Between 1800 and 1929, female earth scientists existed in significant numbers: 210 are presented here, including newly discovered hydrogeologist Norah Dowell Stearns. Gender discrimination made access to university difficult and access to scientific careers even harder. They found several ways to overcome these difficulties thanks to the support of their parents or to the more ambiguous support of husbands or academic male mentors, through staying single, and through teamwork with other women.

Glacier retreat elevates the risk of landslides released into proglacial lakes, which can trigger glacial lake outburst floods (GLOFs). This study maps proglacial lake evolution and GLOF hazard scenarios at Fjallsjökull glacier, Iceland. Lake volume increased from 1945–2021 and is estimated to triple over the next century. Three slopes are prone to landslides that may trigger GLOFs. Results will mitigate flood hazard at this popular tourism site and advance GLOF research in Iceland and globally.

We study the Holocene period, which started about 11,700 years ago, through 841 computer simulations to better understand the history of the Greenland Ice Sheet. We accurately match historical surface elevation records, verifying our model. The simulations show that an ice bridge that used to connect the Greenland ice sheet to Canada collapsed around 4,900 years ago and still influences the ice sheet. Over the past 500 years, the Greenland ice sheet has contributed 12 millimeters to sea levels.

Geothermally active regions beneath glaciers not only influence local ice flow as well as the mass balance of glaciers but also control changes of subglacial water reservoirs and possible subsequent glacier lake outburst floods. In Iceland, such outburst floods impose danger to people and infrastructure and are therefore monitored. We present a novel computer-simulation-supported method to estimate the activity of such geothermal areas and to monitor its evolution.

We present a unique insight into the shape and development of a subglacial lake over a 7-year period, using repeated radar survey. The lake collects geothermal meltwater, which is released in semi-regular floods, often referred to as jökulhlaups. The applicability of our survey approach to monitor the water stored in the lake for a better assessment of the potential hazard of jökulhlaups is demonstrated by comparison with independent measurements of released water volume during two jökulhlaups.

Surface albedo quantifies the fraction of the sunlight reflected by the surface of the Earth. During the melt season in the Northern Hemisphere solar energy absorbed by snow- and ice-covered surfaces is mainly controlled by surface albedo. For Icelandic glaciers, air temperature and surface albedo are the dominating factors governing annual variability of glacier surface melt. Satellite data from the MODIS sensor are used to create a data set spanning the glacier melt season.

We project 21st century change and uncertainty in 25 river flow regime metrics (signatures) for a deglaciating river basin. The results show that glacier-fed river flow magnitude, timing and variability are sensitive to climate change and that projection uncertainty stems from incomplete understanding of future climate and glacier-hydrology processes. These findings indicate how impact studies can be better designed to provide more robust projections of river flow regime in glaciated basins.

Short summary
Geophysical systems can often contain scientific parameters whose values are uncertain, complex underlying dynamics, and field measurements with errors. These components are naturally modeled together within what is known as a Bayesian hierarchical model (BHM). This paper constructs such a model for shallow glaciers based on an approximation of the underlying dynamics. The evaluation of this model is aided by the use of exact analytical solutions from the literature.

We apply a framework to compare and objectively accept or reject competing melt and run-off process models. We found no acceptable models. Furthermore, increasing model complexity does not guarantee better predictions. The results highlight model selection uncertainty and the need for rigorous frameworks to identify deficiencies in competing models. The application of this approach in the future will help to better quantify model prediction uncertainty and develop improved process models.

The regional climate model HIRHAM5 is evaluated over Vatnajökull, Iceland, using automatic weather stations and mass balance observations from 1995 to 2014. From this we asses whether the model can be used to reconstruct the mass balance of the glacier. We find that the simulated energy balance is underestimated overall, but it has been improved by using a new albedo scheme. The specific mass balance is reconstructed back to 1980, thus expanding on the observational records of the mass balance.

Sub-meter satellite stereo images (Pléiades and WorldView2) are used to accurately measure snow accumulation and winter mass balance of Drangajökull ice cap. This is done by creating and comparing accurate digital elevation models. A glacier-wide geodetic mass balance of 3.33 ± 0.23 m w.e. is derived between October 2014 and May 2015. This method could be easily transposable to remote glaciated areas where seasonal mass balance measurements (especially winter accumulation) are lacking.

This work includes a study on the effects of dust deposition on the mass balance of Brúarjökull, an outlet glacier of Vatnajökull, Iceland's largest ice cap. A model was used to simulate dust deposition on the glacier, and these periods of dust were compared to albedo measurements at two weather stations on Brúarjökull to evaluate the dust impact. We determine the influence of dust events on the snow albedo and the surface energy balance.

In Earth sciences, pH-driven reactions in porous environments impact natural processes like mineral dissolution and groundwater remediation. Traditional models struggle due to pore-scale complexities. This study explores how porous structure and flow rate affect mixing and chemical reactions. Surprisingly, pH-driven reactions occur faster than predicted, emphasizing water’s unique pH behavior in porous media.

In this paper, we use a novel surface nuclear magnetic resonance (SNMR) method for rapid high-quality data acquisition. The SNMR results from more than 100 soundings in three different case studies were used to map groundwater. The soundings successfully track the water table through the three areas and are compared to boreholes and other geophysical measurements. The study highlights the use of SNMR in hydrological surveys and as a tool for regional mapping of the water table.

The formation of underground cavities, called karsts, resulting from carbonate rock dissolution, is at stake in many environmental and societal issues, notably through risk management and the administration and quality of drinking water resources. Facing natural environment complexity, we propose a laboratory study combining hydro-chemical monitoring, 3D imaging, and non-invasive observation of electrical properties, showing the benefits of geoelectrical monitoring to map karst formation.

Although invisible, groundwater plays an essential role for society as a source of drinking water or for ecosystems but is also facing important challenges in terms of contamination. Characterizing groundwater reservoirs with their spatial heterogeneity and their temporal evolution is therefore crucial for their sustainable management. In this paper, we review some important challenges and recent innovations in imaging and modeling the 4D nature of the hydrogeological systems.

We present a data-driven approach to select optimal locations for groundwater monitoring wells. The applied approach can optimize the number of wells and their location for a network reduction (by ranking wells in order of their information content and reducing redundant) and extension (finding sites with great information gain) or both. It allows us to include a cost function to account for more/less suitable areas for new wells and can help to obtain maximum information content for a budget.

We present results of a hydrologic study of groundwater recharge near the city of Arequipa, Peru. There are a number of springs below a high-elevation salar that show some chemical evidence of connectivity to the salar basin, possibly facilitated by faults in region. These results suggest that this salar basin is not a strictly terminal lake but that some interbasin groundwater flow exists. In addition, a high-elevation forest ecosystem seems important for groundwater recharge as well.

The effect of soluble reduced iron, Fe(II), on fluorescence data (excitation–emission matrix spectra parsed using parallel factor analysis) is difficult to quantitatively assign. We added varying quantities of Fe(II) into groundwater from an anaerobic aquifer. We showed that the overall fluorescence intensity decreased nonlinearly as Fe(II) increased from 1 to 306 mg L-1 but that the parallel factor analysis component distribution was relatively insensitive to Fe(II) concentration.

We measured the silicon isotopic composition of groundwater from Rottnest Island, Western Australia, to investigate water–rock interactions in a coastal aquifer. Silicon isotopic ratios varied spatially across the island and were related to secondary mineral formation and vertical mixing within the aquifer. We find that silicate dissolution occurs in the freshwater–seawater transition zone, supporting the recent recognition of submarine groundwater discharge in the oceanic silicon isotope cycle.

The rapid decline of the Dead Sea level since the 1960s has provoked a dynamic reaction from the coastal groundwater system, with physical and chemical erosion creating subsurface voids and conduits. By combining remote sensing, geophysical methods, and numerical modelling at the Dead Sea’s eastern shore, we link groundwater flow patterns to the formation of surface stream channels, sinkholes and uvalas. Better understanding of this karst system will improve regional hazard assessment.

We evaluate groundwater recharge rates in a semi-arid area that has undergone land-use changes. The widespread presence of old saline groundwater indicates that pre-land-clearing recharge rates were low and present-day recharge rates are still modest. The fluctuations of the water table and tritium activities reflect present-day recharge rates; however, the water table fluctuation estimates are unrealistically high, and this technique may not be suited for estimating recharge in semi-arid areas.

Dissolved organic carbon within groundwater and processes controlling it remain largely unknown. The average groundwater concentration at this coastal site was 5 times higher than the global median, doubling with depth, but with no change in chromatographic character. The lack of oxygen limited the rate of organic matter processing, leading to enhanced preservation. Changes in coastal hydrology could lead to the flux of unreacted organic carbon.

Coastal areas are highly populated and seawater intrusion endangers the already scarce freshwater resources. We use, for the first time, a geophysical experiment called cross-hole electrical resistivity tomography to monitor seawater intrusion dynamics. The technique relies on readings of rock and water electrical conductivity to detect salt in the aquifer. Two years of experiment allowed us to reveal variations in aquifer salinity due to natural seasonality, heavy-rain events and droughts.

End member type was found to significantly affect water distribution as lower flux was observed with ice-wedge degradation. Results suggest ice degradation can influence partitioning of sequestered carbon as carbon dioxide or methane.

We provide evidence of high groundwater storage and flow in catchments with active glaciers. Groundwater is found within gravels at the front of glaciers and replenished by both ice melt and precipitation. We studied a glacier in Iceland for 3 years, characterising the aquifer properties and measuring groundwater, river flow and precipitation. The results are important for accurately measuring meltwater and show that groundwater can provide strategic water supplies in de-glaciating catchments.

Braided rivers are uncommon internationally but are important freshwater resources. However, there is limited understanding of how characteristics unique to braided rivers affect groundwater–surface water flow paths. This article reviews prior studies that have investigated groundwater–surface water interactions in these rivers and their associated aquifers to provide guidance on methodologies most suitable for future work in braided rivers and highlight gaps in current knowledge.

The flow of water is often inferred from water levels and gradients whose measurements are considered trivial despite the many steps and complexity of the instruments involved. We systematically review the four measurement steps required and summarise the systematic errors. To determine the accuracy with which flow can be resolved, we quantify and propagate the random errors. Our results illustrate the limitations of current practice and provide concise recommendations to improve data quality.

Exchange fluxes between groundwater and surface waters can be quantified using temperature measurements from the upper sediment layers of streams and lakes assuming the thermal properties of sediments. This study quantified the natural variabiilty in sediment thermal conductivity in the vertical direction at the bed of surface waters and showed that fluxes can change by up to +/-75 % depending on using standard literature values or in situ measurements for sediment thermal conductivity.

Water resource management on volcanic islands is challenging and faces several issues. Taking advantage of new heliborne geophysical technology, correlated with borehole and spring data, we develop a watershed-scale conceptual model and demonstrate that permeability increases with age for the studied formations. Moreover, complex geological structures lead to preferential flow circulations and to discrepancy between topographical and hydrogeological watersheds, influencing river flow rates.

Managed aquifer recharge allows increasing water resources and can be used to improve water quality. We assess the degradative capabilities of infiltrating pollutants by mapping the composition of microbial communities linked to periods of infiltration/drought. From samples of soil, surface and groundwater, we found some microbial species involved in the nitrogen and carbon cycles. Furthermore, we found that, during infiltration, microbial abundance rises, increasing degradative capabilities.

We investigated the wetland system classified as a threatened ecological community and found that organic-rich soil close to surfaces retains significant moisture necessary for ecosystems. At the base of the swamp an identified sand layer allows relatively rapid drainage and lateral groundwater interaction. Evaporation estimated from stable water isotopes from sediments indicated that groundwater contribution to the swamp is significant in dry periods, supporting ecosystems when water is scarce.

Using the arithmetic averages of precipitation isotope values, Wu et al. (2017) concluded that the Badain Jaran Desert (BJD) groundwater is recharged by modern local meteoric water. However, based on weighted mean precipitation isotope values, our further analysis shows that modern precipitation on the Qilian Mountains is more likely to be the main source of the groundwater and lake water in the BJD, as found. We believe this comment provides an important improvement for their study.

Based on hydrochemical and isotopic analysis, we investigated the potential hydrogeological processes responsible for the increasing groundwater salinity in the coastal aquifer of Yang–Dai River coastal plain, northern China. Seawater intrusion is the major aspect and can be caused by vertical infiltration along the riverbed at the downstream areas, and lateral inflow into fresh aquifer. Geothermal water also makes a significant contribution to increasing the groundwater salinity.

Laboratory experiments using water-filled sand and gravel samples with significant contents of iron oxide coatings were performed to identify the relationship between effective hydraulic radius and nuclear magnetic resonance (NMR) response. Our interpretation approach for the NMR data leads to reliable estimates of hydraulic conductivity without calibration, but is limited to coarse material for physical reasons. An NMR-based observation system for iron clogging in boreholes is planned.

This article tackles the problem of finding the origin of groundwater in basin aquifers adjacent to mountains. In particular, we aim to determine whether the recharge occurs predominantly through stream infiltration along the mountain front or through subsurface flow from the mountain. To this end, we discuss the use of routinely measured variables: hydraulic head, chloride and electrical conductivity. A case study from Australia demonstrates the approach.

This study uses a multi-tracer geochemical approach to determine the extent of artesian groundwater discharge into an economically important alluvial aquifer. We compare estimates for artesian discharge into the alluvial aquifer derived from water balance modelling and geochemical data to show that there is considerable divergence in the results. The implications of this work involve highlighting that geochemical data should be used as a critical component of water budget assessments.

The determination of groundwater age can aid characterization of aquifers, providing information on groundwater mixing, flow, volume, and recharge rates. Here we assess a recently discovered groundwater age tracer, Halon-1301. Its performance as an age tracer is assessed against six other well-established, widely used age tracers in 302 groundwater samples. We show Halon-1301 reliably inferred age, thus potentially becoming a useful groundwater age tracer where other tracers are compromised.

The North China Plain (NCP), as the interest region in this study, is one of the most uniformly and extensively altered areas due to overexploitation of groundwater by humans. Here, we use GRACE and GPS to study the seasonal and long-term mass change and its resulting vertical displacement. We also removed the vertical rates, which are induced by terrestrial water storage (TWS) from GPS-derived data to obtain the corrected vertical velocities caused by tectonic movement and human activities.

The remaining populations of the endangered dwarf wedgemussel (DWM) (Alasmidonta heterodon) in the upper Delaware River, northeastern USA, were thought to be located in areas of substantial groundwater discharge to the river. Physical, thermal, and geophysical methods applied at several spatial scales indicate that DWM are located within or directly downstream of areas of substantial groundwater discharge to the river. DWM may depend on groundwater discharge for their survival.

In this study, the influence of surface water–groundwater interaction on the nutrient flux in a lowland karst catchment in western Ireland was investigated with the aid of alkalinity sampling and a hydrological model. Results indicated that denitrification within a number of ephemeral lakes is the main process reducing nitrogen concentrations within the turloughs, whereas phosphorus loss is thought to occur mostly via sedimentation and subsequent soil deposition.

Low permeability sediments and rock can leak slowly, yet can act as important barriers to flow for resource development and for waste sequestration. Relatively rapid and reliable hydraulic tests of "tight" geological materials are possible by accelerating gravity. Results from geotechnical centrifuge testing of drill core and in situ pore pressure monitoring were compared with a regional flow model, and considered in the context of inherent geological variability at site and formation scale.

We assess the potential of Halon-1301 as a new groundwater age tracer, which had not been assessed in detail. We determine Halon-1301 and infer age in 17 New Zealand groundwater samples and various modern waters. Halon-1301 reliably inferred age in 71% of the sites within 1 SD of the ages inferred from tritium and SF6. The remaining (anoxic) waters show reduced concentrations of Halon-1301 along with even further reduced concentrations of CFCs. The reason(s) for this need to be further assessed.

The crystalline rock aquifers of the Armorican Massif present clear evidence of a marine origin of the saline component in the fluids on the regional scale. High chloride concentrations are attributed to three past marine transgressions. The relationship between chloride concentration and transgression age provides constraints for the timescales of fluid circulation. This time frame is useful information for developing conceptual models of the paleo-functioning of Armorican aquifers.

Short summary
We studied groundwater near outlet glaciers of the main Icelandic ice cap. We acquired new data in the field. Two distinct groundwater compartments and their characteristics are identified. We demonstrate the glacial melt recharge impact on the groundwater dynamic. Knowing groundwater systems in a glacial context is crucial to forecast the evolution under climate change of water resources and of potential flood and landslide hazards.
