Nutrient over-enrichment is one of the classic triggering mechanisms for occurrence cyanobacteria blooms in aquatic ecosystems. In Baltic Sea, regularly occur late summer months and form nuisance accumulations surface waters their abundance has intensified significantly past 50 years attributed to human-induced eutrophication. However, natural during Holocene debated. this study, we present records pigments, water column redox proxies, nitrogen isotopic signatures ca. 8000 from Sea sediment...
From June to August 2018, the eruption of Kīlauea volcano on island Hawai'i injected millions cubic meters molten lava into nutrient-poor waters North Pacific Subtropical Gyre. The lava-impacted seawater was characterized by high concentrations metals and nutrients that stimulated phytoplankton growth, resulting in an extensive plume chlorophyll a detectable satellite. Chemical molecular evidence revealed this biological response hinged unexpectedly nitrate, despite negligible quantities...

The 2018 eruption of Kīlauea was associated with massive input molten lava into the coastal ocean, which altered seawater chemistry and increased phytoplankton production. In plumes advected away from site entry, we observed elevated concentrations over a dozen metals relative to background unique isotopic compositions Fe, Cu, Ni, Cd Zn. δ56Fe iron released lower than basaltic, riverine Hawaiʻi, but similar observations other high-temperature hydrothermal vent fluids. However, rapid...
Biological nutrient removal is a process commonly used in water resource recovery facilities to reduce dissolved inorganic nitrogen (DIN) concentrations effluent; this less effective at removing all of the effluent organic (EDON). The goal study was investigate fate EDON after it undergoes disinfection and enters receiving waters. authors quantified abiotic effects exposure sunlight, increased salinity, combination two factors. Effluent showed significant breakdown during (UV chlorine) when...
Organic matter (OM) is comprised of a complex mixture substrates, which are difficult to fully characterize. Therefore range analytical approaches applied provide better understanding the dynamics and biogeochemical cycling aquatic system. One approach UV-Visible spectroscopy, includes measurements spectral absorption fluorescence colored fluorescent fractions dissolved OM (DOM, CDOM FDOM). In this study characterized by excitation-emission matrix spectroscopy on alkaline extracted DOM from...

Abstract The 2018, subaerial eruption of Kīlauea volcano, Hawaii, resulted in a 5‐km‐long stretch coastline that actively drained lava into the ocean. Nutrients were added to surrounding ocean through dissolution basaltic rock and thermal upwelling deep water, thereby fueling large phytoplankton bloom. Lava‐impacted, surface seawater had high suspended particle loads, concentrations chlorophyll, silicic acid, phosphate (P i ), nitrate, iron elevated up 12, 36, 5, 960, 1,400 times,...
