Increased risk of cyanobacterial blooms in northern high‐latitude lakes through climate warming and phosphorus enrichment
Harmful cyanobacterial blooms are an increasing problem at many locations throughout the
world but are rarely reported in aquatic habitats at high latitudes. Shallow lakes are a major …

Diversity and potential activity of methanotrophs in high methane-emitting permafrost thaw ponds
Lakes and ponds derived from thawing permafrost are strong emitters of carbon dioxide and
methane to the atmosphere, but little is known about the methane oxidation processes in …

Turbulence in a small arctic pond
Small ponds, numerous throughout the Arctic, are often supersaturated with climate‐forcing
trace gases. Improving estimates of emissions requires quantifying (1) their mixing dynamics …
