1995
Ģeogrāfijas zinātņu doktores, vecākās zinātniskas līdzstrādnieces L. Glazačevas personālajā literatūras rādītājā apkopoti visi viņas no 1959. g. līdz 1994. gadam publicētie darbi. Darbu uzskaitījuma beigās uzskaitīta rediģētā literatūra, tai skaitā ari Latvijas, Lietuvas un daļēji Baltkrievijas un Krievijas teritoriju Valsts ūdens kadastra sastāvā ietilpstošie uzziņu izdevumi (Hidroloģiskās gadagrāmatas).
Possible impacts of volcanic ash emissions of Mount Etna on the primary productivity in the oligotrophic Mediterranean Sea: Results from nutrient-rel…
2013
Atmospheric deposition of volcanic ash has recently been recognized as an important nutrient source into the surface ocean. Mount Etna (Italy), one of the world's most active volcanoes, is located in the oligotrophic Mediterranean Sea (MedSea). Despite the active volcanism on Mount Etna, the biogeochemical impacts of volcanic ash fallouts on the marine primary productivity (MPP) remain largely unknown. Here we present the results of seawater nutrient release experiments with volcanic ash samples from Mount Etna that have been collected during different eruptive episodes between 2001 and 2007. Our results show that volcanic ash from Mount Etna releases significant amounts of fixed-N (35-855 …
Introduction to Hydrology
2013
Hydrology deals with the occurrence, movement, and storage of water in the earth system. Hydrologic science comprises understanding the underlying physical and stochastic processes involved and estimating the quantity and quality of water in the various phases and stores. The study of hydrology also includes quantifying the effects of such human interventions on the natural system at watershed, river basin, regional, country, continental, and global scales. The process of water circulating from precipitation in the atmosphere falling to the ground, traveling through a river basin (or through the entire earth system), and then evaporating back to the atmosphere is known as the hydrologic cyc…
