Abisko, 2003

In the summer of 2003, our first summer in Bergen, Cathy and I took a grand tour of Scandinavia on the way to the Paleolimnology Symposium in Espoo. On the way, we stopped in Abisko, northern Sweden, for a few … Continue reading

The ‘New York’ principle of site selection

If I can make it there, I’ll make it anywhere. It’s up to you, New York, New York. Palaeoecologists typically try to choose sites where the environmental variable they want to reconstruct is likely an important, ideally the most important, … Continue reading

The chironomid triennial

Over at the Subfossil Chironomid group on Facebook, Dr Larocque-Tobler posted a link to Zhang et al. (2017), describing it as impressive. I hadn’t seen the published version of Zhang et al, so I popped over fully prepared to be … Continue reading

Reconstruction number 5

Climate modellers often run their models many times with slightly different initial configurations to get an ensemble of alternate realisations of climate history – parallel universes in silico. What is less well known is that certain proxies, mainly from small … Continue reading

The Lake Silvaplana papers

Intrigued by the slightest of hints of rare mønsters in the Lake Żabińskie chironomid data, I decided to re-read all the papers on the chironomid stratigraphy from the varved Lake Silvaplana, Switzerland, by the same author. These papers, which reconstruct … Continue reading

Air temperature, lake temperature

I’m interested in lake temperatures because I want to go swimming. I’m also interested because some palaeolimnological proxies, for example chironomids, are probably most sensitive to water temperature but are calibrated against and used to reconstruct air temperature. The stronger … Continue reading
