Here, we show the suitability of chrysophyte cysts from lake sediments for revealing continental climate variability when used in sensitive sites, such as those in high mountains. We demonstrate that altitude is a main factor influencing the present distribution of chrysophytes and develop a transfer function to evaluate the local “altitude anomaly” on a lake site throughout time. Based on our knowledge of chrysophyte ecology, the altitude anomalies are interpreted as winter/spring climate signatures. The method was applied to a Holocene record from a lake in the Pyrenees showing submillennial climatic variability in this northwestern Mediterranean zone. A warming trend was present from the early Holocene to 4 kyear BP. Comparison with pollen-based reconstructions of summer temperatures denoted a contrasting decrease in continentality between the two parts of the Holocene. Oscillations of 1 cycle per ca. 2,000 years appeared throughout the record. The warmest Holocene winters were recorded during the Medieval Warm Period at ca. AD 900 and 450 and the Roman Warm Period (2.7–2.4 kyear BP). Winters in the period AD 1,050–1,175 were inferred to be as cold as in the Little Ice Age. The period between 3 and 7 kyear BP showed lower intensity in the fluctuations than in early and late Holocene. The cold event, 8,200 years ago, appeared embedded in a warm fluctuation. Another cold fluctuation was recorded around 9 kyear BP, which is in agreement with Irish and Greenland records. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: Lake Redon # Location: Spain # Country: # Northernmost_Latitude: 42.6425 # Southernmost_Latitude: 42.6425 # Easternmost_Longitude: 0.770278 # Westernmost_Longitude: 0.770278 # Elevation: 2240 #------------------ # Data_Collection # Collection_Name: Lake Redon Temp Pla2004 # Earliest_Year: 578 # Most_Recent_Year: 1994 # Time_Unit: years CE # Core_Length: # Notes: #------------------ # Species # Species_Name: # Species_Code: # Common_Name: #------------------ # Chronology_Section # Chronology: #------------------ # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components ( 10 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data, additional_information) # ## year_CE age, ,,years CE, , lake sediment, ,,N, ## temp_chrys_anom_err temperature anomaly, Chrysophyte cysts from lake sediment,error estimate ,degrees Celsius,,reconstruction,,modern analog,N,winter/spring ## sampleID sample name,, , ,, paleolimnology, ,,N, ## temp_chrys_anom temperature anomaly, Chrysophyte cysts from lake sediment, ,degrees Celsius,,reconstruction,,modern analog,N,winter/spring ## age_calyrBP age, ,,calendar years before present, , , ,,N, # #------------------ # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header) # Missing_Values: nan # year_CE temp_chrys_anom_err sampleID temp_chrys_anom age_calyrBP 1994.0 0.13984 RCA003 0.0 -44.0 1984.0 0.15345 RCA006 0.09114 -34.0 1963.0 0.16085 RCA009 -0.19458 -13.0 1943.0 0.13493 RCA012 0.07387 7.0 1932.0 0.14066 RCA015 -0.42006 18.0 1916.0 0.1819 RCA018 -0.47293 34.0 1905.0 0.18423 RCA021 -0.45136 45.0 1900.0 0.15445 RCA024 -0.26746 50.0 1865.83 0.18184 RCA027 0.0267 84.17 1831.67 0.19046 RCA030 -0.00911 118.33 1797.5 0.16562 RCA033 -0.19458 152.5 1763.33 0.19874 RCA036 -0.5804 186.67 1729.17 0.19907 RCA039 -0.27541 220.83 1695.0 0.20688 RCA042 -0.33944 255.0 1660.83 0.19101 RCA045 -0.27641 289.17 1626.67 0.17213 RCA048 -0.45272 323.33 1592.5 0.24079 RCA051 -0.45298 357.5 1558.33 0.27158 RCA054 -0.50968 391.67 1524.17 0.24619 RCA057 -0.68694 425.83 1490.0 0.19974 RCA060 -0.4556 460.0 1469.69 0.22486 RCA063 -0.2817 480.31 1449.38 0.22744 RCA066 -0.21809 500.62 1429.08 0.1979 RCA069 -0.26096 520.92 1408.77 0.20947 RCA072 -0.54926 541.23 1388.46 0.22262 RCA075 -0.77216 561.54 1368.15 0.16585 RCA078 0.09831 581.85 1347.85 0.29124 RCA081 -0.95083 602.15 1327.54 0.28051 RCA084 -0.93508 622.46 1307.23 0.24342 RCA087 -0.7696 642.77 1270.0 0.1833 RCA095 -0.32813 680.0 1221.9 0.23393 RCA098 -0.39037 728.1 1195.66 0.20011 RCA101 -0.41943 754.34 1169.42 0.21139 RCA104 -0.83928 780.58 1143.19 0.22452 RCA107 -0.94759 806.81 1116.95 0.23743 RCA110 -0.91592 833.05 1090.71 0.21781 RCA113 -0.6049 859.29 1064.47 0.22399 RCA116 -0.6749 885.53 1038.24 0.20541 RCA119 -1.039 911.76 1012.0 0.24183 RCA122 -0.40425 938.0 986.96 0.29303 RCA125 -0.35499 963.04 961.92 0.24199 RCA127 0.07779 988.08 945.23 0.27258 RCA130 -0.45796 1004.77 920.19 0.24157 RCA133 0.22066 1029.81 895.15 0.25225 RCA136 0.27102 1054.85 870.12 0.24656 RCA139 -0.31133 1079.88 845.08 0.22384 RCA142 0.00152 1104.92 820.04 0.24564 RCA145 -0.13428 1129.96 795.0 0.29127 RCA148 -0.44895 1155.0 769.96 0.26315 RCA151 -0.14962 1180.04 744.92 0.2888 RCA154 -0.08622 1205.08 719.88 0.31265 RCA157 0.00586 1230.12 694.85 0.28571 RCA160 -0.24945 1255.15 669.81 0.27932 RCA163 -0.13836 1280.19 619.73 0.25176 RCA168 0.22804 1330.27 603.04 0.30376 RCA171 -0.21474 1346.96 578.0 0.35641 RCA174 -0.05361 1372.0
