“…The absence of any isotopic enrichment prior to ca. 7000 BC is tentatively explained by Hammarlund et al (2003) as a consequence from the proximity of the study site to the Preboreal sea during early Holocene. The coastal setting probably decreased the regional groundwater gradient, which may have impeded any lake-level lowering and reduction of lake volume.…”

“…A marked decrease to very low charcoal-inferred fire activity at ca. 4700 BC at Stavsåkra was compared to a short period of lower values in δ 18 O and δ 13 C at Lake Igelsjön (Hammarlund et al, 2003), and ascribed to a brief period of increased precipitation and lowered summer temperature (Greisman and Gaillard, 2009). There is also a period of lower fire activity between 5000 and 4500 BC at Storasjö, but it belongs to a series of time intervals with low fire activity starting before 5000 BP and continuing until 2000 BC.…”

“…5A-C). As in Greisman and Gaillard (2009), we use the compilation of climate proxy records of Hammarlund et al (2003), complemented here by the pollen-inferred temperature curve from Lake Flarken (Seppä et al, 2005) (Fig. 5A).…”

“…Therefore, correlation between low fire activity and short episodes of climate cooling should be further tested. Hammarlund et al (2003) proposed that a rise in groundwater due to an increase in precipitation occurred relatively rapidly, within a few 100 years, shortly after 2050 BC, and argued that a critical climatic threshold for the Northern Hemisphere was passed around 2000 BC. The abrupt decrease in fire activity after 2000 BC at Storasjö, and the low activity until ca.…”

Quantitative reconstruction of Holocene sea ice and sea surface temperature off West Greenland from the first regional diatom data set

et al. 2017

Holocene oceanographic conditions in Disko Bay, West Greenland, were reconstructed from high‐resolution diatom records derived from two marine sediment cores. A modern data set composed of 35 dated surface sediment samples collected along the West Greenland coast accompanied by remote sensing data was used to develop a diatom transfer function to reconstruct April sea ice concentration (SIC) supported by July sea surface temperature (SST) in the area. Our quantitative reconstruction shows that oceanographic changes recorded throughout the last ~11,000 years reflect seasonal interplay between spring (April SIC) and summer (July SST) conditions. Our records show clear correlation with climate patterns identified from ice core data from GISP2 and Agassiz‐Renland for the early to middle Holocene. The early Holocene deglaciation of western Greenland Ice Sheet was characterized in Disko Bay by initial strong centennial‐scale fluctuations in April SIC with amplitude of over 40%, followed by high April SIC and July SST. These conditions correspond to a general warming of the climate in the Northern Hemisphere. A decrease in April SIC and July SST was recorded during the Holocene Thermal Optimum reflecting more stable spring‐summer conditions in Disko Bay. During the late Holocene, high April SIC characterized the Medieval Climate Anomaly, while high July SST prevailed during the Little Ice Age, supporting previously identified antiphase relationship between surface waters in West Greenland and climate in NW Europe. This antiphase pattern might reflect seasonal variations in regional oceanographic conditions and large‐scale fluctuations within the North Atlantic Oscillation and Atlantic Meridional Overturning Circulation.

This contribution examines the climate variations reflected by a mainly lacustrine succession spanning from 17.73 to 14.0 Ma in north‐east Iberia, thus encompassing the Miocene Climatic Optimum (MCO). The study is based on the δ13C and δ18O composition of an array of carbonate facies and marl samples, complemented with sedimentological analysis, illite crystallinity index and magnetic susceptibility data. The onset and ending of the MCO have been detected at ca 17.10‐17.06 Ma and 14.56 Ma, roughly equivalent to the boundaries in the marine record, although with relatively short lags. The variability of the data series evidenced changes in humidity and air temperature through the MCO, some of which coincided with similar variations in other records. Specifically, an evolving positive shift in δ13C values, from 16.5 to 14.5 Ma, seems to fit the Monterey excursion observed in marine records. Likewise, increases in δ18O values between 16.8 and 16.5 Ma and between 14.85 and 14.56 Ma in the study succession concurred with warming intervals recorded in palaeosols of Central Europe, emphasising the coincidence with the temperature maximum at ca 16.6 Ma. A general decline in temperature and an increase in humidity are detected from 14.56 Ma, both with steeper trends until 14.41 Ma then more gradual onwards, indicating the beginning of the Middle Miocene Climatic Transition. These results shed light upon the tightly coincidental features between terrestrial and marine records over those time intervals and, more importantly, highlight the earlier warming and the faster cooling experienced by the lake system as compared with the marine record. These findings provide further evidence to help infer palaeoclimate conditions on a much broader reach than the regional context.
