Based on the results of expeditionary studies (July 2021), geochemical features thermal waters (natural manifestations and borehole waters) discharging near or directly Sea Okhotsk Pacific coasts central part Iturup Island were considered: Reidovskie, Lososevye, Cape Konakov, Goryachie Klyuchi, Dachnye, water-recreational complex «Vannochki». The springs (with exception Lososevye) belong to sub...

In this paper, the non-Fourier heat conduction in a semi-infinite body was examined. The heat wave non-Fourier heat conduction model was used for thermal analysis. Thermal conductivity was assumed temperature-dependent which resulted in a non-linear equation. The heat source was also considered temperature-dependent which resulted in a non-homogeneous equation. The Mac-Cormack predictor-correct...

Abstract. In inland settings, groundwater discharge thermally modulates receiving surface water bodies and provides localized thermal refuges; however, the influence of intertidal springs on coastal waters their sensitivity to climate change are not well studied. We addressed this knowledge gap with a field- model-based study threatened lagoon ecosystem in southeastern Canada. paired analyses d...

Glycerol dialkyl glycerol tetraethers (GDGTs) found in hot springs reflect the abundance and community structure of Archaea in these extreme environments. The relationships between GDGTs, archaeal communities, and physical or geochemical variables are underexamined to date and when reported often result in conflicting interpretations. Here, we examined profiles of GDGTs from pure cultures of Cr...

Abstract The Songwe geothermal prospect is situated in western Tanzania the Rukwa Rift of branch East African System. Thermal springs discharge along NW–SE oriented fracture zones two separate areas: main graben (Iyola, Main springs, Rambo and Kaguri) eastern (Ikumbi). Lithologies forming filling are metamorphic gneiss shist as basement rocks, overlain by Karoo sandstones, Red both silt- sandst...
