NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s new COral Reef Airborne Laboratory (CORAL) field campaign kicks off its data-gathering phase with an operational readiness test on Oahu, Hawaii, starting the week of June 6th. Over the next year, CORAL will conduct airborne and in-water surveys of representative coral reefs from Hawaii to Australia.

By focusing on entire reef ecosystems, CORAL scientists will get state-of-the-art insights into how biological, physical and chemical processes shape and affect the ecosystems. These data will help them answer fundamental questions about how reefs are changing globally due to the effects of climate change and human activities.

NASA takes a look at the positive and negatives of Algae

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Algae are complicated. The little plants can be both good and bad.

Single-celled algae called phytoplankton are a main source of food for fish and other aquatic life, and account for half of the photosynthetic activity on Earth—that’s good.

But certain varieties such as some cyanobacteria produce toxins that can harm humans, fish, and other animals. Under certain conditions, algae populations can grow explosively — a spectacle known as an algal bloom, which can cover hundreds of square kilometers. For example, in August 2014, a cyanobacteria outbreak in Lake Erie prompted Toledo, Ohio, officials to ban the use of drinking water supplied to more than 400,000 residents.

NASA - National Aeronautics and Space AdministrationHouston, TX – The green stuff that clouds up fish tanks – it’s not just an aesthetic annoyance. In fact, if you’ve been watching recent news of algal bloom concerns in Lake Erie, you know that the right conditions for algae can lead to contamination of local water sources, potentially impacting aquatic life and humans.

What you might not have known is that among the resources to help study this problem you will find the International Space Station’s Hyperspectral Imager for the Coastal Ocean (HICO).

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation — including stunted trees — along the edges of the frozen continent.

The team of scientists involved in the study, published online June 17th in Nature Geoscience, was led by Sarah J. Feakins of the University of Southern California in Los Angeles, and included researchers from NASA’s Jet Propulsion Laboratory in Pasadena, CA, and Louisiana State University in Baton Rouge.

Austin Peay State University professor awarded $75K state grant to study health of Red River Watershed

 

Austin Peay State UniversityDr. Jeff LebkuecherClarksville, TN – On a spring afternoon in 2010, Dr. Jeff Lebkuecher, professor of biology at Austin Peay State University, waded into a creek to collect algae floating in the water and growing on rocks.

The samples were placed in test tubes, and back in his lab inside the APSU Sundquist Science Complex, Lebkuecher noticed that the algae were thriving. This was not good news for the creek. «Read the rest of this article»
