On the correlation and interactions of space weather with biological indicators

1. Introduction Space weather is significantly affected by geomagnetic disturbances (GMDs) that occur during or after intense solar events such as coronal mass ejections (CMEs), which expel substantial amounts of electromagnetic particles into interplanetary space. Most of these particles collide with the magnetosphere (the outermost region of the atmosphere) where the solar wind (continuous flow of ionized particles) meets the Earth’s magnetic field and can cause compression of the magnetosphere [Gonzalez et al. 1998]. GMDs occur most frequently at the …


IGS: A Home for the Global Cryosphere

Like many glaciologists (in the broad sense – as in, cryospheric researchers, not just those who study glaciers!), my professional “home” has been the International Glaciological Society (IGS) ever since grad school; My first conference was an IGS branch meeting, I found my postdoc by networking at an IGS symposium, I have published work in IGS journals, and IGS has supported many community activities I have been a part of. But, I know there are a lot of cryospheric scientists …


Bits and Bites of Geodesy – Satellite Gravimetry: Studying Earth’s water cycle from space

During winter, mountains gain mass because of snow covering the peaks. In spring, the snow melts and flows downstream until it reaches the ocean or evaporates into the atmosphere to reach back on the surface as rain or snow. The global water cycle is very complex and essential for life on our planet. Did you know we can measure how the water is distributed by measuring its mass from space? How can satellite gravimetry collect all that information? Already since …
