A Less Hardy Hardiness Map The USDA has unveiled a new version of its plant hardiness map, which gardeners use to gauge which plants will survive in which climate zone. (Check your nearest seed packet.) In the newest iteration, many zones have shifted northward because winters aren’t as cold as they were 22 years ago […]
By Ludovic Brucker The main objective of deep field traverses like ours is to make in-situ measurements and collect samples, which obviously cannot be done from air or space. So, during the 2010-11 and 2011-12 SEAT field seasons, we have been taking in-situ snow and radar measurements. We typically had two different types of days […]
By Michelle Koutnik Each of our six different camping sites consisted of one cook tent, four sleeping tents, and a bathroom area (more on that later). The cook tent was a “Scott” tent, which is an enduring style and named for the polar explorer Robert Scott. It was a tight space for five people but […]
By Clement Miege Hi there! After more than three weeks spent in the field, our team is very happy to be finally back, with many memories of the traverse. This year has been a very intense experience and I would like to tell you a little more about this expedition. I will focus on the […]
The GPM (Global Precipitation Measurement) Cold-season Precipitation Experiment (GCPEx) will be conducted in cooperation with Environment Canada in Ontario, Canada from January 17th to February 29th, 2012. The overarching goal of GCPEx is to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow through the collection of microphysical […]
By Michelle Koutnik Now for a recap of our adventure! We arrived in Christchurch on November 19 and returned there on January 5. We spent 17 days in McMurdo before leaving to Byrd camp on December 7. It took only a few days to prepare for the traverse and we left Byrd camp on December […]
By Bob Bindschadler Christchurch (New Zealand), 18 January — This will be my last entry in this season’s blog. I had hoped to tell a different tale the past two months —one of successful science being done in a harsh, remote place by hardy individuals dedicated to getting information that had direct relevance to your […]
It’s been a really active time for the Earth Observatory and volcanoes. In the past three weeks, we’ve posted images of a night-time eruption of Shiveluch, ongoing activity at Puyehue–Cordón Caulle, daytime activity at the Kizimen Volcano, and my own favorite, a brand new island in the Red Sea. And those are just the images […]
By Bob Bindschadler McMurdo (Antarctica), 14 January — Delayed flights seem to be the rule this season. Our flight to Christchurch was cancelled late Thursday night because of expected bad weather here. On the next try, there was a mechanical problem that required a part that had to be shipped to Christchurch, so I’m still in […]
The new feature story, Seeing Forests for the Trees and the Carbon, discusses the need to form a three-dimensional picture of the world’s forests. Such a three-dimensional picture includes tree canopy height (below). Although canopy height in the Amazon Rainforest doesn’t match those of the Pacific Northwest or Southeast Asia, it still far exceeds the […]
