AACCRE Canadian High Arctic expedition 2019

Our second AACCRE trip in 2019 was quite an adventure into the Canadian High Arctic, based mainly from the hamlet of Aujuittuq (Grise Fiord), as well as a lesson in Arctic field logistics! Fortunately we had great support from Blackfeather and the Flight Centre…excellent resources and highly recommended for remote travel. Our basic travelogue is […]

A few thoughts on how climate change could affect volcanoes

First, it is important to understand that Earth’s climatic and volcanic systems are absolutely linked, in the short term and in the long term. Volcanic eruptions send hot gases and tiny solid particles into the atmosphere (though for all but the biggest eruptions this is short term), they form tall mountains that influence long term […]

Iskut volcanic field

Overview of Iskut-Hoodoo area

Our 2017 fieldwork was just the latest installment of research in the Iskut River area over the past 25+ years. A number of studies have been previously done in the area, dating back to the earliest geologic explorers like F.A. Kerr. He travelled up the Iskut River in the earlier parts of the 20th century, […]

Hoodoo 2017: Vancouver to Stewart BC

Trip up: 30 July-1 August 2017 Our trip to Hoodoo Mtn volcano in 2017 was a long, complex but beautiful and interesting journey! Two members of the expedition (Will K and myself) flew in to Vancouver BC to load up on field gear for the trip. We were worried about the drive up, because BC […]

Hoodoo Expedition 2017

From 2 August to 11 August I revisited Hoodoo Mountain volcano, located along the lower Iskut River, in the Coast Mountains of British Columbia, Canada. This year was the 25th anniversary of my first visit to the volcano as part of my PhD research, in the summer of 1993. I have been to Hoodoo in […]

Will pillow plunging be a new trend?

Today was largely about volcanic trends in plunging pillow lavas. We measured orientations of almost 250 pillow lavas along four different walls in a pillow quarry. We don’t have the data stereo-netted yet, but looking at pillows in minute detail is pretty pleasant if not locally positively perplexing…which way do you think this pillow is […]

Pillows galore

The started out looking to have great pillow promise, but by late afternoon the weather was only pleasant for lavas born in water. However, we gigapaned aplenty and picked apart pillows for senior projects. We even found some dualin’ MCJBs (massive column-jointed basalt) arguing about whether they were steeply dipping subaqueous sheets or pillow plumbing […]

Xenoliths, Dikes and more Pillows

Had a big day on Thursday! We started off with a quick stop at Grænvatn (minus Meagen, Adam and Michael, who had left for the U.S. :(, a small acidic lake filling some explosive craters in the Krusivik area of the Reykjanes Peninsula (see pic below). We wanted to examine the gabbroic xenoliths that were […]

Playing with pillows

Overview The blog will try to keep people updated on progress of our Dickinson-Wooster expedition in Iceland. We (3 faculty + 6 students) are mapping pillow lavas on the Reykjanes Peninsula, courtesy of several well-placed quarries. The aim of our project is to better understand what happens when volcanic fissures open beneath large ice sheets. […]

Reflections on Russia

These posts will highlight a few of the adventures I’ve had this spring while on sabbatical. I was incredibly fortunate to have the opportunity to go to the far east of Russia two times: once in late January and once in March/April. I traveled to observe, monitor, sample and measure the properties of lavas being […]
