Phytoplankton Composition in a Borrow Pit Lake in Virginia

The phytoplankton assemblages in Lake Trashmore, Virginia, a borrow pit, were dominated by centric diatoms and cyanobacteria, with seasonal pulses of cryptomonads, euglenoids, and chlorophyceans. Ninety species were identified and their abundance levels noted for a 12-month period

Marine Litter : Technical Recommendations for the Implementation of MSFD Requirements

As a follow up to the Commission Decision on criteria and methodological standards on good environmental status (GES) of marine waters (Commission Decision 2010/477/EU), the Marine Directors requested Directorate General Environment in 2010 to establish a technical subgroup under the Working Group on GES in relation to the Marine Strategy Framework Directive 2008/56/EC (WG GES) for further development of Descriptor 10 Marine Litter and Descriptor 11 Noise/Energy. This report compiles the recommendations regarding Descriptor 10, Marine Litter. The implementation of provisons under MSFD Descriptor 10 as described in the Commission Decision 2010/477/EU is in its first step depending on the availability of appropriate monitoring tools.The group has investigated the monitoring approaches for marine litter and provides a set of monitoring tools which can be employed for that purpose.There are gaps in the regional applicability and differences in the maturity of some tools. There is need for further harmonization and collaborative activities in order to allow EU MS the future reporting of environmental trends and thus the verification of measures against marine litter.JRC.H.5-Rural, water and ecosystem resource

Baseline for beached marine debris on Sand Island, Midway Atoll

Baseline measurements were made of the amount and weight of beached marine debris on Sand Island, Midway Atoll, June 2008–July 2010. On 23 surveys, 32,696 total debris objects (identifiable items and pieces) were collected; total weight was 740.4 kg. Seventy-two percent of the total was pieces; 91% of the pieces were made of plastic materials. Pieces were composed primarily of polyethylene and polypropylene. Identifiable items were 28% of the total; 88% of the identifiable items were in the fishing/aquaculture/ shipping-related and beverage/household products-related categories. Identifiable items were lowest during April–August, while pieces were at their lowest during June–August. Sites facing the North Pacific Gyre received the most debris and proportionately more pieces. More debris tended to be found on Sand Island when the Subtropical Convergence Zone was closer to the Atoll. This information can be used for potential mitigation and to understand the impacts of large-scale events such as the 2011 Japanese tsunami
