Supplemental Information
STUDY NOTES: Holocene sediment geochemical (C/N, TOC, BSi), physical properties (MS, density), and carbon isotope (d13C) data from 2 lakes on the Vestfirðir Peninsula, Iceland. Composited and normalized BSi and C/N series from the two lakes, plus dead vegetation ages, are also presented.
ABSTRACT SUPPLIED BY ORIGINATOR: Emerging Holocene paleoclimate datasets point to a non-linear response of Icelandic climate against a background of steady orbital cooling. The Vestfirðir peninsula (NW Iceland) is an ideal target for continued climate reconstructions due to the presence of a small ice cap (Drangajökull) and numerous lakes, which provide two independent means to evaluate existing Icelandic climate records and to constrain the forcing mechanisms behind centennial-scale cold anomalies. Here, we present new evidence for Holocene expansions of Drangajökull based on 14C dates from entombed dead vegetation as well as two continuous Holocene lake sediment records. Lake sediments were analyzed for both bulk physical (MS) and biological (%TOC, d13C, C/N, and BSi) parameters. Composite BSi and C/N records from the two lakes yield a sub-centennial qualitative perspective on algal (diatom) productivity and terrestrial landscape stability, respectively. The Vestfirðir lake proxies suggest initiation of the Holocene Thermal Maximum by ~8.8 ka with subsequent and pronounced cooling not apparent until ~3 ka. Synchronous periods of reduced algal productivity and accelerated landscape instability point to cold anomalies centered at ~8.2, 6.6, 4.2, 3.3, 2.3, 1.8, 1, and 0.25 ka. Triggers for cold anomalies are linked to variable combinations of freshwater pulses, low total solar irradiance, explosive and effusive volcanism, and internal modes of climate variability, with cooling likely sustained by ocean/sea-ice feedbacks. The climate evolution reflected by our glacial and organic proxy records corresponds closely to marine records from the North Iceland Shelf.
PurposeRecords of past climate and environment derived from lake sediment records. Parameter keywords describe what was measured in this dataset. Additional summary information can be found in the abstracts of papers listed in the dataset citations.
