No published reports exist on the early stages in the establishment and succession of microbial communities and associated chemical and geochemical transformations in aquatic environments shortly after a volcanic event. Much of our understanding of volcanic lakes has come from studies carried out years to centuries after the eruption, when the lakes were already stabilized. Here we document the chemical and microbiological responses of lakes and hydrothermal environments in the blast zone near… Expand

Initial Effects of the Mount St. Helens Eruption on Nitrogen Cycle and Related Chemical Processes in Ryan Lake
TLDR
The important role of nitrogen as these lakes recover from the cataclysmic eruption and proceed back towards their prior status as oligotrophic alpine lakes is emphasized. Expand
Nitrogen Cycling in Altered and Newly Created Lakes Near the Mount St. Helens Volcano
TLDR
Microbial and chemical measurements show: assimilative N-cycle reactions and phosphate limitation playing increasingly important roles in aerobic strata; and dissimilative nitrogen and other... Expand
Changes in dissolved organic material in Spirit Lake, Washington, USA
The eruption of Mount St. Helens on May 18, 1980 drastically changed lakes within the blast-zone area devastated by the volcanoe (fig. 1). Pyroclasticand debris-avalanche deposits entered Spirit… Expand
Rapid changes in dissolved humic substances in Spirit Lake and South Fork Castle Lake, Washington
One major effect of the eruption of Mount St. Helens, Washington, was a large increase of dissolved organic material in the lakes of the area devastated near the volcano. Much of this material was… Expand
ALGAL COMMUNITIES OF SPRINGS AND STREAMS IN THE MT. ST. HELENS REGION, WASHINGTON, U.S.A. FOLLOWING THE MAY 1980 ERUPTION 1
TLDR
Within 15 months or less of the eruption, algal communities were established throughout the blast impact area, but as a result of the initial and continued disturbance these communities remained in an early successional stage. Expand
QUALITATIVE AND QUANTITATIVE OBSERVATIONS ON AQUATIC ALGAL COMMUNITIES AND RECOLONIZATION WITHIN THE BLAST ZONE OF MT. ST. HELENS, 1980 AND 1981 1
Despite the destruction and total rearrangement of much of the area north of Mt St. Helens, many different species of algae became established in the aquatic systems located in the blast zone within… Expand
Posteruption Response of Phytoplankton and Zooplankton Communities in Spirit Lake, Mount St. Helens, Washington
TLDR
The rapid recovery of Spirit Lake demonstrated the vigor and resiliency of lake ecosystems and particularly plankton communities. Expand
Methane production and oxidation in lakes impacted by the May 18, 1980 Eruption of Mount St. Helens
The concentrations of CH{sub 4} and CH{sub 4} oxidation rates were measured in lakes impacted by the May 18, 1980 eruption of Mount St. Helens. The highest CH{sub 4} concentrations were recorded… Expand
Diatom-derived palaeoconductivity estimates for Lake Awassa, Ethiopia: evidence for pulsed inflows of saline groundwater
A 6,500-year diatom stratigraphy has been used to infer hydrochemical changes in Lake Awassa, a topographically closed oligosaline lake in the Ethiopian Rift Valley. Conductivity was high from… Expand
Submarine hydrothermal vents and associated gradient environments as sites for the origin and evolution of life
Submarine hydrothermal vents are the only comtemporary geological environment which may be called truly primeval; they continue to be a major source of gases and dissolved elements to the modern… Expand

TLDR
Samples of sediment from Lake St. George, Ontario, Canada, were incubated in the laboratory under an initially aerobic gas phase and under anaerobic conditions and there was O(2)-dependent production of nitrous oxide, which was inhibited by acetylene and by nitrapyrin, suggesting that coupled nitrification-denitrification was responsible.

In vitro biological tests showed the ash from the 18 May 1980 eruption of Mount St. Helens to be nontoxic to alveolar macrophages, which are an important part of the lungs' natural clearance mechanism. Expand

Denitrification and Nitrogen Fixation in Alaskan Continental Shelf Sediments
TLDR
Long-term exposure was necessary before a reduction in nitrogen fixation rates was observed; unamended rates of denitrification but not potential denitrified rates (NO(3) added) were depressed after exposure to hydrocarbons. Expand
Nitrogen Fixation in a Salt Marsh
TLDR
The lower zones of salt marshes, in common with most marine habitats, are deficient in available combined nitrogen and therefore any contribution made by nitrogenfixing organisms to the nitrogen status of the marsh is likely to be significant. Expand

TLDR
Oxygen was found to exert little effect on the observed acetylene reduction activity, indicating that stable aerobic and anaerobic microenvironments exist in the surface layer of marsh sediments. Expand
