Estimation of deep infiltration in unsaturated limestone environments using cave lidar and drip count data [PDF]

open access: yesHydrology and Earth System Sciences, 2016
Limestone aeolianites constitute karstic aquifers covering much of the western and southern Australian coastal fringe. They are a key groundwater resource for a range of industries such as winery and tourism, and provide important ecosystem services such

Molecular detection of bioluminescent dinoflagellates in surface waters of the Patagonian Shelf during early austral summer 2008 [PDF]

open access: yes, 2014
We investigated the distribution of bioluminescent dinoflagellates in the Patagonian Shelf region using “universal” PCR primers for the dinoflagellate luciferase gene.

Long-Term Spatiotemporal Variability of Whitings in Lake Geneva from Multispectral Remote Sensing and Machine Learning

open access: yesRemote Sensing, 2022
Whiting events are massive calcite precipitation events turning hardwater lake waters to a milky turquoise color. Herein, we use a multispectral remote sensing approach to describe the spatial and temporal occurrences of whitings in Lake Geneva from 2013

The Water-surface “Halo.” [PDF]

open access: yesNature, 1913
THE “Halo.” which a happy memory of eighty years enables the Rev. O. Fisher to recall in NATURE of February 6 was probably one to which the explanation offered by Dr. Franklin Parsons does not apply.

Do contaminants originating from state-of-the-art treated wastewater impact the ecological quality of surface waters? [PDF]

open access: yes, 2013
Since the 1980s, advances in wastewater treatment technology have led to considerably improved surface water quality in the urban areas of many high income countries.

Occurrence of glucocorticogenic activity in various surface waters in The Netherlands [PDF]

open access: yes, 2013
Considering the important role that surface waters serve for drinking water production, it is important to know if these resources are under the impact of contaminants.

Effects of nitrogen on nutrient-limitation in oligotrophic northern surface waters [PDF]

open access: yes, 2021
Nitrogen deposition has a potentially eutrophying impact on oligotrophic freshwaters. Here we present a data analysis and a literature review with a joint focus on nitrogen (N) limitation in oligotrophic lakes and rivers.
