Grazing by sea urchins is a potential co‐driver of Greenland kelp forest distribution

open access: yesLimnology and Oceanography, EarlyView.
Abstract Grazing by sea urchins is a main driver of kelp forest dynamics causing shifts from kelp forests to urchin barrens in the temperate region but there is limited information on such patterns from the Arctic region. Based on information from 132 underwater video transects along Greenland's West Coast at 59.9–77.8°N, we explored the distribution ...

Ice thickness regulates heat flux in permanently ice‐covered lakes

open access: yesLimnology and Oceanography, EarlyView.
Abstract The permanently ice‐covered lakes of Taylor Valley, Antarctica, are rare ecosystems where permanent ice cover and year‐round vertically stable water columns provide critical redox zones for cold‐adapted microorganisms. Using 30 yr of limnological data from the McMurdo Dry Valleys Long‐Term Ecological Research program, we assessed the water ...

Ascidians increase in abundance on tropicalized reefs and may enhance benthic nitrous oxide production

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrous oxide (N2O) is an ozone‐depleting greenhouse gas that has a global warming potential nearly 300 times greater than carbon dioxide. Although the oceans contribute about 21% of atmospheric global N2O emissions, we know relatively little about N2O dynamics in nearshore systems. Here, we document the fourfold increase in the abundance of a
