产量将与季节性分层的中部和北部地区地表水域的春季水华有关。预计约40%的新产量将出现在沿海水域，而其余的新产量预计将发生在夏季与锋面相关的次表层叶绿素峰值。通过考虑热、风和养分有效性的年际变化(光能和潮汐能量输入被视为年际不变)，估计了不同地区新生产量的年际变化。分析表明，近几十年来，沿海水域的新产量可能增加了约25%。？1998国际海洋勘探理事会
production will be associated with the spring bloom in the surface waters of the seasonally stratified central and northern regions. About 40% is predicted to occur in the coastal waters while the remaining new production is predicted to take place in subsurface chlorophyll peaks occurring in association with fronts during summer months. By considering inter-annual variation in heat, wind, and nutrient availability (light and tidal energy input are treated as non-varying from year to year), the inter-annual variability in the new production in diVerent regions is estimated. The analysis indicates that new production in the coastal waters may have increased by about 25% in recent decades. ? 1998 International Council for the Exploration of the Sea
