“…The bedrock in the study area was not frozen throughout the advance, and the base of the SIS probably thawed during the Late Weichselian (Jõeleht ; Jirakova et al . ). This idea is supported by studies of Weichselian subglacial landform distribution in Estonia and Latvia, on the Russian Plain (Rattas ; Saks ).…”

A database consisting of radiocarbon ( 14 C), optically stimulated luminescence (OSL), thermoluminescence (TL) and beryllium ( 10 Be) dates was used for timing the advance of the Late Weichselian Scandinavian Ice Sheet (SIS), determining the age of the Last Glacial Maximum (LGM) and the rate of deglaciation. The study area encompasses the southeastern sector of the last SIS between the Baltic Sea and the LGM position in the western part of the East European Plain, covering the Karelian Ice-Stream Complex (ISC) area in the east and the Baltic ISC area in the west. The linear advance and recession rates of the last SIS were estimated to be between 110 and 330 m a -1 and between 50 and 170 m a -1 , respectively. The onset of the last SIS in the Karelian ISC area reached the western shores of Latvia not before 26 OSL ka, and in the Baltic ISC area, on the southern shores of the Gulf of Finland, not before 21 OSL ka. The last SIS reached close to the LGM position earliest in NW Belarus, not earlier than 22.6 cal.

“…Such conditions probably accelerated both the advance and the decay of the last SIS, while continuous permafrost still existed in the north (Jirakova et al . ). The present relief of the study area reflects clearly the topography of the bedrock surface.…”

“…The lowermost plot (panel h) shows that European groundwater ∆δ 18 O late‐Pleistocene values decrease eastward across the continent, consistent with progressive rainout of westerly air masses under warmer (late‐Holocene) versus cooler (late‐Pleistocene) climate conditions (see Figure in Rozanski, ).

“…These “recharge gaps” have been suggested to arise due to changes in precipitation rates in Algeria (Guendouz et al, ), Burkina Faso and Mali (Huneau et al, ), Senegal (Madioune et al, ), Chad, Nigeria, and Egypt (Edmunds, ). In some European areas, recharge gaps have been proposed to occur due to the existence of late‐Pleistocene permafrost (e.g., Jiráková et al, ; Walraevens et al, ) or due to late‐Pleistocene glaciers (Beyerle et al, ). Gaps in 14 C have also been identified in late‐Pleistocene ice wedges that have persisted to present day (Grinter et al, ).…”

Groundwater 18O/16O, 2H/1H, 13C/12C, 3H, and 14C data can help quantify molecular movements and chemical reactions governing groundwater recharge, quality, storage, flow, and discharge. Here, commonly applied approaches to isotopic data analysis are reviewed, involving groundwater recharge seasonality, recharge elevations, groundwater ages, paleoclimate conditions, and groundwater discharge. Reviewed works confirm and quantify long held tenets: (i) that recharge derives disproportionately from wet season and winter precipitation; (ii) that modern groundwaters comprise little global groundwater; (iii) that “fossil” (>12,000‐year‐old) groundwaters dominate global aquifer storage; (iv) that fossil groundwaters capture late‐Pleistocene climate conditions; (v) that surface‐borne contaminants are more common in younger groundwaters; and (vi) that groundwater discharges generate substantial streamflow. Groundwater isotope data are disproportionately common to midlatitudes and sedimentary basins equipped for irrigated agriculture, but less plentiful across high latitudes, hyperarid deserts, and equatorial rainforests. Some of these underexplored aquifer systems may be suitable targets for future field testing.

Groundwater recharged by meteoric water supports human life by providing two billion people with drinking water and by supplying 40% of cropland irrigation. While annual groundwater recharge rates are reported in many studies, fewer studies have explicitly quantified intra-annual (i.e., seasonal) differences in groundwater recharge. Understanding seasonal differences in the fraction of precipitation that recharges aquifers is important for predicting annual recharge groundwater rates under changing seasonal precipitation and evapotranspiration regimes in a warming climate, for accurately interpreting isotopic proxies in paleoclimate records, and for understanding linkages between ecosystem productivity and groundwater recharge. Here we determine seasonal differences in the groundwater recharge ratio, defined here as the ratio of groundwater recharge to precipitation, at 54 globally distributed locations on the basis of 18 O/ 16 O and 2 H/ 1 H ratios in precipitation and groundwater. Our analysis shows that arid and temperate climates have wintertime groundwater recharge ratios that are consistently higher than summertime groundwater recharge ratios, while tropical groundwater recharge ratios are at a maximum during the wet season. The isotope-based recharge ratio seasonality is consistent with monthly outputs from a global hydrological model (PCR-GLOBWB) for most, but not all locations. The pronounced seasonality in groundwater recharge ratios shown in this study signifies that, from the point of view of predicting future groundwater recharge rates, a unit change in winter (temperate and arid regions) or wet season (tropics) precipitation will result in a greater change to the annual groundwater recharge rate than the same unit change to summer or dry season precipitation.
