How wet? Hydroclimate reconstruction of the past 7500 years in northern Carpathians, Romania # Journal_Name: Palaeogeography, Palaeoclimatology, Palaeoecology # Volume: 482 # Edition: # Issue: # Pages: 1-12 # Report: # DOI: 10.1016/j.palaeo.2017.05.007 # Online_Resource: # Full_Citation: # Abstract: As natural and anthropogenic ecosystems are dependent on the local water availability, understanding past changes in hydroclimate represents a priority in research concerning past climate variability. Here, we used testate amoebae (TA) and chironomid analysis on a radiocarbon dated complex of small pond and peat bog sediment profiles from an ombrotrophic bog (Tăul Muced, northern Carpathians, Romania) to quantitatively determine major hydrological changes and July air temperature over the last 7500 years. Wet mire surface conditions with a pH between 2.3 and 4.5 were inferred for the periods 4500–2700 and 1300–400 cal yr BP by the occurrence of Archerella flavum, Amphitrema wrightianum and Hyalosphenia papilio. Dry phases in mire surface conditions and a pH between 2.5 and 5 were inferred for 7550–4500, 2750–1300 and 0 cal yr BP–present by the dominance of Nebela militaris, Difflugia pulex and Phryganella acropodia. The quantitative reconstruction of mean July temperature based on the chironomid communities suggests low summer temperatures for the periods 6550–5600, 4500–3150 and 1550–600 cal yr BP, while periods of slightly higher summer temperatures were observed for 5600–4500, 3150–1550 and 100 cal yr BP–present. There is a generally good agreement between drier phases of the peat surface conditions with higher July temperature, suggesting that temperature may have been a controlling factor for water table fluctuation. Our quantitative reconstructions, among the first for central eastern Europe, show a relatively good agreement with other palaeohydrological studies from central eastern Europe, but contrast with others estimates from north-west Europe. Another important aspect of our study is that it provides valuable information on changes in local hydrology and the potential effect of the mean summer temperature over these changes. #------------------ # Publication # Authors: Kaufman, D., N.

We present a global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved at sub-millennial scale (median spacing of 400 years or finer) and have at least one age control point every 3000 years, with cut-off values slackened in data-sparse regions. The data derive from lake sediment (51%), marine sediment (31%), peat (11%), glacier ice (3%), and other natural archives. The database contains 1319 records, including 157 from the Southern Hemisphere. The multi-proxy database comprises paleotemperature time series based on ecological assemblages, as well as biophysical and geochemical indicators that reflect mean annual or seasonal temperatures, as encoded in the database. This database can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, and is publicly available in Linked Paleo Data (LiPD) format. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: Taul Muced # Location: Europe>Eastern Europe>Romania # Country: Romania # Northernmost_Latitude: 47.5739 # Southernmost_Latitude: 47.5739 # Easternmost_Longitude: 24.545 # Westernmost_Longitude: 24.545 # Elevation: 1360 #------------------ # Data_Collection # Collection_Name: TaulMuced.Diaconu.2017 # Earliest_Year: 6625.0 # Most_Recent_Year: -60.0 # Time_Unit: cal yr BP # Core_Length: # Notes: #------------------ # Species # Species_Name: # Species_Code: # Common_Name: #------------------ # Chronology_Information # Chronology: # OriginalDateID depth_top depth_bottom age_type age uncertainty_old uncertainty_young IncludeYN AdditionalNotes # nan 0.0 0.0 Core top -65.0 nan nan Y nan # UBA-26358 19.0 20.0 age14C -30.0 0.0 -60.0 Y Piecea abieas needles # UBA-26357 36.0 37.0 age14C 1220.0 1252.0 1188.0 Y Piecea abieas needles # UBA-25564 52.0 53.0 age14C 1255.0 1285.0 1225.0 Y Piecea abieas needles # UBA-26356 90.0 91.0 age14C 1677.0 1704.0 1650.0 Y Piecea abieas needles # nan 129.0 130.0 Pollen stratigraphic marker 2612.0 nan nan Y Pollen inferred age # nan 139.0 140.0 Pollen stratigraphic marker 2875.0 nan nan Y Pollen inferred age # UBA-26355 154.0 155.0 age14C 4008.0 4039.0 3977.0 N Outlier, Piecea abieas needles # UBA-26354 198.0 199.0 age14C 3985.0 4018.0 3952.0 Y Piecea abieas needles # nan 199.0 200.0 Pollen stratigraphic marker 4481.0 nan nan Y Pollen inferred age # nan 209.0 210.0 Pollen stratigraphic marker 4689.0 nan nan Y Pollen inferred age # nan 224.0 225.0 Pollen stratigraphic marker 5511.0 nan nan Y Pollen inferred age # UBA-24393 243.0 244.0 age14C 5774.0 5807.0 5741.0 Y Piecea abieas needles #------------------ # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ## depth depth,,,centimeter,,insect;paleolimnology;climate reconstructions,,,N,Between 20-39 cm: a gap in the sedimentary profile ## age age,,,calendar year before present,,insect;paleolimnology;climate reconstructions,,,N, ## temperature surface air temperature,midge assemblage,,degree Celsius,Jul,insect;paleolimnology;climate reconstructions,,,N,Norway-Swiss calibration dataset (Heiri et al. 2011);
