Lake ice is mostly seasonal ice that forms on water bodies such as lakes and lagoons when the air temperature is below 0°C for long enough to drop the surface water temperature to or below 0°C. First, some ice crystals begin to form at the lake surface and then develop into a continuous layer that covers the surface partially or completely.

New research shows that 2,000 years ago, remnants of an Arctic ice sheet began growing again, marking the start of a new glacial period--what we commonly call an ice age. But by the 1960s, global warming had raised summer temperatures enough to reve...

As you may know, SV-POW! uses the excellent Rogue Scholar service to archive all our posts and to allocate DOIs. There's plenty more going on at Rogue Scholar, and one of the in-progress initiatives is an attempt to categorize scholarly blog posts. Martin Fenner, who created and maintains Rogue Scholar, has tentatively proposed a simple split into seven categories, and is seeking feedback.

Aberfan is located in the South Wales Valleys and developed as a coal mining village during the industrial revolution in the mid-1800s. The village is much like any of the other villages scattered across the region - rows on rows of small terrace houses, nestled into the sides and bottom of steep, glacially eroded valleys. However, this quiet, beautiful village is also known across the world for its connection to one of the UK's worst mining disasters.

Let's get the joke out of the way first, because I made it to myself more than once while finishing this piece: "explosive inside, effusive outside" is a fairly accurate description of the average Early Career Researcher trying to hold it together inside the current state of academia. Calm, composed, professionally cheerful on the surface; a small pyroclastic flow of funding anxiety, precarious contracts, growing responsibilities for the lowest payslips and looming deadlines going off somewhere just beneath it. It turns out this is also, with slightly more rigour and considerably less existential dread, a pretty good description of a silicic volcanic dome.

Needless to say, we shoved it in the spam folder.
