Middle-school students in Nova Scotia will be diving into the world’s underwater ecosystems through a new interactive program.
Ocean School, developed by Dalhousie University and the National Film Board, combines video footage with information provided by marine scientists.
DetailsMarine phytoplankton account for approximately half of the production of organic matter on earth, support virtually all marine ecosystems, constrain fisheries yields, and influence climate and weather. Despite this importance, long-term trajectories of phytoplankton abundance or biomass are difficult to estimate, and the extent of changes is unresolved. Here, we use a new, publicly-available database of historical shipboard oceanographic measurements to estimate long-term changes in chlorophyll concentration from 1890 to 2010.
