage for me was that I could sit down with scientist working on the same material as I do but using different proxy methods. We compared and discussed our data, which gave me a whole new view on my results. I would like to thank ArcTrain for the financial support, which allowed me to attend the third Past Gateways meeting in Potsdam.
