Catchment areas on volcanic territories in different regions are of great interest since they enriched with nutrients that contribute significantly to coastal ecosystems. The Kamchatka Peninsula is one the most active world; however, date, chemistry its river waters and state ecosystems remain understudied connection volcanism. two rivers under study largest this region. River, unlike Penzhina drains territories, including volcanoes Klyuchevskaya group Shiveluch Volcano. mouth River has been...
Understanding the factors that control carbonate systems is an important goal due to complex interactions between hydrophysical and chemical–biological conditions in coastal basins. The results of this paper present state system Penzhina Bay its adjacent waters—the Shelikhov Gulf—in July 2023, during spring tides with 13 m height. area we studied included length largest river region, River, from peak summer flood boundary Gulf (the Sea Okhotsk). This unique dynamic basin, a about 800 km, was...
Abstract Chaun Bay, located on the fringe of East Siberian Sea, has been described since mid-20th century to support a unique marine ecosystem that is atypical for local Arctic. Here we use ship-board physical, biogeochemical and geological measurements taken in October 2020, along with hydrographic observations from land-fast ice April 2023, demonstrate these warm-water biological communities are supported by hydrothermal submarine groundwater discharge delivers heat, salinity, nutrients,...
Hydrological conditions are an important factor for aquatic ecosystems. Their contribution to stimulating phytoplankton bloom in eutrophic estuaries is not quite clear. We present the results of outbreak a event observed Razdolnaya R. estuary 2022 from January 22 February 23, when was covered by ice. The spreads over 21 km river mouth bar upstream near-bottom layer below halocline. Chl-a concentration area increased 15 100 μg/L, and dissolved oxygen 350 567 μmol/kg at rate 11 μmol/(kg day)...
The water dynamics and distribution of the sea grass Zostera marina are investigated as factors curative mud forming in Voevoda Bay. currents measured directly. closed circulation is formed middle part bay by prevailing winds: anticyclonic northwestern wind cyclonic southeastern wind. researched divers. Its highest biomass observed on shallows where projective coating 100 % mean 3 kg/m 2 (wet weight). Bottom sediments depth acoustic basement mapped using seismoacoustic method. maximal...
Nutrient fluxes with river runoff can largely determine the state of coastal water ecosystems. The Vilyuchinskaya and Avachinskaya Bays Kamchatka Peninsula were surveyed on 4–5 July 2022, just after peak spring–summer flood Vilyucha Avacha Rivers associated snow melting in volcanic areas. Additionally, sampling was performed December period winter low water. A general undersaturation CO2 surface waters observed Bays. Strong supersaturation near-bottom observed, due to microbial destruction...
Chemical water parameters in the Partizanskaya River estuary were measured on July 18–19, 2012 conditions of low discharge (20.1 m3 /s). In these conditions, cline salt at bottom penetrated up to 11 km upstream from river mouth and fresh passed estuarine zone mixing approximately 2 days. Salt composition mixed had conservative dependence salinity. By dynamical signs, could be divided into two zones: i) active exchange between surface freshwater layer salted distance 5.5 first sandy riverbank...
