and Petrology, Exploration The slopes on the semilog plot of Figure 2 for the time dependence of SO4, Ca, and Mg (corrected for natural logarithm) are between 0.11 and 0.12, or 1/τ = 1/9 = 0.11. High evaporation rates should be compensated by a decrease in the drainage rate and thus result in an increase of the residence time. Thus, the residence time for the Karymsky Lake‐Karymsky River system can be estimated as τ = Vlake/Qout = 49/5.35 ≈ 9 years.

Thus, the dynamics of two groups of lake water solutes can be predicted by a simple box model for water and solute mass balance.   --Tibetan Proverb, Images in Modeling Earth Systems (JAMES), Journal of Geophysical Research Working off-campus? Five of them appeared after the eruption.

[3] The approach used in this study is similar to those applied for other lake systems with outflow (and a constant volume, dV/dt = 0) for evaluating the dynamics of anthropogenic and natural solutes [e.g., Varekamp, 1988, 2003, 2008] and is based on a simple dynamic box model for nonreactive species [Albarède, 1995]. This gives for the Qin term a value of ~1.6 m3s−1. "Man is not made for comfort" Parents refers to a larger category under which an object falls. It is a stratovolcano located in the center of a caldera 5km in diameter. The water became acidic and enriched with sulfate and Ca (Table 1), with a composition typical for diluted acidic SO4‐Cl waters of volcano‐hydrothermal systems [e.g., Giggenbach, 1997]. The old and new hydrothermal vents, Na‐Cl in composition and poor in SO4, Ca, and Mg, currently contribute about 0.14 m3 s−1 of hot Na‐Cl water, which is 3–3.5 times higher than before the 1996 eruption.

The lake, with a surface area of ~10 km2 and a volume of ~0.5 km3, became acidic, increased its salinity to ~1000 mg/kg, and became dominated by SO42− and Ca2+.

[2008] and our data obtained in August 2012 from the middle lake site. [9] Karymsky Lake has a surface area of about 10 km2 and a flat bottom at depth ~60 m (Figure 1). The lake, with a surface area of ~10 km 2 and a volume of ~0.5 km 3, became acidic, increased its salinity to ~1000 mg/kg, and became dominated by SO 4 2− and Ca 2+.Since the eruption, the lake chemistry has evolved in a predictable manner described by simple … [15] The simplest box dynamic model for a lake‐river system has a solution C(t) = Cs + (Co − Cs)e−t/τ (equation 4) with only two parameters. Vakin and Pilipenko [1998] have mapped in detail all thermal fields as they appeared in 1996, half a year after the eruption.

They also presented the measured flow rates of thermal waters from each of nine groups of thermal springs that represent the Karymsky geothermal system.

The second group, the “hydrothermal” group, obviously has an additional source that in a first approximation can be assumed as having a constant flow rate and concentrations of components similar to those of the Akademii Nauk waters.

As a result of dilution by incoming SO4‐Ca‐Mg‐poor water, SO4, Ca, and Mg concentrations follow a simple exponential decrease with a characteristic time close to the residence time of the lake. Related to Geologic Time, Mineralogy

It is named after the Karyms, an ethnic group in Russia. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.

Karpov and Esikov [2005] presented field values of 0.175 and 0.152 m3 s−1 for the thermal input to the lake in 1997 and 1998, respectively. Geophysics, Geomagnetism [1] The 1996 short‐lived subaqueous eruption at the Karymsky caldera lake suddenly changed the composition of the lake water.
