Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/30/an-interesting-relationship-soil-temperature-and-climate-change/ It seems common place that warmer air temperature leads to warmer soil temperature. And while this relationship seems intuitive, the effect isn’t always studied, especially with respect to the response from microorganisms. That is why researchers are investigating what happens when the soil temperature increases. An intricate network of soil microorganisms From: Commonwealth Scientific and Industrial Research...

Blog previously posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/16/a-tale-of-two-extremes/ Weather extremes have become a common theme in the news headlines the past few weeks. For example, nearly every part of the United States has been experiencing one of two extremes – either frigid cold or record-breaking high temperatures. Places like Arizona and California experienced below-freezing temperatures, which can have potential impacts on the crops grown in these typically balmy regions. In contrast, cities in the Southeast U.S., such as Atlanta, Georgia,...

Most trees obtain water through their massive root systems, but did you know that some trees can absorb water through their leaves as well? This ability is called foliar uptake. Scientists recently discovered that trees in cloud forests use foliar uptake to obtain water. A cloud forest is a forest that has persistent or seasonally persistent fog or low-level cloud cover. Cloud forests are usually in the tropics or subtropics, have evergreen trees (trees that don’t lose their leaves) and tend to have a lot of mosses and vegetation in the understory of the trees. Cloud Forest located...

GLOBE’s Earth as a System investigation area cultivates students’ awareness of an intricate web of global connections. Similar to real world scientists, students explore life science concepts, learning that “organisms can only survive where their needs are met.”  The Earth as a System investigation area encourages students to observe patterns and connections, such as through phenology. Phenology is the study of how living organisms respond to seasonal changes in their environment. Only through observing and measuring can we notice if changes are occurring and how they occur. For...

In the article in Nature Geoscience, it explained that such droughts can further enhance global warming. When a drought occurs, the plants wither and die and no longer uptake carbon dioxide (normally living plants serve as a carbon sink...

Storm Coming Across US If you live in the United States, you probably have heard of the snow storm crossing the country right now. There will be mountain snow in the Rockie Mountains, a potential for a blizzard from Nebraska to Wisconsin and then some snow to the Great Lakes states. The National Weather Service (NWS) definition of a blizzard is: "A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer: Sustained wind or frequent gusts to 35 miles an hour or greater; and Considerable falling and/or blowing snow (i.e.,...

Lane Community College will be embarking on a comprehensive water quality study for Russel Creek Watershed.  It owns property near the headwaters of the creek and it passes through sensitive wetlands that LCC also owns.  We will monitor water quality monthly upstream and downstream from the campus as instruments are acquired.  Russel Creek is an ephemeral stream.  First measurements 12-07-12 at the upstream sampling site near the LCC Learning Garden (our SWS-06 site).

The GLOBE surface temperature field campaign started this week with some record warm temperatures in the United States. Students in much of the United States enjoyed short sleeve weather for several days. Schools have started to post observations on the GLOBE website. The GLOBE website has been changed dramatically over the last year. The GLOBE Program Office will be adding all teachers in a bulk transfer from the old database in the near future. Many teachers have also signed up on the GLOBE webpage http://www.globe.gov and the help desk has set them up so they can enter data. The help...

Remember that the atmosphere and oceans are always moving, and in general, those movements follow a specified pattern. When the movement deviates from normal, to either an El Niño or La Niña, weather conditions in different regions of the world will respond. But who feels these effects first? Usually, equatorial countries that border the Pacific Ocean. But even these countries can...

Weather forecasts now routinely extend for five days. The recent flooding on the East Coast of the United States was forecast days in advance.

August 19, 2012 We went to a glacier in central Switzerland. It is a tourist attraction. It was the most unsustainable tourist place I have been to in my life. Usually, at tourist places, they try to have you do things that preserve the site. In the United States at the parks, you are not allowed to take anything away. Dunes are protected at the parks that have dunes along Lake Michigan, etc. But, here, there are thousands of tourists walking on the glacier, there is a cave that they carved out of the glacier, there is even a sledding area.

It is big enough that there is a lot of business but it is small enough that the streets are not clogged with cars. Maybe one of the reasons is that so many people ride bicycles. There were bikes everywhere. Sometimes the people walking have to be careful not to get run over by the bikes. We went down to the old part of Frankfurt which is near the River Main. The old town area is very cool to visit. I found it interesting that much of the old town had to be rebuilt after World...

Tree-of-heaven (Ailanthus altissima) is spreading widely throughout West Virginia and threatening the native forest ecosystems in Appalachia.  This invasive plant was introduced to the United States from China in the 1780s. The same exotic tree species was also introduced to Japan in 1860s but is not aggressive in this country. In Japan, particularly in the Kyushu Island, tree-of-heaven is rarely found in natural forest ecosystems but a few trees may be found growing in university campuses (i.e. Kyushu University), school premises and house backyards. Tree-of-heaven was initially...

It is called the tree-of-heaven (Ailanthus altissima). This trip initiated a project involving a more in-depth investigation of the competitiveness of Ailanthus as an invasive plant. With the involvement of undergraduate students in the Department of Land Resources at...

Sometimes, part of being a scientist is dealing with the unexpected. During research projects, scientists might get very surprising results. Or, something might happen to completely change the scope of the project. This is exactly what happened to a group of scientists in Chile.

They had surveyed 9 beaches in Chile when something very unexpected happened on 27 February 2010– an 8.8 magnitude earthquake hit. Seawall before and after the earthquake...
