Here we develop and analyze a new lipid biomarker record from Horseshoe Lake (Illinois, USA) to evaluate the climatic conditions associated with hydroclimatic extremes that occurred in this region over the last 1,800 years. We present geochemical proxy evidence of temperature and moisture variability using branched glycerol dialkyl glycerol tetraethers (brGDGTs) and plant leaf wax hydrogen isotopic composition (d2Hwax), and use isotope-enabled coupled model simulations to diagnose the controls on these proxies. Our data show pronounced warming during the Medieval-era (AD 1000-1600) that corresponds to midcontinental mega-droughts. Severe floods on the upper Mississippi River basin also occurred during the Medieval-era, and correspond to periods of enhanced warm-season moisture. Our findings imply that projected increases in temperature and warm-season precipitation could enhance both drought and flood hazards in this economically vital region. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: EAR-1804107 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Oceanic and Atmospheric Administration # Grant: NA18OAR4310427 #--------------------------------------- # Site_Information # Site_Name: Horseshoe Lake HORM12 # Location: Madison County, Illinois # Northernmost_Latitude: 38.704767 # Southernmost_Latitude: 38.704767 # Easternmost_Longitude: -90.081279 # Westernmost_Longitude: -90.081279 # Elevation: 122 #--------------------------------------- # Data_Collection # Collection_Name: HORM12GDGT # First_Year: 240 # Last_Year: 1989 # Time_Unit: AD # Core_Length: 4.29 # Notes: #--------------------------------------- # Chronology_Information # Chronology: # # ID cal_age (yr BP) error depth (cm) thickness (cm) # SURFACE -62 1 0 # 210Pb-1 -54 3 1.5 # 210Pb-2 -13 31 6.5 # 210Pb-3 -2 5 10.5 # 210Pb-3 5 7 15.5 # 210Pb-4 16 10 20.5 # 210Pb-5 31 12 25.5 # 210Pb-6 53 14 30.5 # 210Pb-7 80 31 35.5 # AMBROSIA RISE 150 25 36 # UGAMS-13417 400 25 111.5 1 # UGAMS-13418 980 40 197.5 1 # UGAMS-14454 800 20 225 3 # UGAMS-13419 1220 25 254.5 1 # UGAMS-15039 990 25 256.5 1 # UGAMS-15040 990 25 285.5 1 # UGAMS-15041 1370 25 298.5 1 # DAMS-005563 1316 24 330 1 # UGAMS-13420 3560 30 347.5 1 # UGAMS-14455 1620 25 377.5 1 # UGAMS-14456 1650 20 389.5 1 # #--------------------------------------- # 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_cm depth,,,centimeter,,Climate Reconstructions;Paleolimnology,,,N, ## age_AD age,,,year Common Era,,Climate Reconstructions;Paleolimnology,,,N, ## MBT5Me' methylation index of branched tetraethers,,,dimensionless,,Paleolimnology,,liquid chromatography mass spectrometry,N, ## MAAT air temperature,glycerol dialkyl glycerol tetraether index,,degree Celsius,annual,Climate Reconstructions;Paleolimnology,,regression analysis,N,mean annual air temperature from MBT5Me' #------------------------ # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: depth_cm age_AD MBT5Me' MAAT 5 1989 0.524 15.8 13 1955 0.507 15.2 19 1929 0.493 14.8 29 1885 0.558 16.9 43 1820 0.513 15.4 49 1792 0.522 15.7 54 1769 0.506 15.2 69 1699 0.595 18.1 82 1640 0.516 15.5 88 1613 0.508 15.3 95 1583 0.531 16.0 109 1526 0.587 17.8 120.5 1485 0.508 15.3 128 1457 0.575 17.4 159 1348 0.580 17.6 161 1341 0.576 17.5 179 1268 0.572 17.3 180.5 1259 0.580 17.6 189 1221 0.570 17.3 227 1180 0.557 16.8 229 1169 0.566 17.1 235 1135 0.558 16.9 251.5 1035 0.554 16.8 259 994 0.553 16.7 279 882 0.541 16.3 299 767 0.542 16.4 304.5 737 0.519 15.6 316 689 0.523 15.8 319 677 0.521 15.7 339 600 0.540 16.3 379 441 0.571 17.3 389 401 0.573 17.4 403.5 340 0.542 16.4 405 336 0.545 16.5 407 328 0.550 16.6 429 240 0.543 16.4
