Ледники Арктики, вулкан в Перу и русский голод
Группа, изучающая российские ледники, нашла подтверждение тому, что извержение вулкана в южном Перу изменило климат планеты в начале 17го века.
Минимальные свидетельства наличия углерода вечной мерзлоты в реке Колыме в Сибири
Новое исследование показало, что арктические реки в настоящее время переносят ограниченное количество растворенного органического углерода из вечной мерзлоты, что имеет значение для понимания изменения углеродного цикла в регионе и его потенциальной возможности ускорить изменение климата.
Paleostorm Chasers Test a New Detection Tool
A method typically used to date sediments shows promise for documenting tropical storms through history—information needed for future projections of storm activity.
Shifts in Tectonic Plates Change Biodiversity
A 36-million-year cycle of marine biodiversity booms and busts matches the movements of plate tectonics, linking what happens deep below the ocean to what’s happening in it.
Natural Floodplains Are Quickly Vanishing
From 1992 to 2019, 600,000 square kilometers of natural floodplains were lost globally due to land conversion.
True North, Strong and Free—And Better Oriented
Researchers explored a method for locating true north using the polarization patterns of daylight.
Eclipse Records Pin Dates of 12th and 13th Century Eruptions
Ancient accounts of dark and blood-red moons help scientists peek at past eruptions and their effect on global climate.
Uncovering Mantle Heterogeneities Beneath Drifting Continents
Computational models of the composition and volumes of magmas during continental rifting evolution provide clues on the heterogeneities of the deep melting mantle.
Seismometers Listening at Rivers to Measure Sediment Transport
Bedload sediment, transported throughout an alpine catchment by a flood, was remotely tracked in detail by analyzing the ground vibrations recorded by a network of 24 seismic sensors.
Source Selection Essential to Inter-Source Cross-Correlation
Inter-source correlograms yield coherent signals upon careful consideration of source mechanisms and source-receiver geometry, affording new means of characterizing planetary interiors.
