DOI: 10.1002/2017gl074455
Abstract: We studied 38 slow slip events (SSEs) in 1997-2016 beneath the Iriomote Island, southwestern Ryukyu Arc, Japan, using continuous Global Navigation Satellite System (GNSS) data. These SSEs occur biannually on the same fault patch at… read more here.

DOI: 10.1007/s00126-020-01022-3
Abstract: Artificial hydrothermal vents, created by boreholes that discharge hydrothermal fluids and useful for observing secular changes in mineral precipitates and the chemical compositions of hydrothermal fluids, are periodically cleaned of scale deposits. Here, we report… read more here.

DOI: 10.1007/s00248-020-01583-w
Abstract: Microbial eukaryotes (protists) contribute substantially to ecological functioning in marine ecosystems, but the relative importance of factors shaping protist diversity, such as environmental selection and dispersal, remains difficult to parse. Water masses of a back-arc… read more here.
