Voyage to the base of the food chain

On the second leg of the journey around the Antarctic, the research vessel Akademik Treshnikov sets out from Tasmania to the frozen edge of Antarctica, before heading on eastwards to Chile. An oceanographer, whose knowledge of the Southern Ocean was previously limited to theory, blogs from on board. Read more

Geothermal storage for our cities

Geothermal probes and heat pumps provide an effective alternative to oil heating, but they aren’t suitable for use in densely populated areas where probes in close proximity extract too much heat from the ground. However, using probes for heat storage as well could unlock their considerable potential. Read more
