  • Using micro-organisms to monitor river health

    Monitoring changes in microscopic organisms called diatoms can assist in evaluating the quality of water over an entire river watershed. Researchers from France have developed a new index that could help Member States fulfill the EU's Water Framework Directive 2000 (WFD). The WFD aims to achieve good ecological and chemical status in surface water bodies by the year 2015. Diatoms are a type of ...

  • Successful trial for new remote Phosphate monitor

    Researchers at the UK’s Centre for Ecology & Hydrology (CEH) have conducted trials on the river Thames to evaluate a new remote phosphate monitoring technology (Cycle-P) as part of a high-frequency (hourly resolution) monitoring programme that is studying river nutrient concentrations and how they are affected by algal abundance. The monitoring system ran continuously over the summer of ...

  • Voyage to Southern Ocean to monitor greenhouse gas air-sea fluxes

    Scientists have set off from the Chilean port of Punta Arenas to spend 42 days amid the high winds and big waves of the Southern Ocean, where they will make groundbreaking measurements to explain how large amounts of climate-affecting gases move between atmosphere and sea, and vice-versa. The cruise should provide important information on factors controlling the flux of the greenhouse gas carbon ...

  • Primary Productivity Monitoring in the Antarctic using CTG FastOcean FRRf System

    Marine photosynthesis is responsible for approximately half the oxygen in our atmosphere. In other words the oxygen in every second breath we take comes from the ocean. For the last 10 years Professor Andrew McMinn and his team from the Institute for Marine and Antarctic Studies, University of Tasmania have been using a Chelsea  ...

  • Sensors in Space Allow Daily Coastal Water Quality Monitoring

    ST. PETERSBURG, Florida, August 31, 2007 (ENS) - Using data from instruments aboard two NASA satellites, Florida researchers have created a way to map the fleeting changes in coastal water quality from space - something that has long evaded researchers and coastal managers relying only on ground-based measurements. This information has direct application for resource managers working on ...

  • EPA begins summer monitoring to protect area beaches, coastal Waters and New York/New Jersey Harbor

    With the beginning of the beach season, the U.S. Environmental Protection Agency is again undertaking a beach and harbor protection program to safeguard beaches and bays in New Jersey and New York and protect the health of the people who enjoy them. EPA’s program includes helicopter surveillance for floating debris, water quality sampling and grants to support state beach protection ...

  • EPA Begins Summer Monitoring to Protect Area Beaches, Coastal Waters and New York/New Jersey Harbor

    With the beginning of the beach season, the U.S. Environmental Protection Agency is beginning its beach and harbor protection program to safeguard beaches and bays in New Jersey and New York and protect the health of the people who enjoy them. This year’s program will include helicopter surveillance for floating debris, water quality sampling and grants to support state beach protection ...

  • Growth of algae affected by ocean acidification and nutrient pollution

    Ocean acidification and eutrophication may affect the growth of microscopic algae — phytoplankton — with knock-on impacts for marine food chains and fisheries, warns a new study. By growing phytoplankton under different scenarios the researchers found that phytoplankton species are affected differently according to the acidity and nutrient content of the water. Ocean acidification is ...

  • Algal bloom in baltic sea

    This Envisat image, with courtesy of ESA, captures blue-green algae blooms filling the Baltic Sea, which is roughly 1,600km long, 190km wide and has a surface area of about 377,000 sq km. "Algae bloom" is the term used to describe the rapid multiplying of phytoplankton, microscopic marine plants that drift on or near the surface of the sea. Floating freely in the water, phytoplankton are ...


  • Observing arctic ice-edge plankton blooms from space

    Ongoing climate-driven changes to the Arctic sea-ice could have a significant impact on the blooming of tiny planktonic plants (phytoplankton) with important implications for the Arctic ecosystem, according to new research conducted by scientists at the UK\'s National Oceanography Centre (NOC). Advances in modern satellite technology offer the opportunity to observe and monitor ice-edge blooms at ...

  • The effect of global warming on eutrophication in lakes

    Shallow lakes are an important type of ecosystem that may be vulnerable to current warming trends. A recent study examines just how vulnerable they are. It indicates that climate change combined with nutrient pollution could exacerbate eutrophication and suggests nitrogen levels should be monitored. Shallow lakes are important in their support of biodiversity. However, their large ...

  • IFCB in new Long-Term Ecological Research Site

    Imaging FlowCytobot samplers (IFCBs) manufactured by McLane will be installed in a new Long Term Ecological Research (LTER) site off the Northeast coast of the United States.

  • European Space Agency contributes to ocean carbon cycle research

    The Earth’s oceans play a vital role in the carbon cycle, making it imperative that we understand marine biological activity enough to predict how our planet will react to the extra 25,000 million tonnes of carbon dioxide humans are pumping into the atmosphere annually. The colour of oceanic seawater depends largely on the number of microscopic phytoplankton, marine plants that live in the ...

  • Regional policies needed to tackle eutrophication in Europe`s seas

    Eutrophication is a serious problem in some European seas, but each sea responds differently to excessive nutrient input from human activities. For this reason, a recent study recommends that policies to address eutrophication of marine waters should be tailored to each regional sea. Marine waters that are enriched with excessive nutrients, particularly nitrogen and phosphorus, can experience ...

  • Chelsea Technologies Group is working to stop ocean stowaways

    Ballast water is critical to the safe operation of ocean-going vessels. However, during ballast water exchange, thousands of aquatic organisms and pathogens can stowaway and be transported from one part of the world to another. The transfer of these organisms in ships' ballast water can have devastating effects on the marine environment and ultimately the health and well-being of the people who ...
