  • Water quality information in Hawaii

    New information about water quality is now available to people living, working, and playing near Hawaii. U.S. Integrated Ocean Observing System (IOOS®) partners located within the Pacific Islands region recently installed new nutrient sensors on two water quality buoys located at Kilo Nalu and near the Ala Wai outflow. These new sensors will provide early warning of storm runoff or other poor ...

  • Trees could be used to monitor air pollution simply and cheaply

    It may be possible to use trees to monitor levels of air pollution in cities, new research suggests. A Belgian study found evidence that leaves of urban trees change both chemically and physiologically when exposed to different levels of air pollution. If these changes are carefully quantified, trees could provide cheap and widespread ‘bio-indicators’, the study’s authors ...

  • N.C. research-’artificial leaf’ & electricity

    Are you aware that a North Carolina State University team has demonstrated that water gel-based solar devices (known as: “artificial leaves”) can work like solar cells to create electricity? The analysis has been published on-line in the Journal of Materials Chemistry by Doctor Orlin Velev, an Invista Professor of Chemical and Bio-molecular Engineering. The studies prove the concept ...


  • 2016 Student Equipment Loan Program

    Sea-Bird is happy to announce the recipients of the 2016 Graduate Student Equipment Loan Awards. Michael Acquafredda is a graduate student at Rutgers University. He will be using two WET Labs ECO FLNTUs and one WET Labs Water Quality Monitor at shallow, subtidal aquaculture sites along the New Jersey shoreline to study the effect of food availability (i.e., chlorophyll), turbidity, salinity, and ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • How valuable are satellite observations of seawater quality?

    Global Earth Observation (GEO), such as satellite observations, helps manage environmental resources and prevent disasters. However, they are expensive. A recent study proposes a framework to assess the value of GEOs in which stakeholders are consulted. GEO consists of all observational information about the state of the world, including satellite observations and 'in situ' information. Many ...
