      Anderson, Donald M.; Laycock, Maurice; Rubio, Fernando (Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)
      At the core of all national harmful algal bloom (HAB) programs are the monitoring programs needed to detect HAB toxins in shellfish, fish, water, or other resources sufficiently early to take management actions (Anderson ...
    • Appendix 3. Methods for measuring transparent exopolymer particles and their precursors in seawater. 

      Villacorte, Loreen O.; Schippers, Jan C.; Kennedy, Maria D. (Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)
      Transparent exopolymer particles (TEP) and their precursors produced by phyto-/bacterioplankton in fresh and marine aquatic environments are increasingly considered as a major cause of organic/particulate fouling in MF/UF ...
    • Appendix 4. Preservatives and methods for algal cell enumeration. 

      Anderson, Donald M.; Karlson, Bengt (Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)
      There are multiple ways to preserve phytoplankton samples and determine the algal species composition and abundance. This Appendix provides details on some of the most common methods. Additional relevant publications are ...
    • Appendix 5. Autopsy and cleaning of reverse osmosis elements affected by harmful algal bloom-contaminated seawater. 

      Peña, Nuria; Chesters, Steve; Dixon, Mike B.; Boerlage, Siobhan F. E. (Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)
      Following an algal bloom, if a change is observed in the reverse osmosis (RO) performance, an initial visual plant inspection should be carried out, including looking at and removing cartridge filters and membrane elements ...
    • Black Sea data management guide. 

      Intergovernmental Oceanographic Commission (UNESCO-IOC, Paris, France, 2002)
      The material on the "Black Sea Data Management Guide" are prepared in accordance with the working plans of the IOC Committee on International Data and Information Exchange (IODE) and its regional component in the Black Sea ...
