    Description: This dataset provides the raw pollen counts for the late-glacial sediment sequence retrieved from Lake Haemelsee (Germany) in 2013. The counts are presented against both depth (cm core depth) and time (cal. yr BP) and cover the time interval from ca 15.200 to 10.400 cal yr BP. A total of 106 samples were counted, with higher sampling resolution around the onset and end of the Younger Dryas, and lower sampling resolution elsewhere in the core. The pollen record provides information about both regional vegetation change as well as changes in the within-lake flora. It was produced to inform on the exact age and duration of major palynological transitions during the late-glacial Cores were retrieved from the lake using a 3-m long UWITEC piston corer deployed from a floating coring platform during field work in July 2013. Volumetric samples were obtained from splits of the core and processed in the laboratory (University of Amsterdam, the Netherlands) using standard protocols.

    Description: This dataset provides chironomid counts for the Holocene sediment sequence retrieved from Lake Flocktjärn (Sweden) in 2014. The counts are presented against both depth (m) and age (ka BP). A total of 44 samples were counted. The chironomid counts provide information about changes in the invertebrate fauna of the lake. Cores were retrieved from the lake using a 1-m long handheld piston corer deployed from a floating coring platform during field work in May 2014. Volumetric samples were obtained from splits of the core and processed in the laboratory (University of Amsterdam, the Netherlands) using standard protocols.

    Description: This dataset provides chironomid counts for the Holocene sediment sequence retrieved from Crooked Pond (United States). Sediment cores were retrieved from the lake using a 1-m long handheld piston corer deployed from a floating coring platform during field work in May 2009. Volumetric samples were obtained from splits of the core and processed in the laboratory (University of New Brunswick, Canada) using standard protocols. Chironomid counts are presented against both depth (cm) and age (cal yr. BP). A total of 58 downcore 1-cm-thick samples were analysed, ranging between 477.5cm depth (9056 cal yr BP) and 0.5cm depth (the present). The chironomid record provides information about changes in the chironomid fauna as well as in within-lake conditions. The dataset was produced to inform on the exact age and duration of a major lake-level lowstand during the mid-Holocene. This lowstand was compared to palynological transitions determined on pollen samples from an older core sequence derived from the same coring location.

    Description: This dataset provides counts of chironomid taxa identified in a set of surface sediment samples taken in the region around the town of Kaamanen (Finland). A total of 33 lakes were sampled during field work in August 2006. For each lake, a short sediment core was retrieved from a rubber dinghy using a gravity corer (HON/Kajak corer) with a 62mm diameter. Volumetric samples taken from the 0-1cm sediment depth sample were subsequently processed in the laboratory (Vrije Universiteit Amsterdam, the Netherlands) using standard protocols – this involved 20min treatment with warm KOH (10%) and sieving over a 100um mesh. Chironomid head capsules were subsequently handpicked from the residue, mounted on permanent microscope slides, and identified using the literature. This dataset provides chironomid counts per sample as well as longitude, latitude, elevation and measurements of water depth for each of the samples. Engels et al. (2008) provide additional environmental observations (water temperature, conductivity, pH and O2 profiles) for each of the lakes sampled, as well as water chemistry data. The lakes were either situated on the floodplain of the Muddusjoki river and prone to annual flooding, or they were situated at higher elevations and were isolated from fluvial activity. The chironomid dataset was used to determine the effects of regular inundations on the composition of the chironomid fauna of shallow lakes, as well as to determine the effects on chironomid-inferred July air temperature estimates.

    Description: This dataset provides the percentage-abundances of chironomid taxa identified in a set of surface sediment samples taken in the Plymouth area (Massachusetts, United States) in 2009. For each sample, a short sediment core was retrieved from a rubber dinghy using a gravity corer (both the Glew and the mini-Glew models were used) during field work in June and September 2009. Volumetric samples taken from the 0-1cm sediment depth sample were subsequently processed in the laboratory (University of New Brunswick, Canada) using standard protocols. The procedure involved placing the sample aliquot in a glass beaker and submerging it in warm 10% KOH for ca. 20 mins. Subsequently the material was rinsed over a 100µm mesh and individual head capsules were hand-sorted from the residue and mounted on microscope slides. Chironomid head capsules were identified using Brooks et al. 2007 and encountered taxa that were not present in that handbook are illustrated and described in Engels & Cwynar (2011). This dataset provides chironomid abundances (expressed as percentage of the total chironomid sum) as well as measurements of water depth for each of the samples; Engels & Cwynar (2011) provide additional environmental observations for each of the 8 lakes sampled. A total of 132 surface sediment samples were originally counted, but as 3 samples only reached total chironomid count sums of less-than-50 these were removed from the original dataset, resulting in a final dataset consisting of 129 samples. The chironomid data provides information on within-lake distribution patterns of chironomid taxa for each of the 8 lakes sampled. The dataset was used to determine depth-preferences of each of the taxa encountered, and to determine common threshold depths (i.e. those water depths where abrupt changes in the composition of the chironomid fauna take place). These data were subsequently used to produce site-specific (i.e. one lake) and regional (i.e. 7- or 8-lake) chironomid-water depth inference models.

    Description: This dataset provides chironomid percent-abundance data for an Early Weichselian sediment sequence retrieved from the Nochten mine (Niederlausitz area, Germany) in 2004. Percent-abundances of individual chironomid taxa are presented against relative core depth (m). The lake deposit was encountered in an exposure of Weichselian sediments and was sampled using a box core. The material was dated to the Early Weichselian (ca 80ka BP) using a combination of OSL and 14C dating. A total of 13 samples were analysed for their chironomid content. Samples were taken from the box core, weighted, and subsequently processed in the laboratory (Vrije Universiteit Amsterdam, the Netherlands) using standard protocols – this involved 20min treatment with warm KOH (10%) and sieving over a 100µm mesh. Chironomid head capsules were subsequently handpicked from the residue, mounted on permanent microscope slides, and identified using the literature. This dataset provides chironomid percent-abundances relative to the total count of chironomid head capsules per sample. The chironomid dataset provides insight in the natural evolution of the lake ecosystem and was used to produce a chironomid-inferred July air temperature record.

    Description: This dataset provides chironomid abundance data for a Mid Weichselian sediment sequence retrieved from the Reichwalde mine situated in the Niederlausitz area (Germany) in 1999. Percent-abundances of individual chironomid taxa are presented against relative core depth (m). The lake deposit was encountered in an exposure of Weichselian sediments and was sampled using a box core. The material was dated to the early Mid Weichselian (ca 50ka BP) using 14C dating. A total of 18 samples were analysed for their chironomid content. Samples were taken from the box core, weighted, and subsequently processed in the laboratory (Vrije Universiteit Amsterdam, the Netherlands) using standard protocols - this involved 20min treatment with warm KOH (10%) and sieving over a 100µm mesh. Chironomid head capsules were subsequently handpicked from the residue, mounted on permanent microscope slides, and identified using the literature.
