Scientists plan to build on information they gathered last year, in a 10-day project starting in early March. Last year scientists made a major breakthrough when they recorded images of the Pink and White terraces on the lake floor.

Until last year it was thought the Terraces were destroyed in the 1886 Mount Tarawera eruption. Next month's project will remap the lake bed at a higher resolution than the map compiled last year, and will use seismic equipment to get a clearer picture of the geological structures under the lake floor. "Lake Rotomahana is no pushover and it's been slow to yield it secrets.

After being shrouded in mystery for over 100 years, modern technology is slowly peeling back the layers of what is a unique natural environment," project leader Cornel de Ronde said.
