This week we are beginning our Full Length Mississippi series, and we will team back up with Mike Link and Kate Crawley. Link and Crawley highlighted pieces of their Full Circle Superior journey with the GLOBE Scientists’ Blog last year through a series of posts, the first of which you can read here . They are starting on a new adventure and commitment to the issue of fresh water: a ...

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).

We have a guest blogger this week. Mike Linke is posting his second blog in a series about his walk with his wife, Kate Crowley, around Lake Superior.
This is the second in a series about the science of Full Circle Superior; a walk around the world’s largest freshwater lake. You can read the first blog post here. My wife, Kate Crowley, and I determined that we would be the first couple to walk around this lake, trying ...

The Mississippi River is the lifeblood of New Orleans and has so impacted the city that the city was actually developed around it. The first buildings were constructed around the river edge, which has the highest ground, and now ...

Nitrogen is an important molecule that makes up nearly 78 percent of the atmosphere. Burning fossil fuels and using fertilizers for agriculture are two ways that this number can increase. But the atmosphere isn’t the only place that nitrogen is found – it is also found in bodies of water. Of the nitrogen that is spread in fertilizers, only 25-30 percent is absorbed by plants, so that leaves a lot of nitrogen left to either be absorbed by the atmosphere or into water. Figure 1 shows the intricacies of the nitrogen cycle, from Physical Geography.net’s Fundamentals ...
Sometimes in a rapidly changing world, it is difficult to see the effects that small changes in human lifestyle can have on not only climate, but on ecosystems. Various countries and international organizations are working to pass legislation to ensure change. One such case of legislation working is being observed in the San Francisco Bay – the return of harbor porpoises. This was recently reported in the QUEST biology blog .
The map below shows the location of the San Francisco Bay, marked by the bubble with an A, from Google.
In 1972, ...

Late last week, Pacific Ocean visitors near San Diego, California, USA were able to see an amazing sight that doesn’t happen very often… glowing waves!
So what exactly is the process that causes the glowing waves?
Algae! This particular type of algae, Lingulodinium polyedrum , began blooming in late August. During the day, the waters off the coast of California turn a brownish-red color, according to The University of California – San Diego scientists. Take a look at what this microorganism looks like under a microscope:
