Lake Tutira is a scenic spot on the route between Napier and Wairoa in northern Hawkes Bay. It is in a very rural setting, surrounded by steep hillsides and farmland. The landscape around the lake contains several powerful geological stories. The first is that the hills themselves, made up of rocks that are about 1.8 […]

Along with Waipatiki, another excellent Hawkes Bay locality for looking at rocks laid down over a cycle of sea level change is Darkeys Spur, about twenty minutes by car west of Lake Tutira. The road is very narrow and care should be exercised to park safely and watch out for vehicles. Fortunately the road is

Waipatiki Beach north of Napier is a great place for family holidays in the summer. It is enclosed by cliffs at either end that happen to provide one of Hawkes Bay’s many classic geological sites. (for more geological and access information see also www.geotrips.org.nz/trip.html?id=24) A track leading south of the beach takes you to a good view of
Over the last two weeks, GNS Science, with support from the Todd Foundation, The Royal Society and the National Aquarium in Napier, has been running a ‘Dinosaurs and Disasters Geocamp’ for a group of Hawkes Bay Intermediate level students and teachers. The participants investigated many landforms and cliff sections around Hawkes Bay. GNS Science geologists

Following last weeks’ multibeam sonar survey, the bed of Lake Rotomahana has now been mapped to a resolution of half a metre, bringing to light a mass of detail hitherto unknown to scientists. The first photo shows last year’s map which was made with the assistance of WHOI (Wood’s Hole Oceanographic Institution). The resolution of

The Seismic Survey of Lake Rotomahana is proceeding well this week. Whilst it is being led by GNS Science, the University of Waikato and NIWA are providing technical assistance with some of the equipment being used. The first photo shows the survey boat being loaded with the the cable that contains the hydrophones. These pick

This week I am revisiting Lake Rotomahana with Cornel de Ronde and two surveyors from IXSurvey, Mark Matthews and Dave Mundy. Our first goal in this year’s research at the lake is to make the most detailed map possible of the lake floor. Next week we will use this detailed map to help us take

Cornel de Ronde is leading another science team to further investigate the remains of the Pink and White Terraces on Lake Rotomahana in March 2012. Last year, a sidescan sonar mounted on an autonomous underwater vehicle or AUV, produced images of parts of the Pink Terraces emerging from the thick mud on the lake floor.
